areas of individual differences many areas you know person have and areas can be emotional areas or physical area or social area or age difference or gender difference or aptitude difference or attitude difference so individual differences have a lot of you know different areas that these differences prevail actually and everybody has different capacities to respond to the environment everybody has different capacity to behave with others and everybody has different intelligence level to you know work on different tasks and everybody has different physical appearance to you know to look like so it is individual differences are normal differences that parents and teachers should know that and today these differences we will come to know about the emotional differences among all these areas of individual differences emotional differences you know the concept of emotional differences an emotional intelligence concept is also introduced emotional emotions and feelings what are they? emotions and feelings means that a person has a very soft area of emotions every person has his emotions now how to express emotions can be different from that now emotion less some people call you emotion less because they are not so expressive so now if there are two sisters or two brothers then if their emotion expression can be positive or negative one express their emotions aggressively one express their emotions very positively and politely and modestly so this difference in emotions it is also very normal and it depends on the environment when we have four children or three or two at home then when we deal with them differently parents give someone more attention and less attention that also creates emotional disturbance and emotional differences and children think that the first child gets more importance they are given good things, they are ignored and then they show emotional reaction so the reason for emotional differences is also environment and its reason is biological so the difference in this house with the children creates emotional disturbance an emotional intelligence concept is presented according to which that will be emotional intelligence the emotion which expresses its emotions in the right way, in the right place, in the right style is called emotional intelligence that it is known that I do not express my feelings and expressions in front of everyone I have to express my feelings and emotions with whom and in what way and where I need to hide my emotions where I should stop by expressing myself this is that emotional intelligence which works to balance its feelings and emotions so this is called emotional balance to get emotional balance a person needs intelligence to tackle his or her feelings and emotions after that there is social adjustment emotional balance is very important for social adjustment people like the same thing which is emotionally stable now those who do not know when they will get angry people do not like aggressive people so the person who controls his emotions is widely accepted that is why for social adjustment there is also need of intelligence now see if you do something without looking at the situation without looking at the situation you express your emotions then that intelligent person does not say that that is why we are saying that for social adjustment or for socially acceptance we need emotional balance that the person who is very modest, polite, positive is widely accepted and people will love to make him friend and the person who is aggressive, impatient and always argue with people then people will not like him or her and they will not make him friend these are general rules for social adjustment so for better social adjustment a person needs to follow ethical rules, moral rules and also always respect for others emotions and feelings and always respect for others rights then people will accept him and will make him friend and then he will be socially adjusted well


Welcome to the hippie report, my sacred, sacred siblings. Hope you're all doing very well today. It's a beautiful day. Little gray outside. Looks like it wants to maybe flirt with raining a little bit. Which makes sense because I totally considered paying for a car wash the other day. So it makes sense that we'd be seeing rain now. What's up Tyler?  You know that's one of the nicest things you can do for anybody is let them know they matter. This is just me trying to show up and let you know that those of you that like this show, I am trying to do the show. You know, today I guess I have a little bit of a story. Allegedly, allegedly sat around my garden yesterday and tripped on LSD in an effort to sort of like ground myself and sort of, I don't know, I don't know, pull myself together. So you may have noticed there wasn't a show yesterday. Well, I was far too high, allegedly, to do any kind of show. And now, smoking this joint, I'm considering returning my emails and stuff while I go for a walk down to Main Street, Longmont, where I intend to perhaps purchase an Italian beef sandwich from Johnny's. Now Johnny's not a sponsor of the episode. You know, they're not a sponsor of the show, but they might as well be because they're wonderful, wonderful people over there and a great local company. And I eat those Italian beef sandwiches with my full, full heart and all of my gusto. You get it dry, I think. You can get it dry, wet or dipped.  But basically like, how juicy do you want your bread? Personally, I like to go for the dry and I get the juice on the side because then I get to like be much more decadent with it and I'm not dealing with just this big mess of wet bread, which is unappealing to me. Oh, thanks AJ. That's very kind. Yeah, I got a haircut and it's much shorter than my hair used to be. I probably look a little older than I did in the last episode because, well, I am a little older, a day older. But also like, I feel like when my hair is short, I just look a little bit more my age. I'm not like an old man for fuck's sake. 34, but I think I look way more 34 with short hair. With the long hair, it's a little bit more fakeable. Not that I'm trying to look young. Not really trying to look young. Sorry I'm getting distracted here, folks.  Some of them quite dramatic. So, I got friends that need my attention today so I'll be trying to spend some of my time today being a good friend. But that's tough. It's tough to be a good friend.   I didn't pack my joint very carefully and now I'm paying the price. Let us all just take a quick lesson here. When you do things half-heartedly, you can only get half-hearted results. That's my opinion. That's what just happened with my joint. I heard a very genius thing from a close friend yesterday.  And I think that is one of the more brilliant things I've heard in a while. It just seems so true. And boy, you can put that in your business context. Oh, thank you, Wayne. What a nice... I just saw your comment. You say you always look dapper and handsome. Thank you very much.   Maybe I'm just all alone about it. But every once in a while, my friends... I have very smart friends and very deep-thinking friends. And every once in a while, they kind of, I don't know, off-handedly say something that I just have to be like, oh, wait, I have to think about what you said there. I actually have a roommate that rents out this, what used to be my art studio. And every once in a while, we'll be sitting around having coffee or whatever in the morning.    When somebody says something really important and deep first thing in the morning, it seems very inconsiderate to me. That's all. Just seems inconsiderate. Inconsiderate is one of the rudest things you can make someone feel, I think. Not considered, you know? I've been studying a lot of like personal development stuff and a lot of like psychology stuff lately. And what's up, Stephen? Good to see you.  I'm just, I have friends that are therapists and sometimes data therapists. I think she's mostly in it for like a research type purpose, you know? You know, maybe she's writing some kind of paper or something. But I've been saying a lot of things like, oh, it's good to provide space.  Somebody says something interesting and I say say more. And it's like the perfect phrase to unlock someone a lot of times. And I guess I've learned that from my therapist friends.   And I hope they're all accepted. Or do you know by golly, you can always tune away. What's up, hands? Good to see you. I hope you're doing very well. I try and say hello to people when they pop through the chat here. Decided to roll myself up a joint today. The this particular strain of weed is called the cheesy fire. And it's particularly moist. I'm probably smoking it a little early in its experience. But yeah, it's not really staying lit because A, I didn't pack it very well. And B, I didn't really let it wait around as long as you're supposed to. Good morning, hand. I hope it's a beautiful morning where you are. I think you said at 420 my time, it's around midnight your time, something like that. I think that's maybe what you said. So yes, good morning. It's morning for me too, even though it's like a 11 something. I decided to try and knock the show out a little early today.  And just get out for a minute. Needing some space, I suppose, you know. Feels good. I've been considering a new art project. And it's to take me back to Europe. I'm interested in going to Greece. There's this island they got there, Mykonos. And it's just this very compact group of like white buildings. Almost all of the buildings are white and all the way around the paving of the streets in between the stones is white and everything's beautiful, perfect white. And I think it would be really cool to take a camera and a small portable projector and shoot liquid light videos on those buildings and scenery.  Okay, that's what they've got over there. Now, if you can, imagine what happens if you project a light onto that surface.   And I think that that would be a really interesting photo. And especially down like an alleyway, a small projector that can get down an alley with relative clarity at night.  You sort of like make the dark parts darker. And so I think I could basically make it to where all of the effect that was happening on the dark parts of the rock would essentially disappear. And the colored grout part in between the rock part would be the only part we really see our effect in. And I think that would be an incredible, incredible effect. And I'd love to do a photo series in that particular island. So I'm thinking about finding a week to kind of go over there. And I don't know, man, it will have to be some time when like A, it's moral and legal to go. But also B, it would have to be a time when I could afford it. So see in 2060. But I think that idea is really good. In between then and now I'm going to be doing some smaller projects where I'm going to be doing more of like local shoots like that, finding local municipal buildings and stuff that are their white buildings a lot of times with pillars even sometimes. And I think that would be fun to do liquid light on. So we'll see. If you'd like to fund that project and get prints of all the awesome photos or whatever, I'd love to make that deal with you. Hit me up if you like. Just prattling on about art projects now I guess. But that's just been really on my mind. And I really loved my experience in Europe. I probably talk about it way too much. It's probably the most exciting thing that happened to me last year. And I don't know, just I'm always trying to plan the next thing. I think if you're not planning the next thing, you're not going to do the next thing. Personal opinion. That's based on experience too, you know. Anyhow, anybody ever been to Greece? Seemed nice over there. And do you ever pop up to Greece? I guess it ain't so terrible far from where you're at. I'd be interested in seeing other things in Greece of course.  I'm interested in that. But mostly I'm looking to make art and see beauty and have tasty meals. I think I'll probably start saving up for a projector. That's probably the next thing. Save up for a projector, maybe start shooting these local spots. We'll see. And I shouldn't try it.  It's like a temporary, well I'll only shine a light on it for a few minutes. Probably like 2 a.m. or something when nobody's even around. So, I don't know. Seems fun. If you have any ideas about it, hit me up. I'd be interested to take your opinions. Nice to see everybody today. It's a beautiful day. I know I say that every time on this show, but you know man, in a way it's always true. Anyway, a deep pleasure talking to all of you today. Thank you very much for tuning in. Next episode will be the 50th episode. The 50th time that we've gotten together and smoked out. I think that's very strange. So, maybe we'll try and do something special. If you have any ideas. And let me just hit this off at the pass. Yes, I can get my guitar out. You know, maybe I'll do that.  Maybe I'll do a couple tunes and shout out some artists or whatever. Everybody else in the world is getting their guitar out. I haven't at all. Okay, maybe for the next episode I'll get my guitar out. We'll see. Anyway, I hope you have a beautiful day. I hope that if you enjoy the show for whatever your reason. I hope you feel free to hit me up on my Venmo, man. That's how I've been paying my bills lately. And I appreciate it. So, thank you very much.


Welcome back to my channel guys. It's your girl Coco styles and on this channel. We talk about beauty fashion lifestyle and styling guys So today I have a different lens on so if it looks a little different that is why But today I wanted to talk about fall hats now. I am a fedora girl and I have a million fedora hats. Okay. Um, I actually didn't even bring in my Riding hat. I have a riding hat that I got from H&M Some time ago. I may go grabbing. I don't know but I have all of my Well, not all of them because I have a couple of more fedoras that are from BCVG and The regular fedora hats, but the brim is leather But I'm gonna jump into all of my hats that I will be wearing this fall Most likely with trench coats Somewhat leather jackets Pumps booties over the knee boots all that good stuff So let me jump right into it and the first time I'm actually not gonna put it on and the reason why I'm not gonna put it on is because My hair is too thick for it And these are these are a little bit tighter in size as far as inside Um, this hat is fine. I don't even know how to pronounce his name. I had it for a long time It's a hundred percent wool and it's by a company called yee-stat Y-E-S-T-A-D-T Um Can you guys see that? It's a pretty nice light gray Now I'll say this gray is not my favorite color. However, this is a nice gray It's not like I don't want to say like gel gray color It's really pretty um, but it's a lot more Tight around the head. So I like to wear my hair flat down And it doesn't it doesn't sit like an actual fedora on the head because the way it's like shaped on the inside But it's a lot more I don't know. I guess you could say I don't want to say tight But you definitely can't have like super wild hair with this hair with this hat So this is my first hat and again the company is Y-E-S-T-A-D-T All right, so something like this I would wear I'll try to find Some photos and pop them in with people wearing like gray hats And it has a pretty nice little bow on it nothing too crazy guys and the brim is hard It has like I don't know. It's some sort of wiring in the brim. It's different from the lack of color hats with our The rest of my hats with the exception of one. So that is hat number one Again, I'll pop in a picture of how you can style this Um a gray hat, right? So if you don't like fedora hats, you can definitely go for something You can go for a beret in gray. Um, a scully. Scullies are cute. You can dress those up and down So here's hat number one and Hat number two actually when I'm gonna put these I'm gonna put these Over here on this hat number two and three are From lack of color. You guys know how I feel about lack of color. I love the I Love how they package their hats Actually, I just have one hat in here. I Thought this was the other one. This is my green one This hat, let me tell you Did I wear this yet? No No, so this hat. Oh beautiful green a hunter green You can definitely wear this with neutrals, of course You can throw some red on with this you can probably even throw like a red little feather or something That's cute. I think I might do that for this fall. Um and this hat size is a Medium, I think this is my only medium lack of color hat. I believe I'll double check But this is gorgeous and I actually caught this on sale But I'll find I'll find some I'll pop in some photos of you know different ways. I see people style green hats So just be pictures from like maybe Pinterest or something like that But yeah, pretty green color for the fall This is one of my favorite favorite colors like this and red Neutral colors, I love neutral colors. They just look better on me I do have some colors that are brighter and my wardrobe, but my heart is here with the warm colors So this again, I got this one sale this one on sale now You guys know lack of color does have sales occasionally so my recommendation would be to Create a shopping list use the karma app that I've spoken about before use the karma app and Start creating a list when the stuff starts to go on sale When the stuff starts to go on sale you'll get notified about the sales that are going on And I'm gonna actually touch on These two hats I did a video Comparing the colors of these two hats, but I'll link that Over here. It's this lack of color hat that they call ivory But it's not really ivory you can't really see it on camera It has like a yellowish tint to it but still a very nice hat and this I got in a large And I remember I got a large because I wanted them to sit a certain way On me And the large was better because sometimes I'll wear like a unit That's like kinky and you guys know it's much thicker than something that is a lot straighter So this I'm looking in America. This is gorgeous I cannot wait until the fall like really really hit so I can get busy because you guys know where these hats in the Spring is just a no-go because your head is going to be sweating So beautiful hat, right? You can't really see the color guys because I Don't know this. Let me see if I can move my light over a little bit. Let's try this It's still kind of bright, but it has like a I don't know it still has the boat on it Like I said, I have my other lens in so it may not get the same effect as my other lens But this is a large so if you want to wear Hats like this if you are a girl or a lady a woman who wears units Maybe big curls and stuff like that. Definitely go for The large if it's too big you can always get the hat filler and put put it inside To kind of make it fit a little bit tighter I'm gonna actually skip over the other two lack of colors from that and go into the bricks and hat Um This is an actual ivory color hat guys, this is pure ivory What that is is something else. However, I'm still gonna rock it of course. So the bricks and hat It's nice to it's not as a big as the lack of color hat But it's still a gorgeous hat. You guys know my issue with bricks then is their Shipping, okay They're shipping snow bueno, so this was another hat that I purchased and the other hat that got ruined not to straw hats Another wool hat that was the last wool hat I purchased from them I'm not sent it back because it literally was like Mashed and they only shipped it with that little plastic piece over it and basically what happened was UPS Destroyed it like totally smashed into the point where I couldn't get that plastic piece off But this is an actual and this is a medium So these fit a little bit different from the lack of color has but if you want to guys This unit so big if you want to get something Bigger just always go for a large and just find the hat fillers and I'll show you on the inside The little space you guys know how hats are a little space you can just put a hat filler in there and this one Has like the Velcro where you can just like kind of like tie it in there or whatever But this is my other full hat So it's gonna be a lot of nice jackets and hats for me this fall I'm miss the hat season and the jacket season and that's cuz I am a New Yorker guys, so I Love hats And then these last two here are I hope this camera looks good. So these last two are lack of color I said I love lack of color right and this is more of a Now here's the thing the light of color Some people may not wear in the fall. I still works. I like light colors But they may prefer this one and I got this one in a large as well You guys not been had these these are not new hats. None of these are new Make sure yeah, none of these are new. I had them already And this is I forget which color this is I can find the color I can try to find the color, but I don't pop in a photo of somebody styling some these sort of color hats With jackets, I'll do it with jackets, right? And this is a large also you guys can tell that if it falls it fits on me different and I love it. It's a pretty pretty amazing color I'm just sitting here. These pants are like digging into my belly guys So, yes. Yes. Yes. Yes. What do you guys think? I love it.  We can't change that right?  They've been on my list for like a good Year and a half guys. The problem is I don't want to pay that customs fee But if I do I'm gonna get multiple hats um and add it on to my other my other Hat that I have in the room, which is a like I said it's a like a riding hat that hat is leather It is super super super cute Okay, so for this fall, I'm definitely going to be wearing a lot of my Fedora hats, okay and I'm gonna get me a few more. I have a whole bunch of Braids, but I don't know if I'm going to do the regular ones this fall I may do something similar, but just have a little little bag to it, right? So those are my hats for this fall all of my Fedora hats that I'm going to be wearing this fall with trench coats You know button-ups because it starts to get chilly fall is one of those times where it's cold It's chilly, but it's not like freezing Depending on where you are because sometimes New York can get like extremely cold so That is one two three four five six that six hats that I have That I'm definitely going to be rocking this fall because that's what I'm going to do and Other accessories that I'm going to end up getting I have a few pair, but I'm still looking for a nice pair of red leather gloves I need two pair guys I need a regular pair and I want a pair that comes up to my elbows if I cannot find them I am going to get them made. Okay. I've been oh thunder I've been wanting those for a long time. So Definitely going to be looking into that getting that soon And of course, I'll show you guys so those are my hats for this fall Let me know what kind of hats you're going to be wearing this fall.

Welcome to Stand the Energy Man on another beautiful day in Honolulu. In fact, today is so beautiful, it's a holiday. I went surfing this morning for the first time in a long time and it feels really, really good. So anyway, welcome to Stand the Energy Man. I'm Stan Osterman from the Hawaii Center for Advanced Transportation Technologies. We're going to start off today with an email that I got from a friend on the Big Island. Introducing me to some videos from the University of Minnesota professor, Dr. Nate Huggins. I'm going to try and get him on my show sometime soon. I don't know when, but it can't be soon enough. I watched these videos several times and I'll try to take his beautiful analysis of the connection between energy and economics and present them to you today. But you really should look at his videos and they're going to be posted on the site there. You can actually pull them down from the ThinkTech site when you go and look at the show here. He says that we are all energy blind and he's very, very correct. He makes the point that economic economists don't have the energy in any of their models, but he notes that there is a very close correlation between things like GDP and other critical economic data points and energy. He tells you why and I'm going to try and, with some help today, tell you why also. For example, in Congress, there's much talk about the Green New Deal and some call it brilliant and some call it kind of BS. I hate to sound wishy-washy, but it's actually both. There's some changes on the horizon that we can plan for and we can plan for or ignore them. That's the decline of cheap fossil fuel. AOC has reacted in the frame of climate change, but at least she's got the part about burning fossil fuels right. It's not a matter of CO2 causing the world to heat up. It's not even a question of if we'll run out of fossil fuels, which is a scary thing for many industries today. But more a matter of when will it become too expensive to buy fossil fuels? Think of all the products made from oil. It's simply supply and demand. Right now we're just burning it because it's like burning monopoly money. It's cheap, it's easy. Right now we have no other choices of energy other than fossil fuels. They're cheap and they're plentiful. We take the energy for granted. But when oil starts to hit $150 a barrel or more, and gas and diesel are up in excess of $20 a gallon, every single product and service on the global economy will feel the impact. And if we don't have alternatives, we're simply screwed. But are we going to give up travel? As my favorite Hawaiian senator said recently to our colleague, so how will I get from my home state to Washington D.C.? Apparently Congresswoman Cortez missed the geographic point that the 50th state in the U.S. has a 2500 mile moat built around it, and if ships and airplanes aren't on the table, Hawaii has some huge issues to address, like who's going to stay in Waikiki? And how will I get my toilet paper? So the good side of the Green New Deal is that we need to face the reality that fossil fuels are too valuable to be burning for energy for very much longer. But the bad part is that if you don't understand the economic connection between energy and economics and what it takes to get by today, you can really dork things up. We need a strategic plan, a transition to the future. An energy future that has fossil fuels off the table and trying to transition them is unrealistic. An unrealistic timeline is just not going to work. This means not letting the price points drive decisions for short-term gain. So here's some of the links to the shows, and we'll put them on the website, but bottom line is when I go to conferences and I talk about hydrogen and what it means to use hydrogen to store energy, a lot of people go, oh, it's too expensive and we can't do it right now because it doesn't compete with fossil fuels. Well, the question is, are we going to wait for the price point so fossil fuels are more expensive than hydrogen before we start trying to replace over 100 years of electrical infrastructure and fossil fuel infrastructure to make that change? The answer is I hope not, because I don't think our world economy can handle a shock. Anyway, on today's show we'll talk about this with Mr. Ryan Wibbins, my favorite electrical engineer from Burns and McDonald, and Ryan, welcome to the show again. What do you think about that? Yeah, it's very important to look ahead if you're going to have a deep-eating resource in the future on how you're going to replace that. When we talk about it from an energy standpoint, we understand that to replace a generation source we have to make something else. That's easy, but it costs energy to replace it. So just saying that we're going to replace our current generation because maybe the price at this point is getting too high, we are losing the amount of resource we have, so demand is staying high, but supply is going down, that price gap will start to drive up the cost of energy. Well, now we have expensive energy. We need to start replacing it. Well, to make the new stuff it's going to cost more energy to make the new resource, a solar panel costs energy to make. The cost of energy, when you think about it from an economical standpoint, there is this return on investment, there's this return on energy that you get when you make something. When we're using oil in the early days, put your finger in the ground, it was like oil is just squirting out. As we know, that will get harder over time. When that exact point is going to happen is obviously debated by many different people. I don't really, I think everyone is saying, yeah, that eventually you could use it all by night amount. When we think about energy from a return on energy that you get, think about it like there's a dollar on the ground picking up that dollar is very easy. You'll do that. There's even sometimes there's these calculations with multi-billionaire people like Jeff Bezos or something. If you saw a $20 bill on the ground, it's not worth this time. I've got other stuff I can do to make more than $20. So for us, because I don't make billions or that kind of money, what if it's a quarter, a penny, you'll have a penny. You've got to bend down and try 100 times to pick up that penny. Are you going to do it? At some point, you're going to say, no, that's not worth my time. Energy is the same way. Right now you go into the ground and you pull something out. The return on energy investment is something like 100 fold for oil, natural gas. That can decrease. If you go into different environments, something like Canada, it's a much lower threshold. You don't have the energy to get the energy out of the ground. It's still worth your time right now. That metric will change. Different technologies can help you out and help get you back to making it easier to go down and get that quarter or to get that dollar. I don't have to go 100 times to get that penny, but eventually in theory, yeah, it'll become very difficult. Right now the US is kind of focusing on our own internal sources of natural gas and oil. We're actually kind of putting the kibosh on coal a little bit. We have these resources available right now and everybody thinks we'll not run out of them. But when you look at how the future is shaping, the future is going to be electric transportation. Cars are going to start becoming electrified instead of fossil fuel. And you have this dynamic, and this is where this title of show comes from, equals not equivalent. You know, energy is, your first law of thermodynamics is like, you can have energy in all different forms. It never goes away, it just changes form. But you can't eat money. And you can't put dollar bills in a fuel tank in a gas engine and make it run. And you can't, you know, the different ways you have economic inputs and energy into a system matter. But right now we're pretty much so focused on fossil fuels that we don't have that replacement. And as you mentioned, not only does the infrastructure get expensive as the price of your fossil fuel gets higher and higher and you're trying to bring in the new technology, but think of all the other associated industries. You know, we used to have thousands of people working a few acres of land to grow a crop. Now you have six people working a thousand acres of land and they have big combines and big equipment and they can do it. A family can run a thousand acre farm in the Midwest and make money on it and get it going. That's five people. Well, big cities would starve to death if a bunch of those farmers couldn't farm for a couple weeks because they didn't have oil or couldn't run their equipment.  Well, if airline prices go up higher and higher and air freight prices go up pretty soon, the cost of freight to ship your stuff is going to be, like here in Hawaii it already is, more expensive than what you're buying. I've ordered some $30 worth of stuff and it cost me $30 to ship it. In fact, just last week I sent two envelopes to the mainland and Express and it cost me $33 for one and $29 for the other one. And it was two envelopes, I mean, two legal size envelopes. It's like, there is so much economically tied to the cost of fuel today and that insidious price rise is kind of blinding us to a potential disaster because the U.S. is doing well right now. We have a lot of our own resources in Alaska, on the Conus, in from Canada, but we take them for granted. What if something happens where they're not available? Then what? And even just the incremental increase, are we going to wait until hydrogen is so much cheaper than fossil fuel that we start infrastructure? Then your formula kicks in where the infrastructure gets more and more expensive to replace it. You may never catch up and the economic impact can be huge. Yeah, it can be huge.  We've experienced in our own history that when we lose these lack of energy resources being imported, the amount of impact that it can have on our own economy. Looking back internal, that's one way to buffer yourself from that, but then just because there's not a political reason or a physical reason that it can still come out of the ground, there are different ways natural disasters being one that we can be cut off from our own supply very quickly. And that imbalance is what would start to cause the problem. Yeah, and a true crisis will make you react. I mean, it definitely will. Nowadays, the big crisis is climate change. So I pulled this off the internet two days ago. American energy surges despite climate change concerns. What was that one more time? Energy. American energy use surges despite climate change concerns. Yeah. Right off the internet. I mean, with everybody talking climate change, with all the angst that President Trump got for pulling out of the Paris Accords, with all of the politicians jumping on and saying, we're going to tackle this ourselves, we're still using more energy. And like I said with transportation, with 5G coming on board, electricity is going to be more required in our grid, in our system to charge vehicles to take care of a new technology that comes on board. So we're adding to the energy requirement. We're trying to transition to also free solar wind and things like that. And we're going to try to absorb the entire transportation sector and agriculture sector and everything else that uses fossil fuels. We can't be waiting, you know. We don't need a crisis to hit us between the eyes. The economy should be picking up on this trend and letting stock market and investors realize that we need to make this investment now to make it so that we have a stable market, things keep going about the way they do. We're not reacting to a real crisis like boom, all of a sudden Middle East gets in such a big turmoil that none of that oil is leaving anywhere because all the infrastructure is gone and the whole world is fighting for American oil or natural gas and the price starts driving up. Sure. So I had a very quick point I was going to make. We love consuming energy. Everything new that comes to us is a great way for us to consume more energy. Cell phones we just draw the line of one much energy a cell phone draws. It's very little power. Plugging it into the wall for 30 minutes and it's charged up all day if you got a phone a lot better than mine. I'm more of a half day kind of guy. That's a little bit of energy. But now what are you doing with that? You're on the internet more. You're taking pictures and now all of our pictures are stored. All of the emails being passed all of this computing power is happening at large data centers or these cloud based computing places. These are energy monsters. Now the people putting these in are becoming very aware and wanting to build a renewable infrastructure around them. But that cell phone those pictures you're taking the emails you're sending that's where the energy is being consumed by the computing power somewhere else. Not just the little wall socket. And not just the computing power but to keep our equipment cool because you can't let it get hot or it shuts down. We're going to take a quick break here and we'll be back in 60 seconds to talk a little bit more with Ryan Wibman. Hello, hi, and Mabuhay. My name is Emmy Ortega Anderson inviting you to join us every Tuesday here on Pinoy Power Hawaii with Think Tech Hawaii. We come to your home at 12 noon every Tuesday. We invite you to listen for our mission of empowerment. We aim to enrich, enlighten, educate, entertain, and we hope to empower. Again, Maraming, Salamat Po, Mabuhay, and Aloha. Aloha, I'm Lauren Pair a host here at Think Tech Hawaii a digital media company serving the people of Hawaii. We provide a video platform for citizen journalists to raise public awareness in Hawaii. We are a Hawaii non-profit that depends on the generosity of its supporters to keep on going. We'd be grateful if you'd go to ThinkTechHawaii.com and make a donation to support us now. Thanks so much. Hey, welcome back to Stand on the Energy Man on a beautiful Friday here in Hawaii. Not on my lunch hour today, and let's pick up kind of where we left off. I used to do this actually two weeks ago. I talked a little bit about this because I was still watching those videos from my professor Hagen's. He had a slide in there. By the way, he's kind of a farmer. He grows his own food and has his own property and stuff. He's pretty self-sufficient. He had a picture of himself with a Dutch boy haircut and shorts and white legs and shoes and socks kind of comical. He had a little one-tenth over his head and behind him is his draft horse that he uses, he says, when he can get him to move to do some of the work around the farm. So that horse represents one horsepower and he represents one-tenth of one horsepower.  That's 45 horsepower and then he had his truck which I thought had more horsepower but it's a diesel truck and has 150 horsepower. And he points out that, you know, back 200, 300 years ago all we had was pretty much manual labor and animal labor. So we're talking one horsepower or less until you multiplied out the number of animals or people that you had working. And that's the maximum amount of energy you could get applied towards any kind of work moving, putting in fence posts, moving rocks, moving trailers or carts or things. Just moving, moving yourself from point to point. But as the industrial age kicked in, now we had gasoline-powered or coal-powered steam engines for like locomotives and trains and vehicles that all have this enormous amount of extra power, the ability to do a lot more work in a shorter period of time, which is, if you take the definition of horsepower, it's a factor of amount of energy you have and amount of time that you applied to doing work. You can get a lot more work done in a shorter time with a lot more horsepower. Well, what I didn't notice on that same slide, later on he actually adds an airplane and that's 100,000 horsepower. He says, next time you're flying across the US down at all the nice scenery, just realize that the energy it's taking to get you from point to point is massive and you should be appreciating it and not just bitching about the price of the ticket because it's actually a lot of energy going into making that pretty much marvelous thing that the Wright brothers started off with 100 years ago into what it is today with four or 500 mile an hour transportation. So, when it comes to other modes of transportation we talked a little bit offline about boats and I sent you an article that I got about some folks trying to look at electric ships and you had some comments on that. Yeah, when we talk energy and amount of energy it takes to move to tie into our first half we're saying that we love consuming energy but right now we have this deep and high return on investment type of energy so we are able to do things just amazing. When we want to look at what it would take to convert off of that we started talking about a ship and an electric boat we get to a very large vessel a containerized vessel so I had an article that I love because I like talking numbers and we were talking about a little bit back and forth about the amount of energy actually consumed on a boat in a diesel tank and then comparing that to what it would be in our current battery format and seeing how those two compare so do you have some of the numbers you can share a little bit? Yeah, actually this article it has and it's pretty concise here so they're describing the current container ship that they call the OOCL, Hong Kong holds a record 21,413 40 foot containers and it cruises at the super slow gaming rate of 16 knots that's a fuel savings rate these ships can make their journey from Hong Kong to Hamburg, Germany in 31 days so now they look at a brand new ship called the Yara Birkland it can carry 120 of those containers at a speed of 6 knots and as far as it can go is 30 nautical miles and it will carry let me see batteries it carries are 7 to 9 megawatt hours worth of energy stored and the other ship just by comparison can carry 150 times the number of cargo containers a distance of 400 times farther at a speed of over twice as fast but the weight penalty weight you can't possibly put that many batteries on a ship to move those distances and those speeds without taking all the other containers off but at a certain point all you're doing is driving a ship full of batteries and not a whole lot of cargo so that gives you a good visual feel for how much density there is in the fossil fuels we use today that we take for granted it's incredibly energy rich and that's what's done so well for us 100 years is the easy return I'm going to grab something and use it and we're still in that time right now so we're looking at a ship that would take 150 times less cargo and an absolute magnitude higher on the energy consumption so we get into this problem we want to switch but how are we going to do that with the diesel and batteries that we've been using your double A's, triple A's even in some of the cars being used now if you really want to get to what I would say the larger use batteries they have their use even on the grid we have some use for batteries but it's not it's not our magic bullet I mean this is some quick math and even if you put in a learning curve on how much better can we get the theoretical limit on how much better we're going to get and we're not too far off of what that will be that's chemistry and science in the way there so it's not that for that application we need energy dense in this case energy dense transportable fuel that's what's made the ship move right now the other part that it is is the cost aspect we know that that's going to shift in the future this is a look the battery is not going to be the energy medium for high energy dense transportable fuel the math is not there we said hydrogen hydrogen is close if not more energy dense than diesel it so it's you have a model that can be proven just by energy now it's a matter of being prepared for the economics to shift and that's where they're not there right now we're picking up orders $20 bills off the ground right now not penny what is going to make that shift hopefully it's not a crisis hopefully it's something a little bit more planned that will allow that change to take place but I think for hydrogen's goal you can take incremental steps to get there right now I think reformation with natural gas making hydrogen is a very logical first step keep the price down for now and use a resource we're used to and it's still cleaner than burning fossil fuel even though it's a fossil fuel they're starting with it's easier to sequester the carbon from that process and things like that maybe use that carbon for carbon fiber and other things nano structures there's some things happening right now I just talked to a friend of mine who makes electrolyzers and he says they've gotten the cost of manufacturing hydrogen from water and DC power down to about $10 a kilogram $10 a kilogram that's around $5 a gallon between $4 and $5 a gallon well we're not real far from that right now and the price of gas creeping up over the summer could easily hit those kind of mark so even if you talk about price point we're right there already that's probably a good signal that we could start doing this another thing is we could look at hybrid vehicles and focus on them we could also look at hydrogen in internal combustion engines now there's some tricks to doing that and I've actually worked with some folks on doing that and it's not easy, most of the folks that try and use hydrogen in internal combustion engines run into hydrogen is energy dense by weight but not by volume so when you try and push enough hydrogen into a cylinder to give you the bang for the buck it's really hard to do but there are ways to do it you have to change the dynamic in the engine, in other words change the timing you have to inject the hydrogen under pressure or under stroke, detonate it in a stratified mixture and make the engine work and there's people doing that with diesel engines that actually get better performance out of the diesel engine with hydrogen and with diesel so with all the internal combustion engines in the world today there's a couple ways we could start transitioning to hydrogen internal combustion engines converting them to hybrid and you go straight to fuel cells but they all involve hydrogen so we ought to start looking at that yeah, that's very realistic that's pretty neat combustion engines drive just about everything right now so the opportunities are everywhere well that's good to do it for this week in Stanley Energy Man thanks again to Ryan for being here on the show and we'll see you next week, Allah


Good morning, everyone. Welcome, great to be back at Yorah Python. This is my talk, Physical Computing with Python and the Raspberry Pi. My name is Ben Nussle. I'm from the Raspberry Pi Foundation. We've got a series of talks today, so we've just had Karyan's brilliant keynote, and we've got a few talks lined up in this track related to education. It's the Education Summit that expands to this weekend as well. We've got some sprints and education stuff trying to crack on with Karyan's list that she's given us all to do. So a bit about me to start. I'm an education developer advocate at the Raspberry Pi Foundation. I do software and projects, kind of develop stuff internally, and do some, I write learning resources that go on our website, the free and Creative Commons learning platform we have there. We run teacher training courses with something called Pi Academy, and I do a lot of outreach, go to a lot of conferences and stuff. We're based in Cambridge in the UK. That's me on Twitter, Ben Nussle. If you were at EuroPython, Pycon UK, PIS, Pycon Island, or EurosidePy last year, you may have seen me speak. So just a quick update. Since I was here last year, the news is it relates to hardware. We've now got the Raspberry Pi 2, second-generation Raspberry Pi. It's now a 900 MHz quad-core on V7 with a gig of RAM. Its back was compatible in exactly the same shape and size as the previous model, the B-plus. We kept it at the same price, which is $35, and reduced the old ones down to 25, and the A-plus is 20. So we are an educational charity, as Cary Ann's just been talking about. It's not something that kind of came afterwards and kind of bolted onto a computer company or a hardware company. The idea was originally to help education, and that's why we wanted to create something to empower young people and give them a possibility to learn programming skills and learn about computing from an early age in a kind of sandbox environment. They've been on general sale since 2012, and they've been made available worldwide to everybody who wants one for the same price. We're not limiting this to just children or just the developing world. It's the same price for everyone because that's really helpful to have that whole community around the Raspberry Pi. I'll give some examples. We write free learning resources for makers and educators, and as I say, we have this Pi Academy, our teacher training CPD course, professional development course currently in the UK. We run a few around the UK, and we're taking it to the USA next year, and we'd like to see more things like that around the world. A couple of stories to start about our community and about our origins and how things have developed over the last three years. Ben Crossden is a guy in the UK who brews beer. He wanted to use the Raspberry Pi to control the beer brewing process and monitor it from his phone and have a web app running in that kind of thing. He chose the Raspberry Pi and chose Python to write it in, so he started to develop a platform which allowed him to communicate over the GPIO pins. I'll explain more about those in the next few slides. That project became a general-purpose library for how you talk to the GPIO pins from Python. Another example, Dave Jones, also in the UK. His wife is a paleontologist, and she wanted to use a microscope to do some fossil photography and that kind of thing. The problem was that the university's microscope was a real pullover to use, and it stored it to an external drive somewhere else on the network that you had to then get permission to access, and it was a real pain. He said, just stick a Pi camera on the top, and then you'll get the pictures straight out and be able to use them. He built a little web app that allowed her to monitor and deal with all the pictures that came out of it and archive them. Again, this became the general-purpose Pi camera library, and it's a fantastic resource for people to anyone who wants to use the camera for anything, and he's been working on it ever since. In fact, I told him recently, because I kind of talk about this in a lot of my talks, and I said, oh, by the way, I always use you as an example of when I'm talking about community at the conferences, about how you created the web app for your wife, and he said, oh, did I? Is that why I started? So Raspbian is our Linux distribution that we use. It's a foundation-issued, Debian-based distribution, currently based on Debian Weezy. Jesse is now kind of stable, so we're going to be moving to that shortly. The image that we provide supports Pi 2 and Pi 1, even though they're different architectures on 6 and 7, but we make sure that we still support our old users on the old platform. We pre-install certain software on that image, so you get the Python interpreter, you get idle, unfortunately, and a bunch of other stuff. There's Ruby on there, Sonic Pi, Java, Mathematica, and stuff like that, that we kind of put in the image and create it so that you can use it out of the box. We have other things as well that are kind of community-contributed, so the GPIO library and the Pi Camera Library, for instance, are examples of what's already installed and once we move on to Jesse, it will be a lot easier for us to ship with pip pre-installed. There's alternative distributions available, so Ubuntu, now we're on ARM V7, also works, and there are other ones like Arch Linux, but we support Raspbian ourselves and maintain that ourselves, and all for educational and general-purpose use, we recommend Raspbian. You can get that from raspberrypi.org. The GPIO pins, so this bank along the top there, we refer to as the GPIO bank. Now, strictly speaking, they're not all general-purpose, so they're called GPIO, general-purpose input-output. Strictly speaking, they're not all general-purpose, so you can see this little accessory somebody made. Our community's full of cool stuff like this that people create and put on sale and there's whole businesses around this, but this is a little pin diagram that you just stick over the top of the pins there to tell you which pin is which. So you can see here there's some 3-volt pins and some 5-volt pins, some ground pins, and then these ones are GP and they have numbers. So the GP-19 is general-purpose pin 19, and those ones you can control. You can have inputs or outputs listening for inputs or sending outputs. You can wire things up to those to do physical computing. Analog, so there's no native analog pins on there. They're all digital pins, so ones and zeros, but there are options if you want to use analog inputs with Raspberry Pi, so you can use an ADC to convert analog into digital. There's various Arduino-compatible add-on boards available and there's also PiSiri or the Python module for reading Arduino pins over USB. So let's have a look at the R-Pi GPIO library. So this is included in Raspbian and the implementation is in C. Features are you configure pins, so you give a pin number and you define that pin to be an input or an output, and then you can change them in your script. You can read the inputs, so you can say, is this one high or low? You can just get the value of it, and you can send outputs, say, turn this pin on if it's an output pin. There's also a feature called wait for edge, so an edge is when something changes from high to low or low to high, and you can have a script that pauses and waits for something to change, like wait for the button to be pressed and then continue, and there's event detection with callbacks, so you can run a function on the event of something happening, like a sensor going off or a button being pressed. This is kind of fundamental to everything you might need in such a program. So just a quick example. We've got some stuff on the breadboard here. We have a circuit connecting, putting three volts through an LED and through a resistor to limit the current. Then we have it going back to ground, so that just completes the circuit. There's lots of little bits of basic electronics that kind of help you with these sorts of projects. I don't know an awful lot about this, but just enough to get by. This is just a complete circuit with an LED in it, and putting three volts through there that gets limited through the resistor just means that this is always on. I can't change this in my program. It's just connected to always be on, because it's sending three volts through.  This is what the code would look like. We import the GPIO library. We set the mode, because annoyingly there are two numbering systems for the pins, because one isn't enough. We set the mode to BCM, which is the actual numbers that they are according to the chip, so the GP2, GP3, GP4. We set the mode, tell it which mode we're using. I'm using a variable here just to say which pin represents the LED. I set up that pin as an output, and then here's just a little bit that just goes turn it on, sleep, turn it off, sleep, in a loop. So that's just flashing the LED on and off. This is really empowering, especially for young people or for anyone. Instead of just having something saying print hello world or fry in range 10, print I, this is something flashing, something in the real world, something physical. This is another example. A simple circuit where we've got a button going from GPIO 17 through to ground. So just complete a circuit there. We can listen on pin 17 and wait for that button press. So this is what the code would look like. In this case, I'm actually using the pie camera library, so the button is going to trigger the camera to take a picture. So this is just the setup. So we have our set mode, button is pin 17. Setup pin 17 as an input. This is the pull, this is, that's wrong actually, that should be pull up or down. So we set it up, we tell it which pin, what it's going to be, and then here should be GPIO pull up or pull down. This is an electronics, bit of an electronics which determines whether a floating value, like a digital input, is you kind of send it to high or low and then you wait for it to fall. If you've pulled it up, that means it's been pressed. And if you've pulled it down, you wait for it to rise. This is a mistake. So here we, and then the following on, so that's our setup, and following on we have with the camera, so with an instance of a camera, pie camera object, we start the preview of the camera sees in real time. Then we have a loop which just says wait for that button to be pressed, wait for that to fall. So I would have pulled it up on the previous slide. And then it just sits and waits for that button to be pressed on 17, remember this is 17. Wait for that button to be pressed and then continue. So it would go onto this line and capture a frame. Then it is right around incrementing the frame number to this bit here. And then, this is pointless because it's a while tree, but you could have something to catch that to exit like a second button or just a keyboard interrupt. Another example here, we've got this is for a GPIO music box. So instead of wiring up just one button we wire up two. So we have two buttons. We've got one going to GPIO 2, one going to GPIO 3. Then I create an add, use add event detect on that button looking for a falling edge because I've pulled it up. The callback is the function I've defined as play and the bounce time, which means how long it takes before it lets another event come in. A thousand milliseconds, so one second. So I would have a function here called play, which I've defined as my callback. And then all I'm doing here is saying when this is called and it passes in the pin number that actually triggered the event into the function I look up which pin in here and I get this is a pygame sound object and then I can just go sound up play. So I know which pin was pressed, two or three according to which one. So I would do this on both buttons. Then look up which sound to play and play it. This is a really simple straightforward example of using events for multiple button presses and doing different things according to different inputs. There's something great for these types of projects which are really kind of small and simple but really empowering and really can be really interesting and engaging. They're called the Cam Jam Kit. They're just a collection of little bits, really useful bits for lots of these types of projects. These are light and resistors and wires. This is Kit 2 which has a load of sensors. It's got a passive infrared sensor so you can use that as a motion detector. It's got some LEDs, a buzzer and some other bits in the breadboard. These are really cheap. These cost five pounds and this one costs five pounds and this one costs seven pounds. It's a really pocket money electronics. They come with a bunch of things that you can follow along and these are just put together by one of these Raspberry Jam, the community events, in partnership with one of the Raspberry Pi community resellers and accessory sellers. They just got together and made this really cheap and tried to put it out there for more people to get involved in this sort of thing. Once the Raspberry Pi came out there was a lot of add-on boards and accessories and one of the first ones, one of the early ones by a guy called Goertz. He's actually one of the chip architects at the company that made the chip that we use. He's very knowledgeable about Raspberry Pi and here's him teaching me to solder while I'm wearing an elf hat. He made this board called the Goertz board which is, you know, he's an engineer and he thinks this is exactly what people need. This is an amazing board that gives you loads more potential to get out of your Raspberry Pi. It's got all this stuff on it and you know, technically he was right that it's a really cool board and it can potentially do all these things but he didn't provide any software for it and he probably just put, you know, here's a C program which, you know, you can use for this mini project. And another barrier to this was that initially it came unsoldered. So you would buy a kit like that and you'd have to solder up all of that entire board and then there was no software so a lot of people kind of get turned off by that sort of thing because they want to get going. So I'm going to go progressively through kind of good examples. So this one is a young lad actually he was about 17 when he created this called Ryan. He created a little lad on board that just does one thing really well. It's just a little motor controller board. So you can drive motors so you can use it in robotics. He didn't provide any software for this but he, no bespoke software but he shows you how you can use the GPIO library to drive the pins forward. So you can, as long as you know which pin is which, so which pin it's connected to, we'll just say pin 17 is the left motor forward or pin 18 is the right motor back. Then you've got enough to go with and you just write a little bit of code similar to the examples I showed you earlier just turning pins off for a certain amount of time and it will drive forward or spin around or whatever it is that you've asked it to do. So that's kind of cool and a nice nice learning, nice not too steep learning curve. This is another example which is kind of further along the spectrum.  They provide a software library for this. So import Piperella you've got a full abstraction away from which GPIO pins things are connected to you just refer to them by the light and the color. So you just run this function Piperella.light.green.on the green light comes on instead of GPIO output 17 true you have turned the green light on. There's a really nice abstraction especially for young children to get involved even less of a steep learning curve. There's plenty you can do with this as well they've even got event detection so you can create a function that flashes it so turn it on for one second so this is actually all the lights because I didn't specify a color sleep for one second then turn them off and then I can say when the button is pressed run that function so when I press the button flash the lights all the lights on for one second and there's loads of places you can take this this is an add-on board called Energini it's a company that makes remote control switches so you can buy a remote you can turn off the Christmas tree lights without having to get right behind it then they made a Raspberry Pi add-on board so this just sits on top and they provided you a massive file with about 50 lines of Python saying this is how you turn switches on and off we had a young girl with us on work experience she was about 15 we said can you take a look at this code kind of tidy it up work out the logic and then put it into a function that you can turn them on and turn them off because 14 or 15 year old girls are better at programming than the people who make this thing and then I packaged it and took all the credit and put it on on pip so you import Energini switch on and switch off you can pass in the number of if you've got a bank of four one two three four you can turn on the sockets arbitrarily with numbers I also made a little web app to show that you can do this sort of thing this is just a little basic flash app which is on the documentation you just press that on your phone to turn them on or turn them off that was running on a local network configured your router correctly you can do that over the internet and there's plenty of services to help you do that as well so a bit over a year ago we moved from the original Raspberry Pi this one the original Raspberry Pi model B to the B plus so this was still Raspberry Pi 1 but it was a plus version and we extended the pins from a 26 pin to 40 pin so you get a lot more to play with and the hardware would sit on the 26 pin bank and they still work because the first 26 pins are exactly the same but we also defined a specification for add-on boards people don't have to follow this they can still make 26 pin ones they can still make 40 pin ones not following the rules but we call these hats so it's hardware attached on top of the official specification for add-on boards it has features such as you can use ribbon cables like this if you put it out and if you put it in exactly the right dimensions it will fit nicely on top of a B plus or an A plus or a Raspberry Pi 2 and you can use mounting holes because we've used the mounting holes with screws to just hold it in place one of the projects we worked on last year was looking at sous vide cooking for back-impact food such as steak like this and you cook it in water at a very precise temperature so we decided to design some hardware to do this, we did some prototyping first with breadboards and stuff and then we had somebody create an actual hat for this so if it's a hat for cooking it's called the chef hat so it was like this we used the Energenie to remotely control the cooker, it's kind of dumb really we're using a temperature sensor in the water and if it's too high if the temperature is too high we turn it on, too low we turn it on otherwise we turn it off there's a little library that I'm working on it's a work in progress we have another board called these are just some kind of internal projects that we've been working on there's one called the dots board which uses conductive paint and there's a load of little holes on this board that you use with a paintbrush to draw a pattern from to connect the dots we tried this out at a couple of events we went to make a fair and got really young children engaged in doing something more interesting than just typing on screen so they sit there for 5 or 10 minutes just drawing out their plane really intricately they take it over to the Raspberry Pi stick it on top and then they run a Python program that draws a plane in the colours that they chose along the top which is kind of a really novel idea and this is some of the part of the software and all we do here is so we have a pin is active function so we just check given the list of pins we know to be the error plane pins we just count how many of them are active and not so just by putting paint over them connects the outside of the dot to the inside which shorts at the ground which you can detect in software and then we just have how many of them are connected and if enough of them are connected we show the plane it was a little pie game pie game app another one the plant pot greenhouse so this is a beautiful looking board designed by Rachel Reigns from Raspberry Pi Foundation and it's a so this bit you kind of clip all of these bits out so this bit sits on top of the pie that's kind of hat like and then you have a wire running to the sensor board which is this stick here you stick that in soil it's got a soil moisture sensor a light sensor and temperature and humidity and you just use it to monitor the conditions of the plant the you put it inside a little acrylic kind of greenhouse thing so the pie is inside there and then it LEDs on top of the board glow according to the whatever you programmed it to do according to the whether it needs watering or something like that this is one made by an amazing American company called Adafruit the capacitive touch hat so you stick this on top of the pie and you wire up crocodile clips to each of the pins to each of the holes on there and then you can this bit like makey makey where you can build a piano with fruit or something like that you wire up that up to anything and then in Python just read which ones have been pressed and then have different actions according to that there's a bunch of really cool hats made by the community and made by these companies that have accessories Pi Moroni is a brilliant example they were one half of the team that built the Pi Brella that I mentioned earlier this is the unicorn hat so it's a nice 8x8 Neopixel grid that you can program really simply the sky writer which is you can hover your hand over it and it will assign different events to gestures or how close you are and things like that the propeller hat which is a little prototyping board and the explorer hat which has got a lot of capacitive touch things along the side and sub lights here and you can control motors from these extra pins you have here really easily and this sort of thing is really helpful to put out there because it means a teacher can pick that up and really simply put together a simple robot or anything that uses motors or capacitive touch and the great thing about Pi Moroni is that they provide the software libraries in Python and always in Python 3 unfortunately we always nag them about this but it's great that we can have this sort of thing readily available we have something another internal project we've made this weather station so it's a board that sits on the Pi that has some stuff going off to some other sensors we've produced this in-house and having it manufactured and we're sending a thousand of them to schools around the world to collect weather data and feed into a big database that's going to be really cool James Robinson my colleague is going to be giving a talk about that later on today so again this was prototyped on a breadboard just components and looking at different sensors and then some software running that just reads the sensors logs it, uses database that kind of thing we have a, this is kind of our headline project of the year AstroPi if you haven't heard of it is that we're sending two Raspberry Pi's to the International Space Station at the end of this year British astronaut Tim Peake is going to be going up in December and he's taking these two Raspberry Pi's with him he's going to be doing some educational outreach as part of his six months in space so there's some kind of general education stuff they're sending some rocket seeds into space and bringing them back and then distributing them to schools for them to experiment with and growing the seeds to see if to compare seeds that have been in space with regular seeds that haven't been in space to see if there's any difference in their growth and for them to start thinking about space more and another program is this AstroPi competition which is we've built this sensor board which sits a hat that goes on the Pi and there's a competition for kids to write code for this sensor board that they will pick the winners and run that code in space so primary school and secondary school kids in the UK have had a chance this year to have their code run in space the AstroPi board is what we call it the sense hat this is what it looks like so we've got a little 8x8 grid you can that's an RGB LED matrix it's got a bunch of sensors so you can get the temperature humidity pressure gyroscope magnetometer and it also has a mini joystick for input we've been through a lot of testing of getting this hardware suitably acceptable for space for flight in space and it's gone through all sorts of vibration testing and all sorts of things to make sure that it's safe to be in orbit it's going to be mounted on the wall in one of the modules on the ISS and it's going to be there after Tim Peake comes back so we're hoping to do more things with them once they're up there this hardware is going to be really handy for a lot of people as well not just for the competition so this should be going on sale within the next couple of months really handy for a lot of projects so just to finish off we've got this education summit have a look at the rest of the talks on this track for the rest of the day so my colleagues and I and some other people from the community we have a lot of education, Raspberry Pi and all sorts of other things and also at the weekend we have some sprints so if anyone wants to come and hack with us on different educational projects and hopefully we'll have some teachers there and see what they have to say as well so thanks very much and I will close for questions so do we have any questions hi Ben thanks it was a really good talk so I'm quite obsessed with space just as much as I am about programming could you tell us a little bit more about the tests you had to actually put the hats through in order to be able to take it up into orbit yeah so I don't know an awful lot about this because I wasn't part of the testing team but I kind of hear a lot from it we've got a developer called Dave who's been doing all these tests and he's really keen telling us all about it so for the actual launch so for it to the rocket the shuttle to go up they have to, it vibrates a lot so they have to make sure that it doesn't break and break apart during the launch we have to make sure that there's no kind of radioactive materials coming out or anything kind of bad leaking out into the air that could be harmful to the astronauts they have to kind of shatter on with a hammer or something and see kind of what bits come off and what could be harmful and test it again after that and also things like heat that it doesn't gain excessive heat we've actually built a special case for it which is probably the most over engineered case besides the one that we made recently for general use that's ever been made it's a great big giant aluminium case that has the matrix the LED matrix shown a little hole for the camera and it's designed in a very specific way for the heat not to radiate so make sure that it doesn't get hot to the touch even radiate out I like your talk I was just looking at the Raspberry Pi homepage so I have a question are there any bluetooth possibilities with the Raspberry Pi so there's no built in bluetooth on the Raspberry Pi but you can use the USB dongle so if you have some bluetooth device that you can you can do that I think we use the remote the remote for that is bluetooth and I've seen people do projects with that waving the weave around driving a robot forward and that kind of thing it's definitely possible to just need a USB dongle the code that you showed it's quite simple it's meant for kids to be able to use of course and I don't know if the Raspberry Pi has got any visual programming environments like the for instance like the logo on the OLPCL X1 I don't know if you've ever seen that but it's very simple just drag and drop things and then make the turtle do stuff but I was actually thinking that with something like physical confusing it would be even nicer to have a physical block dragging or block aggregation do you know of any projects on that direction so the Raspberry Pi comes bundled with Scratch, so Scratch is a popular visual block based programming language, really good for beginners and really good for young children as their first programming experience not having to think about syntax or even bothering to type anything but just being able to click and drag and drop so that's Scratch is pretty installed and there are possibilities for extending that to be able to use GPIO so you can actually drive robots forward with your drag and drop programming Scratch we tend to in our mind we tend to look at Scratch as the first step the second step is really good move above and beyond Scratch called Sonic Pi which Karyan discussed this morning it's based on Ruby so there's not as much precision required in the syntax not quite as much as Python even though we all like to think Python is great for that but we see tabs and we see spaces and we see colons kids don't really see that stuff so Sonic Pi is a nice step forward before they get to Python they can do more and there's also turtle in Python that's available as well so that's another good one there's no other questions so thank you very much Ben


My name is Roman Lodin and I am the booth manager of ST at Embedded World. It's a great pleasure to tell you a few things about the main blocks of our presence at Embedded World. So ST is doing lots of stuff in the embedded world, right? Absolutely. So this year we expanded our presence. In fact we have two areas. One is the STM32 fan zone in which we try to bring all the makers, engineers together. So here we are hosting a lot of companies, students, makers, partners that are working with our products. And on the other side, on the ST booth, we are showing all the new cool products and solutions from ST. And here I think one of the key products is STM32L4. It's a great pleasure to have Bertrand with us. Hi, so who are you? I'm Bertrand Denis, product marketing for STM32L4. So we introduce... Let's walk towards the world you have over there. You're showing it right here, right? Yeah. So it's a discovery kit of a new member of STM32L4. So in fact it's a smart watch demo. So it's stacking a discovery kit with Bluetooth flow energy and MEMS shield. And in fact, well it shows up thanks to the pro-marked graphic acceleration. We can have a very effective demo. So both showing performance in terms of graphics acceleration. Let's stand over here one second. So it's an ARM Cortex-M4? Yeah, it's an ARM Cortex-M4. And it's really excellent in terms of power consumption. Plus it provides very good acceleration etc. So this new member now has up to 320 kilobyte of SRAM, 1 megabyte of flash and new features, camera interface, double-can, char etc. So it's ultra low power? Yeah, it's an ultra low power. So best in class in terms of power consumption. It's enabled for the customer to make amazing product in the IoT for wearables. You have some demos already? Yeah, yeah. So basically it's providing more things here. So you can see for example... On the speaker? Yeah. You can run a kind of small game. So there's cheap graphics? Yeah. How do you do the graphics? The graphics, in fact, everything is undone by the chip. So it's directly connected to the LCD. There's no GPU, right? No, no, it's not GPU. It's really of Cortex-M4, so with this ultra-low power product which can handle this. So thanks to this it gives possibility to customer to design great product and especially with very long battery lifetime. And on top of this also, we announced the new STL32IUT discovery board. So in fact it's with STL32IUT as well, but with the Wi-Fi module, Bluetooth and Subjigerts. It also has NFC and all the sensors, including proximity sensors, microphone, magnetometers, 3D accelerometer, 3D gyroscope. All the sensors from STL32IUT. And you can connect to Amazon, IBM or Microsoft. And so you can use this small board to do amazing things. And it's something that people have not been able to do with Cortex-M4 before? Yeah. What is the latest STL32IUT? Yeah, what is really unique is, again, we're getting power consumption. All of this, which generally you can have this kind of product using MPU. And with this, you can run some very nice things just with Cortex-M4. Very efficient power consumption. Cool. All right. And let me check some more that you have right here at the booth. Hello. So who are you? Hi, I'm Renau Bussero. I'm in charge of product marketing for high-performance STL32 devices. Actually, we can do a quick tour. Yeah. You can start here. OK. So here we are looking at the entry of high-performance devices. These are Cortex-M4-based devices. You have devices that are offering 100 megahertz performance. With this level of performance, you can already do crazy stuff. Like voice recognition. You can say words. They are going to be recognized. You can do some audio processing from the microphone maps. So this means that you can do beamforming, for instance, to just remove the noise from people talking next to you. The sound can be directed to you. This way, you can then do a clean voice recognition inside the microcontroller and the entire area. Yes. You have five microphones here. And you can do beamforming in many directions, with also like echo cancellation, for instance. This is potentially the best smart speaker solution, right? You want to do more assistance? Yes. I jumped. After this voice recognition, which is done inside the microcontroller, we can jump to Amazon Voice Services. So here we have a Cortex-M7 device running at 216 megahertz inside our STL32-S7 series. With this product, we are able to run Amazon Voice Services. There's Alexa, the API and everything. Yes. So we are running the HTTP 2.0 inside the microcontroller in an optimized way for microcontrollers. Here we have another STL32-S7 devices demonstrating here a nice high-speed integrated interface. So the high-speed file has been integrated. So this is very good for fast data transfers. And here, that's a very great technology. This is space real recognition. So we are able to recognize 150 or 20 seconds of space and give up and grant access, for instance, to a people. How can you do that in Cortex-M7? It has that kind of performance? Yes. We are offering 216 megahertz from Flash with a lot of resources integrated. And the partner that we are working with is called TerraProbe and has optimized our software for microcontrollers. We move up in performance here. We have a lot of people who need to learn it. So here we have the highest performing Cortex-M based product in the world, STL32-S7. So this is for 14 nanometer process running at 400 megahertz Cortex-M7. So we are over 2,000 core mark performance from Flash. This type of devices is boosting the performance, boosting the resources, new connectivity like KNFD, for instance. And we also invested in security. So this product is something very important security challenges in IoT. For instance, this product comes with public and private keys inside the microcontrollers. These can be used to sign an encrypted software. So an OEM can deliver an encrypted software to an EMS. And this software will be protected and decrypted inside the microcontroller. And we are working with Sega to, for instance, demonstrate here the programming and the counting to avoid cloning of the device in the field. So security is one of the big challenges for the entire world? Yes. And here you have a solution? Yes. And it's hardware encryption? Yes. Secure elements? Not secure elements, but internal cryptography and provisioning of the keys.  With Sega, with SD, MWIN, embedded wizard and TADGFX solutions. Optimized for my taste. How easy that the guy can be put on the... Whether it's a coffee machine, a thermostat, a control panel, an alarm system, or an embedded device, wearable. So the ST world, that embedded world, the ST world is pretty big, right? You have a whole fan zone. Can we maybe introduce the guy over there? He was a... You can maybe... Sorry? Yeah, there was one guy who can show us the fan zone. Oh yes, where is Roman? Yeah. Let's find the fan zone over there. Hey, excuse me? Yes, yes. Guys, we are live here. Roman, Thomas, to introduce the fan zone. Can I jump in here? Yes, we are live. Yeah, but we are in the middle of something, so... Okay. Oh, where are you streaming this? Okay. Right here? Right here. We are prepared in the lounge of Teniherrs, who will be performing at the ST Forum. Teniherrs is the The Arduino Lady. Arduino Lady, yeah. I've seen her at a trade show before, so she's going to be interviewed? She's going to make a presentation here. She's going to make a speech, she's going to talk about Arduino and STM32, because we are moving STM32 to Arduino World step by step, because the Arduino community is huge, and we have a huge community around STM32, so now we bring... Maybe you know it's powered by ST, right? Mostly. Okay, basically we are entering the Arduino World now with our boards and with support of Star Autoboard, and Teniherr will talk about it right now for our visitors. Is there any chance you can show me around some of the fan zone stuff that you see here? Let us announce Teniherr first, and then I'll show you all the cool things we have around. Okay, let's check. She was walking on here. This device has a MacLeo on it with the infrared here, but he has it responded. And walking right here. Some of these things. Cool. Let's go. Right here. So it's just about to happen. That's a lot of boards.  Hey, what are you doing here? here you're getting a talking board yes what are you gonna do with it you're not a lot to say it that's gonna be cool so people are queuing up for some free boards that's a lot of high-number that's two billion that's me good afternoon Nuremberg we are here at the STM32 forum how are you today we are very hot very excited and we are going to introduce our super new guests that already performed yesterday brilliantly ten hours from Arduino he's going to play our song and tell us about Arduino board and ST that's what I'm doing. Alright ST fans if you can hear the volume of my voice that means you know I'm from California from Silicon Valley so in Silicon Valley children still need to learn about Arduino they still need to learn about technology and I'm wearing one of my prototypes now and we'll get some other fun technology going on as I perform a song for you so you might know some of the words in the lyrics because it's a technical song but this is one of the ways I help inspire kids to get into electronics so let's start it off we can make it louder if you want it's my music video waking up want to make how can we innovate a better modern city IOT you know me writing tweets hope my view is new and witty teach the class spread the word I'm a man from a homemade comedy we code this connects that hack that all my girls code and fill it pretty this thread is steel it's stainless steel this thread is steel so it had to heal this is how we make this lady is crazy yeah so you see you have a lot of nice presenters and shows over here but on top every day every hour we have a different partner speaking about their solutions link to ST technology but not only talking in the forum but we have a lot of them hosting them directly in the fun zone so as I said in the beginning the fun zone is bringing a concept of meeting and providing a place where the community around STM32 is meeting so for example here we have a couple of nice projects from a student you see they made a gameboy and you can run an emulator on the STM32 is it better than the original I'm not gonna say this may be better but it's still a lot of fun because you can use a screen you can also use paper or paper yeah it's running on the STM32 F7 so basically imagine this is a general purpose microcontroller running cool retro things like a boy how long did it take you to do this I think two weeks two weeks programming yeah I have no idea hello yeah I've created the panel and the user interface to create something on the panel yeah it's also created in like two or three weeks so it's because ST provides a very good environment to set up projects real quick it's like KUPA mix and some free IDs is that your name Thomas yes it's also my name is your logo this is not my logo this is logo of our school so yeah okay you only go to that school because you're Thomas right yeah indeed yeah normally they are more Thomas's but yeah but this is this looks beautiful can I buy this well yeah not at the moment but maybe maybe in some time if you can't give you a contact information and we will contact you about it's all in the table you might be able to do a lot of money in the future with cool ideas right yeah yeah what you want to do well yeah we want to create our own stuff actually and the the nice thing about ST is that the chips are you can pay them as a student you can pay the boats as a student so you can learn to work with everything that ST provides with other microcontrollers it's on sometimes not that easy or not that simple not the same it's not so expensive right no it's actually not expensive the board itself with with touch screen LCD with you USB internet it's like 50 euros so it's very cheap 50 euros yes it's nothing for what you can do with it like the gameboy emulator the first version was made on the same board like the draw thing so yeah you can do everything you imagine I think with those boards it's nice do you see some cool stuff over there yeah the cool stuff is everywhere like here's something with motion control someone made so yeah indeed yes thank you to my very good speech so as I said you know we are hosting here partners makers and one of the partners is see us and I have a blog with me can you say a little bit yes we are very happy to cooperate together with STM in order to have our products covered with the best where you show it yes it's over there let's go it's see was we are actually a Swedish company with here are you are you doing stuff with this yes the idea is to use all the STM devices in order to so it's for the shopping cart because the idea is whenever you go to the shopping centers and you would like to understand what are the details about the product that you are to buy and what you do is just take the item out of the shelf approach it to the device and if you are happy with the offering is it using barcodes or it's using NFCs in order to share information with the device this is possible and here we are using STM development both in order to show how can be utilized in such a device the same other areas for example and the same one can be used also for here we are monitoring temperature and humidity so there's a lot of cool stuff around here yes of course it is an excellent show in which they can say a little bit more about their it's all around here okay perfect then can we go around some more yes so okay let's continue thank you by going so so we had students startups we have partners and one of the companies developing with the technology is also so Vijay are you filming yeah okay yeah so myself Vijay Narayanan and I'm the CEO of the Metalapse is it a heads-up display yeah so how does it gonna work recognition device just your control device just this one so what's inside having most of the ST components from microcontroller to the sensors battery this battery is one of our yeah it's a rechargeable one glass for a month and oh and then in the car you do gestures exactly so if I want to call someone so I can switch profiles and I can just make a special gesture I can present phones phone calls to pre-set SMS then I can control any music application what kind of sensors are there in there to do this cameras or time of light sensors that's the best way to do gesture so you can see that you know I can is that safer yeah many people buy it already campaign more suggestions on new use cases for example there was one guy who was disabled and he was yeah I ended up using so regularly that he said that even when I'm eating I it's near me and I'm doing some gestures so accidentally so we made a pause gesture for him so that he could pause it while he's eating and then there was another person wanted to control the ways application because it's a very distracting app and you have to click multiple times to report an incident so you wanted to shortcut it with one gesture so we are getting a lot of fantastic ideas like that so let's continue in our tour one of the next solution that we are hosting here is expat guys they came all over from Australia to November to be hosted on our fun zone so I'm the managing director for expat you can tell my accent I'm not Australian but our team is located in Adelaide Australia and we are a IOT infrastructure platform can I put you on hold one second I got to grab my engineer real quick so I got this right here all these things there the infrastructure so and what we have is an IOT platform that is software based and we've been using the ST microcontrollers as part of the solution set in fact we've got ST microcontrollers, sensors and basically the full gamut of what ST has done the whole demo here it needs to be connected and there's all kinds of stuff happening right so in this demo what we are really trying to show is you can have an existing technology so let me show you for instance you press this button and it unlocks you press these buttons and it lies press this button and it goes up and down that's an existing system in a building today now most people look at it and say okay I have to tear it all out before I can move forward with IOT and what we're saying is no you don't do that what we do is you take sensors that are built around the ST microcontrollers with traditional two wire outputs and you can take those sensors and now all of a sudden you have an IOT solution that's integrated with your existing solution so you don't need to change stuff but you're going to have to add a few things and maybe make some minor modifications but not major changes so we're not shipping in mass volume so our first project is going to be installed this month where? it's in Australia okay it happens to be in a health care center in Australia so we're taking their existing architecture that was there and we're adding so this just happens to be the sensor board that we have so as I said by adding this sensor here you now have the capabilities of controlling it remotely from your phone and so forth and not only can you control it but you're also getting the output so that you can understand the state so when it's going up you see the green light goes up even when I'm hitting it up here the green light will still go on so it understands the state of the entire system moving back you can also add additional sensors like in this case this happens to be battery powered so you want to be able to track the state of the battery you want to be able to track the current and how it's going to make sure that the battery is not going to run out these are all the type of things that you can add to a system to make it IOT compatible without having to tear out the entire system and it's focusing on IOT and you can write it down that's right and ST is the center of that firm for the actual hardware solutions that we have the logo meter, my favorite project can we walk over there to the... one more here maybe we will wait for Julia, you can also do some other ideas before all those parts are we've helped you breadboard, we've helped you learn all the different features in the software so each lesson has just different like four loops so what's on the wall over there? so look now we have seen some cool projects of students of our makers but how they can develop their projects it's not only about the product itself they have to do it seamlessly in a quick and efficient way to support them in this activity we have a lot of boards so people can buy those? yes so first of all people can get them here during the show because we are distributing every year more than 5,000 boards people can pre-register before the show then they come with the brochure and they exchange the brochure for the kids but of course there are so many boards we cannot distribute every board like this so for the remaining they can buy them in our STM Party to Fan Show because if we are in a fan zone and the fans they want to buy and to get some goodies and things to develop so there are lots of different ways to develop exactly so this is the platform with nuclear boards, expansion boards which can allow every engineer, every geek, every maker to make a very quick prototype of this board so imagine you take a board with a micro as a base one and then you build it adding blue energy for Bluetooth connectivity you can add sensors to detect the humidity, movements and so on so this way customers and people can develop prototypes or evaluate our products very fast and efficiently so I tell you we are on the fan zone so we are welcoming all our fans and we give them the opportunity to make a testimony why they like our products especially why they like STM32 by doing that they will get a cool t-shirt like I have with nice tags on the back so if you know Z-Coding you know what it means and if they do the testimony they get a t-shirt and after making a photo in the t-shirt they post it on the social media they could win a DJI Phantom Pre-Drawn which is full of ST components inside so we have 7 STM32s inside the DJI 7 yes some of them are for the motor control so we have 4 propellers there is one which is the main device the brain of the complete unit so there are really 7 of them maybe power, connectivity, all kinds of things yes all these functionalities are driven inside the drone by STM32
