Mae'r cyfnod sydd yn ymgyrchwch, a'r cyfnod sydd yn ymgyrchwch, Should he keep his comments for himself? What do you think? Go on. Well I just think in terms of the comments, I think human nature tells you that you'll respond. If someone criticises you, very rarely do people just stand there and take it regardless. Do you know what I mean? So I think he's always going to come back with something if someone goes, ah you've made another mistake, he's always going to go. Well I'm going to say that's a joke and that's a joke. But he ain't right, I think it was he ain't right. He's made the really good thingy a baron today. He's made some comments a baron today, he should have really just gone okay and not done exactly what you said and brought attention to himself and said well I'm going to get better and I'm going to work harder to eradicate that mistake. He said them people will look at him and go and prepare to give him the benefits of that because he knows and he's working hard now. I think sometimes that's immaturity, but we all do it, it's a defence mechanism. Rooni used to do it, when Rooni'd get booed at Goddushon, what did he do? What did he do? He'd do all this or Aramfield or Jolly Barton put the shorts down at Goddushon. What does it say in Carl's book about criticising to the top players? Oh no, no, they just take it. They just take it and accept it and go yeah okay because they know what they will. I think for me, I think for me, I think he's got a right to come back on the criticism if he wants to. I thought it was very clever the way he said about England players. He said about the England players because a lot of these comments that are coming in, Ian Wright, Gary Neville, who else did it say? Danny Mills. Someone else I've seen. They're not bothered about it being if he's in good form or bad form or whatever. It's what his form means for England. That's all they care about. And ultimately, for him, as I said on the final word, I thought it was interesting his comments that he made straight after the pitch where he was like, I made a mistake and I rectified it by making that save. That's just me. I think it was good that he admitted he made a mistake, but also on the same token he sort of go and say, I just think that, I think some of the criticism that he gets from everyone who finds more than anyone is just like, get your head down. Because I think who was it? Someone made a really good point. It might have been Danny actually from the blue room. I think he said he did that interview with Carvel Llewyn. And he said Carvel Llewyn has took just as much dick if not more than Jordan Pickford ever has. And Jordan Pickford should take more in theory because he's England's number one. So he's on a higher pedestal. And yeah, when you look at Dom, he doesn't seem to dwell on it. He's more just worried now about getting better and being better. Like he's took the criticism, he hasn't commented on it and now he's seen the benefits of it. If he was playing for England then getting stated. That's what I'm saying. But he's probably took more criticism than Jordan Pickford. Well Pickford might just be talking about not necessarily Evertonians giving him stick. The fact that pundits giving him stick. That seemed to be worry level. Because he mentioned Joe Hart, didn't he? He said, look at Joe Hart, he was the best goalie around when he was England's keeper. And everyone slated him for it. But that wasn't... Footballers have got to get away from thinking that comment, so why people go bad. No, no, no. But Joe Hart went bad because he went bad. Because he went bad. He went bad. But don't you think that was part of the fact that Joe Hart started going bad? Because at some point he probably stopped thinking he had to get better? Possibly, but the other thing is we've got to get away from the fact that we think footballers are immune to any criticism. We're great when we're talking about mental health and we go, it's really important because these are robots. They can't play seven hours every day and then play a match. They can't play three games a week because they get tired. We defend that when we say players can get tired. And we'll defend it if there's a problem. Like when Aaron Lennon was walking along the motorway because he said it's gone. In terms of mental health. Footballers are immune to criticism. They're not. Now, whether that means like what Dean Smith said, a filly, was like, I asked my players to stay off the likes of Twitter because it doesn't bring any value. He said there's zero value in social media if you want to be that he said. Because someone will always have a go at you. You only need your family and you only need your mates. You don't need anything else, blah, blah, blah. So he tells his players to stay away. I think you saw him up Jack Reelis, to be honest. Jack Reelis has calmed down this season and more or less stayed away. So there's that side of it. So maybe Pickford needs to just stop going out and beffing and let them film looking like they did. See, that's the other side of it. That's the other side of it, isn't it? That's the other side of it. When we've seen the video of him over Christmas, he's allowed to go and have a beffy, but the problem is that... Don't draw attention to yourself and don't revel in it as well. That pisses Everton fans off more than mistakes he makes. Because, like I said, Saturday. I can't remember him conceding a goal for us like Saturday where it rolled under his body. He should have done better with some goals, but that Saturday was a proper mistake, like a goalie mistake. But I haven't dwelt on it because I thought he doesn't do that all the time, so it's one of them things.  Especially you've got... Gone beffing in Newcastle when you know it's going to draw attention to you. Like, there are things that... If you want people to stop questioning your professionalism, maybe, then that's the things you have to cut out. You have to cut those things out for them. If he was just Everton's goalie, they'd probably just go. It'd probably be that big, the story, or whatever. But because he's England as well, it's everywhere. So it might just be here if he was doing it just as a keeper. But because it's England, he's everywhere. And he needs to get... That is the one criticism I would really have of him.  Don't get involved with the fans. Okay, fair enough, he didn't in the tune of Newcastle. Well, he was waving to them when we were tuning up, wasn't he? But he didn't down there, which is sad. But don't put yourself in that situation over Christmas going out and beffing in and down. It's great puffing your chest out and going, look, you're not going to affect me. But it obviously is affecting him because he's come out on the defensive immediately. If someone... The best thing he could do is if someone says to him in an interview, you know, Gary Neffles being critical of you this week, he could try. As he... Oh, don't know. Don't take any notice of anything he says. Something like that. Because then it puts it back on them people, or I don't know, managers do it all the time. They'll ask a manager to go, a club says it all the time. I don't know, don't read the papers. I don't know. Doody, nothing of interest, the way they do it. You control what he can control. And I think that's the one thing I would say about him. He's a young lad, he's got... He's got to mature, I think. I think that, you know, he's a father now, and hopefully that all plays its part.  But I think, yeah, just get your head down. Just get your head down. And I think, you know, we all know that technically he's a very good goalkeeper. We've seen it, we know, we've all seen the first season.  How many times was Nigel Martin up there being, and people filming him, and lads doing this and doing that? I can't imagine Nigel Martin has ever been up there. No, but yet still playing unbelievable goalkeeper when he was 38, 39. Oh, that's it. And it's that judge. We said it on the foot. You show us something the other week. It was like, how good do I really want to be? We don't have another way. We were, and other players were trying to do it. If your job in Pickford, and you think, now, when everyone's getting on my case all the time here because of England's goalie, the best way to deal with that is withdraw from everything and just focus on your game. Play well for Evanton. Train hard.  Shall Gaitle still pick you because you're still probably the best English keeper. And then people will get off your back.  So control what you can control. Cut all that noise down. And then, if it's a goalkeeper mistake you make, well, think you've got goalies do make mistakes. End of story. I think the reason why he gets criticism from Evertonians is all the noise that goes with him. And I think until he gets control of that, maybe he won't improve, but I'm hoping he does. Yeah, I am as well. Grain prices, good evening. All, Gaddafew says evening, lads great results again, but all the papers focusing on Pickford and the mistakes again. His silly claims of being picked on in interviews do not help. That's why I can't have the lad. He's an unnecessary distraction. He needs replacing sooner rather than later. Gaddafew says 100% spot on. He's been 50-50 for me on the pitch, but off the pitch he's a jailer stream, whether it's the daft comments or getting boozed up at the bar. Okay, there's nothing wrong with enjoying yourself, but he's supposed to be a professional and a role model for young goalkeepers. Personally, I wouldn't want kids looking up to someone like that, looking at nerve instead of drinking with the rest of the team and sitting there with a brew. Yeah, I mean, the role model thing is... Yeah, I don't know, I've got kids, so I don't really... There are always going to be role models because of the way they put on pedestals, whether they're a good role model, a bad role model, and a different role model, but all of that other stuff. I think you just cut that stuff off for your own self. If you've got 15 years at the top, make the most of it. Make the most of it. If he does that now, if he does that now and gets older himself, he'll go up another level without a shadow because he's ability-wise, he's got that in his game. And I think it will help his decision-making as well.


Hey everybody and welcome to Ask Engineer. It's me, Lady Aida, the engineer with me, Mr. Lady Aida on camera control. Thank you. We're both right golfed today. We're broadcasting live from downtown Manhattan. That's where we have the 8 foot headquarters. We do all of our kidding and shipping and packaging and coding and we do assembly. We do all sorts of stuff there but right now we're gonna hang out with you guys for like about an hour. Me and Mr. Lady Aida and we had a full packed show of goodies to show you. We gotta leave a little early but the show goes on so we're just gonna condense the show for all the important things that you know and love and want to watch each week.  Yeah. Okay tell us about that show. On tonight's show The Code of Spring 8, 10% off in the Aida food store all the way up to 11.59 p.m. Use it in sport and open source hardware, company, manufacturing, electronics in New York City, USA. Talk about some of our live shows, got a JP's product pick of the week highlight, some main New York City factory footage, a 3D printing speed up. We've got Eye on MPI. This week is Rich Tech brought to you by Digikey. Thank you Digikey. We got some top secret previews of some new trinkets, some new products. We can answer your questions over on Discord. We can join like all 33,000 of us, aidafruit.it slash discord, discord.gd slash aidafruit. We're gonna talk about some free stuff, all the things you can get in addition to the discount code, all that and more on Ask Engineer. Yay. Yeah, okay. So don't forget Code Springy and what do we get? Springy into Spring. Okay. Springy, what do they get when they start putting stuff in the cart? Yes, when you order from aidafruit.com, we give you free stuff. Like if you order $99 or more, it'll give you this beautiful gold and black coaster with the aidafruit logo and some little rubber bumpers. It's great for putting your hot or cold drink on it and it will keep your desk nice and clean. And we're still doing our $149 or more giveaway for the KB2040. It's a pro micro pinout compatible microcontroller featuring the Raspberry Pi RP 2040 chip with flash memory buttons and NeoPixel, USB-C and cast-related pads. So it's a great little microcontroller board with a nice powerful chip, a good upgrade to the pro micro. $199 or more free UPS ground shipping in the continental United States. And last but not least, for $299 or more orders, we give you a free Circuit Playground Express. It's round and colorful and has sensors and buttons and it works with Arduino, Code.org, CS Discoveries, MakeCode, Circuit Python, and many other languages. It's a great way to get started with programming or electronics without any other tools. Okay.  We just got off the air. Do check out all the places we post our videos, all the places such as YouTube, Twitch, Facebook, Instagram, Reds, you name it. Yeah. Thank you JP for doing show and tell. On Sundays, we do from the desk of Lady Aida in the great search. Watch that there too. And on Tuesdays, we do JP's product pick of the week and we have a highlight of this week. Take away JP. It is the SHT 41 Temperature and Humidity Trinky. It has a quick, easy monitoring solution. And you can see here, this just slides right in. And that's a thick enough board that it actually stays in there quite nicely. Here you can see every two seconds, I have it logging the temperature in both Celsius and Fahrenheit. So it's about 78 degrees in here right now. And humidity is at about 29%. I can probably skew that a bit either by just touching the sensor that'll probably warm it up a bit. Oh, it's cooling it. I'm cooler than the air. You can see the humidity jumped up there just because of some perspiration on my finger, or if I blow on it. So if we give it a little warm, hot breath there, we got it up to 83 degrees and about 80% humidity. The SHT 41 Temperature and Humidity Trinky. Okay, and don't forget on Thursday, you can watch JP's workshop on Friday, deep dive with Scott. With Scott, yeah, Tim. Or 5pm Eastern. And Scott's not there. It's deep dive with Tim, but usually it's got now. So do tune in on Fridays. Okay, let's do some Python on hardware time. There's a couple things you want to talk about this week. Yeah. You wanted to talk about, we have 903 released. Do check out the latest. And then there is expressive chip news. Well, sign up if you want to get notified when we have this ESP32C6 feather. It's still in prototype phase. That's why it's green. But you know, one day it'll not be green. It'll be black and how you know it's released. And then you'll get notified when it's in stock. Another thing that I thought was kind of cool is we saw a preview like almost a year ago about the ESP32P4, which is like a very powerful processor. You want to scroll down a little bit? Yeah. So this is like a like it's so essentially it doesn't have Wi-Fi, but it does have Wi-Fi. It wasn't clear at the time. So it's Wi-Fi, but it has like dual core 400 megahertz processors. I don't know if it's in 10th silica or risk five. It's got like CSI, DSI support, HDMI, just a lot of display, very serious displays, which they've been sort of practicing a little bit with the S3. So the P4 is really cool, very big too. 32K of built-in SRAM and of course PSRAM can be added. There's 16 kilobytes of ROM. I think that's just to run it. Oh yeah, they go up to 64 megabytes of PSRAM built in 768 kilobytes of SRAM and then through 2 kilobytes of low power SRAM and they're really good at low power stuff, a few DSP, but yeah basically display stuff is where it seems to be. I've built in decoders and stuff. So yeah, obviously we all are interested in the chip when it comes out. We'd love to answer goodbye on support. Yeah, I got a question for you. So they have independent in deep sleep. So when a chip maker says something like this, how would they handle that when they say independent? Like what are they doing? That's a good question. What are they doing to say independent? Is it another chip that does it? It's like waking up stuff, watch dog as I say. They could have a low power chip like a risk five core. They've done in a couple chips so far. They've had the main core and then a very, very low power risk five core. So there could be some sub-processor that is like in deep sleep of the main processor. It is doing little tasks like checking for a voltage or communicating or R2-T or checking for pins and stuff. That's what that means. Yeah, that'd be interesting. As someone, Todd mentioned the chat that you know they're keeping the ESP32 brand in which they don't need to, but like everyone knows what that is. So yeah, I mean like it you know yeah it's a little confusing if people say ESP32 it's like well do you mean the classic or do you mean the S2 or the S3? But you know it is a very strong brand and it probably is something to that name that means something. It could be that's the tends to look like a 32-bit family. Yeah, I don't know. Yeah, I mean like they do have the ESP8225. Well for tech naming there's Windows, MTO in the chat says .NET. There's a lot of terms. I remember I did work with Sony a long time ago. They had memory stick, memory stick dual pro plus, memory stick dual pro extreme. Yeah, it's challenging because on one hand it's like you know you want to lean on a good name, on the other hand it could be confusing. But you know like the AVR series I got now had a you know still making AVRs and they've changed quite a bit. So I'm kind of curious about how they're going to do independent deep sleep like is another chip. What is that thing? Like what is it? Yeah, the deep sleep is very interesting, very innovative on that. Yeah. Okay, so what else did you want to talk about? The other thing that's kind of cool is Todd bought these cool mini videos about using, oh go click on the mastodon link. So these neat videos, I don't know what's going to happen. You can play the video. So we added this thing called bitmap filter for the camera and then like I kind of like never got to the projects I wanted to do with it. But I like that he's like revitalizing this thing which allows you to, it basically allows you to set up a kernel for a convolution filter that you can then apply to a bitmap. And I believe we actually did three by three by three. So like true RGB cubic filter. So you could actually like have different channels affect other channels. And others would be kind of cool because you could like maybe do like some photography filters on it. But like I said, I never got to it. So it's kind of interesting to see that he's like, oh, like I'm doing like process, like I'm kind of processing like art. It'd be cool to have pie processing be like, you know, a Python version of processing for making these kind of cool, funky filters. That's cool. And yeah, thanks Jebler for bitmap filter. Yes. Is there anything else you want to talk about? That's it. I think that's a lot. Yeah. There's more, I mean the news. Tons, yeah, tons and special thanks to Ann, our editor-in-chief for the newsletter. We deliver this every single week to your inbox. And you can get that at AdafruitDaily.com. We keep it separate from your store account because we do not spam. Okay. Some open source hardware news. First up, we're a sponsor of the open hardware summit. They posted up the sponsor list and more. And do you know how many open source hardware contributions we have? At the time it was 740, but I think it's actually like 716 or something like that. Every 745 or something. Yeah, it's a lot more. And so I think like right now we're, well, I know we're the top contributor, but then people make open source hardware based off our stuff too. So there's, it's an ecosystem, it's good. So we're really pleased to see the certifications going. You're doing hardware and you just want to send the signal out that you really did open source hardware. There is a certification process. You can do it super easy. We do it. And for the folks that are going to the summit, have fun. Yeah, I think it's in Canada. Yeah. So next up we have our Adafruit Learning System Guides. What's on the big board this week? Speaking of open source hardware. Okay. We actually had a lot of updates. A lot of these like Raspberry Pi updates. So we've been doing a lot of testing to make sure that all our stuff works with the latest version of Bookworm and the Raspberry Pi 5. You'll see a lot of updated guides. Liz also did a new guide for the TCRT photo reflective interrupt sensor. Thanks Liz. It's a simple sensor, but still need to guide. And we also have a guide for the LTC 4316 address translator. And I think last week we had the watch winder and the IOT batteries. So a lot of people working on projects, you know, they're coming a little burst. You'll see a couple of projects get published in the next week or two. Okay. Cool. Let's take a quick break and do some factory footage. All right. Next up. So for 3D printing this week, we just have a speed up and then we're going to roll right into ION NPI. So now Pedro, take it away. Okay. Don't forget the code is springy. Let's do some. ION NPI. Part 2 by DigiKey. This week is Rich Tech, your power partner. Yeah, partner. Hey, Data, what is the ION NPI, the new product introduction of the week this week? Okay. To no one's surprise, it's a power chip from Rich Tech. They're really good at making power chips. So this week it's the RT-6160A. It's just like this. It's a very small chip with, you know, BGA. Mounting is designed to be very small, but don't let the size fool you. This is a very powerful chip. This is a very interesting and very useful, kind of all-in-one power supply and management chip that you could use for, especially something wearable that uses batteries. It's a three-amp output buck boost converter, which is like a massive amount of current, or sorry, the switch I think is probably three amps, which means still you can get, you know, an amp of load or more. And it's a buck boost, which means it runs from as little as 2.2 to 5.5 volts. And then the output can be kind of anywhere between two and five volts. Also, say like 2.83, 3.3, 3.5 volts are all valid. And you can use the I-squared C interface. It has to configure the voltage output. So you can dynamically change it. You don't have to use resistors to fix the voltage. If you want, you could start running your, you know, code at 3.3 volts, and then you can drop it down to 2.8 later. Yeah, sorry, it does have up to three amps of output current, especially in buck mode. It's going to do great for that boost mode. It's 2.5 amps max, but still a huge amount of current. And an amazingly low quiescent current of one microamp non-switching, and I think another one or two, like two microamps total typical quiescent current, which is like unbelievably low, even most LDOs don't go really below like 10 microamps. So, you know, amazingly low quiescent current, high current and high efficiency output, and it's configurable over I-squared C. So it kind of does everything you need in the power supply chip. You know, a lot of people ask me like, when would you use a buck boost converter versus an LDO? And I use LDOs all the time. In particular, I use the RT9080 a lot, which I'll show in a second, which is a LDO from RichTech.  And you basically, you know, tweak the amount of voltage on the FET until the output is the voltage you want. So, VN always has to be above Vout, so you can have 5 volts in, and you could have 3.3 volts out. But then all that current in between is burned off as heat. Like that 1.7 volt difference, you have to dissipate that out.  As long as the VN is pretty close to the Vout, maybe, you know, the dropout is so minimal, maybe it's still within 90% efficiency and low noise. Like I mentioned, that I really like the RT9080. This is like, I'll go to LDO for our low cost boards where we don't have a buck or a boost converter. And what's nice about this board is, it's got, again, very low quiescent current, like 5 microamps or less, which means, on this itsy-bitsy ESP32 here, if you look on the left, you can see in deep sleep mode, the ESP32 is, you know, maybe 5 to 7 microamps, and the LDO is 3 microamps. It's just unbelievably low current, compared to like other chips, which we use like the AP2112, which has like 50 microamps of current, which just makes a big difference. It's like, it basically means you get 5 times as much runtime in deep sleep as you would. So a lot of people, when they're designing wearable or portable projects, they're going to be powering stuff off of a, oh, sorry, I can just move to the, this is a lot. Like a Xanax. Yeah, sorry. I just want to make sure we don't, we don't skip ahead. They're usually running off of a lithium polymer battery. So the lithium polymer battery, they're called 3.7 volts, but really, you know, they have a nominal of 3.7, but they start at 4.2. It depends a little bit on the temperature, as well, and the drainage. So here this is, that see here is the drain rate. So assuming you have a low drain rate, 0.2 of, you know, if it's a 1,000 milliamp hour, that means it's your 0.2, times the milliamp hour in milliamps is the rate. So if you're drawing like 200 or 100 milliamps or less on average, you start at 4.2, which is well above 3.3 volts where you normally use it. But then as you kind of drain more current, especially high current, the voltage droops quite quickly, and then you very fast get close to 3.3 volts or even below. As you see, even, you know, especially if you're doing spikes of current because you have like a radio or you have a motor, you can quickly have the voltage of the battery dip below your 3.3 volts nominal voltage and it'll go down to 3.1 or 3, but there's still plenty of capacity and current inside. So you want to use something like a buck boost. So when the voltage of the battery is above 3.3 volts, you'll buck it down and use an efficient buck converter so you're not losing any of that dropout voltage. And then if it's below 3.3, you'll boost it up. And a really nice design, as you see here, it's all inclusive. So you'll need one inductor. It's a generic example. You need one inductor, input capacitance, output capacitance, and then a resistor divider to set the output voltage. These tend to be more expensive than just a buck or a boost. And they, you know, oftentimes have a little bit more complexity. But what I really like about the RT-6160 is how simple it is.  You need input capacitance, output capacitance. And you don't need a resistor divider because the default output is 3.3 volts. And then you have, you know, a couple GPIO lines for the I squared C configuration enable and signal. The signal is what determines that I'll show you later. There's two voltages you can switch between. And of course, enable takes it into low power mode. So not a lot of pins, not like there's no like strapping capacitors and like feed forward, and then compare it to the TPS series. The quiescent current here is two to five microamps compared to 15 to 25. So for deep sleep, it's going to make a really big difference. Okay. And then it is a BGA. It's a WLCSP. It's very small. It's designed for like, obviously like very tiny circuits. I can definitely see it being used for audio circuits where sometimes you are going to, like I said, motors, radios, where you sometimes need to connect over Wi-Fi, you have a burst of 500 milliamps or one amp of current. But otherwise it's going to be very low current sipping and you want to maximize that battery because by using a buck boost with this low quiescent, and I'll show you the configurable battery, you can really like get that last five, 10% of battery life out without harming the battery but keeping your circuitry running. One thing just to note is, you know, it's not a wide range input output. It is, you know, basically two to five volts in, two to five volts out. The Apple Curtage 3 Amp is just a lot. Just, you know, make sure that your battery supports that. That's a huge amount of current, especially if you're boosting it. I think in the boost, like I said, it's 2.5 amp. That's still a lot. You know, that could be second four amps out of your battery. So obviously if you're using, you use this for RC circuitry, but you know, a small battery won't be able to provide that.  Okay. Next up, iSquad C is really simple. There's a couple of stats, you know, there's a device you can read and then there's a vout one and vout two register. I think these are all 16 bits wide. And so you can set the output. You're like, why are there two outputs? Because you actually will switch between them, which makes sense. Because usually you would set this up to have like 2.8 volts and 3.3 volts and then use a GPIL to like immediately switch between the two voltages. This means that when you want to go into a different mode, you don't have to send the iSquad C signal over and over again. You just switch back and forth. So when you're doing the radio or you're doing the motor, you can go up to 3.3 volts or you need or 3.5 or 4 volts. And then when you're not using this like high voltage, high power peripheral, you bring it back down. And then if you have a micro controller that has clock, you can PLL adjust the clock, combine that. You could have your micro controller running as at little as 2.5 or 2.3 volts. And at a lower frequency, you can save a ton of current while still keeping your micro controller running. So a lot of power savings can be squeezed out by using this chip. Here's the layout. One thing I like is it is a BGA, but at least you don't have to like get signal out from the middle. You can use this.  It's like you're not using any... Doesn't look like you need any bird vias for it. Well, of course you can. And then there's the valve board available. So ready to go. Input output and all the configurations on little test clip leads. So if you want to get started, all this stuff is in stock. A digickey. That's right. And for good price, it's like less than $1.50 in quantity. It's amazing for a buck boost converter, three amp outlet. Okay. And that is Ion of the Island. Okay. Now we're good to go to springy. Now we're set up for native restore and get all that free stuff too. Okay. Let's go over to... First up. First up, we have the Q-Bot Pro. So I think we have the original Q-Bot. So this one is kind of the same thing. You plug the micro bit in, you get motors and sensors, and there's a sonar for distance and two wheels. The big update with this one is you can now use an 18650 battery, which we do not stop, but you can get them on various online sellers or sometimes I think in some hobbyist chops. And you can then use it as a rechargeable battery pack so you don't need an external battery pack. So we're struggling for the people who are comfortable and okay with getting this other external battery and plugging it in. Keep in mind that we do not sell that battery ourselves. Next up, we have some ESD plastic tip tweezers. So these are plastic tip. So just be aware that they're not for hot air rework and don't get your soldering tip too close to them. But they're ESD safe and they have like these soft replaceable tips which some people might like. So good for picking up components. You can show them really fast on the overhead maybe. Oops, hold on. It's got weaked. This is my pair. It's got a little bit melted and damaged because I was experimenting like, what happens if you do heat it? Turns out you can't. But these are nice and delicate. So they're good for dealing with components where you don't want metal tips for some reasons and you don't want to the possibility of scraping or scratching them. Good. Next up, we have a new BFF for Shau and QDPI boards. This one features the BNO-055 nine-dough sensor plus the BMP-280. So it's a 2-4. It's like 10 or 11-dough, I guess. What's nice about the BNO-055, as you see here, it will just give you quaternion or oiler. This is oiler angles out. Immediately you do not have to do any fusion. You do not have to keep track of your error. You don't have to do your magnetometer calibration. It does it all for you, which makes it a little bit more expensive, but means you can use any processor. Which is great. People really like that for robotics and motion detection. The second thing is the BMP-280 on there is a barometric pressure sensor. And you're like, well, what does that have to do with the nine-dough? Well, you can use the barometric pressure sensor for altitude detection. So you can not only tell the X, Y, and Z coordination in space, but also how high up you are. If you pair this with a GPS, now you can pretty much identify anything perfectly within the confines of Earth's atmosphere, which would be kind of cool. And it's a little BFF board, so you can just plug it right into the back of your QDPI. Or you can solder it directly into the back, if you like. It's got little cast-related pads even.  But a lot of people want to do motion or maybe you want to make it the tiniest little drone. This would be great for that. That's it. Okay. Next up, we have the TSSP77038, the 038 sensor, 38 kilohertz demodulator. Okay. So this is an interesting chip because a lot of people are like, oh, it's an IR remote receiver. Yeah, it is, but it actually does a little bit more than that and a little bit less than that. So we're going to show off our IR receiver in a bit. But what a demodulator does, it doesn't have any brains. Like IR receiver chips usually look for and try to understand whether it's an IR remote signal and they only pass valid IR signals from a remote control. This doesn't do that kind of filtering. It will pass, anytime it sees any 38 kilohertz infrared signal at like 940 nanometers, it passes the demodulated signal along. Why would you want to use this? Well, IR remotes, like I said, you can't send a continuous signal of IR remote on an IR remote.  If you want to use a break beam sensor that is modulated so it's not as affected by ambient light, if you want to do a proximity sensor that bounces modulated IR light, this is more for that kind of experimentation with modulated IR light. You could use this for the remote control. Honestly, I don't recommend it. I recommend getting an IR remote receiver instead because that'll actually do like the demodulation for you but and filtering for you. This is more for like science experimentation where you want to mess with IR light. Okay, and start the show tonight. So as you, lady, or our team, our customers, everybody who makes this video is... The IR receiver board. So that goes along with the IR demodulator. This board is specifically designed for people who want to do infrared remote projects. You can see like, you know, you press a button and it's like, I've received this code. So we sell in the store like little breadboard friendly infrared receivers. The problem is that you can't mount them easily and you have these like little thin legs that you then have to solder wires to. What's great about this is that you can plug in two millimeter JST connector and then you could plug into a board and you can see there's like the wiring is very simple. Another thing that's nice is there's a little red signal indicator LED to let you know that it's received signal and there's two receivers on there that you can select between depending on whether you want horizontal or vertical coverage. So if you go to the overhead, I can have a prototype here. It's green, but otherwise it's the same chip. So the first thing is... Oh, that's really bright. So let me put off that for a moment. Okay. First off, there's two receivers. There's a vertical and a horizontal and that's because maybe you want to have something that's like edge mounted and you want to have it pointing out or something flat against the wall and you want the signal to have as much coverage on the horizontal plane. So between these two, you obviously don't get coverage on the back. Although this one does have a little notch and like this is translucent. So you could... You probably could get some signal even if it was coming from the back. There's a switch to select which one you want to use. You can't connect them together because if they have different signals, they will fight each other. And so you have to select which one you prefer. But on the final version, oh, if you go to this photo...  On the back, you see this is IRH-IRV. If you want, you can get the individual signals from each one. If you have two infrared inputs on your microcontroller, as well as the signal, which is the selected output. And then... Okay, so can you go to the red again? I forgot, I had a prototype. And then another nice thing. Let's make this less bright. As you can see, when you send messages, the signal LED goes off, lets you know it was received. And then I just have a little example code here. What's the max distance for IR? I'd say up to 25 meters if you're lucky. It kind of actually depends on the transmitter, not the receiver, right? The receiver will, any signal you get, it'll work. And this will probably work about 10 meters away at the most. Maybe like, you know, it's best before 10 feet. It's meant to be like a room remote. But we have an IR transmitter dongle that we sell. And you know, it's very high power. And if you use it, yeah, you'll definitely get like 100 feet plus, no problem. Okay, so this one, as we press each code, each code is being decoded.  It has to go into my controller that has, that has an infrared receiver. So in this case, I'm using CircuitPython. Arduino also has IR receiving. Just make sure that you use the right pan and the right library. You have to decode it. Like this is in any C remote. So this board doesn't do any of that like, oh, I have decoded it. And to also tell you what the protocol is, it just sends the bit stream out. And then your microcontroller or microcomputer will have to actually convert that into which code and which button was pressed. All right. And that is new. All right. Don't forget you can get some of this stuff here. Springy's code. We're going to answer questions. I have some lined up, but first we're going to do some top secret. Okay. Oh, it's in the vault. Trim you on. Okay. So we got some more Trinkies being designed. So this was a request from Bill Binko at AT makers. So this is a TRS Trinkie. And the thing that he wanted was basically a USB adapter that would connect to a TRS 3.5 millimeter audio jack but did not have one pin connected to ground or power. It's like every pad on the audio connector was a GPI or analog input because this connector format is used for different accessibility tools and they have different pinouts. And so you want to be able to dynamically decide based on the code which is the input pin, which is the output pin, which one's grounded, which one's power. So I just, it's got a samd21 and a neopixel. And then every pin on that TRS plus the two switches again goes to different GPIO and then you can read them all. And then to make it mechanically stable, it's got a USB-A through-hole connector. And then we're looking at this like cool Windows 10 HID RGB LED array like protocol that they've come up with. And we're like, oh, that's basically like neopixels. So it'd be cool to have like a USB HID to neopixel converter. So it's a little pixel Trinkie that you could use also with Python or you could program in Arduino. It could be standalone running and it just gets five volts. There's a level shifter and it can control two strands of neopixels or one strand of dot stars because we use two pins. And the samd21, you think of it as a small chip, but it's got 32K of RAM in Arduino. You can drive like 10,000 LEDs if you wanted to. So maybe we'll make a little USB interface code so you can write pixel data from any application and we'll just like pipe it out very easily. And then finally, a lot of people are like, hey, can you make some of these Trinkies in USB-C? But I'd have to find a plug that's a USB-C plug and also mechanically stable like the USB-A plug. So I kind of made a breakout, hopefully this connector that we found on the Great Search last week. So watch that video. We'll work and it'll be mechanically stable and we'll use it to make some USB-C Trinkies. Best top secret. Yeah, it is. Okay, we're going to roll right into questions and then we are going to bounce to try to get out of here. Yeah, thanks everybody. Yeah, all right. So question Lady Aida. The first one is, you did the max distance for IR. Could you compare the floppy disk archiver and the emulator prototype with the release Adafruit floppy feather wing with 34-pin IDC connector? The floppy feather wing is kind of like a very simple board that's just, you know, you can run any code on it but it doesn't have buttons and a TFT. It doesn't have like, it doesn't have a level shifter. It can't emulate because it's set up for only writing to disk drive but it's basically for like floppy experimentation whereas the floppy board is kind of an all-in-one. You can do anything with it. It's like a multi-tool for floppy. Okay, next. Is it possible to keep the lithium ion batteries at the same time to make the milliamp hours bigger or larger? You can by the clever use of chemistry. One thing you can do is depending on the anode chemistry you can have it be a 4.3 volt. Or 4.4 volt battery I think they get up to depending on the chemistry used and that will just give you more voltage. So then when you buck it down using the RT6160A you'll get a little bit more capability. In general, it depends on the quality of the battery. You know, some batteries are high density. Tends to be the 18650 size because that's kind of where like a lot of the technologies is happening because they're used for making battery packs for like scooters and cars and you know every other kind of electric bicycles and all that good stuff. So there is sometimes variation based on the size but not from live polys as much. Those are kind of like the sizes very much related to the capacity. Okay, and let me see if there's any more because we had them lined up but I think that might be it. Thanks for helping us get out of here late tonight. Thanks everybody. Yeah, I think that is it. We still got a lot done. Yeah, we did. There is. That's how we're getting stuff done. We're cloning ourselves. So we'll see everybody next week. Thanks so much. Don't forget the code is springy. Okay. This has been an Adafruit production. It is your moment of zener. Bye everybody.


My name is So-young and I'm a PhD student in civil and environmental engineering. I think I can share my unique experience as a student doing energy research here at Stanford. The thing that I like the most is that you can actually do the very interdisciplinary study. For example, my research topic is actually to study how to catalyze more investment capital, especially private investment capitals, to promote the clean energy innovation and also combating climate change. And as you see, this requires a lot of different academic disciplines, like for example, economics, finance, public policy and environmental engineering. And I've been getting a great support from faculties and professors across the entire campus. And you can actually take the courses that are actually built to be interdisciplinary. So I really want to share more about my experience and my own resources after this talk, but to give you a brief flavor of what I do as an interdisciplinary researcher here at Stanford, I'm going to show you my recent paper that analyzed market performance of low-carbon investing. So in other words, we analyzed whether investors in the capital market actually earns extra return, extra risk-adjusted return by investing in the firms that are emitting less carbon emissions. And I think Professor Berger had already made a great start for me instead, because this is a very important topic. And what Professor Berger and others studied he mentioned in his speech is great because they actually built one more layer of consensus on what we should do to combat climate change, because in 2000, we affirmed that the climate change is actually happening and this is man-made. And thanks to Professor Berger's study and others, we also know now that climate change will have profound impact on the functioning of a human society and also academic economic productivity. But what we don't have as a consensus is market performance, like saying what does that mean in the market to manage climate change? There are still today a very active debate in terms of theory and also in terms of empirical evidence that the links between the environmental and market performance are very mixed. So this is a very important topic. But what we achieved recently is at the Paris Agreement, they actually highlight this is very important to put the finance and public policy in this area as well. Like they highlight we need a consistent flow of a capital to combat climate change. And Alicia already gave the number, but the international energy agency gave like a bigger number that project, the world will require 53 trillion US dollars in cumulative term by 2035 to meet the goals that was agreed by Paris Agreement. But then if you see the scale, this cannot be covered by a few value or mission-oriented investors. We really need to change the entire market to move forward. But if you see the markets today, the capital markets today, there are only a few investors who are actually including the environmental factors into their investment criteria and try to align their returns with their investment portfolio, the non-traditional financial objectives such as environment. So majority of the investors remains resisting to manage the climate change because they think that managing climate change may lead to the suboptimal decision. So this actually leads to our fundamental question for our research that why investors think that being green is a suboptimal decision. And we think that investors really need a better understanding of how the market evaluates the firm's environmental actions. So this study actually provides a clear empirical evidence in order to clarify the relationship between firm's environmental actions and financial performance. But before going into this, I mean, I'm going to give you a lot of numbers and technical terms and everything, but you know, think about yourself. You know, if you are the MBA and you are planning to be an investment manager after this, or if you are just investing your own portfolio, and then, you know, if you are able to see considering those environmental factors can actually give you the actual return, then this will be very, very interesting outcomes. So what we really try to do is bring like people like you to really make your investment behavior to change. And yeah. So we set the four research questions, which are sequential. First, we just ask like whether this low carbon investing actually gives you the actual return. And the second question we ask is if there is any additional returns, is that just for the benefit of high risk, high return kind of investment strategy? Or do we actually find something extra like abnormal return that we call alpha? And the third question is then, you know, we really want to know what does that mean by investing in those carbon-efficient firms? And the fourth is we really want to have robustness on our observation as well. So the methodology that we use is coming from the financial economics. First, we use the portfolio analysis. We build a portfolio we call efficient minus inefficient portfolio. We call EMI portfolio for short. You can really simply think about you are actually changing your investment strategy that you are selling out your carbon-efficient firm stock and buying your carbon-efficient stocks. And you are putting no extra cost to change your investment strategy. And we track the performance of this EMI portfolio to see whether changing your investment strategy will really give you the extra returns. And then, you know, what you really expect as an investment manager or just individual investors is that you don't want to take extra returns to get extra, like you don't want to take extra risk to get extra returns. You really want to find the alpha. So we try to, we use the asset pricing model to price the whether this extra return can be explained by risk factors that is well known now at the worst and everything. And then we run the regression analysis to examine the relationship between firms' characteristics and carbon efficiency. And the robustness, we were running a lot of our correlation tests as well. So our data was 736 U.S. firms from 2005 to 2015. And our data set was very unique. We merged four database, two costs. They collect the absolute greenhouse gas emission data of each firm in their data set, which consists of 13,000 firms in the entire world. And the MSCI, they not only collect the environmental data, but they also provide the ratings on their ESG, environmental, social, and government's performance. And Compute Set and CRSV is well-known data set for very typical financial analysis, such as like a stock price, returns, and financial variables. So the main findings we have is like from the first portfolio analysis, we actually find our EMI portfolio exhibit large, positive, and cumulative return after 2009. So this is very interesting. I mean, there are many more ways to build the EMI portfolio, but I will show you just one simple case of EMI portfolio construction. But if you see the upper table, this is average return on EMI portfolio, you can definitely do the mess, like carbon-efficient firm stock actually outperform carbon-inefficient firm stock. But if you go see the later period after 2009, the difference become larger and also statistically significant. This is a very interesting result. If you see the cumulative return on the EMI portfolio, you can definitely see the cumulative return going upwards scale after 2009. The red line that I drew on the figure is September 2009, 2008, when Lehman Brothers supplied their bankruptcy. So this is a very interesting trend that we find. And we also try to talk about more about like what investors really consider. They really find the high-sharp ratio, which means you get extra risk factors to return for one unit of volatility that you have. So if you see, I'm going to just point out this sharp ratio in the later period, that all the EMI portfolio have that highest sharp ratio compared to other factor mimicking portfolio, which is very interesting for the investors as well. And now we want to find whether like where this extra return is coming from, whether it's from alpha or it's a bad time. And we actually find this investment strategy is actually giving you the abnormal return, and this is annualized to 3.5 to 5 per percent per year, which is huge for the investment managers. And this is very typical GRS test. What we do is we run, we regress the extra return on our EMI portfolio on other well-known risk factors. And if we find the alpha is positive and highly significant, that means there's something else that can explain our extra return than the other risk factors. And our statistical findings actually shows that yes, there are something more, and this is huge. And then we also find what does it mean, you know, investing in those low carbon companies. And we find that low carbon companies tend to be a good firms in terms of financial performance and also corporate governance. So you are not only investing for the extra returns, but you are actually investing in the good firms. So I mean, we cannot really firmly say by just five years of observation that, you know, carbon efficiency can be a good factor, but actually this can be a good signal that you want to find the good firms and also look for some higher risk adjusted returns. But what we really care about is also the robustness of our observation. So we tested some other macroeconomic factors such as energy market prices or unconventional monetary policy after 2009 financial crisis may affect this trend, but actually we find that our observation is very robust, apart from those changes in the market. So I'm going to fast forward it. We think that this is very important because if you are an investor, you really figure out whether managing this climate change is actually extra financial or financial itself. So because if it is extra financial, then you might bleach your fiduciary obligation by investing in those carbon efficient firms, but otherwise, then you can really align your own goals and your own return, your investment portfolios with the combating climate change goals. For the policy makers, you really need to figure out whether this is giving you extra negative or positive externality and be able to design the new policy that can really allocate the capital space on the carbon efficiency. So the contribution of this paper is to clarify the risk and return relationship in low carbon investing. Like previous studies were only asking whether it pays to be green, but for the investors to move, to change their behaviors, they need more. They need to know like how and when and why they're getting paid more by investing in those firms. So we are giving academic evidence to not only the academia, but also the investors that you are actually getting market incentives on considering the environment factors in your investment portfolio. And this clarification will really catalyze more investment in combating climate change. So I know it is very, very technically heavy, but I usually spend an hour to explain the entire thing, but you are able to pull out more details on the full report that you can find from that link. And also, you can always email me to ask questions about this paper or anything about the energy research or energy finance. Thank you.


Hey, what's up guys, welcome to our trending reviews. Now this is the Keemaphone G100-1 wireless microphones.  This is a completely wireless dual set microphone transmitter and receiver set. Now this comes in about 50 pounds on Amazon, which is an awesome price for a wireless set of microphones here that you can use with all your cameras, your phones, your tablets, computers, whatever you want. And I'm gonna show you some audio samples as well to see how good this sounds. So let's just get straight into it. All right guys, so let's go ahead and open the box. So this is a nice hard fabric carry case. Let's go ahead and take a look inside. So just in the top section, you have a few accessories. Let me go ahead and pull these up. You have a dual micro USB charger. So this comes with micro USB charging on each of the transmitter and receiver headsets for the microphones. You also have a wire splitter. So this is a 3.5 millimeter wire splitter adapter for phones and tablets and laptops. So you can also listen to your headphones while connecting the receiver through the microphone section on the other end. Then you also have a couple of wind sleeves and then also a 6.35 millimeter adapter for power amplifiers, audio mixers and outdoor speakers as well. You also have a user guide just to give you some instructions to get up and running. Then you have the actual microphones themselves. So this is the transmitter there. You can see it comes with this very long adjustable gooseneck. You have the condenser mic right there at the end. So if I just zoom in a little bit, there you go. It has a couple of buttons there.  But then you also have a little clip for the headband which I'll show you in a second. Then you also have the receiver. So this is also a 3.5 millimeter receiver there. You've got the charging port and the on off button there and that's the only thing there. So I will connect that in a second. The last thing that comes with this is the adjustable headband. So it's quite flexible. It's very lightweight, pretty much weighs nothing. So you can clip this on top of your head which I'll showcase in a second.  Like so. So I'm gonna clip this into place. There we go. And now this is ready to put on top of my head and then I can start using. Now to pair this, you literally have to turn this on both of the devices and because they're right next to each other, it's gonna connect within two seconds or three seconds. You'll see a flashing blue light for it when it's actually trying to pick the connection from each other and then a solid blue light when it's connected. So I'm gonna turn the both on and then you can actually see how quickly they connect to each other. So right, so I'm gonna turn them both on now. Blinking. And there you go. They've both, I've got a solid blue light and now it's connected. So that's pretty much everything in the box there. It's completely wireless so you don't get any wired lavalier mic with it. It's an automatic pairing. So after the first time you've connected it with each other, it will always be connected to each other the next time you use it. And the great thing about it is that you can charge both of these devices simultaneously with the dual micro USB cable that comes with it. Now you get approximately six to eight hours of usage and it gives you a full battery within three to four hours of charging. It is waterproof and sweat proof on the gooseneck and the condenser on the transmitter. But the actual microphones themselves, the transmitter and receiver devices here, they are not actually waterproof at all. So they can't be exposed to any type of water. So that's everything that comes with this. Let's go ahead and give you some sound test samples. All right guys, so as you saw, it connects very quickly. It's 2.4G wireless and it's got an awesome sound quality on it for the price that you're paying. So now that it's all connected, I'm gonna go ahead and give you some sample audio clips. So currently my audio is coming from a shotgun microphone just above my head here, which is going into an audio mixer called the Mix Pretty 3. But I'm gonna now switch over to the audio directly from just my DSLR camera here. So now I'll switch, the camera's only two meters away, but still it's quite echoey and it's hard to hear. Now what I'm gonna do is I'm gonna connect this receiver onto the microphone port onto my camera there and I'll start speaking into the transmitter here. So let me go ahead and switch that over. Okay guys, I've now switched over and I'm using the ChemoPhone G100 directly on the microphone here. So as you can see, massive difference between a no microphone on the camera and using this wireless microphone on the camera. So no matter where I'm moving around, I have the freedom of movement with this headband. It's very lightweight. I can't feel like there's anything on my head and it's perfect for, even when you're doing fitness classes, if you're jumping arounds, I can see this pretty much staying solid on your head and it won't really fall off. Now this is adjustable as well, so if you're too close, you're too far. If you have this connected to speakers, then obviously you'll be able to hear how good or bad the audio is so you can adjust this accordingly. Now the one thing I really like about this is the compatibility of using this with mobile phones. So if you're the type of person that goes out vlogging and you want better audio for all the videos that you're recording, then this is the perfect choice for you. Now my Google Pixel 4 doesn't have a headphone jack, but I have a USB-C to 3.5 millimeter headphone adapter, which I'll be plugging into my phone. And as I've shown you from the unboxing, you take the Y-splitter cable and you connect that to your headphone port. So whether you have a headphone jack on your phone or not, that's absolutely fine, just as long as you can connect this some way possible. Now you have two ends. They have an image on each end. One shows headphones and the other one shows a picture of a microphone on there. So you take the receiver of the keyboard phone and connect it to the microphone port on this and then you'll get the option in your phone's camera, obviously depending on the type of phone you have to switch over to using an external microphone. So now what I'm gonna do is go ahead and switch the video coming from my phone instead of my camera. So the video quality will change a little bit, but I'm gonna show you that how easy it is to connect with your phone as well and get that up and running and see the quality of the audio coming from that as well. All right guys, so I'm recording directly off of my Google Pixel 4. I've not connected the microphone yet. I'm just using the raw audio coming from the actual phone itself from the internal microphone. So now I'm gonna go ahead and switch from the settings of my camera app to use the external mic, which is the chemo phone one. All right guys, so now I've switched over to use the chemo phone microphone. Let me know what you guys think of the big difference in the audio quality. So obviously this is adjustable and I can move this closer or further away. So now the next thing I want to do is give you a comparison of what this sounds like when I take it outdoors. So indoors, I can definitely hear the difference. Now outdoors, obviously if it's a busy environment it's quite noisy or it's a little bit windy. I'm gonna give you a sample of using this in that type of condition. So I also want to record a quick clip of putting the wind sleeve on as well and give you a comparison to see how much of the wind is taken out of the actual audio. So let's go ahead and switch over to that. Hey, what's up guys? So I'm just outdoors. It's quite cold and it's quite windy. Now I'm using the internal microphone on the phone. So I'm gonna switch over and start using this one. So let me see if you can tell the difference because I wanted to get an idea of how windy it is coming through the internal mic on my Google Pixel 4. All right guys, so now I've switched over using the chemo phone microphone. It is still quite windy. Just want to see if you guys can hear the wind blowing through this condenser and to see if there is a massive difference between the audio levels. I've played this back a couple of times as well. I can tell the massive difference in the audio is so much more clear. It's crisp with the clarity in the audio coming through. Regardless of it being a little bit windy, it's so much better. So what I'm gonna do is I'm gonna put the little sleeve on, this little wind sleeve and see if that makes an even better difference. All right, so it's starting to rain a tiny bit. It's just drizzling but I have the wind sleeve on. So can you guys hear the difference with the wind being taken out of the audio? Or can you still hear it just wheezing in the backgrounds? Now I've played this back as well and in terms of the actual wind protection there, I think it does give you possibly maybe about 20% better clarity with the protection and the audio is just so much easier if you're gonna go out and you're gonna start recording videos with using vlogs or if you wanna use this to do outdoor fitness sessions or anything like that. Then for me, I think it's just done a great job. All right, guys, there you have it. So hopefully you found that review very useful and you found those audio quality sample and comparisons really useful as well. Now in overall conclusion from my side, I think this is a excellent microphone to have, especially if you're running classes or workshops and you wanna connect this to external speakers or amplifiers. I think this is gonna do a very good job. You can also use this as a handheld microphone as well. So technically you don't need to use the headband if you just take it off, you can just use it as a mic and hold it and if you wanna run business meetings with this, then absolutely that will do a great job as well. So it just comes under 50 pounds and I think it's a complete bargain. I'll leave a link in the description below of where you can purchase this as well. And if you're into vlogging, then I think this is a great option as well. So it's done a great job recording audio from very noisy and windy outdoor conditions as well. So that's a huge plus from me. So if there's anything else you wanna know, then do drop a comment below. Otherwise I hope you found that video useful. If you did, I hope you hit that thumbs up button. I hope you subscribe so I've got a lot more cool tech reviews coming out very soon and I'll catch you guys at the next one. Take care.


In this brief video, I'm going to show you how to generate citations in two search platforms. First, we'll use the catalog search, which limits searching to resources that the UNM University Libraries has access to. Then, we'll switch to the WorldCat discovery system, which searches libraries worldwide. All right, so I'm starting at the Libraries homepage at library.unm.edu. In the default catalog search box, you can see it's selected here in dark gray. I'm going to do a simple search for the keyword happiness, just popping it in this box. All right, so now I'm in the results page, and I need to click on one of the titles in order to get the screen where I can generate citations. So I'm just going to click on this first result. All right, so now I'm in the detailed record. Over on the right, you'll see a tools list, and one of those tools is labeled site. Click on site, and it will generate automatic citations for a number of writing styles. I can sort of see scrolling through them. We've got APA there, MLA is another big one. Okay, something important to note here is that these auto citations, like this one right here, you're going to want to reference a style handbook like the Excelsior Owl. And that's where you can go. It's a resource where you can check your citations generated here against there to make sure that they're correct or adjust them as you need. But in any case, this is much easier than building a citation from scratch. Okay, so that's one way. I'm going to go back up to see the button library website. This is how I'll get back to our main page. Okay, so that was the first search platform. Now I'm going to switch over and let's look at the world cat discovery system. So from this homepage, underneath the catalog search box, there's a small link here listed world cat discovery. Click on this. Okay, so here we are. I'm going to just stick with our previous simple search for the keyword happiness. So I just have it there in that first box. That's great. And I'll click on search. All right, so it looks pretty similar to what we just saw. But the thing that you might note here is that you don't have to click on the title. There's actually a site button right over on the side here. I'm going to click on this. And now you might notice there's a drop down so you can click if you need APA or whatnot. Here's your citation that you could take as a starting point. And again, you see that they have their own proofread the citation warning. This process works similarly across many of our databases. And remember, the library is here to help. If you have any questions about this or anything related to library research, please get in touch with us. You can see a big link here on our homepage. Ask a librarian. Here you can find some contact information for us, phone numbers, text us, email us, find your subject librarian. And of course, you can always come in to one of our desks. Thanks for watching.

Asante sana. Thank you.
