Okay, so now we are ready for Hiba, and Hiba, I would ask you to introduce yourself, please. Thank you very much. Thank you, Christian. Hi, everyone. I am Hiba. I am from Palestine. At the moment I live in Gaza Strip. I received a master's degree in midwifery last year from the University of Aberdeen in Scotland. And now I am working as a clinical instructor at some local universities in Gaza, and also working as a clinical midwife at a maternity hospital in Gaza too. So, this presentation is part from my master thesis, and I am happy to be here and to participate in this conference, and hope that everyone will enjoy this presentation. I will start now with my presentation. It's about women's experiences of a childbirth in the Arab world, a systematic review of equalitative and quantitative evidence. Sorry. This picture was on the day of my graduation ceremony at the University of Aberdeen. I am the second one from the right. The first one from the right side, she's my first supervisor. Her name is Lucia de Ambroso, and the third one, she's Helen Bidford, my second supervisor. And the fourth one, she's Alice Gajal. She's the external examiner for my thesis, and I am pleased to tell you that I was honored to win her prize for the best in the free nursing research project at the College. Okay, so I will start with some introduction about the Arab world. The Arab world occupies a large geographical area which comprises 22 Arabic countries. In the Arab world, marriage is considered the gate to childbirth because it represents the only foundation within which childbirth is allowed, as well as that childbirth is viewed as the purpose of the marriage. Childbirth is a major life event and a special life story and emotional experience for women. Women's experiences and their stories of childbirth are therefore relevant in developing evidence-based care on individual subjective narratives. So, there is an urgent need for women's experiences to be incorporated into health services and health policies toward improving the quality of care in maternity services. Just a simple notice. I am sorry about what you're hearing from my background. I cannot stop this sound. It's from an open area and I am absolutely lost the room and you still can hear the sound. Anyway, there's a report from the United Nations. Okay, thank you. There's a United Nations report demonstrated as a substantial discrediting rate among Arab women in most countries except Iraq, Yemen, Palestine, which is my country, Sudan, Somalia, Mauritania and commerce. The total fertility rate remains over four live pair women reproductive age for these seven countries that I mentioned which indicates continuing high rates of fertility for some poor and rural areas. The geopolitical status at the Arab world nowadays is complex and challenging due to state of the crisis and armed conflict areas such as Iraq, Yemen, Syria, Palestine and Libya. So, these circumstances undermine the health system and cause emergency health situation because of the occupation, internal civil strife and political tension. There are comparatively fewer studies addressing satisfaction and exploring women's reported experiences as an outcome of maternity care in the Arab world compared to Europe and United Kingdom. Therefore, it has been worthwhile in this paper to focus on women's centered care during childbirth experience to develop recommendations towards influencing health professionals and policy to improve health systems and make real change. So, the aims and objectives from this paper was to addressing these two questions. The first one was what are women's views and experiences of the flavor birth when accessing delivery services in the Arab world? And the second question is what does the evidence suggest for policy and practice? The methods for this paper was a systematic review accompanied by a synthesis of the quantitative and the quantitative studies describing women's experiences in birth and labor in the Arab world. The elements of textual narratives and thematic synthesis methods was used to analyze the data from selected study. Also, my experience and reflections of my professional background was also incorporated for the result of this paper to support the interpretation of the data. Now for the findings. Eleventh studies were selected for the review, three quantitative and eight qualitative studies. From the analysis, there were two overarching themes where identified women's centered care and medicalization of childbirth. Medicalization of childbirth with unnecessary technologies can be viewed to exist in direct opposition to centered care delivery with culturally sensitive care where women are empowered and otherwise lead care in childbirth. For the first theme in this paper, the women's centered care in the papers, many women would have appreciated the feeling of control during the childbirth process. Women indicated their need for families' emotional support and their mother's attendance during labor. However, it is forbidden in most public hospitals and actually this is the policy in most Arabic countries. For the second theme, medicalization of childbirth, women experience a number of routine practices that were unnecessary, harmful, and non-indicated of procedures during labor and birth. Those involved induction, artificial rupture of the brain, continuous fetal heart rate, nurturing a frequent vagina examinations, and epizotomy, enema, and shaving. The humanization of childbirth were so important in terms of lack of respect, care, poor pain management, lack of necessary information from childbirth assistance, and lack of privacy. The medicalization of childbirth was observed in the widespread use of unnecessary procedures which affected negatively women's control in the childbirth process, except in terms of demonizing childbirth. In conflict areas and during wartime, such as on Gaza in December 2008 to January 2009, there was no safe place for childbirth, as reported by Wick and Hassan 2012, women in this area reported multiple barriers to accessing a suitable birth place. They reported no mere safe place for childbirth or access to thereby health birth attendants and fear of unknown about their families and their labor status during the constant sharing. This is reported by the woman from Gaza that the woman had facing the war in 2008-2009. In addition, there was the impossibility of knowing when and where the bombing would take place and so safety guarantees were impossible. The wives also reported trying to help laboring women with only simple and ill-prepared equipment. Now for the reflection of my experience in Gaza to support the result of this paper. In 2012, I was working in the largest governmental hospital it's called the Chiffa Hospital in Gaza Strip. The Ministry of Health in Palestine sought to employ midwives in maternity services with WHO, cooperation to build midwifery healthcare during training the midwives with the basic and advanced skills. Midwives in Gaza are authorized to manage low risk cases of laboring women during delivery care as defined by International Confederation of Widwives ACM. However, the midwives in Gaza are unable to order any procedure without reference to doctors in spite of WHO recommendations for midwifery healthcare in Palestine. Their severe pressure worked with high case loads. For example, during my work, there were more than 20 cases with only three midwives. Every shift, one physician and one obstetrician. Doctors request oxytocin infusion for most cases and physiognomy used routinely for most primigraphida. Some doctors use their previous experience and their old knowledge without guidance according to WHO recommendations and evidence-based practice to deal with the emergency. The women also are restricted in mobility and drinking during labor. Therefore, the midwives and the doctors actuated women's labor artificially by playing the paper. All women give birth in lighted homey position and I can say this is the only position the women can have tried birth in the public hospitals in Gaza. And companion support to attend labor is forbidden due to open area in labor world in which the patient's feet are separated by curtains or movable walls. However, it's allowed in the private health facilities to have social support during childbirth. The overall work results is insufficient with wifery support for every woman. To conclude, my experience in Gaza was relevant and consistent with the findings of this paper or this review. The medicalization of childbirth and using unnecessary harmful procedures in post-conflict region were also relevant to the two overarching themes identified in the results chapter. As a result, women's preferences are critical sources of knowledge to explore and consider in such situations. Now for the key conclusion. To counter the effects of intersecting lines of medicalization and technology power over women's experiences of childbirth in this context, health policy makers, decision makers, midwives and other health care professionals need to work with this available evidence of women's experiences and narrative account of childbirth to achieve high maternity quality care. The indications for practice. It's important to involve all stakeholders including midwives, maternity care professionals and women in efforts to improve character practice and also to eliminate unnecessary procedures. There's a need to develop policy in the Arab countries and update WHO recommendations with evidence on the subjective lived experiences of delivery and childbirth to achieve high maternity quality care and women's satisfaction. Also, the decision makers need to empower midwives in their community, either geographically or socially to be able to provide their care for marginal groups or in time of the crisis. Especially now, the situation in the Arab countries is not stable. Also, there's a need for planning for emergency care is essential by mapping the availability place of midwives providing them with basic medical equipment and medicine at home and any clinics in order to facilitate their care to women's needs during a childbirth. The future research. We need a future research to focus on somehow to support women and in supporting childbirth experiences forming a few points of skilled birth attendants and maternity care staff. A future study could also explore in more detail the challenges of providing evidence-based practice to reduce medicalization of childbirth in terms of legitimacy of subjective lived experiences. A future review and research would focus on whole childbirth experience including antenatal or intrapartum or postpartum period are recommended. A greater effort and evidence is also called for women's rights of safe birth a respectful healthcare and accessible and available access to care during complex and wartime. Now I just put some pictures was taken by Al Jazeera. This picture was in the last war the last, I can say, the last Israeli attack on Gaza in 2014 exactly in July 2014 the first picture is from the Shifa Hospital Maternity Unit During wartime we can expect 25 to 50 women over 24-hour period and also the medical supplies are running short due to ongoing Israeli offensive on Gaza another meaning Gaza is still under blockage by Israel so this blockage also limits the medical supplies and we have big chances in basic equipment. The second picture from Shifa Hospital too as the ambulance made its way to the hospital this lady called Hanan El Mahinfin continued to plead and was rushed to surgery where her baby care was delivered by a caesarean but unfortunately died at birth offered for her condition Hanan was not told the news of her daughter's death until a day after the surgery Hanan said, when they told me I felt like I couldn't breathe I wanted to cry but I was too tired I think this is the last picture Maryam joined it, 39 years old it's a mother of eight and now she's expecting her ninth child as I mentioned in the introduction the fertility rate in Gaza or in Palestine in general and in Gaza it's high I can say it's 4.6 baby women and this is the references now I can say, oh, I finished and now I am happy to hear for any questions or any comments Thank you very much Hiba for you Interesting presentation there was one question in the chat right in from Monika she asked if women's mothers are allowed during birth in the hospital Yes, actually this is a policy in the governmental and public hospital they cannot bear birth companies, mothers or any relatives because the area of the hospital with the leopard women is very crowded and if the hospital allowed for every woman to have hair relatives it would be more crowded so this is why they avoid this and I can say there's another reason there's another reason I think it's for cultural it's related to cultural beliefs some husbands maybe refuse to be to attend the childbirth maybe they are shy or something like that so maybe this is the I can say this is the reasons that's another question so I would like the answer was clear for everyone I hope the answer is clear they will ask if it's not clear so I ask our participants to put in more questions to Heber while our participants are in ah ok, Margaret is asking do all women go to hospital for birth or are there a birth at home? Ok, actually we have two systems we have public hospitals and private hospitals at the moment we don't have a home birth except for women she cannot go to the hospital and suddenly have birth at the home but till now we don't support the home birth in Gaza and I think this is bad but for my side I think it's good to support a home birth but to answer your question at the moment the women can have birth at a public hospital or a private hospital just ok, thanks Margaret ok so please put in other questions for Heber I would like to ask the question what is about the breastfeeding rates in your weekend? yeah ok, about breastfeeding Heber? yeah, sorry did you ask about breastfeeding? yeah, breastfeeding rates of breastfeeding yeah, the rate of breastfeeding in Palestine is actually high it's 96% yeah, it's considered high it's 96% that we have cultural beliefs about breastfeeding so if the mother at the beginning have or facing difficulties with breastfeeding her mother or her relatives will support her to breastfeed her baby ok, Akita is asking in the rate of caesarean sections in your region, your country ok, actually I don't have accurate person about caesarean section rates but I can say the normal vagina delivery is more than caesarean section and usually the women prefer vagina delivery and just for urgent reasons or accidental reasons the women prefer for CF but I am afraid I don't have accurate number so, but is it often in your experience or to women ask for CF? no, it's not often because we usually refer the women for normal childbirth but for some reasons for example, if the women have at the Bartam homerage or accidental homerage the lady should be referred to CF yeah, it's a good question are there any wife-led care units at all? in my country there is Norway it's called Norway it's a project supported by Norway it started last year to support the wife-led care unit in Gaza and it started just in one hospital it's in the Chippa Hospital because it's the largest hospital in Gaza and I think they started in this hospital because if this project succeeds in this hospital they will follow other hospitals with that project this unit actually just for low risk cases the midwives can can care with women with women low risk consider as low risk the women don't have any medical problems the wife can care with it without any interruption from the doctors or obstetricians the midwife in this unit don't use oxytocin don't use ebusutony and the midwife using birth deep exercise full exercise and they ask the women to choose which physician usually prefer to have childbirth but most women as I can see they choose light atomy position I think because they think because as they use to have childbirth by light atomy maybe they think this is the best position for them but we try to learn them that you can choose any position you like okay, thank you very much now see let's see if there are any more questions from our participants so what about the education of midwives in the Gaza are there enough possibilities to get well educated as a midwife in your region okay, we have two colleges teach midwifery programs the midwifery program in Gaza it's four years for example at my side I have a bachelor from the Islamic University of Gaza and my bachelor was four years I started a clinical training in the hospital from the second year and then so continued the training in third and fourth year then after graduating we have period called Eternalship period like 300 hours this period to make sure that I am good with wife after graduating and I cannot take the certificate without finishing this Eternalship period so in Gaza we have two program two midwifery programs in Gaza the first one was started in 2001 in College of Palestine called College of Palestine and the second one started in 2008 at the Islamic University of Gaza and also we have another program for midwife it's called Practical Midwife the midwife can be a practical midwife for two years it's called Diploma Midwife I think maybe the word Diploma is different for you because Diploma is known for certificate Diploma in Gaza means that the midwife has learned for two years to be a midwife and actually the practical midwife who has two years she can deal with women support women but for example she cannot provide help in a trial period just so she can help in both natal and natal units that's it what about midwife associations in Gaza how are you organized in your region? okay actually we don't have special organization for midwives in Gaza we have association called nursing association this nursing association can cover the midwife free issues just that so we don't have unit or organization special for midwives and I think this is a weak point for midwives in Gaza but for example if I need help in some issues I can go to this association or I can go to the ministry of health in Gaza I can see another question Christian how long do women stay in hospital after trial period okay for women for women has no much help there if the woman is pregnant she can stay for like 4 to 6 hours and the woman then after that ask to discharge for the multi-gravity the woman usually actually stay just for 2 to 4 hours and most I can say most women stay just for 2 to 3 hours after no much trial period but after if the woman has CS she should be stay at least for 2 days in the hospital and she can go home at 30 or 40 days and do midwives help women at home like visiting them at home in the first weeks after the birth and is it painful? yes we okay having trial period in public hospitals it's free no paid no money to pay by the families it's free but in the private hospitals it isn't free for the supporting women after they going to home yes we have community midwife the community with midwife working in the postnatal clinics and they have regular visits the midwives have regular visits to women's home to support women and to provide some health instructions about childbirth about caring baby caring herself after childbirth and so if the baby needs vaccines or something like that yes that's it so there is a question it's about how is the bonding and the skin to skin supported I am pleased to say that we support bonding and we support the skin to skin contact after childbirth directly we have this and before do this we ask women that we would like to to put your baby in your abdomen some women fears at the beginning some women's they used to have that and for the bonding I can say we have risk feeding at the first hour of childbirth most women risk feeding their baby because I said this is a catcher of news about risk feeding okay so I was going to ask you but you said that the units get really really busy sometimes and how do you cope but how do you cope with that when you're flooded with women Christine I like to hear the hear Eva do you hear us okay sorry Christine no problem Christine please put again the question Christine can you hear me can you hear me Eva Eva do you hear us no sorry what's your question sorry please repeat your question I think I had interruption in there disconnected internet just for a few seconds what did you ask sorry oh sorry I said you said in your presentation that the units often get very very busy how do you cope as a midwife with a sudden with lots of women coming in are you able to hear my staff name or I look at your house I thought you were coming I think please write type in the type in the question okay okay sorry I think I had disconnected internet just for a few seconds okay what's that question what are women's or our own experience of typical midwifery care in both the midwife with great and public hospital okay actually we need to study we need to do study and research about this point about experience of typically of typical midwifery care in both the midwife the unit and public hospital but I just can give you some highlights points about that I can say sometimes you find a woman satisfied about her childbirth if she had if she has sick childbirth without any complications and some women just dissatisfied about her childbirth if she's having complications or problems like family health care hospital home or these things but in general I can say it's maybe half-half yeah yeah I think I can say yeah it's maybe half-half that the woman sometimes satisfied about the rule of the midwife and the public hospital I think it depends I hope it is clear for your question thank you so please put in other questions for Hiba fantastic guest from the Gaza Strip I would like yeah continue question continue continue what is interesting for me while I'm googling I just found midwives with the organization midwives for peace which is a grassroots organization do you know about it sorry I didn't for your question the organization midwives for peace organization yeah midwives for peace I have no idea about this actually no problem okay so we have another sorry about that yeah we have another question how do you cope with the extremely busy unit as you said can be up to 40 to 50 women in 24 hours yeah yeah thank you for this question it's good question actually it's very overall we try to manage we try if need help we can call midwives from other units or midwives who was in the call we try to organize the work with the women for example we just take the women so we have words as you know we have antenatal words interpartum words so usually the antenatal words I mean the antenatal words the women with who they are in the first stage word I mean who they are in the first stage of labor they are in antenatal word this word department or this word is usually busy so we just take the women to the labor room who are nearly to be fully or the women for example 7 to 8 c.m. they dated this is one of the methods just to organize the labor room and to organize the first stage word and I mentioned before sometimes for just away the women just stay after childbirth from 2 to 4 hours so after 2 or 4 hours they are there to space for another woman so by this simple method we can just organize and control this overload and the pressure work and also the situations and the obstetrician they help us in the high risk word so to reduce this overload pressure work so we have another question from Julia who is asking what is the midwife to patient ratio ok I know internationally it should be midwife one midwife per one woman but in Gaza I can say one midwife per 7 to 10 midwives sorry one midwife to 7 to 10 patients in maternity departments in Interabarta and the alternator and maybe you think that we have shortage of mid-flood wife yes we have shortage but also we have graduated midwives in Gaza but because of the clinic status of the of the Ministry of Health the Ministry of Health cannot employ more and more midwives because they have problems with their funds so they just they both for example and that we have actually two midwives per every shift sometimes two or sometimes three labor room we have three midwives per every shift first stage work personal work obstetric ICU we have obstetric ICU gynecological department we have just two midwives per every shift so yes this is what I mean when I said overload work do you have a separate assessment unit or this included with the same unit sorry can I ask you what do you need what do you need with a separate assessment unit is that you need the assessment for the midwives the midwives paper that what do you mean initial form call do you have a separate assessment unit or assessment of presenting women yes we have initial assessment in the reception if the women for example come with labor pain they will come to the admission department and they their women their midwives in the admission department will assist the lady and if the lady in labor if the lady has cervical irritation more than 4 cm more than 4 to 5 cm they will admitted to the first stage work this is what I mean this is what I have but is that what do you mean with the initial assessment about you and so I I saw the sorry I'm afraid we are at the end of our time I would like to thank you very very much for your input and for answering the questions I wish you everything the best for your for your work on a very hard situation and all the best for you and for your family thank you very much to be part of this and I want to be thankful also that I had a chance to get to know to you thank you to everybody here in this room now I will give over to Sarah once again everything good from Austria thank you very much brilliant Christian thank you so much for that I'm just going to do a little bit of housekeeping and save a chat and you are welcome to pop off and have a 10 minute break and stretch your legs while I tidy up this room we will start again at the hour thank you


Joe, it's time for John Park's workshop. It's me, I'm John Park, and here I am in my workshop. We're gonna look at a couple of projects today. I've got a continuation of last week's project. It's in a much more completed state, just about ready to start working on a learn guide for that. That's our Touch Deck project. And then I'm gonna introduce you to the next thing, which is this Raspberry Pi 400, which is that cool all-in-one keyboard and computer Raspberry Pi, synthesizer controller using some analog knobs, kind of a continuation of the JP's product, pick of the week from Tuesday. It's all somehow interconnected. Let's see. I wanna first of all say thank you for joining me. And if you're wondering where all the chatting is happening, look, this is it right here. Oh, geez, I need my glasses. It's in Discord. If you check out the Discord, it's Adafruit's Discord at adafruit.it slash discord. Hey, where did I go? That was weird. I clicked a thing and I went to another screen. Hmm, strange things for our foot with my computer. Maybe I should have put on my glasses sooner. Could you see me that whole time? Yeah, the question is this a workshop or the virtual workshop? Today, it's the real workshop. Look, there's no retro reflective green screen, blue screen here today. There's a rolled up one back there. And then I've got a boom arm there. I was thinking of setting it up for today. It would have been good for some of the demo that I'm gonna show you inside of Rhino and Grasshopper, but alas, I didn't have time to get it all set up because I was working on projects. So if you are joining us over in YouTube, hello, Eric and MoondogIT and Connor McCarder. Nice to see you all. If you're over on Facebook or Twitch or any of the other services, I'm sorry, I am not keeping an eye on those chats. I only have so much attention to spread across things. Hey, Melaku, Yosef, nice to see you. And yes, I wanna say hi to these people over here in our Discord chat. So Andy and Steve and Hugo and Sea Grover and Susan. Mr. Certainly, thanks for coming by. Gary-Z, hello. All right, so let's get into some stuff here. Let me see if I can safely remove that without changing my camera views. Hey, that time it worked, weird. First thing I'll mention is the jobs board. If you are looking to share your resume because you're looking for some contract work or full-time work or part-time work, head on over to jobs.adafruit.com. That's the thing right there. You can see it. This is if you head to the available for hire section, you'll see some people looking to work in Canada, in Iran, in Buffalo, New York, in Spain, Atlanta, Georgia, Colorado, people all over the place who have skills on offer. So if you're looking to hire someone, this is a great place to look. You can see we've got a lot of people with engineering skills, embedded development, inventors, art and design, retail, all kinds of positions on offer there. So go check out jobs.adafruit.com. It's totally free. It's free for you to go and check it out. It's free for you to post a position. It's free for you to post your resume. Free, free, free. So why not use it? Use it, I say. All right, let's see. Did you know I do a show on Tuesdays as well at this same time? And it's my product pick of the week show where I take some product. I've been doing a lot of STEMA QT boards and I check it out. I get into a little more depth with it. I go beyond the initial surface level of it and actually dive in and build a project with it, usually some kind of a demo project. And I get to learn a little bit about it, how to usually, how to use it in circuit Python or in some cases in Arduino, sometimes both. And this is what it looks like. It changes every week. So it doesn't always look like that, but that's what this most recent one was. And that little board there, that PCF8951, actually I got that wrong, didn't I? It's the 8591, isn't it? Yeah, I got that totally wrong. Ignore that graphic, but instead, I'll give you a little recap. It is the PCF8591 and it is an 8-bit ADC and 8-bit DAC on a board with STEMA QT. Got a cyber deck plugged into the GPIO pins of this Raspberry Pi 400. This Raspberry Pi is running a little Python program that uses the circuit Python library for this board. It reads all four of the analog inputs. What I'm doing is tracking the first knob here for the X position, the vertical line here with this second knob. Third one we saw, that's changing the hue. And then the last one is brightness. So you'll find I can get that pretty zorching bright there or drop it, drop it down way, way low or all the way off. It is the PCF8591, 8-bit ADC and DAC in STEMA QT format. Right, so that was the product pick of the week and if you didn't know, during that time slot when I do the show, you can get 50% off or sometimes it's a different amount, but this one and a lot of them have been 50% off. So you can get the board for like $3.20 or something like that. We have a limit of 10 at that discount price, no resellers, but we want individuals to grab stuff and if they want, if they have big plans and are thinking of doing a project that has lots of DACs or ADCs in this case or both, that's a good board to grab. In fact, the board has four address pins or four address has jumpers so you can have four different I squared C addresses. So you can use them all, you can chain them which means you can have 32 potentiometers or faders or whatever on your project. Even if your project board doesn't have any analog input at all, which is great. Very cool way to set up some eight bit, only 256 levels, but eight bit ADC interface. It's a great board. All right, let's see, questions in the chat. Let me bring up the chat. That's not the chat, that's the chat. Recap because of the capacitors. Oh, the puns have started. Never ended really high, Todd Bott. Nice to see you. You got a Cappy capacitor, you did. Hey, that's a cool, kind of a cool segue actually into this project I'm working on. So I started this last week and what I'll do is jump over to this view here. I know we're gonna get some reflections just because I have a lot of lights in the studio here. So let me take, I'm gonna remove the Discord view there for a moment but I'm gonna bring it back at some point. And one of the things I wanna show you, actually let me go to a small view of me there. One of the things I wanna show you with this, so this board is, what are we looking at? It is the Feather RP2040. So this is that same chip that if you can see it there, there's a little Raspberry Pi logo right there on that chip. And that's cause this is the same chip that's on the Pico. We now have this Feather RP2040 and it gives us USB-C, which is kind of nice. It gives us battery charging and a connector for powering over a LiPo or other three volt-ish battery source. We have a Stem-AQT connector on there so we can plug it right into something like that. Analog DAC, ADC and DAC board. What else do we have? We have some very nicely marked silk screen of your pinout on the top of the board and in fact, when we're went one better and put different pinout information but pinout information on the top and the bottom. So this just tells you kind of the raw GPIO names of the pins that are available here and then you get the sort of Feather pins named so you can tell what your I squared C pins, battery pin, all these analog pins and so on and so forth. Got a reset button on there too and a NeoPixel for display. So really cool board and I'm using it in this project. We started this project last week by plugging it into a FeatherWing. So FeatherWings as you probably know are the boards that we can plug Feathers into or on top of Feathers to extend their capabilities. So in this case, this Feather RP2040 plugs right into the back of this TFT display. Three to half inch, it's 480 by 320 pixels and it is a touchscreen display. I've still got the protective film on this one because I'm still building this one but that is what's sitting inside of here. And one of the things I'll talk about is the case design. I started working on that last week. I'll show you just a kind of quick step through of how I built it. This is an earlier iteration. I kind of changed some of these whole sizes a bit but you can see the board kind of sets in there and we have space for everything to fit and still get to reset buttons and things like that. And then I have a case top that goes on top. So that's what's sitting here and then I've got some M2.5 screws running through and I put some nice little rubber feet on there so it doesn't slide around. And what this is doing is it's plugged in over USB-C and it is acting as a USB HID device. So that's a human interface device. It's acting like a keyboard and it can do keyboard shortcuts like pressing a key or a sequence of keys, control shift four, that sort of thing. It can send consumer control which is like volume up, volume down for system wide and it can also do, we have in the circuit Python HID layout library, the ability to type a whole phrase in can be, I don't know what the limits are but it's just a quote, a whole bunch of stuff you wanna type and it'll type out a whole declaration of independence if you wanted to. The reason that's important is because one of the ways I'm gonna use this is as a emoji shortcut machine for Discord and the way Discord and some other chat services work is they have a format where you type in colon, smile, colon and that'll give you a smiley face. Another thing I'm using it for, you've seen me do a bunch of different iterations of this sort of thing, but this one I may keep this around in this use and extend what I've done before for camera switching and one of the original ideas behind this was the stream deck, which is used by a lot of people who live stream to do camera switching types of things as well as other managing of social and chat functions. And what you'll see right here is I've got these cam ABC, those are the picture in picture cameras. So let me see here, I'm switching among the three cameras there and I can also switch, let's go back to that one there. Let me take myself off of there. And then the main cameras. So that's my main workshop camera, that's my down shooter on the work bench and that's my down shooter right here. So you can see, can get a little confusing working on this stuff while streaming live because hey, I'm trying to, and I don't have a shortcut yet for that little view right there of just me. So those are actually just typing 1, 2, 3, 4, 5, 6 and I just have those shortcuts set up inside of Wirecast which is what I'm using in broadcast as the keys that get hit when I wanna switch camera views. Now, if I go back, let's go back to the full view of this and I can get rid of the little mini view there. If, so one of the really cool things is this was, by the way, I wanna give credit where credit's due, I forgot to mention this last week, Matambale in our chat offered a suggestion to me a few weeks ago about doing this type of a touch thing in order to type Greek and math symbols and that's one aspect of this that I'm gonna be creating, I haven't built that layer set yet and Todd Bot also in our chat suggested doing a stream deck type of clone so those ideas have come together and we were able to secure the help of FOMI guy, our very own FOMI guy in the Circa Python development community has created some really great updates to some of the libraries that are making all of this work faster and better than ever as well as the code and the ability to abstract our button functions and icons and button positions from the main code so it's fairly easy to maintain an update and even share layer sets with people. So what am I talking about layer sets? Well, this is not restricted to just this set of 12 buttons that I have here. I created some little icons here so that we can move to the next layer, to the previous layer or to the home layer. So if I go to the home layer that's always gonna bring me to whichever one I designate as the first layer set. In this case, I've got it set as some YouTube controls. So I won't touch these because they'll break stuff since I'm not in YouTube right now but it does things like play pause, the five second jump or go back with the rewind and fast forward. Next we'll go to the next video, previous we'll go to the previous video if you're inside of a playlist which has a previous video, volume up down. Those are media controls so those will change it system-wide regardless of which software you're using. Full screen, that's some key combo. I forget maybe just control F or shift F. Slow and fast, these increase or decrease the playback speed of YouTube video and mute will do the mute inside of YouTube but not system-wide mute. And then if I go to the next layer set here I have a set of, as I mentioned before, these Discord icons.  If I wanted to type in a Blinka, normally I would type colon Blinka colon and it brings up Blinka or, and you might not see this but I would click on, there you go, I would click on a little emoji list and go to the Adafruit set and click on one of the emojis there, which is great but this is really a lot faster with this Gizmo here, with our touch deck. So if I just click on my Adabot, it typed in an Adabot. I don't have it pressing enter for me because sometimes you might wanna include that in a continuous inline. You might not want it to always hit return but you could have it do that. You could add the keystroke for the enter key and that would give you the ability to just fire off emojis instantly. So I'll do one last one before I stop bombarding you with emojis but you can see it at play there, works really well and if you are crazy about emojis you could set this up with many, many more layers of emojis. I believe also the, I'll be working with Fome Guy on a guide for this and hopefully get him to do some good explanations of some of the tricks he came up with for making this work efficiently. But one of the things that we have, I believe is the ability to resize. So we may be able to do without too much difficulty on different size screens or even make more smaller buttons. So if you wanted to have more of them on there as long as your fingers can still touch them. Also this is a resistive touch screen. So if I, what's a, let me grab, I've got my little pencil here. It's got a little metal blunt tip on there. So if you wanted to use this sort of stylus-like, it would work like this. Oh, so Siege Grover says there's an 11 second latency on YouTube today and I just have to ask, is that a latency between when I'm broadcasting and you're seeing it on Twitch versus YouTube or is that audio desync? Cause I really hope it's not that poorly audio desync. Yeah, Fome Guy, he has a cool avatar but I don't know if we have an emoji for his avatar. Maybe we should make that an honor. So, oh good, audio's fine, says Andy. Thank you. When you say latency, I start to be concerned. So one thing I wanted to do is follow up a little bit. Last week I started showing some of the build process for this and I was saying I was kind of building it just straight ahead in Rhino, sort of drafting curves and extruding them and filleting edges and just kind of working off of some dimensions. I decided to rebuild it all using Rhino Plus Grasshopper which I mentioned before is sort of the proceduralism or parametric flow graph of your build that's available in Rhino and this approximates a workflow more like what you'd see in something like Fusion 360 or SolidWorks or something where you're creating a flow of data and you can always go back and update some dimensions in order to update your project without having to manually do it. So I'll just show you some brief steps of it. What I started with were some curves and these were the curves that I took dimensions of my board, for example, those are the dimensions of the TFT right there. I drew those out myself. I'm not gonna turn on dimension lines there but you'll see that they have some very specific dimensions and then I started doing things like offsetting it. So you can see this is an offset version that's because I'm gonna use it to carve a slightly thicker version of this out of my solid objects. So this is a extrusion of that. Let me, I'm just gonna step through some of these things so then I cap that extrusion. So that's kind of prepared now as a thing that can carve out from other stuff. This other curve that I showed you is the sort of main outer frame and I've got a, essentially I've built this as the frame and the base sort of as two pieces that then we assemble together. There's a outer section which I can then carve that intersection out of and then as we go along I'm kind of adjusting some of the, whoops, what have I done? Adjusting some of those dimensions to fit if I can show you in here. You can see now I'm carving out that, using that little boolean difference to kind of carve out that shape there, rounding out some edges and entering some little screw holes into there. So that's all of the process for the frame. So this is kind of the final frame top that I have and you can see the same sort of thing happening down here below with the main base. So that one's a little more complex. So what I do is I again start with some dimensioned curves and some vectors to extrude things on the angles. I wanted this 30 degree angle for the sort of tilt of the base there. So you'll see I'll go and take some lines and rotate them there and then extrude those up. Put a little cap on it so it's a solid. Carve out some little holes out of the bottom for my screws and standoffs to go. And the cool thing is this is a combination of geometry that I made with particular dimensions inside of Rhino that I'm then using to carve out as well as things that are just sort of entered in these nodes. If I go and change something like the diameter of those circles that are cutting out those sections then it'll update automatically in the model, which is great. So this is much more the kind of workflow that I was talking about last week saying, I'm ashamed I'm not doing it this way. So I decided I got to remember some, I haven't used Grasshopper in a while. So I had to go back and remember some Grasshopper and then go about building this again. So that's kind of like the final base shape there. And what I'll do, let me give you a shaded render of just that base there. One second, turn off preview there. Go to a rendered view. Hope I don't crash something. There we go. And oh yeah, I've left the top on there, but that's okay. So that's what the final looks like. And then I basically bake that. So all of this is procedural up until here where there's this relationship between all the objects as well as values that I've entered into these little nodes or formulas, vectors that I've picked. At this point, I have the sort of final model being created through this history of nodes. And then I can go and bake it, which when I do that, I think I've already got a baked one here. Let me do this cooking style, cooking program style and find, I'm sorry, I've got to make my windows bigger because I can't really work with the interface this small to print. Okay, yeah, so those are the baked NERB surfaces, solids and NERB surfaces. And then I meshed them before turning them into STL files just so I could kind of control the details of the meshing. So that's what, yeah. So that's the model file right there. That probably looks familiar to you. It's a triangulated mesh, which is what most of your three printer software wants for slicing and then I've sliced those and printed out these guys. So thanks for putting up with that. I just wanted to come back full circle. And since I had talked last week about, hey, I'm not doing quite the way I want to do it. I wanted to follow up and show you the proper way. So there's still, I think maybe just a couple of little adjustments I'm going to make, but otherwise I think this is ready. I may try to, I realized that my dimensions didn't account for the fact that there's a somewhat sizable gap on the edge of this TFT sort of physical screen, the glass if you will, and where pixels can go. These are all the way up to the edge. So if you center the board, you're never quite centering the display. So I may readjust things just to stuff over a little bit. We'll see it, the problem with that is that it'll take the screws and offset them from the screen frame, so maybe I'll leave it alone. But look for a learn guide on this. I'm going to be starting work on that soon. And again, like I said, hopefully FOMI guy, oh, we've just gotten a, we've got a FOMI guy icon in the chat. Thanks Hugo for grabbing that as a cool avatar. I don't know what that is. Is that, someone tell me, that must be like a character from something that I just don't know. I'm not up on. But yes, so that'll be coming soon. I'll probably put out the STL and step files for that, which might be useful for someone who wants to re-imagine it. I don't think the Rhino files are as useful to people because it's expensive software and it isn't what the maker community tends to use, but I'm happy to share it, that and the Grasshopper node network. All right, so that takes us kind of through. Let me know if there are any other questions about this touch deck. That's the main feature set as we've got it. I will show you now actually the code I had mentioned. This is actually, yeah, this is it. So this is the layers file, if you look here. This is not the main code. This is this abstracted, trying to think what the word I'm looking for is, but essentially the controls definitions is a separate file from the main code and I'm drawing a blank on the word, so I'm sure someone will help me out in the chat. The file here is just what's gonna happen when buttons get pressed. So in the main code it says, hey, I know the second button got pressed. This here tells us, okay, if we're in layer one, this first layers file is this section here to here, here are the buttons, zero through 11. So the second button getting pressed physically on the screen, if I'm in the YouTube mode, is gonna be the pause key. So all you have to do to change the functionality of these keys, again, sorry for the glare, there we go, prop that up a little bit, stay, is you can give it a label name, so you can see there, it just says pause underneath it. You can change which icon it points to. So right now I have a set of icons I made and they are all prefixed with PR for purple-ish, although I kind of went bluer as I developed it, and then pause, that's the pause icon. So if I just wanna change that, let's say I just feel like confusing myself and putting the play icon in there, I'll change that right now and in a second I'll save and when it restarts it should bring that up as the new icon and then the actions and we tell it, what are you gonna do? Oh, it's gonna be the HID key and then key code K. So you can do consumer control and the various consumer controls or you can do layout and it'll type in a bunch of stuff. By the way, in YouTube, play and pause are identical. They do the same thing and they have the same shortcut, so maybe I should pop something else in there. I don't even know if there's a stop, like play, pause and stop, they kind of tend to be all the same screen that just, same key that just is an automatic toggle. So right now, let's see, if I save this, you'll see it's gonna auto reload the code and again, this being a cool circuit Python display, we get to see the REPL show up there until it takes itself out with the screen blank and now it's loading up in there. You can see I've replaced my pause key with a play key, so I'm gonna set that back and I'll hit save on that so I don't confuse myself later. I think, follow me guys in the chat too. So if anyone has questions, if anyone's over, particularly in YouTube, if you have questions you're not over in the Discord chat, FOMI guy is there. Let's see, the one question, okay, Todd says, can we use Unicode combining characters to combine Adabot emoji and iBall emoji to make a FOMI guy emoji? That's a tough one, Todd. A question over in the YouTube chat, David Desa says, JP, did you find Rhino difficult to learn when you first used it? Boy, I'll tell you what, I started learning Rhino when it was in beta back in 1998 or 1999, so I've used it a long time and I think at the time I was already a alias studio and alias power animator user, so I was used to a NURBS workflow, originally it was just a NURBS package, it was kind of the first NURBS modeling program on Windows NT at the time, I believe, and so I think that the methodology of working with NURBS curves, NURBS surfaces and those kind of operations are maybe the bigger learning curve, but I think there are great tutorials out there, there's great video series, and I think it's, I've taught it a little bit before when I used to teach graphic software and I found people took to it very quickly. Someone said, can one call up websites? The question is, can you call up websites using this little gizmo? So one of the advantages that a device like the Stream Deck has is that it runs some background software on your computer that's always watching the device and so it has sort of system level application controls so it can listen for things to happen and then serve up the results of those. This is just a simple HID keyboard so you can do the kinds of things I've shown here. If you wanna go one level more sophisticated, you can install some macro software on your computer. An example I'd like to give you is Quicksilver on the Mac and if you look at a guide, I'll bring this up real quick. If you look at this guide I did, about one second. If we go to learn.adafruit.com, I called it the Launch Deck and it's a similar project to this but it uses the Neo Trellis M4 and I created an app launching application using Automator. I think, has Apple changed Automator? Again, I can't remember if that's what it's called now but that does system level stuff on the Mac. You can use the Windows 10 task bar to do things like launching a webpage, launching an application and then Quicksilver, do I show it here? Yeah, Quicksilver is and there are other pieces of software like this. It is pretty in depth, the kinds of things it can do. It can run actions that are complex such as launch a web browser, a particular web browser whichever one the system favors and go to a particular URL or launch my email program and start a blank email that's addressed to, you know, LeMore. So that's my answer to can you do more sophisticated stuff? Yes, but you're certainly not dealing with the same level of sophistication as far as I know as the Stream Deck or its competitors which have pretty well developed sort of server software sitting on your computer watching for events. All right. If there aren't any other questions on that. Oh, sorry, one last one. Car Xpava, Karen Randall asks, is Rhino at all like SketchUp? Yeah, there are definitely ways in which it's similar because the concept of creating solids, extruding them, creating other solids, using them to carve things out. That Boolean solid Boolean workflow is pretty much how SketchUp works. It's fairly constrained to that and Rhino certainly works that way as do a lot of other solids programs. But then it goes way, way, way beyond in the drafting ability and the inferencing and ability to snap things. Although SketchUp does great snapping kinds of stuff. I'm not here to bash software, but I've used SketchUp quite a bit many years ago and it does have a similar workflow to some of the kind of carving types of things that I'm doing here. All right, yeah. So actually one last thing on the touch deck before we move on to preview our upcoming project. Fome Guy is in the chat talking about the speed of the bitmaps. So I actually pushed us to go to larger bitmaps. We had smaller ones at first, I think 48 by 48 pixel. We've gone up to 80 by 80 pixel, which clearly these take up a little more space. This very morning I updated, actually this would be kind of a cool experiment. So if you watch, do I have a second USB-C port? No, I don't. Okay, so I'm just gonna unplug this in a second, but watch right now, let me switch to my down shooter and I'll show you if you look at how quickly or how slowly bitmaps load.  Those are all 16-bit RGB BMP files. And then this morning, I unplugged that one, I converted all of those to indexed, 256 color indexed, which makes, makes, makes, makes less than half the size. We'll see if we can get this one to load up here. My first take on it, I didn't do it side by side, was that it didn't really change the load speed that much. But let's, oh, this is, I may have an old, old version of a circuit Python in here. I had a, I had this issue before where I have to go into the REPL and kind of goose it before it wants to launch. So one second, let me tell it to relaunch from the console here. So those actually always load in faster that first time. I think it might, yeah, it's about the same speed. It does not look any faster to me. And those are, those are much, much smaller files, but they're, I mean, they're all kind of small anyway. So we'll see. I think Lady Aida had some suggestions for some possible solutions, maybe using Sprite Maps. So we may, we may be able to get that faster, but that's partly an intellectual exercise, because I don't imagine if you're using this kind of thing, you're using it to like page really quickly between lots and lots of stuff. You kind of are going to be working in Photoshop for a while and want to use it as a Photoshop launcher, and then you might switch over to YouTube to watch some stuff for a while, switch it to that. So I don't know that a blazing fast swap to layers will matter that much, but it'll be nice. So we'll see. Jay Furcian, if I'm getting your name right, says, I can't wait to see this guy. I made a much simpler version of this two years ago using a PyPortal and Automator. I've always wanted to revisit it. Oh, very cool. So there's a, there's a PyPortal app launcher. If you take a look at the Discord there, very cool. All right. So let's take a look now at the, at the new thing. So I'm going to switch over to a different camera over at my work bench there. And let me go and put myself into the corner there. So what's going on over here? What's all this you might ask? So as you'll remember last Tuesday, two days ago, I created the knob controller for, let me run this, for the Raspberry Pi 400 that uses our little Quad ADC and four knobs. So I built this little gizmo here. I've just, I'm holding it in something that'll give it some weight. Let me zoom in for a second. There we go. So this is our STEMA QT cable connecting it up to the cyber deck on the Raspberry Pi 400. So that just angles and brings out all the GPIO pins. And then I soldered up this board with, take it out of here for a second, with four potentiometers and lovingly bent wires and tried to make it look clean and neat on this Perf board. And these are just sending, at the end of the day, they're sending 256 levels of analog of varying values or rather the sending analog voltage acting like voltage dividers and that gets interpreted by the chip as 256 values. So what I showed, and you saw this on the little recap video before, is that I'm controlling this Pimaroni unicorn hat HD. And I just wrote some simple code to move some neopixels around up and down and left and right for these two lines and then sweep through the different hue values and also change the brightness on that. So I mentioned to Lamor, I said, hey, do you want me to write up a little guide on using analog inputs on the Raspberry Pi? Because as I've mentioned, there aren't any. The Raspberry Pis don't have analog inputs even though they have all this GPIO. So if you want to use knobs, you kind of have to add some sort of analog to the digital converter as ADC. Zoom back out here and she said, yes, that would be cool. In fact, what I think would be a really neat demo, try to get that in focus again, is to control a synthesizer on the Raspberry Pi. I said, hey, neat, I like synthesizers. Who doesn't, right? And so what I did was I took a look at Sonic Pi and Sonic Pi is a software synthesizer that's often installed on a Raspberry Pi distribution if you get one of the official Raspberry distributions. It's often right there or it lives up in the install some software wherever they've got in here somewhere. There's ad remove software and then they have like a list that's got some recommended software as well as you can kind of pull in anything in the world. So Sonic Pi is a very nice educational coding platform that is coded in Ruby and acts as the front end for a really powerful software synthesizer engine that's called Super Collider. And so Super Collider, you find it in a lot of devices, some really high end devices. You've seen me show, we've got our friend Steve and Noriko in the chat here. He has made a version of the Monome Norns before. Norns is a super high end synthesizer coding box. Steve's made one called Fates. And the Norns and Fates, they use Super Collider as typically as the engine, you can put other things on there, but usually they use Super Collider and then they have a little scripting language front end similar to this sort of idea, they use Lua. But this is, if I can zoom in here and you can see this little funky cyber screen I've made here, let me move it down a bit, try to avoid glares. This, not that, this, this is Super Collider. It looks like a coding ID. And in Super Collider, we typically do things really simply, you can say play 60 and it's gonna play a MIDI note that's MIDI note 60, which I always forget is that like middle A or middle C, something like that. But you can get much more sophisticated from there by saying, oh, I want a particular synth engine and I wanna control parameters such as not just which note is playing, but what the frequency of a filter cutoff is or what the amplitude, how loud it is, the sustain, how long the note sort of trails off after it's been played. And so, I thought, I'll bet that we can control some of the parameters inside of Sonic Pi using this little gizmo and some Python code that is sending messages from a Python script over to Sonic Pi. And the way this is often done in software is either with MIDI or with OSC, which stands for open sound control. OSC is like a latter day more advanced MIDI type of ideas for sending information from one application to another related to music things generally. And as it turns out, I'll show you this over on the computer later, as it turns out, it took about one library, three lines of code in Python and two lines of code over in Sonic Pi to send OSC controls derived from what I'm doing with my knob over a UDP to Sonic Pi. So enough talk, let me play something. So what's gonna happen here, and again, I'm sorry, I don't know if you can see that code. I've left my visualizer thing running, so that'll still do its cool stuff, which is just, hey, that's just fun. And then I've got the same knobs that are controlling these four visualizer parameters send four different sets of values over this OSC into Sonic Pi, and those are for the note. So I have something in here that says A, B, C, and D are synced to the thing that's sending OSC. And what do I interpret those variables as? A will be the note, B will be the cutoff, C will be the sustain along the note trails off for, and D will be the amplitude or how loud it is. So what I'll do now is I'm gonna hit play and I have a little sort of arpeggio that'll play, and you'll hear changes as I turn the knobs. Here we go. So there's that frequency-filtered sweep. I'll change the notes, the sort of root note, and now I'll change the sustain of just the first note. So that first note will start to mush and stay present. See how it's just hanging out there. Now if I set that amplitude real low, we won't hear it anymore, it's still playing. And one reason I wanna do that is I'll show you, hopefully you can see this, if I expand this window, this little colored set of text flying in here, these are called the cues. Those are the external events that are coming in from that Python code. If I switch back over to Python, this code here, let me see if I can make that pretty big and hopefully you'll be able to see it. Let me zoom in on that text. I'll stop that code from running. I can turn on the plotter, that might be useful, and I'll run that code again. It gave one spurious send. So as I change things like the filter, you'll see that blue line moving up and down. So every time this code goes through a loop, let me turn off that plotter, what it does is it's checking, I've installed this Python OSC and I'm importing the OSC message builder, as well as this UDP client. And then I set up this thing called a sender, and it has the UDP client as a simple UDP client to the machine itself, <IP_ADDRESS>, port 4560, that's the port that Sonic Pi is gonna listen for. And then I send a message. That's actually why that first we heard it one time because I actually send a message at the beginning here before I've checked the dials. And that message has a little format. It says it has a path trigger slash profit, profit synth is one of the synths that it emulates. And then these four values. So that's the note value, 143, the filter cutoff 110, the sustain is set to one and the amplitude is set to 0.7. So then what I've done is the rest of the code is the same as I did on Tuesday. I'm using that PCF 8591 to read these four knobs. And then I'm changing that raw, actually the raw value we get is a 16 bit value. So we get zero to 65,535. I take that and I switch it into kind of two different sets of ranges. One is the set of ranges that changes, let me run it again, that changes this display. Turn this volume down. So I need to set it to zero to 16 or zero to 15 to change those 15 rows and columns. And then depending on the range of what I wanna do over in the synthesizer, I send things like MIDI notes. So if we look at that MIDI note range, let me hit stop here. And I'll go back over some of this stuff on the main monitor where you can see it a little more clearly, I think. Oh, that's pretty big, hopefully you can see that. So here are some, make that even a little bigger so I can get there. Here are some of the remappings of those values. So the OSC note value, I take my raw value that comes in. I map it from zero to 255. I use that in both instances. But then to turn that into a note, I say, okay, we'll make this an integer and we'll use the circuit Python map range library even though I'm in Python here, I'm using a lot of circuit Python libraries. They work on the Raspberry Pi. And thanks to Dan Halbert for letting me know that I could do it that way. It makes life easier for me. And then this is the map range is taking whatever comes over that OSC zero value, expects to bring in a zero to 255 range, remaps it to MIDI note 43 to MIDI note 58. So I've got two octaves if I've done my math right there. And so on I do that for the different things that I'm reading over in Sonic Pi. And the result is what we've seen. So then back here in Sonic Pi, let me see if I can make this full screen and hide some stuff. I'll hide those cues, show log, show queue log. That'll help, right? And I can make this bigger and scale that code up a bit. A bit, a bit, a bit, a bit. I'll do it, okay. So that's the full code in Sonic Pi. Let me just move this down a little again. And is that in focus? Sorry, I have a hard time seeing if that's better. So, and I apologize if people are in the chat telling me to focus. So here, all the Sonic Pi code is doing is it's creating a live loop. It is using these four variables to cast to whatever comes in over OSC. So there's four things coming over from OSC. We sync up with those. And then I tell the synth name, profit. We could change that. We can even, even midstream. So actually if I play this, let's go back and run our sender. So while this is running, it's kind of live coding environment. We can go in and say, I'm gonna do Hoover. And I'll just hit rerun. Had some buffered in there. That's a different synth. I think we can do maybe a sign. No, that's not a synth. So I just gave it a bad name. And it's like, no, you don't. I think Super Saw might be one. Now we get this cool buzzing. Okay, I'll stop that. I'll hit stop on this. So this is one of the neat things about this is this is live coding concept where it's constantly running. You can change things and just tell it to kind of refresh. It doesn't even miss a beat. It keeps the tempo and it adds in your changes. Here I'm just throwing in a little sleep and then I'm adding two to the note each time I run through and that's what gives us that little sort of boop boop boop boop arpeggio that runs up. So this right here where we have the synth, I said, okay, I can just manually change that. We could change that also from our knobs if we wanted to give it some little sort of selection ranges. And then right there, note is A. So that's whatever came from the first knob. Cutoff is B, came from the second knob. Sustain is C, came from the third knob and amplitude is D. All that running on this little gizmo right here. Let me zoom out a bit. I'm really excited about this Raspberry Pi 400. It's super cool. I built a funky little frame for my monitor there. That's it, that's the gizmo. I'm running out over HDMI to this display. I'm running out over a little USB audio dongle, little sound card in a box kind of thing, which makes life a lot easier. It gives me a line out. There is no line out on the Raspberry Pi. I also have had problems getting the audio over the HDMI and then getting the HDMI resolutions I want. So I skipped all that. This was Lady A to suggestion. She said, why don't you try one of these little audio cards? Worked great. And then our love little analog ADC, giving the knobs the treatment. So let me run back over to my desktop here and see if we've got any questions. And I can also, so let's say, WagonLoads in YouTube asks, YouTube chat, is iSquaredC fast enough for MIDI interface? Yes. Someone in the chat might be able to remind me of the speeds of those two things, but I believe iSquaredC is quite a lot faster than the, whatever, 3200 bot or wherever MIDI is. MIDI is pretty slow. Yeah, ASUS built a code, JP making the opening song for Stranger Things. It's hard to not make something really reminiscent of that arpeggio from Stranger Things. Let's see, what else? Other questions? Could you use a touch mouse pad for the X and Y? Probably, yeah, like if you use, in fact, I have one of these here somewhere. There's a, we have some little digitizer touch screens. Here's one, I think it has a little controller and I'm not sure what it outputs if it's iSquaredC or not, but these types of little, this is from a Nintendo replacement part, but it's a little digitizer screen and it comes with a little controller board, things like that I think you can get to just send out. Maybe that's digital, so maybe it's not a good example, but yeah, X, Y pads that are analog, you should be able to read joysticks, you should be able to read because that's just two potentiometers. MIDI is 31 to 50 BOD, super slow. What is iSquaredC? Like a thousand megahertz or something like that? I just made up numbers, it's fast, fast enough for this. I think it's like between 400 megahertz and a thousand megahertz, something like that is the range on iSquaredC that we can use. Someone tell me if I just made all that up. Oh mate, there may be questions. I was scrolled funny here, let's see. Yeah, I can't take it apart to show it or I don't want to right now, but the Cyber Deck, man is it cool. In fact, do you know what I'm gonna do? I'm just gonna pull the plug on this, sorry. Sorry Raspberry Pi, so it should have shut you down, but I'm doing a show here. I'm just gonna grab this. So here is the, here's the Raspberry Pi with that Cyber Deck. Phil B did the super cool silkscreen on it, ginemonic style, and then I have that hat plugged into it, but these come, boop, right out of there. That's what we would be interfacing with normally, which means a hat like this, I think would be facing backwards. So you want something like this to use different hats. We just have a bonnet version that's like a half height size, and this has the JST3 pin connector for stuff like NeoPixel strips, analog stuff, and the I squared C connector there. Or I guess you'd have to use digital things with that. The one thing I will tell you is it's actually possible to be off by one with some things. This one is keyed. That connector has that little keying notch there, so it pretty much goes in correctly, but I managed to put a non-keyed hat in there, one pin off and wondered why it wasn't working. That is why it wasn't working, so be careful, you can actually get the pins off by one. There's enough space in there to do that, which is too bad. Yeah, so cool device, hopefully I didn't make it too angry by pulling the plug on it there without a proper shutdown, but these things happen. Yeah, nunchuck, someone mentioned, you could use the little nunchuck breakout, and that's a, there's a little STEMI QT board for that. I've got one right here somewhere. Will I find it easily? Probably not, too much stuff. All right, and then I did mention, I would look a little bit at the code here, so this, let me open up. Are you in here? There, almost, standby. There it is. So that's the code that I was just showing or similar. I think I made a couple of changes for doing the Sonic Pi synth sounds, and this is what the code that's doing both the unicorn hat and the OSC messages here looks like. So I'm bringing in the message builder and the UDP client. These are the pertinent lines of code here to set up the Python code as the client, which the Sonic Pi is set up as the server to receive that with, what, just this line right here? Sync, that's literally all I have to do is say sync. It's pretty great, and I'll show you, I flashed this up before, if I pop over to this tab here. Oh gosh, that's a big, let me make that a small knee. I think I Googled OSC in Sonic Pi, I came up with this one, here's how you receive it. Boom, and it showed a basic listener mentioned doing it in, I think, closure and Python. That's the code there that I grabbed and was able to install it with PIP3. So very straightforward, and I'll be doing a guide on that. So may also try something funky with that. We'll see if I can do a mirrored display with one of these little Pi TFTs, instead of that visualizer, then we'll be able to do things like see the scopes, maybe even, it's a touch screen, maybe even press play. The play button there, the interface might be too small, but there are waveform scopes for, I think, the spectrum, Sonic spectrum frequency as well as like moving waveforms over time and a leisure zoo pattern and some other stuff, so. Might be cool, we'll see. All right, anything else? Let's see, that's that code, that's that code. We've looked at all the code. I think that's gonna do it. So thank you all for tuning in. Thanks for being active in both the chats. I'm sorry, if I missed some of the chat there, it's a lot going on, but thanks for coming by both YouTube and Discord people. And I think that's gonna do it for today. I hope you had a good one, I did. Now I'm gonna go off and build some more of this fun stuff and write it up. So thank you for Adafruit Industries. I'm John Park. This has been John Park's Workshop. Bye everyone.


Hey traders, this is Tosh. I go by T Bradley 90 in the my investing club chat today One of our moderators Matt who goes by Chicago trader in MIC has a how-to series every Sunday on Fundamentals or reading filings and today we have a special video on securities purchase agreements and also a look into Derm DERM and While today is just a preview of the full length video if you want to watch the full length or any of our Exclusive content than become an MIC member Hey guys, what's going on Chicago trader here checking out with the weekly fundamental video? I Apologize I was out of town last week. So I wasn't able to do a video This one is gonna be I had quite a few DMs on the Derm when it moved I'm just kind of my thoughts around it. So I'll share with that with Durham. Obviously if you guys remember it's a big 600 million dollar company gaps up, you know near a hundred percent they do an offering The thing went up pretty much for the next day or two so I kind of you know, this doesn't happen a lot or kind of an anomaly if you will but AXO sim was one of them that happened recently and told it pretty well So the first thing there's a lot of confusion that from some of the people that were DMing me On the 18th, you know, they were asking about Pricing in total and you know who is doing it and you'll notice a lot of times There's a two-day difference. So they come back in within 48 hours and they fill out The details of the offering so priced extremely well 9.8 million shares so raise to $122 million and here's where you kind of got to watch out anyway So you got city. I mean Guggenheim is a pretty good firm counting canter and so many smaller places obviously Don't have quite the reputation, but it's oversubscribed. I mean look, there's six people trying to get in on it You know, this wasn't one to just pilot and short and I've kind of actually mentioned that to him a lot of times What happens to is when you have this much Demand for a deal Say you work at city group and you know your client wants 10,000 shares of the deal You may only get allocated for 5,000 if that if you're lucky, especially smaller guys They they probably don't get very much of the deal at all So what'll happen is if they really like the deal, you know, this price at 1325 and You know if it dips to $13 they'll call their clients by in the open market if they really like the deal You know you go back I think can't remember if they had a ATM outstanding or not, but if you scroll Come check out their Netline. Yeah, so for the year. I mean look they lost 220 million dollars. So they're definitely burn it through some cash real quick but And you can kind of see like I said, it's still holding up pretty well in the daily experience afforded right there that 1275 13 area, but nothing for me to fight anyways Maybe somebody smarter than me can Give some more color on it With the securities purchase agreements there's a couple stocks that have moved recently that had them AKTX Bo XL So I think the most important thing is it's just an agreement between a purchaser In the company the company can sell, you know, usually it's over like a three or four year period They can demand that they buy, you know certain amount shares or a certain amount each day There's a little bit of varying stipulations on how they can buy it with price Hey traders, this is Tosh. I go by T Bradley 90 in the my investing club chat Just wanted to reach out and say if you have any questions about M. I see joining M. I see maybe you're a member already You have three ways to contact myself personally and through M.
