LIVE Shop Talk 11: Review of the New Raspberry Pi 4

[Applause] hello guys this is polemic order from top tech boy comm and we're here today with our lives shoptalk number 11 where we're going to be reviewing the Raspberry Pi for what I'm going to need you guys to do is pour yourself a nice big mug of iced coffee do I have audio I certainly hope that I have audio this time and I really apologize for the little glitch in the earlier livestream everything was set up right everything was configured right the microphone was on but for some reason my broadcast software just dropped the channel and even though it was connected it wasn't coming through and it required a system reboot I think really what I need to do is I need to reboot the system every time before going live because this this live broadcast business with all of these different channels and stuff really put a load on the computer probably a smart thing to just reboot every time right when I'm right when I'm starting and the the problem is is that I've got just a crazy insanely fast computer system like I have a really state-of-the-art computer system but the problem is it's the pipes coming in and out and very quickly it's like you overwhelm the USB channels and it kind of doesn't matter how good your processor is if you don't have really good pipes coming in and out you can get overwhelmed okay are you serious okay so Dirk welcome thanks for coming back Dirk no audio or visual video are you serious please tell me that it's working okay yay hello hola hello job okay's people are saying it's working sound good whoo yes audio and video sounds good loud and clear hi Ted hi star fix hot sticker shock okay many at the controls boom yes we have sound this time okay yeah it hey you guys that are helping me out over on patreon really appreciate it cuz that's allowed me to get this nice microphone I hope you guys have seen putting aside the little glitch in audio Paula go I hope you guys are enjoying much better quality audio with this microphone also because of the help from patreon I'm getting some other gear in like I've got a little over a little graphics tablet coming in because what always bothered me is as I'm trying to do math with the overhead camera you just see my big ol ugly hand and you my hand as I'm riding just cover up covering up what I'm riding and so with that graphics tablet you should be able to see me and then you should be able to see the math I'm doing in the background so that's what I just got other gear that I'd really like to have is you know how I use this webcam for my desktop shops and it's really a pretty nice webcam but it gets confused on focus and then that just throws me off when the focus goes wrong so next thing I'd like to do is get a little bit better equipment on the camera also I really need to get a computer system that like what I did here I got a really fast computer but I wasn't really thinking about the bandwidth issues and so I need to get a computer that's a little more oriented towards live streaming blood oh no for that nonsense where I talk about my patreon account and let's get to business did you guys get your iced coffee let's take a look at the let's take a look at the comments Oh log okay from Moscow oh man welcome you guys need to quit trying to hack our elections but of course we all know that's nonsense right welcome to Russia welcome from Russia all right all right very good good morning off from Alta Loma California Joe welcome Jeff welcome cap electronics good Muhammad hey we got a good little group come in here your microphone is too big how much the microphone is a Yeti microphone and I swear I went through like a couple dozen microphones trying to get good audio and what really bothered me in my earlier videos I was getting really nice video but the audio sounded like a 10 and it was popping and cracking and that really bothered me so I broke down and bought this Yeti and I don't know what you guys think but I've been really really pleased with the I've been really really pleased with the quality okay I have audio okay sounds good Mohammed thank you and welcome Joe I have just have a busy circle rotating Joe try reloading because I think other people are getting this thing coming in so Joe I think it's working I got it now okay Joe good cracked me up oh okay I don't know which part cracked you up but anyway we can have a little fun here right like I really like everyone in the world I mean I really like everyone in the world everybody's my friend and I don't want to fight with anybody I don't want you know I just want us all to get along and that's what I like about this channel is we all get along what I really like is the comments are nice and and I'm nice to you all and you all are nice to each other and so I think we have a nice little community here of people from around the world being nice to each other and that is kind of nice Oleg says he's enjoying the the tutorials thanks for the content okay I love my Yeti okay Jim glad to hear that Texas snack 'old hello for Aledo Texas snack good snake snake eat whatever you are where are you in Texas okay hello from the UK with a cup of tea oh no Meah you guys I've been to London I've had tea I love the tea over there but you guys need to at least expand your repertoire to a little a little iced coffee okay thanks for making this from India hey from India from Maldives man we have got a Mohammed from all died so we've got a worldwide audience okay well we are here today to talk about I'm just sitting here talking about a bunch of nonsense we are here to talk about the raspberry pi 4 and yes this is a live shot you can see the Raspberry Pi 4 is about the size of a tea bag okay about the size of a tea bag and yes I already put it together I didn't wait for you most of these reviews are the unbox singen you know the guy has the overhead camera and his neat little knife and his fire extinguisher and he takes it and opens it and takes it a hollow box and shows it to you the unboxing I'm not that guy man hurts and then I run home and I beeping even the ones with the fan this has the fan on it because the Raspberry Pi 4 is really pretty pretty heat generating type of things you really need a fan if you're gonna use this and then I got the thing put together and I did in fact get it booted and so here you can see my nice Raspberry Pi desktop and you know kind of a wit looks a little bit like a you know it's a Linux but it looks a little bit like a Windows type of GUI interface that you would be that you would be comfortable with okay hey we got FM over from Iraq hey welcome from Iraq man I've never been there but I hope one day conditions would allow me to visit Iraq Singapore Mike Wong honky I have been to Singapore man and that is like the most beautiful city in the world it is like a gleaming city on a hill Singapore it's an island it's a nation it's a city all in one beautiful beautiful place I ate at the raffles hotel and I believe that it was their hundredth anniversary and it perhaps was the finest dining experience of my life so welcome from do you guys from Singapore from Alabama ok man Alabama also roll tide yet also Sweet Home Alabama perhaps one of the greatest songs ever written hi from South Africa yeah cap electronics have from South how does it hi to you know wait London Fog York shorty I think I've been to Yorkshire I think in my travels in London I've been to Yorkshire a Yorkshire T Beck I don't know I was in Yorkshire I drank tea I don't know if it was Yorkshire tea but I drank tea in Yorkshire I met the new improved Arduino tutorials hey great now looking forward to the pie review just recently got the 3 don't yet know what to do with it Oleg boom Oleg just said I got the pie 3 and I don't know what to do with it well Oleg I got the pi/4 and I don't know what to do with it it just my pie is a lot faster than your pie so I'm sitting here spinning my wheels even faster than your spending your wheels so you guys let me kind of know what your take is on the pie is the pie a platform that you're interested in or is the pie a platform that you're not interested in I want to kind of get feedback from you guys because there's these kind of like parallel threads we have going on we've got the Arduino going on you know I've got that introduced in traductor e tutorial series on Arduino it's moving ahead a lot of momentum over there people are enjoying it then I've got the advanced Arduino project which is the non axis IMU getting some interests there and then most recently we are working on the most amazing the most incredible the thing that I am probably the most excited about of the Jetson nano okay and those things we have going and we have momentum behind but then we have the Raspberry Pi and the real question is what to do with the Raspberry Pi so you guys let me know what your feeling is on the Raspberry Pi platform okay because like normally when people do a review of the Raspberry Pi 4 they start giving you thrown out all these jargon and it's got this processor and this many CPUs and this many GPUs and gigaflops and this and that and it's starting running all these benchmarks about how fast it is in blah blah blah that's all a bunch of techno babble my question is I'm a big-picture guy the question is what can it do what can it do for me how does it fit into my projects and that is kind of where I'm coming up with a big question mark because there's some incredible things that I can do with the Arduino all right and then what I see the Jetson Nano brings it brings a full-fledged supercomputer which is connected to GPIO pin so I can have in my little world of projects super computing capability connected with GPIO pins that means interacting with the outside world and my mind just goes crazy you guys are going to be shocked with some of the stuff that I've ordered that I've got in mind for the Jets and nanos I hope you guys will stay stay tuned on that but you know the thing is is that like if you look at my desk I'd bet I would bet not exagerating either I've got 75 raspberry pies in my room okay I've got raspberry pies coming out the wazoo okay and the thing is I just don't know what to do with them all right if I try to use them for educational tools it's like they're so hard to use because it's like alright I'm gonna need an HDMI cable and the HDMI cable has to match the plug on this end and then it's got to match the monitor I have and so it seems like if I try to use one of these either I don't have the right cable or the cable doesn't match the monitor I have I just end up running around in circles trying to get that then I've got to get a keyboard coming out I got to get a mouse coming out I got to get Ethernet or I got to try to do Wi-Fi in which case I got to kind of get it configured and then I've just got by the time you get this thing hooked up you've got this kind of octopus of things coming out and for educational purposes it's just too much to keep track of and so I've got all these PI's but anytime a student wants to use one they start getting kind of frustrated getting things together for a complete system the other thing that I don't like so much about them is that it's really easy to corrupt that SD card like if you lose power in an unfortunate way without shutting it down you can corrupt it or if for some reason it jiggles and comes loose a little bit you can lose your card so it seems like a lot of trying to get the you know trying to keep a good card in it and then if you're trying to use it for like a server or something like that those little cards are great for cameras but if you're using it where they're constantly being read and written they don't last forever okay they don't last forever and so those are kind of some of the problems that I that I've had okay let's look at some of the comments here okay we've got oK we've got hello heretic Kano's I'm sorry I can't say your name right chop from Holland hey man I've been to Holland like four times lovely love the bicycles great chocolates you guys have over there Nick no water your video me and Nick it should be working I think it should be working for most of you okay great you want to pass all like what are we gonna do with the pie that's the problem that we have Joe have you tried o le d dis plays I have not I have little dis place I have a little LCD displays but I haven't again I haven't figured out what to do with the pie so I really don't know why to put the display on can you make a tutorial on controlling the Arduino through the use of an application on the PC we've got those look I think look at my Raspberry Pi Python lessons I mean my my Arduino Python lessons and also the 9 axis is going to be a fresh look at interacting between the PC and Arduino so you might check those out I used my PI 3 as an Amazon echo okay that's great Martin power to you I just don't want Amazon listening in on my conversations at home call me old-fashioned what I'm sitting talking to my wife I would rather that conversation be private so I tend to turn off electronic devices call me crazy okay suggest me any recent research projects using pi yes okay like I saying I'm trying to figure out what to do with the PI okay Mike Wang Hong Kong is using PI for is my second dekstop okay I could I could kind of see that all right I could kind of see that hello Paul and chat I hope you all are having a good day well welcome Chris Joe Martin you own personal echo or actually connected okay working now using Safari Chrome didn't work okay also one use for my secure web and Internet services okay so my question there is is that do you have problems with those SD cards letting you down like it though at the worst possible the worst possible moment that would kind of be a question let me get through these questions and then we'll talk more use mine for Christmas lights okay Christmas lights but you see that's kind of the thing it's like could you do the Christmas lights I mean would you be able to do them with an Arduino I'm all right well I guess you could have a little bit more of a graphical interface where you could have like a cool display so okay I can see that I can see the Christmas lights I think that Jetson Nano let's see in Arduino are already covering enough maybe stick to that and go as deep as possible I kind of it I kind of agree with that because let me tell you like what I would if I was going to be using a pie and when I do use a pie I can't figure out why you know I really can't figure out what this pie for is doing for me where I do kind of use the pie is the pie is the pi zero which is this little bitty this little bitty baby pie and you can get one for five bucks or the Wi-Fi version you can get with ten bucks and it has this it has Wi-Fi for ten bucks and then it has this camera connector so you can get the little pack and put it on here and in something about the size of a pack of chewing gum you can be doing live streaming which is really pretty exciting and so I use this sometimes because you can have a very small video camera or you can add video to a project so I have used the PI 0 now the Jetson Nano does exciting stuff I can see the PI 0 but if I needed a little more horsepower than what the than what the Arduino would do I would probably go to one of these ESP 32 boards and they actually have an operating system where you can run kind of a Python light like a little kind of simple version of Python and this I like it because it doesn't have an SD card it's like the Arduino you turn it on and boom it's on you don't have to worry about things getting corrupted and it has more horsepower so kind of in my view I love the Arduino I love the Jetson Nano if I need something in between I am probably going to go to the I am probably going to go to the ESP 32 now I didn't even put like I think I prayed for this system I think I paid probably it was probably like 150 bucks by the time I got the bells and whistles in the case and the chords and the power supplies and all that one of the things I didn't like is you can't use all of your old Raspberry Pi power cords this has that other type connector on it and therefore you can't use your old power supplies and so now you're going to have one set of power supplies for one set of raspberry PI's and you're going to have a different set of power supplies for the new raspberry pi 4 so I spent probably a hundred and fifty bucks or so on this by the time I got all the bells and whistles and okay it's nice to look at it's nice to play with but if I come back over here you know like the the guys that are the smart guys and know what they're doing what they do is they go and they do all the benchmarks and they tell you all the numbers and they give you all the technobabble but as far as me as a user and a maker I'm not perceiving anything I am not perceiving any like really radical new capability that this thing has over a Raspberry Pi 3 so like if I open up this spreadsheet this lib rias spreadsheet okay it opens up kind of like on the PI 3 so for the things I'm doing I am not really perceiving any real difference okay these were the two things that excited me about the Raspberry Pi for like I thought okay I'm gonna get one and then I might be able to do something with it and the first thing was remember our non-access project I thought will put the you know like as we move forward maybe put the bno 0:55 on the Raspberry Pi 4 and then have it do the visualization there on the floor instead of python on the desktop PC so sort of an all-in-one unit where you were doing the visualization ok I did get the Python the visual Python installed on the PI 4 but instead of getting like sixty to a hundred frames a second like I do on the PC I was getting one frame a second and it was running but it was so kludgy as to make it totally utterly useless so I marked that off I can't use it the because it does not run the Python for sufficiently to do the visualizations on the B&O 0:55 the other thing my friend that I got excited about like you notice I do this broadcast this live streaming I got yeah because thanks thanks again to my patreon helpers I've been able to get an AI system and I've got some really nice broadcast software I got studio lights got a nice microphone got a nice camera I've got a nice studio but I thought hey wouldn't it be neat if I could show people how to make a studio using the Raspberry Pi for a webcam and then instead of a green screen just get green paper or paint at wall green and could you for a really low price get a really pretty impressive video studio like what I have but just kind of like you know really low cost and that's what I was planning on doing and there's on Linux there's this broadcast software called OS B which is like open source broadcast in it really for free does some pretty amazing things okay but guess what OS B will not run on the Raspberry Pi 4 because the Raspberry Pi 4 does not support OpenGL which is kind of like a protocol that is required by OSB so denied twice in a row so I've got a hundred and fifty dollar spreadsheet here and okay so you're right you're using it as a desktop okay but man if I really wanted kind of like an on-the-go low-cost type of desktop I'd go with a Chromebook okay how to really go with a Chromebook where it's like opens closed put it in the drawer put it in you know it's like more together in neat then then something like a Raspberry Pi with all of the the cables coming out of it and I know the idea I think one of the ideas behind the Raspberry Pi was make a computer for $35 so that you could have computers in the third world and it's a great concept and man I would love the third world to have more computers but before you say that you really need to go to the third world and you need to see the problems there and I really don't see the Raspberry Pi at all to call in bringing low-cost computing to the third world because first of all you're gonna need a screen in the screen and the cable and then you're gonna need power you and the power supply you're going to need blah blah blah and by the time you do that you get to the price of a Chromebook in a Chromebook like if I were gonna bring computing to the third world I would get a solar panel and in a Chromebook okay and then I would work through NGOs or I would work through Christian organizations so that you could honestly distribute those things without all the corruption coming in but I think Chromebooks are the way that you can more practically get computation to the third world I just don't see the Arduino you know it's not protected enough you know is it roofs leak over there it rains dust is everywhere crime you know I don't mean I'm not saying that in a pejorative sense but I just mean there's a lot of there's a lot of mud and gunk everywhere so I'm just not seeing the raspberry pie being something for the third world okay let's look at some questions and then we'll get back over here let's look at some of your comments let's see man we've got some good questions here let me pop out this chat and let me go through these let me go through these chats did you guys get your iced coffee I hope you got your iced coffee let me make this fullscreen they don't make this chat very easy for me to see okay so Nick says that he's using Safari okay man I just looked at all the hidden files that chrome is putting on this thing and it makes me want to get rid of Chrome why all the hidden files okay for me home cinema in my datacenter another micro SD with retropie okay I can see that stone it does everything a normal echo will do but you don't need the actual echo okay that's interesting we got hello from Tariq sorry I can't pronounce these things also uses for my secure web and Internet services alright Stoneskin it sounds like you've figured out a little niche for your PI and I'm happy for you Martin can you ask to hear moot music from Pandora use mine for Christmas sliding in and home automation okay that's good mark I think the Jetson Nano oh yeah I like the Nano and do you think that learning the Jetson Nano is a big step instead of buying the pie for man I really don't see the pie for as being a machine for artificial intelligence I'm going whole hog into the Jetson Nano man that is going to be the platform that I am going to use because it's got those 128 cores and it gives you an image that will give you software that will know how to use those cores and that's kind of what I am excited about okay chrome didn't like the broadcast on my Mac okay good idea about listening in I wonder about that too yeah you know it's just like I swear I was having a conversation with my son-in-law about sunglasses just because I mean it was just a casual conversation about sunglasses yeah we need to look for him no they're too expensive just chief ones are as good at blah blah blah talking about sunglasses and then like man for two weeks every single ad was sunglasses and I hadn't searched on sunglasses and I hadn't written you know email on sunglasses and so the paranoid among us might begin to think that some of these devices are listening to conversations but maybe that's just my paranoia coming through new pipe to tutorials I do so him need to make new pot tutorials I've got a pretty full plate right now but it will be on the list although I'm night before I did the new pie's I might do ESP 32 because there's some things that are then pretty excited about let's see I like having the headless pipe yeah on the PI a way you can do it it's just SSH in through putty and then just operate through the command terminal or I will say that you can run VNC that if we look over here let me see you see we have this VNC server and that allows you to have a remote desktop where you can have the PI desktop and that gets rid of a lot of the cables and it's a pretty snappy interface so if I was going to do something with the PI I would probably do it with the term and if I didn't do it with the terminal I'd do it with a remote desktop okay let's see I like I agree about the pie I help teach electronics at the grammar school and pie frustrate students yeah that's what I find it's the pie frustrates the students and even things like trying to get your new art working or your ITC working they make it too hard also at some point when they introduce Bluetooth it broke my old UART programs we're kind of like the I don't remember exactly what it was but it was like the USB UART was not playing well with Bluetooth and it was really really hard to get past that maybe they fixed that but I just found a lot of things very very troubling okay Stoneskin has never had problems with the SD cards because he uses genuine SanDisk I always think there's nothing more expensive than a cheap SD card okay so I agree use a good one what is your opinion about using programming grasp with Microsoft House T dashboard I really don't like anything about Microsoft and so I am trying to enter the post Microsoft face of my life the one reason I'm on Microsoft right now is this nice broadcast software runs on Microsoft and not Linux but if I had a Linux alternative to my studio I would be out of Microsoft for good okay OPO hey man how's it going buddy glad you were able to fix the audio yeah that was kind of that was kind of embarrassing I'm glad you guys came back and didn't hate on me about that you understand if you're on Microsoft things like that are going to happen and they're going to happen at the worst possible time we're using Raspberry Pi with camera to do meteor survey okay Ron James jr. I like that idea if you're using the PI as a way to connect with a camera I can see that okay that is an area that I see a niche for the PI if the PI supported SATA in SSD I think it would be much more useful I agree and even I would kind of say the same thing about the about the Nano man I love having a nice neat little box like this but wish I could add a platform that would add like an SSD or a real like a laptop hard drive as a board where you connected to a slot and not run this doofus USB cable okay I wish that you could integrate a big hard drive into this thing okay so let's see where are we nice okay nice to see you again Cisco Chris hello for people googling OSB oh man did I say it wrong Chris robo did I say it wrong thanks for correcting me it's open broadcast software OBS okay and that is pretty impressive it's free it runs on Linux the problem is it doesn't run on the PI because it needs OpenGL Luke I've been watching through your Raspberry Pi tutorials that you made like four years ago yeah it's still relevant I think there's a few things like you have to manually manually enable SSH and at the time you didn't have to so that's throwing some some things off but you can probably still learn some good stuff about the PI there okay opal man how's it going I've got a big cold glass of buttermilk oh man opal buttermilk oh yeah now opal I believe you're from Africa you got to remind me what country you're from now did you buy the buttermilk or did you make the buttermilk okay cuz when I'm in Africa man we buy milk and then we let it turn into buttermilk so I'm wondering what you're doing nothing is more delicious it's delicious than well what do you call it mas mala mala is that what you call buttermilk there's kind of a rotted milk over there I think it's called mala and I love that Cisco I think we're a spy's design for a project related graphic and controller which cannot do it with a normal controller okay I think there's a place for it it's just I haven't found it so far does anybody see do you guys not see me am I not here do you guys really not see me tell me if you see me or not all right maybe I should make myself larger you know I don't not gonna make myself larger okay yes okay why I bring computation to the third world well like man one thing that has made a huge difference in the standard of living in the third world is cell phones everybody has a cell phone like if you think of running water electricity and cell phone people will choose cell phone over running water and electricity so throughout the third world almost everyone has a cell phone even though they don't have electricity and even though they don't have running water you say well how do they charge their phone well it's a business opportunity you go down to the local phone charger you give them a few shillings and he charges your phone for you and you buy service a shilling at a time like you can buy 10 cents of airtime okay but the thing is to have people be able to communicate greatly increases efficiency and when efficiency increases increases it brings the it kind of raises the whole everyone's boat raises so I think technology has been a great thing as far as cell phones in the third world in computation the same thing to be able to interchange documents electronically record-keeping and stuff so I think there's a place for computation in the third world I just think that people that don't spend extended time there don't understand the challenges associated with it great for MQTT broker okay hey hola sia Brian from Kenya all right chrome and edge not showing anything on PC I am sorry man I do not know what is going on over there in Kenya although I love Kenya I spend a lot of time into khatallah Kenya been up to Merrill all and visited the Samburu tribe which are probably one of the most remote people groups on earth beautiful people the Samburu people sorry to hear about your dogs by the way very sad oh are you talking about my dogs with rabies yeah if you're talking about my dogs with rabies that was very sad they they became rabid foaming at the mouth and they bit my staff and then I couldn't find everybody got dog bit and then I couldn't find the serum right and then when I finally found the serum then it's like is this stuff really real so that was very scary they're still taking the shots by the way they're still in that rabies shot things but I think we're past the point of danger I think we're probably to the point that the serum was real okay we got from micro Beano says use Firefox say the audio is working hey okay yeah how's Buster for our PI RB Raspberry Pi for buggy I don't know I haven't used Buster and I'm not sure what that is I got him now to go to Windows instead of Linux okay lesson on ESP 32 I'm thinking about it okay we've got some real good comments here can you do a setup tour man so home to set this thing up it's just like you download the noobs image you plug it in and then the desktop opens and that is pretty straightforward and I think there's been a lot of instruction on that already yeah Randy I'd like to do is yes p32 Nick uses his Raspberry Pi to run the octo PI on the 3d printer okay I can see I can see that let's see I will have to try something like that dream of something just for Echo okay still some interest in Echo here again I'm kind of like the grumpy old man who doesn't like my electronic stuff listening in on me okay perhaps there is an OS B also okay Chris oh okay I see what you're saying love to see CubeSat projects and tutorials especially RF communications hey I'm not doing cube set but we do have this edge of space stuff where we send high altitude balloons 220 thousand feet above the Earth's atmosphere see the blackness of space and that's really cool projects if you guys are interested let me know I could do a livestream where I show you our Eagle 11 which will be our 11th spacecraft they kind of peel back open the hood and let you look under the hood and see how that thing goes we stream video live video back from space with that thing John uses the PI 3 B for 3 printing to my Prusa I can see that okay very good I see you're fine see you find good pie needs a decent IO port and stop trying to be a desktop dragon Dodger yes yes that is very good raspberry pie stop trying to be a desktop because if I want a desktop I've got a desktop and I've got an old desktop and I've got an even older desktop and then I have three Chromebooks I have so many desktops I don't need another desktop ok what I need is I need an ability to interact with the outside world and an easy way to turn on and off and I need something where the SD card doesn't become corrupted very very easily okay let's see Mike says he sees me you guys say that you see me fine there seems to be a disconnect between learning to use the PI versus the PI to learn other things Jim I understand what you're saying that's a good point Opel says it would be great if there was a way to use external hard drives for the Raspberry Pi I agree I really agree with that man I want to get I'd like to have a little board that you know was towered below the Raspberry Pi and I would like it to have a solid-state drive on it and I would like it to go into some sort of slot where you're not running dufus cables okay that's what I would like to do a live video from space sounds cool job that is what we could do though is I could show you kind of what we got going on our Eagle 11 and we're a ways from I mean we did a launch at the end of the last school year and we're always from doing a launch because I don't want to just go run things up I want the students to learn so they're learning Linux they're learning Internet of Things they're run learning RF communication they're learning ham they're learning FAA FCC they're learning the practicality of a real system because for us to go to space we have a hard legal limit of 4 pounds if we have a hard legal limit of 4 pounds and we want a broadcast from space we can't send a car battery up there we have to do it at low power because of the weight restraints then low power that turn into high-gain antenna high-gain antenna turns into pointing CC it's a real-world problem where you have hard limits hard legal and hard physics limits that you're up against and then you have to engineer a solution that works and so I think this high-altitude balloon thing is a most excellent learning experience but that is just me yes I saw that balloon sat very good why video yep what happened to the Jets and nano tutorials kls you get one a week man you get one a week I think I've released one on Saturday the next one will be this coming Saturday I will be doing it as a as a premiere so I'll be there in the chat room with you as you go along with it how many of you guys have got the Jets and I know it seemed like it seemed like you guys were really interested there were some people that got that and I've got some really crazy things in my mind to do with the Jets and nanos some I will be able to show you and some what some I will be doing in the secrecy of my barn because I don't want people to kill themselves with jetson a no but it's just there's some crazy ideas I have about some neat things I will do with that some I will be able to show you some it will not be able to show you just the Raspberry Pi for have true Gigabit Ethernet I do not know that I really do not know that okay so guys I think the comments seem to be kind of slowing down here we've had a good chat I did not put links in the description down below to the Raspberry Pi 4 because I only suggest things to you that I really like in and guys I don't get stuff free to then try to sell you and so people offer me a lot of free stuff usually I turn the free stuff down and I'm not just about trying to get you to you know buy from my affiliate links I'm not linking this stuff because I'm not gonna recommend but recommend it because I really don't know what to do with it those of you guys who are using it and loving it great man that's good I'm glad you found your niche with it but I'm just not seeing for me where it's going so I'm not able to really very well recommend it to you and so no affiliate links down there there are links to the Judson Nano and I am very excited about that and that's kind of where my energy is going right now I finished up the Arduino ímu tutorials and you're getting those once a week so the tutorials I'm making now or or on the Jetson Nano so we're gonna have a lot of stuff I'm still trying as best I can once a week to maybe have a livestream with you guys okay kls I'm waiting for mine to arrive now I'm really curious on what you plan to do with out of the Jetson on oh yeah well my path is first of all you guys don't hate me the Jetson nano tutorial series said for absolute beginners so I'm gonna take you step by step by step so don't get mad if the first few lessons are teaching how to use the Linux command line okay because as I do things I want you to understand them I don't want you just copying and pasting my command so you need to learn how to make your way around the Linux system from the terminal then I'm gonna start teaching you some Python you need to know how to write simple Python programs then our path into artificial intelligence is going to be open CV an open CV is a library for Python that puts you between the camera in the screen and so you're in there and you read a frame and then you do crazy things with the frame and then you feed it out so you're sitting there in the middle and there's all types of really interesting things that you can do when you're sitting there so my artificial intelligence work is going to be focused on open CV right now I'm going through all the nvidia tutorials and the demos and stuff but the problem is like they set up a jupiter notebook and then you open up this window and then it runs this software and then you sit in front of the software and you train it the difference between thumbs-up and thumbs-down and then you finish training and then you hit run and then you go like this and it says thumbs up and you go like this and it says thumbs down now I see that it's really interesting and useful but I didn't write the program I'm just using the program they wrote in a lot of times it's like in C and compiled and all this crazy stuff and I can't take that and now make it like what if I had a nerve gun and if I went like this it would shoot the nerf gun at someone or something like that you see like where I'm doing something in then it's doing something in the real world well I can't do that because all I'm doing is running their software and they are great people and I love what they're doing but I think they're a little out of tune of a little tone-deaf of seeing that if someone isn't already an expert in artificial intelligence they're not giving them an easy path into it so we need to work our way into where we're not running other people's software but we're able to run software ourselves does that make sense okay Nick thanks for the live string okay Nick we will see you later check out the in explaining computers Channel if I remember he highlighted a tray that holds a drive in a pie Buster I kind of remember that but I'm wondering if that was really a raspberry pie earth that was a rock pie or one of those other ones I don't remember for sure okay mohamad press it T Oh forgive me you guys for my pronunciation hi I want to start with raspberry and it will start with raspberry pi for what do you think is it better if I start with them if you're gonna start I don't know I mean might as well get the four right but it's not that much difference between the 4 and the 3 I like the zero the zero is the one I want because I can do it small okay let's see okay it seems like you guys are needing to get on with things and we've been here for like 42 minutes and so this is probably a good time to wrap this thing up you guys again really appreciate you guys that are helping me out over on patreon you guys that are helping me it helps me to deliver a better product to you plus it gives me encouragement that in a tangible way that these videos means something to you guys because the one thing I don't want to do is waste my time and when I see that tangible support from patreon I know that I'm not wasting my time hope you guys have a great day you heard the bell ring I'll have students coming in here in a minute I am Palma quarter from top tech boy comm I will talk to you guys later
