I was watching BPS during a physics lecture, and my teacher saw and was like "Oh, is that the kid that makes rockets like SpaceX" Joe, ur infecting the science industry...
I know Im asking the wrong place but does anybody know of a tool to get back into an Instagram account? I was stupid forgot my login password. I appreciate any help you can give me
No man it's not at all boring. You are one of the best teachers. No one can become one unless he has started and taught himself from ground level. Shows the hard work you have put in. Thanks a lot for this series 👍👌🤘
I always find the EDA phase of schematics soothing. Just the organization and percision after the tormented pencil and paper schematics are done...ish. and watching someone else do it is theraputic! Awesome video!
Totally fine with the level of detail too. The length of the video doesn’t matter. It’s not dry or boring. It’s a pretty good representation of how this stuff works. I can’t believe Im gonna make a computer and give it instructions!!!!!!
What a great video! When I first saw it was around an hour long, and I have no intention of making the board, I didn’t think I’d watch the whole thing, but it was fascinating! Thanks - your channel is superb!
This is everything I have plan for this year. Developing my own computers, launching and landing a rocket, developing other autonomous vehicles to monitor the flights. Amazing work! Personally my first few computers will probably be based on atmegas. Once I've mature the code I'll move it to something 32 bit.
I have been using Eagle for over a decade. In the pre-Autodesk days (Cadsoft Eagle) I used busses alot. There was a time when I wasn't making schematics and I lost track of some of the more efficient ways to draw a schematic in Eagle. Like using Nets. I just made a little board and ordered it today. I wired every point to every point as if I was using paper. Then I watched this. Facepalm but very grateful that I came across this video. you just knocked hours off of schematic making. Now if you can just come up with a way to speed up board making (placement and routing).
I really hope your company takes off, you would make a great competitor in the space industry, you’re not afraid to learn new things, and articulate your thoughts very well
27:32 this kinda stuff is right up my alley. Im an electrician by trade and I have experience with Visual Basic. Ive made spreadsheets and word documents imported one to the other, we made databases too. One for a hospital and another for a school. Building electrical components is literally my missing link.
Would be cool if you started a Podcast about your ideas and experiences on these rockets. I find myself listening to your videos more often when I’m at work now. Keep up the good work!
Truly love the videos you are putting out, makes me want to start building too! Request: When posting long videos like this I think it would be really helpful if you add a few bullet points to the description. This will make it a lot easier to navigate.
When he said that the anode was positive my mind immediately went to my high school chemistry class where my teacher taught us that CAThodes were PAWSative
By using N channel MOSFET to switch the low or ground side on the pyro connections, this opens up a potentially serious safety issue. Since the 12V terminal is always active when powered, a loose wire on the ground side could then come in contact with almost any component and discharge the Pyro through ground. That short circuit could occur with almost any circuit on the board which would in addition discharge a high current through the component and damage it as well. The better method is to use a P channel MOSFET to drive the 12V side and have it return to ground on the other terminal, this way the 12V potential is only exposed when directed by the micro controller.
Thank you very much for making this video, and making it so easy to follow and understand. My Uni course requires quite a lot of use of Eagle, and I unfortunately missed all of the tutorials for the software due to illness, so it's great to get some understanding before I really need the software.
It'd be interesting to see the viewer retention stats on this video lol. I must admit that I've paused this halfway through and hope to get back to it but all the different combinations of letters have got me a little lost which is frustrating because it's a skill I'd love to learn. Maybe once I've had my ADHD assessment next month I can come back and follow along with this better having started some medication to help focus my brain 😅(It's a great video btw, you've done a really good job of displaying this stuff in an approachable manner - it's just a tough subject lol)
Finally learning something! Thank you for all your work. Your subscribers don't increase by much. Hopefully, more enlightened ones notice this channel and subscribe.
I understand the need for more compute power, but I will say, I was a little disappointed to hear that you are changing out the microcontroller. I was actually looking forward to seeing you really push the limits on the ATmega.
Just as a suggestion: Try once the EasyEDA/LCSC/JLCPCB combo. It's just as easy as Eagle but offers way more stock libraries. For the last year or so, I designed dozens of sometimes really complicated projects and I only once had to draw a custom footprint. It also offers you the so-called BOM tool. It creates a file of all the components, that you can directly upload to LCSC and it will automatically put all the components into your Shopping cart. I really enjoy that :) Greetings from Switzerland
11:30 Note, it should actually be 3V0 (with the digit zero) not 3VO. That digit after the V denotes the decimal portion of that rail's nominal voltage e.g. If it was a 2.7 volt rail it'd be called 2V7, and if it was a 3.3 volt rail it'd be called 3V3. In this case the nominal voltage is 3.0 so it's labeled 3V0,
protip mr musks love child; if you wanna delete an entry in a text boxes "remembered stuff" dropdown, you can just arrow key down to it and hit the del key. Surprisingly it's handled correctly in almost every instance.
47:57 I think I got that right? The voltage divider drops it to 1.1volts. I (total) = 12 / 1,100,000 then voltage drop = I (total) X 1,000,000 = 10.9v drop. 12-10.9v = 1.1volts. Just starting out with electronics.
Also using linear LM7805 for 12v to 5v convertion bad idea for rocket, LM will self heat, reguire radiator for heat dissipation, this is some excessive mass. I recomend you to use dc dc buck converter, they are more efficient and almost no heating.
Would be cool to add a couple of Arduino cams that are triggered by one of the spare pins on the flight computer. It might be lighter and more space efficient than the little cameras you use atm... plus you don't have to go through the ordeal of hitting record a bunch of times.
Hi Joe. Just out of curiosity, I understand that a solid rocket can not be throttled, but, in theory is it possible to create a device that can interact with the engine exhaust to either redirect it or at least disrupt the laminar flow of exhaust gases to reduce the x-axis force of the thrust? Would placing such a device in the exhaust path of the engine be legal? If there were a failure of that component, the thrust could propel a piece of that component at a dangerous speed and in an unpredictable direction. I'm not a certified rocket builder, so I am not familiar with what is allowed and what is restricted.
Hey Joe! I know this video’s a little old but I was just watching today and I had a question. How do you know what passive components are required for the various sensors if you’re not going the breakout board route? Like how do you know exactly how to re-create the important parts of the breakout board on your PCB? Is it in the data sheet for the sensors? Thanks so much for the super informative content!
Why is the voltage divider Vout 1.09 Volts? isnt that kind of low for an analogRead input for a logic board? Couldnt someone get a more accurate read of the voltage when they use a voltage divider that has a Vout of 5V into the analogRead of the logic board?
Great video, very interesting for someone who currently has alot to do with that through studying. Never thought I'd ever understand all that, but I do now:O Just the header pins you chose made me cringe a bit. Why not put the buzzer from the TX2/PWM to a PWM only GPIO and then you can use the PWM/RX2/TX2 lines for the header, would allow both usage of the serial port AND three PWMs. Now only one PWM is provided:(
not related to the video but have you thought about making custom rocket nozzles to increase the predictability of the thrust of the rocket motors? I have seen some 3d printed (plastic) nozzles and bells that seemed to hold up to at least one fire. I bet if you put a thin coat of plaster on the inside it would ablate and live a lot longer. not sure how a second burn would work.......
So for landing model rockets could you have the first stage bring it up then when the engine is out it is discarded along with the fins at the bottom so smaller fins at the top can stabilize it for the flight down, then at a certain point after the rocket reaches its apex of its flight then the next engine could fire, maybe with engine gimbal for a safe landing?
Just a suggestion: Why not connect the LED Anode to 12V and recalculate the resistors? That will make the LED lighting smooth and no extra heating to the Processor. Now you will have almost no light from two colors. Anyway Thanks for all sharing! It is now more than 30years sins I designed a PCB. With education. And u do it without! My interest is Control loop design. Need to look to your other videos!
Did you ever think about engineering a micro rocket engine. Powered by liquid oxygen and RP1? Have no idea, whether a micro rocket engine is possible due to size limitations. In my opinion it would be more easy to land a rocket, if you can stop and start burning continously... Btw, I really like watching your videos. Thx for answer Florian
One hour of rocket science? Best day ever
One hour of Electrical Engineering.
I was watching BPS during a physics lecture, and my teacher saw and was like "Oh, is that the kid that makes rockets like SpaceX"

37:42 I love this quality of electricity. The fact that OHM’s law works at any scale is elegant.
hey Alexa why did I make this video 8675309 hours long
Was funny though. Going to be a great hour!
why don't you use the teensy 3.6 (chip), it's obviously better.
@@loukask.9111 The Teensy 3.2 is already way overpowered for this task. The 3.2 is cheaper and smaller as well.
MORE VIDEOS , LONGER VIDEOS PLS
BPS.space longer is better
cant believe i just spent an hour watching probably the most informative schematic designing tutorial

With the microcontroller he uses you can use the Arduino environment. There's only advanteges

why isn't your enter pin broken yet?
sounds like you hit it with a hammer each time
Well you see, unless you hit the enter key dramatically and with a lot of force, it won't work.

Thank you for keeping this as long as you did. I’ve learnt so much.
I'm so happy! One hour video! Thank you Joe you have made my day!
WOW Joe is looking so much healthier today
I'm proud of being an early boy subscriber to this amazing company.
Just learn Eagle from this nice video. Please don't stop making videos like this one.

I understand the need for more compute power, but I will say, I was a little disappointed to hear that you are changing out the microcontroller. I was actually looking forward to seeing you really push the limits on the ATmega.
i see other videos on youtube but you do it with a true maker spirit and i love seeing that keep on going
Finally new film , I waited a long time for film. Greetings from amateur of rocketry from Europe, hope this will be a good year for you :)
Solid into dude!! I just got some Philips hue bulbs for my room and I’m loving using Alexa with them.

I don’t have money, because I am still in school and i am not working yet, so only thing I can offer you is : “Thank you”.
You are the next elon musk when you become a trillionare you gotta give every subscriber a million dollars
Joe: Buys an Alexa
Hm.. Now I have to figure out something useful to use this for
I got it, let me ask it a question every intro. Genius!
You have quickly become one of my favorite youtubers. Keep doing what your doing 👍🏽👍🏽
Joe Barnard 1-hour schematic design video at normal speed speedrun (intro-outro included)
This is, hands down, an amazing tutorial. Mad props to you!
And the meme references are great!
Fun fact: his shirt color matches the connecting lines in the computer program!
Thank u joe now ı can design my own avionics

i love everything you're doing. keep it up! if you need help with anything! I'm here!
This is a master class...Well done sir!
it took me 4 hours to go through this with you but i did it!! XD
You really helped me reach my dreams. Thank you!
How nice that now I have such a cool teacher!
I'm in computer engineering and there is no way this guy knows all of that with a music degree only.. I'm shocked.
1 hour of Benefit, worth it , thank you.
Enjoyed the video very much. I would like to have seen what the final pcb looks like
Would be cool to add a couple of Arduino cams that are triggered by one of the spare pins on the flight computer. It might be lighter and more space efficient than the little cameras you use atm... plus you don't have to go through the ordeal of hitting record a bunch of times.
Maybe want to opto-isolate mosfet gate to prevent emi back to the processor while firing charges
Ur delightful. Thank you Joe❤️
