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...
EvilTerabite exactly! Even a model rocketeer is known by many people, so cool
EvilTerabite AHHHHH
"infecting" did not age well lmao
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
@Canaan Maison Instablaster =)
One hour of rocket science? Best day ever
One hour of Electrical Engineering.
This video teach more than the first 2 years of an engineering career. I'm seriously. Thank you! Greetings from Spain!
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
I'm so happy! One hour video! Thank you Joe you have made my day!
Thank you for keeping this as long as you did. I’ve learnt so much.
Absolutely great video and Eagle tutorial at the same time. Thanks Joe!
Hi, Joe. I just want to let you know that we're all very grateful for the videos you create. We learn so much from them!
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 see you are a fan of smashing your enter key like myself...
The only thing I'll ever smash
@@TheMegaBit 😔
I hope every video that follows has this awesome quality and content - I can’t wait for my components to arrive!
Utterly mesmerizing. Fantastic. Well Done, Well Explained. Thanks.
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 one of those youtube channels that im gonna watch for the next 20 years probably
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!
cant believe i just spent an hour watching probably the most informative schematic designing tutorial
Wow, this is actually pretty helpful. Thank you for presenting and teaching in such a nice way.
i see other videos on youtube but you do it with a true maker spirit and i love seeing that keep on going
This is a master class...Well done sir!
you're a legend for videos like this man!
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
Just learn Eagle from this nice video. Please don't stop making videos like this one.
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.
This is his 5th keyboard
I'm proud of being an early boy subscriber to this amazing company.
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.
With the microcontroller he uses you can use the Arduino environment. There's only advanteges
@@danimaster6647 iirc atmega is used on Arduino mega
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.
This really helped me a lot ! Great Job sharing this info. Looking forward for the next steps !
Wowwww thanks for the effort you put in these
videos !!!!
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).
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!
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.
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 :)
you are honestly a huge inspiration
Lol I usually watch all of your videos three times to get all the information. So I'm going to have a heck of a time for this one!
Solid into dude!! I just got some Philips hue bulbs for my room and I’m loving using Alexa with them.
1 hour of Benefit, worth it , thank you.
I love one hours videos if it is Joes awesome videos!
Ur delightful. Thank you Joe❤️
13:39 “it really do be like dat sometimes”
It really do what it does👌
How nice that now I have such a cool teacher!
You really helped me reach my dreams. Thank you!
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.
Good call, I'm on it - thanks!
@@BPSspace Awesome!
i love everything you're doing. keep it up! if you need help with anything! I'm here!
Great video, great explanation!
Learned a ton!
You have quickly become one of my favorite youtubers. Keep doing what your doing 👍🏽👍🏽
Awesome video DUDE
Thank you for this great work
best video forever.
Love your style bro.
i love this serie !
You are my inspiration
Man you are genius!
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
it took me 4 hours to go through this with you but i did it!! XD
yes an Eagle tutorial!!!!
yes! I am feeling like a trooper! XD
good day sir
love your videos
make more of them
"metric is the only way" the truest thing i have ever heard
amen
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)
This is, hands down, an amazing tutorial. Mad props to you!
And the meme references are great!
Thanks for sharing...........
You are the next elon musk when you become a trillionare you gotta give every subscriber a million dollars
i luv u for this videos.
Ty for information
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
And you can combine the PCB and parts order, so you'll just pay the shipping costs once :)
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,
I love rocket science
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.
Enjoyed the video very much. I would like to have seen what the final pcb looks like
this man needs some sunshine
Joe Barnard 1-hour schematic design video at normal speed speedrun (intro-outro included)
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.
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”.
ouch alexa just burnt you hard couldnt stop laughing
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.
EXCITING......
Fun fact: his shirt color matches the connecting lines in the computer program!
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.
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.
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.
@BPS.space what books would you recommend of learning rocketry and Electrical engineering?
youtube
Hey, Joe! Check gy 87 or 88
One board include mpu6050, hmc5883l compass and bmp180 barometer.
Holy cow this is LONG, but still an amazing video nonetheless!😁👍🏽
Great Video. How's Papa Musk?
Apparently I'm a trooper 😊
In your video you said your spacing was off on your bmp280 footprint. what would the spacing be? Thank you
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?
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!
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!
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?
Maybe want to opto-isolate mosfet gate to prevent emi back to the processor while firing charges
U the man
34:44 you said you later connected cs pins to the processors, which cs pins where on the processor?
cool
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.......
Welp I’m making this board now.
I love this video and keep watching it over and over again @bps.space. I've been doing some research into MOSFETs and and running them actually off a Raspberry Pi Zero because I want Python to be my code vs. C++. Anyhow, I uncovered that you should have a Gate Resistor between the GPIO and MOSFET gate. It seems the equation for the resistor size is V / I (3.3v / 20mH) to get a 165 Ohm resistor. I'm wondering if you have started using Gate Resistors for Mosfets?
Totally unrelated but what rocket engines do you use and how do you make your pyro charges?
