Schematic Design - Landing Model Rockets Ep. 4

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.

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!

[@Fffffffff3]

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!

[@samrrivera]

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 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!

[@danielreyes7297]

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!!!!!!

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.

[@MichaelLloyd]

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).

[@brendanrobertson7966]

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.

[@AJMansfield1]

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,

[@danielreyes7297]

57:42 is there not a debug function similar to Visual Basic? Also, I seem to remember a run function

[@chibiconsulting]

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.

[@FilipeFontenele]

This really helped me a lot ! Great Job sharing this info. Looking forward for the next steps !

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)

[@wildboar2598]

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.

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?

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.

[@KerbalChris]

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?

[@bonelessostrich8558]

im more used to using EasyEDA than Eagle and i was wondering would this work in EasyEDA? Edit: later self here ive tried it and yes it will actually work with EasyEDA

[@charliebrady3214]

do you know what he meant by he made lots of mistakes what were they

[@vovanikotin]

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.

[@noa.sendlhofer]

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

[@noa.sendlhofer]

And you can combine the PCB and parts order, so you'll just pay the shipping costs once :)

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?

[@colinwarn4606]

Can anyone explain why sensors like the barometer has a capacitors and resistors? And how does one know whether a sensor needs a capacitor/resistor, in addition to knowing what values for each they need? My guess is that there’s a data sheet that usually tells you if a sensor needs these things, but I’m wondering if there’s a way one can figure this out without necessarily having a data sheet.

where to connect chip select of flash chip to processor ? I mean, to which pin of the processor, the chip select pin will be connected

What were the reasons behind the shift from ATmega328 to MK20DX256VLH7? Is it possible to use the less powerful ATmega328 for this project - will it work?

[@BPSspace]

It's possible, but the main issue was program space. Especially with some of the bulkier SD card libraries, the ATmega328 didn't leave a lot of room for expansion as the codebase got larger. Figured it was better to just overpower the board rather than try to prove it can be done on the 328.

​@@BPSspace Considering that I don't have a lot of experience with programming, designing computers and stuff like that I have decided to start with Arduino Nano and work on some elements of a rocket individually and improve them graually. When ATmega328 won't suffice my needs I will move to more powerful versions with more memory. Thank you for the answer and all you do!
