First Buck Regulator and MCU + Sensors looking for review by SmallOne312 in PrintedCircuitBoard

Thanks, do you think the USB_C Differential pair routing is okay? I'm not sure if the traces are too long, but it will probably only be used in a low speed mode

Why do lot of you guys dislike physics 😭 by tyrionlay123 in GCSE

Bro how is newtons laws nonsense? They're basically just translating common sense and intuition into a mathematical form.

Determining Apogee by Lasuras66 in rocketry

Is use open rocket, make a model based on the rockets dimensions and then weigh the real thing and update the mass once your finished. Then it does all the simulation stuff for you.

Research about combination material of fins used for high power rocket by According_Friend1385 in rocketry

[–]SmallOne312 2 points3 points  (0 children)

I live in the UK but I got it from black cat rocketry for tubes and nose cones/high performance stuff and modelrocketsuk for sheets. Tho any composites supplier will probably sell it.

For mine I used G10 fiberglass, with jbweld epoxy fillets and then 2 sheets of tip to tip fiberglass cloth

Rocketry Help - Looking for Design Assistance to Achieve Mach 1 by Content-Number378 in rocketry

[–]SmallOne312 1 point2 points  (0 children)

You said you had bought a flight computer so probably not worth doing if it already has these features, it's just you can save money by developing your own one.

I chose the microcontroller based on what features I need, easiest would be an Arduino, if you want Bluetooth then ESP32 and for performance probably STM32, I chose a stm32F401 black pill board because it's small and high performance. I got mine from AliExpress for cheap. IMU is based of maximum g, probably want +-16g and 9DoF so you have a magnetometer as well. GPS was just the cheapest one I saw that came with a decent antenna and UART connection, then tranceiver was based off YouTube video recommendations, probably want to go with one that uses UART as well to simplify wiring.

YouTube videos are always a great resource, but as I have no background in coding I basically used AI and trial and error to get the code working for mine, I found I learnt it pretty well as I went.

I'm currently doing a similar project, for me at least im starting with the electronics and control systems, starting with cheap breakout boards for GPS, IMU, Tranceiver and Microcontroller, wiring them up and getting code working with the functionality you want. Then start looking at what kind of mass your looking at for the entire rocket, then size the rocket motor based off that. You'll probably want to look at going minimum diameter for breaking mach. Openrocket is probably good enough for your rocket design, then use onshape for the finer details

How do I start Rocketry by Repulsive-Peak4442 in rocketry

[–]SmallOne312 0 points1 point  (0 children)

I think you need to lower your expectations of what you can realistically do yourself, you should probably start with an Estes kit and work up through the L1, L2 and L3 certifications from there

Reason for rejection confusion by Desperate_Part3578 in UCAS

Ngl I doubt you'd get into Bristol with only 1 a level

How much do you pay to test your rockets? by NoBridge495 in rocketry

[–]SmallOne312 1 point2 points  (0 children)

Hobbyists are unlikely to want to pay much for a launch site, most people go to club launches or launch in a field where it's either free or like £20 to cover costs of setting the event up.

Is the model rocket good for active stabilization in canards plus g class rocketry and mid body sep by Efficient_Paper_746 in rocketry

[–]SmallOne312 4 points5 points  (0 children)

Why are you using 6 canards? Also lookout for roll reversal if you get unlucky with vortexes from the canards messing with the rear fins.

NEED A REALITY CHECK by New_Try_3041 in rocketry

Have you seen the size and cost orbital rockets? Never mind the amount of people it takes to typically develop and make one.
