Hello!
This is a schematic i made for my model rocket based on an MPU9150, BMP280 and ATSAMD21, along with an swd programmer to flash the chip. Would like to know whether all the connections made are fine, and how i can add servo control along with pyrochannels using mosfets

Thanks!

Its a capstone project.

 

First, the rocket in near Cosmos will take the one side up to 600 C or higher (1380 W/m2) whilst other side -273.159 C..... So the standard solution is to connect the both sides thermally and chose the place where electronics may stay alive. Or insulate the electronics fundamentally and apply the two powerful thermoelectric (Peltier) coolers, where computer will choose which one this moment is able to cool anything and which looks toward Sun.

Secondly, in the Space Tech Expo where I am frequent guest they advice to use ceramic PCB, however not very much clear why. At least Rogers PCB was for me the eureka, I even registered the Patent about their use. Its clear - their normal frequency range is up to 40 GHz and more, and some of them are rather thermo-stable, may survive a 300 C and heavy gravitational overloads.

Thirdly, the Space irradiation in X-rays, gamma and particle beams is never less than 0.1 REM but at Solar flare happen may get the 5 REM or even more. To honest, only vacuum tubes may stand such awkward doses. Therefore a certain anti-radioactive ecrane must be applied as the law. What, that is another question what I have difficulcy to answer, because thye Cosmic Rays have enormous energies, from MeV to GeV scale. Otherhow the any kind of RAM will become faulty and uP will got shut off.

Last but no least is gravitational overload what may happen be 10g or larger. Means all the components must be glued adittional to soldering and glue must be hard enough. The same about connection wires which occassional may undertake the centners of forces but must withstand it.

That’s exciting. A group at the university I retired from did a “guided missle” which was very challenging but it was about 10 years ago and the CPU power, sensors, and actuators available have improved dramatically—they’d probably get further today.

I’ve moved your thread to the Homework Help forum. AAC rules concerning helping with coursework limit the type of assistance to guidance with your own work. Because of this, all such posts must be posted to the Homework Help forum to make their nature clear.

As it turns out, you will probably get more and better assistance in this forum in any case. Best of luck with your project and don’t leave the documentation to the last moment, it’s very important.

Hi!

Its a model rocket flight computer for TVC rockets i want to build. Thanks for the large amount of advice though!!
