Me and my team(ITU Rocket) joined 10th Intercollegiate Rocket Engineering Competition on 25th of July, 2015. We designed and built solid rocket engine, main computer of rocket, rocket mechanical parts.
Main computer circuit design process:
Firstly, we studied past year competition reports. Then, our rocket primarly was designed and how our rocket recovery and which compenent need for recovery. These problems were determined and dissolved.
Secondly, We determined the microprocessor and electrical subsystems (like sensors, voltage regulators) with controlled datasheets. And these sensor were tested on the breadboard.
Thirdly, I designed sensor breakoutboard and communication ways at one main board.
On the other hand:
I designed seperated pyro board, and 900mhz communication breakout board. I have used DipTrace PCB Design program. All boards were 2 layer. It was enough for that job. I can recommend for that.
Then these boards were manufactured by Baski Devre PCB Company which is our sponsor. I also worked for fund raiser and contacted that pcb printer company.
