I've decided, while waiting for the pressure sensor for the altimeter, to make a homebrew timer based on PIC12F629. It must handle drogue and main 'chute deployment (e.g. 2 outputs). That means I must put two giant MOSFETs and a super-sized 1mF (that equals to 1000uF) capacitor. I think it'll be better if the MOSFETs and the capacitor are on a "high-power switch" board, seperate from the timer PCB, but there comes another problem - where will the seperate high-power switch get its power from - directly from the battery or from a cable between the timer and the high-power switch? Or should I put everything on a single PCB?
