When testing altimeters earlier, were not going well, that's why the days from the date we are dedicated to design your own.
First we designed a circuit that is a schematic drawing from scratch, I used 4 operational and for that reason, 2 integrated (each has 2 integrated operational). But when compared with last year's design, which once went well but not our disposal it because the oxide is responsible for ruining it, we noticed that the design had 2 operational, ie, a single integrated diagram being much smaller. Thus
recreate last year's circuit in a breadboard , as it was more compact ( important feature when putting it inside the rocket), and we wanted to try, but not our disposal a sensor pressure as that needed . Also
knew the circuit worked the results obtained last year, and although we could not test in the breadboard, printed circuit board to make in the future.
