Dev blog 3 i found a new solution for the sensors i was planning to use :). While scrolling on aliexpress for parts i found a +-16g IMU that has a built in pressure sensor, these are the two main datapoints that i am trying to collect with this flight computer. because of the part that i found i decided that i will probbably add some type of servo control that can for example deploy the parachute at apogee or something else. the module is called the MPU-9250 and it has a 10dof imu with a bmp280 and digital compass which could show us how the rocket rolls throughout spaceflight. i belive that 16g should be enought for smaller model rockets class d/e from research online so there shouldnt be a bottleneck. i finshed the schematic for the charging module however i am still deciding if i should integrate it into the pcb or solder on a module. the goal is to make it low cost so that anyone can make it as cheaply as possible without any drawbacks on performance. live data transmition isnt in my scopes right now because on short rocket launches it isnt really worth the extra hassle and parts for me at least. maybe in a future revision i will add a gps chip for live tracking however i want to start a prototype first. Next step: order parts and assemble on breadboard.
