I’m somewhat done with the hardware. The flight computer arrived, and the selfdesigned PCB worked on the first try! I haven’t tested everything yet, but the buck-boost converter, battery protection, LDO, MCU, radio, and buzzer all work.
I also almost finished 3D printing the rocket, only the body tube is still missing. I’m shooting for a dry mass of 170 g, and I’m well within that budget, so everything is going well so far.
Next, I will be working on the communication protocol between the rocket and the ground station, and then write the firmware for the rocket.
