Macropad-3-keys-1-knob
Custom firmware for a 3-key + rotary encoder macropad (Based on IC CH552g) (https://hackaday.io/project/189914)
AeroVECTOR
Model Rocket Simulator oriented to the design and tuning of active control systems, be them in the form of TVC, Active Fin Control or just parachute deployment algorithms on passively stable rockets. It is able to simulate non-linear actuator dynamics and has some limited Software in the Loop capabilities. The program computes all the subsonic aerodynamic parameters of interest and integrates the 3DOF Equations of Motion to simulate the complete flight.
