Drones flight computer

@rabail What do you mean by computer? Also, what country are you in as many countries have rules about licensing and where you can fly. I recently left an island that was several hundred miles long but it was almost impossible to find a legal place to fly due to endless water plane landing strips.

This is a DIY drone tutorial. This is based on ESP32. You will get here everything including code, circuit diagram and PCB layout. This DIY drone is small in size and can be built using easily available components such as ESP32 modules, MPU6050 IMU, coreless motors, and plastic propellers. This drone can be controlled using a smartphone over WiFi.

@aliarifat In Canada, I don't know if that is legal.

I think both points above are really valuable using off-the-shelf components like ESP32 or STM32 makes it much easier to experiment, but at the same time, regulations can’t be ignored depending on where you’re flying.

From my own experience, the biggest challenge in building a flight computer isn’t just wiring up the sensors or getting the code to compile it’s tuning the PID values and making sure the drone stays stable in different conditions (like wind or sudden throttle changes). Even small differences in frame weight or prop size can change how the flight controller behaves.

Has anyone here tried combining GPS + barometer data for smoother altitude hold? I’ve been reading about sensor fusion with Kalman filters but haven’t yet implemented it myself. Would love to hear if someone has tried it in a DIY build.

@aliarifat I bought this unit assembled, seems well thought out. Been flying this inside my home. Just something to tinker with. The github codebase requires ESP IDF to build (I used v4.4.5).
