I developed a quadcopter with a custom flight controller, programmed in Python (@micropython), that can efficiently run on a $4 @Raspberry_Pi Pico microcontroller! Check it out: github.com/TimHanewich/Centa…

Centauri logs telemetry every flight: battery, actual vs desired pitch/roll/yaw, motor output. Chapter 8: the Python (@ThePSF) tooling that unpacks it, and a real crash it helped me diagnose. medium.com/@timhanewich/full… #FullStackFlight

So 10th grade geometry ended up coming in handy. At least as long as I don't know how to automate this in Blender.

Chapter 7: the software that turns "pilot moves joystick" into "drone changes pitch." Reads @Xbox controller inputs, packs control packets 20x/sec, displays telemetry back. Any lag shows up instantly in the air. medium.com/@timhanewich/full… #FullStackFlight

Skipped custom transmitter hardware. Instead: an @Xbox controller + laptop + a cheap radio module = a fully capable, bidirectional transmitter. Chapter 6: how that platform works. medium.com/@timhanewich/full… #FullStackFlight

Another (minor) addition to the Centauri ecosystem: Link Monitor Just a small handheld device to check reception at range of the control commands being sent out by the transmitter. Wiring diagram done. Now to design the device. github.com/TimHanewich/centa…

Programming the flight controller was, hands down, the hardest part of this build. Picked @micropython over C/C++ for readability. Chapter 5: the boot sequence, the PID loop, and the sensor reads. medium.com/@timhanewich/full… #FullStackFlight

Designing a quadcopter airframe is harder than it looks: prop clearance, IMU placement, antenna line-of-sight, all in one printable body. Chapter 3: Centauri's design, plus 4 antenna setups I tested. medium.com/@timhanewich/full… #FullStackFlight

Rebuilding Centauri last night after the heavy crash. Upper + Lower levels replaced!

Tonight's effort: rebuild after the heavy crash from last weekend. Lower and upper level plates replaced completely.

Build your own drone AND transmitter, and you own how they talk. Centauri uses 4 packet types over a slow radio link. Chapter 2 breaks down the exact binary layout. medium.com/@timhanewich/full… #FullStackFlight

Centauri is 3 pieces, one loop: the quadcopter (self-correcting, PID 100s/sec), the transmitter (@Xbox controller + laptop + radio), and telemetry software. Chapter 1, the map before the weeds: medium.com/@timhanewich/full… #FullStackFlight
