COIL WINDING MACHINE
An arduino based solenoid coil winding machine, able to set coil turns by using a rotary encoder by using low/high resolution mode, in which one pulse from the encoder corresponds to 4 turns / 1 turns respectively. Press start button would start the winding process, and all turns settings + winding progress are displayed on an OLED screen.
little words from Dimitri: please forgive my poor mechanical design and wire management skill
BLDC ESC
Sensorless brushless motor driver based on N76E003AT MCU, with 5A BCE output @8.4V, withstands up to 8s (33.6v) lipo battery and 200A of continuous current output. (Right hand side picture was from an older version, see below for newest PCB, in which ground plane size were optimized for larger current sink.

AM32 ESC
Brand new AM32 open source firmware based Brushless motor ESC! with a complete different four layer PCB design , 32 bit STM32G071 MCU, and INA199 based current sensing circuit for more precision. Such ESC would be able to handle more current and allow users to flash their own firmware by creating a fork of the AM32's github project: https://github.com/AlkaMotors/AM32-MultiRotor-ESC-firmware
The PCB had been sent to manufacturing, will be available in next week.
