3D air mouse based on STM32 - Can be used for controlling CADs and every other manipulation in 3D space. Is based around STM32L452, IMU LSM6DSL (gyroscope and accelerometer) and Bluetooth low power module RN4871. Also contains battery management system for charging internal battery and also powering itself from this li-po battery (around 40 mah). Battery can be recharged via USB type C which can be also used for streaming data from accelerometer.
A Raspberry Pi Pico display replacement for the Roland MT-32, with a modern TFT/OLED, MIDI VU meters, and MIDI buffer-overflow protection.
