DAC ADC PWM IO
STM32 microcontroller with lots of periferials such as ADC, differential ADC, Input Capture, PWM, USB, Encoder, DAC, Digital Input, RTC, CAN-bus + Alarm etc.
hexaGenMini v1
Open-source USB MIDI-controlled signal generator built with Rust (Embassy) on RP2040 + AD985x DDS for education, labs, and music synthesis.
ESP32 PCB
This project involved the end-to-end design and development of a compact, low-power IoT system using the ESP32-C3-02 SoC and integrated TP4056 Li-ion battery charger. The goal was to create a reliable and modular platform for wireless environmental data monitoring, powered by a rechargeable battery with onboard protection and USB-C support.

Monotron 002
A modification for Korg's Monotron Delay, which makes it accept standard Eurorack CV voltages (Pitch, Gate and Cutoff CV). The mod also provides an option to power the monotron via micro-USB.
RingOne
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.
dcpower
