A soldering reflow hot plate based on STM32

Fanpico: Open Source Programmable PWM (PC) Fan Controller

Custom RPi pico keyboard with firmware and PCB design

Lightweight ESP32-based IoT module for remote data logging enabling the collection and upload of 3D printing statistic values to a cloud server, as well as displaying them locally on a dedicated display. The project also involves extending the Marlin project by adding a custom G-code command at the firmware level.

semi-staggered 38 key split keyboard under 100x100mm pcb

A compact industrial-grade 64-channel Modbus RTU output module.

A smart thermostat built on the ESP32 platform featuring environmental sensing, e-paper/LVGL display, deep sleep power management, and multiple connectivity options (WiFi, Bluetooth, Blynk IoT).

A split keyboard with 58 keys, 2 encoders, 2 I2C displays and type C removable cables

Low profile 5x12 ortholinear keyboard design for choc/ks-33 switches

VARPA: A Variable Power Amplifier.

"Asynchronous SPDIF Mixer" synchronizes and mixes up to three asynchronous S/PDIF streams into a 48 kHz output. Running on an STM32H743 and developed in C++ with CubeIDE, it compensates for drift with interpolation. A custom KiCad-designed PCB hosts this real-time audio processing solution.

Portable games console, designed from scratch: CPU, graphics, PCB, and the kitchen sink

inki is a compact, energy-efficient and battery-powered system for ePaper-based display of information gathered via Wi-Fi, as for instance room signage. It features RTC-based power control allowing for low power consumption, the project includes 3D-printed cases, and a custom PCB.
