A ruggedized, 6-layer High-Density Interconnect (HDI) carrier board designed to commercialize Raspberry Pi CM4 prototypes into deployable industrial AI products. Engineered specifically for high-vibration, noisy environments (agricultural robotics, factory automation) featuring automotive-grade power protection and high-speed PCIe integration.
An affordable underwater camera built with an ESP32-CAM module that attaches to a fishing line. It features a custom PCB for power management, a waterproof PVC housing, and automatically starts recording when submerged. Designed for shore anglers who want to scout fish locations without expensive sonar equipment.

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.
Open source digital servo replacement module for the Sony Walkman WM-D6C. Replaces the CX20084 servo IC, CP304 boost converter, and CN301 power jack with a single STM32G0B1-based PCB. Dual variant: USB-C PD or polarity-agnostic barrel jack input. Bare-metal C firmware. CERN OHL-P v2 / MIT / CC BY 4.0.
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.
