Code-generated, machine-validated KiCad design for a 230 VAC to 5 V / 500 mA isolated flyback PSU (VIPer06HN + Myrra 74001): schematic, PCB, DRC rules and BOM emitted from one Python file, checked for 6 mm mains isolation without opening KiCad.

SOIC8-DIP8 footplint adapter PCB

NebulaTune is a HF reciever with a direct conversion single balanced diode product detector and a Si5351 as a local VFO. The VFO, encoder and the display are all controlled by the RP2350. I will get parts soon and start documenting the build process. Website soon

unipolar dummy load testing utility

A custom 4-layer ESP32-C3-WROOM-02 development board designed in KiCad 10 - includes USB-C power/data, schematics, PCB layout, and manufacturing files.

A wire-free laser security tripwire system powered by an ESP32-S3. Features independent transmitter nodes, multi-bounce mirror pathing, dynamic auto-ambient light calibration, custom KiCad PCB files, and 3D mechanical mounts.

Manufacturing-ready Li-Ion Battery Protection PCB designed using KiCad 9 with complete documentation, Gerber files, simulations, and manufacturing package.

Custom STM32F103C8T6 development board

2.4 GHz MIFA trace antenna design and simulation. Modeled using Ansys HFSS with Optimetrics sweeps to optimize geometry. Implemented on a custom 2-layer KiCad PCB using a coplanar waveguide. Includes LiteVNA verification diagnostics and a calculated Pi impedance matching network.

The 24-signal interface board that replaces SHADOW's perfboard wiring — and the two pin conflicts that only appeared on re-checking the spec.
