We build EDM power systems, IoT devices, and custom electronics. In-house PCB fab and assembly. Active in open source, available for client work. Run by Nico Schlüter from Austria.
Open source pulse generator and power system for CNC electrical discharge machining. Real-time spark gap control, designed for accessibility — build a working EDM with a 3D printer and basic electronics.
GitHub →Open source arc generator for EDM. Power supply design, electrode management, and process control for open hardware electrical discharge machining.
GitHub →Theory & experiments with the HCNR201 — we designed and tested an analog optoisolator circuit working up to 1MHz.
More on PhosLab →Gate drivers, DC-DC converters, discharge circuits, power supply design.
Schematic through layout. In-house single-sided fabrication and assembly.
ESP32, nRF, RP2040. Firmware, real-time control, connectivity.
Rapid iteration from concept through tested, working hardware.
Architecture review, component selection, technical guidance.
DFM review, vendor coordination, production bring-up.
If you have a power electronics, embedded, or hardware project and need help — whether that's a full design, a review, or just a conversation about approach — reach out directly.
