Electronics development and bench testing

I develop electronic applications, validated on an automated test bench, and I diagnose or repair the electronics of industrial machines.

Development of electronic applications on ESP32 and M5Stack, validated on an automated test bench: AI-driven tests, camera-based analysis, test report delivered to the client.
Embedded systems on ESP32 and M5Stack, programmed with PlatformIO.
Design of printed circuit boards (PCBs).
Diagnosis of servo motors and their drives.
Repair of industrial equipment, for example a laser cutter.
Reverse engineering of Nextion touch screens and of the serial protocol of a Haas handheld control.

Assembly of a series of electronic interfaces for an industrial client.

Servo motor encoder board, recalibrated with the trim potentiometers.

Differential pressure calibration instrument, from 0 to 200 Pa.
Portable vibration analyzer.
Laser guide for fabric cutting.
For a client, an ESP32-based controller with position sensors for a Fahringer saw blade welder from the 1980s or 1990s: it replaces a mechanical control whose cycle was not repeatable. Consistent welds, simpler operation and fewer operator errors; weld and temper modes, screen and settings menu, configuration through a web interface over Wi-Fi; monitored emergency stop, timers and automatic reboot in case of a lockup.
Diagnosis of servo motors (Inovance SV660N drives, Delta ECMA motors) and repair of a laser cutter, for a welding and metal fabrication shop.
Electrical work on welding positioners, a rolling machine and a plasma cutting robot, for a welding and metal fabrication shop.
For a welding and metal fabrication shop, zone-based protection on two plate rolling machines, machines that are difficult to safeguard: laser sensors stop the machine when an operator gets too close, and an indicator light shows the zone in green, yellow or red.
