Purpose-built platform that brute-forces 40-position rotary combination locks with a stepper motor. Firmware (Arduino on AVR) methodically sweeps every triple-number combination and flashes status through an onboard LED. Custom PCB in KiCad couples an ATmega microcontroller, DRV8825 stepper driver, CH340C USB interface, and power regulation for a self-contained rig.

50 years ago I was already opening all combination locks by combining hearing and touch, I guess I'm not alone ! But congratulation for the idea and the work done as well.
