This remake features upgraded electronics for the Led Panel - Panneau à Led (https://www.thingiverse.com/thing:2626217), designed by HelioxLab. A PCB board has replaced the strip board, incorporating a 10K slider to dim lamps using pulse width modulation. The PWM output is generated by a 555 timer driving a N-Channel MOSFET, with the slider controlling the mark-space ratio. A PWM frequency of around 1kHz is achieved. The DC-DC Buck Converter sits on the back of the board (https://www.ebay.com/itm/1PCS-DC-DC-LM2596-power-Supply-Buck-Converter-step-down-module-NEW-CA/142147326064?hash=item2118a41070:g:L1kAAOSwvzRXzOBg). I've used these converters before and encountered different hole spacings on various boards. Hopefully, you'll get the variant designed for this PCB. The SEPARATION.stl file was not included, so the board was hot glued in place after testing. Single 18650 3.7V Battery holders were attached to the back panel using hot glue. Everything fits together well. Thank you, HelioxLab, for a fantastic design. Great work!
