PCB UV LED Array Timer

That’s a kind of project that took a long time to be finished, despite its simplicity! That’s because I have used, for a long time, a UV fluorescent lamp box to do my printed circuit boards and I always thought that another one, using UV LED’s, could wait once more time to be assembled!… Until now!The main design consists of a wood-covered MDF box, a UV LED matrix board and a PIC microcontroller to control exposure time. All the projecs is described and available below.

Supplies:
Laser-cut MDF parts;
light imbuia sheet;

UV LED array;
PIC microcontroller timer circuit.”
