A cheap and simple UV exposure box for creating PCB's using the photoresist method. The current solution is huge and inconvenient.

The box will consist of a frame, a matrix of UV LEDs and a timer circuit. The solution will be geared towards 10x16cm copper clad boards, and will therefore have a small form factor. For the timer circuit I propose using one of my ATMEGA88's and an LCD module. The box will be powered by 12V and by putting LEDs in series (every 2 or 3 LEDs, depending on Vacross) I hope to keep wattage down.


500 UV LEDs are currently on a boat from China towards the space. This should be enough for at least 1 decent size box and a tanning bed.
