PCB UV Exposure Unit

A UV exposure box is an extremely useful piece to make PCBs.

I have searched and found that they are too big and too expensive for my uses. In addition, all the devices require an external power sorce.

Thereupon I decided to build one that fits better on my needs.

My requirements:
-Compact dimensions
-USB charging
-Long battery runtime
-No buttons or knobs
-Very simple use

So I built a box, with which you can exposure up to 184 PCBs on a single charge!
