This is a really nice UV light box for making PCBs. It supports double sided boards, has a built in timer, and a safety switch to turn off the unit when opened. Looks like a great alternative to expensive commercial versions.

I’m just toying around with this idea at the moment. If I start using photo exposure PCB type production, I’m probably going to need a light box. I have tried using spray on photo-sensitive resist and exposure to the sun. It was a complete failure. Presensitised boards, and a light box seem the way to go. I haven’t read much about this technique on the web, so I’m still a bit cautious.
