LED Based UV Light Box

Whilst getting your PCB's made in China is pretty cheap and of a much higher quality than you can produce yourself, it's nice to be able to make your own for prototyping or small home projects. Added to the fact that making your own is quicker than waiting several weeks for a board to arrive from China, I wanted Harry to know how it's done just as I learned with my dad when I was his age.

The first thing I was going to need is a UV light box. Again, I could have bought one but where's the fun in that? I found a great example on insrutuctables.com of a UV Led based one, so decided to make on based on that design.

No point in going into detail about how to do it, heres the project on instructables: http://www.instructables.com/id/UV-LED-Exposure-Box/

We had an old case which had been lying around in the garage for years. It had some cheap kitchen knives in it which for some reason I bought many years and never used.

We bought some UV LED's from Ebay for about £8 (spec of these described on instructables.com)

We wired up all the LED's, resistors and links and tested it on the bench PSU.
