Hey! I'm looking at doing some single sided
pcb's. From what I can tell, if
I want the pre-sensitized board to expose in a reasonable amount of time, I
am going to need to make a UV box to expose it with. I could apparently use
a regular fluorescent bulb but it will take 30-50 minutes to be ready for
developing.... And with cats, dogs and teenagers (and a friends 3 year old
many days) that is way too long to assume something is going to be left
without being bumped or knocked over :)
So, anyone have a good source for UV bulbs between 350 and 440 nm ? At a
reasonable price?
I imagine these would do the trick? They even have some fairly large UV Boxes.

D***! Where did I put that UV box I bought on eBay a couple years
ago for erasing EPROMs? That might work for 4x5 Cyanotypes and
Calotypes!
