Light Box

My light box is made out of foam board and 2 pairs of 6 volt bulbs (wired so it runs on 12 volts). I found plans for making this on some ATM's site (I'll include the reference when I find it again). The actual light surface facing the scope would be better with "milk plastic" but I don't know where to find that, so I used clear plastic with a sheet of copy paper behind to to act as a diffuser.

The box is held together with hot glue and some tape. I don't remember the exact cost, but the whole thing must have been less than $10 to build.
