I'm revisiting some projects I asked questions about earlier...

Joe, I'd be curious to see your preflashing machine. Tonight, per your recommendation, I bought an S11 bulb and a socket. I had soup for lunch. How do you house this device? Drill a 3mm hole in the bottom of the soup can? If so, how do you enclose the top and make it light tight? I'm sure I could improvise something, but if you have a good way, I'd rather hear it first.

Also, the bulb I bought is clear, not frosted. Does that matter much? Should the light be more diffused?
