I'm thinking about making a photo-plotter attachment for my router /
mill.
Do any of you know of a small UV light source that would be suitable?
I've found some violet LEDs, but I'm not sure they emit enough in the
UV range.

I'll probably include a small stepper and aperture wheel, which I'll set
up as the A axis in TurboCNC. I could set it up so that A1 would
turn the wheel to aperture 1, A2 would turn to aperture 2, etc.

I suppose if it's an incandescent / fluorescent source, I'll also need
some sort of
shutter affair too. I could probably spin the aperture wheel around to
a closed
position.

Any help greatly appreciated!

JJ
