I always wondered if a small LCD projector would be enough to expose a

and are surprisingly bright at small distance (of course they aren't worth
much for what they are solf for, displaying onto large walls:)
If that worked, it would be easy and fast (no scanning, just project your
gerbers)
Hi Przemek,
Great idea. So if you are looking for .1mm resolution, you might get
away with this if the board is no larger than 60x80 mm. Assuming 600x800
dots and perfect, (the word escapes me), dot to exposure transfer. For
through hole, dips, then the resolution does not have to be so tight.
Nest is to find out if the wavelength of the blue emitters is short
enough to get the job done.
Best, Dan.
