Homebrew PCBs

Hi all,

Do I see another wheel being reinvented here?

A UV laser works on photo resist.  Someone has already done this with 
a flatbed plotter and a UV Laser from a CD player I think??

Photo resist coated board is ubiquitous and (relatively) cheap 
compared to finding some other resist which could be lasered away 
cleanly.

What am I missing ;-)

Philip.
