Homebrew PCBs

Hi Rick,

I must admit that I have put DLP on the side for now because I have 
been unable to get consistent results. I bought a LJ2200 as someone 
else mentioned a while ago and had no problem modifying it to pass 
quite thick boards through, but the printing was not dependably 
uniform. Perhaps I'll get back to it another day.

When I have some time, I think I want to try using a laser to strip 
paint (resist) off the pcb. The technology is clear cut and certainly 
works. I found someone who can sell me a laser that will focus down 
to 3 mils (IIRC), and I have a pcb cnc mill to carry it. Someone in 
Instructibles described a using two flatbed scanner carcasses to make 
a paper cutting cnc laser for <$50 that looks like it would work well 
for this application, too.
