[sdiy] PCBs from printouts

JB,

better).

I have HIGH quality scans, 600DPI :-)

ooo, good idea!!!!

this is great!!!

Its very high quality, but I can neaten it up a little (I need to edit the
connectors anyway)

> Last but not least : you can re-use the film almost as many times as
> you want...

SUPERB!!!!

JB, you're a star!
