AW: pcb's

My few cents ( ... Pfennige, actually):

I think the worst thing of DIY pcbs is drilling all these holes! So I don't 
think
heat transfer foils help you save much time.
I use the good old photo method. A photo-sensitive euro format pcb costs
around 2 Dollars, a xerocopy on a good foil another Dollar, chemicals
for one PCB are well below one Dollar.
Things I had to invest in (once in a lifetime): An exposure frame with UV
flourescent lamps: 200 Dollars (stay away from these cheap UV lamps,
they always die of overheating!) and an etching machine that blows air
thru your etching liquid: 100 Dollars.
With these devices, I completely etched a set of 10 eurocards for my
vocoder in a single evening. But as I said, *drilling* thousands of holes
takes much much longer.
BTW, I prefer the cheapest pcb material available - its far easier to drill
this than the expensive epoxy material.
