Can anybody suggest a cheap and effective method for fabricating PCBs. I've heard of UV as well as chemical etching.[/u][/quote][/list][/list]

I usually print the layout on my inkjet printer and then go to the local library and use their copy machine (toner) to copy to a sheet of photo paper. Then I cut the board to size, clean with laquer thinner and iron the layout to the board.

What do you mean toner? Laser Copy? Then use a regular photo paper? If yes, I'll try this one..... Presensetized boards are quite expensive.

As to the use of battery acid, you will need an oxidising agent as well.
When I was out of the appropriate echant once I tried a mixture of battery acid and chlorate weedkiller, the sort that idiots make bombs out of. It etched the board in 30 seconds, boiled over and ate the bench, and the fumes rusted every bit of metal in the shack. Be warned!
