Homebrew PCBs

really got some carbon welding rod at the tool shop.
is 8mm dia, 22cm long, copper coated just as you sayd.
cost 1,2eur a piece.

bought 2 and 1 is already soaking in the etchant to get off the copper.

will let you know if i have any results, and of course ask further 
questions..

thanks
