Etching PCBs with safe household chemicals
by Ben on Mar.03, 2011, under Misc
A HackADay reader by the name of Stephen stumbled across a very interesting way to etch PCBs at home using three chemicals chosen such that, as he says, “you can safely put each one in your mouth.” While we don’t etch our own PCBs (yet), we found this post very interesting and will definitely give it a try.
