Brass Plaque Honors Brother
I have etched circuit boards a few times, and it's arduous unless you are set up for it. The chemicals are nasty, and flushing the waste down the drain isn't great. Electrolysis doesn't require nasty chemicals, and this project used salt water but was contaminated with copper afterward. The agitation method was clever because she used an aquarium bubbler.
