sorry @lilypad@hexbear.net for not replying to https://hexbear.net/comment/7400109. i've been burned out and writing out anything more than a couple of short sentences right now is out of reach.
your message is really helpful, though, and i'll re-read it when i'm a bit better and look for some textbooks as you suggested. thank you so much for all of that! i'd love to see your build of sophie's electrolysis machine and any progress updates on your own design if/when you feel comfortable sharing. maybe you'll inspire other people to try diy electrolysis too!
