That’s good to hear.
Yes, I’m a big fan of AMASS connectors. These are actually the XT30s.
I did wonder if the gel pad might increase resistance or trap hydrochloric acid under it. I had it on the top of my sternum when doing my face and didn’t notice any skin reaction under it (tried it on my cheek for a bit but immediately got a bit of tingling). I did try a bit of stainless tube without a sponge but when dry it actually had much higher resistance than the pad. I might see if I can make a solid stainless electrode with a banana plug socket drilled into it sometime that I can use with a sponge.
This circuit was mostly just made as a proof of concept to try out electrolysis, but I’m really happy with how it works (and much faster than I expected) so if I make a better one I’ll find a nice case for it.
