hello I have just removed my first body hair using this DIY hair electrolysis machine I built. The current is controlled by how hard you squeeze the pop can and the power source is a car battery. I intend to improve this but for a first attempt I cannot complain

@n3tcat a) this is incredible will you be publishing gur schematics / board / instructions somewhere??????? (i would love to not have to find a hair removal place, pay a bunch of money and then have someone else poke me)

b) how does gur pop can squeeze sensor work thatd be amazing for my next wierd game controller

@bx a) So I do open source all my projects so that'll be board + schematic (including bom) + code + 3D cad files for box and the actual pen thing. I probably won't publish instructions though - both because I don't enjoy writing instructions and because I'm a teeny bit wary of people using this device; I believe it to be pretty safe but it is obviously not certified in any capacity and could totally have problems that I've overlooked. I would be very sad if anyone got hurt

b) basically the resistance between your body and the can goes down the harder you squeeze. I'm not sure on the exact mechanism but it is pretty non-critical on the conductor
@n3tcat a) makes allot of sense!
b) ooohh, so you can use it as half a voltage divider to get an squeeze-controlled voltage you can use for an amplifier/mcu input???
@bx Yeah you probably could!
