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
Alright, designed and ordered something nicer. This is, in theory, a full electrolysis machine
@n3tcat is it odd that I found it more charming when it was clobbered together from random objects
@n3tcat story idea I'm not going to write: there's a secret circuit that building and powering will turn you into a girl
@flamingspork what if u did write it tho and what if it was about me

@n3tcat that PCB is very neat, and then I clicked the thread and saw the car battery and slightly screamed.

Still, very cool.

@n3tcat (seeing the car battery) oh, ur one of those tgirls they warned me about,,
@self no no im just a silly cat u can trust me :3

@n3tcat if this works I'll take 2  

Are you open sourcing the PCB design?

@beaumains I open source all my work! But I won't be selling anything; I cannot because I'm on a work visa

@n3tcat that's odd.

Oh well, I'm glad women are allowed to solder their own electronics now. Means I can build one myself without supervision from a responsible male.

@n3tcat i fear your power
@flamingspork im just a silly cat I love to meow
@flamingspork @n3tcat
me too. I think the flames etched into the side of the battery given an intimidation bonus too
@n3tcat Okay, uh, WTF and also I want
@november just you wait until I have some time to work on this properly this weekend. currently I am procrastinating on a presentation I'm supposed to be preparing for. I have crazy visions of what I want this to be. it's gonna be great
@n3tcat coolest thing i saw today, best of luck with this project
@n3tcat this is so cursed. I love everything about it.
@n3tcat do you use the can as an electrode in your hand? when I built a diy electrolysis device years and years ago I used a tens pad stuck to my jaw, from what I know the electrode has to be as close to the treated area as possible
@Critias yeah I was grabbing the can with my hand and removing the hair from the back of the same hand. Tbh I don't think the distance between the electrode and the needle should matter too much, so long as you have enough voltage to push the desired current. Of course, if your heart is part of the circuit, then you really need to trust your current limiting. An overcurrent event when the electrode and needle are close should be much safer
@jpm @s0 @gsuberland eeeeenjoy
@arichtman @s0 @gsuberland that’s a whoooooooole lotta fucken nope right there
@jpm @arichtman @gsuberland what? It’s 12VDC. Worst case is you drop something metal across the lugs, and people do that all the time in cisgender ways. This person is even monitoring it as they go.
I don’t think a squeeze system is necessarily the best idea but it’s ELV for a reason
@s0 @arichtman @gsuberland it’s the volts that jolts, it’s the mils that kills. I wouldn’t want to be sticking anything electrical into my skin without a LOT of safeties, at the very least a single-shot pulse duration limit.
@n3tcat can you release a schematic?
@sweet_as_candi For this version probably not; it's too janky for serious use. I was mainly just making sure I understood the mechanism and that I could handle inserting the needle and the pain (of which there was very little).

My next version will be much better and I'll be open sourcing it. of course I cannot promise it will be safe or anything; use at your own risk
@n3tcat I love this. NF-A9 is to get rid of the smell of burnt hair?
@fwaggle hehe, actually this doesn't burn the hair so there's no smell (:
@n3tcat craziest thing I've seen today. you're clearly insane. please do a tutorial
@breval this is the most flattering thing anyone has ever said to me
@n3tcat on my way to build this setup in my basement with random spare car parts

also - that's fucking amazing, 10/10 
@n3tcat it looks so dodgy, can i please come and try it? 
@houseofxyz nooo u gotta wait until the next version!
@n3tcat ok, i'll try not to think about it too much then 
@n3tcat pleeeeaaaasepleaseplease write a guide for how to build this somewhere 🥺
@schrottkatze no not until the next version!
@n3tcat "The current is controlled by how hard you squeeze the pop can" Incredible, peak mad science 

@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!
@n3tcat is the little needle in the green alligator-clip the business end of the machine?
