    hello! I’d love to talk through it, but the very short answer is that this is fully global as designed. It runs on 2 9V batteries and is never connected to the wall at any point. Batteries are consumable and it’s a little bit of a bummer (these exist which mitigates this issue!) but there is a safety risk with having any direct electric line from the wall to a person. I trust my engineering skills but even if I feel like I could make it safely, it’s not worth the risk. If my circuit completely fails and the batteries shoot straight through to the recipient’s body, it’s just 18 V and it’s a little ouchie but no big deal, unlike with wall current, which is a very, very big deal. I would never endanger trans. <3

    hi! Perfect timing, I just sat down to conclusively definitively follow your instructions to get this patch implemented and then set up CD onto https://sphynx.diy. I’m honestly not opposed to you having push access to a branch, but I just have to get settled into the repo first and reacquaint myself how Jekyll projects are typically organized. I’ll let you know when I’m up to speed with where you’re at and then there’s a good quantity of site things to be done 🥰

    edit: holy shit patching with eml files is easy I don’t know why I was dreading this so much. 4 minutes. The CD job failed, I didn’t really expect it to pass on the first try, but I’m going to go into debugging that now

    edit 2: i fixed the build script chicken-bop I went down a somewhat (entirely) unnecessary rabbit hole of getting bundler installed as a user gem instead of as a system gem for the problem to be totally unrelated and just be system binaries anyways. Might change it back, might not. The important thing is that pushing jekyll automatically uploads HTML to the site. I can finally start writing blog posts and guides and stuff. Thank you :meow-hug:

    I’m very uncomfy around patch files in general, I’ve never worked with this development workflow before, so I’m just going to take a bit of time to get up to speed!

    first things first - the repo and the site are actually not connected right now, the site is just some raw HTML I wrote and the repo is blank, iirc? So I couldn’t tell if you were patching from the repo or the site. I found the official guide at https://git-send-email.io/, but that appears to be more for sending patches than accepting them, so it wasn’t super helpful to me. I just downloaded the contents of your email and tried to use patch directly on the contents in my working directory, but it looked like it threw some errors and I got scared off. Do you have some time to work with me on it tonight? I think I’ll make a matrix account so we can talk about it, if you have one yourself and like that method of communication!

    Your experience is super valuable here, I’m so happy someone who’s actually used the One Touch units has stopped in! Given they’re the only somewhat viable solution I know of for at home electrolysis, I would love to have you around for asking questions to!

    Ergonomics wise, you have some really good points, I like the idea of a audio beep when each hair is done and I hadn’t thought of it yet so I’ll try to roll that in somehow! I’m definitely aiming for hard to use incorrectly/easy to use correctly. Screens, even 7-segments, require an additional layer of circuit complexity that I might not implement in a 1.0 design, but it’s a possibility! I’m much more likely to just use status lights for now.

    I’ve heard this experience a lot, where using the One Touch leads to almost complete regrowth. I suspect that the One Touch uses an unboosted 9V, which is on the very low side - I plan to be able to drive up to around 22 volts, which I believe is the main factor of why the One Touch was largely ineffective. At that low of a voltage, from my understanding of units of lye, and especially if the probe isn’t sourcing very much current because of the circuit design or if your skin is highly resistive, it’d take over fifteen seconds per hair to have a high likelihood of killing the hair. I’ve also heard a lot about the One Touch needle probe being too thick to reach the depth of the hair bulb without pain and potential for scarring, further reducing the odds of successfully killing the hair - that’s the advantage of designing around the Ballet needles I have linked in the post, but they’re more expensive so there’s a flipside as well.

    by the way, do you want me to add you to the tag list? As I get more development done I’ll probably have lots more ergonomics questions and I’d love to tag you for them!
