thank you <3 my first mission is to get the hair off of my knuckles! It's very accessible for self work, it's good practice, it's very not affirming hair even after becoming a lot thinner and lighter, and because it's thinner and lighter, the kill time per hair is a good amount lower too! Probably one or two hours of work first pass do both hands! Once I've done that I think I'll have a good read on the board user experience wise for RC2 changes.

I deeply appreciate you stopping by for all of these! I reference your technical advice every time I start a new design and I'm gonna roll some of your more recent advice into the RC2 as well. Thanks for stopping in

the black soldermask was like $2 more but I think it was so worth it, I kinda made a snap desicion that this one was gonna photograph well and planned accordingly. and yes! building shit is so good! This is my biggest solo project ever and it has been making me feel very good, although for me especially but I think for everyone to a certain extent, solo work is super challenging. Do you have a local makerspace? I'm not working thru one right now but I dearly miss every time I've spent time building in one, or especially with people in one!

glad to hear you can confirm that professionally! I'm happy that it's a reasonable idea! It definitely takes the pressure of "okay this board isn't an alpha so nothing can be wrong" and instead I can just go backwards - nothing is wrong, so we can call it not an RC any more. I'm glad you're excited 🎉

NO YOU

hi I appreciate you stopping by! <3

I hope I can have something for you soon! I don't want to false advertise - laser can do a lot that this can't, particularly for diffuse dark body hair and minimal session time, and even if (when) I stick the landing and make something perfect, it'll be challenging to impossible for self use in a lot of the most important areas. It's ideal if you have another person to work on you or to work on each other together with - it takes things from time consuming and difficult to time consuming and rote but very achievable. I know a fair bit about different hair removal methods at this point though, so if you have questions, about my thing or in general, let me know!

thank you and also you're gonna make me cry

If you'd like to be on the tag list, or if you're on the tag list and would like to be removed, let me know here or in a DM!

done! and forgot to update you with such! but you have your new account in the tags!

cool! I'm excited that you're excited! I'd probably recommend waiting at least until the next alpha at this point, there are a ton of brand new changes in this and I'd hate to have you build something completely busted. I might be three weeks instead of two on the next post, but I'll try to remember to let you know if it's a complete dysfunctional mess as soon as I know. You're on the watch list now btdubs

I have design ideas, yeah! I'm decent at that, and having it all in Jekyll makes it so much better than having to write plain HTML. Thank you again for doing that! I haven't rolled it in yet but I'm going to try to get to it tonight!

just updated the post with schematics, renders, and board layout! Thanks for stopping in!

Version 8 is cool! I started the project in 7 and the upgrade didn't break anything, although it changed the whitespace formatting in text files so I had some crazy git commits. It also comes with some nice but fairly modest features. https://www.kicad.org/blog/2024/02/Version-8.0.0-Released/

Yeah wasted space is definitely a thing here lol, I just wanted to get something usable out the door. I'll re-pack everything for Alpha 2. Honestly this is pretty bad layout on my part, I focused on laying out each module well, and then at the board level I kinda just slapped things together. It would make JLCPCB kinda impossible, but I sorta love the idea of putting the battery holders on the bottom and using them as feet, and routing in the space on top of them. We'll see, but I'm really prioritizing JLCPCB orderability at some point, if not right now, for the accessibility, which kinda means everything on top. I'm also inbetween price tiers, I think: 100mm x 200mm is where I'm at now, and the next tier down is like 100mm x 100 mm, which I'll never hit. I'm barely over 100mm x 150mm, so I figured I might as well just use the space if it's free. But I totally will repack in the Alpha 2.

I am thinking of an optional enclosure, but that's for someone in the community to implement if they'd like to! It'd be a quality of life improvement, I'm worried about it getting shorted on stuff as a naked board, but this is also definitely not the final form factor, so nobody should start on that quite yet.

Mouser share cart is the plan for now!

added! thanks for being around! let me know if there's anything you're curious about and i'd be happy to talk about it!

this is definitely quite in there lmao

What tools did you use? I'm working with what I have, which at the moment is an allen key and a cotton swab with the ends cut off. Basically, I put the cotton swab stick down the lead chamber and I'm pushing it in with the allen key (the allen key on its own isn't long enough to reach the back, I added the cotton swab stick for more reach). So, that is to say, I'm now trying to push the collet out the front from the back. I'm not seeing a way to grab the collet, it's pretty deep in the tip of the pencil. Does this sound like I'm on the right track?

edit: just re-read your post, I missed that you said pushing it out from the back is a no-go too. oops. Did you have to do anything to the plastic body of the pencil? It looks pretty intact from your photos

edit 2: I got it I think trimming the end might actually be mandatory. It wasn't so bad, I did it with a swiss army knife. The result is pretty clean looking. I just trimmed back enough of the tip so that the shoulder of the wide part of the collet is all the way out when the end cap is pressed, and then from there it was easy to get under it with a pair of tweezers and pull. I bought a few of these, so I'll do one more and take good photos. It works beautifully and I'll let you know when I've used it for the first time!

hi welcome!

In extremely short, I'm a trans girl with the technical education and material resources to attempt to fix the problem of electrolysis hair removal being frustratingly hard to get. All of the existing ways of getting electrolysis hair removal are one or more of expensive, unsafe, or ineffective. This project, when it's done, will have none of the above problems by:

• costing less than $100 to purchase all parts and supplies for
• coming with extensive manuals and advice for effective operation
• being designed to the standard of a quality consumer electronic device and then some

Right now, I'm not done, but this is an important milestone. This is my first proof of concept that rolls the entire project into one single board - just build to the design, add batteries, buy peripherals (foot pedal, mechanical pencil for probe holder, and actual electrolysis probes) and go, provided you have electrical engineering knowledge. As I develop over the next month or two, I'll be removing parts to reduce cost, working out bugs, and making sure it's designed in a way that lets you order completely built circuit boards so it's solder-free for the end user - end-game is if you know how to install a 9V battery and turn knobs, you know enough about electricity to use the Sphynx.

Electrolysis is hard to DIY even if I execute perfectly, so some areas (hands, arms, face?) will be doable with self work, others (particularly bottom surgery prep) are best done with a gal pal.

Here's the primer post.

@YearOfTheCommieDesktop@hexbear.net - How did you get the collet out of the Yasutomo Artist Pencil 1.1mm? I'm genuinely amazed at how well it holds a probe and how easy it is to install one, but I can't figure out how to get the collet out of the body of the pencil for soldering a wire on to. What did you do there? I tried pushing it in the tip and out the back thru the lead cylinder but I'm scared I'm going to break something, I already put a decent amount of force into it
