so i did it i finally did it i finished the whole design and i got boards made and i ordered them from JLCPCB and they’re coming in two weeks and it’s gonna work and it’s so good and we’re so back goose-default-dance

sorry for the break, life comes at u fast, but i am coming to u with progress! i don’t necessarily endorse this version as i have not tested all of it, however all of the additions are relatively mild (1M bleed resistor on the output, that’s pretty much it) and the rest is some pretty aggressive cuts to get it across the finish line (remove the optional current sink because it didn’t look like it was gonna pan out, remove optional current limiting diode because it’s impossible to source and kinda not necessary, remove the feedback inamp because it was inconsistent and potentially causing issues and anyone who needs to know the output current can just use more advanced tools to measure it, remove voltage configuration entirely and hard set it at 16 V because current is mostly the only number that matters anyways). these removals allowed me to fit it into a 100 mm x 100 mm square which will save costs. this definitely isn’t a sure fire build of things but it’s not bad odds that things work on the first try!

board is updated on https://git.sr.ht/~_410bdf/sphynx, exports for JLCPCB live in https://git.sr.ht/~_410bdf/sphynx/tree/main/item/Electronics/Boards/Lite/Lite%20Alpha%201/jlcpcb, this is theoretically orderable but maybe hold off until i make sure it works. while i wait for it to arrive i’ll be working on materials for putting together the peripherals like the probe and the pedal and getting the site up to date.

this is a haphazard and short update but i’m back and i have made a significant amount of progress since we last spoke and things are looking good <3

will share more later! let’s chat in the comments! love you all! bye!! trans-heart

    hi!! yeah! there are a few other tools necessary that i have enumerated back on one of my older posts, maybe 5 or 6? basically you need:

    housing is not necessary but i am very excited to see what the community is able to come up with for prints and things!

    i’m also going to aggregate materials in the coming couple weeks, both for materials that already exist on performing electrolysis generally, and write-ups that i will make myself for the sphynx board in specific. i have https://sphynx.diy/ up and running to host guides and materials and anything else i need to put up!

      Ok cool. After you’ve tested can we get all of this in one post and perhaps a really simple step by step guide to sticking the parts together? This is probably something most people can work out from the bits and pieces but to really make it something viable for everyone the step by step handhold guide will be essential.

      After that pushing it around different media spaces is all that’s necessary so more people know it exists. Having its own dedicated project space for people to discuss it would probably help with people who have unusual questions.

      the following mechanical pencil: https://www.jerrysartarama.com/yasutomo-artist-mechanical-pencil-1-1-mm-black (thank you @YearOfTheCommieDesktop2@hexbear.net assuming you’re still here!)

      I am blocked by this site. Might need to source a version that’s available to Europeans. Is it this one? https://www.saveofferfy.com/product-p-841349.html

      What I picture is something like 4 different sections:

      1. Parts you need (suggested parts and sources for getting them, also suggested sources for pcb printing)
      2. Construction step by step guide
      3. FAQ
      4. Forum for project discussion
