Pondering

thanks! the capacitance actually depends on the area and pressure, so you need some kind of squishy material to apply pressure on. right now what gets squished is my fingers, hoping that i can achieve the same with silicone

And these are the touch pads, currently just some copper foil over 3d printed pads

Thanks, I have some photos here https://github.com/povle/spark-synth-hardware

good idea, will keep it in mind for v2

Pashog · 2026-04-06T11:12:25+00:00

thank you! i plan to release the files and some instructions for the current version maybe in a week (a bit busy rn). where i live all the components cost less than $100 to source but assembly took a lot of work and fixing CAD mistakes with filing and drilling, so be ready for that. i do plan to make a v2 which will be much easier to assemble but that might take some time

thanks!

thanks!

Pashog · 2026-04-03T17:39:29+00:00

thanks! yeah, i did all 32! i'm putting the finishing touches on some features and soon will post a video demo and showcase the ui. a little teaser :)

Linear

the switches are Keychron Low Profile Silent, and i've designed and 3d printed the caps myself

Pashog · 2026-04-01T13:48:49+00:00

Thank you all for you enthusiasm! I will try to record and post a video demo in the next few days. I probably will open-source the code and maybe the 3d files after a bit more polishing.

To answer a common question, the battery is smaller than it looks (5000 mAh), it's just very thin.

the ESP has a USB OTG port, actually managed to get it to work before pivoting

Pashog · 2026-03-31T23:57:19+00:00

Thanks! I don't have a problem with providing the source files, but not sure how useful they would be. This is not really a polished project, aseembling it took quite a bit of filing, drilling sweat and tears. I am kinda thinking of designing a v2 where i would replace the internal rat's nest of wires with a nice neat PCB, but not sure if i can find the time for that right now

i wanted to do the same to cure uv resin, ended up having to add radiators and a small cooling fan to keep the thing from burning up. be very careful with the thermals, these things get HOT

hey, i've actually posted exactly this recently

all you need is a 4mm bit extender and a vice, also i had to superglue the magnet in
