People who are going to #emf2026 and enjoy making #hexpansion and/or synths - I seem to be coordinating a collective effort to make a #eurorack compatible modular synth in #hexpansion form. If that sounds like the kind of thing you might enjoy being part of, please let me know.

@jarkman@chaos.social super interested, very limited electronics design experience but a lot of enthusiasm?

@jarkman@chaos.social I knew I should have put a 3.5mm jack on the DECTalk hexpansion!

@jarkman@chaos.social I did take a quick look at the hexpansion spec, to see if a DAC + headphone out would be easy enough to cobble together for a Kicad beginner referring to MI schematics, but gave up after seeing just 3.3v. I've already got enough to do before EMF, soldering 5 modules (2 SMD) and building a 4Ux62hp case out of Penn-Elcom extrusions, as an upgrade from the one the Workshop System comes in. --- o/ @Gogledd@meow.social fancy seeing a fellow Wiggle Roomer on fedi ;)

@jarkman@chaos.social I was guilty of using the '22 badge to perpetrate Euclidean rhythms, sent to a couple of Bastl Kastles via some breadboard 3.5mm sockets in a vacant NullSector container. I did wonder about I2C DACs for CV-out on the current badge, with suitable passive RC filters to smooth out the dots. (Did that with some Bela boards...) Also keep wanting ulab in micropython on the badge for making noises: https://micropython-ulab.readthedocs.io/en/latest/
