Need to make more like this!
I have a project in the works that combines four guitar pedals. This one is a dual LFO noise/rhythm generator.
I've updated my Forbidden Planet Krell Display to allow me to produce a 12HP EuroRack panel version.
Looking promising so far...
And so here are my design notes.
This is essentially my take on the Music From Outer Space power supply (links and references in the post) but with an added 5V line too and three connectors ready to go.

Now that is a surprise. The darn thing appears to be working.
No bangs or pops. And the voltage level looks pretty stable to me when powering my DIY module using +12V...
This is to go with my "cake box" mini-rack for testing things.
I'm writing up the design as I type, but won't be publishing the files/build for this one. No-one should be trusting me for a power supply :)
Finally got a patch running on this case. It's exactly as mind bending as it looks Next iteration will have a more considered system for braking/movement, which is the biggest challenge at the moment.
I'm quite pleased with how this has come out - it is a 3U/30HP EuroRack lid for a cheap supermarket cake box (that we just seem to collect - I use then lots for project storage!)
I need to fiddle with some tolerances, and not sure if I want to put screw holes in or not. I might leave it as "drill a hole when required" - it is really just for something easy for testing modules.
Once I think it is done I'll stick it online :)
Hainbach talks to Jan St.Werner of Mouse on Mars and Peter Blasser of Ciat-Lonbarde about their "very unusual synthesizer. Rather than creating lush textures, it is meant to excite and play acoustic spaces. Clicker compresses and expands a rich spectrum derived from "Ringlers", a new take on Rob Hordijks "Rungler". Originally made for an exhibition it is now a standalone instrument."

MIDI interface and prototyping board for an Arduino Nano.

This is something I've been working on for a few months now - only just making some serious progress during my week off. It's a #eurorack case. It spins.
Power and audio delivery are via slip-ring. Have yet to test the stability of CV in this way but I at least know that the audio is completely clean from early testing.
It all started with a misunderstanding.
I've put up the design and build notes for an Arduino Clock Generator Shield which shortly I'll show working with my Euclidean clock and drum trigger...

had to try out some video with the audio interface I hoped would work for quick shots on the new phone, and it does!
My new video on building an Eurorack envelope generator is out!

I also started a Patreon. Please consider joining in if you want to support my DIY synth projects. I hope I can get a more constant stream of output by doing this. I'm still going to publish everything publicly like schematics and design files but you get early access and I hope that there will be a vivid discussion, e.g. on the polysynth build. Any support is very much appreciated! Find it here: https://patreon.com/Polykit

getting going with the little synth/sequencer/groovebox thing I want to design. I want it to be like a beefed up pocket operator, with a little oled display (128x128), some encoders, and hopefully some "analogue" controls for extra modulation/expression - capacitive sensing maybe?
will be using an RP2040 given that they are Available. might even use two given how cheap they are. that would be four cores to play with.
synthesis wise there are lots of things I would like to cram in. all depends on CPU budget.
For anyone interested here's a peek into the innards of the delay unit.
It consists of a cheap common PT2399-based delay PCB off Aliexpress, a few extra pots, an Arduino Uno and a DIY MIDI interface for MIDI tempo sync.
