Some kind of polyphonic modular.

Sweet! Would love to hear some sounds from it! What did you end up using for your MIDI/Cv interface? Or does that KB just have mult CVs?

I am using the Mutable Instruments Yarns module for midi-to-cv. I've been building so much I haven't really had time to play the thing much yet. I'll share something when I get the chance, it's pretty cool.

I've cloned the Befaco attenuvertor;


Vert, I like how it turned out, finger space between knobs and cables at the bottom was a starting point, same knob height was a happy accident.

Nice! Is that a two color pin header or are the two "red stripe" pins simply a separate part?

[EdwinSL]

Yes, just a red 2 pin header, I actually forgot to add it in the silkscreen.

Really like that befaco attenuator redesign. I always thought the jack placement on the original was what was holding it back from being my favourite attenuverter design.

I built a Mutable Shruthi XT with a Polivoks VCF, and liked the sound so much that I wanted to build a eurorack Polivoks VCF module.

I only spotted that Erica Synths released their gerber files a few days after submitting this for fab. Oops. Well, at least it matches most of my other VCF modules a bit more, this way!

[gadgadasvara]

one of the great sounding DIY filter IMO.

MFOS Quad Timbre Bank
not yet on a faceplate....

Ok, this one is weird and sort of ancient, but I finally finished it, so there.

This is version 1 of the very first run of these. I built most of this when I got it, maybe 6 years ago - it was right around the time the TTSH came out originally. But I didn't have a case for it. So it sat, mostly untouched, on a shelf since then. I moved since then, rebuilt my studio in the new house, put it on the same shelf it had been. A few years ago synthcube started a pre-order for the cases for these, so I bought into it, and finally got the case a few months ago. Some more sitting around ensued, with a few brief spurts of activity, but today everything seemed to fall into place to actually get everything together, and now it is! Still have to calibrate it - hopefully I won't wait another 4 months to do that.

Started my first DIY project during the beginning of the pandemic. I've been on a bit of a Buchla tear lately. Successfully built a 266, 281 and 292. I'm wrapping up a 227, and three 258s as well. Photos are a little disjointed, sorry.

cool assembly mat!

Hi,
I continue my series of modules for less than 20 € and I've just finished a Quad Delay module for trigs & gates.
It's a "real" delay, i.e. it stores a serie of trigger events and restore them later.
Here's the panel :

And the video :

Those prices listed in the BOM are spectacularly cheap. I suppose you've got all the parts from CN.

yes... and by lots

Ha thanks I got it off amazon for like $15 or so. It helps keep things a little tidier though I feel like I could use a slightly bigger one.

[Stoneyards]

I built a 12u case this summer..

I wanted something to match my desk..

Working backwards, here's the finished product with genus modu bus boards and acopian power supplies. There's a powder-coated mesh back that goes on after this.

Birch ply and pulplogic rails before stain and wipe on poly.

Cardboard prototype helped me get the angles right.

..And yesterday I replaced the linear supply with switch mode supplies. Lighter and eliminates a bit of mechanical noise.

Finished up a Barton Chordizer today...

Some of my pluses came out a little negative from the laser cutter but lots of positive vibes today to make up for it as the whole town was out celebrating the homegirl KH.

As always: cool design.

[Dr. Sketch-n-Etch]

Wow, lots of beautiful new DIY on this page today. I gotta get busy.

[Peake]

Finishing a modified Roman 212. I'll post documentation of the mods later. Panel by Beast UK, thank you!

Finally finished some Oakley euro modules: viewtopic.php?f=36&t=240130!

[autodafe]

Finally managed to find some time to solder Jasper MIDI interface and to host it into the mahogany case I started building last July.
Here's the result, not 100% perfect maybe but I am quite happy on how it turned out, those recessed MIDI connectors in particular ;-)

I've been trying to learn pcb layout. I've yet to make one without a mistake but so far have managed to get everything to work. It's been fun. I've also been digging this laser cut aluminum from ponoko. Here's a couple of serge things in frac...

^ Dayum. Looking really clean as usual. Your builds are always a highlight on here. How much did the panels come out to?
