Mostly 3D printed and laser cut Eurorack enclosures, but also some modules.
Testing out a new AC transformer on my own custom linear PSU for my rack (made up of 3 of our X84 cases). So far, so good! Linear regulators are much happier (cooler) with the new setup. Also moving some modules around.

Skiffy 442T with the new PSU mounted all nice. This is for my band-mate but is a good test for how well the PSU fits. Only issue is the caps had to get moved a little to clear the corner tabs. Otherwise I'm happy with it!

Mock up of what the Skiffy 442 would be like with the new linear PSU option. I still need to do some QC on checking for ripple and noise but the burn in test went well.

Here's the PSU powering an actual module (our WaveBoy of course)! I tested it with a full 8 too!

Looking at the next project after our PSU and was looking at a I/O solution using balun line drivers/receivers. Here's my first pass.
2HP Eurorack I/O panel for the front. 4HP panel (for cases like ours that have rear slots) for the line-level I/O.

The Skiffy 656 is now available!
It is a 2-row (6U) 56-HP (112HP total) face-up case, like our Skiffy 642 though it has enough width for up to two rear mounted 4HP modules!

Preview of the new routing stuff in 0.63! Envelope and LFO can be used to automate the wave frames and the audio output. The other WB is running the realtime delay setup as a send via a mult and Veils.

Also I know a lot of folks have been waiting patiently for this, but the Skiffy 656 design is nearly complete! Of note, it can support up to 2 4HP rear modules instead of one!

Playing around with dual WaveBoys. 1st is my DirtySaws in detune with an AD envelope in retro mode. Output is split for a pure dry output mixed with the 2nd WB, which is in delay mode. No filter.
Sounds cool but I was also testing an alt recording setup and that didn't quite work out.

I just wrote a blog post about a possible PSU that can be built as a kit to accompany our Eurorack cases for those that fancy a nice Sunday read.

Finally back to cranking out WaveBoys! Here's one I just finished soldering and testing and is ready for calibration! Thanks for all the patient folks who ordered one. Current batch is likely to get 0.61 firmware (the one with the new delay mode).

Oof some days. So my old power bus failed open and was passing -/+ 15V to my modules (!). None seemed particularly bothered but that was bad. I've had my own active bus design for a while and, well, finally got a chance to test it for real!
Here it is!
