So, I've just nearly finished a pretty big project -- a Serge-format version of the Quadra + Expander, for a fellow wiggler. This will be part of a larger Serge-style build being coordinated by Loudest Warning. Here is what the Quadra part of the panel will look like:

Here are the boards I have laid out and made for this project. They are all 6" high x 5.9" wide. There is a Panel PCB, a Translator PCB, and a Quadra PCB. The Panel PCB has all panel components and logic circuitry for the Quadrature Mode switch, and Quadra PCB has all the circuitry for the Quadra, plus the CV circuitry from the Expander, and the Translator PCB goes inbetween and is where all the interconnections are made between the Panel board and the Quadra board. It also has all the Quadrature Mode and OR circuitry from the Expander. Laying out this monstrosity was like an exercise in 3-D Sudoku.

Here is now the boards stack up into a sandwich:

I'm waiting for the pots and banana jacks to arrive from Small Bear, and then I can send the whole mess off to Loudest Warning for final assembly. But first I have to thoroughly test it to make sure that all this shit actually works.
Just catching up. Nice to see those extra pics, Dave. Can't wait to get hold of that baby!

Looking back through the thread, next I'd like the Rubicon 2, Morgasmatron and scanning Polaris next to each other in a 3-inch-deep boat. :hihi:

Nicely done! Looking forward to seeing the complete synth.
It's fitting into a Buchla-esq modulation panel to accompany my LW Sing To Me panel, Charlie's Animoo-on-steroids synth.

Now back to your regular programming.

Looks like a fun party!

Personally I'd have left the Sloth controls and CV inputs off the panel, they're plenty loopy without them, and put a mini clock divider or counter in there instead. Not my panel tho :-)
Zap him again! ZAP THE SONOFABITCH AGAIN!

Interesting! Not having used them, I was going with other comments on them here. Apparently, nlc includes them on a lot of builds. Anyway, I'm going with clock dividers on my NEXT panel. :lol:
