[sdiy] My new Moog 960 sequencer clone module project.. slowly but surely ..

[info synthcube.com]

Even with the units mess, the evolution of a family of similar-height parts that, together, make for reasonable panel pcbs for 5U pcb designs is very exciting. Pete Hartman did the 5U panel pcb for the Klee Sequencer in MOTM and it really simplifies the DIY construction, unless you’re hell bent on panel wiring.

Hang on…3/8” bushing, 1/2” nut, and…6mm shaft?!?

Honestly, the electronics world is such a mess with units.

Let me just put in a plug here for the new-style PCB-mount 16mm Alpha pots.  These have solder tabs which are 0.1" closer to the body than the older ones, and they have much beefier 3/8" shanks (the same as 1/4" jacks) and appear to be made out of a higher-quality metal.  I buy mine from Small Bear, and I have been very very happy with them -- here is the URL:

http://smallbear-electronics.mybigcommerce.com/alpha-single-gang-16mm-pc-mount-6-mm-shaft/

These pots are exactly the same height as the Taiway PCB-mount mini-toggle switches that I also buy from Small Bear; for example, the SPDT On-On ones here:

http://smallbear-electronics.mybigcommerce.com/spdt-on-on-pc-mount/

Small Bear also stocks (at my request) 1/4 switching PCB-mount Switchcraft jacks, but these are not the same height as the pots and switches, so they require a separate PCB at a different height:

With these and some layout art, you can make a very nice panel PCB with very little wiring.

[CAUTION: Non-UBC Email]
Like yourself and David I also wondered about a panel PCB, being thoroughly allergic to wiring. But sometimes finding parts that are both what you want *and* close enough to each other in height... can be difficult

Regardless, it is a really lovely build, as Jean-Pierre’s builds always seem to be, and I particularly like that much or all of the logic stuff has been wrapped up into firmware.

One thing I hated the most while refurbishing 960 was the wiring. There
are places where several wires, maybe 5 or 6 are soldered in 1cm2 area
with not a milimeter of spare wire to pull. I mean it's one of the
earliest examples of non-repairable thing so popular now in smartphone
industry. You could take it all apart like panel, all PCBs, and all the
controls alone would still hold together in grid, so many wires.
And it looks like you're going the same path, so... good luck.
As it was said already, maybe it's good time to consider making panel
PCB to avoid wiring hell, and move this 50-year old design slightly
ahead by merely 15 years.

Don't get me wrong, I like what you do, enjoy your pictures every time,
and I'm impressed by how you still make this thing while the rest of the
world seems to waste time on pointless wars.
