The mixers I make are just Sam’s simple ones. Tl074 bunch of 100k Res and 100k pots for the most part.

I was waiting to order sam’s mixer until the O.B.A. came back in stock. Jokes on me!
What I was meaning was a description of how many mix busses and/or how many ins and outs. From looking at it ,it appears to have more than 1 output.
Same. I decided after the first five or six modules not to worry about “symmetry” and measurements when plotting my components on the panels. 
Not to mention my labeling in all sharpie markers. I just wanted to get it done. Your wiring is tidy and the panels are polished. Looks fantastic even with the sharpie labeling.

Do u mean the one from Sam’s shop (6 to 1)? The befaco (black red, 4 to 1 with inverted out) or the DIY ones (4 to 1)?
Nice Work Dude.
Is the bottom right section a 16 step sequencer?

Thank you! Yes it is a 16 step sequencer.

Build of the MS-420 Filter I posted the Layout for. (Verified Stripboard Layouts! - #624 by Softek)
I currently enjoy taking a break from building modules and building small battery-powered boxes instead

I like the folded sheet metal box - care to walk us through the construction process?
The enclosure is bought I’m afraid 
The manufacturer is Teko from Italy

Good to know - maybe cheaper than Hammond enclosures…

Certainly! This one was 4,99€ at reichelt.de. Still a bit on the pricy side in my opinion, which is why my next builds will go into plastic enclosures, that cost me around 2€ for a similar size.

Small battery powered boxes are wonderful

Been procrastinating/having a really hard time commiting to which modules I wanna build after getting my feet wet and changing directions, but I tried to spend that time coming up with an enclosure, 'cause as much as I want to like scrappy DIY, I have a hard time working without standards for sizing and such.
Got my DIY/choice paralysis panels from JLPCB today, so I have to put out a parts order tonight. (Someone tell me there’s no better analog clock divider for odd divisions than the Ken Stone, I really thought that concept would have a lot of solutions kicking around but it looks like his or YuSynth.)

I’ve added another euro-pi to my rack. They tend to come in multiples …
Probably I’ve said this before, but I’m especially fond of the CVecorder which allows you to record and loop/replay 6 CV signals and store them in 6 banks. You can then change from bank to bank and play ‘scenes’. You can see an example here:

LOL yeah it all seems to multiply . those units seem to be very handy I can see why you would want multiples . reminds me of my ornament and crime modules , wish I had a few more of those .

I like to throw a couple of simple builds in with any larger projects; so build a module and also a mixer or adaptor. If I didn’t, many simple must-haves like y-cables or making up a loop in the patch bay would be the simple job holding me back. So overbuild, underpower, cram those cases, smoke those chips and let’s have no more of this coulda shoulda. I never thought it’d be you Scott; passing up on all those additional builds for empty space and unfulfilled cases.
Saddened, I guess the rest of us will have to pick up the slack.
So to your benches mes amis and remember; volume, frequency and quantity beat size.

Some people seem to use a few and choose specific fixed scripts on each one of them. The modules then resemble a normalised setup of simple single function modules that are used as a basis for a patch again and again. Given that the euro-pi is very cheap to build, this is a very viable approach.
Also being able to program it in python makes it very easy to come up with a script of your own without the need of extensive experience in software engineering. If someone designs a KOSMO size face plate which interfaces to the existing backplane PCB, then euro-pi could easily be available for KOSMO without doing much engineering effort.

I’m mid deep dive and hardly skill worn when it comes to Python, the Pico audio design on such but I’m excited by just how much more is possible with euro-pi and a multiple of them?
Much like a voice, a single panel could host multiple picos, networked functions, discrete MIDI, shared or simple two pico for left and right.
I’m looking forward to seeing how this develops.
