I posted this little demo in the Build Progress thread, and it seemed to generate some interest, so might as well make a thread now, even if itās still a WIP. Iām working on Revision 2, which hopefully will be fit for distribution. Thereās time to take your feedback and correct mistakes you might notice, but I probably wonāt add any feature request.
Okay so take a lšk:
(Peertube mirror without ads that wonāt embed on the forum: First tests of my Arduino Nano + Mozzi experimentation board - Diode Zone)
Itās running one of @HAGIWOās DCOs!
The plan is to distribute Gerbers + BOM + CPL that JLCPCB can produce, it cost me 20 French bucks for 5 boards with all the SMD critters bolted on.
I have a LOT to say, but all of it is already on my WIP web page, so thereās no reason to copy-paste, go read it if interested and lemme know what you think! Thereās time to modify things before Rev 2.
(The site AND the page AND the board are all a big WIP! Iām working to soon have a site describing all my builds past and future)

Jean-Luc DeladriĆØre came up with this MozMo module a few years back.
I built one with an Arduino Nano, using Mr Sensoriumās HiFi mode filter.
I never got it to work very well, but maybe sharing some ideas here will inspire me again.
I2S DAC?
Reading GitHub - sensorium/Mozzi: sound synthesis library for Arduino, I wonder if the purple PCM5102 DAC I used for MiniDexed might work for Mozzi.
My platform should be able to share software as-is with the MozMo! Itās similar but we expose different kind of I/O.
As for the PCM5102, why add such a powerful DAC to the Duino? Its tiny CPU would struggle making use of it I think. From my perspective sound comes out from dual PWM in HIFI mode, and the MCP4725 is just to output precise DC.

I love the Cursed Footprint! The flexibility of combining the footprints of pots and jacks (and switches and bottoms?) is a fantastic idea. Iām working on an all-purpose control panel-slash-I/O board and Iām definitely going to try to work that technique in!
The Cursed Footprint was hell to Tetris around and looks intimidating, though.
Iām not sure how to best explain how it works in a way that wonāt intimidate peopleā¦ So far, this is the best I could come up with:

No, I totally understand it! You jump one set of pads to use it as a pot, the other for a jack. The tact switch breaks out to one of the pot jumper pads, and the row of holes below the footprint are breakouts for connecting wires to IO/control components that are panel mounted instead of PCB mounted. One pin is for pots, one for jacks, and they share a common ground pin. It makes total sense. Perhaps that means Iām a bit mad myself, but Iāve been in the headspace of thinking about exactly this sort of thing lately, so maybe that helped.
