I have some of these pots, not used them yet, how are you finding them?
I´ve not used them prior to the project I’m working on, so I really can’t say yet.
I bought 10 as a trial but not used them yet
It is alive! First midi data from the Stochastic-Melody-Make-O-Matic played by a Crave with some help from a Braids and some delay from Time-Warp-O-Matic for extra bounciness!
I haven’t finished the build yet, so I need to add more components to the PCB and write some additional code, but this is the first test. Initially I wrote the software for an arduino nano but given that that did not have enough IO-ports I switched to a BluePill. In platformio I only needed to choose another MCU and rename some of the ports and it compiled without a hitch. I had expected this to be much more work.

One of the 15 I have turned out to be broken. The trace for the LED shows a cut. So I ordered some spares.
Got a few modules wrapped up yesterday. Getting ready to fill up another kosmo case.
After these, I’ll give the super simple midi controller a go.

The VCADSR is fantastic. Changed my life.

A bit nervous posting here since you folks are all putting out some crazy good stuff, but gotta start somewhere, right? Being the new guy (to both this forum and audio electronics), I present to you my APC. My next steps are figuring out how to add a 1/4" jack that overrides the speaker when something is plugged in, replace that 9v cell with a micro-USB rechargeable option, get it on a protoboard and case it all in a little enclosure I have been saving for such a project.
If any other newbies like me want to try this out, this Instructable can be followed in an evening.
Meanwhile, I’ll keep working to get up to the forum’s level!

Congrats on making the leap and starting! If you haven’t seen Moritz Klein’s YouTube series, he’s got almost every circuit you’ve seen on the forum covered start to finish on a breadboard.

I’ve been working on the software of Stochastic-Melody-Make-O-Matic while adding hardware components to the PCB bit by bit. I found this makes it easy to test the bit of software that uses or depends on those parts of the hardware. It also makes it easier to find whether a problem is caused by the software or hardware. Most of the discrete IO (various status LEDs, clock input and output, tap tempo key, gate out, gate ins) is already working as planned. Next to work on are the analog IO functions like DAC and CV-in.

Another one-day build: @HAGIWO Sync LFO.
This one is as simple as it gets, just wiring MCU I/O, definitely a lot of value for such a simple BOM.

I built out a CV-8 awhile back… useful module

thats a cool face panel , is that one of your printed ones ? .
Yes, using my software as always. For now, the texturing is done in the slicer (it’s just a standard infill pattern) but I’d like to make it part of the system eventually.

I made myself an adapter Panel for the rings that I got recently. Having a small cnc is really nice at times!

Not finished by a long shot but I got a lot of work done these past few days.
I’ve been mainly working on the software side of the project. I worked on the classes for the rotary encoder, push buttons, potentiometers, sliders, the LEDs, the neopixel display, the gate inputs and output, the clock in and clock out. Furthermore, I also replaced a defective slider, ironed out some small omissions and errors in the PCB design. There is more work to be done, but the contraption is coming along nicely.
Note the make shift scale on the left top dial … just there to make testing the device a bit easier.

Here is my build of the Moritz Klein 40106 VCO. I just have to drill the panel and make it look pretty. I have a heap of 40106 IC’s so this is the type of module I have been looking for.

New case, for drums mostly, where I have mounted my dfam clone and just finished the big button module with midi. I had to tweak the code a bit (from Extralife youtube video).
