As of now, I’m close enough to feature completion to know nothing will change anymore with the electronic part. Not much changed since my original post about MIDIfying the monotron ; the only addition was to connect the 5v source of the teensy to the VCC pin of the monotron so the whole thing can be solely powered from a single USB power.
So, rather than having to deal with carrying a break-out-box, I wanted to make it a practical sandwiched unit that would be small and compact.
With that in mind, I made a second copy of the control board that would fit the size of the monotron board (once pulled out of the box) and assemble them using the battery connectors I didn’t need anymore.
The result is an extremely compact unit that only misses a nice faceplate. Here’s a couple of shots.
Size wise, next to another great synth
The two boards stacked on top of each other. You can see the teensy on the right side and the dac in the middle
