The box for the protosynth is finally complete. See the previous posts for details. The paint is still not entirely finished and could use some final touch-up, but it’s good enough for now. First pics!
All the hardware is in there and, most importantly, it all seems to work. All knobs and buttons register, leds light, and although there is no real gui, you can tap on the mock buttons and they register. Headphone output works, but I’m not sure yet if the voltage levels are right or if it’s clipping. All the parts of the synth work just as before.
The picture is taken at such an angle that the display looks empty. No, it works just fine. The led segment displays will get covered later, I still have to find some nice red film to put on top of them.
All the internals are in place. In the cover: thumbstick, big buttons and the headphone amplifier on the left, with the main UI panel and the touch TFT screen with its SD card slot taking the rest of the space. On the bottom: the synth on the left has grown itself an opamp attachment and a couple of admittedly ugly connectors, the USB+MIDI interface in the middle, and power supply board and the power connector and switch on the right. Oops, I forgot to remove the jtag cables for the photo shoot.
