This beautiful build looks like it’s come from the bridge of a WW2 U-boat, but it’s actually a completely new build. It’s also a Eurorack module, albeit one that doesn’t make any sound. It’s a voltage-controlled character display, which means that when you plug it into your extensive modular synth setup and start playing the keyboard, different characters will light up when you play different notes. That’s it! A brilliant, beautiful adornment, and an exploration of computing history.
