[Jan Ostman] has been pushing the limits of noise synthesis on the lowly AVR ATMega microcontrollers, as well as his latest two job is so adorable that we just had to compose it up. The miniTS shares the exact same fundamental sound-generation firmware with his previous TinyTS, which we’ve covered right here before, however adds a great deal more keys, an OLED, as well as MIDI, while taking away a few of the knobs.
Both function keyboards that are just copper pads put over a ground plane, as well as the code does simple capacitive-sensing to figure out if they’re being touched or not. The point right here is that you might pick up a PCB from [Jan] on the cheap, as well as experiment around with the code. Or you might just take the code as well as make a less fine-tuned version for yourself with a cheapo Arduino as well as some copper plates.
Either way, we like the combination of very little materials as well as maximum tweakability, as well as believe it’s great that [Jan] shares the code, if not likewise the PCB designs. anyone with PCB design method might get a clone worked up in an afternoon, although it’s going to be cheaper to get these made in bulk, as well as you’re most likely much better off just buying one from [Jan].
