On Hackster.io, Jeremy Cook, writes about the Harmonicade, a modular 5.5 (x2) octave, multi-channel MIDI keyboard which uses arcade-style push-buttons arranged in the Wicki-Hayden button layout.
Like Dvorak layouts, this alternate note arrangement is much less common. As seen in the demo video, however, KOOP Instruments has leveraged the Wicki-Hayden setup to create a stunning dual-pad instrument that looks like a lot of fun to play. The dual input pads are entirely modular and plug into a central control unit using DB25 connectors that are wired to the buttons in a matrix.
The central board contains a Teensy 3.6, plus a number of additional buttons and knobs for control over the sound. After being properly translated, digital audio signals are passed along via a MIDI jack.
On the KOOP Instruments site, the have all of the CAD files, project code, and build instructions you need to create your own Harmonicade.
You know how in movies where there’s a mad genius tech-wizard/hacker (often a precocious teen) who can make the most fantastical creations with seemingly no effort?

The average US household replaces their mattress about every seven years. So if it’s been more than that, or even a lot more than that, it might be time to invest in a new slumber HQ. And most sleep experts will tell you the right mattress really should be looked at as an investment. Because […]
If there’s any knock on most smartwatches, up to and including the industry-leading Apple Watch, it’s probably that the bands aren’t…well, they aren’t usually the greatest. While Apple is certainly making strides in the watchband game, most models are just as black, boring and nondescript as you’d expect from a tech company. And where many […]
For all their obvious similarities, language learning apps will often each take unique approaches to teaching a foreign tongue. Or, in the case of many services, a whole bunch of foreign tongues. While some providers give you access to training across overwhelming menus of more than 150 different languages, the people behind the Busuu Language […]
