Michael Kohn has determined to offer an entire new that means to “candy music” by creating an edible MIDI keyboard. Whereas some may say “give me a break” to such an concept, to these of us who’re always inundated by potential builds, a sweet themed keyboard most likely sounds scrumptious.
Plus, Kohn’s setup doesn’t look notably tough to assemble, and thus would not be an enormous time dedication. The interface of the machine is constituted of eight white and 5 brown Package Kat bars, forming an alternating association of keys in a small keyboard setup. These choc-o-keys are located in cardboard cutout holders and organized in order that they every push down on a button to set off the right observe.
The pushbuttons are wired as much as an ATtiny2313, which sends a note-on MIDI command when depressed, then a note-off command when the button is launched. An M5Stack Unit MIDI performs the precise sound, although it may, in principle, be used with different digital devices too.
Heaps extra information could be present in Kohn’s writeup, and supply code is obtainable on GitHub. The quick video beneath outlines the construct and offers a demo of it enjoying a somewhat acquainted — and acceptable — tune. In fact, the confectionery configuration could possibly be utilized to any variety of candies, and when you wished a extra everlasting and/or much less messy keyboard, non-food supplies could possibly be used with the identical electronics.
