Tiny PCB PiezoPiano Plays Just One Octave
Grand pianos are beautiful instruments, but take up altogether too much space. Upright pianos are smaller, but still fairly hefty. When it comes to the PiezoPiano, though, we suspect nobody could complain about its diminutive size. It’s a tiny thing with just one buzzy little octave for your playing pleasure.
The PiezoPiano is a single PCB device with a ATmega4809 running the show. It has eight buttons and eight piezo transducers that give you just one octave’s range on the keyboard. Truth be told, that’s only in one scale; you’re not getting the whole twelve tones of flats and sharps included. And, when we say keyboard, we really mean “tactile buttons.” You get the drift. It’s all assembled in a cute enclosure mimicking the shape of a real grand piano.
Fundamentally, it’s a cute little musical desktoy that reminds us greatly of the Stylophone. Impressively, though, those eight buzzers mean it has eight-note polyphony. That’s nothing to sniff at compared to all the monophonic synths out there. It’s also available on Tindie if you’d like to buy a kit off the shelf. Video after the break.
