This Raspberry Pi Xylophone Can Play Itself – Review Geek


When you have an interest in each robotics and music, one thing fascinating is certain to return out of it. That’s precisely the case for YouTuber HalStar, who tinkered with Raspberry Pi and ended up constructing this exceptional (and gifted) self-playing xylophone.

HalStar, whose actual identify is Stéphane, initially got down to study extra about robotics and to realize some hands-on expertise with quite a lot of mechanical elements, together with one they’d by no means used earlier than: solenoids. Stéphane additionally needed to additional discover Raspberry Pi. And if the resultant product additionally mirrored their curiosity in music? All the higher.

So, Stéphane ended up making a self-playing xylophone that may play tons of MIDI information. And sure, the instrument is technically referred to as a glockenspiel as a result of the bars are product of metallic (whereas these of a xylophone are product of wooden), however Stéphane selected to name it a xylophone as extra folks acknowledge that instrument.

Stéphane restricted the design in two methods: by solely together with elements that might all be simply obtained from the native DIY retailer, and to solely use common modules wherever attainable. If you look intently, you gained’t see a large number of wires or a breadboard or a customized PCB.

In the introductory video above, the elements used are listed out. There’s a Raspberry Pi 0 WH, a 220V enter—5V/3.3V logic, 32 12V solenoids, a two-inch 54 coloration LCD display, three rotary/click on buttons, and an interactive debug console. It’s additionally able to studying 1000’s of MIDI information. Each of the three rotary knobs serve a distinct objective as nicely. One is for monitor choice, one other for tempo choice, and the third for mode choice.

The setup can play “softer” notes, or it may be set to strike the bars more durable for a brighter and extra percussive sound (similar to precise percussionists do). And as we will see, the xylophone breezes by way of quite a lot of classical tunes, online game songs, vacation melodies, and extra. Despite being restricted to only 32 bars (notes), it handles every music like a professional.

In this second video, dubbed the “Details” video, Stéphane goes into extra element concerning the {hardware} and the console. There, all the particular person elements are clearly labeled, and we will see exactly the place they sit together with every of the connections.

Want to create your individual symphony of autonomous glockenspiels (who wouldn’t), you may look by way of the undertaking shared on Stéphane’s GitHub web page.
