We nearly don’t have phrases for this Raspberry Pi challenge as we’ve by no means fairly seen something prefer it. Nonetheless, right here we’re, and we’re past excited to share this creation from a maker often called JupyterJeff on Reddit (or HighQualityFun over at YouTube). Utilizing our favourite SBC, the Raspberry Pi, he’s created a musical robotic that may be pushed round utilizing a stroller.
It’s arduous to keep away from consideration with a creation like this in tow. JupyterJeff explains that it was supposed primarily to take to festivals, parades, and maker festivals the place folks anticipate this form of creation. That stated, it could actually flip heads if let free down a preferred alley or road nook. The Pi controls a collection of percussion devices and runs a synth to again up the beat with some candy melodies.
Songs have to be preprogrammed to carry out so he can construct up a collection of tunes to rotate by. So, along with the music you hear within the demo video, you too can discover it replicating Michael Jackon’s Thriller lately at Maker Faire.
A lot of the mechanical items had been fabricated utilizing laser-cut plywood. The drumsticks are designed to pivot on bolts. The laser-cut parts are operated by way of servo motors, and a few springs give the sticks sufficient drive to make a powerful sound when hitting the drums. A Raspberry Pi 4 is used alongside a Pi DAC+ to enhance the audio high quality.
The Pi operates the music utilizing MIDI/Karaoke recordsdata with the help of Rosegarden DAW. A customized Python script reads the MIDI file because it performs and sends directions to a Polulu server to set off the drum motors to hit the proper beat.
Total, that is one groovy Raspberry Pi challenge, and we’re simply jealous that we haven’t had the chance to test it out in individual. If you wish to get a better have a look at this spectacular Raspberry Pi musical robotic, go to the unique challenge thread shared on Reddit and watch the demo movies to listen to it in motion.
