A classic one-man band generally features a stringed instrument or two, a harmonica in a hands-free holder, and some kind of percussion, usually a bass drum worn like a backpack and maybe some cymbals between the knees. The musician might also knock or tap the sound-boards of stringed instruments percussively with their strumming hand, which is something classical and flamenco guitarists can pull off with surprising range.
The musician usually has to manipulate each instrument manually. When it comes to percussion, [JimRD] has another idea: keep the beat by pounding the soundboard with a solenoid. He built a simple Arduino-driven MOSFET circuit to deliver knocks of variable BPM to the sound-board of a ukulele. A 10kΩ pot controls the meter and beat frequency, and the sound is picked up by a mic on the bridge. So far, it does 3/4 and 4/4 time, but [JimRD] has made the code freely available for expansion. Somebody make it do 5/4, because we’d love to hear [JimRD] play “Take Five“.
He didn’t do this to his good uke, mind you—it’s an old beater that he didn’t mind drilling and gluing. We were a bit skeptical at first, but the resonance sweetens the electromechanical knock of the solenoid slug. That, and [JimRD] has some pretty good chops. Ax your way past the break to give it a listen.
Got a cheap ukulele but don’t know how to play it? If you make flames shoot out from the headstock, that won’t matter as much. No ukes? Just print one.

Arduino Percussion Car
amarok, arduino, filika, gallery, interface, istanbul, music, percussion Comments Off on Arduino Percussion Car
The user [selcukartut] sent us a project full integrated with Arduino boards. Filika (Istanbul) designed and produced an Interactive Percussion Playing Car for Volkswagen’s breathtaking pickup Amarok. Several sensors were implemented on the board, so that the participants were able to trigger percussion sounds via tapping their hands on the car.
Technically speaking, there were two types of sensors to gather user interaction data. Force Resistive Sensors were placed on the front panel and piezzo sensors were placed on the sides of the car’s body. Received user interaction was mapped onto a code via customized Arduino Board. Arduino code was commuicating with a sound patch that was built in MaxMSP/Jitter, and finally delivered into Ableton Live as Midi Data. In sum when a person taps onto a sensor that hides under the car’s surface, that interaction was turning into a percussion sound. There were tons of cables, sawing, soldering, coding and etc…
On the [website] there are some videos that show the project in action. Unfortunately all the text are in Turkish, we hope for an English, more international, version.
