Berlin-based hackers create musical umbrella

During this year’s Amsterdam-based Music Hack Day, two intrepid hackers originating from Berlin created a musical umbrella that produces a random series of lo-fi 8-bit tones. The tones are triggered by raindrops striking the outside surface of the umbrella’s canopy and the abstract results bring to mind a warped soundtrack for the first generation Nintendo Game Boy.
Put simply, the musical umbrella works as follows: When raindrops strike the outside surface of the umbrella canopy, they are converted to tones by the the presence of twelve piezo pickup sensors which are taped to the underside of the umbrella and respond to vibration. The piezo’s are then fed into an Arduino Uno – an inexpensive and open source micro-controller popular with hackers and hobbyists, which is in turn connected to two speakers.
