We completed our prototype of the TuneDroppa. It consists of a cheap demo umbrella (the real one will be transparent and of a “bubble” design), one contact mic, one blue LED, and our breadboard/arduino setup. We also added a 3 watt amplifier and a 4″ speaker to amplify the tone that will be triggered by raindrops. The tone is currently being generated by the Arduino, but we’re hoping to use some 74C14’s as oscillators eventually. This is just a proof of concept, and it seems to be going well!
