Vibration motors can be found in telephones, tablets, and other electronic devices. They're available on the market and extremely affordable:http://www.aliexpress.com/snapshot/233098463.html?orderId=1125252124 The device in this Thing moves around by vibration. Four small toothbrushes are detached from their holder and positioned underneath a platform, containing two vibration motors and two AAA batteries. The motors are designed for 6-9 volts, yet they work perfectly well at 3 volts too. The battery compartment is sealed with a lid that's held in place by a rubber band. The contact points are short M3 screws, secured with matching nuts and washers beneath which the wiring is clamped. No soldering is required. The lid features openings for four 5mm LEDs. Simply turn it on, give it a push, and it starts moving at an incredible speed. Attempting to hit a target at some distance using this interactive Thing could make for a fun game for kids. This model should be printed with the cylinders upright.
