Piezo-powered Tambourine by Jie Qi
An electric tambourine that is completely powered by the playing of the instrument. Yellow LED lights on the jingles light up when the corresponding piezo is rattled. The harder the tambourine rattles, the greater the voltage generated by the piezoelectric elements and thus the brighter the light. If the tambourine is rattled with enough force, blue and red LED lights on the band also light up. Thus, the player can both hear and see the music generated by this instrument.
