Containerized Particulate

Yes indeed. Some of the subtleties of velocity differentiation are lost on this video, but if nothing else, it’s made these bells much less irritating to listen to. Low PWM and high frequency also yields some very cool modem / printer like tones. What’s even less obvious is a total rewrite of the code, which should make it a breeze to upgrade this thing to a 3 octave glock + Arduino Mega.
