In this video I'm demonstrating an analog computer that models a bouncing ball, with control voltage and trigger outputs that could be interesting with synthesizers, sequencers, etc. I designed the circuit as an excercise in understanding analog computer techniques. I found that almost all textbook descriptions of analog integrators are incomplete, lacking adequate description of how to set the initial conditions of the integrator and reset it at the end of each computation. An obvious application of this particular circuit is to generate nonlinear rhythms for electronic music... check out Aphex Twin's track "Bucephalus Bouncing Ball" for a good example of this effect. more info: ericarcher.net Many thanks to Matthew Thies for filming and editing this video. -Eric Archer 2009
