SolarSonic Impulser Ping-Pong

More fun with sound, speakers, and styrofoam balls. This also uses my "SolarSonic Impulser" method to toss the balls back and forth using a small solar cell and speakers as the "actuators".

The circuit itself is not shown, but a small solar cell charges a capacitor until the trigger circuit senses adequate charge and sends a pulse of current to a small speaker. The speaker (really working more as a solenoid or basic linear motor in this case) moves abruptly and knocks the ball back to the other side.

This project was shown at Maker Faire Bay Area in 2019 along with a couple more items that utilize this basic principle.

The concept of using a small solar cell and a circuit to charge a capacitor and then provide short but relatively powerful pulses of power is commonly implemented using the Miller Solar Engine (MSE) circuit. The MSE has been used for in a variety of projects for many years and I learned about it from Solarbotics. They have several projects that use a MSE to drive marble rollers and similar kinetic art. The circuit I used is modified from the standard MSE to better fit my application.
