Coin Cell Bounce

A project log for Gravity Assisted Blinking Coin Cell Christmas Tree

The Blinking Coin Cell Christmas Tree runs entirely off the power of a coin cell with a bit of a gravity assist.

As expected, there is a lot of bounce as the coin cell rolls down a track.  I was curious to see how much.  Here is an oscilloscope trace from one such experiment.

Fortunately, the LEDs couldn't care less about this.  I did try putting a rather large cap between the rails which removed the bounce entirely.
