LED flashlight PWM in the rain
« on: January 13, 2017, 04:38:07 am »
I just happened to point my LED flashlight into the rain last night and saw what only  a serious geek would get excited about.  And since that covers present company I will share.

What I observed was linear streaks with on and off times consistent with the duty cycle. 

Need to figure a way to photograph it.

Try looking at a spinning wheel with it.
