a sister project to go with the wind speed is a lightning sensor .
its a W I D E tuned RF tank peaked at 2 MHz and a amp to up the sig to a level to trigger a cam.
most of the triggers use Light but here is the idea
lightning has 2 parts . a dart leader or strike leader . and the main bolt .
With a Light based one you can't use the pre strike as a trigger .
With RF you can!
the circuit is super simple
a LM386 amp and a LC tank . the base idea was a Xtal set .
I just need a storm to test it with . but so far a 3MHz pulse works accross the lab well so Ill bet a strike will too.
