Simple 2 Pin Crystal Circuit !

Quite the elegant and simple solution to the problem of reliably driving 2 pin crystals.
The circuit, by K5FOBS has a good description along with it and can be found here: http://jaunty-electronics.com/blog/2012/08/simple-oscillator-as-crystal-tester/

Now we just have to find a way to ramp up the output to 20V !
