built with an LM339 Quad Comparator

Improvement needed; Changing the frequency doesnt the change the charge rate of the capacitor, so the duty cycle adjustment pot needs to be recalibrated for the new frequency.  this will be necessary to connect this to circuits that can shoot through if both inputs are high
