Electric OU: Supplement: The Secret of DPDT

Manny the manual mosfet oscillator is supplemented with a relay board. The double-pole double throw relay is used to flip the polarity of any incoming applied DC voltage, turning it into an AC square wave output of any combination of duty cycle and low frequency desired. This AC output can be used, just like a function generator, to drive the NERD or Tar Baby circuits in either or both modes of its operation. This entire circuit, including the 12v 5ah battery, cost less than 30 dollars, and can be adapted for a variety of purposes. Please watch the Mosfets, How Do They Work series for the development and explanation of all the elements of the Manny manual mosfet oscillator. Thanks for watching !!
