Does anyone know what happened to Watson's blog?

i know this isn't a joule thief..
but the jt folks are more likely to use this than the desk jockeys.. out there..
if you use 9 volts and higher use a small 90v neon bulb with a diode to the battery..
if tuned right you can double your run time.. this is a ferrite core from a junk flyback coil..
i used a dual pot but it measures 2.2 k .. puts out a mod sine wave..
transistors or mosfets work.. fet have a cleaner sine wave..
the trick here is to not use the batterys voltage so use a diac , sidac , or even gas discharge tubes rated high than your battery volts.. just catch bemf back to the battery on the side that the transistor is in the off position so the volts feed back go in the battery and not the coil..
