    I have a joule thief outputting from around 100v-700v and when it gets a load it is right around the 120 volts. The problem is that when for example i plug in a USB phone charger, it flashes from the high hertz. How would I go about regulating this? Thanks -Josh

    Regulate the 17 khz coming out of a joule theif to around 60 hz

    Can you post a schematic of your Joule thief circuit?

    There's no way you can convert that circuit to run at 60Hz if it's designed to work at ~17kHz. It's also unlikely that the circuit can provide anywhere near enough continuous power to supply a USB charger.

    Yeah, the transistor already tried to kill itself on a 23w bulb!
