High Voltage Joule Thief Circuit. Make a joule thief. The super joule thief can do just that.
It can increase the voltage of a power source by changing the constant low voltage signal into a series of rapid pulses at a higher voltage. Make a joule thief. This way you save yourself a little work and wire.
A joule thief circuit is basically an efficient self oscillating voltage booster circuit built using a single transistor resistor and an inductor which can boost voltages as low as 0 4 v from any dead aaa 1 5 cell to much higher levels.
The normal output is a series of current pulses but a diode and a capacitor can turn this into a steady dc voltage. This circuit is also known by other names such as blocking oscillator joule ringer vampire torch. It can increase the voltage of a power source by changing the constant low voltage signal into a series of rapid pulses at a higher voltage. You can even take a battery that other devices will consider to be drained and get a bit more of the energy out of it.
