| Dec 27, 2012 at 12:49 | comment | added | Watson | The Joule Thief converts to a higher voltage which could be dozens of volts if not regulated. As long as the device being powered does not use more power, the JT will convert to somewhere around the voltage required. But the amount of power converted is directly related to the battery voltage, which changes as the battery discharges, so there has to be something to compensate for the change. Simplest is to stop the voltage from rising above 5V for example, by adding a zener diode. The more complicated way is to use one of the circuits in the links I gave. Or use an IC made for this. | |
