Joule Thief Circuit Diagram – DIY Electronics Projects Joule thief circuit is an oscillatory voltage booster which can boost small amount of voltage around 1V or less to a usable voltage to drive small loads like LEDs. The joule thief circuit extracts almost all energy from a standard single cell. Joule thief circuit powering a compact fluorescent lightbulb The normal joule thief circuit has only two coils, but as you can see in the above circuit diagram, this one has three. That third coil and the CFL are the only additions to the regular joule thief circuit. There's also one change and that's to change the normal low power transistor for a power transistor. : RF bug detector anti spy detector with anti ... : RF bug detector anti spy detector with anti thief alarm for hidden camera mini Camera , upgraded Wireless Pinhole Camera detector with flashlight: Home Audio & Theater Transformerless Joule Thief Electronics DIY Transformerless Joule Thief The "Joule Thief" circuit that does not use a transformer to power LED from a single 1.5V battery cell.
