6 to 12 Volt Power Supply Inverter

This inverter circuit can provide up to 800mA of 12V power from a 6V supply. For example, you could run 12V car accessories in a 6V (British?) car.
The circuit is simple, about 75% efficient and quite useful. By changing just a few components, you can also modify it for different voltages.
