How do you convert 6v to 12v? Here are some of 6V to 12V DC converter circuits that can be used to convert a small voltage of about 6 volts to a higher voltage of 12 volts but of course with a lower ...

Here is a simple 12 V inverter for using a small soldering iron (25W, 35W, etc) in the absence of mains supply. It uses eight transistors and a few resistors and capacitors. Transistors T1 and T2 ...
