    Hey guys I'm trying to make a device that heats up fairly high to heat up coals. The coals are fairly small maybe the size of a half dollar. I wanted to make something simple and wanted to know if i could take a cigarette lighter coil and connect it straight to a battery or would i have to make a circuit and a separate heating coil.The power supply could be anything but preferably 5-12 volts.

    if a cigarrete lighter from a car has high enough temperature then I see no problem with connecting it to a power supply like an ATX one, but be aware that it will need some large amount of current, like 10A or so, so you should use thick wires to connect it.

    You can buy nichrome wire (which is used for things like toasters, car cigarette lighters, etc) on reels from electronics suppliers or shorter lengths on ebay and select the gage most appropriate.
    There's a calculator here, but if the wire isn't in free air then it won't be accurate, probably give you an idea though.
