As I have been asked elsewhere about the circuit in this I will post a schematic.

The problem to be solved was this:

SenKat red needs a regulated supply of ~3v
Motors need a supply of ~1.5v
Battery to be used 9V

The answer?
Use an LM317 driver and use the motors in parallel with a resistor to set the current for the LD (they run from the 1.25v ref voltage) ;)
A word of warning though, when you are playing about trying to set the motors up do not allow the wire to the motor to touch each other....it allows 1A to get to the diode..... ::)

how did you engrave the zippo
There is an ebay seller who will engrave whatever you want on the lighter, it isn't a zippo but at £7.50 engraved and delivered not a bad deal.
