What you will probably need is a type of motor driver, unless you have high
efficiency geared motors like escaps. He also has the circuits for that too.
The tutorial your going off of looks like its only a single (master) bicore,
what you need is a double (master/slave) setup, look on his schematics page.
I could be wrong though.

No... not unless you rewind them... most car motors are 12 and 18 volts and
are set up to pull high amps...

It is very possible to rewind them but is a lot easier to go the other
way... bigger wire and less turns... is what it needed for higher
performance on the track...and is very easy to do... this is why you hear so
much about custom rewound armatures at the race tracks...

For BEAM we would need finner wire and a lot more turns... this is almost
imposable to do by hand... just picture winding ten feet of wire that is
1/8th the strength of a human hare around that little armature... I've done
it with a machine winder... and still the failure rate is about one out of
20....

but you would need about 25 to 40 turns...

This is a stupid questions, but has any body tried those rotating suckers
to see what powers them? They turn real slow. I was just wondering.
