Yes, by some black magic that I fail to understand.  The voltages involved
are actually higher... 12v.  I have actually gone higher, I'm running my
printer at 14v now, that's as high as the power supply I have goes.  I have
a 24v one in the cupboard, I am thinking about going to that voltage.  Still
trying to work out if and what I will damage doing it!!

ok that is what ill get.

This is probably a dumb question but this ones voltage is 2.8 volts, the
arduino is 5 - 9 volts. Do the motor drivers deal with this for us?
