Sounds like something pretty small for either a vacuum or anything in a car.
I was thinking maybe more like a hobby shop for robot experimenters or
miniature car models.  And I don't need it for the contest, I have 2 spare
control boxes and ended up doing the temporary fix on the motor on the one
that died anyway... so I still have one good spare box to get through the
weekend.
