# The motor

If you're going down the steering-wheel-motor route, the Phidgets is the one to buy. There are alternatives, but PotatoFarmer has made an excellent 3D-printed holder that fits it nicely (see below)

Note that if you're using a 24V motor as above, you'll need a 12V-24V step-up converter, sample here.
