Motors & Mechanisms
Motors are what make props move. This page covers the common motor types used in home haunts, how to power them, and how to connect them to props. For the mechanical side of converting motor rotation into prop movement, see moving props without pneumatics.
Wiper Motors
The most popular motor for home haunts. Salvaged from junk cars or bought online for $10-20. They run on 12V DC, are weatherproof (designed to work in rain), and produce strong torque at low speed. The output arm sweeps back and forth, which is perfect for props that rock, swing, or raise an arm.
Power with a 12V DC power supply (wall adapter or car battery). Speed can be controlled with a PWM motor controller module ($5-10).
Rotisserie Motors
Very slow continuous rotation (1-3 RPM). Battery powered. Used for the flying crank ghost and any prop needing smooth, slow turning. Available at hardware stores or online for about $10-15.
Deer Motors
Motors salvaged from animated Christmas deer displays. Similar to rotisserie motors but often have a cam mechanism built in for head-nodding or leg-lifting motion. Check thrift stores and post-Christmas sales.
Servo Motors
Small, precise motors controlled by an Arduino or similar controller. They move to a specific angle and hold position. Used for turning heads, moving jaws, and other small precise movements. Not strong enough for large or heavy props.
Power Supply Notes
- 12V DC motors: use a 12V DC power supply rated for at least the motor's draw (usually 2-5 amps). Old laptop chargers that output 12V work. Car batteries work for portable setups.
- Servo motors: powered from the Arduino's 5V pin for small servos, or a separate 5-6V supply for larger ones
- Always use a fuse or circuit breaker appropriate for the motor's current draw
- See electrical safety for outdoor power considerations
