ZOMBIE OUTBREAK!
SETUP AND TESTING
Use copious amounts of duct tape to fasten
your zombie (or scary object of preference)
to the zombie mounting arm. Make sure the
transmitter joysticks and switches are off or in
neutral. Turn the transmitter power on and then
turn the 12V battery switch on (it’s good practice
to turn on the transmitter before the receiver in
most R/C applications).
Fully close the valves to both air cylinders and
then open a half-turn initially (you’ll adjust these
in a bit). Carefully open the main valve on the air
tank fully. If you hear air leaks, turn the air tank
valve off and slightly tighten the compressed air
fittings at the tank, regulator, and solenoid valve.
If the quick-connect couplers seem to be the
problem, Vaseline or light grease around these
couplers will usually stop the leak. If no leaks,
then you’re good to go to the next step. Adjust
the air regulator to about 40psi.
Stand back to test left/right/back/forward
movement of the can. Refer to your specific
R/C unit instructions to adjust neutral position,
direction of movement, and sensitivity of the
controls as needed. Be careful with fast starts,
as the can may tip backward easily, especially
when the 12V battery holds a fresh charge.
Flip the appropriate switch or stick on your
transmitter to open the solenoid air valve. Adjust
the two air cylinder valves as needed for desired
opening speed. For smooth operation, the valves
should be set so that the lid begins to open just
a bit before the zombie is pushed upward. Once
adjusted, use the lock collar on the valves to lock
them in position, or simply tape them in place.
FINISHING TOUCHES
•
For an added audio effect, use zip ties
or double sided foam tape to secure an
inexpensive small motion-activated spooky
sound box inside the upper inner wall of the
garbage can. The sudden opening of the lid
should effectively trigger this sound box.
•
If you have access to a Cricut machine or a
laser cutter, make a decal for the side of your
garbage can to match your real garbage cans.
In a pinch, a paper logo affixed with double
sided tape will be good enough in the relative
dark of a Halloween night.
•
For added realism, consider hanging a banana
peel, candy wrapper, or other bits of trash
over the edge of the garbage can.
ON HALLOWEEN NIGHT
Two batteries should last one busy Halloween
night. Fully charge both before the festivities
