Route the wires to keep them away from the
propeller. Mount the slide switch just below the “pages”
for easy access. Put some Velcro™on the side of the
battery and mount it in the slot beside the PCB. Mount
any sound module on the other side of the prop motor.
Be careful to keep it away from moving parts. Refer to
Figure 7 for the parts placement.
Wait for an unsuspecting victim. Remember, Channel
A is for sound. When they come over to look, Channel B
is for the eye movement. People are curious. They will
normally reach to open the book. Timing is everything
here. Use Channel C or D to make the book jump at
them, then retreat. Awesome!
If you like Halloween and scaring (or startling) people,
then this is for you! NV
