October 23, 2006
Give the little witches and warlocks a real trick when they come clamoring for treats on Halloween with this doorbell-activated soundtrack. All that's required to build this spooky sound generator is a moderate hack of a cassette player, which involves opening the case and rewiring the motor for remote control, and rewiring of your doorbell circuit. Add a simple, roof-mounted speaker, and you'll have the little darlings scattering in every direction at the first blood-curdling scream.
