Sound Effects: Race Car Sound Effect

Easy to build Gun Sound Effects generator kits, also inludes several different sounds and tunes.

This circuit is an alarm for the home, car and a lot more. It employs a magnet and reed switch to trigger the circuit. An intergral piezo sounder produces the alarm sound (100dB). There is also a relay capable fo handling up to 10 amps that will switch wh

This is a RC car project is the transmitter and receiver modules for a Remote Control car, with speed control and continuous steering.

It's snail-like design may give a lethargic impression but, contrary to first impression, COMET is quick to respond and scurries speedily on command.

An exciting way to demonstrate the use of alternative energy. It features an aerodynamic sports car shell design with a transparent car body that can be painted or left clear to view the inner mechanics, 4 wheel chassis, powerful 1.4 volt - 350mA solar ce

Extremely useful electronic circuit capable of producing a variety of cool sound effects.

Flash you car's headlights on/off, either together or alternatively, with this flashing lights electronic circuits. Don't know if it's legal but it's pretty cool :)

This page links to two electronic circuits. Once circuit produces emergency siren noises (police, fire, ambulance), and the other is a chime type sound effect.

ElectroKits will soon provide the ultimate in car kits

This mini-VOX - voice operated relay - is based on a circuit published in Silicon Chip, 9/1994, p31.

Sound turns on the transmitter, which operates in the FM radio band. A neat way to catch a thief in another room or garage. The volume of sound needed to trigger the circuit is adjustable. The two stage transmitter has good range and the circuit powers do

A stronger, Mecha-Medusa is a walking robot that operates with the aid of a sound sensor. Clap hands or snap fingers to command this robot to start walking on four legs. Stops automatically after a preset time. Ideal for the hobbyist or budding scientist.

Simple schematic for a doorbell electronic circuit that produces a ding-dong sound when your visitors presses the door-bell button. Based on IC 8021-2.

Adjust the sensitivity of this circuit to control a Relay that can turn on whatever is connected to the contacts of the relay. Very practical circuit for a variety of projects. Turn on a light when your dog barks, or set of a siren when an intruder makes

This kit is a great introduction mechanical gear and motor operation.

Dick Cappel's page illustrates an extremely basic small FM transmitter that rebroadcasts sounds using a 1.5 Volt battery. very simple circuit.
