This is designed to test your nerves by causing a light electric shock when the probe plate is held and the wires connected. The potentiometer allows one to increase or decrease the level of the shock.
This kit flashes a very bright white light. Never worry again about not being seen if you have to stop on the road. It comes with a plexiglass tube, end caps and lighter plug.
This kit allows you to plug any 110V light or string of lights (up to 100 watts) into the socket and watch the interesting light effect as lights alternate between bright and dim. Great for displays or holiday lights.
This power supply kit provides regulated 0 to 9 volts up to 100mA. This compact power supply is great for low current applications. Components: 2 resistors, potentiometer, 4 capacitors, 4 diodes, 3 transistors, transformer, slide switch, line cord. Principles taught: rectifiers, voltage regulation.
The kit alternately flashes two pair of LEDS at a rate of about 2 flashes per second. This is a fun toy as well as a great way to learn how oscillators work.
This kit can be used as a game, or just to drive someone crazy. The circuit produces an irritating pitch for about 8 seconds and then shuts down for two minutes. It then repeats...and repeats, etc. until found by the victim.
With this kit you can build your own transmitter that can be heard on any FM radio with a range of 40ft. Includes a miniature condenser microphone. 9V battery not included.
This kit produces a clicking sound similar to that made by a dying fish. Put the completed kit in a watertight container and suspend from the boat or dock into the water. Hungry fish come to investigate. 1.5V battery and connector not included.
