Remote Control Jammer - Collection of Gag circuits, scroll to find this one. Do you have an incessant channel hopper that is driving you crazy? Or perhaps you simply want to enforce your own selections. The TV Remote Control Jammer will do the trick.
This circuit is a redo of an older design which is not effective on modern remotes. Modern remote controls are hard to jam but with a little care this circuit will do the job. The circuit is just a flasher operating at 40 kHz which is the carrier frequency used by common remote controls. The strong 40 kHz infrared flashing interferes with the signal from the remote. __ Contact: Charles Wenzel of Wenzel Associates, Inc.

Remote control turns battery on & off - 09/12/97 EDN Design Ideas: The circuit in Figure 1 acts as a latching solid-state relay. A short application of a magnetic field in the vicinity of S1 toggles the relay on and off. The relay switches power from a 3V battery at load currents as high as 10 mA. This remote switch is ideal for battery-powered applications. in the off state, the circuit draws no current; in the on state, the circuit draws only 100 µA. All the parts are inexpensive and readily available. Design by Allen Harstine,Integrated Measurement Systems Inc, Beaverton, OR
