How to make a personal stereo blocker?
Based on teh fact that mobile phones can cause intereference in personal music players, is it possible to apply the same principle and create a device that can cause interference to closely located music players?
Answers:
Remove the filtering cap on any large brush type motor (vacuum cleaner). A similar effect can be had by removing the filtering capacitors in your cars ignition . if you want to extend the range of your interferance add a long length of wire to one of the brushes, of the motor. but be prepared to get a visit from the local radio authorites it is usually illegal to cause such interferance and you can be traced. spark gap interferance would work the best, Nikola Tesla is known to have wiped out hundreds of radio receivers with his with discharges consisting of millions of volts, and up to 135 feet long at Colardo Springs.
yes. just take a pair of scissors to the lead.. when they arn't looking.. and quickly shuffle away..
It is possible to make a device that will block out the sound of a stereo. You need to make a device that inverts the sound and when pumped out of a loudspeaker the waves cancel each others out and its almost silent.
A device like this was demonstrated on Tomorrows World in then 70's, or possibly, the 80's, but I have no idea if they are commercially available.
Not sure if this is what you meant, but I hope it helps.
consider inventing a small nuclear (or other) device that generates an micro Electro Magnetic Pulse burt - that should wipe out any electronics in the near vicinty.
there are some potential pitfalls
you might wipe out other desirable electronics (like train / car control systems
failing that consider buying a pair of small pincer type pliers to sever the headphone cable
