How to Make a Bug Detection Device | Techwalla.com
Bug detectors are electronic devices that have the capability to detect the radio frequencies being transmitted by listening devices. This makes it easy to know if someone is eavesdropping on your conversations. Although these devices usually cost $100 or more to buy, you can make your own using items from an electronics or hardware store.
Find an electronic bug with a radio frequency detection device.
Step
Use the wire stripper and take off the insulation from the copper wire.
Step
Wrap the copper wire around the end of the toothpick using one end of the copper wire. Count the turns and stop at the 20th turn. Glue the end of...

These tags are essentially an LC tank circuit that has a resonance peak anywhere from 1.75 MHz to 9.5 MHz. The most popular frequency is 8.2 MHz. Sensing is achieved by sweeping around the resonant frequency and detecting the dip. Deactivation for 8.2 MHz label tags is achieved by punching a hole, or by detuning the circuit by partially destroying the capacitor. This is...
