Clocks are an effective place to hide listening devices.
At times you may need to eavesdrop on what is being said in another room, either for security reasons or as part of a prank. One way to keep track of the sounds coming from a particular room is with a spy clock. It may look like an ordinary, functioning clock, but it actually transmits all audio within range of the microphone. Spy clocks can be purchased at stores that sell surveillance equipment, or you can make your own.
Instructions
1. Buy a set of cheap walkie talkies. Set one to the side for later. Open the second walkie talkie so that all components are visible. Do not worry if you damage the plastic case; it will not be needed.
2. Find the wires that lead to the walkie talkie's battery pack. Use wire cutters to clip the wire as close to the battery pack as possible, leaving the longest possible length of wire connected to the circuit board. Cut the wires for the microphone and speaker in the same way. Lift out the circuit board.
3. Push in the switch that makes a connection whenever the walkie talkie's talk button is used. Hold the button in and super glue it into position. Hold the button in place until the super glue is dry (about one minute).
4. Open an electronic clock that uses batteries and has a speaker. Do not cause any visible damage to the outside.
5. Use the wire cutters to strip the insulation from the tip of each wire connected to the walkie talkie circuit board. Locate the wires running from the clock's battery back and note the position where they are soldered to the clock's circuit board. Please the uninsulated tips of the walkie talkie's battery wires onto these solder points and use a soldering iron to melt the solder around them. The walkie talkie circuit board should now receive power from the clock's battery pack.
6. Solder the remaining wires from the walkie talkie's circuit board to the clock's speaker. This will allow the clock's speaker to serve as a crude microphone. Alternatively, you can place the walkie talkie's microphone inside the clock, but this may produced muffled sound.
7. Position the walkie talkie circuit board inside the clock so that the cover can close all the way and where it will not interfere with other components of the clock. Use super glue to hold the circuit board in position, if necessary.
8. Close the clock. Be careful; the clock must not appear as though it has been tampered with.
9. Place batteries in the clock and set it up in the room. Take a position a short distance away with the other walkie talkie. The other walkie talkie will receive the audio from any sound made in the same room as the clock.
