The source is extremely 20 difficult to locate because of the way that high frequencies can penetrate objects and trick our ears. You have probably encountered something similar in the real world such as a failing appliance, noisy video screen, or even a beeping wrist watch buried deep in a couch. As you know, high-pitched sounds seem like they are coming from all directions, which makes tracking them to the source a real chore. Add the fact that the sound only happens once every several minutes, and it may drive a person loopy as they spend all day looking for the source of the sound.

If you need a little more response from the solenoid or motor you are using, there is no problem running the circuit up to 12 volts, but if your actuator is very low impedance, you may need to use a transistor driver circuit to source the needed current or your 555 may get hot in a hurry. Since there are only four components in the circuit, it can be built any way you like, even on a bit of cardboard by soldering the leads together after punching them through the board. 5-inch square board I have mounted it to (see Figure 3-3).

The schematic is shown in Figure 3-18. You don’t need to place the power switch in the actual box, and it may be easier to conceal the towing mechanism if the switch is remotely placed away from the box. For a living room scenario, place the towing box under the target couch, Motor Switch + 12 V Figure 3-18 Motor, switch and battery schematic Figure 3-19 Towing system ready for action 42 table or chair with the switch remotely connected via wire so that you can press it inconspicuously as your pals stare at the TV.
