This is a picture of a Bug Detector

Bug Detector Plans are required when you want to create a basic bug detector. You may want to create bug detectors for many reasons, just for fun, or to take pride in telling your friends that ‘hey I have created a bug detector’.

What you will need:

(the number in brackets is a reference number which matches the schematic. The number in paranthesise is the amount of the part needed.)

[1] (1) 1n34a crystal diode
[2] (2) 2n107 audio transistors (ge-2 or equivalent)
[3] (1) 3k ohm variable resistor
[4] (2) 560 ohm 1/2 watt resistor
[5] (1) 15k ohm variable resistor
[6] (1) 500 ohm variable resistor
[7] (1) .002 Uf capacitor
[8] (1) 1.5 Volt aa battery
[9] (1) aa battery holder
[10] (1) 0-300 microammeter (lafayette 99-g-5028 or equivalent)
[11] (1) 10 millihenry choke (ohmite z-50)
[12] (1) single-pole single-throw (spst) toggle switch
[13] (1) project box (radio shack)
[14] (1) antenna (either from an old transistor radio or a stiff piece of wire will also work)
[15] (1) 2000 ohm headset (or a miniature earphone like most tv and radios use)

the parts can be purchased from radio shack for less than $20. This is a very good high-gain meter-type bug detector. It has a crystal diode with 2 amplification stages to boost the power of the meter. This produces a broad-band, battery-powered, receiver that can sense radio-frequency transmitters up to a mile away. Unfortunately, it will also pick up a commercial am or fm station up to 3 miles away
