Introduction: Long Range Spybug.

I am going to show you a step-by-step process to building a spybug from common electrical componenets.

Step 1: Components

Components list

Part

  1. C1  1n disk capacitor (102) 1 pc.
  2. C2  5.6pF disk capacitor(562) 1 pc.
  3. C3, C4 10 uF Elec. Capacitor(25-50v) 2 pcs.
  4. C5 3-18 Trimmer Capacitor 1 pc.
  5. R1 330 ohm 1/8 w  Resistor 1 pc.
  6. R2, R5, R6 4.7k 1/8 w Resistor 3 pc.
  7. R3 10k 1/8 w Resistor 1 pc.
  8. R4 100k 1/8w Resistor 1 pc.
  9. Q1, Q2 2N2222 NPN Transistor 2 pcs.
  10. L1, L2 5-6 turns copper coil 2 pcs.
  11. 10mm Electret microphone 1 pc.
  12. 9v battery and clip

     All Resistors can be substituted with 1/4 watt. The transistor can be substituted with a 2n3904-06 transistor. 

Step 2: Schematic

Here's the schematic, any questions leave them I will answer quickly as possible.

Step 3: PCBV Layout

Here is a picture of the PCB that I made for this spybug, or you could just make it on perfboard if you want. 

Step 4: Resistors

First I soldered the resistors on just below where the mic will go. These are R5 & R6.

Step 5: Adding Components

Next I add C4 (10 uF cap), Q1,Q2 (2n3904 transistor) & R4 (100k)

Step 6: Adding Components

Next step I add the electret microphone, and the two coils. The coils should be wrapped around a 1/4 inch drill bit 6 times to get the coil needed for this project.

Step 7: Adding Components

Now I add C1 (102) capacitor, R1 (330 ohm res.), R3 (10k res.) and C4 ( the other 10uF capacitor)

Step 8: Adding Componenets

In this step I add the last resistor (R2), then I checked to se if every coponent is where it should be just to be sure.

Step 9: Adding the Trimmer, Etc.

Finally comes the trimmer cap, the battery connector and the antenna wire. I chose to use a braided copper wire for this antenna just to try it but you can use whatever you like.

Step 10: Next Week the FM Phone Bug.

Next week I will be adding a new Instructable, the FM phone bug. This will hook up to one of the 2 phone lines

    I made one but could not work. Why? Tell me. I made as U told in the diagram

    Is 100mt a long range?

    it says "5-6 turns of .5 dia wire" what measurement is .5?

    gauge/thickness/diameter

    i meant is it in milimeters, or other type of measurement

    i think im on the wrong page/thread https://www.instructables.com/id/Making-a-simple-spybug/
