Many thanks to talkingelectronics.In this video we are showing you how to make
a very small home made FM transmitter Bug using
a single transistor and with a transmission range
of 200 meters.

This FM transmitter Bug is very easy to build.
The size of the circuit board is ONLY 22mm x 10mm.


I design the circuit board layout using
Pain shop pro X2 ,it takes me 4 hours to get
the design right ,i want a very small PCB.

To make the PCB i will be using the toner transfer
method and Ferric Chloride.



Parts used:

Home made PCB

2n3904 transistor

4.7p ceramic capacitor

1n ceramic capacitor

22n axial ceramic capacitor

1 - 5p to 30p air trimmer

360R resistor

4.7K resistor

10mm Mic

35cm antenna

Battery Plug

Some solder

19mm heatshrink

Total cost just 90p.
