In this video we are showing you how to make
a tiny FM transmitter Bug using 1 transistor and
small SMT 805 parts.

This FM transmitter Bug is very easy to build.
The size of the circuit board is ONLY 9mm x 9mm.

I design the circuit board layout using
Pain shop pro X2 ,it takes me 2 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 ,9mm X 9mm

SMD 2N3904 transistors x 1

All capacitors and resistors are SMT 805

1nf ceramic capacitor x 1

10pf ceramic capacitor x 2

33pf ceramic capacitor x 1

22nf axial ceramic capacitor x 1

1 - 5p to 30p air trimmer

100R resistor

5.6K resistor

3mm Mic

165cm antenna

CR2032Battery holder

Some solder
