Many thanks to talkingelectronics. In this video we are showing you how to make a FM transmitter Bug using 2 transistors and with a transmission range of 800 meters !! This FM transmitter Bug is very easy to build. The size of the circuit board is ONLY 21mm x 15mm. 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 ,21mm X 15mm BC547 transistors x 2 1nf ceramic capacitor 10pf ceramic capacitor 33pf ceramic capacitor 22nf axial ceramic capacitor x 2 1 - 5p to 30p air trimmer 470R resistor 10K resistor 47K resistor 68K resistor 1M resistor 10mm Mic 175cm antenna Battery Plug Some solder 19mm heatshrink
