Building a super spy bug transmitter

www.bug-transmitter.com 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.

    …wut? o.o

  3. technozauberer says:

    yes,solder a 3.5 mm plug instead of the mic.

    can someone send me a picture of PCB that I can print it out??

    what was the previous song on this video before you changed it?

  8. izhardawer says:

    can it be detected by mobile radio.?????

    HI, good job, where is + and – on microphone ? Can I use 3.5 mm port ? Can I use computer microphone ?

    I buy all the stuffs to build it … + i make the circuit .. but nothink … i was looking to find the MHz on the radio to find my FM Bug and nothing … Its not working for me im not sure why … i done all the circuit 100% good and nothing for me … i dont know ..

  14. theaviator2180 says:

    can you help me find this “1 – 5p to 30p air trimmer” i have looked everywhere and can not find it… possibly a link to it or a replacement.

  15. Rakeshvyas45 says:

    please tell me the coil’s henry and frequency of the transmitter.

  16. Rakeshvyas45 says:

    plz tell me the coil’s henri and the feqvance of the trasmittar.

    @dazaro3

    Can you tell me where I can buy (online) the electret mic?
    Thanks.

    I only have condenser electret mic’s layign around, which require a mini driver circuit to run them.If I add the driver circuit to this, do you think it will work?

  21. aerofart says:

    Bravo! Very well done, video and project.

  22. BondisBoss says:

    not being funny or anything, but i dont really want a 35cm antenna wire coming off a bug if its meant to be discreet.

  23. T3CHNOTURK says:

    3V is the minimum voltage. the 2n3904 transistor can run on max 40v

  24. mikilofo90 says:

    Can i make portable short-wave transmitter? I want range to be alot more
