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.
Its not working BOOOO!!!!!!!!!!!!!!
…wut? o.o
yes,solder a 3.5 mm plug instead of the mic.
Thumbs up to Innercity Big Fun!
esta vacano el transmisor
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?
can it be detected by mobile radio.?????
Excellent !!

hould be a teacher,excellent vid,easy to follow and im going to give it a go.Keep vids coming,thanks for upload very informative
HI, good job, where is + and – on microphone ? Can I use 3.5 mm port ? Can I use computer microphone ?
Complete schedule on my website: silaseletronika.webnode.com
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 ..
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.
please tell me the coil’s henry and frequency of the transmitter.
plz tell me the coil’s henri and the feqvance of the trasmittar.

Can you tell me where I can buy (online) the electret mic?
Thanks.
Hi
i think you interested at this link

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?
Bravo! Very well done, video and project.
not being funny or anything, but i dont really want a 35cm antenna wire coming off a bug if its meant to be discreet.
3V is the minimum voltage. the 2n3904 transistor can run on max 40v
Can i make portable short-wave transmitter? I want range to be alot more
