LucidScience once again amazes us with a very interesting project: to build a micro-transmitter FM share recovery an old radio . A microphone
, a 9V battery , a ' FM antenna, a pair of resistors , transistors and capacitors are all that we need to just put a radio transmitter. With a radio
in any radius of 9 feet you can listen to the sounds recorded by the microphone in the specific frequency antenna installed at the transmitter.
Here you will find the link to the tutorial in English on LucidScience
