The circuit was designed to produce a 500mW output power transmitter whose signal modulated by FM using four transistors. Transmitter – an electronic device that can produce or amplify a carrier wave ...

[Angelo] is only 15, but that doesn’t mean his fabrication skills are limited to Lego and K’Nex. He’s built himself an amazingly well constructed FM transmitter that’s powerful enough to be received a ...

Making your own FM radio is practically a rite of passage for hackers. How about making a small FM transmitter? Originally designed by the Japanese multimedia artist [Tetsuo Kogawa], this simple FM ...

Here is a simple USB FM transmitter that could be used to play audio files from an MP3 player or computer on a standard VHF FM radio by connecting it to an USB port. The circuit use no coils that have ...

I hope this is the right forum, it is sort-of about audio. I've been wanting to build a nice headphone amp for quite some time. But, I decided to get my feet wet with a little FM transmitter kit I saw ...

Placing a sheet of atom-thin graphene into a feedback circuit causes spontaneous self-oscillation that can be tuned to create frequency-modulated (FM) signals. Changyao Chen, Sunwoo Lee, Columbia ...
