A simple fm radio transmitter circuit which covers frequencies from 88 to 108 MHz. It is built with 3 transistors: BC109, BFR91A and BFR96S. It is quite stable and the output power is around 200 mW.

[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 ...

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 ...

Smallest FM radio transmitter just created using graphene by the wizards at Columbia University. This one is pretty cool and I certainly do not want to butcher the idea and explanation behind it all.

One of the easiest, simplest ways to make an FM transmitter is to buy this kit from BuildCircuit. It’s amateur friendly, so anyone should be able to use it. What you need for assembling this ...

[Dino] got his hands on an FM transmitter “bug” kit via a friend, and thought it would make for an easy and fun Hack a Week project. The kit is simple two transistor half-wave FM transmitter, which ...

Scientists have taken advantage of graphene's special properties -- its mechanical strength and electrical conduction -- and created a nano-mechanical system that can create FM signals, in effect the ...

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 ...

If you are looking for an easy weekend project, you should check out our list of 5 easiest simple FM transmitters to make at home. When you were a kid, you had probably wished you knew how to make all ...

Spätestens Ende 2026 wird die Verbreitung von allen Radiosignalen via UKW in der Schweiz eingestellt, die SRG stellte ihr Signal schon Ende 2024 ab. Wer danach noch Radio hören will, braucht DAB+.
