[gpsKlaus] built this little FM radio (translated) based on the AR1010 IC. That chip is controlled via I2C by an ATtiny45 microcontroller. His tuning implementation relies on presetting 16 stations in ...

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 ...

The variable capacitor C1 and L1 will constitute the tank circuit which will produce the high frequency signal, the capacitor C1 is variable so that we can produce different frequency signal by ...

[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 ...

Researchers at Georgia Tech have found a way to harvest energy from electromagnetic waves in the air. The harvesting devices are produced using an inkjet printer and can collect small amounts of power ...

In the video below, the process of making this simple radio FM transmitter is explained in details. The project starts with wiring the mono phone plug to an audio source like an mp3 player. Once ...
