[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 ...

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 ...

To build this simple radio transmitter, you will need to gather the parts such as a 9V battery, a clip, wires, a prototype board, a trimmer capacitor, a resistor, an audio plug, etc. From tools, ...

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.

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 ...
