One of our favorite purveyors of electronics knowledge is at it again. This time, [Afroman] explains how frequency modulation works while building up a short-range FM transmitter on a board he has ...

Use the Raspberry Pi as an FM transmitter. Works on every Raspberry Pi board. Just get an FM receiver, connect a 20 - 40 cm plain wire to the Raspberry Pi's GPIO4 (PIN 7 on GPIO header) to act as an ...

Though only the richest auto buyers could afford a car with an AM-FM radio in the early 20th century, virtually all cars now produced in the United States come with one. However, those who prefer to ...

I put some portable FM transmitters to the test to see which ones deliver the cleanest signal, easiest usability, and best ...

The Si47xx series of integrated circuits from Silicon Labs is a fascinating series of consumer broadcast radio products, chips that apply SDR technologies to deliver a range of functions that were ...

Let’s construct a low-power FM transmitter using surface-mount devices (SMD) that will be received with a standard FM radio. Soldering surface mounted devices is not so hard and actually is quite easy ...

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 ...
