US researchers have used graphene to create the world's smallest FM radio transmitter. "This work is significant in that it demonstrates an application of graphene that cannot be achieved using ...

What if you could broadcast signals across the globe using just a credit-card-sized computer and a handful of components? It might sound like a scene from a sci-fi novel, but with a Raspberry Pi and ...

Engineers from New York's Columbia University have created a nano-mechanical system that can create FM radio signals. In other words, they've built what they believe to be the world's smallest FM ...

A recent Radio World ebook discussed trends in transmitters and best practices when shopping for one. Mike Cooney is executive vice president of engineering and chief technology officer of Beasley ...

The project is about the size of a standard AA battery which aims to build a single transistor FM transmitter. Having a power supply of 1.5V cell is the main advantage of this circuit. The battery is ...
