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 ...

A team of engineers from Columbia University has created a nano-mechanical system with the ability to create FM radio signals. In other words, they've built what is effectively the world’s smallest FM ...

Join radioqualia’s Adam Hyde for a workshop on building mini-FM transmitters at The Physics Room. This is a rare opportunity to engage with the world renowned New Zealand new-media artist to build ...

The new breeds of IBOC transmitters on the floor at the NAB2004 convention in Las Vegas weren’t that big – and they’re anything but generic. Implementation choices for FM IBOC range from low-level ...

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 ...

Increasingly iPods are finding their way into automobiles. Currently there are three ways to play those iPods through your car’s sound system—via a direct cable connection, through a cassette adapter, ...

The heart of every radio transmitter is a reliable oscillator. Creating small, and tunable, oscillators that can maintain a precise frequency when conditions like temperature, pressure or humidity ...

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 ...
