The AM transmitter can be used near an AM radio that is tuned to 1000 in order to hear the sound source from the user in the AM radio or send voice and music across the room or street. The heart of ...

There are not many AM transmitters that are easier to build than this one because the inductor is not tapped and has a single winding. There is no need to wind the inductor as it is a readily ...

Last week, Tech Talk looked at listening to internet radio at home when the computer is in one room and the listener is in another. A sharp reader, Guy Chambers, has sent in his own solution, and it ...

Over long cable runs, an isolated 4-to-20-mA current loop offers robust noise immunity and tolerance. This characteristic makes it popular for analog data transmission in noisy industrial and process ...

Abstract: This paper presents a voltage-controlled oscillator (VCO) operating up to 250degC and usable as a simple frequency modulation (FM) transmitter in wireless sensor networks (WSN). The device ...

[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 ...

[Dino] got his hands on an FM transmitter “bug” kit via a friend, and thought it would make for an easy and fun Hack a Week project. The kit is simple two transistor half-wave FM transmitter, which ...
