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 ...

The chances are that many of you will have made an FM “bug” style transmitter, a simple one-transistor oscillator usually driven by a small electret microphone. It’s also relatively straightforward to ...
