When the first radios and telegraph lines were put into service, essentially the only way to communicate was to use Morse code. The first transmitters had extremely inefficient designs by today’s ...

This project uses two Arduino to communicate with each other using light by means of Morse Code. As a more advanced project, it has some complex array usage and investigates converting switch inputs ...

Magic Morse is a mathematical algorithm that [Ray Burnette] wrote a few years ago to make it easy to send and receive Morse code. When he first wrote it, he designed it for a PIC, but since then he ...

The robotic Japanese cargo vessel now en route to the International Space Station is loaded with food, clothes, equipment — and a set of tiny amateur radio satellites, including one that will write ...

Information could potentially be stored in ice for millennia, simply by making subtle changes to the shape and position of internal bubbles, which can then be converted into binary or Morse codes.

On July 12, 1999, the nation’s final message in Morse code was sent out to sea from a remote Bay Area radio station. The end of an era, the room’s mood was mournful. Grizzled old men wept. “We wish ...
