If you’re looking for a simple way to make an RF transmitter, check out [Tomasz]’s Morse code transmitter. His design uses nothing more than a microcontroller and a 16MHz crystal to transmit CW Morse ...
This series of projects explore concepts of radio communications. We use LEDs to generate (very high frequency) radio waves and photo-resistors to take the place of radio antennas. These ideas are ...
Long before pixels and cell towers, there were dots and dashes. Morse Code was the complicated mainstay communication of choice practically from the day Samuel Morse started clicking his prized ...
The wireless transmission is being demonstrated by the simple circuit which can send Morse Code signals over distances of a few meters to any AM radio. The Morse Code signal is considered as a ...
The Titanic famously (or infamously) used Morse code to call out in distress at the end of its final voyage. Ships at sea and the land-based stations that supported them used Morse code for decades, ...
How did we make our transmitter on the island? The Rough Science transmitter had the following parts: 12V car battery, Morse key switch, buzzer and transformer mounted on a wooden board and an antenna ...
Last Saturday, more than 150 listeners across the U.S., Italy, France and Japan huddled by their radios to decipher a series of Morse Code transmitted by the Maritime Radio Historical Society. MRHS ...
