Built with the Lego Mindstorms EV3 megakit, Jason of JK Brickworks has conceived a telegraph that transforms Morse signals into printed text.
In the following video you can see it in operation.
A sensor interprets Morse code keystrokes letter by letter. The printer then reproduces the text that it has converted from the dots and dashes on paper with a gel pen.
Without doubt, the most original declaration of love transmitted in all of history is that of the prolific American inventor Thomas Alva Edison (1847-1931), who taught his future wife Mary Stilwell how to communicate through the telegraph during their courtship. The day he proposed to her, Edison simply patted her hand gently in Morse code. She answered him in the same way with a "yes, I do." Now with this development in Lego pieces you don’t have to learn Morse to do something similar.
