Morse Code
There are many ways to communicat in morse code. The most common is with audio tones, but there is a long history of other methods. The Navy used Aldis lamps to flash morse code between ships with directed beams of light that were dificult to intersept. A Wig-wag flag can be used. Dipping the flag to the right represents a dot and to the left represents a dash. Thomas Edison allegedly proposed to his wife by squeezing her shoulder in morse code. I have heard that smoke signals can use large and small puffs of smoke to represent dashes and dots. I have also heard of ham operators using vibrating wrist bands to communicate silently using morse code. It is even posable to use Morse Code to knit a message into fabrick. Tapping on a pipe is a classic you see all the time in fiction, but I’m not sure how it would work unless you could somehow let the pipe resinate for a dah and damp it for a dit. Once you have learned it I’m sure you can think of other ways to use it.
Timing Information
- dit lenght in seconds = 60 / (50 * target wpm)
- dah lenght = 3 * dit length
- Intra-character space = 1 dit length
- Inter-char space = 3 * dit length
- word space = 7 dit lengths
- Farnsworth Unit = (( 60 / Farnsworth wpm ) − (31 * dit length))/ 19
- Farnsworth char space = 3 Farnsworth units
- Farnsworth Word space = 7 Farnsworth Units
