MyMorse is a hands-on audio-visual telegraph key simulator that introduces students to telecommunications history, binary encoding, and rhythmic pattern deciphering. By tapping short pulses for dots (•) and holding longer pulses for dashes (—), learners interactively trace letters through a live branching binary decision tree.
In addition to auditory tone synthesis (600Hz sine wave telegraph tone), the application features a visual constellation map of English letters. The tree branches dynamically, demonstrating the algorithmic structure of prefix-free encoding and Huffman coding principles used in modern computer science.
Pair students up: one serves as the telegraph operator and the other as the deciphering intelligence officer. The operator transmits 3-letter spelling words or vocabulary terms using the tap key. The receiver uses the branching map to decode the letters and write down the secret word.
Why is 'E' a single dot and 'T' a single dash, while 'Q' and 'Z' require four symbols? Have students analyze the English letter frequency distribution and compare it to the Morse code length hierarchy, discovering why efficient data compression requires shorter symbols for common characters.
Demonstrate the universal maritime distress signal SOS (••• ——— •••). Discuss its historical importance in maritime safety, radio navigation, and disaster rescue.
