Ever wanted to learn morse code quickly? Here's a small program I made to teach NATO morse code using mnemonics. Press any letter to learn, press space to practice. Instructions: The mnemonics sound like the tones - for example "C" is _ . _ . (Dah-Di-Dah-Dit) which also sounds like the syllables of "Coca Cola" - C for Coca Cola (Dah-Di-Dah-Dit) . Hope that makes sense. https://drive.google.com/file/d/... |

Morse Code trainers must be some of the oldest program concepts at all. Good to see somebody has ported it to modern graphics. But tell me, a 3 bit morse code (it's always 3 bit as I understand) can encode only 8 characters - how do they encode the alphabet? |
||||

I guess, technically, the 3 bits are: Dots/Dashes/Pauses - but not every letter uses all of them, so I would say it's more "binary" (dot/dash) or "variable bits" (as it doesn't have a universal number of bits-per-byte or bytes-per-word). The tempo is always the same (per conversation) but the letters are different lengths and each has a unique phonic signature (a combination 1, 2, 3 or 4 dots/dashes, followed by a pause). It was optimized to use the least number of possible clicks per letter/word. The pauses can also different lengths to denote punctuation. There are also abbreviations (slang) for most commonly used words - so you don't necessarily have to spell out every word completely to make a sentence. Military personnel can also use encrypted morse where the sender and receiver have a "look-up card" to decode the encryption. Here's a basic guide.... |

Ok, I see, thanks. So we have kind of 1 to 4 bit in parallel, that's 2+4+8+16= 30 potential letters. But then the pause is important. I assume no numbers? |
||||
|
You can spell out the letters for the numbers or use the 5 bit number-codes.... With practice, people can morse over 100 words per minute, but the average speed is slower. |
||||
|
In theory, the potential letters are infinite by adding more bits or using a look-up chart. Different Countries use different codes to suit their needs. You could, for example, use morse to send computer binary or Hex instead of a spoken language. This is the basic principle behind machine-code/modems/satellites/mobile-phones etc. but obviously machines are much quicker than humans - but I could send you a ccb file by morse if we had enough time, lol. |
||||

Ok I see. Yeah, we could swap CCB files with a spark plug and an FM radio. With like 2 bits per second. I actually thought about that, in case of a apocalypse where all phones and the web would be shut down, but then I would try sending binary ASCII right away. Except for when on sea. For that case I just saved the code image you provided, thanks ^^ When you only got a click in the ether, like from a spark, I guess I'd use single click and double click for short - long. |

Thanks veganpete, this is cool! |

Thanks andgameplay! You're welcome - glad you like it. Hope you find it useful. |

cps-games Haha, exactly. I think people do actually use it to send all sorts of stuff, such as images etc. (mainly for fun and competitions) but the potential is there for all sorts of real-life applications. Yes,if you have only a click in the aether, it would be much slower communication - but, rather than use double-clicks (which can be confusing), most people use longer pauses/spaces between the dashes and shorter pauses for the dots. There are no rules really, as long as the receiving person understands what you're sending - you can personalize and modify the rules to suit your own needs/situation. If you have a torch (even a mirror to reflect sunlight), you can send morse for miles silently. Ships often use their search beams to communicate with each other (they fit a shutter with a lever to manually block the light). Trapped Miners/Submariners etc have been known to communicate with tools banging on pipes or the hull or rock-beds etc. A great communication tool for emergencies. Some people even claim to communicate into space with High-Power LASERS - although not sure if they ever get a reply, lol. There's also short-wave radio broadcasts (which are known as "Number Stations") - they continuously send code for decades. It's often in morse code or just a stream of synthesised voice spoken numbers/letter to send encrypted morse. These are usually military broadcasts for secret service personnel in different countries - very slow and simple - but they have proven impossible to crack/decipher over the years. Finally there is semaphore - which is completely different close-range communication system between ground-crew, aircraft and ships - which uses batons (or even just your arms) to make words and letters using unique shapes and movement-gestures. |

Haha, thanks just_in_case! I always wanted to learn morse code. I bought an app from itchio but I thought I'd have a go at making this project in coppercube to share. Took around 3 hours to make. It's helped me to remember most of the letters. I'm not very quick yet, but it seems to be a lot easier to learn than I though it would be. |

Ah, it didn't post the ASCII symbol.... |
