Show HN: I Built a Telegraph Simulator
- leugim 2y agoI was reading "The Victorian Internet" by Tom Standage and decide to build a proof of concept of an online telegraph.
- pj_mukh 2y agoThis is so cool. Knowing nothing about Telegraph standards are there no explicit signals for symbols or spaces?

- jdietrich 2y agoITU Morse does specify punctuation marks and a few symbols, but they're rarely used in practice. A space is denoted by a gap equal to seven dots. https://www.itu.int/dms_pubrec/itu-r/rec/m/R-REC-M.1677-1-200910-I!!PDF-E.pdf https://www.itu.int/dms_pubrec/itu-r/rec/m/R-REC-M.1677-1-20...

- troymc 2y agoI was rather hoping that a "Telegraph Simulator" simulated the electric and magnetic fields along a telegraph line. This is more of a Morse Code toy.
- Carrok 2y agoStill very cool.
- cadr 2y agoHow are you doing the timing for space? It feels off when I'm sending quickly, but also I never use a straight key, so my sending is probably terrible :)
- hagbard_c 2y agoIt is remarkable to see how shitposting is not a recent invention but seems to have been around in the Victorian age if the transmit logs on this thing are anything to go by.
- ale42 2y agoFunny idea... but it's way too slow to react. (saying this as ham radio operator doing CW, so pretty biased, but I guess actual telegraph operators were much faster than I am...)
- graypegg 2y agoMaybe a stupid solution to that, but it would be cool if each city+location also had a callsign shown next to their messages, and would get highlighted on their screen if you include it. That way you can at least get their attention after the minute or two it takes me to rattle off a message haha
- tdeck 2y agoIt seems to only recognize symbols when sent at the exact rate that it expects, which is extremely slow. That wouldn't be much of an issue except that the actual signal is lost, so the only way to communicate is through the site's interpretation of the dits and dahs.
- ge96 2y agoSOS Save Our Socket
- op00to 2y agoI see this over and over: "I HAVE HIJACKED THE SERVERS WEBSOCKET TO SEND CUSTOM MESSAGES IF YOU WANT TO DO THE SAME SEE THE FOLLOWING LINK [...]"
- firtoz 2y agoNote to self: when doing HN demos, bulletproof your endpoints
- anonyonoor 2y agoI followed the link and surprisingly, instead of a scam, it was actually an explanation of how to send custom web socket messages. https://rentry.co/MG5TR43 https://rentry.co/MG5TR43
- op00to 2y agoBraver than me!
- coldfoundry 2y agoYeah, there was no hijacking of a server-side websocket at all, just sending client socket messages to the server since there is no auth or ratelimiting. Sucks thats it’s so frequent, ruins the experience. You can essentially do this to any websocket you’re connected to.
- dakr 2y agoJudging by the comments I've seen go by the on the ticker, this is less a telegraph simulation than an observational experiment in how terrible people can be. It's a real shame.
- yapyap 2y agoSome fool is spamming
- tillcarlos 2y agoJust reading “seveneves” (newl stephensom) - so this comes in handy!
- sciens3_ 2y agoThis electricity nonsense is just a fad. The future will be powered by steam.

- sam345 2y agoSo much fun.
- willwade 2y agoNice. If you want to learn Morse try https://morse-learn.acecentre.net/ https://morse-learn.acecentre.net/ (I must throw cursor at this to fix some issues like working nicely on mobile).
- xvokcarts 2y agoYeah, what a fun way to spend some time :)
- CorpOverreach 2y agoIt's down! :(
- leugim 2y agoIt went down but working now
- popcar2 2y agoThat is wild, I recently updated my own Morse Code teaching tool to v2.0 yesterday, and it's somewhat similar in concept to this: https://popcar2.itch.io/morse-code-simulator https://popcar2.itch.io/morse-code-simulator Being able to transmit your signals to other people here is really cool. Makes it a lot more than just typing to yourself.
- bigbuppo 2y agoNeat, but not nearly responsive enough. When I was your age, we had to key at 5000 wpm or they wouldn't even let us look at a radio.
