WIRELESS Messaging in Minecraft 1.17
In this Minecraft Snapshot 20W49A Minecraft Snapshot video, Mumbo makes use of the New Minecraft sculk sensors coming in Minecraft 1.17, the Minecraft: Cave and Cliffs update that was announced at Minecon Live 2020. This wireless redstone messaging system allows you to encode and decode messages over a wireless redstone line that spans hundreds of blocks. VERY VERY COOL!

    Anyone who says 'just use chat' is not my friend, and if we were on the same server I would make sure my wireless messaging system went to everyone but you.

      Now you just need a multi-user version with send/receive identifiers for the sake of your network. Enjoy Mumbo.

      is it possible to send a signal of a certain strength? for example, instead of using a counter you built a redstone contraption that triggers different sounds or actions, which in turn send out a signal with different strengths for an instant messaging system?

    I'd love to build this but with 5 bit instead of 1 bit of information. Then you could actually use the alphabet.

    Is it possible to use items with letters as name and send a Code that the other Maschine drop them in a chest in the same Order. It will take long to send but it could be any sentence

    Here is a hypothetical question: what if mojang cancelled the caves and cliffs update...? That scream you heard was Mumbo Jumbo. (And me.) (And the rest of the minecraft community, especially the redstone community.)

  • McClaps

    @Mumbo Jumbo Have you tried sending a message from a few hundred chunks or anything close to that to know the limit of the machine

    For the long distance communication... The current receiver in the other end could activate different dispensers instead of lamps which shoot different items (different skulk strenths). Each dispenser has a river which meets to create a unified river (or railways with hoopers) leading to a nether portal. The dispenser chosen shoots its item to the river which flows to a nether portal. Then there would be a TNT-enderpearl machine. When it gets there, the item (instead of ender pearls) are lauched into the distance to another portal sending the item back to overworld on a farther distance from the starting point. Then thats where the other message-receiver can be placed to detect the signal strength and translate it to a readable message.

    Could you not speed that signal transmission up using more wireless towers? The receiving/sending mechanism would quickly get very big and complicated but I think it's possibe? Also For those who say "just use chat" what if it's a secret message? ...("just use discord") SHUT UP! The implications of this are amazing by the way, If you wanted to allow for multiple destinations for your message you would need to send a single at the beginning of your message to tell your hub (which splits off into several directions) were to rout your message. This is literally encapsulation of information on the internet. Now thanks to Mumbo people can start to teach the basics of networking using Redstone. Mine you, it would be really hard and not at all worth it but still! I can see it now, massive hubs serving as routers and switches, directing messages to different locations, using Redstone! So pointless, but so cool!

    Counting up one at a time isn’t a very efficient method. Using binary is much better because the amount of possible things you can send increases exponentially with how many bits (pulses / pauses in this case) you have. 4 bits can have 16 different combinations so if you wanted to send message 13 for example you would do PULSE PULSE PAUSE PULSE (1101=13). Or you could do 5 bits for 32 characters and be able to send the alphabet. It would still be slower than preset messages but much faster then having to count all the way up to 26 in a worst case scenario.

  • lifeinsepia

    you should binary encode the messages rather than sending a variable number of pulses. you can get 256 different messages with only 8 pulses this way, or your 15 message system can be encoded with only 4 pulses!

    Sadly this doesn'tn't work across long distances. The entire data line would need to stay loaded during transmission. You would need a chunk loader.
