I write science fiction, draw, paint, photobash, do woodworking, and dabble in 2d videogames design. Big fan of reducing waste, and of building community

  • Reticulum is a decent candidate for this (in that it’s purpose-built for more than texting).

    There’s a couple good beginner’s introductions here:

    https://www.carstenboll.dk/reticulum-a-beginners-guide/

    https://github.com/samuk/awesome-reticulum/

    Reticulum is a whole cryptography-based network stack which feels like it was developed from the ground up out of radio networking protocols. It can run over the same LoRa radio devices Meshtastic and Meshcore can use, but it can also use ad-hoc WiFi, data radios, modems, serial lines, amateur radio digital modes, and it can even tunnel through the Internet (meaning you could set up a local mesh of LoRa radios, old personal computers and laptops, and whatever wireless routers and other networking gear you can find, connect a neighborhood together using Reticulum as the underlying network, then connect that through the internet to Reticulum networks anywhere in the world. You can write software to run on Reticulum, and it already has a bunch of programs like NomadNet which can do encrypted messaging (same goal as Meshtastic and Meshcore) but also host and view text-based web pages and I think some other stuff. In a lot of ways, this one feels like the meshnet you’d see in a scifi book, an all-encrypted network stack that allows you to just link together any old hardware you can scrape together and rebuild a decentralized version of the internet grounded in much more secure protocols. (I’ll admit I straight up don’t understand how a lot of this works on the network/cryptography level, it actually seems similar to Tor in some ways but I don’t understand that very well either.)













  • I’ve got two-ish projects that might count: I’ve been reading up on Reticulum mesh networking, particularly with LoRa nodes. I like the idea of that kind of network, but have no idea what amount of activity I’ll find nearby despite living in a pretty big city. I’m still at the stage of figuring out what to get and how I’d like to use it.

    I’m also looking at setting up a Gemini server (the gopher-based web alternative protocol thing, not google’s dumb LLM) but I’m a bit skittish about anything that puts a hole into my home network, especially a service made by such a small group because I don’t know what kind of security holes might have been missed (I’m certainly not likely to spot them). Ideally I could set it up through Reticulum, so it’d be air gapped from my regular network, and it appears that someone has made that work, but I think it’d only be accessible to other folks on Reticulum and I’m not sure if that’d be worth it at first. We’ll see!

    My active project at the moment probably barely counts because I’m going full analog. I’ve got two antique Leich 901 crank telephones (like an actual crank, not a dial. Turning it generates AC and rings all the phones on the network).

    I plan to use them to rig an intercom between the kitchen and workshop. This’ll involve some woodworking as I’m making a nice box for the talk battery for one, and a display board with a voltmeter and two plexiglass-covered cutouts for displaying the wiring and batteries for the workshop end.

    I got them all wired up with some really ugly splices and was impressed - they can ring each other and the sound quality is quite good when talking, no repairs needed! Attaching them together is rock simple, just a few wires, plug and play. But my plan is to wire in some old rj11 phone jacks to the display board and battery box so they can (mis)use standard phone cables to talk to each other. In fact I’m hoping to use some of the old wiring already in place in my apartment.








  • Lore might be a good candidate - one narrator relaying stories from history that are dark or spooky in one way or another. It’s quite fun and well-produced.

    https://www.lorepodcast.com/

    Be warned that he approaches history from a folklore standpoint and will sort of tell you the spooky story version of what happened and how it impacts modern day pop culture - so if you compare one of his (fairly short) episodes on a well-docunented famous murder or something to a deep-dive series or book on the subject it will be missing information.
