  • I can’t help much on the power draw side of this question, but one thing to look out for with a UPS is some sort of communication option. (Usually NUT over ethernet, but there are some USB options too.) Most modern UPS brands will have a plugin you can install on your Raspberry Pi and Mini PC that allows your UPS to signal, “Hey, I’ve got 3% of battery life, you actually need to gracefully shut down now.” It’s mostly useful for NAS applications with spinning drives, but it could help save your Pi’s SD card potentially.

    It’s a pretty standard feature these days, but the cheapest of the cheap will omit it.

    Modern satellites are protected by various means of encryption, but there’s an enthusiast community that tracks down and communicates with very old unencrypted zombie satellites. There’s even been an NGO which managed to fire rockets on an abandoned NASA/ESA probe (with their approval.)

    The Voyagers benefits primarily from the lack of groups with an adequate deep space network to communicate with it. Their communication standards are otherwise completely open and well documented.

    I still cannot believe NASA managed to re-establish a connection with Voyager 1.

    That scene from The Martian where JPL had a hardware copy of Pathfinder on Earth? That’s not apocryphal. NASA keeps a lot of engineering models around for a variety of purposes including this sort of hardware troubleshooting.

    It’s a practice they started after Voyager. They shot that patch off into space based off of old documentation, blueprints, and internal memos.

    Chicken tortilla soup with a healthy dose of lime! My local taco place does a soup special when it gets cold, and I’ve had this one enough that I wanted to try and recreate it. I usually skew more towards stews in chilly weather, but this soup’s on my short list next time I’m in the mood for something brothy.



  • It sounds like there might not be much in your stew to thicken it. The beef fat helps a bit, but you can toss the beef chunks in flour to give the stew a bit more body. This recipe I used just straight up has you add some unflavored powdered gelatin to it to give you that coating-the-back-of-a-spoon texture.

    I’ve used red wine and beef in dishes together in the past. Usually you just need something a little salty to balance the sweetness out. The UK condiment marmite usually does the trick for me, although soy sauce can work in a pinch.





  • There’s a whole linage of arcade game button design, but you occasionally see keyboard switches show up in custom fighting game sticks.

    Mice and trackballs often borrow from the whole universe of buttons to make their sculpted formfactors work. I feel like I’ve seen one or two with mechanical keyboard switches in them.

    Like rockSlayer mentioned, they just bridge a physical connection between two pins and can technically be used anywhere a typical button could be. Keyboard switches are so optimized for their large square footprint and particular travel distance that they’re usually not the best fit for random industrial needs. You could make an elevator control panel out of key switches, but there’s probably a cheaper, more well suited button you could use instead.
