  • V2H unfortunately isn’t broadly available as a concept in the US yet.

    For what it’s worth, most of the Kia/Hyundai V2L plugged into your house shenanigans aren’t as convoluted as they might seem. Basically there’s something called a Transfer Switch that you can get installed into your house’s circuit breaker. It tells your house to stop pulling power from the grid, and start pulling it from whatever you have plugged into the switch. It’s technology that’s been around for ages for gas generators. You can hire an electrician to install it. The big issue with the current Kia/Hyundai V2L and transfer switch setup is 1) the car’s doesn’t put out enough voltage to power an HVAC system in certain power outage situations, and 2) You don’t any of the novel back and forth charging where your house / the grid can use your car like a cheap reserve. Folks have used Ioniq 5s to keep a fridge and some lights going for days though.

    At this point your options are be a Lightening early adopter, wait, or buy whichever electric car you’d like now and maybe look into a generator.


  • 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.









  • CARROT’s big premium selling point is letting you pick which weather data provider the app references. Darksky/Weatherkit went through a perceived slump after their acquisition, so folks turned to sites like https://www.forecastadvisor.com/ to figure out who was providing the most accurate data in their region.

    Other than that, it offers up a few more detailed views, push notifications, and other UI tweaks. They’re one of those companies that tries jumping onboard with things like Apple Watch apps or home screen widgets ASAP.

    You probably don’t need CARROT, but if you don’t like the stock Weather app, CARROT probably has something for you.

    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.
