I don't imagine many folks in the Fediverse crowd will learn much here, but I've got a new video to show your boomer parents https://www.youtube.com/watch?v=0KoeY54M5VA

this video will blow you away https://www.youtube.com/watch?v=_KWdCqpXB7A

i made this https://www.youtube.com/watch?v=KnUFH5GX_fI

ding-dong, gotta new video out today https://www.youtube.com/watch?v=nXdVG45wveo

Now, people browsing YouTube looking for something to watch are getting a helpful video with a thumbnail and title that makes clear "this is a door closer, they are adjustable, I will show you how to slow them down" and they're going to learn a lot of cool shit if they click through. That's why I do this. And please feel free to bookmark this thread in case you'd like to educate one of the loud YouTube/video haters for me.

So next time someone shares a YouTube video with you and you want to be a stick in the mud about that, remember that everyone has their own paths to knowledge *and* their own way to spread knowledge. "this could have been an article" Yeah it could be, and in fact it is! Anyone could look up door closers on Wikipedia and get the gist of my video's information. But many millions of people don't even know they're called door closers. Hell, I didn't! Not until I needed to install one.

@sbrudenell In this case, it's genuinely because I think about energy a lot and what consumes it in what processes. Understanding the inefficiencies of things helps identify opportunities. Then when you look at what engineers are doing to leverage those opportunities, you can piece together the details.

To explain, this is my car's (Hyundai Ioniq 5) vehicle-to-load function in action. A simple adapter signals the car to backfeed AC voltage from an inverter to the charge port (This is a generic adapter, btw, teardowns of the official unit reveal it's basically just a resistor across the control pins). This adapter turns the car into a generator capable of running basic necessities for days. You have the full 15A of any outlet at your disposal. Pretty neat™

@electropict Given the cars you've just mentioned, remember that the US gallon is smaller than an Imperial gallon by a pretty large margin.

@pepper It helps a lot and I would encourage using it, but just buy the cheap stuff. All it is is a mild surfactant.

@Malfunct This is not positioned as a value product, which put me in a bit of an awkward spot but I am happy to have proven powders can be excellent. Your question about dosing? The great thing about powder is there are no rules. I would probably try using just two teaspoons in the main wash, and add a third teaspoon for the pre-wash when you have greasy/oily stuff in the dishwasher.

@mdwyer I say this because it rings to me like "the library's not doing a good job putting a bookcase together just for me each time I walk in" and like... is that the library's job? My algorithms video is much less about how bad algorithms have gotten and much more about how strange it is that we seem to expect the world to work like this now.

@GottaLaff @jztusk @mastodonmigration @Teri_Kanefield @Popehat @mmasnick @mattblaze people say that, but I had an easier time on the bird site with about three times as many followers than I do here. At this point I think the sorts of harassment that popular accounts experience are just impossible to sympathize with for most folks. Is that bad? No. I think it's hard for us to communicate the things that are bothering us. But the lack of caring is... well I don't think it's very nice!

@bondolo@mastodon.social Heh, funny you should mention this. I've written quite the gag intro for a related topic which I'll probably hammer out next.

@gadgetgav The reason they're normally not wired this way is because in the cooling season, the air handler gets a fan call when air conditioning. So if you have the humidifier connected to the G terminal, it can run at the same time as the air conditioner unless you remember to turn the humidifier off at the control.

@gadgetgav But what you might also be experiencing is what I was - with an oversized heating system, the heat doesn't run enough for the humidifier to do its job. I had previously fixed that issue with something of a hack but what I did in this video fixes it more properly.

@lambda@chaosfurs.social Every E-GMP platform car comes with this ability from what I gather, regardless of whether they have an outlet on the interior or not. Mine does also have that outlet (and it uses the same invertor), but a key part of this feature is that the car stays "asleep" so you don't have all the other accessory loads competing for energy.

@kwahoo Did you miss the part of the video where I show the computer commanding equivalence ratios above and below 1? The computer is deliberately causing those oscillations and we can see it in the scan tool.

@lambda@chaosfurs.social @agocs@hachyderm.io I suspect it's part of the on-board charger and not the traction motor inverter. That would certainly be the simplest way to make this happen since that's where the wires from the charge port actually go.

@FifiSch@mastodon.social I feel seen, thank you.

@skaverat Hmm, that's an interesting angle. I also have had that problem with powder laundry detergent when using an old-fashioned top loader. I did eventually realize it was best to start it filling before loading clothes, but some modern machines don't let you do that anymore. However, now I've got a front loader with a detergent tray and I've been using powder with zero issues at all. My only issue with powder is that the boxes are impossible to open without making a mess!

@skaverat It just smells way too much like the detergent manufacturers discovering a way to make more money by A) preventing people from stretching their detergent and B) inventing marketing gimmicks which make people believe their products are magic.

@wizputer@hachyderm.io Well... probably not. The car can do that in markets where that's the normal line voltage, but those cars have the Type 2 connector. Perhaps it's just a different resistor value to signal 230 rather than 120, but I would bet Hyundai felt that too risky and NA market cars can only do 120

@RyDawg@mstdn.ca To be a whole-home backup, you need a way to recreate split-phase 240. The charge port can't do that (it can only send either 120 or 240) so to provide that particular functionality, you would indeed need an offboard inverter and in that case you might as well give it access to the battery pack's DC. In theory, though, this could provide 48A at 120V which would make it quite a capable generator. It just won't be able to power any big stuff like central air.

@penguin42@mastodon.org.uk The car won't open the charge door unless it's unlocked. Also, when this is in-use it becomes locked to the car and will stay so if the car is locked.

@deetlebee@disabled.social Power outages and/or camping

@danbrotherston@types.pl All of Hyundai/Kia's E-GMP platform cars can! It's a neat feature they built-in.

@danbrotherston@types.pl That's the reason this feature is standard on E-GMP platform cars. The charger just needs to be able to send power both ways. What's optional is in fact a second household outlet inside the car. It uses the same inverter, but now needs a new run of wiring. If you ask me, this is the most straightforward way to go about it. The adapter is literally just J1772 to NEMA 5-15 with a resistor between the signal pins to tell the car it's there and to send voltage to it.

@Suran@vulpine.club @lambda@chaosfurs.social It doesn't. And it can't. This is V2L, not V2G - so it's just meant as a temporary thing. Models sold in 230V markets sent 230V out for this feature, but there's no way for it to be dual-voltage here as far as I know. Feels like a recipe to fry things so I imagine it's configured to only output 120V in NA market cars.

@skaverat Pods are popular but I'd say they only have about 50% penetration. It's super easy to get pods, liquids, or powders in most stores.

@danbrotherston@types.pl Simple - this is outside the car and doesn't require the car to be powered on to work. Means the car can be off and locked, but still useful as a portable power source. And, there are already wires which carry AC power going between the weatherproof charge port and onboard charger. Why /not/ reuse them?

@stephen@mastodon.nz In a world where J3400 also exists, I suspect it will remain very much commercial. However, part of the J3400 standard includes moving to a more European-like system for public charging where you are expected to carry your own whip - with the Type 2 connector on one end and whatever your car takes on the other. That might fix the compatibility problem between various EVs and various connectors in a really elegant way.

@kwahoo If I had a car with a narrowband upstream sensor, I would have written how even an analog control circuit could enrich fuel when O2 sensor signal shows lean, and once it was enriched enough for the O2 sensor to switch, it could pull fuel back. It would be attempting to stay at 1.0 but hysteresis and lag would cause it to oscillate. A wideband sensor, though it still has a Nernst cell at its heart, is precise enough for the computer to be proactive rather than reactive.
