Endless Mike posted:embedded windows 11 and everything is a UWP app imo Yeah but then you're using windows... If I had some time to learn and experiment I would want to try it with a pared down Linux-based OS. The OS would handle safety critical information output directly. I'm assuming there are some good libraries for interfacing with the CAN bus. The actual UI for safety critical info could probably reasonably be a C++ based Qt project, maybe some other F/OSS GUI framework. That info would be an always present top/bottom/side bar. Safety critical input should always have a separate, discrete, tactile input mechanism like a button or switch so maybe or maybe not include it in the touch screen. Everything else that could otherwise be considered fail-safe would go into its own separate process that's an abstraction level higher, so something like a .NET application or gently caress it even a JS webbrowser based solution, who cares. Set it up so the operator can trigger an infotainment system restart that leaves safety critical displays intact.

solar roof tiles seem like such a nightmare. It's like "we could install this thing with 10 interlocking parts and mostly isolate it from the other critical parts of your house...but what if we made it 1,500 interlocking parts and if it fails you're also suddenly homeless because you need some specialist to repair it instead of some dude with a hammer, some tar, and a blowtorch."

how do these roof tiles actually connect electrically to each other? do you actually need to run wires with connectors between each single tile? do they have some kind of snap on connector thing that make them snap to each other? how do you deal with weird roof shapes? it does seem really dumb and unnecessarily complex but i can see it being pushed here in switzerland where we have super strict building codes for the aesthetics of houses

Juul-Whip posted:don't solar panels need to be perpendicular to the sun's rays to work at max efficiency? meaning solar roof tiles work as well as a regular panel only if your home is at the same angle and roof slope you'd put the regular panel at if you want maximum efficiency you have to calculate the sun's apparent position for your location and date/time and continuously orient the solar panels towards it (this is a surprisingly tricky calculation in the general case, although you can get an estimate to within a fraction of a degree for the next few decades, which is good enough). roof solar panels are never going to achieve the maximum possible irradiance but you don't necessarily need that - especially in high latitudes the angle to the sun varies a lot throughout the year but static panels can still be worthwhile. longyearbyen airport (at 78°N) for instance has a useful solar installation even though the sun is below the horizon for five months straight every year

car infotainment should imo be on andoid tablets with stripped down firmware. include only what the infotainment poo poo needs. hook up to the car systems but only as a secondary source of input, use physical buttons and controls for poo poo like a/c, wipers, etc. the dashboard / instrument cluster should either be embedded-application single-purpose poo poo or more traditional displays for speed and important vehicle info (gas, etc). warning and indicator lights should always have a real bulb on the dashboard but a duplicate one on whatever the main display is fine. like if you show the tpms light and the dashboard screen shows "[tpms] check tire pressure: rear left 4.20psi" that's good. nothing critical should be reliant on poo poo more complicated design-wise than an 1984 NESThe_Franz posted:Can a drywall roof support solar panels? with the correct insulation, perhaps

i'm a page and a half late but 'solar roofs' are loving stupid and bad. When you get a hole or leak in your roof, you do not want to have to hunt down the guy who is both adept at tarring up leaks AND officially certified™ to work on your particular brand of solar roof tiles to avoid a warranty void or (in solarcity's case), loving Fire. when you have a problem with your solar panels, you want to get a technician out there who is an expert at solar panels. People that scream and howl about SoLaR pAnElS aRe uGlY > : ( are dumb and bad and wrong. That is all.

A well timed article given the recent infotainment architecture discussion: https://arstechnica.com/cars/2022/01/with-qualcomm-and-android-the-polestar-3-is-more-smartphone-like-than-ever/ With this particularly relevant quote about the instrument cluster integration: quote:But about the Gen 3's extra features: it has upgraded RF capabilities like Wi-Fi 6, 5G, and newer Bluetooth, which you couldn't get on the Snapdragon 820. Supporting a car, especially an Android car, also means needing support for virtualization. Android can run the infotainment system, but something else needs to run the gauge cluster display behind the steering wheel. Safety regulations mandate that the gauge cluster can't run Android. Android isn't a real-time OS, meaning it can lag if the processor is too slow, and that's not allowed for critical driving components like the speedometer. The solution is to have the Snapdragon 820 run two OSes via virtualization, with Android running the center infotainment screen and some other OS running the gauge cluster display. Android can still send the gauge cluster a UI overlay for things like media info and Google Maps information, but the speedo is off-limits. So at least in the Qualcomm/Google/Polestar configuration Android runs the center display while the instrument cluster runs a RTOS and can receive data from the Android side.

I know what they mean, but honestly it is kind of amusing to me that this speedometer is always the example they give of a critical instrument. It's like the least important instrument on your dashboard. I would put the oil pressure lamp or gauge, coolant temperature gauge, high beam indicator, turn signal indicator, and tachometer all ahead of a speedometer in importance.

the buffering circuits on things like coolant temp and oil pressure bother me. Like, don't lie to me "oh i'm carefully reading out the engine temp like a good little circuit and would ya look at that, i'm always dead center, except when the needle rises or drops, which means that your head gasket got blown or your bearings got spun 15 seconds ago". Just bring back the idiot light. my bmws were notorious for this. if the coolant needle moved up at all your system was full of steam or nothing already.

Apparently that's why cars don't come with ammeters these days, too, even if you have one fancy enough to still have electrical system gauges. Ammeters show the real time state of your electrical system, so they bounce all over the place when the car is starting, wiggle up and down in time with the windshield wipers, and rise and fall with engine speed. This is useful information -- and totally normal -- if you know what it means and are trying to keep an eye on how well your car's electrical system is performing, but apparently seeing the gauge move so much made less knowledgeable people angry because they thought the car was broken. A voltmeter, in comparison, really only tells you your battery's state of charge, which is not that useful. But in most cases the voltmeter just goes up to 14.8 when you start the car and stays there, and that makes people happy. So now all your fancy sports cars and bro trucks and whatnot have voltmeters, but no ammeters.

Yeah for sure. I am aware of the psychological reasoning behind the buffering and (astute observation) the lack of ammeters. the one in my old truck would yeet all over constantly. I still hate the poo poo out of it though.

I only discovered in the last 5 or so years that the warning lights are color coded. Red is bad, yellow/amber is get it checked at some point. Blinking of either means you're hosed. The thing is, no one tells you this, I think I learned it from a podcast or something.
