Kaiser Schnitzel posted:‘Wetordry’ is a brand name for a type of wet sandpaper made by 3M. Thanks! I've basically got a 1200 grit cutting disc based on some sort of resin material for gemcutting. The instructions say I need to burnish it with 400 grit wet or dry (I guess wet is the same then) sandpaper before use. Getting some 400 grit grains stuck in the cutting surface would really suck, the seller seemed confident that the right sandpaper should not have that issue though

Hey gang, this isn't so important that it actually needs an answer, but I'm curious as to what someone might be able to discern from this problem I'm having using Hulu on my Galaxy s10e. The problem is this: when I use Hulu at home on my wifi on this phone, Hulu will play the movie for about three minutes and then it will halt. After a spinning circle rotates enough times, Hulu tells me "We're having trouble playing this right now..." From there, I can navigate Hulu, but no movies will play. Once I close the program, it will not open again. I have to reset the phone to make it work. So the thing about all this is that this only happens on my wifi at home. I can use Hulu anywhere else no problem, and I can use the wifi at home with no problem. I can use any other program on my wifi with no problem. This is very specifically just Hulu, and only after about three minutes of playing a movie (I haven't actually timed it, but it's consistent.) Like I said, this doesn't really need a solution. Restarting the phone doesn't take much time. But I can't imagine what is causing this very specific problem to happen under these very specific circumstances.

red seems like one of the more common options for a lot of cars. not as common on the street as black, gray, blue, or white, but still pretty common. more rare colors these days are yellow, purple, pink, orange, brown, and many shades of green. of course these trends shift over time, there were a lot more green and brown cars in the 70's than there are now (and even some common yellow ones), and the grays and muted blues that are common today were less popular then

yea thats true certain very expensive sports cars come in bright yellow i was thinking more of the range of creamy yellow to light beige that was more common on all kinds of cars in the 70's and 80's     used to see it on the street all the time but its not a color thats been common on new models in the same categories for like 30 years now

Any advice when it comes to mounting a TV over a fireplace? The legs on our TV are too wide for the mantle and even if they weren't we don't want to crane our necks upward to watch TV. I found some mounts online that pull out and down. As far as installing them goes, anything I need to look out for? The nearest outlet is in the corner and I'd like to hide the wires too. We've got speakers, a subwoofer, a switch, and a blu-ray player. I'd like to put the speakers on small shelves so they're also off the floor.

So my wife and I just bought a house with a TV mounted above the fireplace with wires hidden in the wall. It seems like hiding the wires in the wall was such a pain in the rear end to do, they installed 2 hdmi cables so that if one breaks, they never had to do it again. The previous owner left them both where they were. Sorry I don't have any experience actually doing the install.

Slimy Hog posted:Why would you want your TV so high? It's a small place and there's nowhere else that a TV and a couch would really fit. There are mounts that allow you to pull a TV down to eye level when it's being used so that's what we're gonna use. Right now, it's just sitting on the floor in front of the fireplace and I want it off the floor. It's a gas fireplace and the wall is drywall.

There are braille displays with lots of little rods so the user can move their finger across them and control reading speed, etc. But has there been something you wear on your hand and finger that uses haptic technology (or six tiny rods?) to simulate one of those displays using motion tracking or similar? Like if a video game controller can detect precise position in space, why can't we make a virtual braille display by tracking the finger? I imagine maybe it's too expensive or too heavy on the finger to get six points felt precisely, or maybe there's a speed limitation in that you can't change what the finger feels nearly fast enough, etc. I searched for "haptic braille" and found three different products/prototypes that all were almost entirely different from this so even just the right keyword(s) would be helpful.

I imagine maybe it's too expensive or too heavy on the finger to get six points felt precisely, or maybe there's a speed limitation in that you can't change what the finger feels nearly fast enough, etc. It’s an interesting idea. The closest I could find was the DOT smart watch, and it’s not close at all. The form factor could work, and it has one or more accelerometers in it, but in demos it certainly does not behave like you are describing. I think there is a good reason for that. Blind people depend on the feel of the the bumps sliding under their fingers as they move along a line of text. It would not due to simply push the pins up and down under a stationary finger. I also don’t think it would be enough to have a high-resolution pin grid in the left–right axis and have the pins rise and fall like waves. I think the sliding friction is important, but I’ve never used braille, so I could be wrong and it would not be so hard to get used to. Assuming that sliding friction is important, we’re looking at some kind of belt or drum system with pins moving within it. Think of a music box or a player piano that can change tune on-the-fly That sounds like an interesting mechanical challenge, but it’s just that: a challenge, and if it were solved, it wouldn’t necessarily result in a successful device.

I read an article once about putting a "display" on the tongue which was good enough to allow blinded people to navigate around basic obstacles. The problem with fingers is that they're too small to fit enough pixels in for a useful display. The tongue is larger and also sensitive enough.

I think there's probably been less innovation in braille technology then there otherwise would have been since screen readers (including those on cell phones) really exploded in usefulness/popularity. That does sound like a dope idea though.

This fairly non-tendentious blogpost sums it up. Anecdotally, I have a friend who is very invested in using different water temperatures for different beans/roasts, which I doubt even a fancy drip coffeemaker offers as an option.

Manager Hoyden posted:What's the functional difference between making pour over coffee and using a plain old drip coffee maker? Mechanically the action seems identical. As someone who buys expensive beans for his pour over, they're pretty similar, but you get more control over timing and distribution manually. And the technique requires different pouring speeds depending on amount of coffee and what step in the pouring you're on. I think you could probably engineer a machine to do it right, but nerds like me wouldn't buy it anyway, and no one else would either because it would be a lot more expensive.

Just an earbud sticking out of his pocket was like the whole phone experience for him. It almost made me want to learn how the accessibility stuff works so I could do the same.

Why does wind vary in speeds, like gusts and stuff? If you stand near a riverbank all the water will flow at the same rate from the point of where you are, but something like wind will blow at different speeds.Why isn’t it constant? I don’t understand it.

All the water in a river does not flow at the same rate, laminar flow will be slower at the sides and near the bottom, and turbulent flow will have dozens of different directions for different parts of the water to be moving at any time. The same is true for wind, because wind is also a fluid. It's a very large scale function of the temperatures and air parcels and poo poo that are all around you, and it's also being dragged by friction in different directions and poo poo as it moves.

I don’t understand it. Take some heart in the fact that the physics of fluids is extremely complicated and expensive to simulate. Weather is fundamentally chaotic, meaning that a small change in the system can have drastic changes in observed behaviors later on in time.

hey follow up to the garage issue, i got the knob removed and replaced with a deadbolt, so yay! now the issue is the electrical in there, I'm getting 60 volts on the voltmeter instead of 120, and I don't know much about electricity but I know that's not right. the wiring in there looks pretty slap dash so it's probably hosed up somewhere, right? edit: gently caress wrong thread erosion fucked around with this message at 04:37 on Mar 20, 2021 |

Is it normal to start to get headaches while studying, after a long time of not? I'm starting to buckle down on my studies today with the aim of doing a couple of hours today (my usual being a couple of hours over a week or two). But I'm about an hour into it and I'm starting to get a pretty bad headache. Is this like, the brain not being used to working so much in such a short space of time, meaning I need to slowly build up to extended times. Or is it psychosomatic and I just need to force my way through it? I'm not one to suffer from headaches usually so while this might just be poor timing, its unlikely.
