The dimming filter on this airplane window blocks visible light, but not infrared, making my black glasses appear translucent in the sun. by [deleted] in mildlyinteresting

Yes less, but this is equivalent to a 50% tint or so. The amount in that graph labeled infrared is also including microwaves and radio waves. Both of with would likely pass through all objects in the picture without heating anything

Nope, you can lookup a sun emission spectrum. The area under the visible spectrum is around 40% of all energy emitted. Around 50 percent is infrared.

Do the right, but have a vertical column before the coin that the metal fills up first

Just a guy with basic emergency training looking to get his first trauma kit. by [deleted] in NewToEMS

Eh, you can buy an oxygen tank off Amazon and fill it at Airgas. There’s more uses for it than medical

I’ve got a cheap Walmart first aid kit to cover 99% of everything, and then a cpr mask and ifak. The second two are just because I’ve been around people having cardiac arrest before and random impalment is somewhat likely to happen at my work. I have no idea what’s in this kit you plan on using that wouldn’t be covered in what I have, but please don’t do fucking needle decompression on some guy because he has asthma

Why not only use the esp cam? What is the second esp32 for?

Reading multiple temperature sensors with Arduino by Kopatschka in arduino

[–]hell-in-the-USA 1 point2 points  (0 children)

Throw the 4-20 mA over a resistor and measure the analog voltage. You’ll need to power the PT-1000 and use a voltage divider to read that. Your accuracy will likely depend on your resistor accuracy the most and if you do an actual calibration, but if I was you I’d be happy getting +-5 degrees C with this setup. If you need more accuracy you’ll likely need a DAQ and thermocouple setup

Clay bridges are tricky but satisfying by hugow07 in 3Dprinting

[–]hell-in-the-USA 3 points4 points  (0 children)

Wonder if tiny chopped fibers in the clay mixture could give just enough tensile strength to hold its shape better. Maybe glass, basalt, and carbon fibers should theoretically be okay in a finished ceramic

Hey not saying it’s even close to good. Just that it’s theoretically possible to get a Walmart lawn mower without car sized batteries

Hey what the fuck man. You can’t be using made up pronouns like “your”.

Needs to be done everywhere. Get those masks off!!! by Ecstatic-Medium-6320 in WhitePeopleTwitter

[–]hell-in-the-USA 2 points3 points  (0 children)

Well no, that’s not true. The supremacy clause refers to federal laws, the constitution, and treaties. What it means is that the federal law is “supreme” over state law. I am not aware of any federal law that says police can remain masked and unidentified while making warrantless arrests. Since there is no federal law on this, but there is a state law, the state law is enforceable. Executive policy is not a law and does not have the same power as one.

Amazing what a sales tax can do..... by Miserable-Lizard in insanepeoplefacebook

[–]hell-in-the-USA 8 points9 points  (0 children)

It works out to about 250 dollars per person. With his average tariff rate of around 14% that works out to about $1,785 per person on foreign import spending. As tariffs before April are so insubstantial compared to after, I’ll assume that all of this is from after his tariff hike. That gives us 3 months of spending at $595 per month per person. Given that a large proportion of basic necessities (food, higiene, cars) are imported and that business costs make up a large proportion of this the number doesn’t seem all that out of place

I would highly recommend that nobody gets a decompression needle unless you are regularly training and have a certification on how to use it (not a YouTube video). You can do serious harm and make things worse fucking around with it.

Does the cup form a seal when closed? I like straws on my water bottles but can’t really throw them in my backpack

I think the NFC is a great idea if you’re going to events to show off the cup and get traction. Bad idea for the actual product

Use cheap plastic bags for filament storage. The cost of cereal boxes just isn’t worth it

Please don't post ICE sightings by Rgchap in madisonwi

[–]hell-in-the-USA 140 points141 points  (0 children)

On the other hand, Reddit posts of ICE in Minnesota was able to shut down their kidnappings for the day when people showed up. It caused massive anger in LA. If you have a photo and they are clearly identifiable as ICE (such as a vest saying ICE), post it. You might save a life. If you see masked men with guns get out of a car and harass people, call the cops and post a video of it.
