Some glow in the dark chemicals are called phosphors, and while they’re named after phosphorus, they usually do not contain any phosphorus, zinc sulfide for example. These are the kinds of things you might find on a watch face or stickers or whatever that need to absorb light from some other source first.

To make it even more confusing, phosphorus isn’t actually phosphorescent, its glow is from chemiluminescence, the result of a chemical reaction.

And for what it’s worth, stuff that glows under a black light is fluorescent.

I don’t think phosphorus has ever been used for glowing tattoos, and if it was I’m pretty sure no one is still using it. We’re well outside of my realm of expertise, but it should also be considered that how a chemical enters your body can make a difference in how toxic it is too, there’s a whole lot of chemistry at work in your body, and ingesting something and absorbing it through digestion isn’t necessarily going to have the same effect as absorbing it through your skin, there’s a reason different medications have to be taken oral, allowed to dissolve under your tongue, given as a suppository, intravenously, intramuscularly, subdermally, etc. that said, I’m pretty sure phosphorus is bad no matter how you put it into someone’s body.

Looking down on clouds is a pretty surreal experience

I once went on a backpacking trip, our itinerary had us camping near the top of a mountain, just a little shy of 12,000ft and we knew there would be no potable water at the top, so we had our hot meal for the day at lunch since freeze dried backpacking food needs water, so we could refill and get through the next day.

As we’re making our way up the mountain, a thick fog rolls in. By the time we get to camp, we’re all pretty miserable, we’re tired and starting to feel the altitude a little, everything is cold and damp, we have a dinner of jerky and trail mix and such, we set up our tents and go the fuck to sleep.

The next day we wake up, the fog has gone, and it’s a beautiful day. We make our way to the top of the mountain and look down at the valley below and we see a cloud.

It then dawned on us that the fog the night before wasn’t just fog, it was a cloud we hiked through and set up camp in.

The next time a mattress salesman tries to give you the “it’s like sleeping on a cloud” line, fucking run, clouds suck.

If you take up the project and decide to make my dream your reality, all I ask is that you share the code

I haven’t done a deep dive into how I’m going to make it happen, my programming is rusty as all hell, and I’ve never tinkered too much with a pie or this kind of project

But on its surface it seems like an easy enough problem, just need to turn on the appropriate lights when an emulator starts.

Easier said than done I’m sure, I also suspect you’d probably need some kind of led controller or maybe an Arduino or something between the pie and the lights, I don’t think the 3.3v it puts out from its GPIO pins would be enough for some light strips.

If someone had a lot of money to throw at the project, I imagine you could also do a pretty cool setup with smart lights like Philips Hue that would be pretty clean and require minimal tinkering with the physical electronics side of things, but you’d probably be throwing as much or more at it in bulbs as the rest of the project put together.

Yeah, I like to bring it up and put the idea out into the world whenever I get an opportunity because part of me is kind of hoping that maybe someone out there will do the hard work and write the code and share it online so someday when I have the space for it all I have to do is wire up the lights

Also when it comes time to fill in the gaps in my collection, I can save some money and still get the same effect because the console doesn’t even have to be in working order, it just has to not be too beat-up looking. I could probably even 3d print some dummy consoles to hold me over (though of course I’d prefer to have actual working consoles if possible)

A dream project for me, when I have the space for it, is to have a set of Ikea kallax shelves with a cubby for each retro console with some LEDs inside hooked up to a retropie emulating those consoles so those cubbies light up when that console is being emulated.

I have a lot of the actual consoles and they’re in working order, but it’s a bit of a pain in the ass to get them hooked up, swap cartridges, etc. sometimes. And I have just enough programming and electronics background that I feel up to the task of trying to make it work, just don’t have the space for a big display shelf at the moment.

I can appreciate the experience of playing on the actual hardware and the cases where it’s superior, but for me the experience emulating them is 99% as good with significantly less effort. Totally cool if others prioritize things differently though.

His formatting leaves a bit to be desired, but that basically boils down to

1. Knives with certain features like a double edge, a handguard, butterfly knives and certain other one-handed opening mechanisms (I assume switchblades, maybe assisted openers, possibly gravity and flick knives) are weapons and can be owned but generally not carried

Otherwise…

2. Knives (and I assume this applies to other bladed tools as well since he mentioned an axe)with a blade length of less than about 5.5 inches are ok to carry for no particular reason, as long as either the blade doesn’t lock or it needs two hands to open it (from how he wrote it sounds to me like one or the other of those features is ok, but not both)

3. You can carry a bigger knife if you have a good reason that you need one, like if you’re going campings/hunting, or clearing brush with a machete (and from how he phrased it sounds like you could also carry a one-handed locking knife with a good reason)

4. You get carded to prove you’re an adult if you want to buy a sword (I assume knives as well)

Which is pretty straightforward, and actually similar to a lot of laws in the states (looser than some states I believe, and stricter than others)

Not really relevant to the comment you replied to and only tangentially related to some other comments in this thread. We’re talking about knives and soda caps here.

A lot of us don’t think of our knives as weapons, they’re tools.

It’s rare that I don’t carry a knife, and using it in self defense is the furthest thing from my mind every day when I put it in my pocket. I use it for things like opening packages, cutting string, sharpening pencils, use various other tools on the knife like screwdrivers, pliers, awls, I have a lot of outdoor hobbies like camping, hiking, fishing, and knives are kind of indispensable for those pursuits.

If I’m ever in a situation where I absolutely need to defend myself, and I don’t really foresee that ever being necessary, I’m probably not even going to think of using my knife in self defense, I don’t think of it as a weapon anymore than I think of my wallet being a weapon, it’s just something that lives in my pocket that I frequently need to use.

And knives make a shitty weapon, if you’re close enough to stab someone, you’re close enough to get punched in the face, or for your assailant to wrestle it out of your hands and stab you with it. You’d be better swinging around pretty much any larger object within arms reach to create some space. They say about knife fights that the loser dies in the street, the winner dies in the ambulance.

The knives I tend to carry especially aren’t good weapons, most need 2 hands to open, aren’t really designed ergonomically as fighting knives, most are fairly small so I’d have to get really lucky to hit anything vital and would probably just piss them off more and not stop the attack quickly, some of them don’t even have a pointy blade so not good for stabbing (I actually make it a point to choose less threatening looking knives for my EDC needs) some of them don’t lock open so they’d just as like close on my fingers as cause any harm to my assailant, and some of them actually lock in the closed position so definitely not good for a weapon.

I’m not saying that everyone who carries a knife has the same mindset. Lots of people do carry them as weapons, those people are idiots. And not everyone puts the same thought into the knives they carry and just get something that looks cool whether or not it’s functional for their needs.

I also don’t carry anything for self defense regularly and don’t own a gun (not opposed to gun ownership in general, but my thoughts on that are part whole 'nother debate,) in general if I feel like I need to be prepared to defend myself if I go somewhere, I just don’t go there. There’s a bit of privilege to that, since I live in a safe area and can make that call, not everyone is lucky enough to live somewhere they can feel safe. The only exception is the pepper spray I keep with my dogs leash, since my wife or I often end up walking her alone at night, and that’s more of a precaution against loose dogs, coyotes, etc. than against people.

There’s a lot to say about Americans’ love of violence and weapons and the sort of mindset we have about self defense, and overall I tend to think that a lot of my country is absolutely insane when it comes to those matters. That said, I also think people who look at the little swiss army type knives, or Leatherman multitools I tend to carry and see a terrifying deadly weapon have their own issues to work out too.

AFAIK, these tethered caps are mostly an EU thing (and at the very least are not widely used in my area of the US) and a lot of European countries are less knife-friendly than the US.

I feel like it’s a pretty common experience for a lot of us maker types- we come up with a solution to a problem, maybe we tried searching for one and came up empty, or maybe we just thought it would be fun to make from the get-go, then sometime later we stumble upon someone selling pretty much the exact thing we made and think “huh, so thats what these things are called” maybe with a touch of disappointment that your idea wasn’t as original as you thought, or maybe just intrigued because you just added another term to your vocabulary and you have a better idea what to search for next time.

Yours looks good though, It’s probably unnecessary but I’d be tempted to add like a U-shaped cradle piece to the top to help keep it in place if your computer ever gets jostled for any reason, and maybe a jam nut at the bottom to make sure it stays where you set it. Again probably totally unnecessary, but I always figure that if it’s worth doing it’s worth overdoing.

What sort of printer and filament/resin are you using? I’d worry a bit about it warping or sagging over time from the heat inside a computer. I know some materials can handle the heat better or worse than others, but I haven’t dipped my toes into 3d printing myself yet, so I may be overestimating how much of an issue it is.

And can your printer make decent screw threads, or do you have to clean them up afterwards with a tap and die or something? I’m not really up on the current state of 3d printers, but one of the first 3d printed objects I remember ever handling was back in high school 15 or so years ago. One of my teachers went to a conference where they were showing off new gadgets for computer and shop classes, and he brought back a couple 3d printed crescent wrenches for us to fondle. I remember the screws being really crunchy and they almost but didn’t quite work, so in the back of my mind I’ve always thought of functional screw threads as something 3d printers can’t quite do, so it’s wild to me if we’ve gone from barely able to make even a coarse thread with huge tolerances work to being able to make pretty fine threads with pretty tight tolerances.

Of course back then, they hadn’t even really settled on calling it “3d printing,” I remember that teacher calling it a “rapid prototyping machine” when he was telling us about it, and described it as being “like a 3d printer”

I may be misinterpreting what you’re describing, but it kind of sounds like you’ve reinvented the machinist jack.

Not throwing shade, it makes sense and there’s a reason that machinists the world over use them to tackle the same sort of problem of how to support sagging parts- it’s simple and it works. And coming up with the same solution shows that you have a good understanding of the issue and how to tackle it.

Just pointing it out because I love the overlap between different fields and hobbies, and maybe if you didn’t already know that machinist jacks were a thing you’ll find inspiration for a version 2.0 if you ever feel the need to make one.

I’d also like to see your version when you get around to sharing it.

I think the scam calls are annoying, but it takes basically no effort to ignore them when I’m not in the mood to mess with them, so I don’t mind them so much.

I figure though if I can keep one tied up talking to me for a few minutes that’s one less chance for them to be scamming someone’s grandmother. It’s a tiny drop in the ocean, but it’s still potentially one less person getting scammed that day, and that’s worth something.

Technology connections on YouTube did a video on mini fridges a while back. He focused on the peculiarities of one specific model, but one of the things he did to try addressing some of the issues with uneven cooling was add a fan, and he found that it didn’t really help and made things worse in other ways.

IIRC, the fridge was designed expecting that certain parts would be cooler than others and accounted for that in how the compressor cycled on and off, but with the added airflow those parts stayed warmer than expected so the compressor never shut off.

This fridge very well might be different, and maybe the fan is helping in your case, but you might want to check that video out so you have some things to look out for in case it’s causing other issues that you may not be thinking about.

It’s specifically the size of a small moon, remember that the Earth’s moon is actually pretty large, 5th largest in our solar system and by a pretty good margin the largest in comparison to the planet it orbits, just in our own solar system we have Deimos at only about 6KM, and in other parts of the universe I’m sure they could be even smaller, in our own solar system Jupiter pretty regularly captures small asteroids into its orbit that could be considered temporary moons.

From the various wikis and such, the death stars were about 120 (1st death star) and 160 (2nd) km in diameter, so 60 and 80 in radius, so still significantly larger than a cube, but far less so than the 1000km you’re thinking.

And size doesn’t necessarily correlate to how much power they have at their disposal or how much they can absorb/deflect. Their weapons/shields are probably based on very different technologies, it could be like comparing a Davy Crockett nuke (basically the real-life equivalent of a fallout mini nuke) to an equivalent sized bomb made of black powder, or like an inch thick plate of steel to the same sized sheet of plywood.

And the death star crew was much larger, somewhere around 2 million people plus a few hundred thousand maintenance droids. Those humans need a lot more space and creature comforts than the Borg who just need alcoves to recharge in. I’m sure that they weren’t exactly providing luxury accomodations for most of the rank-and-file grunts and contractors and such, but they certainly got more space than the Borg need, plus dining halls, kitchens, medical bays, recreation areas, meeting rooms, offices, throne rooms, detention levels, etc. a lot of things the Borg have little or no use for. The Borg may be able to dedicate more space on the cube to weapons and shields than the death star could.

Just to be clear, you’re not getting downvoted because people disagree with the idea that the oil industry is a problem that’s holding back greener energy sources.

And most probably aren’t down voting because the guillotine remark being a call to violence or anything like that.

The downvotes are purely because that was a very cringy comment to read, it wasn’t funny, and it didn’t really add anything useful to the conversation.

Yeah, in English soldering and welding are different processes, there’s also brazing, which really kind of mucks the terminology up.

I’m sure you’re probably pretty familiar with the actual processes (probably moreso than me, most of my knowledge is second-hand from growing up with my pipefitter dad and hanging out with a few welders,) but just so you know how we use the terms in English (and for anyone else who’s reading this who might be curious)

What we call soldering is a relatively low temperature process, the filler metal gets melted but not the base metal, it’s often done with a soldering iron, or regular butane, propane, or mapp gas torches, usually with no need for an oxygen torch.

Brazing is basically just hotter soldering, the base metals still aren’t getting melted, it may involve an oxygen torch, there’s also some brazing processes that use arc welders, like TIG brazing with silicon bronze filler.

For the non-welder types, you can kind of think of soldering and brazing as metal hot glue. There’s a bit more to it than that, but that’s kind of the general idea.

And welding is when the base metals are getting melted together, and it’s pretty much always going to involve either an arc-welder or oxy-acetylene torch.

Most hardware stores probably stock about a shade 10 lens, which is adequate for most common welding processes. You really only need to go higher for a handful of processes, like carbon arc welding (darker lenses may be recommended in a lot of other cases, but 10 will meet or exceed the minimum requirement in most cases)

I’ve seen some mixed information about exactly what shade is safe for viewing the sun, but they all agree that 10 isn’t adequate, I’ve seen some sources that say anything darker than 10 is ok, others say darker than 12, and still others insist on 14. It’s probably one of those things that depends a lot of factors, how long you look, how sensitive your eyes are, the weather, viewing angle, etc. I’m no expert and certainly don’t take this as legit safety advice, but I’d imagine you could probably steal some quick looks at the sun with shade 10 or so lenses without causing significant damage, but you probably don’t want to stare at the sun for a few hours for the whole duration of the eclipse.

I have seen a lot of auto darkening helmets that go up to a shade 13. So if you have one, think that’s an acceptable level of risk, and can either set it to 13 or trust it to do it automatically (I kind of suspect, though I don’t know for certain, that looking at the sun may not trigger it as reliably as looking at a weld that’s right in front of you) you can certainly try that.

I suppose there’s also the possibility that the equivalents of ANSI or OSHA or whoever sets the standards for welding lenses in your country, may use a different system or terminology than we do here in the states, which could make most of what I’m saying here largely irrelevant.

Personally I have a pair of glasses made by Phillips safety with shade 14 glass that I used for the last eclipse and will use again for this one. I certainly felt well-protected, the sun was just a dim circle in the sky. Of course the apparent brightness is only part of the issue since UV light is invisible and that’s where a lot of the real danger comes from, but a shade or two lower probably would have still made the sun comfortable to look at, though I can’t comment on the actual safety.

1. Welding mask, soldering doesn’t usually require any special eye protection

2. As others have said, only the darkest shades of welding glass provide adequate protection, and the ones that do are fairly uncommon, most hardware stores and even many welding supply places won’t won’t have dark enough masks or glasses on-hand normally. They may be able to order them, but don’t expect to pick them up off the shelf at your local store.

I don’t know the current state of things, it’s probably more than 10 years since I’ve bothered with rooting and custom rooms and such.

But back then I remember my phone company tried to make me pay extra for tethering and there were a few tricks using root to get around it. I think there were a few apps out there that would work on the stock room that needed root, and I think it just worked out of the box with a custom ROM.

IIRC, at that time, my carrier had disabled the tethering options in the phone settings, and to tether you had to use their pre-installed app. My memory may be fuzzy on that though.

I have a trip to Montreal coming up in a couple weeks, I don’t put a lot of faith in tomorrow’s forecast, let alone 2 or 3 weeks out, but right now it’s looking like theres a pretty good chance of rain for most of my trip, so I have a feeling I’m gonna be really grateful for RÉSO while I’m there.

40mph is probably a bit extreme, but “20mph, tops” is also pretty low

E bike laws, terminology, and manufacturers can be kind of a wild patchwork of nonsensical bullshit but a lot of states recognize, with some degree of regulation or restrictions, what have commonly come to be called class 3 e bikes, that can go up to 28mph, and in my shopping around I’ve seen plenty that advertise that speed or even higher.

There’s a lot of imported e bikes that play fast and loose with the regulations and their quality control, and I’m sure there’s a dedicated bunch of people tinkering with their bikes to make them go faster and remove built-in restrictions, so there’s probably a lot of people zooming around at 30+MPH
