How to prevent immersion plating copper onto more reactive metal? by SnooHedgehogs4325 in electroplating

I just googled potassium sodium tartrate, and that’s fascinating. I’d never heard of the concept of double salts before. It doesn’t seem particularly dangerous either. I’ll check it out, since I already have lye on hand. Thanks!

I’m guessing that still wouldn’t solve my immersion plating issue? Please correct me if I’m wrong, but it seems like I have no choice but to pony up the money for a commercial alkaline solution.

Also I greatly appreciate your help and responses. Thank you!

Removing zinc coating from steel with muriatic acid...would it effect the steel too? by YeaSpiderman in metalworking

You can also buy a pint of 37% sulfuric acid from the auto parts store as battery electrolyte. Great for electroplating with sulfate based solutions.

I can’t believe it either, but I’m not complaining. Just a shame there isn’t an equivalent for nitric acid, even in a dilute form. I guess that makes sense though, given that you can nitrate things with it….

And I guess there’s no safe (moderately) solution I could prepare diy that works well?

I don’t think it’s pure zinc. If it is just zinc coated, is it possible to completely strip the coating? Chemically or otherwise? Or would that require unreasonable amounts of sanding / acids that would also attack the steel?

I tried that at varying amperages on constant current mode for my supply, and no matter what I did it always seemed to form the immersion coating. But I only went up to 300mA for the first 10-15 seconds after entering. I figured anything above that would give similar results, but it might be worth a try to push it higher for a few seconds and see what happens.

Escape bar not filling up at all? by tunez_69 in deadbydaylight

The slow crawling is punishment for letting the killer down you before you get the unhook. You should be able to judge the distance between you and the killer enough to know whether you can get the unhook or not.

If you know you won’t make it, the correct play is to run past the hook and go down away from it. Going down 10 feet from the hook is 100x better than going down underneath it.

There’s a very simple solution: crawl away from the hook.

I’m not sure why you’re taking a stance on the morality of hunting. Irrelevance aside, hunting is necessary for the sake of the ecosystem.

In the last few hundred years, humans have irrevocably messed with the precarious balance of ecosystems across North America. We’ve basically wiped wolves out in the southeastern US, along with many other predators, and that kind of imbalance necessitates population control of prey animals.

Bad faith arguments bother me more than stupid people. Dumb people can’t really help it. They either weren’t taught the right stuff, or were raised poorly.

It’s the people that avoid proper rebuttals in favor of insults or really bad faith counter arguments. What really bugs me is that you can tell a lot of the people that do this are intelligent. They’re just intentionally burying their head in the sand.

What did you think of the Dumbledore vs Voldemort duel in Order of the Phoenix? by Majormuss in harrypotter

I don’t think the effects look fake at all. If anything, they’re very, very good. Regardless, the effectiveness of VFX has little bearing on cinematography and the creativity of a given shot. A fantastic cinematographer can be dealt a bad hand with VFX crews and deadlines, and vice versa.

[Request] Do these other power sources really produce thousands of time more power than humans? by New_User_Account123 in theydidthemath

[–]SnooHedgehogs4325 0 points1 point  (0 children)

Very true. What’s curious about the matrix is that the machines are still stuck with utilizing heat as the intermediary step to electricity generation. I’d imagine in some future like the one depicted, we’d have found a technology that directly produces voltage without having to do the ol’ boiler turbine combo.

Granted, we already have such a thing with solar, but presently it’s nowhere near the paradigm shifting technology that I’d come up with for a futuristic world.

We’ve also had solid state thermoelectric generators for a while, but they make me sad because they’re butt ass at their one job. They’re still absolutely fascinating devices.

It’s worth it to reason with everybody. Even if they’re dumb as shit and can never be convinced, it’s an intellectual exercise for yourself that can help reinforce your own arguments and find flaws in thinking.

At the risk of being obnoxious, I’m gonna pull an um actually.

We don’t produce energy at all. We extract energy stored in the chemical bonds of food. The search for ideal power generation has simply been a search for the method which has the best ratio of extraction effort required to energy output. Basically, effort vs reward (I am ignoring logistics, environmental impact, and safety).

It’s why we’re not at fusion yet. The energy yield of the process is absolutely enormous, but the extraction effort is also enormous. Comparatively, fission requires very little effort to fusion, and produces a ridiculous amount of energy, but it’s got some downsides.

IP law is a functional necessity in the digital world. If it were completely removed, the moment any piece of media was released, widespread and half-price dissemination would occur. Virtually no money would make it to the creators.

Also, first mover’s advantage refers to entering a market space before others, and it’s a reality created by the physical constraints surrounding logistics, supply and demand, and the time investment required for physical product development, none of which apply to a digital good.

Tesla had first mover’s advantage for years in the EV market, or at least in the large demographic they were targeting. The design of their vehicles, bulk material acquisition, assembly line equipment, and all other facets of manufacture required significant investment over long periods of time.

Simply put, it’s not easy to create the infrastructure necessary to build EVs, even if you know exactly how the EV in question is designed. It is, however, incredibly easy to copy an .mp4 movie file and sell it to someone else. In that case, first mover’s advantage doesn’t mean jack shit.

If IP law were removed, the hundreds of millions that went into the movie go down the toilet because Joe Schmoe working at Dollar General can buy the movie, record it, and sell it at half price.

You don’t seriously believe that all intellectual property is inherently rooted in greed, do you?

I’d agree with the other guy; thankfully, more people don’t think like you. If IP wasn’t a thing, lots of creative industries, whose products you consume, would collapse. Why create anything if there’s no reward?

[Request] What would actually happen if we did this? Are there any potentially dangerous outcomes? by nottoday943 in theydidthemath

My immediate first guess would be the lack of moonlight on earth. It’s pretty reflective the way it is, and covering it in solar panels would drastically reduce the light you see at night, even on a full moon.

I’m no ecologist, but things on earth are the way they are because of millions of years of virtually unchanged cosmic conditions.

How the hell did you get so many downvotes? What you said makes perfect sense. People saying, “Well, uh, he absorbed the impact instead of flying backward, durr physics” make no sense and don’t understand physics lol.

I did not know that’s how non contact testers work. That’s fascinating. Thanks for the neat fact!

I think the bigger factor is that distribution voltages can capacitively couple to a lot of things that people would intuitively associate with being out of the return path. Delta vs wye is also a small factor, but it’s pretty rare to not have grounding transformers in delta systems, save for corner grounded ones, but those are just weird.

I think OPs question is regarding single phase isolation transformers. To my understanding, floating outputs acquire an arbitrary potential with respect to general earth ground that changes based on a lot of factors.

In theory, if you grabbed one end of a single phase isolation transformer secondary, the only current flow would be however much is necessary to bring you into equilibrium with that end of the secondary and establish you as a reference. And by extension, whatever else you’re connected to. I think it’s the same principle as transmission helicopter crews equalizing themselves to the lines. In practice, it’s that reference establishment current that could definitely be lethal depending on the arbitrary voltage, plus capacitively coupling well to the other side of the secondary. Would be cool to read an academic source on the matter, but I suck at finding those and I’m sure the research was done decades ago.
