You can buy adapters, for some barrel jack sizes, to convert the barrel plug to screw terminals so you don't have to destroy the cables. Something like this

330 and ceramic it is most likely 330 pf (picofarads). Certainly a picture would help.

Ok mains power you need a license to build an appliance. If not you must live in developing country.
 
most hot plated use mineral insulated elements.
so inner core is a high temp alloy, I believe it has nickel or tungsten but I'm not 100% sure of its make up.
this is coated in a ceramic
this is then coated in another metal I am not sure exactly what the metal is.
this allows heat transfer with electrical isolation. It is also why they take longer to heat than an induction/glass top stove. This is also why they break easily. The manufacturing process is not great so under Aus/nz regulations they get more leniency for resistance to earth.
 
if you want to build a heater that is not illegal then look up peiltier coolers. You should be able to run it off a battery. In my country It's only illegal to build stuff when it's connected to the mains

I am actually licensed in nz so do not tell me what is legal when it is not. Like I said you must be in a developing country to be allowed to build an appliance without license. In a country with standards, anything that connects to mains must comply and go through a safety check by a licensed worker.

The amount of heat dissipated by the typical case is miniscule. It's all about ventilation, irregardless of it being wood, aluminum or steel. 

I mean, you really can't. Every PSU manufacturer has made some duds, and their warranty service can change. Remember, Newegg used to be known for the best customer service in the industry less than 10 years ago, and look where they are now. Seasonic and EVGA probably have the best warranty services and the longest standing reputation with their warranties (which realistically for this situation is what you want to look for, basically all of the major manufacturers have at least one very good PSU in their lineup, even Gigabyte, so their warranties are what actually differentiate them), but again, they can change on a dime if some of the upper management changes. 
 
In the current market conditions, EVGA or Seasonic (it's a flip of the coin for either one) because of their currently exceptional warranties, but again, If there's one thing in the universe that's consistent it's that nothing is consistent. 

My Pioneer arm begs to differ. It consumes 300w, has no active fans.
 
As does my DIY server which has been running just fine for over a year. As do many other peoples long term builds. The absurdity of people thinking that a wood computer case is a fire hazard due to temps is nuts.

There is really no need to worry about it becoming a fire hazard any moreso than anything else made of wook in a house. Not sure how old you are or when you grew up, but virtually every TV, amplifier, radio, stereo etc was made of wood back in the day.

The ports are already grounded through the motherboard groundplane much more adequately than an IO shield that touches a painted case. 

Its far more likely you are building up a static charge and when you touch the keyboard its being grounded over the USB cable and discharging it.
 
I also have to be careful when plugging in external powered USB HDDs, as the HDDs PSUs have no ground I can see a visible spark as the USB cable ground comes into contact with the REAL grounded connector on the PC.  If my finger gets in the way you really can feel it.

Neither of these things are a problem with the PC.

Obviously it doesnt seat into socket properly one way or that adapter isnt making contact to its pins internally

just use pliers and bend it up and down or just bend them flat

To you have access to the terminals of this magnetic sensor?

If you do you could perhaps solder on some wires and a switch and see if crossing them will do the same thing, I mean at the end of the day it is just a switch so you could remove the mag switch and put in a normal one.  

Instead of using a hub and having to worry about rollover why not just use a few extension cables and keep the ends tied up somewhere that's easy to reach.

The "manual is more efficient" trope is going away, as people have pointed out. Dual-clutch and CVT gearboxes often fare quite well. And while manuals can be theft deterrents, I'd rather have technology that prevents thieves from getting into the car in the first place!
 
Really, though, unless you live in a manual-heavy country or are an enthusiast who wants to drive stick for a few more years, there's not much reason to learn anything other than automatic. Autos already dominate in North America, and EVs will make sure they dominate worldwide.
 
I know some people are attached to manuals, but many (if not most) people just see them as needless complexity. To me, clinging to manuals is like insisting you'll drive combustion engine cars forever — it's a fight against superior tech driven by irrational desires for familiarity or a more sensory experience. Me, I like the thought that a gear-free EV can thrash many comparable manual ICE cars while making virtually no noise.

What fans are you using? I know sleeve bearing fans don't like being upside down. Id try using a ball bearing fan and they should be fine upside down.

It's probably because of the bounds on the for loop. You have it got to "i<=25" but the array is only 25 elements, so accessing leds[25] is actually accessing the 26th element of the array, which doesn't exist. I would guess segNr is stored in the memory after leds[], so it's getting affected. You can try printing segNr in the loop body to verify.

Fun (or not so fun) fact: "electrocuted" is a word made from the words "electric" (or electricity or electrical or whatever) and "execution," meant specifically to refer to an execution by electricity, death, not just an electric shock which seems to be how it's mostly used nowadays.

This may sound pretentious, but that is quite honestly what learning is. You look at a source, study it lightly to judge whether you think it contains what you are after, then read it more carefully and either conclude you learned something or that it was not what you were looking for.
Of course they intersect. It's not like engineering for cars has a different theory of gravity or aerodynamics compared to engineering for planes, for example, but they are different specific sub-fields of engineering with their own set of methods to consider. These can be surface level differences like a plane having a different shape compared to a car, to being "allowed" to take big short-cuts without repercussions in one case that would wreck the other. Say from an aerodynamical point of view for a car you can probably get away with the bare minimum of simulations using very simple approximations just so that you don't fabricate a inefficient brick shape, but a slightly less inefficient potato shape.  Don't do the proper simulations for a plane and it may not even take off at all.
Welcome to the front lines of science; where nothing works and nobody agrees. It can often seem like we've got it all figured out and that science is just a manual that we follow, but that's not the case. In reality there are many different points of view about how we think things work. That's how we progress. You say phenomenon X works through A, I say it works through B, then you test A, I test B, maybe vice versa, and we try to draw a conclusion from that. That conclusion can be anything from it's actually C to both A and B are equally likely and at this point in time almost personal preference.
 
The best I could do list wise is to just refer to Wikipedia or various universities on what they classify as their CS curriculum. Studying is highly nonlinear and starting something new is often the most difficult. I'd say just browse those lists and superficially explore each item, constantly putting it back in the context that spurred your curiosity: what is it that you were actually trying to figure out or learn about. Was it "how can my montior refresh 360 times per second !?" or was it "how does that enemy decide on the best path to get me?".

It's called history, not cultural bullshit. Science is about why things work the way they do as much as how theories (even ones that turned out to be incorrect) shaped our view and guided our research. Giving you this gives you both context of how we arrived at what we now think is correct, as well as teaching you the evolution of thought processes. Even incorrect theories can be a useful stepping stone to the correct ones (e.g. the Bohr atomic model isn't completely correct, but still useful)
 
It's a book. It's literally made specifically to explain these things to you. If you don't care for it, just skip to the bits you want to read and just read those. A good textbook will still have the detail you are looking for. It's just that your knowledge will have no context.

the ability to use custom (apperance and lenght) cables cables from fully psus ususally look nicer and are easier to manage replacing broken cables those are the reasons that come to mind right away imo
 

SATA Connector according to ATX standards are rated for 54w. Not all power supplies are made to fit ATX standards despite being called ATX power supplies. 9 fans and 54w is A LOT, fans are usually 3-4W each if you arent running delta fans (which can use around 50w per fan). Anyways I got nothing further to add to this topic. 

They look like just thumbscrews, I think SSDs use m3 size.
McMaster-Carr has a pretty great website that allows you to search for parts like that.

Cloud backup company Backblaze famously releases their HDD use/failure stats
https://www.backblaze.com/blog/backblaze-hard-drive-stats-for-2020/
And they mostly use regular consumer class drives. I think it's mostly useless to try to guess which brand/model of drive will fail just based on stats, the better approach is to have multiple levels of backups and redundancy to make sure that when a drive fails, you aren't completely screwed. Coincidentally, a service like Backblaze is pretty convenient for that purpose, and fairly cheap.
