Faraday Cages for PCs? Huh?

This is somewhat analogous to the radiation damage that, according to some scientists, prolonged usage of cellphones might cause in the long term.

This is bull-fucking-shit. Cell phone radiation absolutely with 100% certainly does NOT cause cancer or any other long term problems. The only people promoting this are people making money from scaremongering. The science behind this is extremely well understood & has been known since nearly the turn of the 20th century (Albert Einstein won a Nobel prize for his work in this area.)

Going outside for 1 second on a sunny day exposes you to many many many many orders of magnitude more ionizing radiation than a cell phone will expose you to in a lifetime.

On the off chance that you're serious, look inside your case. What are the case walled lined with? Now think about what a faraday cage would consist of, and kindly lol at yourself.

A faraday cage requires any grounded metal. My computer case isn't grounded and neither is yours. This is why your motherboard can "short" if not installed properly and will fail to function.

Your computer case is NOT a faraday cage.

You do NOT need one, either.

I thought a computer case would be grounded through the power supply to the outlet. Is that incorrect?

facepalm

Edit: nevermind. Look it up.

Are you embarrassed by suggesting that a computer case is not grounded?

If not YOU SHOULD BE.

As for you motherboard "shorting" if not installed properly and other nonsense, how in the hell did you come up with this?

And yes, a metal computer case will act as a faraday cage.

Nope, I'm not. You've obviously never installed a motherboard before.

Additionally, if I put my cell phone into my computer case and close it up and call it, it still rings.

You lose.

What the F do you think is going to happen if your improperly installed motherboard touched the GROUNDED metal case?

Hello. isn't that rather OBVIOUS?
As for using you cell phone in you computer case, go right ahead, I have better thing to do.
 
I took a power supply out the closet. I measured continuity from the ground pin on the power connector to the power supply chassis. There was continuity.

The PSU case is grounded. Assuming you attached the PSU to your metal case, then your case would also be grounded.

So no more debate, case == grounded.

I'm sitting 3' away from my computer, and the side is off. I took it off a couple years ago, and never put it back :^D

Oh yea, my wireless router's sitting on top of the tower :^D

Ground is an interesting term in engineering, as it doesn't exactly refer to the physical ground, but a large conducting plane with low resistance. I think in general all that's required of 'ground' is a large conducting surface for charges to spread out on and thus minimize the field strength. Your cellphone has a ground plane.. it's not connected to 'ground' 😛

I'm not worried, the thought-stealing waves from the black helicopters cancel out the PC radiation.

not for me. I use leaded-paint on the walls of my apartment to block out the waves form the black helicopters.

Sure, this helps for that, but creates an internal vortex of RF and radiation from my PC that just bounces off the walls and all over the room, magnifying in strength with each return.

FML. 🙁
 
It's also worth noting that the idea of stopping the bouncy kind of waves is just stupid. Waves that reflect will pretty much never give you cancer. The ones you need to worry about are the waves that soak into things. Microwaves and radio waves bounce off walls and mountains and clouds and they never seem to hurt anyone. Dangerous light like sun light doesn't reflect; you can stop it by putting something opaque in front of it like an umbrella or a computer case or clothes or....

Grounded often means something is tied to the neutral voltage. In your house you have a black wire, a red wire, and a white wire. Black to red is 240V, and white is in the middle at 120V to either of the other two. White is the neutral point. Green is electrically the same as white. Things are grounded because they are tied to green, which is tied to white, which is neutral between red and black (and sometimes blue). DC ground works the same basic way. Green would be thought of as 0 or neutral, red is positive relative to green, black is negative relative to green. Tying things to the DC ground means you know what the voltage is between grounded things and hot things; no more floating voltages and signal interference.

So then what happens if you tie things to the red wire instead of the white or green wire? Well then it's not grounded. It's hot. If you want to get technical, then tying everything in the world to the same hot line would work, but we don't do that because it's needlessly dangerous. If you get a ground fault from red to white or black to white, it's just 120V. If you tied everything to red, then a fault against the black wire would be a 240V fault. That's much much worse. It's safest to "ground" things to whatever electrical point is the most neutral. That keeps the voltages as low as possible when things go wrong.

Actually, waves only bounce entirely when they meet perfect conductors (zero potential everywhere). In general, a wave gets partially reflected and partially transmitted whenever it encounters a change in medium. However, transmitted does not mean absorbed. That depends on the conductivity of the material, which is not derived from the material constants. As for what absorbed means (whether it's good or bad), I don't know anything about this 😛

And I'm sure this will be obvious once you read it, but how do you think your food gets cooked in a microwave?

I actually made my entire house a Faraday cage. You can never be too sure when it comes to Google monitoring.

Unless you're going to tempest-proof every single cable and wire coming from your house, a faraday cage can't help you, nooooooooob!

WE ARE THE GOOGLE. RESISTANCE IS FUTILE.
