Question Laptop wrapped in tin foil

[bobbobbob]

If I wrap laptop in tinfoil, everything , but not screen... Then my computer will be unable to catch wifi yes? Airplane mode is not the case this time.

Im about to create a wooden box ( 5 sides, 1 side left empty to work with computer), surround outside borders with tinfoil, add computer to that box, and then wrap computer with tinfoil.

This will do no damage to computer? Should I attach cork sheet, ( as cork is good sound isolator - maybe it will isolates emf radation well too ? ) ?


Im talking about emf/rf shielding here.

Sounds like a good way to overheat a laptop.

If doing a break, after every 30 or 60 mins nothing could happen?

Why wouldn't you just locate the vents and cut out holes so the air can flow?

And let in all that EM and RF?

Then why bother covering it in foil to begin with?

 

[mxnerd]

Is this a joke? The best way to avoid EM/RF is to live in a cave.

Yeah, i guess OP could make a faraday cage or something, but that just seems like a waste.

OK, this is the same guy who suspected his PC was hacked by his roommate. No wonder.

In most cases the Antenna of the WIFI is in the Screen Frame.

So leaving the screen uncovered would transmit your "Secrets" to the Galaxie.

You're right and I remember that thread.

I think the OP needs to build a safe room with lead walls and electronic signal scramblers as they must be into some very bad, evil stuff.

Try 30 to 60 seconds. Laptops will overheat fast if you block all the vents.

If you're really serious and not just trolling, you need a room-sized Faraday cage.

Are you trying to wrap a folded laptop in foil for protection while traveling, or are you talking about wrapping the base so the government doesn't hack into it?

May be referring to health conditions, possibly. Or even bridging a gap for controlling wireless signals in a lab.
Technically the box may work.
Shut off the radio signals or pull out the WAN/WWAN/WLAN and go LAN with a CAT cable of your choice, or ethernet the signal to an access point outside of your area.
If and when in the box, tighten the wires and mold them through the seals if anything needs to go external. As far as cooling, mod for extraction of air/ventilation, or custom heatpipe.

Similar ventures can be achieved with a micro-desktop, but if a battery is needed, you can always use a UPS.

For example on my laptop ( every laptop now ) attempts to 'capture' all available wifi networks in range, and displays available network connection's lists - allowing to connect.

I don't know what computer part doing this ( searching and finding network connections - somehow secret'ful working in background ), but I will name it as 'component wifi'.
What actually computer part reacting to those signals?

 

[bobbobbob]

Expanding post.

I am sure that form where you live there some where roads and these roads connect to other roads and you can drive (long time) and even get to Paris.

But you do not wants to get to Paris! so why there is Roads?

The same thing is with Wireless in order to connect to other computers you eed to know what is around and what to connect to. That is why there is WPA2 security Pass word so the cpnnection will go only to where you want it to and come from. It by the computer hardware and the OS.

If you do not want Wireless capacity on the computer, switch the Wireless card Off.

Otherwise, if you are Not running the Wireless capacity of the laptop.

You can try to find out what Auto loads and run in the background by using these free portable Apps.

From reading that thread and this one, I'm wondering if the OP is simply suffering from Paranoia? If so he needs to seek mental help.

 

[aigomorla]

just open laptop and type "allyourbasesbelongtous" and hackers wont be able to get into it.
(sarcasm)

no but seriously... there are so many things wrong with covering your laptop in tin foil, that its on another level then making a tin foil hat for yourself to protect you from aliens.

 

[Mr Evil]

...lead walls...

Lead is good for blocking certain types of ionizing radiation, but it's not very good for blocking RF. For that, you need materials with either high electrical conductivity or high magnetic permeability, depending on the frequency and if you primarily need to shield against magnetic or electric fields. There is no single material that has both, but you could combine sheets of nickel-iron superalloy with sheets of silver to be sure to block everything. It would be expensive, but isn't it worth it to protect your precious bodily fluids?

 

[dave_the_nerd]

FWIW, the CIA doesn't even bother coating a laptop in tin foil. They just air-gap it by removing the wifi card.

It's very '90s.

 

[MtnMan]

Perhaps a tinfoil hat would be a better choice.

 

[GrumpyMan]

Yes this is the answer, place tinfoil hat on head and aliens will never find you..

Why not simply disconnect the Wi-Fi antennas inside? Heck, you can usually remove the Wi-Fi module entirely. The antennas are usually routed through around the LCD screen.

Disable the wireless card in device manager, delete the drivers for it...
