Looking for a website

[Morphes]

I remember an article on a website about how they hooked up an emergancy button that would incinerate all the computers hard drives and I was looking for the link, anyone remember what I am talking about?

It might have been on THG but i am not sure.

I believe they were using thermite for that, I forget the exact site though.

thats cool, but I remember a guide on how to do something similar in case you get a bad knock on the door lol

So new question! Is there a way to create a safety switch if you get a bad knock on your door, even while the computer is running so it will erase all data?
