Caleb sez, "I wanted to try making something in the style of "Q" from the James Bond movies.
My idea was to make an emergency self destruct system for laptops and portable hard drives. It turned out pretty well, it is always fun to watch stuff melt!"
I wanted to implement thermite as a self destruct mechanism inside the device. To do this, I had to come up with a way to ignite the thermite. This stuff is very difficult to light. You have to get it really really hot. The easiest way is to use magnesium, which itself isn’t the easiest thing to light.
What I finally landed on was an ignition system that uses model rocket igniters, gun powder, and magnesium to light the thermite. The model rocket igniter can be set off from the 12v line inside your computer. However, it isn’t hot enough to light magnesium shavings, much less thermite. To get it to work, I needed to add some gunpowder. A small amount of gun powder would get hot enough to light the magnesium shavings, which in turn were hot enough to light the thermite. I had to be careful though, because too much gunpowder would cause a rapid expansion, blowing the thermite everywhere instead of lighting it. You can actually see some red thermite being blown out of the external hard drive and the laptop as the gunpowder ignites.

Doubtless you’ve laughed at the ideological war between the Judean People’s Front and the People’s Front of Judea. I laughed along with you: having grown up in politics, I know firsthand about the enmities that fester between groups that should be allies — groups whose differences can only be parsed after months of study, but who are seemingly more at odds with one another than their obvious political opponents on the “other side” of the debate.
