USB Killer

"I burnt down everything I could. Then I ordered boards from China and made a combat model."

The basic idea of the USB drive is quite simple. When we connect it up to the USB port, an inverting DC/DC converter runs and charges capacitors to -110V. When the voltage is reached, the DC/DC is switched off. At the same time, the filed transistor opens. It is used to apply the -110V to signal lines of the USB interface. When the voltage on capacitors increases to -7V, the transistor closes and the DC/DC starts. The loop runs till everything possible is broken down.

    High voltage on I/O lines?

    "No, a SCSI-1 Interface. My machine pretends to be a disk, ID 3. But lots of machines kill my machine's powersupply with inductive transience backflow due to a non-standard SCSI interface…”
    "Okay, let's see what we can see" he says, and presses the power-on switch on my "portable" The 31 hefty nicad batteries that make up almost the entire inside of my "laptop" pour grunt into a tripling inverter which in turn supplies RICH, CHUNKY VOLTS to alternate pins on the "SCSI" bus, whilst emitting a dull "uuurk” sound.

    Reminiscent of this scary image:

    I didn't see a demo video. I really wanted to see a video.

  4. When I saw this I thought "cool hack," but none of my computer nerd friends agree with me. Something can be cool without being "good".

    This is still not as evil (or cheap) as a proper USB stick preloaded with a RAT, or whatever.

    Also, it should say Sony or SanDisk on it.

      No, it should say "Do Not Use" on it, because that's the best way to get someone to plug it in, and afterwards you can say "well it did tell you not to".
      Then leave it in your bag as you cross international borders and enjoy the many and varied lockups you get to spend time in :)

        Totally unsafe to keep around your own stuff. Somehow, it will end up in your own computer. It's a law, I think. In my case, probably via children.

    Reminds me of an old weird bit of military communications equipment that had some some bubble and donut memory, both of which retain info without power. Strangely, there was a connection on the back for something to do with a battery for the memory which was adjacent to and the same kind of connector as the AC power...

    Someone has already done something similar on Indiegogo
