An article about the bomb-drive, first posted on the Russian website Habrahabr.ru by its designer, describes its design and intended effect:Scary. Of course, anyone who picks up a thumb drive and pops it into their computer is asking for trouble.
"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."
