Hey there, lovers of action movies. You know that stun gun they use to freeze bad people. When it hits a victim, they vibrate like they’re suffering from an epileptic fit. There’s a flash drive that can actually do this to you computer. It doesn’t stop there, this flash drive can actually go ahead and severely damage your computer.
The brain behind this innovation calls himself Dark Purple. He describes the device as an electrical loop of surges. For techies:
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. Those familiar with the electronics have already guessed why we use negative voltage here.
So from henceforth, be mindful of the flash drives you plug into your computers. Before you see magic happening right before your eyes 😀 Below is a video demonstration of this flash drive in action.
