Percussa micro super signal processor

Angle grinders, screwdrivers, a sledgehammer. All important parts of your live rig if you’re part of 5VoltCore. Here’s the video, and the show description (thanks emanuel):

We mount cables stripped of isolation on an audio amplifier and use these to create short circuits and faulty currents on the chips of the graphic card of a computer.
The intrusion of the amplified music signal in the graphic card causes the computer to get electrical impulses on parts of the hardware that are not designed to receive them.
