The Most Painful Toy Hack
wintersynth writes "We hacked a toy brainwave reader to electrocute people if their brainwave frequency got too high (by concentrating). We took outputs off of the 5 level LED indicator, put the outputs through a transistor/resistor/relay circuit to give 2 levels of high voltage through an electric shock circuit right into the user's arm."
Set it up to electrocute the user when they are NOT concentrating, and sell it as a cure for ADHD!
I've abandoned my search for truth; now I'm just looking for some useful delusions.
