We definitely don’t recommend trying this one, but [Tony] sent in this odd twist on the old potato launcher. A pair of physics students put together a Taser like potato sized bullet. On impact, two metal pins are inserted into the target, delivering an electric shock. Depending on the size of the capacitor and amount of charge delivered, it can be a (sort of) non-lethal or lethal shock. We’d prefer not to be shot with either one.
[Nuri] sent in his rather interesting gaming feedback device. The TrakonyaMutatorUSB is a USB based armband that’s designed to shock you when you get shot or killed in your game. I can’t comment on the safety of this thing, but I guess it could be a good gift for your enemy gamer.
Update: Just to clarify a bit, This is built by [Nuri]. He offers them for sale (via paypal I see), but it is his work. It would be nice to see the design, but I can see some reasons why he might not want to release it to the public.
