When it comes to all things DIY we tend to be drawn in by odd, internet-connected esoterica and Arduino-powered beer distributors. But, we won’t lie, nothing gets us going like a home-crafted instrument of destruction. And, in that vein, may we present you with the wrist-mounted crossbow from homebrew weapon artisan Patrick Priebe. Usually Priebe sticks with lasers but, for this project, he went old school — as in medieval. The bolt firing wristband isn’t without its modern accouterments, though — a pair of AA batteries and toggle switch are hidden in the palm which power a laser sight for better targeting. We won’t waste any more of your time, everything you want to see is contained in the video after the break.
