I gave a talk at NebraskaJS on hardware hacking, Johnny-Five, and the importance of amateur goofery.
It was the most risky talk I've ever given. I demoed an Arduino-powered Power Glove, modified my slides on the fly with a WebSocket-enabled potentiometer, and flew a quadcopter drone over the audience using a Wiimote.

I also gave a 20-minute version of this at Barcamp Omaha, which you can watch if you enjoy seeing quadcopters crash and burn.
