I spent the last weekend at EMF. It was a blast. Apart from the talks and “official” activities being just plain awesome, the atmosphere was fantastic as well.
One of the cool things I get to physically bring home from EMF is a pair of TiLDAs (one of them gifted to me by Jeremy (who, by the way, is working on an awesome project and you should all be keeping an eye on him)).
The TiLDA is EMF camp’s badge, something very common among hackcamps in general. This particular one, has two RGB LEDs, a 2.4GHz radio transceiver, a 1600mAh LiPo battery and a IR LED.
This is particularly interesting because you can do fun stuff like turning off televisions with it:
