The XBee & XBee Adapter Kit bundle from the Maker Shed is designed to make adding wireless point-to-point or mesh networking to your next project a lot easier. The kit includes an XBee, the XBee adapter PCB, and all components necessary to build the adapter. This kit is really easy to build, even if you’ve […]
Tokyo-based wireless hacker Akiba of FreakLabs sends word of their latest project, the Freakduino-Chibi, an Arduinoid with open source 802.15.4 protocol stack and integrated radio.

his very clever design by Derek Engelhaupt has me looking around the house for something I can put tank treads on. The sofa, maybe?

“One of my favorite things to do is talk with other ham radio operators through satellites or the International Space Station (ISS). To do this, I stand on a rooftop and tune a handheld multiband radio while tracing the orbit of a satellite or the ISS with my homemade yagi antenna.” So says Diana Eng, […]
As you may have heard, last week in Stockholm a bunch of lucky stiffs talented, hard-working scientists (and one fiction author) got to meet the King of Norway. Science-y highlights include the Physics prize, which went to Andre Geim and Konstantin Novoselov for some fancy tricks with carbon (specifically graphene); the Medicine prize, to Robert G. Edwards for inventing the test tube baby; and the Chemistry prize, to Richard F. Heck, Ei-ichi Negishi, and Akira Suzuki for, ah, some other fancy tricks with carbon (plus palladium). That’s all well and good.
