Gadgets for Gadgets Sake
If your affinity for all things small, shiny and functional is as developed as mine you might find this interesting. The Bug Labs BUGbase, is a general purpose “computer” to be used as a starting point on which you can build anything you want using the add-ons that are also sold by bug labs and of course, it runs Linux. You can add additional modules to the base such as a 2MP Camera, GPS Module, 2″ LCD, and a motion detector!
The gadget is open source and can be programmed in Java with the BugLabs SDK.
