I have been building devices and researching interface experiments for years but only stumbled onto Rob Faludi when researching other Xbee projects.  Looking at his blog archives, he’s been doing interesting things for a couple of years at least.  Wonder why I’ve not run across him till now?  He points to New Micro’s useful Xbee USB carrier, which is just the ticket for a quik Xbee-PC connection.

Rob also has been experimenting with some really cool networked objects.  Check out his slinky metronome, for example.
