There's nuttin like a Cool Project to give you some relief from the summer heat, so get out your parka cuz we got a bunch of em. First up is the BUG, not a bug, The BUG. It's got a GPS, camera and more, in a hand-sized package that's user programmable. The BUG does everything. It's both a floor wax and a dessert topping. Get one now. Need a software version of a Swiss Army knife? Take a look at Billix, and don't leave home without it. Then, chew on this one, an X server on a Gumstix device driving an E-Ink display. Need more storage? How about 16 Terabytes? Can do.

And, of course, we have the usual cast of characters: Marcel, Reuven, Dave, Kyle, Doc, plus the new kid on the block Shawn Powers. But it doesn't stop there: build a MythTV box on a budget, build your own GIS system, set up the tools to monitor your enterprise and more. Finally, remember The War of the Worlds? Now you can play too.
