Yellow Drum Machine (google video), one of the robots that you can learn to build via Let's Make Robots (.com). This little guy finds a surface to tap a beat onto, then taps a beat on it. The fun starts at about 35 seconds in (via b3ta).

Hannu's Boatyard is a site by a Finnish guy who offers free plans for two dozen simple plywood boats you can build, along with photos illustrating the build process of each. He also describes basic woodbending technique and some of the design process, in a pleasing writing style that makes me want to get off the internet and make things. My favorites: Portuguese style dinghy; tiny stubby halfpea; round, Welsh-style coracle -- if you click on no other link today, click on the coracle link and scroll down at least to the black and white photo.

How to build your own violin, in 45 pictures. Or for guitarists: build your own hollow-body, solid-body electric, or steel guitar. For the budget-minded, PVC flutes. How about bagpipes? No? Surely you cannot resist the tribal sounds of the home-built didgeridoo? Other eclectic (and not so eclectic) home-built instruments.

Build your own radio. . . Or anything else, for that matter. Go ahead, release the hidden scientist in you and enjoy discovering and creating.

Create your own little cityscape, using the drag and drop feature offered, and enjoy a little Friday time-wasting fun. Add lots of little pixel people and create your own blackout block party.
