Today the Supreme Court ruled against Grokster. “One who distributes a device with the object of promoting its use to infringe copyright … is liable for the resulting acts of infringement by third parties using the device, regardless of the device’s lawful uses.” I’ll update this post as more information comes in, it was an unanimous ruling too.

The energy for a mouse-trap powered cars is stored in the mouse trap spring and it drives a wheel by some arrangement such as a string connected from the trap’s jaws. There was a competition among the mechanical engineers at my University to build a mouse trap car that could travel the furthest. There were plenty of different designs. The winners had a design that released energy from the spring slowly and had only two wheels. Thanks Stuartcw! Link.
If you ever wanted to use an Xbox controller on your Windows PC, here’s how. Exports ~32 controls to Windows: Up to 24 digital buttons, 7 axes(X, Y, Z, RX, RY, RZ, Slider) in Windows 2000/XP, 6 axes(X, Y, Z, RX, RZ, Slider) in 98/ME, POV hat switch with 8 directions Link.

The design was first used in early Atari game consoles but got soon adopted by most home computers of the 8-bit era, best known examples including Commodore, Amstrad, Spectravideo and MSX. I still own a couple of Competition Pro sticks and just love the precise and tactile touch they provide. And here’s how to make one… Link.
Noah has mapped the bumpiness of the streets of Cambridge using an accelerometer he made. Schematics, source and more on his site. It would be great to have these types of maps if cars could record this data so cities would know where all the potholes are. Link.
Here’s a social PDF linking site. Folks can tag PDF link they like and it can be a social library of sorta. It would be great to do this with text files too and then sync them to devices and computers used for ebook reading. I tend to like PDFs on Tablet PCs, but it’s still not the greatest way to read content I think. Link.
The following notes grew out of a search for a good pattern for sewing a cycling jersey using non-lycra fabric. I’m not a great fan of lycra jerseys for touring, preferring a somewhat looser fit and a fabric that doesn’t feel like a wet plastic bag after I sweat in it all day long. Wool is good for cold weather, and polyester for warmer conditions. Link.
