Nintendo DS Motion Card

I’d wait until they ship, but you can pre-order the DS Motion Card homebrew DS development, source and example code on the site…

“The DS Motion Card is a revolutionary motion sensor for the DS and DS Lite handheld gaming systems. It contains a 3-axis accelerometer and a single-axis gyroscope, and plugs into the DS card slot to enable full motion sensing on the DS and the DS lite.

It is the first tri-axis accelerometer that can be used for homebrew DS development, and the first and only accelerometer/gyroscope combination available for handheld gaming.” [via] – Link.
