A small acceleration sensing device in form of a USB stick.
TiltStick (by Till Harbaum) is using a two axis acceleration sensor to measure acceleration. The device is emulating a USB joystick and can thus be used in conjunction with any USB equipped host without any special drivers. (The USB interface is based on a well known pure software implementation AVR-USB.)
Two versions of the TiltStick have been designed based on different 2D accelerometer chips. The slightly smaller one is based on the Analog Devices XL203 (or XL202), the bigger version is based on the Freescale MMA7261.
