Ever wandered what forces affect you on a roller coaster? Then build this Accelerometer logger which stores acceleration data to SD memory which can be analyzed later.

Acceleration is read using 3-axis LIS3LV02DQ inertial sensor from ST-Microelectronics, a uALFAT from www.ghielectronics.com to manages the SD-card interface, information is displayed on HCMS2915 display. All control is done with PIC16F876 microcontroller. PCB board is mounted to plexiglass, where necessary holes for battery pack and other components are milled. Probably this is really fun thing to take to amusement park with you.
