This is a quick heads-up on a post on a Lego Mindstorms NXT blog by physicist Brian Davis who rigged up a third-party 3-axis accelerometer to his NXT controller brick to create a portable motion datalogger. He datalogged and graphed several Disney World rides complete with annotations. Some custom code on the NXT logs +/- 2.5 Gs of acceleration from the 3 axes at 1/10 sec. intervals. The data was plotted to LabView. Rad! And I can think of some other recreational activities that would be fun to datalog…
