RE: Nano Rocket #2 : An Accelerating Truck

Dubbie,

The data does seem a bit more reasonable, in that there is a clear z-axis (yellow) that shows ~1 G. The x and y show the impact quite well. I assume that the blue trace was inline with the forward movement (perhaps inverted, or pointing away from the motion, as the large positive spike seems to show acceleration versus deceleration). The noise could be caused by slight out of roundness of the wheels or surface imperfections in your MDF.

Integrating the acceleration (or even simple adding/accumulating), might show you the velocity.

Anyway it looks like progress and fun!

You could do a lot of interesting projects with your little truck.

Try using the acceleration to determine velocity and distance.

You can try to do a simple inertial measurement unit to keep track of position based upon acceleration and time.
