Use activity tracker as datalogging accelerometer
Use activity tracker as datalogging accelerometer
(OP)
I was looking for a backlogging accelerometer and realized that is what the activity trackers like Fitbits do. Has anyone been able adapt one of those for engineering testing?
Can you get the raw acceleration data out instead of steps?
Which one do your recommend?

Toy ball for my kid had cheap accelerometers in it. Inside the ball was a cavity with a tiny circuit board and when the ball was bounced, LED's would blink. The accelerometers were just springs, one end soldered to the board. Around each spring was a metal tube, so if the ball was hit hard enough, the spring would touch the tube, making contact. Couldn't shake the ball hard enough by hand to make the spring contact, but dropping it on the floor worked every time. Until the dog chewed it apart, that is...

A datalogger with an accellerometer that will store and output acceleration data (I maybe able to use step counts).
1 hour of storage O.K. 1 week better.
size equivalent of fitness tracker roughly 6cm X 3cm x 1 cm. Smaller is better.
cost of less than $50 wholesale.

add battery and use your cellphone or laptop as logger.
If not that, then:

Strong, there are activity trackers that retail for $50 which have the right hardware. So $50 wholesale is not unrealistic.
Thank you IRstuff. It looks like no one here has had any success adapting something. So I will need to get deeper into the hardware. These are very interesting options.

Here is another approach to an activity tracker that might give you direct access to the data.
