So I would like to detect the energy contained in each 'bump' (EDIT: Removed a ton of gumpf) Can anyone help me crack this one? Thanks to one of the wizards on freenode's #math channel (thanks Igor), I have a really good working solution. You use the standard method to fire a callback at the maximum frequency possible (100Hz), which will contain the instantaneous acceleration x,y,z values. I will let the code speak for itself, good code should
