News - Fun with a Programmable F…

The biggest issue is that the flashlight is cylindrical, so it can easily be experiencing acceleration due to rotation while in freefall.
The best you would be able to do is detect a short, large number of Gs, then a long period of 1 G down - but then how well will it handle bounces? And each axis can only read up to 1.5 gs of acceleration - if the light hits on just one axis, that’s the /maximum/ impact you can detect.
I’ve recently been looking at accelerometer stuff again (but mostly with gesture recognition in mind). I’ll consider the free-fall detection as I’m considering what can be done.
No public wish lists :(
