DESCRIPTION
Use UptoPlay to play online the game BatteryDrop.
BatteryDrop estimates the life remaining in common alkaline batteries utilizing the bouncing batteries phenomenon. It listens to 3 successive battery drops on a hard surface and uses an algorithm to determine the bounce heights of each and predict the remaining charge.
Due to limitations in the phenomenon itself, BatteryDrop is unable to accurately predict the charge of batteries with less than 40% charge remaining.
Currently supported battery types:
- AA
- AAA
This application was inspired by a Princeton study, which can be found here: https://www.princeton.edu/main/news/archive/S42/72/95S25/index.xml?section=topstories
It explains the science behind this phenomenon, but also shows that it is impossible to detect a difference in heights below 50%. (Our system works in increments of 20%, which is why 40% is the lowest detectable charge.)
Enjoy with UptoPlay the online game BatteryDrop.

Comments:
I tried this app out of boredom, but it surprisingly works as advertised. It doesn't really work with softer surfaces or when there's significant noise when you're testing though."
