Multimeter reader
#1
1. Use phone camera to convert a multimeter display to a series of data points, with varying time interval. 
2. Same as above but allow simultaneous capture of multiple multimeter displays 

Phone could then be mounted above multimeters to allow for nice data processing of almost continuous data. Great for capacitor discharge, cooling curves, internal resistance, etc.

So, for example, if your camera was pointing at the multimeter shown below, it would store the number 21. The important idea is that the values are stored as a time series, so that you can analyse how data is changing over time.
