Here is the first of several runtime plots of modified and unmodified flashlights that I'll be doing. This one is for a AA Minimag with a Madmax Sandwich. the test was done with fresh Everactive Alkaline batteries.
Equipment used is a photo cell and Radio Shack 22-805 mulitmeter with a PC interface that is using ScopeView software (V 1.08).
Edited: New plot on 09-12-02
The vertical axis is in Ma and the Horizontal axis is 15 min per division.
It was pointed out that to use the photocell properly, measurments of ma and not mv were needed. Thus a new chart.
