Li-Ion (18650) battery capacity meter

As of many hackerspaces we rescue 18650 cells from old laptop batteries and other sources
We do have a charger but no good way of testing the capacity of each cell before it goes into the parts pile
Making a capacity tester would solve this. One could buy a chinese unit from fleabay but where is the fun in that? :)
