It would be nice to have some definite indication of how much, by putting a mechanical load on it. Something like a miniature de Prony brake.
I mean that since the machine produces mechanical motion, it makes sense to measure that directly, rather than -- say -- converting it to electricity which is then converted to light. The fewer steps, the better.
You can also use it to run a pulley and lift a small weight, using fishing line.
