It’s so those damn cheapass bitches who waste your time hitting you up for a lousy point don’t get a single goddamn microgram they haven’t paid for.

This ain’t no charity…

>>cocaine distribution.

Correction: Exceedingly accurate small-quantity cocaine distribution

I see that it’s really neat, but for what sort of practical use might this be deployable?

See http://www.physorg.com/news3533.html for what I’m talking about. Its kind of like a taylor/fourier expansion when weighing things. The DC or constant terms can be used, but more data can be gathered from considering perturbations (higher terms).

That hack came out about 5 years ago… But in any case, they can be made quite a bit simpler, see http://www.sci-spot.com/Mechanical/balance.htm for an even simpler design; with a digital readout!
