They're really nice when packing or inventorying bulk components, IIRC ours have the option to calibrate on 10, 25, 50, or 100 components. The manufacturing tolerance of the parts plays a big part in accuracy. For things like metal screws and nuts it's really great, but plastic standoffs and LEDs have a surprising amount of weight variation - when I used to do it we would overcount by 1-2 to guarantee <em>at least</em> as many pieces as we listed.</p>

If memory serves, you'd count out 10 of the part, but them into the hopper and press a button. Then you'd dump the rest of the parts to be counted and the scale would tell you how many. (I think that the "accuracy" of the count depended somewhat on the weight of the parts being counted -- more accurate for heavier items, less accurate for light items, and if you had really light stuff you'd have to start by counting out more of them.)<p>I've got an older (15 years maybe?) kitchen scale that the "non-replacable battery" died in a few months ago -- maybe sometime I'll open it up and see if I can use the load cell.</p></p>

(It's gonna stick out in the collection, at least for a while...) FWIW, I use several red boxes to "organize" my parts collection (with Post-It notes attached to indicate what the contents are), plus a few have projects built in (or on) them.</p>
