I have an Ohaus m5 like in the second video. Got it off ebay, pretty chipped up and abused. without any tune up, It will show every kernel of h4831, and goes back to zero at the end of the batch. I would like to do the extended needle. I did try an endoscope/bore cam hooked to the laptop. It was nice not having to worry about the visual discrepancy caused by the angle of the dangle. I need to make a real mount for it.

My 20$ digital scale tries to kill me with inaccuracy and creep.
