a balance is such an important piece of gear for a mad scientist, and some of us are "destitute" but that doesn't mean we need go without one, or that
it not be pretty damned accurate. This thing was clobbered up out of a 4" scraper blade, a couple of those "wonder wall hooks" scrap sticks, paper
clips and plastic drink bottles. ONE DROP of water sensitivity.
I use US coins and a syringe of cold water as my weight set. 1 cm3 is one gram, and a u100 insulin syringe breaks that into 100 parts smaerd - 30-5-2014 at 17:23
I have to say this is one of the most ghetto but functional designs I have seen on this forum. Dig your style! Probably works just fine for a lot of
applications. Looks like you use spare change as a counter balance? My only suggestion would be to get some better weigh boats hehehe. arkoma - 30-5-2014 at 17:57
The beam is 45 inches long, balanced on a razors edge. Pretty damned accurate and repeatable. Yes, i use coins. A current US cent weighs 2.5 gm,
and water, well, 1 gm per cubic centimeter "at temp of melting ice". Sensitive enough I have to close the laundry room doors to get it to stabilize.
(EDIT) Total cost ZERO dollars
(EDIT) Galileo and Faraday used "ghetto"equipment too, by today's standards
