How about a 12v hobby store solenoid, you mount it horizontal, attach to the mass to be measured and then power it with a constant current. Use an opto sensor and PIC to time the pull-in time. Have it returned by spring and do a few pull-tests before the mass calc. Presto, kitchen scales that measures mass. Perfect for taking to your next zero-G cooking class. :o) -Roman > > A competition?
