Wheatstone Bridge Hydrometer

So I was not making the wheatstone bridge for my health. My intent was to build a hydrometer for home brewing. There are multiple ways of doing this but I wanted to play around with the strain gages. The principle being the buoyancy of a ping pong ball bolted at the end of a beam would vary as a function of a fluids density or Specific Gravity which is the typical measurement when home brewing.

This was my crude build and attempt at utilizing it as such but was not overall pleased with the results, fun idea. I had a few other ideas for making a hydrometer but ditched them because of cost and complexity to replace a simple glass tube.
