DIY conductivity meter
I just thought you guys might get a kick out of this thing I made a few years back. It measures the salt level in your tank through electrical conductivity. It requires you to mix up a solution to "calibrate" it and I don't even have time to post the instructions right now but this post is to remind me to do it when I get home. It's a fun little project.
