A while ago I designed and built the Amazing $1 Short Circuit Finder with a resolution of 20 MicroOhms. This is one of my most popular videos to date. In later videos I further enhanced the Short Circuit finder with the help of some friends, and then I also built a surprisingly accurate MilliOhm meter. In this video I bring the two project together, test to see which one is the best at short circuit tracing, then attempt to go 20x further and build a MicroOhm meter with a resolution of just one Micro Ohm! Did it work? You just gotta press PLAY to find out!
