Ultra-precise milliOhm meter - Calibration and full assembly

This is probably my final video with this device because now I completed everything I wanted. In this video I show you the assembly process using a microscope camera, so you will see the soldering from a closer perspective. I decided to order more components and finish all four PCBs I had left after building the first device. I also did a "calibration" using a very precise 1 Ohm resistor. So now, as the instrument is "calibrated", it can be used with a higher confidence and credibility.



For more information on this project, check out my previous two videos in this series:

Part 1
