Ultra-precise milliOhm meter - Calibration and full assembly

Check out PCBWay's website for rapid prototyping of printed circuit boards, CNC and 3D printing services and many more! https://www.pcbway.com/setinvite.aspx...

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.

The circuit is based on the designs published by
‪@scullcomhobbyelectronics1702‬: a milliOhm meter and for a 6½-digit voltmeter. I "alloyed" these two project into one, designed my own PCB, then built the circuit.
