That was a misfired post, was supposed to send to the fellow doing processor current sensing... sorrysorry --- End quote --- LOL ok, no worries. I was so confused, couldn't make sense of any of that in relation to anything I had posted, and just some of the stuff was generally over my head. |

..thanks for overlooking, That other subject, was involving the lowest ranges, in a typ DMM. Just that measuring low current, it's better, somewhat, to stick a half-ohm resistor in series, and read the voltage, but meters generally only go down to, like 00.1 on the mV scale, so that 100 uV you see in the read out is getting rock bottom...

Just posted up Part 4 of the build, it's coming together, starting to actually take shape :) https://youtu.be/xCvjLrztIIU |
