This sounds like something I could use....

I wouldn't mind replacing the old analog current / volt meter in my 30amp load tester with a digital version, including aHr Capacity.

The current shunt we have produces 50mv max at full load (50amp)

How could this be measured using a pic.. (Use op amp???) of sort?

I would like to know if anyone else has done this before.

On an other topic, has anybody made their own wire wound resistors before?

Cheers
