FMJ, what value and power is your shunt resistor?
It is a 0,05 Ohm ceramic resistor. It is rated at 5W, not because that's necessary, but because it was easy and cheap to get on E-Bay.
You can also buy a 0,02 or 0,01 Ohm resistor. But because the normal current is so low, I decided to produce just a little bit more of heat in favor of a higher accuracy.
Will pick up this project again soon. At the moment about half of the circuitboard is assembled.
