High DC Current Sensing with a Raspberry Pi and Python

Do you want to measure high DC current (and 0–26V) using a raspberry pi or similar, inexpensively? 10 amps? 100 amps? Maybe 500A? Enough of the cheesy salesman talk.

My solution is to ‘hack’ an INA219 current sensor by removing (desoldering) the 0.1 Ohm resistor and ‘replacing’ it with a high-current shunt. Don’t worry, it’s not very difficult.
