Case and calibration procedure starting to take shape!

I’ve cadded the top of the case to fit into the bottom! You can see how there are there are two holes on the top for the OLED screen and the on/off button and a slot in the front for the sensor portion to come out. The current size is 32mm x 36mm x 88 mm. It’s a bit larger than I imagined it, but still easily handheld. I’m still working on the screw holes and nut retainers and polishing the case. I’m sure there will also be plenty more changes when I get the parts and find out how they all fit together.

Additionally, I’ve figured out how to easily calibrate the sensor. So basically, you first calibrate at 0 amps and turn the reference screw until the output is 0. Then you put a known current and tune the sensitivity screw until the read current is the known current (or the known current times a certain multiplier).
