Take care about the inductive part of your microohm-shunt.... this can result in some surprising measurements.... (t=L/R, so... if you expect something below 1uH you still have a long tau because R is very low too)
This is exactly the reason why i ask here!
Im not very used to work with inductor, so ill study the math these days.
I want to keep it as DIY as possible, as a student im pretty broke [emoji14]
Anyway, this is basically the circuit, ill just connect the shunt directly whitout using any switch.

http://www.eevblog.com/files/uCurrentRev5schematic.pdfAbout buying the resistors, are they better? Also, here is very important using 4 wire connection, any keyword to use?
If i choose to use the DIY shunt, any way to make it better about the inductance?
Like giving a u shaping to the resistor in order to cacel out the magnetic flux.
Some reference that i think are useful:
