The nano-amp-meter is here, pictures of unboxing and device. I tested, and referenced against a commercial nano-amp meter, it works, don't have time now to go deeper but it does work when connected to an oscilloscope for a good and accessible transient analysis. Pics/videos later in a split project.
I'll split this later as a separate project, I got way too much going on now. Also I need to clean up the design and add silk-screen, and make it more user friendly. Right now you need to really know what's going on to use it, might not be very useful for most people.
