I didn't want to buy CurrentRanger since it violates Dave's CC-BY-SA license but tinyCurrent seems good enough for my purposes. Well, not so much after shipping and my bank's $25 WIRE TRANSFER FEE, so about $140 total USD. I see n-fuse has an
eBay store where I can pay with whatever for about $130, after currency conversion.
At over $100, I could just get a Power Profiler II with nice software if I don't need to measure under 100nA.
That said, tinyCurrent is open source. Has anyone successfully built it? Not sure how much soldering skill is required for a sensitive measurement tool, or how to calibrate and I don't have a reflow oven.
The img tag doesn't work for me so I edited to upload the screenshot instead.
