Yes. I fully understand. It is developing into the sort of thread in which I would be extremely interested in participating (were it not for the fact that I was already there).
It distinguishes itself from the standard "please do my school homework for me" type thread in that it looks at some interesting technology with a real, practical application.
But anyway, the only thing I would disagree with is this:
The raw TA12-100 would appear to deliver hefty negative voltages which are bad news for the standard ADC. These should be dealt with by one of a number of ways. One of which is to apply a DC bias voltage.
I'm also very interested in seeing how this progresses to the extent that I have added a couple of current transformers to my aliexpress shopping list.
