The thing is, looking back on this thread, it originated in 2003.. it's now 2006 and Bruce has not added any comments since April of this year... so the book may be a long time in coming ???
I think that we are talking about the same thing. I didn't mention nor imply anything complicated. Unless you consider a logarithmic type of sensor, which are simple to connect, but a quick search on this forum shows no results on how to implement the conversion in code.

I would also like to add power supplies, since every project needs one.
