TL071 with a single supply: attempt #2

[ source ]

I setup the circuit in the bottom right, with a 5V supply though. A 500 mVpp sine wave at about 100 Hz was inputted with varying offset:

It appears that I was getting a gain of 1 (not expected.) The voltage scales get a bit confusing because the cables used on both of the channels had different impedance (10x vs 1x)

And here’s what the breadboard looked like:

This problem needs some more thinking (and datasheet reading!)
