So: Let's amp power from the line input (transistor), and feed that as the power supply to that RC circuit rising voltage

and a delayed buffer if we need more than 8bits to be read, to be read in sequence timedly the lowest and highest bits:

more accuracy and speed... requires external counter at userport then, like 10 MHz or more to do the thing..
Agemixer(05:30:12)
except that 1MHz divided by 256 (8 bits stages) gives only 4 kHz though. But if we are happy with, say, 6bits, then it is... 16 kHz samplerate
Agemixer(05:26:17)
it can't get more shrunk of a design, i guess
Agemixer(05:24:52)
only 1 transistor, 1 resistor, 2 caps, 1 opamp only
Agemixer(05:22:01)
REU might be good idea in that case, recording longer samples.
