Work continues here on milton, start and stop a lot because of the
season. 2 nagging questions are pestering me, for Peter or anyone else
with ideas.

1. I started stuffing the bank boards. I'm a bit unclear on the values
for R1 and R2 - not knowing how to apply ohm's law to my situation,
maybe someone can tell me the values to use. I'll be using a 15v power
supply - will 330 ohm for R1 and 1K ohm for R2 yield a 0-8 volt
output? If not, what values should I use? And what if I wanted a 0-4
volt output - I thought it might be useful to have one of the banks
with a narrower but more precise range.

2. The J1, J2 and J3 connectors - does anyone have specific parts
numbers for solutions for these that worked? I keep ordering
experimental parts, but haven't been satisfied with anything I've
gotten yet. Both the plugs and the connecting cables are what I'm
looking for. I may have just answered my own question by opening my
digikey catalog, but I'd still be interested in hearing your solutions.

Thanks!

Steve Drake

R2 is 1k. R1 - 330 ohm is fine. the output is more governed by the value of the 430K in the feedback. You may need to play around with this. 470K to 510K ...
