Stan,
Yes, I was planning to do some more fiddling and would be happy to add your ideas, but GRJ will probably have it done and posted by the time I finish writing this... GRJ's design will probably be more compact and 'correct' as well.

I'm fast, but not that fast. However, I think this is fast enough.

Here's the "Stan0004" upgrade version.

Two level detection and indication.
Strain relief for battery connection.
Provision for external power switch.
Cap and diode to allow power from AC or DC sources.

Needless to say, the PCB got larger since this is an all thru-hole design, currently 1.15" x 2.35". I thought about making it for 1/8W resistors except for the LED's, but decided to stick with what I have using the 1/4W parts.
