I need to finish the thing!
Anyway, I tested the turn-on fix. It works with the AAA alkaline Energizers, at 5.1v total. (One mod: a Schottky barrier diode bypassing the resistor for turn-off.) I just bought some really crappy carbon-Zinc batteries and I will test it with them, too. If it works with those AAAs across a range of voltages, it should work with anything.
Now I have to worry about turn-off, which is slow because of the energy stored in the power-smoothing capacitors on the load side of the switch. I'm thinking that I should switch the LED power and the other power with separate devices. That's more circuit board space to take up.
And THEN I have to debug the detector (I've already got it built on the test article) and work on the pigeon-flasher.
And physical design, especially the layout of the input filter and the placement of the RJ-11 jack.
Gosh, I also have to test that other "works on polyethelene/polypropalene" glue. And thread the posts in the cases. And ....
Aaargh! I should keep a chart like I would on a software project so I'd know what to do when I was stalled on one thing or another.
Now back to the Chapter 4 revisions.
