[GreenKeys] Autostart

[Harold Hallikainen]

I've also designed and simulated a circuit that is loop powered. It
detects traffic on the loop, then holds the SSR for about a minute. I'll
post a link when I get home from dance camp.

designed a circuit. I might be able to find it.

72pt; } div.WordSection1 { page: WordSection1; }Well my idea is not to
do this 24x7, but just as a demo from time to time, but still without it
being powered on all the time.
