Hi, Ian Paisley has a site with lots of circuits like you need.

His stuff is a lot of model trains, and for turning lights on and off and timing with 555's, can't be beat.
And, I found my solution.
The output is not the same, but by adding the 0.1uF cap. and the 2 39k resistors on the input I am able to keep the 555 from triggering twice, when fed by a continuous signal.
Thank You Delphi Forum!
I need a short-duration timer for my chicken feeder.
I have a 120V. solenoid that when powered pulls open a slide and allows chicken feed to flow through a pipe to scatter about the coop. The power comes from a mechanical timer with a 15-min. minimum range. I don't want the solenoid to be...
