making a delay off timer | All About Circuits
The above timer I made works good for years now.
This is the situation
On the boat, you have a head (electric pump toilet).
I press a momentary switch that starts the timer circuit (runs 10 seconds) and the head empties itself in a Marine Sanitation Device called a Lectrasan.
The Lectrasan has a rotary timer switch. You turn it all the way round to activate the MSD Lectrasan.
Lectrasan has 2 mixer motors, 2 chambers divided by a titanium electrode assembly that has 20 amps DC running through it into the effluent water, it turns the water in hypochloric acid killing the bacteria. So first mixer runs and a few seconds later, other mixer runs and the electrode pack turns on for a minute, then the cycle ends, finished.
So it leaves the purified waste in the device till next flush of the head.
I would like to kick on the head flush again with my timer circuit activated to flush it out with clean water at the end of every Lectrasan cycle.
What is the easiest way to do that?
Is there a simple circuit that detects the motors stopping that can then trigger my timer circuit?
