    WATER LEVEL MONITOR FOR PUMPS

    You are way of; start reading up on things before you open up! There is NO arcing when the contacts are closing unless a. the voltage is high enough to jump across the contact pair before they are shut or b. the relay is stupidly under-dimensioned for the purpose! What you might se at the...

    help with solid state relay

    Hi keron, The circuit is not complete; here is how I've used the MOC3041 to switch a transformer. http://www.electronics-lab.com/projects/power/036/index.html The mains circuit part of this project should work for any inductive load.

    WATER LEVEL MONITOR FOR PUMPS

    Arcing is NOT caused by switching IN a load! Arcing is caused when opening the relay contacts (switching out a load)!

    need some inputs!!

    There could be a number of reasons for this! Have you got any pulses (on a scope) from U8:A clock? Also on pin 6 of U3:B input (from IC1)?

    Batteries In A Series

    Why burn away lots of energy from the poor batterys with a zener and a resistor, a terrible waste! Why not use a regulator and perhaps parallel some of the batterys for better efficiency?  ???

    Why is so hard to mimic the Knight Rider scanner Effect?

    We are not talking about the same things here, my practical experiences do not agree with your statements. You are also continuing to referee to certain commercial equipment with no relevance to what I have stated.                        I will not waste more time on this!

    Why is so hard to mimic the Knight Rider scanner Effect?

    Yes I know very well how a halogen works, thank you! This was not the point here; the point was the limited lifespan a halogen has in the suggested application. Unlike the police light (in the link you provided) the filaments in the knight rider application will have more time to
