Hey there, I'm working on designing a circuit which I wish to incorporate into my DeLorean.
I only need help with one aspect of this circuit. The conversion of a pulsed ON-OFF-ON-OFF (12V) signal into a constant ON signal (12V) whilst the ON-OFF-ON-OFF (12V) is continuing to happen, and then a constant OFF.
I found this solution on the web:
http://www.the12volt.com/relays/relaydiagram22.html
BUT, you can see that it requires a lot of capacitance there to hold on the 12V during the OFF part of the cycle. I was wondering if I could do the same thing with either a transistor or a SPST on IC in place of the automotive relay and therefore hopefully reduce the necessity for such a huge amount of capacitance. Can anyone give me a design, or help me put together one?
I was thinking something along the lines of this:
