If you are thinking of having a grade crossing, here is an easy way to make the lights flash. This is something I came up with some time ago as I needed a pair of flashing lights.
Great, thanks Shamus I have a grade crossing and a set of lights but was wondering of how I was going to make it all work, I am going to print it off and place it in a flie so when I come to that project I will make it. Again many thanks. Ron.
Thanks for the circuit Shamus. Where did you get the chip? is it a timer?
and instead of me trying to figure the value of the resistor could you tell us that too please.
Shamus has bet me to the posting. I have made many of these since I returned to model railroading. They are cheap to build and has many uses. One more thing Radio Shack has discontinued the chip that is being used. I baught 40 of them from all the Radio Shack's here in Wisconsin!
