Make your own flasher unit

[shamus]

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 bet me to the posting!

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!
