If you are into building your own railroad, this instructable would help you design and improve, not to mention make a totally custom railway crossing set of lights. Improve upon any standard sign! Change the speed of the flash rate too!
I saw this: "Railway Crossing Lights" circuit and thought "I could make that!". I set up my breadboard. For details on how I setup a similar breadboard, see my other Instructables/JameCo Instructable here.
This project was fun, exciting, and frustrating....but what good project isn't? :)
Step 1: The Needed Parts
And since I didn't have a proper soldering gun stand, I made extra use with the CDROM case. Helped with my glue gun too :)
Step 2: Prepping to Circuit Board
Step 3: Prepping the Circuit Board
I split the trace with a gouge and then I started exposing copper so I can solder pad to.
The 555 time was only able to make use of 4 holes for its pins. I flattened out the other side and tinned them for soldering.
Step 4: The Hack Job
After everything was done, it wasn;t blinking. I knew it was a verrrry long blink rate but something wasn't right. Upon checking I noted that one of the sequences of resitor/wire/resistor was resistor/resistor/wire. Had to swap that. Luckily it was an easy fix.
Step 5: The End Result.
Thanks again Instructables and JameCo!
