¡Hola buenas tardes Paul! As a first attempt, I think very well done indeed. On my own layout, I have been scratch building some early era two-aspect colour lights but, for a proposed addition branch line, I will be looking at using semaphore signals and operating them via rods, from servos, and using LEDs to light them. Your videos has been extremely useful. One question, where did you source the SML? Un saludo. Gary
Have you thought about using cmri/JMRI to get the arms automated? There are good tutorials on Little Wicket you tube site. I have done the older metal signals this way, and was thinking about what you have done, but I think it may be too fiddly for me. Great tutorial though. Thanks for uploading.
