I would like to thank everone at RCS64 and also everyone involved in the arduino project for flashing yellow lights, green lights, and start gantry. Earlier this year I finally got around to installing them on my track and I love it. Well done to everyone involved.
Here are a (poor quality) video showing it in action on my track
