A two year project came to completion December 2010.
The signal is controlled by a fully programmed circuit board created just for that purpose. It sits in the limited space inside the top. No holes were drilled for on/off running as it is operated by a remote control which allows stopping, starting and separate operation of each feature; the arms without the lights, the lights without the arms, the amber light alone, the bell on or off and even “park” (both arms down and unit completely off). This video shows the signal with all its features concurrently activated.
Special thanks to Dale Mark and Ed Tapanes for all their information and very special thanks to John Long of Star Systems (sstec.com) without whose invaluable help, with the restoration (from day one) and the ultimate creation of the electronics, this project would never have been completed.
[Hopefully your computer can play this video at correct speed... but if not, I posted a second version which was taken with my iPhone and that will play properly. My laptop can play this version smoothly but not my desktop]
Yeah… I know… I need a new desktop computer !
