uIECC

What is an IECC? See Integrated Electronic Control Centre on Wikipedia.

I'm a long-time member of the South Cheshire Model Engineering Society (SCMES) and the track at the site itself is equipped with 3-aspect LED signals. Unfortunately the member who was originally developing the system died in a car accident, so the system remained unfinished for a long time.

The only major component in the system missing was the central controller, and I attempted to build a controller, complete with custom circuit boards to control an expandable number of signals.

It was never completed, as a combination of university work, my PhD, and my distance from the SCMES site got in the way of completion, and later, several other members built another system to do the same.

Still, it was an interesting experiment in RS485 signalling for communicating with a bunch of slave boards.
