Not sure what this has to do with the Train Thing, but I spent most of the week playing working with the Unicorn HAT(s) for the Raspberry Pi. Working with the examples provided by Pimoroni in https://github.com/pimoroni/unicorn-hat-hd/blob/master/examples/ubercorn-rainbow-2x1.py one used two Unicorns side by side. How could I resist? Well the example didn't work with just one Unicorn HD HAT so I built the interface/cables to hook-up two. Still does not work. Their forum has not provided an answer, yet. It is thanksgiving week. I am sure I can make this related, so the documentation is included. Multi-forum helps posted.


The last hardware to be built (except for semaphores) was the tri-light parking lot signals Seen installed here.


This completes Phase I of the project.


The hardware is finished, with the exception of designing/building/installing of the servo controls and semaphores, in phase III.
