The number of inputs from TechSmith is being throttled by YouTube. They're working on that too.
Updated photos of the two Raspberry Pi configurations and custom boards. Not happy with these photos or camera either.
This photo illustrates why all the effort to get two unicorn boards to work together. I have received about a third of the semaphores needed. Others have been backordered for months. Now with coronavirus, who knows when. In the meantime, LEDs will have to do.
Each colored dot (tri-color LED) represents the aspect of a semaphore arm. See similar diagram in "Pictures."
The white dots are washed out "yellow." Even in person, the red/green don't blind to make a very good yellow.
Space on the left will be used to show the CPU temperature and fan state.
