Hi all
Yep, did it by the book for those 8 mainline locations and it's worked well for ops sessions over about 7 years
However,
We've learned that switching my steel mill and related yard is too far to reach, but I was never willing to sink $$ into solution
Now, like you I have project to power 27 hard to reach single turnouts using Arduinos and SG90 servos. Have prototype working with a lot of cribbing from YouTube etc.
Haven't even tried to think how to interface with JMRI... But we have about 65 other hand thrown sites.
But am making panels with single pushbutton and bi-color LED indicators
In aiming for $5 per site and should be able to do that
Good luck and keep us posted on your progress.
