Semaphore done..Now to automate

This week I was only able to finalise the semaphore. This entailed mostly painting in the wires. Today I bodgied up a jig from some ply offcuts for putting the semaphore in as well as holding the servo to automate the arm.

Below are the photos promised in the last post as well as what has been done this week.

This week I will probably only be doing the automation. Instead of the MERG module to automate, I might bung up on the breadboard a servo controller articulated in the latest MERG newsletter to see how it goes. If it doesn't the MERG module will be Plan B!

I could have used a smaller diameter drill in hindsight.

Sorry the original is portrait but no idea why this
isn't!
