 I modified the TrainServos8.ino sketch in this thread on the Arduino forum. If you want a copy of my sketch, send me a PM.

  There is this one that I want to try that lets you control the speed of the servo. If you go the post #6 in this thread, it has a sketch for that. For this sketch, you'll need to include the "<VarSpeedServo.h>" in your libary to make it work.

 I also have 4 Tam Valley Octopus III's that are super nice for controlling servos and have a very nice speed.

Mine are about as noisy as the tortoise with 5 volts running the servos. I think it's more the servo than the PWM.


Thanks for all the info. The Tam Valley Octopus IIIs look like a suitable (i.e. lazy) option for me!

Thanks also for the 3D printing offer, unfortunately I don't have many photos of ex-SP switch and derail targets that are appropriate for my 1999 Tehachapi era. I will dig some up.

However, I think etched options will be more robust — I'm concerned about track cleaning and other logistics that will put these in peril!

This is a great thread, and really inspires me to try some more innovative switch/derail operations.

Your concern is well-placed. My proof-of-concept working mock-up met its demise at the business end of a vacuum cleaning wand.  :facepalm:
