Hi there, so I'm trying to make an old 50's radio tuner needle to pan sporadically but looped to run continuously. I included a picture of the radio. The radio is gonna be part of my costume, running off a car battery for leds, audio and the motor for the needle. My question is where can I get a cheap controller and servo and how can I program it to achieve this effect. I have ZERO experience when it comes to controllers so I am looking for something easy to program and setup also would be great if someone could step me thorough this if possible.

Thank You!

What you want to do is actually super easy.
I recommend you get in contact with EFX tech

Go with a prop 1 controller and a servo from
www.servocity.com
They can walk you through it and most ikely help you with/do the programming on the controller.

If you've got more money to throw around ($109 plus shipping), servocity also has this servo recorder (http://www.servocity.com/html/servo_recorder_playback_contro.html). Using it is as simple as

Push slider to "Record"
Twist knob back and forth for a while
Push slider to "Loop"

Then it'll continuously loop whatever you did in step 2, for up to 4 servos.
