View Full Version : Need help with making radio needle move
06-20-2010, 09:47 PM
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.

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
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.
