Model Forum / Radio Controlled / Air Models / March 2006Control servo with a joystick, hard wired?
I'm looking to make a camera control for a camera using some type of joystick. I've seen a few projects to make a servo driver but anyone have any ideas on how to make something with a joystick, just need two axis like a joystick. Thanks > I'm looking to make a camera control for a camera using some type of > joystick.

You'll need something to generate those pulses. The servo driver you have seen would be perfect. You replace the control stick potentiometers, assuming it utilizes pots, in place of the pots that control the driver. Frankly, you can buy a two-channel 75 MHz complete radio control system for less than $50 these days. I would think that this would be a more convenient, reliable and cheaper alternative to doing it the hard way. Ed Cregger Thanks, I'm try to build an ROV of sorts and need it to be wired. I'll see what I can find >Thanks, I'm try to build an ROV of sorts and need it to be wired.

Thanks If you're willing to build a circuit check on sci.electronics.basic or sci.electronic.design. This can be handled easily by a pair of 555 timers, with various enhancements that could be done if you're in the mood for it.

( a .15 cent diode saves an hours work building another.) regards Alan T.
