I'm trying an update of my Rivercam project ( http://www.picaxeforum.co.uk/showthread.php?13705-Rivercam-with-PICAXE-pan-tilt-control ) with a better camera and zoom. Unfortunately I'm finding with the heavier camera that there is jitter every few seconds when the tilt servo is outside of the range of about 145-155--I think because the weight of the camera. I've got it about as well balanced as I can front to back.
I'm using Hitec 322 servos. I tried a Hitec 422 but it was worse (not surprising--45.8 oz-in compared to 51 for the 322). Pan is stable.
I've done a lot of things to try to get rid of jitter from various sources, including serin commands, which I've replaced with hserin. I don't need very much tilt range--130 to 170 would probably be fine. I'm using sevropos after an initial servo command, and am moving one step at a time from one input point-of-focus to another. That goes smoothly.
Can anyone recommend a servo with better holding power? Or some other solution to my problem?
Edit: Running with 5 volts--would I do better with 6?
