I'm looking for this set : PT785-S. ( http://www.servocity.com/html/pt785-s_pan___tilt_system.html ) It's a pan and tilt system, i will control it with an arduino.
The thing is that servocity seems to stop to sell this kit, and have a new one who is more more expensive ( because they had joystick controller, ...). But i only need the basic system.
My question is : Is there someone who know where i can have one ? If it's a second hand i'm interested too !
Or maybe, someone know a better system ? I cannot put a lot of money on it because i'm student.
I want to plug a DSLR camera on it ( about 1kg ) so maybe the SPT200 from servocity can handle it. Does someone have an experience on it ?
Thanks a lot

Oh I see, i'll have to look into that, my cannon has the auto feature but i've been having to do it manually through dragon frame peripherals. maybe i've got it on manual instead of auto? unsure.
Cheers for the tip tho
just replied to your PM too Pete
I made a mistake when i ask you about the focus. I will probably let the focus on manual to prevent flickering.
My question was more about motorized the zoom for a lens (changing the focal length) ? Is it possible to do it simply ?
I should be paying you - thanks for the props!

I'd echo what Pete said here- I bought a TB3 too- and have driven a slider with the spare port successfully- it was used on a 4 week project for Lego to great success, and was reliable accurate and for our purposes repeatable. I've also experimented with it to produce a few time lapse sequences, which are equally interesting , and for the stop motion addict, curiously liberating-(find scene, set time, shoot)
somehow seems too easy!
For my money, this is a great product and the best option currently for a budget pan/tilt/ track combo...I'd also agree that Brian - the emotimo head honcho- has been very forthcoming and supportive.
No, he's not paying me- I'm just saying- credit where due.
As follow on to the discussion and questions about servos heads - definitely not repeatable which is confusing as servos generally are position sensitive. Hobby servos do have position feedback when they are unmodified - this comes from a built in potentiometer that gives feedback between 0 and about 270 degrees - at that point, the potentiometer has mechanical stops and can't turn anymore. You can modify servos to remove these stops and the position feedback to make them into inexpensive gear motors. These have great torque, decent speed, but alas, no more position feedback since the potentiometer doesn't change anymore. So long story short - these heads are great for video, but won't give you any ability to repeat a shot or go to a specific position.
Hope this helps and thanks for being such great customers of eMotimo!
Thanks you for the explanation about servo, i will definitly not take this option and look forward to buy one of your TB3 :)
