[...] all i need to know is basically what motors and chip would you guys suggest with controller? preferably a joystick of some sort.
also his camera is a nikon d7000 and doesnt have the capabilities of remote start/stop function on video so on this remote i want to put a small actuator of some sort to press the button, i looked around and couldnt find one small enough any suggestions on this project??
ok i need to move about 45 degrees a sec if possible but also have the possibility of going 3 degrees a sec, it has to be smooth starting and stopping.
the weight im not sure i will be building in a few weeks just kinda busy right now but my estimate with camera would be 3-7 pounds. and yes it is hanging just like in the picture i already made the crane,
and honestly about the controller just the cheapest joystick that will work with the system suggested really. its for my kid like i said before.
[...] and i need a solenoid to press the button which is 1/10 of an inch i would put the rig on but to add that to the controller would be great! again thanks for the speedy reply.
Hi,That sounds like a usable range.On broadcast equipment, you adjust such things as the speed of Pan/Tilt/Zoom functions on separate knobs and when activated, they pan (or whatever) at that speed and I think you should do it that way, as the pan and tilt will usually need different speeds for a smoothly flowing picture.Smooth starting and stopping is nice, but even without it, you usually film more than you need, to be able to select exactly where you should cut it afterward.Does he have the equipment for cutting/editing?
OK, for the tilt function, you should counter-balance the camera, or the motor will need all that more power.The weight in question is just what each motor will see. The tilt motor will move the camera and the release-contraption and the pan motor will see this plus the weight of the tilt-unit.With proper counter-balancing, you should be able to get the tilt motor to see less than 50g and the pan should hang in bearings, to minimize the force on the pan motor.Did you consider to add a remote zoom function?
You keep mentioning it's for a kid, but I wonder at what age the cheapest joysticks will do, while still being old enough to play with an expensive D7000? GrinIf you have a very old plain PC joystick (like from the eighties) lying around, that would do.Or you can get a thumb joystick for $4 at Sparkfun.
A micro servo will give a softer press than a solenoid.I'm not certain if we use the same terminology. When I say controller, I mean a microcontroller. To this comes motor drivers, as the controller cannot in itself drive a motor.The controller needs input from the "hand interface" (eg. joystick) and perhaps a couple of speed setting potentiometers.If needed, the joystick could be using a wireless link, but the speed settings are best placed on or near the controller, which in turn should go on the pan/tilt unit or the crane.Did you think about how he's gonna frame the shots?
so did you look at the links i posted? what did you think are they good enough?

like i said i posted two controllers did you see them ? what did you think?
if you think a cheaper controller wont work because of function then fine scratch it ill go with a 80 dollar controller lol it doesnt bother me i just want it to last and work especially if im putting this much time and money. and i also am asking because like i said before i dont want to buy the wrong thing and then it not be compatible or something.
i woud really like to talk to you offline to get specifics on the parts and what ill need for the tutorial. thanks soeren your amazing man i have learned alot in a very little bit of time.
Hi,Quote from: xkuco on July 25, 2011, 07:56:01 PM so did you look at the links i posted? what did you think are they good enough? The motor seems fine.The R/C transmitter will be very clumsy to use - the "joysticks" are single plane, i.e. one is up/down, the other is left/right and takes some time getting used to - a regular stick will be more "natural" to handle (if a stick is needed at all).The "2 Servo Joystick" is a servo controller with a joystick, not what you need, you just need the stick - if you do.This stick is from Servo City as well ($20) and should do fine (if you want a stick):(Click image for the product page).
I think we should eliminate a communication errors GrinThis is one example of a microcontroller, albeit a very small one:And this an example of a microcontroller board (plus a programmer and a couple of CD's with programming environment, datasheets and what not):In fact, this is the one I'd suggest - What's in the picture costs $50 (The programmer is $35 when bought separately).And you can get a packet with just one populated board plus two blank boards for $26 for your next projects,This will interface a joystick like the one I linked to, a couple of potentiometers (knobs), some switches and whatever else is needed to the motors driving the pan/tilt (and zoom) and still have resources left.Yes, it does mean that you have to learn a bit of programming, but that may easily turn into a father/son activity that others will envy (plus give you a few grey hairs when it behaves differently than you thought you asked it to Wink)
alright so i was looking at the joysticks and and im gonna go with this one
i really dont know anything about programming and making the whole setup. i just wanted to know as well if i get this set up will it be sensitive like for example when using the joystick if i move it a little itll go slow and if i go all the way it goes faster?? or do you have to program that?
also gears im using are these :
and do i need a speed controller???
and could i building something like this but adding the button to start/pause video??[Snip link]like buy the joy stick i was talking about and add my own servo controller and motor and then ike i sid will i need the speed controller ? because i would like to have joystick sensitivity ike i said in my other post.
hey man thanks for the info could you help me with this buying guide for the turtorial then with links ?? you can just send the links and ill write up the price and info for the people
i would like to bu that board and two dvd set dont know were to get it you didnt post a link and i know nothing about micro controllers im still reasearching.
[...] but if you think im not gonna complete this you have something coming for you man.
[....] im not one of these "regular beginners".
i respect your knowledge but dont respect that you assume.
i have heard of arduino what is the difference between that and a servo?
so your saying i can build this without a controller ??
and could i use the same stuff ??
i have heard of arduino what is the difference between that and a servo?
and what setup do you recommend if i can still use the same motors
