[align=left]I have finally finnished the toprig for my 17 meter mast.
I wanted to get rid of any cables so I used 30 mm square tubes and hollow plastic corner pieces.
I used 2 Hitech HS-475HB servo,s (Pan-one converted to 360 degrees) ,gentleds for the remote shutter and zoom, a 2.4 Ghz 200 MW video downlink from Black Widow AV and a Multiplex Picoline 6 channel radiotransmitter with a 6 channel reciever to control the toprig and camera.
It works great and can be controlled from more then 300ft distance(nice when it is cold outside).
P.S not suitable for KAP because of weight:sad1050 grams with batteries,without camera).

I am fascinated!!!I thought I was a pretty good DIY'er but you lost me.

Would you translate your pan and tilt mechanism.

I set my camera up and focus on a bird's nest and wait. Would love to have zoom, pan and tilt and wireless video feedback for a FZ30. Have wired video to hand held television and wireless shutter release. But that's it. I'm envious.

Thanks

Stan

his tilt and pan are done by using servos

look in the pic of the rig in the case....the right hand pivot for tilt is direct into a servo and u can see the other servo underneath in the center

servos are geared small motors that u can control via remote

u can only control the zoom and shutter via the infa red leds if your camera support infa red remote control anyway

I made a gimbel mounted coffee cup holder some time ago.

So what you did is to add servos to the vertical and horizontal axises. Are the servos directly coupled to the axle or did you gear down the motor?

I have already Googled all the terms in your post. There are a lot of details that I do not understand yet.

I have my DIYwireless remote shutter release for my camera. May have to servo the zoom ring. Of course add a video downlink.

Good winter project.

Thanks for the help and info!

servos have a pretty slow turn.......all the gears are inside so u get a slow powerfull turn, speaking for how i did it one side of a pivot is just normal the other side as a servo mounted so its shaft is inline and a screw direct into it make the pivot complete. i also have a servo modified to turn 360 but that is a top pivot whats bolted through for safety.

if u look at kamilahjans pics u will see at the bottom a servo that as a small cog on it.......bear in mind most of his servo is hidden in the box section tube...and it attaches to a shot pole with a larger cog that looks a bit like bottom of a ski pole

my rig for kite is in a thread in this section....it also mounts on a pole too and is very lightweight

[align=left]hi Stan

For the tilt function i used a servo shaft adaptor mounted straight on the servo and the other side to the 30 mm square tubing( Like reanimator said 3/4 of the servo is inside the tubing).

http://www.servocity.com/html/servo_shaft_adaptors.html

For the passive side of the tilt function i used 2 mounting hubs and a hollow aluminium tube for the cables and wires.

http://www.servocity.com/html/alumin...ting_hubs.html

The pan function is done with a modified(360 degree) servo, a metal servo gear and a aluminium hub mounted gear.
I used the hub mounted gear to slow down the pan function and for a better control of the pan function.

http://www.servocity.com/html/48p_al...hub_gears.html

For the wireless video signal i used the 2.4 Ghz 200 mw transmitter/reciever set from Black Widow AV.

http://www.blackwidowav.com/products24ghz.html

This should work for the FZ30 also, TIP!!!...the transmitter works better on 6 V then on 4.8 V.

The servo conrolled zoom is done before so it can work........maybe with the help of a chain???

Good luck with your winter project

How much rotation and tilt would you say it has? I know a little about servos they move from about 7:00 around to about 5:00 not all the way around.

style="BACKGROUND-COLOR: #000000"

style="BACKGROUND-COLOR: #000000"How did you settle on the gearing? why the little one on the servo? does the sound of the servos scare the animals?

[align=left]Hi

The pan function is endless because of the 360 modification and the tilt is about 120 degrees(but you can modify that one also if you want)
Here,s a link to how to convert to 360(endless) rotation.

http://www.kaper.us/basics/Bas_360_R.html

I mounted the little gear on the servo because it is the most convenient, you can not mount the little gear on an axel.
the big gear is mounted on a hub and then mounted on an axel.

The servo,s might scare away animals, i don,t know, I am not using the rig for wildlife photography. just for PAP and panorama,s.

Very nice. Much more elegant than my modified Brooxes rig. Have you taken many pictures? The G6 was absolutely made for this sort of shooting. Plus, it takes beautiful pictures as long as you have plenty of light.
