Re: New lightweight motorized panorama head

...but what advantage gives a motorized head in speed-mode when you need to shoot lots of more images - which takes more time?? None. :cool: Klaus, 4 images or 8 images, the time for a fast rotation is the same, it doesn't take more time. The only thing that changes is the number of images you capt...

Re: New lightweight motorized panorama head

For very sharp photos with a fisheye on a 3-sec rotation you need a shutter speed of 1/1500. With ISO 400 and f5.6 you're ok on an outdoors scene, in some cases you can go to f8. The trick to avoid ghosts on a fast rotation is to shoot more images than you actually need. So, if you need 4 images, sh...

Re: New lightweight motorized panorama head

Here's some photos of the final version of the motorized head.
Reduced the size of the controller quite a bit.
Total weight including batteries and controller: 920gr

Also improved the timelapse function to be much smoother:

The Theta is an interesting device and maybe it even deserves its own forum thread ;) It lacks any kind of manual exposure controls It produces perfectly stitched, 3584 x 1792 equirectangular images The fisheye lenses are 0.75mm (6mm equivalent) Quality varies wildly depending on lighting. The sampl...

Klaus, have you actually shot a pano with a 8mm fisheye lens on a 2.5-3sec continuous rotation? In my tests it looked pretty sharp, I'll repeat the test this coming week with the final version of the prototype and will upload the pano. The point is to be able to capture fast action and street panos ...

Yeps, so am I.....is use an LCD and that takes up 12 connections, 2 Big Easy controllers eating 3 a piece, a 335 accelerometer using up 5 more of which 3 are analog pins (of course) and I also build a 5 switch resistor cascade on it....and an optocoupler (running on 3.3 volts) The whole system runs...

Applaus looks great.....I've build a custom shield on my Ardiuno Uno (using a Arduino prototype board and a lot of tight nook and cranny soldering (since the prototype board contains a lot of solitairy islands so is not so ideal for prototyping)....In the final version (using a 3D printed casing th...

Acceleration & deceleration are essential. I use it too and as a matter of fact it's one of the parameters the user can customize. Backlash is not a problem, I'm using the controller to hold it in place when not shooting. I was a little concerned about power draw but I let it run continuously to tes...

It seems to work well with the Gobi head. It uses a standard 1/4"-20 screw so it works with just about any head. In the monopod video I used a panoramic bracket I made that's very light (see attached photo) I guess if someone wanted a cheap option for a full sphere, they could tilt the head down an...

Thanks. I made it lightweight so it can be used on a pole (hence the remote release) and also to be able to shoot panos using a monopod rather than having to carry a tripod. It can shoot a 360 pano in 2.5 sec. Here's a video using it on a monopod: http://www.youtube.com/watch?v=_bVY1fkoryI That's an...

New lightweight motorized panorama head

Here's a lightweight, single-row, motorized head I made, weight with batteries and controller is about 900gr. It's user-programmable, can be used on a monopod for fast action panos and it can be triggered via remote. You can see it in action here: http://www.youtube.com/watch?v=vGSNLAhMVj0
