Rotating digital picture frame

Digital Picture Frames are finally coming down to tolerable prices and decent resolutions. We are about to give my mother one that's 1024x768 and 15" on the diagonal. In part that's because I never got around to building one out of a laptop though I still think a linux distro that turned an old laptop into a digital PF would be a great idea because the ability to do wireless networking to subscribe to flickr and other feeds is the waiting killer app for these frames. (Or frankly, I just want the wireless module for flat panel displays I have spoken of before.

However, turnkey appliances still have their attraction, and digital picture frames are one of the hot items for this year and probably a few to come.

However, one thing bothers me about them (and all other computer slide shows.) I take a modest number of photos in "portrait" mode, which is to say tilting the camera on its side to make a picture that is tall rather than wide. Of course I take many landscape too. And most digital picture frames are set up in landscape mode. When you see a portrait picture you lose half the resolution. You could get two frames -- one arranged in portrait mode and one in landscape, but I propose making a frame where the panel and frame have a small motor on them. Every so often the motor would rotate the frame 90 degrees, and the frame would then switch to doing the pictures that are right for that orientation, and later switch back.

You would want a silent motor of course. It need not be very fast, and you could blank the screen while it turns, or even put up a clever animation that itself counterspins around the axis point so it looks still. It would not work if you only had a very small number of portrait photos, but should be fine for most folks.

Slow, quiet stepper or servo motors are not very expensive, much cheaper than a second frame, though this does add moving parts.

I've wanted something similar as well for projected slide shows. There the motor could turn the internal panel, or perhaps just a mirror. If these things existed, people might take more portrait pictures. Today, seeing most photos on computer screens, there seems to be no reason to shoot portrait (other than to get a wider field of view.) If you will always view on the computer, shooting portrait -- for those who don't understand its value as a compositional tool -- may just seem like a waste. Now it would not be.


Just had the exact same idea so typed "rotating digital picture frame" into google and got this page.
Still can't find a manufacturer who makes them though :(

Brad, you have some errors in your blog code,
after posting I got this msg:

user warning: Unknown column 'style' in 'field list' query: SELECT scid, filter, style, effect, action FROM spam_custom WHERE effect != 4 in /home/brad/www/drupal/includes/ on line 172.

Also it didn't let me use the name "tony" but did not say why
