I'm not sure whether this would best fit under Displays or General Hardware. Yesterday after work, I began looking for build logs of digital picture frames based on Linux. I found one good one from back in 2006, where the author posted all of the scripts he used to get it all to function. While the computer running it technically stays on all the time, he set it up to turn the display off at night and back on the next morning, or in an office environment, off when he got off work and back on again when he came in the next morning, leaving it off all weekend. Next, he set it up to store the necessary images in a photos folder and perform a check with a remote server every four hours, update it's image list and restart the slideshow.

I began testing my own last night. While the look of it is very crude, it works. Ubuntu 9.10 logs in automatically and launches the slideshow (Feh) application and rotates the images on a five minute interval. It uses a wireless connection to connect to my network and keeps itself in sync with a folder on my WHS. The second picture looks dark, but looks fine in person. I turned brightness and contrast down to 10%, which for general image viewing still looks fine when viewed more or less straight on.

I'm in the process of organizing hardware for the final setup. The test box is a 2.5GHz Celeron but with it being locked at 100x25, I can't underclock it. I want a slower fanless system. I'm looking at a Foxconn Atom 330 board, which will get 2GB of ram and either a notebook drive, an 8GB usb key or a Micro SD card alongside the wireless USB adapter. The flash drives would be silent and consume far less power than a notebook drive, but would a Micro SD card be fast enough to boot from? And how much wear and tear would I look forward to?

A class 6 microSDHC card would be fast enough to display the picture but might take a while to boot from considering you're planning on using Linux with a GUI.

I'd go for the 8GB Flash drive option if you can find one that has a decent transfer speeds.
