Well the digital picture frame has been on my wall now for little more than a month, and humming along not so silently. The stock fan on the heatsink I decided to use was really annoying me so I took it off and replaced it with a bigger, slower quieter one. While it was off of the wall I thought I should document the innards for posterity.
The original hard drive idea of using a laptop drive died somewhere in my get it done frenzy, and really should be revisited, as I don't like the overall layout when the full side Hard disk is in.
I had to add a slim usb pci card because the onboard usb 1.0 header, is giving me a some servious trouble. The header layout is not well documented, so I cannot tell which pin is one, and only has six pins instead of the normal seven (8 with 1 not in use for a "key") The provided cable is not terminated on both sides, just one so I would have to crimp, or solder the other end.
The wireless ps/2 mouse/keyboard I am using seems to pick up some kind of signal makes the pc think the mouse is being moved. This is not convienient when you are using a screen saver as your "picture frame". As a fix I disconnected the mouse part of the wireless keyboard mouse hookup.
Ordinarily this setup would not even need to have a keyboard/mouse at all, but I have a FON router, I have to logon before the computer can access the internet. Kind of tedious, but the movement is worth a little suffering.
