You may think now, i just ripped the idea here, but you're wrong. I wanted to do this since I saw this. The question was where to get a chumby, and where the display. Since I had a spare chumby for a while, tmbinc came up with the idea of recycling this into a chumby mod.
Since the manual of chumby's cpu prooved that 800 by 600 pixels is the maximum supported resolution, the only question left was how the housing should look like. I decided for the solution I first thought of. The ancient frame. Now watch the pictures for the rest of the story.
