looks like it needs an A/V part. maybe thats because it looks so much like a TV to me.
I'd buy one of these it looks pretty neat, but what would the price range be?
I dunno; maybe front me US$1,000 and I'll get started on it, then we'll see how it shakes out in the end.
Seriously, I'd love to tear into this project, but time and money are the biggest constraints. It shouldn't be too difficult a project for someone that's fairly adept with hand tools and maybe knows a good machinist. I've got no patents or copyrights on the design, so it's fair game!
