Jurek and the Amazing Techno, Colored DreamWall

Jurek and the Amazing Techno, Colored DreamWall

The title is mostly a placeholder, as I haven't really figured out a name for it yet. This project is a wall hanging that consists of semi-large triangular pixels using discrete RGB LED's and PWM to control intensity levels of each LED, resulting in a 4096-color display.

New Space pictures

Work Space
I finally got some pictures taken of the new space. I haven't been working on the wall, really, although tonight, I layed it on the saw horses and opened it up to double-check things.

I got a dividing/pegboard storage wall built last Monday, so I finally have someplace other than the floor to store my tools.
Tonight, I also cobbled together some overhead storage for wood, so I can keep stuff out of the way a little bit better. I don't have any pictures of that, but it's pretty basic. I made it out of a single 8' 2x4, so it's obviously not too complicated.

Anywho... here're the pictures. I didn't get a shot of the table saw, for some reason, but you probably get the idea. It's basically just to the left of the 4th picture, straight back from the white bucket in the corner.

Design & Planning
I started thinking about different ways to make smaller versions of the wall for cheap. I can use just a single driver board to make a smaller 20-pixel or even 15- or 10-pixel piece (or anything under 20, I guess, really).
I can make a nice O shape with 18 pixels (the center 6 forming a hexagon, missing), but construction might be an issue. T'wood certainly be something to have fabricated for me.

The other issue would be the processor. I've briefly started looking at other Atmel processors that are in a DIP package, and there are several (too many, it seems) available. If I would make something cheaper, the goal would be to make it as simple as possible, and computer interface (real-time, anyway) would not be a feature of it. Also, I would have to make it power-friendly enough so that a wall wart adapter could work.

Even if I use the same processor I did for the big wall (which probably costs ~$50-75 in parts, currently), I could probably get the cost down to maybe $1000 for the small 18-pixel O shape.

Anyone have any comments or ideas? I'd be glad to hear them.
