[Windell] from Evil Mad Scientist Laboratories took one of their Peggy 2 kits and gave it a little upgrade. The Peggy 2 is a programmable 25×25 LED display. It’s Arduino compatible and can accommodate big 10mm LEDs. Most people assemble them using just one color, but [Windell] decided to create giant RGB pixels by placing discrete red, green, blue, and white LEDs next to each other in the board. This creates a 12.5×12.5 grid of full color pixels. It’s an interesting effect and you should definitely check out the video embedded below which shows how the transition can be smoothed using a diffuser.

Wow, that’s really cool. U should try and patent some part of that quick…it has some real world economic value right now. I think of the light canopy in Las Vegas off the top of my head.
I think its already patented by Daktronics they do LED based large area displays.
Im pretty sure they acually use this… like alot… im on my macbook, and when i took a macro shot of my screen and zoomed in a bunch, there were bajillions of rows of these tiny stacks of the lights: red, blue, and green. Idk
I’m not sure whether the previous posters are being sarcastic, or if they really are that incompetent. I’d like to assume humour over stupidity, but this IS the internet after all.
awesome colour transition. Yea hopefully they are sarcastic. Otherwise mankind is in trouble.
Don’t be so harsh, there’s a beggining in every being. If they’re interested, then it’s good.
Cool effect =D… practical? dunno, but its cool =D.
That guy has the most soothing voice. I expect him to be telling me to just breath in and relax.
That is some heavy duty diffusion. The key there is those are fairly wide-angle LEDs.
Any narrow LED will just make a spot on diffusion, period. I just built a project for a model box with some dimmed LEDs to simulate a larger-scale diffused glowing box thing. Theatrical diffusion (a reasonably heavy one, rosco 100) didn’t do shit to my last-minute narrow-angle LEDs
that diffuser looks great. diffusion’s been doing my head in for months. are there specific plastics you can get stuff made out of that do this better?
That’s pretty cool, and the diffuser panel was impressive!
I was never a programmer, but I imagine projects like these are a great way to get started.
Likewise for programmers who don’t do a lot of hardware!
Pretty nice effect, and it explains why sony and such companies are saying there will be large screen OLED displays later in 2010, they hope some hacker makes them and they can then re-sell them branded as sony :)

You could always sand the top… carefully. That will add a diffusion and widen the spread at the same time.
