Hi all,
I am using some small LEDs for a project, and the goal is to create a small light fixture. I am trying to find a good material to use to diffuse the light from the LEDs. I have looked at theatrical gel filters, but these are flimsy and impermanent. Is there a way to use a piece of Lexan and coat it with diffusion material? If so, what diffusion material would work best? Or is there some kind of plastic like Lexan that already has a suitable diffusion coating? Any help is greatly appreciated! Thanks!

I don't understand what's your goal, anyway I heard sometime solution base on optical-fibers. I can't help you further!

Biggest fault of Netduino? It runs by electricity.

Well, it mostly depends on the design, but you could also diffuse the LED with fine sandpaper, or use plexiglass - it is available with various textures, for example as replacement panels for fluorescent fixtures, or can be easily 'frosted' with sandpaper too.I am trying to find a good material to use to diffuse the light from the LEDs.

Cut off the top of the LED. See,

+1 on sandpaper, or use a defusing material such as a paper ball (probably not suited for this application).
