Application - instrument panel lighting.
I have some led's of the right colour but they are normal ones that have a narrow angle. I'd like to have a more diffuse glow.
Filing the end of the led flat doesn't do much.
The next thing I was thinking of was drilling a bunch of holes in clear acrylic, inserting the led's, and roughenng the surface.
Doing all that is more work than typing, so in the sprit of looking for an alrady-invented wheel, does any know of a good method for diffusing the beam(s)?
