It seems a good idea, maybe I will use it to my projects.

Matt,

I am not sure which exact part number but I got my RGB LED from Alan Parekh’s store

Which RGB LED are you using? I live in the UK so don’t have the luxury of octopart but when ever I do searches on the internet etc. I always end up with SMD RGB LEDs and the one your using looks perfect for a project idea I have.

I just saw something similar:

Jamie Matthews uses an Arduino to make a glowing cube into a Physical Gmail Notifier.

I would think that lightly sanding the LED with 600 grit paper would fix the “halo” issue by diffusing the light emitted from the tip.

I wonder whether painting the tip of the LED opaque might stop the ‘halo effect’ on the far side of the ball, without creating a dark spot at the same time…?

Hotglue is a very good diffuser for LED’s

ops: and I cutted away the lens on the top of the led(s) with my dremel to assure a better light diffusion with no changes to the ball.

On the other hand, what about SMD leds for light diffusion inside of the ball?

I used acetone to remove logos and brands printed on the balls; use it carefully (or intentionally) as it solves the ball.

Styrofoam balls that you can get at crafts stores work even better. They diffuse light almost perfectly evenly. I used them with feathers and LEDs to make floating “fairies” for a Zelda themed room.
