Ping pong ball LED diffuser

Picture 9-22


Note to self: ping pong balls make nice LED diffusers.

I tried sitting the ball on top of an LED, that did work but the brightness was greatly reduced. Next I tried drilling a small hole, just big enough for the LED. This works very well. There is a noticeable bright spot on the ball but in general the entire ball lights up well.

Try stuffing the ball with crushed paper napkins(the cheaper you can get), they get rid of the “halo” on top of the ball.
