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.A reader of the uC Hobby Blog writes:
Try stuffing the ball with crushed paper napkins(the cheaper you can get), they get rid of the “halo” on top of the ball.Link (Via MAKE)
