Turns out that a Ping Pong ball makes a reasonable LED diffuser. Just drill a hole and insert the LED. Easy micro Locnar! With an RBG LED this could make a nice system indicator. Maybe build a strip of these indicators to make several status indicators. Each server gets a mini orb to show it’s online status, maybe each email account. How about a ball of balls, each with an RGB LED…
I have wanted to build my own Locnar, like the one in the movie Heavy Metal, for some time now. I bought an Ambient Orb a few years ago and love it. I even bought the serial port adaptor for the Orb but never got around to doing anything with it. I just leave the Orb on my bookcase showing stock market performance, a lot of red lately. The other day I noticed a package of Ping Pong Balls. It struck me that they might make a nice diffuser for RGB LEDs. If they did work well, I could make a mini Ambient Orb or Locnar for my desk.
First, 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.
I have a ton of ideas on how to make use of this for monitoring status, much like the Ambient Orb does. Any suggestions?
