The foam is a good idea. I had to make this in short order out of supplies around the house and tried using some springy stuff for the wrist but it was hard to get a consistent movement, so just made it rigid. Not a new idea, I know, but had fun with it.

I saw a fun one a few years ago for the 4th of July.  It was a battery operated fan that would display animation of fireworks when the fan was running.  The fan blades were a flex circuit with RGB LEDs that produced the animation.  I wanted to say that it was a very cool toy, but that would be an awful pun even if it wasn't intended.

Saw it already on TV

This is definitely not new.

I saw it already on TV several years ago, possibly the "Gizmodo" gadget that someone else mentioned. It may have been a news item from a Consumer Electronics show at the time.

I remember that it was displaying messages from a keyboard buffer and the display was moving left and right on the tip of a large metronome.

My Kids had such a Toy

My kids had such a toy MANY years ago.  You swung this paddle shaped object back-and-forth and it displayed your keyed in text using LED's.  In the dark your eyes provided the persistence to make a stable image.


(My youngest is about to turn 39 years old... so this was quite a long time ago.)

Wrist strain?

Instead of pine, it might be better to use styrofoam. Seams the weight would waer on your wrist after a while. Another improment would be to use a spring steel joint between the handle and the "hand". That way, a little motion would set the hand into action with less strain on the wrist. Just a though for anyone concidering to build this.

I am still wondering what real purpose it is for?

Clever, but not a new idea.  I saw an LED message wand at Toys R Us many years ago.  The message was several inches high, and it included a built-in keyboard. 

You can buy a kit from Amazon for $23.74

Or a ready-made wand from Gizmodo  (from 2008)
