Parallax Propeller/WiiMote White Board
I have been a fan of Johnny Chung Lees work with the Wiimote camera for a long time now ....
... (its always/always roaming in the back of my mind)
.... during my experimentation with the "Lassiter" i had one of those wait a "MoMo" moments .................
Thats when the fun began and some simple modifications turned out into a Virtual White Board.

The Wiimote can track InfraRed Light, i have made an IR pen from an IR LED with resister through a switch to a 3V battery supply.
By pointing a wiimote at a LCD display, you can create very low-cost interactive whiteboards or tablet displays.
Since the Wiimote can track 4 points, up to 4 pens can be used simultaneously .
It can also be used with rear-projected displays ie Beamers for extra fun and immersion.
My system uses a Parallax Propeller chip programmed in spin.......
..... the Key to the whole idea is a simple Hacked WiiMote Camera tracking an InfraRed Blob of light.

Here is the Physical InfraRed Pen used for the Virtual Painting
Its basically 3V battery connected through a switch and resistor.

Here you can see my virtual screen reset buttons.
You can have as many as you want, any size/shape and wherever you want.

BTW :- its not limited to a small screen - it can be scaled up to Johnny Chung Lee style "Beamer"

I have often dipped into hack-a-day when i was researching wii-bluetooth links ... (the project is so much easier without bluetooth)
