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.

I present here a Parallax Propeller WiiMote WhiteBoard.
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.
Any colour can be used - this is an idea of the palette spectrum.
Its not limited to just drawing.......why not predraw buttons and slider etcetc and use the IR pen press the virtual buttons and control motors and servos and...and..and.
BTW :- its not limited to a small screen - it can be scaled up to Johnny Chung Lee style "Beamer"
