Wow! This stuff is all awesome.  I just discovered the Wiimote project whilst on a quest to fins a way to enhance my lectures in class.  I just got a new LCD project and am looking for an affordable way to use powerpoint and still "write" out equations and notes. 
I love the wii whiteboard, and am already plotting mine.
Here is my question, and perhaps it's been raised somewhere here before:  is there someway to turn a wiimote into a notetaker digital pen?  These are digital pens that scribe whatever is written on paper onto a computer screen. 
A commercially available version of what I am talking about can be seen here:

Thanks for your help!

Easy:
1. Piggyback a ink pen to your ir pen
2. Secure a writting pad, the same realtive dimensions as your screen
3. Point your wiimote at the pad and calibrate the four cross hairs as the four corners of the pad.

Your away!

Oooo! Oooo! I have a question. I am working on building an IWB for my classroom to save thousands of dollars. I am wondering if I could tweak the info. above to build something else I saw a tech. convention. It was called different things but I would call it a type of slate. The teacher could walk around the room teaching and carry this slate with her/him and "write" on the board using a pen on the slate. How would you calibrate the pen without a projected image on the slate. I guess the big problem would be the wiimote "seeing" the pen and slate. Hmmm.

Use a clear clipboard.

attach wiimote  from the backside. so IR camera faces back side of clipboard It will read you IR pen perfectly

create some template rectangle  4 x 3 ratio

mark a dot 10% in and 10% down

90% in and 10% down

10% in and 90% down

90% in and 90% down

mark your 4 dots for 4 calibration points

print on overhead film

tape onto clipboard

I have created one and can walk around my room :)

Sorry I did not respond. I didn't realize you commented on my post about portable slate. Before I post pictures, I am going to need a little help. I can make it work pretty well but wiimote has to be about 2 feet away. Is there anyway to improve tracking when it is closer?

Hi,
When the Wiimote is close to the surface, the Wiimote will capture the reflected IR light too. Therefore, there will be issues of jumping cursors and also irregular tracking.

In Smoothboard, you can set the sensitivity lower to WiiLevel 1 or 2 if you are placing at a close distance.

Alternatively, you can also try to reduce the reflections present by checking with your mobile phone camera and adjusting your setup, or using a lower powered LED.

Regards,
Boon Jin

About the slate:

This is the Promethean ActivSlate (I think...or is it just called a slate?). It is a very cool tool, but it is awkward to write on. You have to hold the pen at just the right angle or it won't work. And, If I personally wanted a slate, I would get this: http://www.amazon.com/Wacom-Graphire-Bluetooth-8-Inch-Tablet/dp/B0009DG7KK

It is easier, you don't have to make it, and there is no need for a wiimote to be connected. Plus, you probably already have the bluetooth adaptor.

Hi!
A pic of my IR-pen, IR-spray can and the "wii-slate".



The "wii-slate" works but its a bit bulky  :'(
And like benpaddlejones told you- "Piggyback a ink pen to your ir-pen" is a must.

This is GOLD!

You could also setup outside screen toggle areas and have them mapped on your surface too.

Sorry to be a pain could you post some instructions and dimensions.

p.s. I reakon you could sell these, very professional looking.  ;D

Could you do something with a mirror at a 45 degree angle under the clipboard?
