Hello,
I am using a macbook with Uwe Schmidt's application.  I have tried to place my wiimote in many different areas and distances from my projector screen but it doesn't let me use my ir pen correctly.
My computer is set up to Mirror the desktop since I don't want to be dragging my applications to the right to show whats on my screen all the time.  I am using Streamlight 65089 Stylus 6-1/4-Inch Penlight Combo, Infrared LED from Amazon with pens on order from John Mitchell.  I get the program to find my wiimote, I go to calibrate the screen and at times it as I am getting on a chair (tall screen) to touch the first area it turns into a green check mark.  I started kind of playing around with it and could actually move the cursor by pointing my pen at the wiimote, is that suppose to happen?  It's like somehow reversed since I would like it to work when I am pointing my pen or touching my pen to the screen.
Any advice it welcomed!

Beth

The issue is with your Ir-Pen. Sounds like the IR-Led is not up to the job. This pen has two modes from memory (Switch on/off & Momentary Switch, on end of pen). You need to make sure you are using the momentary switch not leaving the pen always on.

The Wiimote IWB works by sending a cursor message to the location at which the IR-Blob is detected. Hence if you have the IR-Led 'on' then the cursor will just trace.

You need to point the IR_pen to the Wiimote because the IR-Led is too week and does not create a strong enough IR-Source for the Wiimote to detect.

I suggest you search through the forum and find a pen retailer who uses the Vishay TSAL6400 IR-led with a better located momentary switch. This will fix your problems.

Is there something other than the program that I should download?  I got the pens, made sure they had batteries in them and all of that, got the program to see my wiimote and it's still a 60/40 chance that I can calibrate the board and then once I get it calibrated I still can't open anything.  Is there something else other than the whiteboard application that I should have installed on my computer? 

Beth

These are the pens I ordered.

I've just started working/playing with the Wiimote Whiteboard this week. We are using IR LEDs from Radio Shack* and hand built pens. I'm finding that having the LED on the back rather than against the board works much better. Also, we've been putting our Wiimote next to or on top of the projector so that makes seeing a light pressed against the board even harder.

*The specs on the bags claim these LEDs are
Radiant Power: 16mW
Forward Voltage: 1.2V
Forward Current: 100ma
1/2 Angle: 45
Wavelength: 940nm

You will find the IR-Led on the back of the pen causes problems when writing and is highly dependant on your position. The Vishay TSAL6400 is strong enoug that it can be used on the tip of the pen and is far more functional.
