Hi everyone,

I am new to this forum, i have tried to find an answer to my problem in vain ... Ive linked my wiimote to the computer with the bluetooth, but i have issues to calibrate the IR PEN.

When i "click" on the calibration points, nothing happen, but if put the IR PEN in front of the wiimote i can see the red point and it follows the movements of the IR PEN, so i guess the wiimote recognize it.

If i face the wiimote with the IR PEN and move it around the calibration points are validated, even if im not on it, but of course, it's almost impossible for me afterward to have a good control,  i move the IR PEN "in the air" and i see the mouse moving also but i can't be accurate this way, and if i turn back the IR PEN in front of the screen, with the LED touching it, it doesn't work anymore ...

My IR PEN is powered by 3 ag3 batteries and the led is 940nm, thank you in advance for your time if anyone has advices or a solution for it !

A couple things to check:

1.  Make sure you are using an Authentic Wii Remote.  Any fakes or third party brands have terrible ir camera sensitivity.  If you purchased a very cheap wii remote on ebay, then you most likely have a fake and this could be your issue.

2. Your infrared pen needs to be of high intensity.  The best is the Vishay TSAL 6400 infrared led.  If you are powering your ir pen with the AG3 batteries, I would recommend making sure you have fresh batteries.  Low battery life can be an issue...

3. Make sure that the wii remote can "see" the infrared light.  I have mine mounted on my ceiling slightly to the right of center.  This is because I am right handed and I angle my infrared pen slightly to the right when I write.  Either way, make sure that the infrared light is not being blocked by your hand or your body.  If you are relying on reflection, a smooth white surface works incredibly well.

Hope this helps and good luck!

Hello,

Thanx for your answer !

Since the day ive posted the message, i've tried to figure out if the problem comes from the wiimote or the irpen, this is what i've done :

Ive tried with my tv remote and my videoprojector remote instead of the irpen, in presenter mode, so i can see the red cross and the intensity of the signal, in both case, the red cross disappear once im like 8 feet away from it, or, when the infrared light does not face the wiimote (when it's turned back like if i wanted to write on the board) ... The intensity of the signal is the same when i use my irpen or both remotes, so i guess the problem is somewhere else.

I bought my wiimote as "refurbished" with a professional seller on ebay, it seems genuine because WII and Nintendo is written on it, the same was as an authentic model, so maybe the problem's there ?

Hope someone had a similar issue and can help me, thanx in advance !

Hey everybody,

Me again ... i sent back the refurbished wiimote i bought on ebay and got another one from a store, but it was a used one.
The same problem remain, i can't get more than 5% tracking utilization, very difficult to click on the 4 points, unless i point the infrared led pen in front of the wiimote ...

I bought an infrared pen from an official website in UK, i hope it will solve the problem, any suggestion is welcome.

Just to say that i fixed the problem, it was the led, i wasn't using a vishay model, now it's all good ! :)
