hey, did anybody tried this on?
http://www.laantec.de/product_info.php?products_id=15505
english: http://store.greenpearle.com/infiniterlr1.html
the problem is, that i had to remove the ir filter, to get my normal laserpointer to work.
so i thought, in a room where the light is on, its more easy to use ir :)
another problem is, that my lcd tv swollows the laserpointer, the wiimote does not see enough from the laserpointer... what about beamers? does it work better then lcd tv's?

ill give you some feedback how thr ir+laserpointer works :)

As far as I can tell thats a TV remote and laser pointer put into a single package, and nothing more.

sure, this is a two in one pen... but that was the problem, while moving the mouse some steps away from the beamer, i didnt see where i point :)
and if i remove the wiimotes ir-filter, even normal sunlight or lamps get detected...
i wanna use the whiteboard in my class, but i cant darken the room, so ir-light is needed i think.

edit: i only tryed with remote-controlls yet, it works great.. will there be better results, if i use a different, stronger ir-led? i mean, its realy no problem to get it to work, but if there is a cheap solution where a laserpointer is integrated and i dont have to built it myself.. maybe it works like i need it :)

U can modify your wiimotes to register the lasers

yea, but doesent the room needs to be dark? like i said, i wanna use it in a classroom where the other puples need to write, so ther has to be light :)
i got the pointer 5 minutes ago... actually great, but its extremly hvy to calibrate, coz it always detects to fast, and i cant click so fast... is there a way, that the calibration waits a second until it goes to the next calibration point?

If you have Linux around, then try the Linux version (homepage in my signature). It is fully customizable and supports multiple languages.

Download Linux Whiteboard from Linux Whiteboard homepage

hey, thats cool, ill gonna try it for my own whiteboard ... BUT, my stupid school doesnt use linux, so if there is a solution to make a break between every calibration point, it would be great...
anyway, even with a "3"-point calibration it works "fine" (cursor reacts very smooth) , i cant wait on how it works with a 4-point calibration ;)

and, sry for my badass english ^^ my dream is, to talk like tommy lee jones in no country for old men :-D

this might or might not work but i was wondering if you could dissasemble a univercial tv remote and use the infared led from that.  i figure it is strong enough to talk to the vcr it should be able to work for the whiteboard.  i am curently waiting for my desktop to be fixed so i can try out my new "remote lazer pen"

I've done this twice.  The first time it worked wonderfully.  I had a strong signal.  The second time it hardly worked at all.  I imagine this has to do with different ratings for different IR LEDs, or something like that.  The nice thing was that it was practically free.  The best thing to do is go to Johnny Lee's website and use the ones he suggests.  They are wonderful.
