I was able to play around the Wu brand remote.  As it turned out, IR tracking is really poor.  I've been trying on different positions.  The reason why I am saying that this remote would be useless for our project is that I have mounted my original remote in a position where I could have perfect tracking.  After that, I replaced the original remote with the Wu brand in the same location/position as the original one.  I was only able calibrate a single corner of my screen.

I guess, I will just use the accelerometer in this remote for other purposes.

My advise to the others, please buy the original remote.  :)

I will post my findings too when I get my hands on it.

Good point Ben!

I have read the reviews from the site of people who have purchased the Wu brand controllers, and they were pleased with the results.  If the cheap controller that they bought worked seamlessly with their original Wii consoles, I would assume that it would work well with our project.  I am risking continuing with this purchase to see if I get good tracking of the IR blobs, if so, then I would have cheaper alternative.  Current original wii controllers that are available locally(Phils.) range from 55-60 USD.   :)

Darren,

Is this the one that you got ?

My order is still being processed.  If you can confirm that the one that you received is the same one linked above, I might request for the order to be cancelled.

Thanks,

I believe that your projection screen is the culprit.  If you are bound to the type of screen for so long, you'll have to create a special pen for it.  A backwards facing pen, or a pen with LED in the front, but tilted at an angle so that your wiimote sees it directly would do the trick. Much cheaper than buying a new projection screen.  :)

IR Pens / Re: Homemade telescopic IR wand

woah .. this is nice.  I didn't think about retractable wires before.  Now that you mentioned it, I think I will be able to use this on my wand.  I was able to get some good retractable pointers from DealExtereme today. Here''s the link:

Thank you for sharing a great idea Fastolfe !  :)

I attempted to create one last weekend using a TV antennae as a telescopic tube.  It gets very narrow near the end though, so I ended up  "parking" the project until I can find a ready made telescopic stick that is not too narrow at the end where I can run a single wire (+) and use the tube as the gound (-).  I am still looking for a professional looking telescopic stick that is being used the classrooms.  Can you please point me to the url for the expandable phone charger that you used ?   :)

Thanks!

and oh, I failed to mention.  If your pen is too short, you will not suffer from the problem that I mentioned, and tracking would get more accurate.  Depending on how you would want to write onto your board, I guess your setup is fine.  Some people prefer the feel of a longer pen, I know I do.  :)

IR Pens / Re: Vishay TSAL6200 - Can it be used
« on: February 20, 2009, 06:24:02 PM »
Dear experts,

I was not able to find the TSAL6400 in Germany. Also no OSRAM (even though they are german :D ). So I ended up with a shop offering the TSAL6200. Can it be used to make a pen? I know the angle is smaller than the 6400... But are there experiences?

I agree with Ben.  You will have poor tracking on the 6200s.  I have ordered online for 6400s from mouser.com.  Shipping to the Philippines is a bit pricey ( 40USD ), but I ordered a bunch to make it available locally.  Buying a lot compensates for the pricey shipment because you will get it cheaper that way.  What I suggest is you buy in the 100s and introduce the project to your community.  You can supply hobbyists in your area so that you can recoup your investment, at the same time, make the part readily available to them without them having to go through the hassle of ordering online.  Mouser uses FedEx, so you can track where you package is at any time.

I have tried it by just inverting the pen that I created, but you will have to be very careful to keep both ends parallel to each other with respect to the wii remote to make sure that the end that touches your surface is totally aligned to the other end where the IR LED is.  You will definitely benefit from the IR remote always seeing your IR source, but it would be a bit of a challenge if you would want to use your IR pen as you would do a standard marker/ballpen.  Ex. if I am going to write a down stroke onto the surface, the effect on the other tip would be an upward stroke as seen by the wii remote, except of course you keep the discipline of aligning both ends with respect to the remote mentioned earlier.

Wiimote Interactive Whiteboard / Re: Succesful setup , write, left click
« on: February 14, 2009, 10:31:25 AM »
This can be implemented with an IR pen that can fit the smallest RF wireless mouse ( http://www.asus.com/products.aspx?l1=27&l2=145&l3=658&l4=0&model=2141&modelmenu=1 ).  I am yet to see how much this is though.

IR Pens / Re: I need help
« on: December 03, 2008, 02:06:09 AM »
Questions:
- are you using a projector to project your laptop screen to the whiteboard ?
- how far is your wiimote from your screen, and at what angle in front of it ?  Have you tried different positions/distances ?
- what type of IR LED are you using in your IR pen ?
- Have you tried facing your IR pen to your wii remote while in calibration mode, and then turn on your ir pen ? What happens ?


This happened to me, and it turned out that either my IR pen is not powerful enough, or my wiimote is not positioned properly to see the IR light from the pen.
