Hi,

I make some pages about Wiimote Whiteboard.
http://clinik.net/wiimote/

One of them is about my IR Pen.
http://clinik.net/wiimote/wiimote_info_my_pen_1.php

I hope it help people like me (not so expert in this hi-tech things :) ) to understand the Wiimote Whiteboard functioning and, therefore, to try it!
Cheers
Francisco

IR pen looks good I am going to be working with my MacBook Pro and seeing if I can get the Wiimote Whiteboard working on that.

Site looks great as well

Dice,

I work with a Macbook Pro (10.5) with no problems!
As you may know, just place the wiimote in the right location and find a good IR pen.

And for the IR pen, you must try the momentary switch with lever!!!
I first see it in the "Faber-Caster" IR pen from UndCon! I use other model, with a tiny wheel. It's very smooth. Better than most mouse clicks:)

Im glad I inspired you with the switch - I was looking at that model (with wheel) as well but opted for the one without... do you like the feel of the roller or do you think it is better without ?

Hopefully I get my soldering iron back this week from my friend so I can finish off my tutorial...

You may see here:

as long as you can make the hole (img 3), the feel of the roller (white plastic, in my case) is quite good!!!

And which Led you use?

Hi UndCon,

How you can get the IR-led from KEMO because I saw on their website they only sell it to company or the industry only, not for private person. Since you live in Sweden, do you know which places are selling cheap and low delivery cost in Europe?. I can't get the cheap price in Finland :( they cost me a lot even shipping 15 for just delivery inside Finland :o.

I bought mine at www.kjell.com #89281

http://www.kjell.com/content/templates/shop_main_details.aspx?item=89281&path=239000000,288500000,289000000

I also bought my IRarray there (Kemo B223) -#87223

http://www.kjell.com/content/templates/shop_main_details.aspx?item=87223&path=239000000,242500000,244000000


Im not sure about shipping to Finland from Kjell.com...

Also try Conrad.de and choose international

(or conrad.se if you can cope with swedish)

Thank for your info Undcond. I tried to order in Kjell websilte, it's very weird that they cost me with a terrible shipping cost :-) about250 SEK for only 10 pack of LED (29SEK) :). Well I had ordered in DealExtreme : 20 leds, 5mm  IR-led,
http://www.dealextreme.com/details.dx/sku.2399

I have no idea about its spec and I think it 's not good led but for only $2.93 (free shipping) so it's acceptable. I wonder if it is a weak LED, can we make a IR-pen with 2 leds in a series in order to make it strong enough?

If you want me to I can buy at Kjell as they have a store in my town.

I can send you a letter with some bubblewrap at the cost of about 10SEK

So you have them for about 40 SEK

Send me a PM if you want to talk about it...

Try: http://uk.farnell.com/

The Vishay TSAL6400 came from UK posted to Australia for free (min $10 order). I assume should be able to post to Finland for similar cost???

UndCon: Given it is acutely obvious the best results are in the Vishay TSAL6400 and there are numerous post on the same topic "where can I buy them from?" is it worth compiling a list of suppliers perhaps through a wiki so can be modified and updated by users???

It can be a good idea - but if people search or read several posts before they start off it is not necessary


EDIT : spells like a cat (as usual)

UndCon,

In my 1st IR pen I used the
Vishay TSUS 5400 (with some diffrences from the TSAL 6400)
 
Fortunately, my local store found the
Vishay TSAL 5300 (almost like the TSAL 6400)

TSAL 6400
Angle of half intensity 25
Peak wavelength 940 nm
Forward current 100 mA
Forward voltage 1.35v - 1.6v

TSAL 5300
Angle of half intensity 22 (this is different - I conjecture its better)
Peak wavelength 940 nm (in the led bag said 950nm)
Forward current 100 mA (equal)
Forward voltage 1.35v - 1.6v (equal)

I will make my 2nd IR pen with this 5300 led plus a 12v battery with a 1,2 Kohms.

Can we say that TSAL 5300 is better than TSAL 6400?
Have we a 'new' winning IR led?
:D

Can you (or someone) help me with this technical features?

Thanks
Francisco
