Instructables
I've been browsing this fantasic site, and came across Johnny Lee's Wiimote project.

Here's a clip of what he has found:



So I thought I would try building my own Pen and find the items required in Australia.
I have completed my Pen and have also found an easily accessible Bluetooth device.

We use this now at the School I work at, and it is a handy device and inexpensive to build.

We can use it on any whiteboard, wall, Laptop Screen, or external monitor you can think of.

Here's the finished product:

I'm sorry if this sounds like a stupid question, but I picked up two LED's from radioshack. The only thing is that they are red, rather than blue, which is what I see in the tutorials. I'm not sure if this would make a difference whether it is infrared or not.

The LED's need to be Infrared LEDs. That means, to the human eye, you cannot see any light coming from the LED (aside: a good way to test if the pen is working is to use a photo camera on point the LED at the camera and press the button. You should now be able to see a light source through the viewfinder...the lens in the camera picks it up and translates it as a white light source). So A RED or a BLUE LED will not work. It must be Infrared. Ask the guys at Radio Shack. Also, one thing I noticed when looking at the Radio Shack LEDs was that the voltage was higher, meaning you may need more than one battery (I think it was 2.3 V which would be two 1.25V batteries?).
Ok. Thanks for the info. So this would not work?

Correct. It needs to be Infrared not Red. It's the same sort of LED that is in your TV remote control. You can't see the light, unless you aim it at a camera. and look through the display... I have had a look at Radioshacks web site. Cat # 276-143.

Looks like someone else has used it for this project before (look in comments): PERFECT for wii projects.

Cool instructable. Hey, I lnoticed that the Dick Smith PowerHouse's in Australia (VIC at least) Don't sell the small LED's and resistery type things anymore. Do you know where I can get these without having to go all the way to the nearest ordinary DS store ( a long way away)? Thanks. Anyways, good instrctble. +1

I suspect that they could order it in from their head office however? Give them a ring and ask if you can order the products??
Thanks for the suggestion. I just found out that there is a Jaycar Electronics store close so I'll go there. Thanks Anyway.

Just make sure the voltage of the LED Suits the battery you are going to use, else you may need a resistor.
