Hi,

I have been very interested with the WiiMote projects and decided to start them myself.

However I am not too great with electronics and was wondering whether there were any alternatives to gain an appropriate IR source?

After searching around on the internet, I havn't found any thing specific other than the following items, which I have no idea whether they will work or not:

InfraRed Heat Lamps (150w)?

An InfraRed Globe Bulb (110v/375w)?

InfraRed Ruby ES Bulb (250w)?

A CCTV Camera InfraRed Illuminator (featuring 24 IR LED's, 12v PS)?

If any body could help I would greatly appreciate it!


Many thanks,
Chris

I built an IRarray myself, a kit from Kemo...

It works just like the CCTV Camera InfraRed Illuminator...

I also used some reflective tape on my fingers to get better tracking

Thank you for your response.

As I am trying to recreate a large array, I am now looking at IR Illuminators, and increasing the project budget. It may not be as cheap as building an array (..even that depends on how many LED's I try) but certainly much less hassle and time.

I also have some reflective tape, designed for use on vehicles, so I hope that will have the desired effect!

Update:

After deciding to use an IR Illuminator I thought I would share the information:


I bought this, the IR Illuminator IR100 850nm from http://www.rfconcepts.co.uk/ir_lights.htm and is worth every penny. Sure it is expensive, but it is extremely powerful (more powerful than 940nm LED's) and with a lot of LEDs. I find the range for finger tracking to be very good.

The downside is the price, but on the up side it's ready assembled and works straight from the box... apart from attaching a 12v PSU. :)

A very good alternative to building an array yourself.

It is I can assure you! 8)

I saw another which claimed to be more powerful but, opted for this one due to the extra wide arrangement, which increases the overall  beam width. :)

Fire.

Light a bunch of candles. They give of IR light. It's great for testing, but not very concentrated.

Chiss,

Do you have any more update on the feedback on this IR Array?

How did you placed the Array/Wiimote together?
How well did it work with your reflection? What reflector did you use? How far away?

Thanks!
