Hi,

The Wiimote has a IR band-pass filter which allows the electromagnetic radiation with the wavelength within the IR range. Therefore, the visible light including the Red light will not be detected by the Wiimote. This is of course can would be different if you have removed or changed the IR band-pass filter.

As an alternative, you can place a IR LED and a visible light LED side-by-side so that the Wiimote can capture the IR dot and the user is able to see the colored LED.

Hi,

From the graphic, it is not clear how the whole system works.

It seems that the IR light is always reflected off the surface regardless of where the user is pointing.

You may want to experiment with IR laser too.

hum...
I didn't know IR laser
I searh around the internet and I found this http://www.dragonlasers.com/catalog/980nm-500mW-Diode-Laser-Lab-Laser-p-16249.html.....to much expensive....

but at same time I discovery that DVD burners have a nice IR laser diode, that rigths?

i'ts is a airgun project

I can shine a box with IR laser, when a bullet perforate the target, IR laser escapes through the hole and wimote capture the point......theoretically it can works

thx for the tips

Hi,

However, IR lasers are quite dangerous as the light emitted is not visible and may blind the user. The IR laser from DVD burners can burn items from a short distance.

For certain, there will be other alternatives for your design. You may want to take awhile to think more first.
