HOWTO build an IR pen



(Rename download file(example:video.flv) and use open it.)

Fast, cheap and easy! There’s no need to solder anything.

You need scissors, tweezers, an infrared LED and a light LED pen.

To use with the WiimoteWhiteboard software by Johnny Chung Lee and the wiimote.

    with one led it would be no use for that.
    but in the video description:

    what the use?

    IR Lights make it heavier BUT IR lights live longer and are a bit brighter.

    ..nonsense… what is the use of that.. its just makes the pen heavier… hate that useless things…

    any idea where i can buy the pen?

    I guess some LEDS are 2,5V and some are 5V, so when you use the top voltage or slightly higher, the LED life span shortens… You might try using 6V, but certainly the LED will last 1/3 of the usual time it uses to… You can ask for a resistor and tell that you want to lower the voltage from 6V to 4,5V, so the desk guy will calculate what resistor you need..

    You did an excellent job with your descriptions of each step. And with each step you made it very easy to watch and follow.

    Just go to Radioshack and grab a resistor

    Need some technical info. I found a S$3 keychain with led which is perfect, just pull out the light led and push in the infrared led and i am done. My question… it is using 2x 3V CR2016 batteries, so I have to use a 6V infrared led for it?
