IR Pens / Alternatives to Vishay Led.
« on: June 26, 2010, 02:02:59 AM »
Hello guys.

I tried to make a whiteboard, its a very interesting proyect.

But i have a problem, i try with a lot of leds, and no one works  fine.

I want to buy a vishay led, but i cant find this kind of leds in my country (mexico), its impossible.

And i search for alternatives, i find this led:

Everlight PT331C.

Its like a clon of vishay 6400.


This led have 940nm of wavelength,  100ma, and 25 of view angle.

In the paper, this led its = to vishay....

This led might work fine??.


PD: Sorry for my bad english.
