Title: Poker leds.
Post by: fossala on Sat, 29 October 2011, 06:24:20

Does anyone here know the specs of the leds in the poker? I am looking at replacing them with red ones.

Blue LEDs typically need more juice (3.2-3.6v), so you have to add resistors (http://led.linear1.org/1led.wiz)...

Thanks, what would happen if I didn't. Would it just be bright or would it blow the led? From something I read on hard form I am lead to believe the blues are only running at half brightness.

For a higher forward voltage you actually need a lower resistor value to get the same amount of current flowing.

edit: reread, and found that's exactly what you were saying :)

It will be brighter and possibly die earlier. If you have a multimeter you can measure the voltage and current and find the appropriate LEDs on ebay (=

I have a multimeter but I don't know how to use it.

It is back in one piece now. I will take it apart again when I receive the clear stems from BINIRIS.
