Resistor Question.
« on: August 23, 2008, 12:36:56 PM »
if i use these leds to swap both the power and charge led - http://cgi.ebay.co.uk/10-160mcd-ULTRA-BRIGHT-BLUE-0603-SMD-LEDs-SMT-LED_W0QQitemZ260277768179QQcmdZViewItem?_trksid=p3286.m20.l1116

and then use the 3.6v point on the powerboard and the hold switch point as ground, to try and power 8 of those same leds, what resistor is needed? 10ohm causes the leds to be too dim, wondering maybe a 1k but i dont wanna risk burning an led out.

thanks.

no resistor.... these can take up to 3.8v (according to the seller) so i dont think you need one.....

thanks chase for this sig =)

wait a sec isn't 1k 1000 ohms? you leds won't turn on at all with that.

Probably just use no resistor as Bhawen Said

lol crap yea forgot, i left the 1k and they seem to work fine. i think i remember reading from a post by fufa i think that the powerboard gives off more then 3.6v i cant remember.
