Title: Where to get stock powerboard led resitors?
Post by: juust0_ on February 15, 2009, 06:20:43 PM
So, i accidentaly moved the wire that were soldered to other end of the resitor and it broke. Where do i get new resistors and how many ohms are those stock ones?

   What was your project? Were you doing the led swap? If so, and accidentally you broke it off, then you really don't need the stock resistors. All you need to do is bridge the 2 solder points were the factory leds were and solder does 2 solder points. This will make the newly install leds light up much brighter.

I will check the resistance in a when I head down to my workshop (aka shed) later, they are 0402 resistors. If your soldering skills are sub standard then these may be a pain in the ass to replace. 0402 componets can be found in many places around the web.

I took one resitor from my other powerboard and soldered it. Now my powerboard works fine. Does the leds handle the voltage, if i just bridge those resitors? I have blue power and red charge leds.

no way on the red.

Il test if the blue works and how long without resitor. The blue should work on 3.6v and the board gives 3.6v? Then it isnt big deal.

no show me the data sheet for your resistors, I recomend you use a resistor.

What else could happen that the led could fry? My psp has been running now for 2 hours to test if the led works and how long. I used multimeter and it shows that there are 3.1 volts going through blue led. The led is too bright, im getting headache if i play with it :D

3.1v won't fry your led, but it will shorten the life of your led a bit. But yeah that happens when you run leds over their forward voltage.

What he said

I run my blue LEDs at about 2.8, making it slightly under almost doesnt effect brightness and doubles the lifetime lol

I dont care much if the lifetime is still something like 500 hours or so. What kinda resitor should i use to run the led like 2.8v?

Am i right that the board gives 3.6v and not 5.5v?

EDIT: I only have 10ohm resitors, so i added 1 but seems it doesnt have nearly any effect.
