First off, I've been a member here before, Asphyxiated was the name.

Ok so I bought a Raptor X case from c3 and recently ditched the crap triangle power/reset switches for Bulgin Vandal switches. I was lazy and ordered the cabling from frozencpu.com along with the switches and shortly after taking them out of the package, the resistor and cable broke apart. After endlessly trying to saulder them back together I am looking for new resistors.

it says the following on the site


Does anyone happen to know what kind of resistor I'd need?

For the 140 ohm you would need the bands to be, brown yellow brown gold. That would be 140 ohm with +/- 5%.

For the 490 ohm you would need the bands to be, yellow white brown gold. That'd be 490 ohm with +/- 5%.

As far as type, just regular resistor.

So to take my 5v hddLED and pwrLED I'd need a 140 ohm with +/- 5%? Sounds easy enough. I went to radioshack shortly after I broke it and they oddly didn't know anything about anything, so I'll go check it out thank you very much!

That's radio shack for ya

NP, +/- 5% would be best as to not kill the LED if it was off. Though, you could get away with higher % but, 5% is the norm for this specific use.

you can get 1% tolerance quite commonly as well... resistors come in various power ratings in watts... so like 1/8 watt, 1/4, 1/2, 1, 3, 7, 10 etc...

where i work the "standard" ones are 0.6W, 1%... watts = volt x amps... so for an LED it's gonna be like 0.1 watt or so, so 1/4 watt and up will do just about any led

Resistor Calculator, should be helpful

So, there was no 140 Ohm resistors at radioshack, what the hell is that store good for?!? I got some 100 Ohm 1/4 watt 5% tolerance and they appear to be working just fine.. I'm not going to burn out my LEDs am I?

My crappy excessive soldering job.

and the switches



and for fun my parents PC, I cut some fire looking lick and stick decals, slapped em on and gloss painted the side of their window.

Anyone?

Ratshack dumbasses...

the nearest 1% resistor values are 130 and 150 ohm... i don't know if 5% resistors come in the same values... but there should be a 150 ohm value i'm sure of it... i'd go for the nearest highest value, so 150 for a calculated requirement of 140... 100 ohms *may* burn the LED out faster than usual because you're allowing more current than the spec...

it depends how the LEDs can cope with higher current than the nominal (usually 30mA) current

solder joints look fine... they're not cold soldered... i would've put heatshrink over the entire thing - resistor, joints, exposed resistor legs, a bit of the yellow insulation each side just to avoid short circuits...

It's all covered up now, I took that picture before I sealed em up. I'll probably stop in there and pick up a set of higher ones when I get the resistors and LEDs for my cd drive window.

Personally being pedantic as I am, I would've used some sort of pre-perferated PCB as a backing to give additional strength to this join, because as part of a wiring loom it may recieve a little added weight & stress


BTW nice little quick-mod to your folk's PC!

haha, thanks. When I get resistors for the cd drive window I'm doing, i'll pick up some resistors over 130 and put those in, wrap em up good. Oddly my parents really enjoy the flames and lights even though their computer is hardly anything to talk about. Do believe it's a celeron 1.8 with 512mb ram and a radeon 9100. Does the emails though and backs up whatever I need so I can't complain since I never use it.
