Hey /diy/, I would like to disable or (preferably) remove the blue LED from this USB hub. I was considering simply unsoldering it. I have a cheap 40w soldering iron, and have gotten pretty good at splicing and repairing copper wires over my lifetime, however that's the only soldering I've ever done.

There is a complication.

>>	Anonymous Tue Feb 28 21:23:53 2012 No.163870 Just put some paint on it. LEDs produce next to no heat, and consumer very little energy.

The actual hub chip is directly opposite the LED on the PCB. This scares the shit out of me - I'm afraid I'll be heating the LED leads and the chip is gonna fall off or something.

Is that a legit concern, is there a particular technique I need to use to protect the rest of the board?

Or do I need to give up entirely, crush it with a pair of pliers, and cut the leads short?

That's something I obviously considered, blocking it with tape, paint, etc.

But I'd prefer to cleanly remove it entirely, if possible. Call it personal preference.

>>	Anonymous Tue Feb 28 21:31:49 2012 No.163881 >>163874 dude seriously , just cover it with some blue-tack or something

>>	None !dMd365bEEU Tue Feb 28 21:34:13 2012 No.163884 >>163879 I will do that if I have to.

>>	Anonymous Tue Feb 28 21:35:22 2012 No.163885 >>163869 just cut the leads dipshit.

Hey /diy/, I would like to remove the ugly stubs left behind where I clipped the leads to a blue LED on this USB hub. Can I unsolder them without damaging the attachments for the chip on the other side?

>>	Anonymous Tue Feb 28 21:56:46 2012 No.163917 why dont you like LEDs?

It sits on my desk near my monitor by necessity - the length of my mouse cord requires it. It's also convenient for me to have a USB hub in that location anyway, for plugging in thumb drives and whatnot.

It's blue, and shines in my peripheral vision whenever I'm playing the vidya, jacking off to porn, or watching pirated feature films. If the hub's case ends up with the LED pointing in my general direction, it is painfully bright.

I hate blue LEDs

>>	Anonymous Tue Feb 28 22:04:41 2012 No.163924 Itt: anal faggot. Seriously it's not that hard to de solder and led

Of course I'm an anal faggot. If I wasn't I would have stuck a piece of electrical tape over it screwed the case back on.

I'm not worried about desoldering the LED. I'm worried about accidentally desoldering components on the opposite side of the PCB in the process.

>>	Henry Bankshaft Wed Feb 29 01:54:53 2012 No.164111 Remove the stubs with a small file or rotary tool

>>	Anonymous Wed Feb 29 02:02:42 2012 No.164119 >>163925 Pointless worry. You'll ruin the PCB much faster than you can desolder the chip on the opposite side. And yes, it's easy to see when you've ruined the PCB.

>>	None !dMd365bEEU Wed Feb 29 02:43:38 2012 No.164149 >>164119 Thank you for the 1st serious reply to the question I originally asked. I've never soldered on PCB before and am not familiar with how it conducts heat. I'll just get these stubs off, then.

>>	Anonymous Wed Feb 29 03:35:45 2012 No.164184 >>164149 After that I wonder if you should be adding a resistor in place of that LED...you never know with these PCB's

Anonymous Wed Feb 29 03:45:49 2012 No.164187

>>164149
I suggest using a small tweezer tool to hold onto the stubs, and apply soldering iron to stub, while holding the entire thing slightly above the workbench surface. Let gravity do rest of the work, those things don't break easily so don't mind dropping it a little. Use solder sucker for any remaining solder, if you have one.

>>	Anonymous Wed Feb 29 03:47:05 2012 No.164192 >>164184 Knowing how LEDs are often used (parallel to voltage source), it probably won't do anything to the rest of the circuit.
