Changing Mouse LED from red to blue

Read the disclaimer up there ^^^ first

So you have a cool blue illuminated keyboard, and an optical mouse. What colour is the mouse's LED?
I'll bet it's Red.
Wouldn't it be nice if it were blue?

Well, it's easily done. Here's how i changed the LED in my logitech click!

It was red:

So, open it up and take a look inside:

After removing the wheel, and that bracket, the PCB can be lifted out:

Upon closer inspection, it seems that the LED can simply be unclipped from the holder without removing the board. :rolleyes:

Here it is:

Replace it with a blue one, reassemble and Voila!

Reasembly is easy, especally if you take photos along the way. See those two springs on the scrollwheel? I hadn't seen them until they dropped onto my bench. If I hadn't taken that photo I would have been scratching my head for ages figuring out how they went...

MS OPTICAL MICE***************

you can do this to pretty well any optical mouse. i have done this a few times on microsoft mice but there is a gotcha. on ms optical mice there is 2 led's . One for the rear ligting one for motion tracking. you can change the motion tracking easy enough but the one that provides the accent lighting at the back has a red bit of plastic i shines through. this unfortunately acts as a color filter and if you put any other color then red it wont shine through :-( perhaps if someone got inventive with some colored plex and made something about the same shape and size that could make it work out better.

on my computer I have 2 mouses : my Logitech Cordless Click! Plus Optical, which I wouldnt mod cause it works perfecly, plus it's wireless, and some kind of cheap PS2 mouse that has 4 LEDs!! The scrollwheel is transglucent, so the red LEDs make the wheel glows red. Theres another led for motion tracking, and the other one is there only for more lighting...

This is a good idea tho! changing the leds to make them of any other colors.. red/blue/yellow/orange/any possible colors...

Yep, and the tracking LED can be any colour, mine works just as well in blue.

i heard something about a guy named ZapWizzard replaceing his mouse led with a laser pointer's laser led. apparenty he could move the mouse even a few inches off the table surface and it would work. not that its really usefull or anything. just kind of neet to know

lol my mouse barely even has an led its a g5

Hmmm...... there always is the option of putting a multi-colour-changing LED into the mouse, I haven't tried it, but there could be a problem.....

you know you could be on to something with that multicolored led idea. ever knowtice that the intesity of the light is higher after the system thinks the mouse has moved and then it times out and the light gets dimmer. i wonder if there is a way to trap that function and make it run the 2 diffrent LED colors. maybe with like a transistor or something

It is possible, but the circuit I thought up would drain the battery more quickly when in use. Unless you're using a cable, shall I post up a circuit diagram of it?

you most definately are welcome to. i would be very interested to see how it gets hooked up. im thinking to use something like that on a usb cable driven mouse so power shouldent be an issue

Which mouse specifically?

my boyfriend has a multycolor led but I'm getting crazy of it :D

I just whant a purple one but cant find anny :(

If international..... wouldn't have a clue sorry ^-^;

HAHA I feel lil noob now but I can't get me mouse opened:P
I also got a MS optical mouse.. but there now screws in it.. and I tried on all side but cant get it opened.. (and I whant a puple led but I'm not dure they exist :p)

edit:
ok I found a few in Amirika but I live in holland so thats not realy helping..
some one knows some closer? (and I still cant open my mouse I found the opening clicks on de bakc but in frond its still stuck WERE..?¿)

There will be at least one screw underneath a label on the bottom. Turn it over and 'feel' through the labels for a hole, then stick a #0 Phillips screwdriver in there.

Edit:

ive managed to "force" my light to stay on. Around the area of the LED there will be a transistor (a 3 legged black device probably labelled Q1 or similar). This is basicly an electronic switch. When the correct current is applied to the middle leg (the base) it allows current to flow between the two outer legs (Collector and Emitter) efectivly linking them together. The idea is to short out one of the outer legs (probably the collector) with the middle one so the base gets constant current, this will lock the LED on permanently ie: it will not go dim when you lift it up.

See if you can spot the transistor inside your mouse, it will be close to the LED, when you find it use a screwdriver to shot out one of the outer legs with the middle one and watch your LED, when it lights up you know youve got the right leg, solder them together. You could link the two outer legs together but that means fiddling with a wire link around the centre pin as oposed to a solder bridge from the middle to the outside.

Hope this helps some people :)

BTW, im a bit rusty on electronics at the moment so if my terminology is a bit off im sorry :)

ok I got my mouse open (well its broken.. but open.. and can close again but if I drop it it will be opened again..) but ok I'll live with it if its done i can close it forever...
now few probs. purple let, then the mouse isn;t working good annymore (to dark I gess) (my mouse pad is also black so tahts why) + I got 2 leds one in the back 2 but the plex in frond of it is red so maybe if I put in a bleu led it will be beter.. (I'll see for it)

I'll try and make a pic today of my mouse inside may that helps.

Némo

p.s. I did find my screws... there were lil hidden but ok...

because of the type of plastic mice are made from you can use the same glue that you would use on plex and it should seal it for good

its the ms optical mouse. really really really interested in that circut diagram if you have a moment.

Hi I'm new to the forums, I found it through google and it was the first one I saw that might be able to help me with my problem so maybe one of you guys can help me out.

I bought a optical mouse yesterday of my favourite baseball team the Blue Jays, and brought it home everything and it's a very nice looking mouse:

However, the red LED light inside the mouse makes the rest of the mouse look horrible, espcially since it is a BLUE Jays mouse.

I took some pictures of inside the mouse, can you guys tell me if I would need to get a professional to change the LED light or if it's something I could do myself with a bit of instructions? Also, where I could buy a blue LED light.

Thanks in advance!

Erm, you might want to get a professional to take the photos... Can't see that LED very well.
Having said that, if you can remove that small PCB containing the LED, it should be pretty straightforward. Just be sure to get the new one the right way round. Look inside the LED to see the internal construction, there's one large piece and one small one. Get the new one the same way as the old one and you will be fine.

Oh, and welcome to TBCS.

as long as you can get the pcb out its very easy to change the LED, I did it to my friend's mouse today in fact!
Can you solder at all? if not its very easy to learn.
As for getting the LED lsdiodes.com are about the best for small quantities.
Oh and welcome to the forums!
