Blue-ray laser mouse?

Just got a new logitech 450 and it uses a 848nm laser at 1.4mW and was wondering if anybody knows if you can take out that diode and replace it with a phr-803? would the receiving end of the mouse pick up the light and translate it to movement? I just think that glowing violet light coming out of the bottom would look pretty sweet and since there is some kind of voltage regulator running the IR from 2 Li batts in theory....

why not just use some uv leds..?

The original wavelength is in the IR... and the 803T is near UV...
Normally photo detectors and CCD sensors are sensitive to IR but not
as much at UV frequencies... I see a problem of beam sensing at the
same power levels... :-?

i thought about just installing a led inside the mouse and that would create almost the effect of putting neon under your car but not only is that easy but i don't know if that would mess with the sensor or the laser's input voltage. and the other comment leads me to believe that i would need to put a red diode in there for guarantee that the sensor would pick up movement. another thing that i wonder about is when i took it apart there are not one but 2 LD's in this mouse i guess one is 1A and one is 1M. if anybody has any ideas post em.

Yeah, I had trouble using my logitechs after replacing the red with a blue LED... That's a smaller difference than you'd get from near IR to near UV. I wouldn't mess with the laser doing the actual work. cosmetic if you can, sure, but not the IR diode itself...

besides, 1.4mW is not gonna be one helluve glow :

That's a smaller difference than you'd get from near IR to near UV.

You mean from near IR to "nearly" UV

It's probably doesn't actually use a laser - I took apart a broken laser mouse, to be met by a cheap but bright LED.... Though, a proper, nice mouse from Logitech might be different - I'm guessing, since my Logitech one is at 848nm too, and claims to actually use a real laser...

You probably won't be able to use a PHR-803T because of the difference in wavelengths. The mouse's CCD will be fine-tuned to run at its diode's wavelength, and other frequencies may even be filtered out to increase sensitivity. Also, I may be wrong, but even if the CCD could detect it, the difference in wavelength would make the speckle pattern very different compared to the other one.

You could probably set up a miniature second laser using an independent regulator shining onto the desk, to create your glowing effect, though. Shouldn't be too hard, if you're prepared to cut it open and operate on it, but you'd need to run at low power to keep it cool. Even then you run the risk of smoking your desk (MDF is really easy to smoke) and destroying the mouse. Smoke on micro lenses near sensitive sensors is to be avoided...

Sounds like a great idea, the mouse is real easy to take apart, and it's a laser (confirmed with ax. mod. and night vision) and i just got the logitech VX Nano so i got a backup if i screw it up...thanks for the input

Everyone see's a glowing red light and calls it a 'laser mouse'.

A [highlight]laser mouse[/highlight] is just that, a mouse which uses a laser for tracking. An [highlight]optical[/highlight] mouse uses a bright red LED for tracking. Optical = LED, laser = laser, but everyone seems to just call either one a laser mouse.

If there is a laser in laser mice.... why do the specs of the laser mouse
not show the wavelength and output power of the lasers being used... :-? :-? :-?

[Edit] This has got to be a first.... I'm actually ASKING a question.... ;D

True Jerry. What about my lpm naow? :

My bro has a bluray mouse. It a 1mW using RF for cordless. Runs on 3AA

Business by PM stays in PM... :

Do you have a model number of the "bluray mouse"...
or a link to the spec sheet...:-? :-?

He got it last summer, i remember it was a Logitech prototype.
It look like cheap Razer gamer mouse.

With all respect... Are you sure he wasn't jerking your chain?

my mouse has a laser in it - not sure why the camera showed it as blue though, you can't see it by eye

Then it would be IR if you can't see it but the camera can.
