I wanted to add a LED on my Logitech mouse
where the LED would blink when i move the mouse.

I wanted to do this WITHOUT using a PIC chip or a 555 timer.
So all you need is one led diode.


Step 1: Parts.


Parts needed:

- Mouse (i used a logitech mouse model: M-S48a)
-One LED
-Voltmeter
-Soldering Iron


Step 2: Disassemble the Mouse

First Dissasemble the mouse
There's a screw underneath the mouse.
Once you open the mouse, use the volt meter to measure the voltage between pin-5 and pin-13 on the A/D converter .
By moving one of the wheels of the mouse you will notice a voltage difference accross pins 5 and 13.
This is where you'll connect the diode.
If you're using a different mouse (other than Logitech) just try measuring the voltage between each pin while you're moving the wheel at the same time. Once you find a voltage difference between two pins, solder the LED there.
Make sure you use the right polarity of the diode.

Step 3: Solder the LED

Solder the LED on pins 5 and 13 (watch the polarity of the led) and drill a hole on the side of the mouse cover for the led to fit

Step 4: Close the Cover and Enjoy

Sit back and enjoy....

<p>I can't see your video, it says its private.</p>
&nbsp;THIS IS AMAZING<br /> NOW I AM GOING TO DO THIS/DID ON A BALL MOUSE/ SAME EXACT MODEL<br /> BUT I AM CURIOUS TO KNOW IF IT&quot;LL WORK ON A OPTICAL MOUSE<br /> I&quot;M 99% SURE IT WOULDN&quot;T THOUUGH BECAUSE IT DON&quot;T WORK THE SAME
thats cool!
Cool, might try this in the up coming vacation :-)
Although you got it to light up, I don't think that it will blink when you move the mouse... Other than that great job! Oh, and that video gives me headaches... tooo low of a frame rate!
"Although you got it to light up, I don't think that it will blink when you move the mouse..." Yeah it does...
Okie, sorry about that.
Really though, if you move it only along the vertical axis, it won't light. The way you have it set up is only for the horizontal axis.
actually if u watch the video it does light up when moved along the vertical axis alone
nicely done, great pix. I have several of that same meter, sweet.
lol mine is better the whole back of it blinks when I move it. It did this when I bought it.
