Adding Weight to Your Microsoft Wheel Mouse Optical 1.1a


Introduction: Adding Weight to Your Microsoft Wheel Mouse Optical 1.1a

About: I like to repair hardware and software issues in computers, I like it mostly because a lot of it is like a puzzle to me and is a relief when I solve it.

Well, this instructable is a tribute to people who don't like those cheap feeling lightweight mice. I did this when recently a wireless mouse I was borrowing from a friend (A nice logitech media center one at that), he bought a new computer and wanted it back. Hesitant, I did give it back and in exchange he gave me a microsoft wheel mouse optical 1.1a mouse. Now, I like it tho because it's hooked up to my mac laptop and there's a certain irony. Anyways.

Being used to the heavy weight of the mouse, being there was batteries, I was annoyed at the weight of the mouse being so light. It was horrible. I decided that I needed to put weights inside of it, I happened to have a copper ingot that bonds pretty well with super glue.

What you will need:

- Microsoft wheel mouse optical mouse, pretty sure revision doesn't matter
- Metal weight of some sort (having one solid chunk is handy)
- Possibly a dremel, depends on what you find to use as a weight
- Flat Head Screwdriver
- Superglue of some kind
- Patience and a steady hand

Step 1: Take Apart Mouse

I apologize, I can't make those yellow squares on the picture as I'm on a mac and it wants to just drag the picture.

As you can see in the picture, 4 feet, I of course have taken them all off. The two bottom feet cover two screws while the top two are clips that you will need to pop with a flathead screwdriver. Damn you microsoft....., anyways, procede to take them out, I already have as you see below. The two clips will be very tricky, it's a combination of pushing on the very hard and pulling on the bottom, which should be free to move if you've already removed the screws. After some tricky work, you should now have the cover off. And as you can see from my crappy webcam pictures, there is little space to work with, very very little.

Step 2: Time to Think!

My copper ingot* was about 3/4 inches long, too big to fit anywhere and have it fit right. So it turns out, I have to cut it in half with my dremel and a cutoff wheel. It was tough work, got some burns in the process, covered the floor in metal filings and such, messy messy. As you can see, the mouse cover inside. I have super glued the two halves inside. However, the right half I had to cut it somewhat diagonaly as the wire going to the interface board was in the way, remember guys, when putting the cover on, make sure nothing is interfering or putting pressure on the usb cable or you might damage it if you force the cover on. Also too, make sure you glue whatever you put in as a weight so if you slam it, drop it, ect, the weight will not come loose and rattle around.

Step 3: *

Well I hope you had luck at adding weight to your microsoft mouse, it certainly helped me (I play a lot of halo on my mac). Enjoy, and if you guys have any probs at all, email or pm me and I will be glad to help.


Ingot - To those who don't know what and ingot is, it is a solid peice/block of metal, whether it be copper or aluminum, it's called and ingot.

    i hate those! i always press them on accident

    Recently my wireless mouse sad now.

    Does anyone have one of those black Dell mice? The mouse wheel in mine has really wide spaces in between "clicks", and is constantly twitching the wheel and scrollbar up and down when I use it. VERY annoying.

    flip it over and blow past the hole with the led for tracking, usually it's no more than a hair or fluff in there... dell mice are sensitive as hell for some reason and that really upsets them, as a result i use a £3 game mouse that is always found in the bargain bucket...

    I've taken it apart many times and the problem is not dust it's a little piece of metal. It's pointed so it sticks in the gear teeth. This is what makes it "click".

    Ah got you now, I thought you meant the pointer was twitching, you could take the click out and make it smooth scroll but we have a mouse that went like that and age does kill them

    yah, makes me very angry...i almost want a mighty mouse...(and a mac!)

    i have the same mouse as him....its great i had the same problem too! i have two microsoft mice beside me one wireless i got recently and a same one he had, just black.....and i switch off between them...... gets you more used to the light weight....if you dont like it switch, if you dont mind switch back....

    Is that Hobbes or Tony the Tiger?

    Ur an idiot you posted a reply on another instructable saying " Jan 19, 2007. 3:24 AMMr.Devioussays: Although you put honest time into this, can you not waste web space with something that hasn't been don't a hundred times?" and then ...... this "Thanks LasVagas. I figure this has been done before, I didn't find any actual posts, but this is my first instructable and I'll have more better ones coming your way shortly. Just figured this would be nice to see inbetween the chip dip and usb ipod charger instructables. Cheers" ur a tard

    So posting on another instructable aka mine, doesn't make you a retard then? Becuase you're doing something you're claiming I just did.

    Thanks LasVagas. I figure this has been done before, I didn't find any actual posts, but this is my first instructable and I'll have more better ones coming your way shortly. Just figured this would be nice to see inbetween the chip dip and usb ipod charger instructables. Cheers

    good, but its been done before.. i think. it looks pretty light and small. mabee you could strip it down with a dremel, and glue a "finger glove" on top so it would be super small... just because

    Nice idea! I especially like the Tiger Mod at the end! lol
