Step 1: Materials Needed

Picture of Materials Needed

You will need:

USB flash drive
Old Mouse
USB extension cord
Dremel (optional) (not shown)
Assorted Screwdrivers (not shown)

Step 2: Disassemble the Mouse

Disassemble the mouse. Yes, the mouse has a PS/2 connector, this is the main reason that I used it for this project, since it is pretty much obsolete.

Step 3: Disassemble the USB Extension

Disassemble the USB Extension. This may be different for different extensions. Mine was previously used on a Logitech wireless keyboard and mouse, so I just unscrewed it and took it apart. You may have to peel back the plastic on yours to reveal the USB connector.

Step 4: Disassemble the Flash Drive

Disassemble the Flash Drive. This usually consists of simply popping the case off of the electronics inside.

Step 5: Begin Reassembly

Put the scroll wheel back in the mouse (just for more realism). Then connect the USB extension to the flash drive and place it in the mouse wherever it will fit.

Step 7: Finish Assembly

The flash drive should fit under the top of the mouse with no contact. Put it all back together.

I had one question, how does the PC know this is a mouse? Won't the PC identify this as a Flash Drive, rather than a mouse? Or maybe I'm misunderstanding the application...I have an old style mouse and I want to make it into a USB mouse, so I thought of using this instructable...can you please help?

This 'ible is for making a flash drive. This will not function as a mouse when you are done with it. It is made to fool people. You can get an adapter to make a PS/2 mouse into a USB mouse, however.
Make it have both inside the case, as well as a usb hub with wifi and an sd card slot!
dont forget linux on the usb
or find a small usb hub and stick it in the mouse so the mouse can be connected aswell. true stealth usb/mouse. throw a wii adapter in therew aswell and install backtrack 5 on the flash and you have a mouse that can be used for penetration testing.
Just scrape off the little "Logitech" logo with an X-acto knife or sandpaper. Use rubbing alcohol and rub off the "dell" symbol, and say it's a generic mouse you got at the dollar store.
nice one! and lol too...!!!

Not bad... I've been considering trying to cram a usb hub into an optical mouse.  One of the hub ports could be connected to the mouse, one to a large capacity thumb drive and the other wired to a SD card reader. 

I travel a bit and it would be nice to be able to back up my pictures to a drive (integrated into a mouse) and use the drive to host programs to be able to browse the web safely from public computers.  

I should get to work on it...

I did exactly that. It does work, but sometimes you have to unplug and replug it in for the mouse to work. Also, it gets warm during use... Great in the winter. Summer, not so great.
I used this hub and this micro-SD card reader in this mouse. I made it before I joined Instructables. I made a tutorial on a different site.

Hi Dodge, I wanted to change my old PS2 mouse to a USB mouse...what I'm not sure is how does the mouse get recognized by the PC once you attach a USB drive to it?
Dodge premald3 years ago
Oh, wait... I see what you are trying to do. This won't work for you.
What you need is an adapter:

Disregard my comment below.

Hi Dodge, thanks for that pointer. However, what I want to do is actually make my own converter with USB memory stick, and PS2 that I have a USB mouse...what I was wondering was how does the comp recognize this USB mouse?
Dodge premald3 years ago
It's basically just like using a USB hub with a flash drive and a mouse plugged into it. The computer recognizes the hub first, then the drive and mouse. It should be all automatic... Plug-and-play.

I've been telling my friends in the hardware industry that they need to put memory into corded mice so it would be both a mouse, and a flash drive.
I agree that corded, or 'hard plugged' USB devices should all have SOME memory in them.  The obvious use is in wifi devices and printers, where they could contain their own drivers!
As soon as I get money for a chep-o micro USB hub and a mouse, I shall do that and maybe post an instructable about it :) Been thinking about this for a long time and my fingers itch to get tinkering again :) 
I did that a while back, i was rebuilding it to include a dpi multiplier, so i gutted it keeping only the senser. After i built in the new micro controller, i had to use a usb hub to get it to work, because i didn't want to loose a good usb cable i use for my scanner, so i soldered the usb connection to the hub. I also had a 64 GB SATA SSD drive (Pulled from a pocket sized laptop), the size of my thumbnail, and I built it in too. Now my mouse has my games on it.

also a good idea for hiding the drive
