Disguise Your Flash Drive As a Mouse

Ever thougt about protecting your data in the most secure way ever? This is a good method to disguise your flash/thumb/pen drive: simply put it inside a mouse.

You'll need:
- an old mouse
- an old flash drive
- small plus screw driver (I used a swiss multi-tool)
- some solder
- soldering iron
- wires (not seen in the pic)

Use the plus screw driver to open the mouse and maybe a knife to open the flash drive.
Be careful not to damage any internal parts.

For this project, I decided to use this mouse only as a flash drive, that's why I cut the white and green wires from the mouse. These wires are used to transmit the data from mouse to PC.
If you want to use both mouse and flash drive on the same device, keep these wires in place.
The red and thin black wires are used to power the circuit board. You'll want to keep them to keep the mouse LED on. To do so, simply remove the insulation cover of each wire and solder it to the flash drive, in the correct position. You can find a good schematic here or in one of the pictures.

Now is time to put all together. You'll notice on picture 1 that there is a soldered wire to R3 (top left). This is feeding the LED, keeping it constantly on. By the way, the other end of this wire is on the thin black on (the terminal in the middle).
The reason why I did this is because the mouse circuit is normally on, but since there is no data coming in or going out (remember we cut the green and white wires), U2 makes the circuit idles.
By jumping the -5V power to R3, althout the circuit still idles, it now cannot avoid keeping the LED off.
In order to fit everything I had to remove some plastic parts from underneath the upper cover of the mouse.

The circuit is now ready for use. No one can tell this is a flash drive, unless they plug it into someone's PC.
Enjoy.
