Step 1: Materials
- 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)
Step 2: Open them up!
Be careful not to damage any internal parts.
Step 3: Cutting and soldering
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.
Step 4: Fit it.
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.
