This will show you how to make a Mr Wiggly mouse jiggler. By default, most windows installations are set to put your computer to sleep after 10 or 15 minutes of inactivity. This can usually be disabled easily in the control panel, but there are some times when this simply isn't an option. For instance, if your company has policies in place to enable this feature. For me, i am a PC tech, i had a computer come into the shop that had apparently started upgrading from windows 8.1 to windows 10, and then went to sleep in the middle. When i powered it on, it continued the installation, but kept going to sleep if i didn't wiggle the mouse every few minutes. This device can be used to prevent a computer from going to sleep.

Step 1: Items Needed:

USB optical mouse

small pc fan

wire cutters/strippers

screw driver

soldering iron

drill or something else to make a hole (I used the awl on my swiss army knife)

Step 2: Attach Fan

Line up your fan so that the center label on the fan is positioned directly under the optical sensor of the mouse. Using a few screws, attach it to the mouse. I used small washers to add just a little space so that there was no friction. Use short screws so that you don't screw them into the circuit board of the mouse.

Drill a small hole in the bottom of the mouse for the wires to go through. I used the awl on my swiss army knife to do this.

Step 3: Connect Power and Ground Wires

Cut off the plug from the fan and strip the red and black wires, tin the tips with solder

solder the red and black wires from the fan to the red and black wires on the usb plug that connects to the mouse circuit board.

Step 4: Reassemble

Put your mouse back together. Once completed, plug it into your PC. the fan should start spinning and your mouse cursor should start wiggling all over the place. Now if you need to walk away from your pc, you can plug this in and it will prevent it from sleeping.
