Before you begin, gather these materials and tools:
- crimping tool (available at your local hardware store)
- two wire splices
- 12 volt adapter (see my instructable on how to convert a cell phone charger into a power supply)
- 12 volt computer fan (these can be found in computers and large electronics)
1.) First, if you are using a normal adapter, cut off the plug at the end and strip the two wires.
2.) Next, insert a wire from the adapter and another wire from the fan into a wire splice, noting polarity (red wires positive, black wires negative). Crimp the wire splice with the crimping tool tightly. Give a gentle tug on the wires to make sure they won't come apart.
3.) Repeat step 2 on the other two wires. Your adapter should now be connected to the fan. Check once more to ensure the right polarity, and then plug the adapter into the wall.
The fan should immediately start spinning! Sit back and admire your little creation as it cools you and your work space. You can mount your fan on a base by attaching zip-ties through the screw holes in the fan and some pre-drilled holes in a small block of wood. Set your fan in the corner of your desk and enjoy the cool breeze.
