Introduction: Desktop Fan
Does your laboratory get hot and humid while you are experimenting? Are you sweating from the effort of soldering a joint together? If you answered yes, then it sounds like you are in need of this desktop fan made from a computer fan. Faced by the heat in my room while working on projects, I tried using a box fan. All that did was blow away my stuff and only deliver a barely noticeable stream of air. After tinkering around at my sweltering desk for an hour or two, I came up with this desktop fan. Even though it may be small, this reused computer fan delivers a concentrated stream of air that cools a work space off like magic. Now wipe those beads of sweat off your forehead permanently and follow this Instructable on making a desktop fan from a few materials.
Before you begin, gather these materials and tools:
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.
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)
