If you have always wanted a laptop cooler, but not enough to actually buy one, you might be able to build your own. Instructables has a project for a do-it-yourself model that could potentially be made out of things you find around your house.
The project is for a bamboo laptop cooler, but only because it was made using a bamboo cutting board. If you have an old wood cutting board that you’ve been thinking about replacing, you could just use that, instead.
In addition to the 10-inch cutting board, you will need two 12v PC cooling fans, which you can pick up on Amazon for about $5 each if you don’t already have some spares. You will also need an old 12v power adapter, which you might be able to salvage from an old portable radio or other small electronic device.
For the legs of the fan house, you will need two 8″ x 0.8″ x 1″ pieces of wood, which is considered scrap at big chain hardware stores.
As for tools, you will need a power drill, a quarter-inch drill bit, a 2 1/8 doorknob hole bit, a pack of clear plastic feet, some Gorilla Glue or Sumo Glue, and a utility knife.
The easy project requires you to drill 13 small holes and two doorknob-sized holes for the fans. Glue the legs on, mount the fans, place the plastic feet on top, and connect the fans to the power adaptor.
Depending on how many items you already have lying around the house, this DIY laptop cooler should set you back just a few dollars. Plus, you can help the environment by reusing old materials instead of sending them to the landfill.
