I am not an electrician, so I headed to Home Depot with an idea and some questions. (Home Depot employees have all the answers.) The part-time employee assured me that my idea would work and not start a fire. I rejoiced, built two of them that worked like charms, and decided to share the process.
Here is a step-by-step of how to make easy and safe desktop outlets.
Step 1: Collect your materials.
1 - outlet
1 - face plate
1 - electrical cord with ground wire and plug.
1 - plastic outlet box (I am not sure what these are called. They have plastic tabs that fold out and can be tightened with screws to hold them to the wall, or in this case, the desk.)
You are also going to need a drill, a screwdriver, and a saw of some sort.
