Make a Raspberry Pi Case That Plugs Right Into the Wall
If you tend to use the Raspberry Pi as a headless computer, you don’t have to deal with a lot of cables. If you want to get rid of another one, Instructables user grega994 will show you how to assemble a case with an integrated power plug so you can plug your Pi directly into an AC outlet.
Grega994 basically plugs a 5V charger into the Pi and then builds it into the case. From there, he can simply plug the Pi straight into a wall outlet. If you don’t need a cable and tend to use the Pi like a headless machine, this is a great way to get rid of the clutter.
