A while ago I got an old desk from my grandpa. It was really filthy so I decided to sandpaper it, but when I was done I wasn't quit happy. I wanted to pimp or modernize it so I choose to build-in some sockets for my laptop or iPod, but when I didn't need them it had to be possible to hide them.
When I looked up a ready made system I saw it cost 370 euros !! That's when I decided to make it my self !
Here my instructables ! Have fun !
Step 1: Opening
First you have to decided where the sockets must come.
Then you have to make an opening (a square of 10cm). I did this with a small drill and a jig saw. You could use a fretsaw or a dremel.
It's important to damage the square you saw out as less as possible, because it is reused as the cover. But you could use an other cover to.
Step 2: Create base
It's important to have a firm base, but this is dependent of the desk you have. The back of my desk wasn't strong and thick enough to secure the system, so I used two hooks.
Step 3: Attach the sliders
The slide system is just with some draw sliders. Use the ones with bearings. Before you attach them, you have to push the outer flanges a little bit inwards (with a vice). This creates more friction and prevents the sockets to slide down because of the weight.
Step 4: Attach the sockets
You can attach the sockets to the sliders with glue or by screws. IMPORTANT when you use screws, make sure the screws do not touch or damage the electric cabling inside the box !!
You also have to attach a hook on top of the box. This hook attaches the cover to the box and because the hook is made out of metal, it's also used for the magnetic lock system.
Step 5: The lock system
For the lock system I used a magnetic pressure catch. Just mount it so the magnetic part connects to the metallic hook.
