Step 1: The Problem and the Solution
I have seen the things for sale, and for a hundred bucks, they will sell you essentially a closed box with a power strip in it. I can do that for less than $40. Want to watch?
Step 2: The Initial Materials
Step 3: Cutting the Holes for the Cords
On the second hole, I have a 2 inch hole saw and a 2 inch grommet. Guess what, though. The two inch hole saw is internal diameter, not external. The kerf of the blade makes the hole too big. A little silicone glue and it is fine.
If you notice, I cut down the grommet for the 1.5 inch hole, but not the 2 inch. The 2 inch grommet has a spring inside to flip the little plate it contains over. I didn't want to mess that up.
Step 4: Electrical
I also ended up cutting a little deep on the green, white and black interior wires, so I shrink tube those prior to using a crimped butt connector to attach the wires. Never can be too careful when dealing with electricity, and although the cuts were minor, why risk it.
I then shrink tubed the connections again, and then (not pictured) wrapped the three wires in electrical tape to ensure no snags could occur. Now I plug it in and give it a test! Two yellow lights means all is good in the electrical world.
Step 5: The Finished Product.
I did make sure I purchased a power strip with a low clearance plug. That way it would sit flush against the wall.
I have read where some people are concerned with heat build up. After charging a camera and a cell phone simultaneously, there was not sufficient heat to raise the temperature inside more than 10 degrees over the exterior air temp. Not enough for me to worry about, definitely NOT a fire hazard.
I hope you enjoyed this and build your own!
