Step 1: Parts & Tools
Here are the parts and tools you need to build this. You will also need something to hold the lamp socket in place while the concrete is drying, like for example BBQ sticks or thread.
- Lamp socket.
- ON/OFF switch (to connect to the cable).
- AC plug with a long cable.
- Bucket to mix the concrete in.
- A big spoon or something to mix with.
- A form of what shape and size you want yours to be.
- screwdriver for connecting the switch and socket.
Step 2: The Form
I made my form so that the lamp is L: 10cm B: 10cm H: 7cm. Its smart to make the walls higher than what you want it to be and make a straight line at the point where the concrete is going to stop.
Poke a hole in one of the walls for the cable to go through.
NOTE: in my form I used a material with some kind of paper on the surface, that will make the finished concrete rough on the surface and I had to use sandpaper to smoothen it out.
If you want a smooth finish than your form needs to be smooth to and not made of paper.
Step 3: Lamp Socket
In the picture you can see my lamp socket, I took it out from an old and broken lamp that I had.
I pushed the cable through the tiny hole and placed the lamp socket where I wanted it to be and adjusted the cable length that was inside.
Step 4: The Concrete and Filling the Form
Take a big bucket and put some concrete in it (depending on how big your form is).
Add some water (not to much!) while you mix it together, keep adding water until the concrete is like porridge.
When you get the concrete right mixed then its time to fill in in the form, I used a spoon to do this
once the concrete was where i wanted it to be than i held the lamp socket in place and put 4 BBQ sticks through the form and around the socket, just above the concrete.
Now its just waiting to do. the concrete dries faster if you let it stand in a bathroom or some room that is hot.
Step 5: Dried
once it has been 1-4 days and you can feel that it is stone hard than you can remove the form.
Now you can smoothen out the corners and make it nicer.
Step 6: Cable
Cut the cable coming out of the lamp in the length where you want your switch to be. than take the isolation off the cable and screw it tight to the switch, do the same thing with the ac plug.
