You will need a few tools. I used:

• Japanese saw
• Screwdriver
• Right angle ruler
• Glue
• Sandpaper

Materials that you will need:

• led light bulb
• light bulb base
• wire with switch
• glue
• wood Board 28*28 mm

First of all, you will need to cut lots of wood cubes.

My cubes will be 28 мм. You can make any size you want. Additionally, I cut 18 mm cubes

I measured and cut, measured and cut. If you have circular saw, you can use it. It will be much more faster and evenly.

When we cut all cubes, we need to sand them.

You can use a sand machine (it will be much more faster), or you can use just a piece of sandpaper as i did.

Now i will make a base for the led lamp. I made base 85*85 mm.

Then i make a first layer of my lamp. I fixed cubes with glue.

I waiting until the glue dries up. Then i drilled a hole for the wire. 

Connect wire with bulb base

And fix with screws to the base

Warning! Use only LED bulb. Led lamps do not heat up much.

Now i'm making all other layers. Place the cubes in any order.

Whatever you like.

For the top of the cubes I made a stand out of paper clips. it will seem that the cubes are hanging in the air

That's it! The lamp is ready and you can enjoy your beautiful lamp!

I hope you like it! Thanks for watching!

P.s. maybe you are interested how can i removed the bulb when it will stop working:)? 

Please don't worry! It can be easily reinstalled in 5 seconds 😉
