Articulated desk lamps are somewhat complex mechanical objects that require an industrial context to produce, given the usual components of factory made metal parts, springs, screws, and cast plastic elements. I wanted to design a version of a desk lamp that could be produced in completely non-industrial contexts, with only naturally available materials and resources--excluding the light bulb and wiring itself, sadly.

a small amount of wood: a 2 x 4 will be more than enough. I used less than half a square foot of 3/4 inch thick plywood. Cut and notch it as pictured, and you've got your basics done!
a couple rubber bands. The nice part about all this is that you can adjust the tension of your lamp by just adding another rubber band. You can also easily replace them--unlike the springs and pieces in your usual desk lamp
a light bulb and electrical socket
a sheet of printer paper
Cut the wood pieces--on a bandsaw if you're lazy, and by hand if you're really hardcore about it. Wood piece 4 is a small piece that slots into wood piece 3 after everything's done to constrain the range of motion of the lamp

I'm glad you like it! If you're trying to build it, good luck :)
The cuts are pretty easy to make on the bandsaw--and not too tough if you have a nice, small hacksaw and draw out your notches before you start cutting.
let me know how it goes!
