This is simple easy to make DIY project for weekend. It just need some basic tools like drill machine, pliers and screw driver with some of your creativity.
I got one wooden pallet piece from a scrap seller at very low price, I bought two wall L clamps from a hardware store with screws just :).
In Indian rupees it costs me less than 100 rs so in dollar it may be a 2 dollar project (60rs approx = 1 dollar).
I created an extra transformer less 12V power supply to power a LED strip and then taped it using double side tape with the pallet to get a different effect :).
