Step 1: Making A Lamp Shade

The lamp shade is made using straws. I followed a simple cubical shape however different designs can be made.Arrange the straws and apply hot glue in the way shown in the image.

Step 2: Repeat this step thrice

Now you have the four sides of the shade. Use Hot glue gun again to join all the sides together from the edges. Put a thick wire inside two straws from each end and fill the straw with hot glue so that wire gets fixed in it. This will act as support for the shade so that it can be fixed on the lamp pole.

Step 3: Making The Stand

The stand for the lamp is made using simple wood board and a regular wood pillar. Draw a square on the board and cut it out using a hacksaw. This square will act as the base for the Lamp. Drill a hole in the centre of the square as well as the pillar and use a self tapping screw to secure the pole with the base. This will also form a base to support the LEDs.

Step 4: Fixing LEDs on the lamp

Take the RGB strip, cut it and fix it on the pole vertically. LED Strips are self adhesive. No extra adhesive material is required. It can be easily cut using scissors. NOTE: Whenever cutting LED Strips, cut it only from the marked line indicated by the manufacturer on the strip or you will end up damaging the internal wiring, leading to non-functional LEDs. After fixing the LEDs on the pillar, you need solder all the connections using a soldering iron. RGB LED strips are already marked with R, G, B & +12 in which R, G, B refers to ground of red, green & blue respectively and +12 is the common positive voltage.

Step 5: Connections

So connections are to be done such that R, G, B & +12v of each strip fixed in the lamp are connected in parallel so that every LED goes ON simultaneously with same color. Once LEDs connections are done we will end up with four wires R, G, B & +12v. To change the brightness of the LEDs potentiometer will be used which will modify the voltage value supplied to the LEDs. Potentiometers will be connected with R, G, B as shown in the circuit below. Once the connections are done. Just fix the shade over the lamp stand and you are done.
