DIY rainbow lamp brightens up your home; pot of gold not included

Miguel de Frutos

While those multi-colored glowing desk lamps can make a nice addition to a room for extra ambience, there is one downside: you rarely get a lot of choice in how the colors cycle.

Miguel de Frutos has his own solution: An RGB lamp made out of a long strip of LEDs that he can control with his computer. The lamp itself is a simple wooden frame with the LED strip attached to the sides.

To control the LEDs, Miguel uses some simple homemade software that allows him to pick the color of each LED. Using his software, Miguel can choose to show a mix of colors or set the lamp to display a smooth gradient. The patterns display in real time too, so you can see what works on the lamp as you tweak it.

A Bluetooth connection with the computer and an Arduino Pro Mini microcontroller relays the color settings between the computer and the lamp itself (Miguel says that any microcontroller will work, so you aren't stuck using an Arduino board). The resulting creation is quite a conversation piece—assuming conversation's your thing, that is.

If this colorful lamp isn’t quite your thing, you could always pick up the stackable Tetris lamp.
