Need a new night light? Friend? Lover? Deity? Why not all four?

Introducing HeadLamp.

The focal point of HeadLamp is a styrofoam head stuffed with LEDs for a bright glow, on top of a body made from a flexible air conditioner exhaust tube that softens the bright LEDs, creating a pleasing gradient of rainbow light. Recycled food containers are used as spacers inside the tube to hold the LED strip securely in place to minimize bright spots and shadows. A button on the end of the tail provides a quick way to cycle through a library of color patterns. HeadLamp’s brains consist of an ElectroMage Pixelblaze LED controller, which comes with a WiFi controller for easy access to the LED settings and a library of color patterns from any device, an innovative live editor/compiler that allows for easy programming, and a hardworking community of makers contributing to an online repository of patterns. (An optional Pixelblaze Sensor Expansion can make HeadLamp sensitive to sound and acceleration.)

HeadLamp is a fun offshoot of Headbot, a self-balancing robot that I helped design as a student on the South Eugene Robotics Team (FRC Team 2521 – see our Instructables page here).
