The HypnoLamp Project

The HypnoLamp Project

Many factors helped birth the HypnoLamp: At Toorcamp 2012, I learned to program microcontrollers. Jeff of Olympia Circuits blessed me with addressable LED strips, at the aforementioned event. Jeff was also at the Portland Mini Maker Faire, showcasing (among other things) glass Ikea lamps with LEDs inside. I decided to build my own version!

From the project creator:

Q: Why didn’t you use [insert other microcontroller here]? It’s better!

A: I used the Adafruit DC Boarduino. At the time, I felt this was the best choice, because:

  1. I had prior experience with it,
  2. Adafruit provides an Arduino library for interfacing with the LED strips, and
  3. The beautiful algorithms use floating point arithmetic (which is more conducive to creative coding than using integers), in HSV color space, which is converted to RGB and pushed to the LED strips at 60 updates per second (effectively 60 FPS), and it runs great, with no performance issues, and we can all go home early.

Programming the lamp was a joy. Each animation was tweaked until it was hypnotic, yet subtle enough to accent the room.
