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!
Adafruit provides an Arduino library for interfacing with the LED strips, and
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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
