I was wondering around Ikea one day and thought ‘This lamp looks oddly like a skirt!’ (Image from ikea site)

50 bucks later, I was putting the leafs of this beautiful lamp together…

…into a Tutu!

And since Knappa is a lamp, of course it needs to light up! I picked some programmable light strip to go inside the lamp.

And to spice it up, I added a Dance Move Detector and cleaned up the circuit. I used:

  • SparkfunArduino Mini Pro 5V
  • Sparkfun ADXL335
  • Adafruit NeoPixel Digital RGB LED
  • USB cable (to plug into external battery pack and power the system up )

This is definitely a more obsessed prototype among all other things I hotglued together. But hey, if you plan to dance around with your circuit, everything must be secured!

Next, code up the accelerometer do some dizzling light effects! Soon enough you realize that you need a standing table to debug a tutu! I let the colors swirl slowly when the lamp is still, and do an abrupt change when a hop is detected.

I brought this to the Burner Halloween party and here are some live actions :]
