  Very neat! I want to make one, but I'm sure my kids would stick their fingers in there...

  But I have to ask, why was an Arduino necessary for "critical timing"? I would have thought that the Prop could have handled the whole lot standing on one of its eight heads.

  No, the arduino only generates the pwm for ESC/Motor

  Surely the Prop can do that PWM thing as well ?

  ÄÄhhhmmm. Yes of course. But the Prop rotates 40 times/second and i've enough problems to get power to the ring ;-)

  Beautifully done! As Peter suggests, you could certainly use the Propeller for your PWM output (and button input) as well. Add a hall-effect sensor on the shaft and you could have the Propeller automatically set the speed.
  
  Edit: Ahh! I see. The Prop is on the rotating part!
  
  Edit edit: well, there's a way around that! Put the motor and ESC in the rotating part too!

  I see. Fair enough.

  Ok, that's the next challange, who's first ?
  
  @ all : Thanks !

  FYI, your project is today's top staff pick in the daily instructables email!

  Really Awesome! And good job combining the Arduino and Propeller. This would be a very cool practical for a movie or something, and if it were possible to stop the image from rotating, it would be really neat as a communication device. I really need to check out the P8XBlade2 for a project that I am working on.
  
  One note, the link for the "microSD Breakout" appears to be broken.
  
  Thanks for sharing.

  the rotation is only a feature, i thought the video looks better !!!
  
  the link for the "microSD Breakout" is repaired !!!!
  
  
  Many thanks to Jon and also Seairth

  Awesome, especially the Death Star!!!
  
  Could you have used a BASIC Stamp instead of an Arduino?

  Magnificent. Love the 3d printed ring for the LEDs.

  Wow. Well done! (BTW, Earth rotates counterclockwise, as viewed from over the North Pole.)

  The data transmission and PWM frequencies seem low compared to the APA102 - no?
