What is it?

This is a persistence-of-vision toy. You mount it via the hole in the middle to either a dowel or a pivot and spin it around while it's turned on. The LEDs on it blink in patterns you can't see when it's standing still, but while it's spinning, it will trace out patterns in the air.

Why did you make it?

This is an evolution of the Tiny Blinky wearable. The circuit is the same, but arranged differently. The firmware differs, but as with the Tiny Blinkies, while it's turned off, the battery draw is negligible.

Great little toy!

Received it fast! But then again, I'm in the next state over. Looking forward to getting the programmer and pogo adapter so I can program my own patterns! The only suggestion I have is to locate the hole closer to the battery so it is balanced. It's kinda hard to keep it balanced on the tip of a pen before giving it a spin. I think swapping the locations of the button and hole would work perfectly.

Pure wizardry . . .

When I'm teaching kid with Arduino, it is fun to use blinking LEDs and persistence of vision to demonstrate both how fast computers are and a little bit about how the eyes (and brain) work. This simple little gadget is a great way to get their attention and interest. Here is an example of how I do that: http://www.makersbox.us/2013/12/arduino-beyond-blink-how-fast-is-fast.html
