Make your own POV globe with Arduino

 Arduino enthusiast Chris Mitchell has created a fantastic persistence-of-vision device that doesn't require a lot of hand-waving - instead eight RGB LEDs are fitted to a ring that rotates at ten revolutions per second, giving the illusion of an 8 x 50 pixel LED display. Controlled by a Freetronics LeoStick the POV globe can display a variety of messages or graphical effects, as shown in the following video:

That's a fantastic item which looks great and you can make yourself, so review Chris' website for more information. And for more, we're on twitter and Google+, so follow us for news and product updates as well. Have you made something great and want to share it with the world? Post the details in our Project Showcase forum, and you could even win a prize.

So what is a LeoStick? It's the Arduino Leonardo-compatible board that's cheaper and smaller than the original:

 Apart from being one of the smallest Arduino-compatibles on the market with USB, it also has an onboard RGB LED and piezo which can be used a knock sensor and various tune and sound effects. Plus you can add extra circuitry with the matching protostick! For more information and to order, click here.
