Make a POV display with a desk fan

 Making a successful persistence of vision device usually involves either the device holding the LEDs to move quickly, or the person holding the device to move it quickly. The former is preferable, and a great example of an Arduino-based POV display has been documented by Instructables user "duboisvb", whose POV device is mounted on an ordinary desk fan. Then by using a small Arduino-compatible board, seven LEDs, a hall-effect sensor and other circuitry the device can detect rotations and display the LEDs for greatest effect - for example:

That's a neat and simple POV project, and you can find out more from here. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

 When making your own project that needs a small, Arduino-compatble board - check out our 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.
