Our friends at Adafruit just mailed me something remarkably cool. Click the picture to visit their project pages and learn how to do this yourself.
The picture you see above is the result of a Raspberry Pi persistance of vision (POV) project similar to the Magic Wand we featured here a few weeks back, where moving lights are photographed at a slow shutter speed to produce a still image. This one’s more sophisticated and requires a bit more kit (a 3-colour LED rope, hula hoop and bicycle in particular – you can buy all the electronics you’ll need to make your own, including the LED rope, from Adafruit, but you’re on your own for the hula hoop and the bike) – and the results are outstanding. There are instructions and code at Adafruit’s project pages, along with some more pictures.
Phillip Burgess, who put the whole thing together, says: “Total project time, starting from zero Python experience to having a working demo, photographs and a tutorial, was about two days.” Brilliant stuff.
On a related note, Limor “LadyAda” Fried, the founder of Adafruit, is currently up for Entrepreneur Magazine’s Entrepreneur of the Year award. Please head over and vote for her; she’s doing simply amazing things for electronics, hacker and maker education, and we’re very proud to know her.
