Since the start of the World Cup, VPS’s robo octopus Paul has been predicting the outcome of the event’s football matches. But how exactly was Paul made?
RoboPaul is pretty popular. Heat mapping information from the VPS site, which shows the parts of the site that are most used by VPS.net customers, reveals that the RoboPaul icon on the homepage is getting a lot of attention.

Round and round and round they go! 24 ultra bright smart LED NeoPixels are arranged in a circle with 2.6″ (66mm) outer diameter. The rings are ‘chainable’ – connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you’re ready to rock.
