Eadweard Muybridge, zoetrope (zoopraxiscope) and … Google?

Google's Zoetrope Doodle (04-09-2012) to celebrate the birthday of Eadweard Muybridge

Google's Zoetrope Doodle (04-09-2012) to celebrate the birthday of Eadweard Muybridge

Starting the Arduino Stroboscope, one of my recent projects, I had no idea the ancient technique could still have such universal appeal in the age of full-length 3D animated movies. It was a rather pleasant surprise to see Google celebrating today (04-09-2012) the birthday of Eadweard Muybridge, the stop-motion photography pioneer, with a special animated (obviously) doodle. The static snapshot of the doodle does it little justice, you need to head over to Google and click that “play” button in the middle to see the iconic galloping horse animation play out. Well, OK, trotting – I’m not much of an equestrian :). Read the rest of this entry »

Brushless DC (BLDC) motor with Arduino. Part 3 – The Stroboscope Project


It has been all dry theory in the Brushless DC (BLDC) motor with Arduino series up to this point. This is where it gets to be more fun. If you’ve just arrived, please check out the previous two installments:

  1. Driving a three-phase brushless DC motor with Arduino – Part 1. Theory
  2. Brushless DC (BLDC) motor with Arduino – Part 2. Circuit and Software

In this final part of the trilogy I am describing the hardware part of the stroboscope project and the making of the zoetrope animations themselves, in hopes that my visitors can take this further and come up with their own animations, which I would absolutely love to see. More details below! Read the rest of this entry »
