A zoetrope is a pre-cinematic animation technique where a series of animation frames are placed inside a spinning cylinder. Slits in the cylinder make the frames of the animation visible for only a fraction of the second creating an animation. My 3D zoetrope relies on the same principles but instead of flat 2D frames I am using 3D models and instead of the slits I use a strobing LED light to illuminate each frame for a fraction of a second.

You can see a full write up and video of the zoetrope in action at:

Great job, really amazing.
I added a stepper motor and 5 power leds, synchronized by a small ATtiny processor.

Great! Thank. I can't built the motor - don't have tools. Can I buy it on amazon or ebay?

Is there anything cheaper that can fit as well?

Comments deleted.

Wow, very impressive and cool idea! That's real 3D cinema.

Very clever and original. Any chance of the Blender file for the horse (he asked cheekily)?

How about a 3D Monty Python animation for the next one?
The title sequence for the BBC's "Holy Flying Circus" had a huge Phonotrope. (titles start ~2:05)

Got to see this at the last NYWMF. Very cool. http://i.imgur.com/Vp9Dq3c.jpg

Any plan's on selling the motor all set up?

Definitely considering it. Need to work out the details.

So a pony walks into a bar and asks for a cup of hot tea with lemon.

The bartender says, "This is a bar. Don't you want something a little stronger?"

And the pony says, "No, thanks. I'm just a little hoarse."

Wow, that is great!

I had one of these when I was a youngin

Wow this is amazing! I would love to try to make this. It might be a little out of my league though to set up those electronic's! Have not attempted to make anything like that before.

Congrat's on being featured, well deserved!

Beautiful and surreal. Excellent work.

Thanks! I just added the parts for the hub and motor mount as well.

The is really lovely and I hope it gets featured (beyond a front page collection). Excellent work.

Nicely done, I especially like your write up with such a complete description of the process. Thanks for posting. Russ
