Final Project
What will the Zoetrope do?
A Zoetrope is a mechanical device that creates
the illusion of moving pictures, based on a spinning cylinder in
which slits are cut. As the cylinder spins, the user looks through
the slits at the pictures across. The scanning of the slits keeps
the pictures from simply blurring together, and the user sees a
rapid succession of images, producing the illusion of motion.
My plan is to produce a 3D Zoetrope that makes static 3D
sculptures appear to move and come to life explaining the basic concept and principles of animation.
Using strobe LED lights and a number of sculptures, each a little different then the last, on a rotating platform the 3D Zoetrope will recreate the effect of looking through slits of the original zoetropes.

What tasks need to be completed?
- 3D print characters
- Mill disc and stand
- Speed and strobe synchronization
Questions?
- How much current can an ATTiny handle?
- What amplifier(i.e.. transistor, buck puck, MOSFET, etc) to drive bright white LEDs ?
- Using the motor of the turntable?

Evaluation
- Sync of motor and strobe
- Design and stuff LED strobe boards
- Use Fab Academy output device speaker board then design, develop, and code program for syncing motor and strobe lights.
- Design and stuff voltage divider board
- Design and stuff voltage divider board
- Complete design, molding and casting of characters
- Design and cut platform to hold the complete zoetrope
- Design and cut two-sided board to hold characters on one side and on the opposite side to hold the magnets
