(This video is Akinori Goto's. We added the interactive elements to this idea.)

Concept

Zoetrope ( Repeated ImageSequence) + 3D Modeling + Light

Find a new animation of light

By developing the basic concept of the classic Zoetrope, we made our own fantastic modeling referring to the works of 'Akinori Goto’.

In order to implement animated images in 3D printing structures, we used light instead of cylinder devices to modernize them into unique light works.

Detail description

One sequence of operations was rounded into frames. There’s a principle that when 3D objects are spinning circular, there’s a thin light shooting them. And it looks like all frames are moving making an animation.

Also we designed this artwork to resemble the shape of the record player.

The user can experience four different 3D animation zoetrope by changing the LP plate. In addition, people can adjust the speed of the rotary plate with the knob on the right of the main body.

Step 1: Principle and Composition

inspired by 'Akinori Goto'. Interactive Elements (When a person presses a button, different light animations come out of the beam depending on each button, adding four different modeling and light animations to create a variety of looks).
[Modeling] Sketch out what kind of animation we wanted to show. A total of four (bird, ballet, single lady, person) modeling configurations.

Step 2: Product Composition

Step 3: Materials

using program

[window] Processing 3.0(To play the video according to the button)
[window] Arduino ( Pressing the button of the processing code )
[window.exe program] SPARROW( A program that links processing and Arduino )
[mac OS, window] Rhino 5.0 ( A program we used for modeling )
[mac OS] Adobe after effect CC ( For light images )

Step 4: Modeling by Rhino, Illustrator

A total of four models were produced in the following manner. (Bird, ballet, rolling person, single lady)

First, find image sequences (image continuous operation).
Work as an illustrator, one by one, with a pen tool.
Draw a circle on Rhino.
Place the line drawn by the illustrator exactly on the circle.(Note: Be sure to take a clear look at the position when you bring it in. If the position changes, it will not work continuously, or the height will become louder.)
Connect the lines one by one.
Give thickness to all lines. (Approximate: horizontal line: 0.3 mm / vertical line: 0.4 mm)
7.Convert the file to the .stl file and move it to the 3D printer. (It does not matter if you have a good printer, but if you want to use a small printer, split it into 4 or 8 parts like we did.
8. Attach each part and place it on a circular spindle.

Step 5: External

Designed to resemble a record player. It was made easily using fomax and acrylic.

Detailed figures and configuration are shown in Step 2.

Step 6: Internal

참고: turntable 참고한 내부 모델링 https://www.thingiverse.com/thing:2031323

based on Nema17 42mm stepping motor (200 steps per round) as I have already owned them. The pinion gear is the widely available 16-teeth aluminium GT2 gear used in 3D Printers and the main gear is 3D Printed 90-teeth GT2. The belt used is 200mm (100-teeth) GT2. Additionally you need 1x 608ZZ ball bearing, M8 bolt, M8 nut & M3 screws-nuts (nyloc nuts). The table surface is the D180 round glass for the Kossel 3D Printer (I have ordered D220 size glass but at first received smaller one, later the correct-sized was received and I did not know what to do with the first).
All parts were printed using PLA and 0.3mm nozzle/0.15mm layer (I do prefer longer in time but higher quality printouts), and you need 3 "GlassHolder.stl" copies. The flat holders surfaces can be used to fix glass to holder using clips (not shown on the photos).
