This is a pop-up book that I made to represent the city of Shanghai. When you open it up, all the buildings pop up. When you press the button, the lights go up. When you open up the black flip, you can see a bunch of flowers and a thank you message. When you spin the handle, my name will appear.
It cost me 2 weeks to make the project from prototyping to finishing the whole project. When I was working on this project, I have encountered so many problems.
I spent a whole week on making the oriental pearl tower. At first, I got a template of a pop-up sphere online. 3D Snow Ball Template
I was pretty satisfied with the shape, but I then found that because of its radial shape, I could not make it to support another same one above it.
Then I wanted to make a hollow sphere with interlocked pieces. Therefore I used 123D Make to generate a template.
However, after it is cut out by a laser cutter, I found it totally impossible to lock the pieces together.
So I checked the instruction in 123D make and it did not make any sense.
I tried to fix it on myself through Adobe Illustrator and made a file like this.
But it turns out that due to the thickness of the paper, the shape is impossible to be formed in this way. If the size of the rings were larger, they will be assembled more easily.
Finally, I gave up the idea of making a hollow sphere and designed a solid interlocked sphere.
But the offset was set too large and the paper could not be tightly locked together, so I had to change the numbers and make another one.
I made 2 identical spheres with flat-formed LEDs sticked to it and made the circuit with conductive tape. The ends of the tape went through the paper and goes to the back of the base. To pull up the spheres, I used threads.
The oriental towers was not standing exactly on the fold, I made some “box supports” that can stand as boxes when the book is opened into 90 degree. But I fully opened the book, in this way, I created 2 more folds off from the central fold.
I did not discard the first kind of sphere, I made 2 smaller ones and created Shanghai Exhibition Center. I added a pop-up cylinder around each sphere.
I designed all the buildings with Adobe Illustrator and sticked flat LEDs and conductive tape inside them. I also made the circuits into patterns so that they can be projected when the LEDs are lit up.
When making the Illustrator design file, I created dash lines to make it easier to fold the card. However, when the dashed lines are made in Illustrator, the laser cutter would not cut anything out. Marcela helped me edited the file in rhino and got it to work.
When making the Jinmao Tower, the thing that I worried about most was the stair-shape of the top of the building. I combined rectangles and isosceles trapezoids, put them in sequence and fold them with mountain fold by valley fold by mountain fold… It can be folded but cannot be pulled up when the book is opened. So I added a stick that can pull back the top when the book is folded and push up the top when the book is opened.
These 2 buildings were standing in the same way as the previous 2.
When making the Shanghai Tower, I found it impossible to form that twisted shape. So I sticked 2 pieces with 2 different angles to make it look like twisted.
I had a large battery box to power the LEDs, I put it at the back and I had to stick some foam to the bottom to make sure the identical thickness. I sticked black paper stripes to hide the foam.
For the switch of the circuit, I once wanted to use nocturnal circuit to light up the LEDs when it is dark. But the transistor of the circuit could only control a circuit with 1.5 voltage, and it could not work with my circuit that needs a much higher voltage. Then I wanted to make a slider as if the city lights up with a persons control of time span, but the conductive tape could not touch each other tightly and therefore would not be conductive even if you slide the witch to where it should be able to close the circuit. I really had no other ways and I just made a paper “button”.
I got the mechanism of the iris online and made this to hide may signature and add more interaction.
