Fabrication Final

I combined my fabrication final with my PComp final – to make a sugar box interacted with p5. Firstly I laser cut it.

photo-dec-13-10-50-58-pm

I divided it into different areas, so it can contain different kind of sugars.

photo-dec-13-11-08-44-pm

After being cut, it’s like this:

photo-dec-13-11-09-45-pm

Then I sticked them to be a box.

photo-dec-14-12-10-06-am photo-dec-14-12-14-47-am

In order to rotate the cover of the box, I sticked two pieces of wood with the Servo, so it can be heavy enough to move the cover.

photo-dec-14-2-54-32-pm

Generally, my PComp final works like this (and the box part is my servo mount):

ICM Final: Wheel of Fortune (Unfinished)

Basically, my idea is to make a wheel of fortune. Since at first, I assume our PComp and ICM final projects should be combined together for our winter show.

I didn’t write the code through website but it’s in my laptop, so I recorded a short video.

My wheel of fortune works like this: it rotates as we activate it, and it stops when we press the mouse (or press another key, still adjusting).

And my p5 is connected with my arduino, which controls the Servo. Only PINK, ORANGE and BLUE will activate the Servo to rotate, which brings different colors of sugar into my cotton candy machine. And other colors will lead to nothing.

If the right color is activated, it will pour the sugar into the machine, and my Cotton Candy machine will start to work.

The Servo will pour different colors of sugar into the machine, and people who activated it can make cotton candy themselves.

Right now I only have this draft version of both my p5 and arduino codes. I’ll add more decorations and functions to my p5, like I may activate the camera so that people can see themselves’ faces at the center of the wheel – which may be a good way to attract people. And I’ll add music to make the wheel more like a casino game. Also, I’ll define different colors different meanings, so even if people can’t get the change to make cotton candy, it will be less boring.

 

Fabrication Week 5

This week we need to hold two different materials together.

Firstly I thought about making a golden edged handkerchief, just as what is like what the characters use in Northeastern China’s traditional song-and-dance duet. But I realized the cultural gap, and it would be too hilarious to be an assignment, and there may be no one who can get my point.

%e4%ba%8c%e4%ba%ba%e8%bd%ac

Then I wanted to 3D print a sword, and laser cut a sword scabbard. But then I found I couldn’t book 3D printing machine during final time.

%e5%89%91%e9%9e%98

Finally I decided to make it as simple as possible: to make a Windmill.

photo-dec-05-5-37-45-pm

Firstly I tested different materials and I chose the postcard for our winter show.

photo-dec-05-5-38-35-pm

I cut a small wooden stick and sanded it to make it flat and smooth.

photo-dec-05-5-42-11-pm

I needed to cut the postcard to make it a square first.

photo-dec-05-5-46-02-pm

I cut and folded the post card.

photo-dec-05-5-47-53-pm

When I fold it to be a windmill, I stick different parts together.

photo-dec-05-5-56-50-pm

After glued it, I needed to hold it for a while.

photo-dec-05-6-01-02-pm

Now I need to connect it with the wooden stick.

photo-dec-05-6-02-21-pm

I used a needle to get across from the windmill to the wooden stick.

photo-dec-05-6-08-18-pm

At first I thought I could sew it together, but then I realized that the string could not work if it’s thiner than the needle – it would get through the whole stuff.

photo-dec-05-6-12-34-pm

Fastening is supposed to be the hardest part. I considered for a while and tried different materials, finally I decided to weld the needle.

photo-dec-05-6-12-45-pm

I cut the needle to make it shorter using the high temperature, then I welded it to fix it.

photo-dec-05-6-21-26-pm

So it works like this:

windmill

In case sometimes the gif doesn’t work, here’s the original video:

It’s simple and childish I know. But this is the only thing which finally came to me that could work : P

Fabrication Week 4

This week our assignment is to make enclosure. I decided to make a music box, which I have been expecting for a long time. I bought a music movement with the song La Vie De Rose. When it arrived, I found it really tiny.

photo-nov-23-2-27-27-pm

I found a piece of wood, and cut it into small pieces to fit my movement.

photo-nov-23-2-27-52-pm

I wanted to make it as tiny as the movement, so I only left a thin frame to it.

photo-nov-23-2-27-01-pm

I cut it depending on what I’ve drawn.

photo-nov-23-2-35-05-pm

And I sanded it to make it more flat.

photo-nov-23-2-53-05-pm

I drilled holes by using the Drill Bits in shop.

photo-nov-23-3-05-21-pm

I drilled several holes to fit my movement’s size.

photo-nov-23-3-26-56-pm

But if I move my movement, it’s really ugly and disgusting. “Is it honeycomb briquette?” My friend said. I smiled.

photo-nov-23-3-39-59-pm

Finally I decided to give it up and made it again from scratch. This time I asked a second year student, Phil, to teach me.

He told me to choose a larger piece of wood at first. He said we need to leave more spaces, cuz we are always losing our wood while we cut, sand, and drill it.

photo-nov-28-8-01-19-pm

So this time the wood piece is much larger than last time.

photo-nov-28-8-02-00-pm

He told me to draw a draft on the wood piece. Firstly I need to locate the outline of the movement, then I need to calculate and locate where the circles (which I’m gonna drill) should be.

photo-nov-28-8-06-08-pm

He lent me his Forstner Bit, so I would not drill deep holes like last time. And he also reminded me to clean the dust while I’m drilling.

photo-nov-28-8-11-53-pm

After drilling four holes, it turns out that I needed to drill more.

photo-nov-28-8-20-53-pm photo-nov-28-8-25-01-pm

It’s hard to control the wood when we are not drilling a complete circle. So he told me to drill it super super slowly to keep it stable.

photo-nov-28-8-35-27-pm

After drilling the hole on the side, I found it was hard to insert the hand shank in it.

photo-nov-28-9-29-43-pm

Phil told me to drill a larger circle and a smaller one, so the movement would not move weirdly.

photo-nov-28-9-59-14-pm

After drilling all the holes, I sanded the box to make it smoother.

photo-nov-29-10-20-15-pm

And I laser cut a cover for my music box. Because the song is La Vie De Rose, I chose rose as the image, but since my friend told me that the lines in the image I chose was too tiny, so I also made plan B – a simpler rose image.

photo-nov-30-12-25-47-am

Firstly I didn’t set it to be powerful enough, so it wasn’t cut even after five time of cutting. Then I changed the power, and it worked!

photo-nov-30-12-34-07-am

Finally I sticked the cover on my wood box.

photo-nov-30-6-53-03-pm

And here’s how it works:

Fabrication Week 3

This week we are learning Laser Cut. I didn’t have any experience before, so this is the very first time for me to get in touch with laser cut.

At the first time I made a huge mistake: I booked the 75W machine, which according to my friends, is the worst choice for new hands.

cut1-2

I needed to adjust everything manually, and I always forgot to change the button from “focus” to “job”, which took me lots of time.

This is how I learned to adjust it manually:

cut1-1

Finally I made a maze, based on a picture I’ve found online. But I’m not satisfied with this little project.

cut1-3

The other day, I found a new piece of wood, and I cut it to fit the machine.

cut2-1

Then I found a picture I like from internet, and I drew the line of the picture in Photoshop, and then I imported it into Illustrator.

cut2-2

The shop ran out of tapes, so I needed to use small ones to fix my wood piece.

cut2-3

After setting up the speed and power and everything, it started to cut.

cut2-4

cut2-5

For fear that it could not cut deeply, I cut it twice.

cut2-6

But it turned out that I was wrong: it’s still not deep enough. When I took out my “Tree”, several parts broke, because the wood hadn’t been cut thoroughly. So I needed to stick my branches and leaves back together.

cut2-7

Finally this is how my fragile tree looks like:

cut2-8

And you can still see the tiny patches on it.

cut2-9

As for why I chose to cut a tree, it’s from my favorite poem back in high school, “A Blooming Tree” composed by a Chinese poet Xi Murong.

“May Buddha let us meet
in my most beautiful hours,
I have prayed for it
for five hundred years.
Buddha made me a tree
by the path you may take,
In full blossoms I’m waiting in the sun
every flower carrying my previous hope.
As you are near, listen carefully
the quivering leaves are my waiting zeal.
As you pass by the tree
without noticing me,
My friend,
upon the ground behind you
is not the fallen petals
but my withered heart.”

Fabrication Week 2

This week we are making 5 duplicated stuffs. I decided to make five dices.

Firstly I picked appropriate wood (plywood is not a good choice for making small pieces) and measured sizes.

dice1

Then I cut the wood into pieces, as I expected how my dices would be like.

dice2

Then I polished the wooden pieces, so their surfaces would be smoother.

dice3 dice4

Once again, I polished them on abrasive paper to fix the tiny defects.

dice5 dice6

While polishing them on the machine, I accidentally broke my nails – it didn’t hurt so much, but it scared me.

dice7

Finally I got the basic shapes of my dices.

dice9 dice10 dice11

Now it’s time to drill holes on them. Firstly I need to make sure where the holes should be.

dice12

I tried different machines. Firstly I tried this one, but it was hard for me to control the specific position where to drill, and it was also a trouble since I needed to switch to different surfaces and adjust the machine once I finished.

dice13

Finally I decided to drill holes manually. And after drilling all the holes, I polished them again.

dice15

So here are my dices!
dice17

Fabrication Week 1

This week we are making flash light.

Because I’m still confused with (and afraid of) cutting woods, I chose to make my flash light with paper cups.

I got my materials very easily: two paper cups from ITP kitchen (I ruined two at the first time when I tried, so I took four actually), dark red knitting wool from soft lab, LED and a small wooden stick from shop, and a button cell battery from a mini flash light I had.

cups

Firstly I cut two cups and drilled a hole on each one by scissor. Then I used the knitting wool to get through the bottoms of each one to connect them together. Then I insert the LED through the top hole.

photo-oct-29-6-32-28-pm

Then I painted a piece of paper to red, and cut it into strips.

photo-oct-29-6-31-56-pm

And I painted the lantern to red, and connected it to the paper strips and the small wooden stick. Then I sticked one side of the LED with the battery, and covered this part with the left part of the paper cup.

photo-oct-29-7-11-27-pm

Finally, my flash light works like this:

Happy Halloween!!!

Pcomp & ICM Week5 (Synthesis)

Last Friday, we combined our Pcomp and ICM projects together.

I chose my ICM sketch “rainy day”, in which mouseX controls the curtain – if mouseX moves, the curtain will be closed and the window will be covered. I added a analog switch to replace mouseX, so it works like this:

After a while, my partner Lindsey and I decided to add some funny elements to my little project:

It’s a great experience to combine them!

PComp Week4

I designed a simple system using Force-Sensitive Resistor. I connected the FSR with the length of delay: if I press the FSR, the music will go quicker, or it will go as usual.

Here’s the video of my project:

Firstly, I imported the reference form (pitches.h). I tested for several times and found out the tones I wanted (do, re, me, fa, so, la, si, do), then i arranged them a singing pace.

If the value of analogRead changes, the length of delay will change as well, so the music will go faster.

Here’s my code:

#define speakerPin 9
#define forceSensor A5
#include “pitches.h”

int myNotes[] {523,587,659,698,784,880,988,1047};

void setup() {
// put your setup code here, to run once:
pinMode(A5,INPUT);
pinMode(9,OUTPUT);
tone(speakerPin, 2000, 5000);
Serial.begin(9600);

}

void loop() {
// put your main code here, to run repeatedly:

int forceSensor = analogRead(A5);
Serial.println(forceSensor);
delay(1023-forceSensor);

for (int i = 0; i<8; i=i+1){
tone(speakerPin, myNotes[i], 500);
delay(analogRead(forceSensor));

}

 

PComp Week3

The public facility I hate most recently is the elevator in Tisch.

elevator2

It’s a big trouble especially during rush time. We can hardly tell if the up and down buttons are pressed or not, and we never know whether or not the floors we need has been selected.

elevator1

Sometimes it doesn’t go up untile it arrives the lowest floor, and vice versa. But the elevator lights are not capable to transmit such information, so it may waste large amount of time for us to get to the right floor.

elevator
The limitation of its storage and speed also cause inconveniences.
