Newton`s Cradle Research

Newton's cradle, named after Sir Isaac Newton, is a device that demonstrates conservation of momentum and energy via a series of swinging spheres. When one on the end is lifted and released, it strikes the stationary spheres; a force is transmitted through the stationary spheres and pushes the last one upward. The device is also known as Newton's balls or "Executive Ball Clicker"

ACTION

If one ball is pulled away and is let to fall, it strikes the first ball in the series and comes to nearly a dead stop. The ball on the opposite side acquires most of the velocity and almost instantly swings in an arc almost as high as the release height of the Last ball. This shows that the final ball receives most of the energy and momentum that was in the first ball.

Newtons cradle 5-ball system. One ball is pulled away and is let to fall; it strikes the first ball in the series and comes to nearly a dead stop. The momentum of the first ball disappears and reappears as the momentum of the last ball as it rises into the air. This shows that the momentum of the system remains constant.

The impact produces a shock wave that propagates through the intermediate balls. Any efficiently elastic material such as steel will do this as long as the kinetic energy is temporarily stored as potential energy in the compression of the material rather than being lost as heat.

Intrigue is provided by starting more than one ball in motion. With two balls, exactly two balls on the opposite side swing out and back.

Newton's cradle 3-ball swing in a 5-ball system. The central ball swings without any apparent interruption.

More than half the balls can be set in motion. For example, three out of five balls will result in the central ball swinging without any apparent interruption.

While the symmetry is satisfying, why does the initial ball (or balls) not bounce back instead of imparting nearly all the momentum and energy to the last ball (or balls)? The simple equations used for the conservation of kinetic energy and conservation of momentum can show this is apossible solution, but they cannot be used to predict the final velocities when there are three or more balls in a cradle, because they provide only two equations to find the three or more unknowns (velocities of the balls). They give an infinite number of possible solutions if the system of balls is not examined in more detail.

Double Pendulum research

Part of my idea, I wanted to do a double pendulum lights(or a swinging sticks sculpture lights) it really its my very first idea and wanted to do the most, however it seems too complicated for me to do it, I mean the ambition is good, but over ambitious is not something I would want to be either, so after quick research on them I decide to give up on this, because really its over complicated and requires some extreme precise engineering to achieve to effects, so...yeah, i hate to ditch ideas but i had to do this.

Double Pendulum explained:

In physics and mathematics, in the area of dynamical systems, a double pendulum is a pendulum with another pendulum attached to its end, and is a simple physical system that exhibits rich dynamic behavior with a strong sensitivity to initial conditions.^[1] The motion of a double pendulum is governed by a set of coupled ordinary differential equations. For certain energies its motion is chaotic.

Idea expressing

These sketches are just my few first ideas for my lights, I want to make something that can move, I am always fascinated with movable objects.I came out with few ideas for this lighting system.

One is just a wall lamp with three shells connected together and you can move the shells, I dont like the idea the second I thought of it, but its an idea nonetheless.

The second one is newtons cradle, this desktop toy is quite a fun thing to watch and kill time, the problem that its too small (toys on the market), if i ever going make this Im gonna make it big

the third one is swinging sticks, from the movie iron 2 i discover this toy, its really eye catching and i wanted one ever since i saw it, however it cost 200 dollars each, I dont think im going to have one anytime soon, but if i could make it myself it would be a great achievement for me. 

Great Mind-Yuri Suziki

Yuri Suzuki, I first know him was because he gave a talk at the uni last year, and i was just amazed with his work as a artist and designer, although most of his interactive work are music based and I dont know music hat much, but I dont need to understand what he does to know how impressive he is in terms of an interaction designer. 

Also his London tube map radio, I first did not know it was his work when I saw it in Design museum London. I immediate understand that how complicated it is to make a radio wiring in to the map of London tubes, and how much time it took to etch the circuit boards, he really is one of my fav designers now.

Arduino mini project-Andriod controlled RGB Leds

Thanks to MKE. I am able to achieve this small trick, I follow the tutorial on the MAKE. website and did this Android controlled LEDs, its capable of changing colours by touching the colour board on the screen of the phone, with the cable connection, the Arduino takes the signal and power from the phone, while the LED strip takes the external 12v power supply, I am able to change the colour of the strip to anything I want.

The MAKE. turorial is:

Arduino mini project-RGB LED

This is the right thing I want to do for my final outcome, a changing colours led lights, its fairly simple yet have a great result, just some coding with a strip of 12v leds the possibility goes great wild, for home lighting and decoration purposes.

Here the lights are still being controlled by the Arduino board along which is programmed to change the colours consistently with a frequency, the thing I want to do is with a controller, or your smartphones/devices, to achieve remote controlling the lighting. 

Great Mind-Dunne & Raby

Dunne and Raby, pretty famous designers in the world, with their designs being great materials for debates and mind boggling, the debates I meant isnt the negative but positive way. their works always has greatly encouraged people to think about our future life we gonna have and we want to have, the difference between these two are often mixed together or not being thoroughly considered.

Their works are fairly simple, dont really have any complicated electronics wiring or complex engineering on the physical object, i think its because what they really want to do is to express the ideas they have and communicate with the world, and from what I they did it and did it successfully!

Arduino mini project-Traffic light

For this mini project, things are simple and straight forward, simply tell the LED when to turn on and off, its a things that I could write the program on my own but I still decided to post it because my final idea has something to do with this sort of layout, and it does give me idea of how am I going to approach it in a better way.

code for this project:

int ledred=10; 
int ledyellow=7; 
int ledgreen=4; 

void setup()
{

 pinMode(ledred,OUTPUT);
 pinMode(ledyellow,OUTPUT);
 pinMode(ledgreen,OUTPUT);

}

void loop() {

digitalWrite(ledred,HIGH);
 delay(1000);
digitalWrite(ledred,LOW);
digitalWrite(ledyellow,HIGH); 
delay(200);
digitalWrite(ledyellow,LOW);
digitalWrite(ledgreen,HIGH);
delay(1000);
digitalWrite(ledgreen,LOW);

Arduino mini project-74HC595

In this particular  mini project, Im learning the use of a dedicated micro-controller which is labelled 74HC595, for this chip has 8 bit register and memory, it does something quite useful when you have too many things to control at once while only having one board. 

In this case im controlling 8 LEDs at the same time, if i would do it the other way, my Arduino board wold be full of wires and hard to use, this is when the extra microchip comes handy, I am able to use only 4 pins to control 8 LEDs with the help of 74HC595, although this isnt something I would use for my final outcome but its always great to learn new skills, it would be useful some day.
