10/16 - Skycraft Scavenger Hunt - Jen and Madeline





Skycraft Scavenger Hunt                                Jen Herrera and Madeline Morales

Please take a picture of each item on the scavenger hunt using your phone. You may work in pairs. You need also to take some notes getting serial numbers and label text so that you can learn more about the item and its specs when you get home. Post small sized pictures and text describing objects on blog. I need enough information to know what it is. Have fun!

Post is super long so page break: (click read more to see post, or this post will eat the whole front page)

Manga Part 4 156-195

1.    What is an example of a semiconductor device?
 Transistors, Diodes

2.    Why is silicon used in the manufacture of semiconductors?

It used as a raw material and it is refined product.  The refined of this material is almost 100% … 99.999999999% 9x11 . It causes to increase the electrical conductivity of semiconductor.

3. Discuss the difference using an example of the difference between and N-type and P-type semiconductor.

The electrode of P-type in semiconductor is Anode, which is included negative property, and N-Type is called Cathode, which is included positive property.

4.In your own word describe what a diode does and the role of N and P type semiconductors.
N-Type of semiconductor goes to hole of P- type of semiconductor; this    connection becomes a wall that prevents the electrons’ moving. When the holes of P-type and free electrons’ of the N-type of semiconductor are attracted to each other, cause to enhance of the potential barrier and current will flow.

5.What is rectification?
It is kind of property that allows current to flow in one direction.


6.    What causes color in an LED? Give and example of what causes a particular color.
The color of LED depends on raw materials of semiconductor, which emits wavelength of the light. Such as light in traffic signals, mobile phone digital camera. Luminescence of light emitting in diodes doesn’t import heat and it works with efficient energy that why there are variety and used in different ways.

7.What is the relationship between base current and collector current in a transistor?

Base current is when the current that flows from the base to the emitter and base current also current from the collector to the emitter is called collector current.  When the base current flows, the collector current will also flow.

7.    What are the advantages of a transistor over a switch?
Transistor can be used in replace of contactless switch, and it is not similar to switch to have a physical contact. Transistor it doesn’t wear out is less to fail has more control while in turn on and turn off rapidly.

Mini project/sketch

For this mini project I have to decided to go off of one of my previous experiments

instead of just using the fade sketch (like i did here) I am creating something similar to the last exercise we did in Ch.4. I am attaching the IR proximity sensor and running the same sketch, just modified a little for one LED. Along with the LED, a small wire sculpture will be inside of the box. The intention is that as the viewer moves closer to the box, the brightness of the LED increases, and the shadow of the wire is cast on the surface of the box.

So that's the physical break down, the "how does it work/ what is it made of" part. Conceptually, this is an idea I have been working with for almost a year. Overall, my work deals with memory, and things related to it such as identity, relationships, connection. This

I'll have pictures/video soon, I'm having a terrible time uploading them to my computer.

Tom Igoe

Tom Igoe's personal background in theatre is an interesting combination with the use of digital media and technologies to connect with audiences. I found it difficult to relate to Igoe, simply because he himself didn't identify with any true area or medium in regards to his work. He is neither an artist nor engineer, yet his work incorporates components of both. He himself describes the need for both mediums in order to form ideas. I did like his thoughts on the process of design – "application should drive the technology." It allows you to be limitless in possibility, though it is unfortunate that you must be brought back to reality based on the hindrances of technology. I also agree that some of the most talented people are those able to create innovative designs without the use of technology to fuel their ideas. I was also surprised to see something so regular as Dance Dance Revolution to be an example of physical computing; the term itself sound super high-tech and complicated, when the reality of it was just simply a melange of good visuals and easy to follow cues.

Manga Guide to Electricity part 4

1. Diodes and Transistors are examples of semi-conductor devices.

2. Silicon tends to be cheaper than other materials. It also has a wide temperature range and has a high purity of 99.99%

3. N-type semiconductors have negative electron properties. P-type semiconductors have positive properties, they are missing an electron.

4. Diodes consist of p and n type semiconductors. This allows electrical current flow in one direction with a wall in-between them.

5. This allows current to flow in one direction.

6. The raw materials in the semiconductor creates the color, by changing the raw material you can change the color.

7. Base current is when current flows from the base to the emitter. Collector current is when current goes from the collector to the emitter. The collector current thus gets bigger than the base current.

8. A transistor does not get worn out easy, its also doesn't fail, and can be more precise when controlling it.

Manga Questions part 3

Manga questions Part 3
1. Heat is made when current flows through a resistance (rising temperature). Its similar to waiting for your favorite cpu game to update. As the bar gets closer to 100 percent its get slower(resistance) and you become more anxious and ready to play (heat).

2. Its warm near an incandescent lightbulb because of Thermal Emissions. This happens when temperature is increase which emits thermal energy.

3. A superconductor is not a insulator or a metal. It is like a perfect conductor for electricity because current flows through it infinitely without decreasing in strength. Magnets can be used to make superconductors. Examples of when they are used is in maglev trains, MRIs, NMRs, and magnetic confinement fusion reactors.

4. Ampere's Law is that Magnetic fields are created when electricity is in use. They form circular patterns around wire.

5. The two wires will attract to each other because the two currents create two magnetic fields that'll combine to create one large one.

6. The magnetic fields will disappear because the repulsion is generated, zeroing out the wires.

7. The motors we used turns by use of the the Left and Right hand rule. Which explains how force acts when in a magnetic field. With the motor the left hand rule determines the direction of the  current.

ANNIE KLOPP | Paragraph on Tom Igoe Article

http://we-make-money-not-art.com/interview_of_to/

Tom Igoe, an NYU professor, is a very common name in the physical computing community. He is part engineer, part artist, yet regards himself as a humble "neither." His experience in theater has influenced his work today, which "centers on physical interaction related to live performance and public space." The structure of Igoe's classes is very "hands-on," asking students to get creative with creating their own projects and applying the skills that they learn.   He says that he follows his former students' careers in art as much as possible.  He gives quality advice to students in the article and then finishes off by talking about some projects that he is working on and some of his favorite contemporaries.

The most interesting part of this article was his advice to students entering the professional world, so I have chosen to outline these pieces of advice from Igoe here:

1.  Art is most successful when other people's ideas are involved besides your own.

"You learn so much from working for and with others that strengthens your artwork that you'd be a fool not to collaborate or work for others from time to time."

"The people who do best in this field figure out very quickly that they can't work alone, and that they need others to make a difference."

2.  Don't just be an artist; be an entrepreneur. 

"I think the most successful ITP alums take an entrepreneurial approach to their careers, whether its seeking new opportunities in large companies, starting their own businesses, seeking ways of getting their artwork shown, or a combination of all those things."

3.  Learning physical computing helps you learn to troubleshoot, not just necessarily how to make devices. 


"Even if you never touch hardware again after the intro class (and many don't), there is somethign for you to learn from spending a period thinking about how the body meets the bits." 

4.  Optimum art training gives artists visual sensitivities.  


"Art training at its best gives people a heightened sensitivity to sensual cues (audio, visual, tactile, etc) and in some cases a strong ability to analyze work from an aesthetic perspective."

5.  Visual ability alone isn't going to make you successful.


"You also need the creativity and attention to detail of a good engineer, the insight of a good social scientist, the pragmatism of a good business manager, and more."

House Hold Appliances Manga Part 1

House Hold Appliances
1. Ceiling Fan
It uses 35 watts
at 20 hours per day 365 day per year I'd be spending $30.66 at 255.5 kWh a year

2. Clothes Dryer
it uses 2790 watts
at 1 hour per day 50 days a year I'd be spending $16.74 at 139.5 kWh a year

3. Microwave
It uses 1500 watts
at 30 minutes a day (over exaggerated) for 180 day a year I'd be spending $16.20 at 135 kwh a year

4. HD TV Television
it uses 234 watts
at 4 hours per day 365 days a year I'd be spending $41.00 for 341.64 kWh a year

5. Video Game System

at 5 hours per day 365 days a year I'd be spending $7.88 for 65.7 watts a year

Questions
1.The TV the Microwave and the Games System cannot be in one outlet, it exceeds the wattage for the outlet.

2. Electric Current is the rate of charge flow at a certain point in a circuit, its measured in coulombs per second (amperes)

3. It was difficult to find this information because I live in a huge apartment complex.

Wave Shield

We worked diligently on the waveshield. After soldering we formatted our sd card and added the sound files onto it. However the computer wouldnt recognize the waveshield, we werent sure if it was the waveshield or the sd card itself.

Below is a picture of our waveshield:


New ideas

Exploration of Synethesia

Use a thermo sensor, a proximity sensor or ultrasonic range finder, and a monitor....the "colors" of the person will be shown on a monitor...possibly in the shape of a person or maybe taking up the entire screen
---a pseudo mood reader
----sounds assoc. with mood?
----
----concept: how people react to things they're told even though it may not be true...hence the title pseudo....the person will be given a random range of colors and a chart describing what the colors mean together in terms of their mood. They will not know its a fake mood reader.
----the effect false information has on someone
