static electricity

Explain in your own words the phenomenon of static electricity and in doing so, define using metaphor or analogy the concept of electricity. Do this all in about 4-5 sentences.


Static electricity is on the surface of objects/ people. It is composed by electric charge. The static charges will lose once the it is quickly neutralized by a discharge. For example, in the morning, our hair will be flying and stick to the brush when we use a plastic brush fix hair in very dry environment. It is because the hair and the plastic brush have separated positive and negative charges. When the brush touched the hair, elections was moving from hair to the brush. Then static electricity phenomenon happened.


How would you make an electromagnet from materials around your house?
What experiment in the Getting Started With Electronics book did you most want to try at home and why?


I want to try the "electroscope" example. I think the method maybe useful for my thesis projects exploration. I am very interested in blow the paper open in a jar. I was thinking I can write something on the paper so that to make the project meaningful.

And on Getting Started in Electronics-Natalie

Static electricity is an electric charge build-up on a surface often caused by an imbalance of electrons or protons. Metaphorically speaking, it is like an ant pile. All the ants are just hanging out bringing food to the hill when…BOOM…shoe on hill…massive disarray! Utter chaos! Ants everywhere! Then…eventual recovery.

How to Build an Electromagnet 101:
1 steel nail
1 copper coil
1 battery
Wrap copper coil around nail. Attach coil leads to battery ends. Nail is now magnetic.

At home…it’d be fun to make an electromagnetic generator/ motor.

Electricity Questions

*Static electricity is the power generated as a surplus or decrease in the amount of electrons go from one object to another, usually movement attracts one to another. The energy is released when an opposite of two charged objects make some sort of connection between the two surfaces. The release in energy can be a large amount or just a small amount small in touching a door handle and large as in lightning. Electricity is the term described to the process of moving the electrons from one location to another sometimes visible but not always. The flowing movement could be seen as the electricity to describe its tendency.

To make an electromagnet in my house I would use an iron nail, and wrap a lot of wire around it and then attempt to run a electric charge through it using a battery. The experiment most interesting to me was the foil experiment to test and see if an object was an insulator or a conduit where the foil moves up or down in jar. To see the foil move would be the interesting portion.

Kelsey and her response

electricity comes potential energy, and the tension between the positive and negative electrons. So if you're wearing wool socks, and you're shuffling your feet on a shag carpet. Your body had built up a store of energy that is seeking to be released. It releases itself through a conductive medium-ie. a door knob-which hurts.

If by electromagnet you mean something that attracts electricity I would get a balloon and a little metal rod, and release the energy from the balloon to the rod. If you mean a magnet powered by electricity then I don't even know where to start.

The project that struck me the most was turning the coin into a battery for the LED. A coin in so readily available, that its interesting it can be made into something as useful as a battery.

Static Electricity Dicity

Static electricity is usually caused by the irritation of electrons stored within an object. A good example of this is rubbing your foot on carpet and then touching an object that is conductive with protons. The electrons are attracted to this source and flow directly towards the positive energy.

Making an electromagnet from home items would not be hard at all. Finding an acidic base such as a lemon or something similar would be used as the container. From here you would need conductive metals that attract protons and electrons. You would then create an electrical flow when fully circulating the loop.

Out of the book the one assignment that I would love to do at home the most was the last one, the interactive street light assignment.

Blog question on electricity

Explain in your own words the phenomenon of static electricity and in doing so, define using metaphor or analogy the concept of electricity.

Static electricty happens when electricity is stored in a conductive material (like socks) by way of friction. The friction encourages positively charged ions to move to the conductive material which is negatively charged. When the positively charged object/material comes in contact with a negatively charged object the charge is released. The energy released is known as electricity.

How would you make an electromagnet...

I could use a nail, some wire and a 9v battery to make one. If you wrap the nail in the wire and put the wire to the + and - of the 9v it will create a current through the nail and make it magnetic.

What experiment would you like to do...

I didn't get to look through all of the experiments in the book but I'd like to do an experiment using servo motors.

Static electricity was defined in the book as being caused by mechanical friction, such as the charge that builds between wool and amber as they are rubbed together. It happens less in places with high humidity because water absorbs charge, so it leaks away faster from the agitated material than it otherwise would.
I couldn't remember off the top of my head, but the illustrated electromagnet used a coil wrapped around a nail insulated with a straw; a magnet is rubbed over the coil to create an electromagnetic field.
I most wanted to try the experiment with the motor made with the lightweight nail, because I didn't understand how it would work at all, despite how I was supposed to, selon the book ....

Static electricity is electricity that is not moving. The electrons become stored and are released and move freely when a conductor is introduced. Electricity is the movement of electrons from different atoms as well as free electrons that are either attracted or repelled and give off energy. This energy can be used to light lamps, power laptops, or if you rub your shoes across carpet, and then poke your friend (or frenemy) you can shock them.

To build an electromagnet I would use a 9volt battery, a copper wire, and a nail. Honestly I don't have those materials laying around my tiny apartment, but it would still be cheap and easy to obtain materials.

I think the experiment on page 22 would be fun to try, a visualization of sound, like many of my teachers have assigned to me as a project.

Answers to Questions..

Explain in your own words the phenomenon of static electricity and in doing so, define using metaphor or analogy the concept of electricity.
Static electricity is the idea of electricity at rest, electricity that is not charged or active. Lightning could be used as a way to explain static electricity, it remains at rest until the potential gradient (in clouds) reaches a level that causes the insulator to break down and fail. This phenomenon produces lightning.
How would you make an electromagnet from materials around your house?
D-cell battery, nail, coated wire, attach raw wire to each end of battery, steel pin or clip, hold it near the magnet and it should pick it up!

Questions on Electricity

Static electricity: By two objects of different materials rubbing against each other, electrons are gained or lost, giving the objects either a positive or a negative charge. The objects then attract opposite charges. The best metaphor to describe the concept of electricity is the water example. The water pressure is the voltage, the tap is the resistor, the stream is the current, and so on and so forth.

An electromagnet can be made from an insulated copper wire and an iron core, like a nail. If you wrap the wire around the iron and attach the battery to the wire, it will become magnetized and create a current.

I would really like to try to make the electroscope and play around with insulators. I think that being able to do this experiment would really solidify my knowledge on electricity. Plus it seems pretty cool to be able to make something move without directly touching it.

I still have a great deal to learn about electricity, and it wont come easy, but I hope this is something I can get a solid grasp on.

monday 08/29 blog

Static electricity: Friction, chemicals, or other processes strip electrons from a surface, creating a positive charge. Because these electrons are not moving, we say it is a static charge. Another surface may have electrons added to it. When a connection is made (such as touching a doorknob after walking on carpet), the electrons cross the gap to "even out" the charges. This doesn't really happen on humid days because the electrons can leak into the moisture in the air.

Home electromagnet: Wrap some wire in a coil around a steel nail, and attach each end to a 9v battery. The nail acts as a magnet as long as power is applied.

Coolest experiment: I thought that testing the conductivity of various materials by using a home electroscope sounded pretty neat-o. I like the idea of actually seeing the like charges repel each other.

Intro to Arduino and Electricity

Reading the basics to both electricity and the Arduino project gave a basic understanding and knowledge of the principals at play for both. The handwritten style of the electricity reading seemed very odd and was appreciated to give a different look. However the style seemed distracting at times, generally though well written and a good context for electricity to begin with. The Arduino intro seemed equally adequate in illustrating certain points and necessary beginner information. My opinion is biased though since I am already familiar with both basics for the readings.

And a Circuit Board

In another life I would have been an electrical engineer....not because I proclaim grand intelligent, but because electricity is (forgive the juvenile colloquialism) "super cool".
I appreciate the handwritten nature of the text, and I appreciate how the information is presented because I "get it". Bring on the circuit boards.

"August 2026: There Will Come Soft Rains"

At first glance and reading of the article I expected an expression of future advances in technology. It took several sentences for me to fully realize that this house was alone. After reading and getting the apocalyptic message and understanding what generally is going on in the article several notions stuck out to me.

The attachment we place on inanimate objects that we personify as this whole article does to the house and objects within. The thought and emotional attachment we as humans have for certain things and object which don't every or can't express the same attachment to ourselves. The fact that we can't even get that emotional or devoted attachment to one another and can not really see how much something/one means to us. The notion of caring and feeling that expression is very difficult to explain correctly to correlate.

A power section was the reference to the dogs death. A very sad section where as from a perspective of a human that this animal couldn't be helped. Why didn't the dog jump up and take the food from the counters? My dog if we forget to feed her once she will just up on the counters and take food. Does this house prevent this? What is the role of being completely helpless. Seeing exactly what you need right in front of you and some force is preventing you from acquiring what you need. Is it ourselves stopping our self or something actually there. A combination of the two? What causes our inaction and our willingness to give in and give up to death. Maybe the dog was so used to being automatically feed and sustained that it forgot how to act and how to be. How to fight, how to get for oneself when the free lunch is done with and can't be sustained anymore?

The lack of the fighting or even knowing if death is there. Are we better off dead or a quitter then trying? If you do give up as an individual would technology or even loved ones in the end, "know that we were gone" sometimes not. Then questioning the point of continuing on and why we do what we do. Continuing on towards this unknown march while we fight or don't fight for a life that will end.

Bradbury Short Story

I'm a fan of Ray Bradbury's stories. I remember reading a lot of them in middle and high school, however I hadn't read this one before. I really liked it. I really enjoy science fiction, especially anything regarding the future, robots, and even apocalypse scenarios- hey this story had all of that! Well the apocalypse is more implied here by the absence of people, But I'm always really fascinated with the notion of the world that we've built around us filled with technology and machines. It can function without us, but only to some extent. at some point that technology is reliant on us.
There is this show that I love to watch on the history channel called "Life After People". and its talks about what would happen to the world around us, if one day all the people just disappeared. It shows how buildings would decay and crumble, how the animals would survive on our leftovers, and technology would stop functioning and even cause disasters without our maintenance. This story made me think a lot about that. Even if humans aren't around the world will still function and eventually nature will take the earth back- all traces of the civilization we built and our scientific discoveries will eventually be buried as the world grows over our existence.

"August 2026: There Will Come Soft Rains"

I found the short story very captivating. Although you know that the outside world is gone you wish the whole time for someone to come in to the house, for a life to be made better by what this structure is doing. I got excited about the dog, but was quickly disappointed at the idea that he was not needed by the house, only that the dog had a need. The fragility of life is no match for that of the mechanical, but, there is no use for the mechanical without life. I now realize the object of the class to create things that are operable with human interaction, it is inspiring really.

Getting Started in Electronics Ch. 1

First can we discuss how bizarre it is to read a book handwritten on line paper? No, but seriously, I really enjoy the organization, hand drawings, and frequent Radio Shack references. Much of the introductory chapter was review from my high school physics course, but it's always good to have review. I certainly remember memorizing V=I*R, etc. The study of valence electrons was also a review from high school chemistry. Since there was an assignment on page 15, I thought I'd try it here. 25 words or less- The "motor" is created by a circuit where current flows from 9 volt battery to nail and coil and electrons are attracted to positive contact. On page 16 is a different take on something I'm very interested in, LED throwies! http://graffitiresearchlab.com/projects/led-throwies/ With a small cell battery taped to an LED and a magnet, you can throw light onto a metal building, bridge, etc. to add a colorful light display. I hope to learn a lot of other cool things I can do with electricity like our lemon battery!

Dailey's Bradbury Pensees

I hate short stories, but this one was good- some writers I think have a sort of synesthesia with words, because you can feel them coddling them, kneading them like bread and tasting them before their put down in ink, sublime syllables inching up your face and through your ears into your brain so you can feel a whole world resting there just in the words. Good writing, but that's probably not the point, or maybe that could be the point, how we could so strongly associate meaning to just printed shapes that we can feel a whole future through abstract lines. That is rather far. This is tangental, but it's just nicely-paced, very mastered in its thinking, a stunningly surprising pleasant read, not sure what it has to do with physical computing other than what we were talking about today, that our art should augment human actions in some way; the automatons of this story could be considered art, functioning on a default without their humans, the absence of their charges a work in itself, their employment in the text highlighting the strangeness of the land, a device to slowly introduce us to a larger, empty world, their demise paralleling the larger one of the city, their last cell similarly doomed. Though I do wonder about the tree surviving. We could also think about the personification of the mechanical entities, how to give something the illusion of life, to augment the message of our own projects. If holograms were accessible, it would be a good illustration.

Kelsey and her Ray Bradbury reading

I enjoyed the reading and I did recall that I've read it before. I liked how obedient and innocent the technology seemed, and how ugly and rearing humanity could be (if you ignore the picturesque) family's shadows frozen on the house when they died. The store reminded me of my own fragile humanity and the fragility of technology-even if it will outlast us.

thoughts on Bradbury story

Within the first paragraph of the story, I was struck by how incredibly annoying it would be if one's household objects communicated aloud via cutesy rhymes. My microwave displays text that says "enjoy your meal", and if it actually spoke, or rhymed, I would throw the wretched thing out the window. Then the voice repeats the date three times. Holy crap, that's obnoxious. Robot mice is just the cutest idea ever, though.

As the story continued, I wondered just how much food the house had stockpiled, and from where it was drawing its power. Solar, I guess, which wouldn't require pumps or pipes or wires.

"But the gods had gone away, and the ritual of the religion continued senselessly, uselessly." That sentence made me think of what was said in lecture today - that our class's focus is on machines that interact with humans, not ones that operate autonomously. If the fictional house had been designed with more emphasis on user feedback, it wouldn't have continued to function pointlessly.

Designing Interactions by Bill Moggridge

A great book about the history of Human Computer Interaction, especially on the development of the mouse, visual interfaces and mental models to consider when designing. Offers a lot of insight to the psychology of users and has interviews with all of the major contributors to the modern computer.

And Something About Soft Rains

"But the fire was clever."
Ray Bradbury, how you use your story-telling capabilities to their optimum. That sentence created an instant pause in the midst of a most bizarre empty house nearing its end. There are moments where the world seems to sit still, and I think he captured that in that one sentence. Delightful.

The people are non-existent, so he turned this electronic house into our "person", we, I think, begins to relate to the house because we are prone to desire to relate in order to understand. But at the same time, it seems so empty and mechanical and still compared to our world of emotions and movement. I suppose that's what makes it eery.

In its very essence, this story, the way I understood it, captures the fleeting nature of things. Like this summer, between traveling and working...BOOM...gone. The only difference is this story gives no relief or hope. It is rather dismal, but that is the way of Bradbury's genius. He makes you think and consider the possibilities of this world and what it could become and the influence we have on it in our current time despite writing stories about the "future".

Beginning Arduino: Chapter 1 Introduction

The preface to this book seems like this guy knows what he's talking about, and knows the correct writing style for beginners. Since we already discovered the blinking program during our in-class exercise, Chapter 1 was mostly a review, but it still makes me confident that we're going to learn some cool stuff. Youtube has plenty of videos and I'm sure I've only scratched the surface of the Arduino art, but I'm also easily pleased. LED lights are my fave! I've used them in my typography course and my ceramics course, and I don't want to end there!
A cute video using Arduino and LEDs can be found here
http://www.youtube.com/watch?v=x7-wtJGhpzE&feature=related

There Will Come Soft Rains

This reading made me feel depressed and anxious. I feel a sense of weirdness that is difficult to describe.

In the beginning, the completely automated environment already gives me a sense of anxiety. Immediately, the thought of letting automatons take over the simple actions in our day-to-day lives makes humans seem inefficient and almost obsolete compared to the machines that can do it better. Then we get to the part of the story where we release that it takes place in a world where humans no longer exist anymore. However, even in the absence of humans, the machines go on working as if nothing had happened, and their efforts are fruitless. However, I suppose everyone and everything has a purpose, and we all exist to serve that purpose, so I guess that in itself is not "fruitless."

The most exciting and also unsettling aspect of this work is the personification of the house and all of its functions. There seems to be this frantic energy all around the house, and its juxtaposition to its lack of inhabitants is the unsettling part. Do you remember the scary feeling of being home alone when you hear strange noises in your house, but it turns out to be nothing? Well the automated house seems like those strange noises, yet they are the ones taking charge and who are not frightened. The roles are reversed.

As far as relating this story to this sensors class, I guess machines, which rely so much on humans for creation, can function way beyond the existence of humans. It's like the poem from the story:

"Not one would mind, neither bird nor tree,
if mankind perished utterly;
And Spring herself, when she woke at dawn
Would scarcely know that we were gone."

A machine could never fathom its existence, and would not really give a damn if it were to perish. However in this story, the house struggles so hard to keep intact and tries to save itself, even when any and all hope of usefulness has gone. It struggled so hard just to exist, and nothing more. The house trying to cling to life seems like it would be exhibiting a human characteristic, but at some point, even a human will lose the will to live if there is nothing to live for. As much as an automaton can be programmed to behave like a human, sometimes logic varies.

August 2026: There Will Come Soft Rains

This short story brought about tall questions, questions that we cannot truly answer, only think about. When will we have gone too far? When does technology outstrip humanity? This fictional piece, and others, even like the movie Wall-E, are good because they force us to think about the far future of our civilization, not just the near future of our convenience and desires. What I found most interesting about this literature was the constant near-human presence, the personification of the objects, the almost motherly qualities of the house. When the dog died, it was devastating because I immediately became attached to anything left living, anything we could identify as part of our family, our world. Until we can establish a global mandate of shared responsibility, this path does seem inevitable, a robotic world that no longer needs humans, like iRobot, (although impending doom is always much nearer in fiction ie. 1984). It's possible that some expressive art piece could call this to attention on a national level, or some eco-friendly well-designed ad campaign, or even an artist who transfers over to politics. But monumental change cannot occur until those with the power to change will agree collectively to give up their comfort for the better of others that they've never met, and that is going to be a challenge.

Ask the questions0822 2011 by Dan Dan

Describe a piece of art or an interactive experience that used electronics as a medium that made an impression on you or that you remember.


Two and a half years ago, I saw a artwork online. It's an interactive light environment art work published in London.

The work showed many huge lighting bulbs(Larger then people) floating in the air, which are pure illusion created by projectors. The color of the light would be changed constantly while the people was moving around the lighting bulbs.


Describe any previous experiences with electronics and sensors.


I don't have too much experiences with electronics and sensors. The only experience I had this summer is that I designed an storytelling design project for AIGA 2011 Seed Awards Exhibition in MODA (Museum of Design). I used camera to work as an "motion sensor" in order to capture the motion and shadow of people when they were interactive with this piece.


If you not in Digital Media and taking this class, what are your reasons for taking this class and what do you hope to make?


I am from Graphic Design. My work is about question/experimental design projects. It is more like design methodology research. Right now, I focus on the exploration of the means/ways/methods of storytelling. I think this class can give me another perspective about storytelling which is very different from the perspective in design area. Also I am interested in interactive topic. I believe there is a big potential to generate a new way of thinking which will make an influence my research.

Cory Arcangel's Nintendo hacks were what originally caught my attention of digital media being an art form of itself. His Super Mario and white clouds got my attention during a young age when I didn't know too much about contemporary art. Because of these pieces I started to do self investigation of other forms of digital art and became fascinated with experiential interactivity.

I have a small computer science background but most of what I know in terms of coding and electronics is primarily self taught. A majority of the stuff I have worked on is USB or "plug and play" and alot less circuit based. I spent a small amount of time working on Arduino, but not enough to be comfortable with it yet.

The digital media major is something I'm hoping will expand what I already know and also teach me a large amount of what I don't know. I'm primarily interested in unusual methods of interaction at the moment.

Kelsey's class intentions, experience and post.

I saw a Tony Ousler piece at Art Basal that waited till the viewer talked near enough to it. It unsettled me quite a bit, but it definitely stuck. It was a person with an egg head getting crushed by a couch and she was talking to herself and to someone else the viewer could not see in the room.

experience: I made a piece, last spring semester in Advanced Experiments that used the Arduino Lily Pad. I sautered a the circuit together, but got help with the programing. I also used the little gizmos in the supply room like the sonar sensors and the piezo speakers.

I'm taking this class because I think technology is an extremely relevant topic today. I also think it is an interesting medium for my work, and I'd like to become more affluent in it.

Sensor's Week 1 Introduction Questions:

The most recent interactive experience that used sensors in art that I witnessed was in the Spring by Adam Grayson using the Kinect device. Where using your body you controlled yourself and an avatar of yourself on screen.

Experience with electronics in the previous Art and Technology classes from the Junior level. Combining computer components to create a functioning computer but not actual hands on creating and combining the actual individual small components. Once I watched recent graduated do some soldering work from the Art and Technology and Sculpture majors.

I expect to learn different skills and explore various topics for the digital arts field.

And Day 1 Questionnaire

There are two interactive electronic pieces that impressed me, both made by the group The Fun Theory. One, was a staircase turned into a piano, so when you stepped on the stair it would mimic the sound of a piano. The second piece was a trash can that would create a cartoony noise of an item falling an incredibly absurd distance. The idea behind both of these projects was to improve a city. With the stairs, more people starting taking the stairs instead of the escalator, and with the trash cans, people would actually be more aware of throwing away their trash.

Trash Can: http://www.youtube.com/watch?v=cbEKAwCoCKw&feature=related

Previous Experience: I played a computer game when I was a kid where I had to correctly complete circuits once. Besides that…none.

Expectations: I’d really enjoy learning enough to make fun/surprising electronic pieces around campus, not unlike The Fun Theory’s work.
An example of interactive electronic art that made an impression on me was a piece that I've read about and seen photos of, but haven't seen in person. It was a giant robotic snake-creature that was articulated and could move around and be controlled by the audience. It also had flamethrowers in its mouth. The audience could approach it and, using controls built along its length, make it move around and breathe fire. Although this seems like a lawsuit waiting to happen, it was pretty much the coolest thing I'd ever heard of.

I don't really have any experience in electronics. I soldered once before, but it was a crude, sloppy job and I don't really remember how to do it. I've been reading the Beginning Arduino book but I haven't done anything hands-on yet.

I'm not in Digital Media (I'm in photo). I am taking this class because it sounded really cool, although I don't know what kinds of projects are reasonable or unrealistically ambitious. (Obviously I won't be making a giant firebreathing robot.)

Impression- First thing that came to mind was a screen at an aquarium that responded to how much people moved by populating it with sea life, kids seemed to like it a lot.
Experience- nothing formal, able to jump start a car.
To learn- I had some trouble with Christmas lights last semester, I'd like to learn more about, I'm not even sure, step-down converters? using power from an outlet, and what the symbols in electricity mean, because I remembered some from chemistry but am not able to apply it. I still don't want to be a gallery Artiste, maybe something applied, maybe something else that I should figure out.

John Powers was one of my undergraduate sculpture professors at UABirmingham, he has a vast background in different types of sculpture and has wanted the chance to teach a sensor-based class for a while but we never had a huge desire from students for it on campus. His work is inspiring and he says that it has opened many doors for him so I've always wanted to give it a go. I have no prior experience aside from soldering, and very basic (high school) electronics skills. I am eager and very persistent though!

1st post

Describe a piece of art...
Here's two videos I've seen recently that are relevant:



Describe any previous experience...
Not very much electronics experience but I do have experience using a soldering iron, flux, and wire and taking apart electronics (although not having very much luck putting them back together). I would give myself a 5 out of 10.

If you are not in Digital Media...
I am in graphic design but I'm interested in user interaction and how to engage users in ways beyond typing and looking at screens (and even beyond touching screens which is becoming the new norm). I want to learn to use and program sensors to animate objects and create new experiences in real life.




Sensors questions

Describe a piece of art or an interactive experience that used electronics as a medium that made an impression on you or that you remember.

In a museum by the Savannah College of Art and Design, I remember a professor's piece that had an inviting grid on the floor, projected from overhead. When I stepped into the projection, the game started and I was suddenly working to try and trap a virtual ball by walking around the projected space, and my actions affected the game.

Describe any previous experiences with electronics and sensors.

The last time I worked with circuits was an honors physics class in high school.

If you are in Digital Media, what do you expect to learn in this major?

I expect to learn a variety of skills and expand my knowledge of the growing field of technology in order to incorporate it into my own self-expression in art.

If you not in Digital Media and taking this class, what are your reasons for taking this class and what do you hope to make?

My Electronics Experience

The only electronic art piece that comes to mind at this very moment is a piece done by a previous digital media student two years ago at what I'm guessing was their senior show. The piece projected a white screen onto the wall. When somebody walked in front of the projector, it created a silhouette of the person on the wall, and a descriptive word appeared over their heads. Sometimes i believe it was a hat instead. The words were accompanied by comic giggling coming from a speaker nearby. I honestly never really gave any thought to what the piece meant, but it was memorable because it made me laugh and I found myself interacting with it for longer than I had engaged with any of the other pieces at the show. I found it incredible that a piece so seemingly simple could be so engrossing. It was interesting to keep interacting with it over and over because the user got a different result every time. I believe I stayed long enough until it cycled through its databank of words/hats.

As far as my experience with electronics and sensors, I don't really have a whole lot. I remember when I was little, my parents bought me one of those Klutz kids kits that dealt with circuits and electronics. I think it included a battery, some wires, a motor with fan attachments, and a light. I remember that it was really entertaining for me and I enjoyed learning how it worked. As far as recent experience, using Processing was a nightmare for me last year. I really had a lot of trouble understanding how to build programs from scratch. I was able to look at a program and understand how it worked, but the other way around proved problematic for me. I'm hoping to gain a better understanding of Processing this year and maybe not want to throw my computer out the window.

Being a Digital Media major, I'm hoping to really develop the conceptual side of my work. I feel that last semester, I really didn't do a lot of conceptual thinking, and I think my work suffered slightly. I'm hoping to also be able to apply what I learn in this class to real-life scenarios. While I don't really plan on being an experimental electronics artist, but I would like to be able to fix electronics and be somewhat knowledgeable. I just hope that class is enjoyable and that I can become immersed in it.

Lu answering the initializing questions

Describe a piece of art or an interactive experience that used electronics as a medium that made an impression on you or that you remember?
Can't remember the name of the art piece, but I saw it on 2010 art basel.
It is a weird twisted shell-shape sculpture that kind of integrates both mechanical and biomorphic features. When you get close to it, it makes weird industrial but soothing sound.

Describe any previous experiences with electronics and sensors.
When I was a undergrad, I did experiments under instructions of a teacher with simple computer chips. When I was in Virtual Environment Research Lab, there's a virtual patient project we were working on. I was working on the speaking interaction and another member was working on the physical interaction. The physical interaction was that the mannequin was installed with an electronic arm so when people talk to the mannequin as a patient, the patient arm will move.

If you are in Digital Media, what do you expect to learn in this major?
Just want to make something new and fun, something more interactive than computer and bringing more "art-like" interaction.
Because the computer interaction is highly highly limited with mouse and keyboard.
the way of interaction although shapes human's mind, it also highly limits human's mind.
Hopefully, through trying some electronics, I can make "more natural" HCI.
I also feel that the electronic can be a chance to bring virtual world and real world together.
And that blurring the boundary or infuse some "soul" into the industrial world, is the critical part I really care about.

Introduction Post


I remember last semester when I was taking Advanced Experiments and we talked about wearable technology, we looked at some dresses that moved and lit up in response to the model's body. I thought that it was pretty neat that our clothing could become interactive with us, and I wonder if all clothing in the future might be like this.





Last semester I worked briefly with Audrino, but didn't utilize it for my final project. I would say I definitely need refreshing on how it works.

I'm not in Digital media, but I'm taking this class because I enjoy learning about digital media and making projects using technology. I'm also really interested in learning new technologies so that I have the knowledge for myself, and also that I might one day utilize it as a teaching tool in my classroom when I become a teacher.
