Process 1.13
Post-crit reflection and conceptual ideation:
One thing that was noted and I felt really worked with the piece was the uncanny ambiguity of the direction and exact interpretation of the installation. (ignoring the lube for now and referring to people's reactions after it was wiped off) It became an experience for the viewer that made them think about these objects that are symbols of desire, sexuality, arousal, taboo in a sense, and often the subject of male gaze. Which we then took out of context of an actual physical female body and put them on display to be touched. Some said that this created a dissociation and since they were breasts, but weren't really a woman's breasts, they saw no reason why not to touch them.
But, there was also an element of feeling uncomfortable to touch them, or creating a situation of deeming whether or not it would be socially acceptable to touch these breasts that are lit in an alluring way. This is where the decreasing amount of available light came into play, because as the viewer was getting closer to them, figuring out whether or not they were able to touch them, or if they wanted to touch them, their actions were less and less visible to other onlookers. This part creates an interesting interplay that I didn't previously think about: what the interacter's actions are vs. being watched by onlookers, and how those actions are affected by the visibility of those actions (less and less light to totally darkness). The total darkness achieved by when someone is actually touching the breasts also creates a usually brief, but could be however long as desired, moment, where no one can see what the interacter is doing and the only active senses for the interacter are tactile.
With this, several concepts come up that one could talk about when I think about the piece: indulgence, taboo, unrealized or realized desire, ability to act freely, freedom from judgment, in general the potential for exploitation when no one is watching, full exposure, exposure as potential for liberating choice or unwanted and forced, acceptable and unacceptable behavior coined against no one would know, acceptable behavior on a spectrum which relates to the space, context, environment, surrounding people, society, personal values/opinions; strange but lighthearted playfulness as a reaction, immaturity and jokes, potential for repulsivity, how comfortable or uncomfortable people are and how it relates to the way they interact with the piece.
Stemming from this uncomfortable/comfortable idea, this iteration has been deemed mostly uncomfortable, intriguing, but in a strange way. What would be interesting is to see how different of a piece it would be if it were construed in a comforting setting. What if we made people feel comfortable with the idea of touching these objects instead of putting them on display in an ambiguous and uncanny setting? How would the two iterations engage the viewers differently? How can you invoke a sense of security and welcoming and intertwine it with the interaction of a new iteration/installation of the piece?

Process 1.12
Notes from crit:
- People said they're gross
- Reminds Katerie of some sort of alarm system
- Shadow changes are interesting
- Think about what shapes are made by shadows
- manger
- crucible
- Alluring, gelatinous, symmetrical, perfect, pranky, edible
- Why do they have to be wet? bad?
- association with wet: ultrasound
- not associations that are unintentional
- ie: slap in the face? when go to touch them, but they're slimy - "punishment" for touching
- Use biofreeze instead (mostly scentless icy hot)
- Has interaction after - first cold, then hot, warming sensation
- Thinking about how it gives off the idea of a trophy to some people
- How people mount trophy kills (animals)
- Hanging on the wall
- expand? could make it more trophy like, if wanted to go that way, glimmery
- if went this direction, mount on varnished, polished wood, with gold plaque
- What if it felt warm and didn't expect it to?
- use warm light (colors)
- make temperature of breasts warmer
- not currently intimate setting or situation or presentation of these breasts
- What's hidden and what's not hidden?
- Fetish
- Salvador Dali and surrealists
- how they deal with women's bodies
- Valley export piece
- Could go an industrial direction - not personable, specimen, medical
- metal, reflection of viewer revealed on front pane of shiny metal
- Implants
- What if displayed or introduced on horizontal plane (shelf)
- Sensor becomes this sort of navel and creates a weird abstracted torso
- Installation becomes body
- Think about the idea of silicon
- NO SLIME ASPECT
- Already a taboo object, and slimey substance on breasts is like a double taboo and it's cold and uncanny, made people feel weird, uncomfortable, want to touch more without slime on them
- Surveillance - surveil/record hands, not face, what people are doing, what would you pick up on
- LED light
- makes people think of hospital, clinical, parking lot lights
- use warmer color lights - how would it be different?
- think about adding or switching for red lights
- How to turn them into comforting objects?
- goes along with the warmth of temp and color
Bird project 1
started by creating a found object bird that I can then animate with moving wings and a motion sensor to make the bird move when people are around. As in it reacts to motion, its response is to fly when people get near, much like a bird in nature would do when feeling threatened. I created this bird out of multiple metal parts that I gathered from thrift stores around the area.
My first task was to create a working mechanics for the wings to be able to flap powered by a stepper motor. Here I have assembled the mechanics with the stepper to make the wings flap by pull of two strings. The design failed since the stepper motor was not strong enough to be able to handle the torque required to life such a weight. I would need to plan the wings in a more seesaw fashion to handle the weight.
Here I have created a longer armature for the wing span and retested the stepper motor to see if it could handle the torque of the wings and it again failed due to the weight. It would turn but would fail on the down swing. I am also unhappy with the distance the wings can move due to the small space the motor is needed to be kept in.
Here is a video of the functioning wings. They are set at 50 speed, if increased once again they fail due to the torque required. I am presently waiting for a higher torque level stepper motor, with that I can probably increase the wing movement and torque specifications to be able to create a more life like wing flap. I will also be attaching extra moving items to the bird, more mechanical, like a turbine rear wing. I want to keep the bird semi nostalgic and he must be created out of "so called" waste products. Items that have been thrown or given away due to their lack of "so called" value.
Manga Questions 156-159
1. What is an example of a semiconductor device?
Grey selenium is an example.
2. Why is silicon used in the manufacture of semiconductors?
Silicon is probably most often used because of its abundance and relatively low cost and it's dependable. It can be of both p and n types. It sounds like it's just awesome and it's fun to play with.
3. Discuss the difference using an example of the difference between and N-type and P-type semiconductor.
They're typically of different materials: N-types have no holes and a negative charge (get it, "N"), while P-types have wholes to allow more electrons to pass through and have positive charges.
4. In your own words describe what a dioode does and the role of N and P type semiconductors.
Diodes, like LEDs, take current from one place but don't allow it to come in from the other. It's sort of like making a magnet because you have to combine both types to make the diode.
5. What is rectification?
Allowing current to only flow in one direction.
6. What causes color in an LED? Give and example of what causes a particular color.
The wavelength of light emitted depends on the raw material used as a semiconductor. Current is passed through the various materials interacting with that park of the visible spectrum to produce a specific color light. Blue LEDs first used magnesium-doped gallium nitride.
7. What is the relationship between base current and collector current in a transistor?
Base current is our initial current we run through the transistor. The collector current builds the energy in the transistor allowing for a larger current to be outputted.
8. What are the advantages of a transistor over a switch?
Transistors act as a go between where as switches are directly connected. They also allow for a steady output of power versus on/off and they're less likely to ware out quickly.

Manga Questions 36-80
2. Contrast the speed of an electron with the speed of electrical motion in one sentence.
The speed of eletrons through a conductor is usually fast whereas the speed of electrical motion like current is typically slow.
3. Briefly explain the relationship between resistance and energy. Use an example from your house.
The more resistance something has, the less energy it outputs as the energy is typically lost in heat. For example my iMac requires more energy to run than does my razor and the iMac usually gets much hotter as that energy is lost through heat.
4. What is the difference in AC and DC current? Give and example of each from your daily life. If you get shocked,
AC = alternating current vs. DC = direct current. My cell phone uses direct current where as the lights in my house as well as the outlets use alternating current. You're probably more likely to be shocked by dirct current.
5. Determine the equivalent resistance of a 6.0 Ω and a 8.0 Ω resistor if …
a. … connected in series.
6.0 + 8.0 = 14.0 ohms
b. … connected in parallel.
(6.0 x 8.0) / (6.0 + 8.0) = 3.428 ohms

Manga Questions 90-116
What is the relationship between heat and electricity. Please provide a metaphor.
Heat is the vibration of molecules. As current is passed through a conductor the electrons bump into the molecules/atoms, which in turn increases vibration and raises heat. One could think of the haunted houses at Halloween Horror Nights with people (electrons) moving through the house (conductor) bumping into the walls and objects inside.
Why is it warm near an incandescent light bulb?
Light bulbs work by thermal energy being emitted via electromagnetic waves, which once the temperature gets to a certain point visible light from the visible light portion of the spectrum is emitted. Because the production is paired with thermal energy, light bulbs exude heat.
What is a superconductor? What are they used for in real life? You may have to look this up. How could one make a metal a superconductor?
Materials typically made of metal wherein they are put into an environment near absolute zero. This causes the atoms within the substance to almost stop moving allowing electrons to pass through with as little resistance as possible. They're used in things like particle accelerators and in magnet separation (which is totally nuts) in making pigments. You can make a metal superconductor by somehow bringing a metallic material (I would assume you could use some sort of a wire?) to near absolute zero.
What is Ampere's Law?
"Ampere's Law states that for any closed loop path, the sum of the length elements times the magnetic field in the direction of the length element is equal to the permeability times the electric current enclosed in the loop."
An example is sending current through a wire to create a circular magnetic field.
Good example imagery: http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/imgmag/amplaw2.gif
If current of the same size flows in the same direction in two electric wires placed side by side, what happens?
The strength of the current is now twice the original.
What happens if current of the same size flows in opposite directions in two electric wires placed side by side?
Both fields created repulse one another and are negated.

Soft Rains Reflection
Ray Bradbury is a really interesting science fiction author with a gift of relating technology to our lives as humans. The story has an incredibly eerie undertone in a post-apocalyptic world; destruction hinter by nuclear warfare. Though the house in the story is completely automated, the interaction with technology is not unlike those in my own. While I do not have a voice that wakes me up, I have an alarm who frantically hopes to awake someone with its singing. The nursery with glass walls is also an interesting case as I have sheets of class that change colors and create fantasy, though they are not wall-sized. Overall it's interesting to note how many of the technologies Bradbury is suggesting have come into existence and will very likely be available in all consumer homes in the near future. My overall attitude towards my dependence and integration with everyday technology is there are a lot of things that technology makes easier, such as access to running water in my home and the entire epitome of knowledge available to me 24/7. I don't personally believe the amount of dependence on technology I currently have is necessarily a problem or the amount of integration but I think I could probably waste less resources (like water) on a daily basis. As a society I think we're probably a little overly integrated and dependent just because when I think about what we would do without refrigerators, toilets, electric razors, etc. I could see a dissent into some chaos. I think waste management and conservation in general is something to be addressed as technology further advances.

Transistor Documentary Questions
What technology was used prior to transistors to amplify a signal?
Venerable Vacuum Tube
How did it change the history of communications in the US?
It impacted business, education, and culture by way of making communication available from coast to coast across the United States.
What was the metaphor that the video used to describe how this technology worked?
The metaphor used was having monkeys throw electrons into a specific target while concurrently having shutters opening and closing.
Describe the break through in the 1947 that made the transistor a reality?
The point-contact transistor occurred during issues with an initial experiment with water on a silicon plate. They ended up not using water and changing the material of the plate to geranium. Then they used a thin layer gold and upon close contact with the plate voila a transistor.
What do we learn from watching this video about group and team dynamics that we can apply to our own situation?
Comprised of experimental physicist, theoretical physicist, and team leader theoretician. All three were ambitious to a fault and their egos got in the way. It's important for our situation of group dynamics in the classroom as it's important to remember the end result and not to let your own ideas get in the way of the final vision as it can cause rifts in dynamics.
What was successful about this team?
All three were ridiculously smart and came from different fields thus allowing a greater abundance of ideas ultimately culminating in the transistor being created.
What was its downfall?
All three had giant egos and Bill Shockley specifically was overly ambitious causing a rift in the entire team.
What medic and social changes occurred as a result of the transistor?
Social changes include aiding in globalization with increased distance of communication; that's really really huge. Medical devices could also be powered more exponentially, the pacemaker comes to mind as a large medical change (used by millions of people today).

Process 1.10: Crickets
I am adding the audio to have an extra element to my project. The crickets are a project from the arduino book that I modified to work with a button activation system instead of a motion sensors activator.
Process 1.09: Laser!!
This is the laser that I am using to replace the LED strip that I could not for the life of me get to work at all. I bought this little laser from Skycraft hoping that I could find a use for it and behold. It only takes a battery to hook up to it's positive and negative connections to work. Nice and simple.
Process 1.08: Piezo Knock sensor
Here are my knock sensor connections finally working properly. I can't get them both to work with one arduino but they both work when I switch the connections out.
This is my blue LED light lighting up.
And this is my red LED lighting up.
Process 1.07: Substitutions for Final Idea
So for the finalization of this project, I have decided to make some substitutions and additions to have all of my sensor items working properly and to still represent everything I want to in order for my concept to be fully understood.
First I am replacing the LED strip simply because I am fed up with trying to make the stupid thing work. I won't be able to have the color representation of when to pass like I want to with the strip but I have found a way to represent that invisible connection between jugglers. I bought a laser at Skycraft hoping that it would come in handy if I needed to replace the strip and so it has. I will put the laser on my foot so that it will point at the person I am passing with. It is invisible and it also connects the two of us.
I am also adding an audio portion to my project. When the person I am passing with drops I will press a button that will make a small speaker make a cricket sound. This represents the boredom that experienced jugglers feel when we drop and that boredom is only pushed when we juggle with new jugglers that drop more often than us. It is not meant to be disrespectful but it is a factor of the connection between jugglers.

Process 1.06: Difficulties I've faced
The most trouble I have had has been working with the LED strip and making it work. I have tried a good number of methods to try to make this thing even turn on. Some schematics I have seen have the strip powered by something in addition to the arduino so I don't know if the strip is not turning on because it does not have enough power going to it from the arduino alone or if I have something in the wiring connected incorrectly. Either way it stumps me.
I even tried to follow the direction of someone that responded to a message I put on the forum of the adafruit site. They had a nice schematic and lead me to a link for some code to use as well. It seemed like it would work at first but the effort was to no avail. I honestly think I just can't get this thing to work.
So, I have to think about a way to accomplish the concept of the invisible connection that is developed between jugglers which is formed faster when they pass with one another.

Process 1.05: More Project changes
I've finalized my idea that I would like to use knock sensor in my hands to make the LED glow. I want to use 2 sensors; one for each hand. One will be a blue light and the other a red light. The differences in light will reflect which hand is catching a ball. Or as an alternate plan, I may use 2 of the big blue LEDs because they shine the brightest.
I want to use the small breadboards to set up the knock sensor connections on and attach them to my wrists. I have to do that because the knock sensor is not working properly when I connect the piezo to the breadboard using alligator clips to attach to wires connected to the breadboard. I think the circuit only works properly using the little blue 2 way screw terminal.
I think I need will need to use 3 separate arduinos in order to power everything and have the code properly running. As long as I have them securely taped to my person for the duration of my critique it should be ok.

Process 1.04: Soldering Alligators
I needed to make some alligator clips with wires attaching them because I bought some alligator clip heads from Radio Shack. I needed them to connect so I soldered my own wires to get them to be connected.
Process 1.03: My Project Changes
So originally I wanted to focus on the colors of the LED juggling balls that I had. i wanted to explore the understanding of RGB in the human eye and how we have the possibility to see up to 8 million colors with just a combination of these three basic colors.
Now, i am thinking about the mechanics of juggling. I want to incorporate my audience in this piece now and have them pass juggle with me. This will show how difficult it is to learn a pattern in juggling and show the audience the basic mechanic of catching and passing. This also shows the connection that jugglers have with one another even though there is no real physical connection with each other.
Sensor wise, I want to use the LED strip to be a visual of the connection that jugglers invisibly have with one another and also to help the audience member to know when to pass by showing a flow of red, red, red, green; green being the moment when the audience member should pass the their ball.
I also want to use the knock sensor set with the piezo that we made in class from the Arduino book. I want to have the sensors lay in my hand and as I catch my ball, the sensor will light an LED on the board I have attached to my chest.

1. What is an example of a semiconductor device?
Diode
2. Why is silicon used in the manufacture of semiconductors?
a silicon crystal does not have electrons that can move freely so electricity hardly passes through it
3. Discuss the difference using an example of the difference between and N-type and P-type semiconductor.
n types have no holes and negative charge while p have a a whole for valence electrons
in p types the whole becomes the carrier of electricity
4. In your own workd describe what a dioode does and the role of N and P type semiconductors.
diodes are a p type and n type semiconductor combined to make a p n junction,
they attract each other and allow current to flow in only one direction
5. What is rectification?
allowing current to flow in only one direction
6. What causes color in an LED? Give and example of what causes a particular color.
electrons and holes join near the pn junction and vanish the energy that is produced causes color in the led. wavelength controls the color,
white light - phosphor down-conversion1 is most commonly based on a blue or near-ultraviolet emitting die that is combined with a yellow-emitting phosphor,
7. What is the relationship between base current and collector current in a transistor?
electrons in connector are drawn to positive poles where they acmalate while electrons in the emitter the negative and accumulate to the base.
8. What are the advantages of a transistor over a switch?
transistors require no contact so it can be fined tuned and better controlled, less likely to fail

What is the relationship between heat and electricity. Please provide a metaphor.
Why is it warm near an incandescent light bulb?
What is a superconductor? What are they used for in real life? You may have to look this up. How could one make a metal a superconductor?
What is Ampere's Law?
magnetic fields create a circular pattern around wire if you point your right thumb in direction of current your fingers curl in direction of magnetic field is generated
If current of the same size flows in the same direction in two electric wires placed side by side, what happens?
2 magnetic fields are combined to one big magnetic field, s force of attraction causes the the two wires to attract each other
What happens if current of the same size flows in opposite directions in two electric wires placed side by side?
force of repulsion causes two magnetic waves to negate each other
elelectricity genrates heat bc the atoms that make up a substance are always vibrating. Temperature correspond to how fast atoms vibrate. Thus electrical wire is used to flow electrons bc it has little resistance making its temperature near a state of rest.
Why is it warm near an incandescent light bulb?
light emission due to thermal emission mostly ends up becoming heat
What is a superconductor? What are they used for in real life? You may have to look this up. How could one make a metal a superconductor?
superconductor is a material that has zero electrical resistance due to being below a critical temp (close to absolute zero)
They can be used in MRIs or particle accelerators. lower temperature.

Previous experience with sensors.
My previous experience with sensors is probably the same as anyone elses. I have used them unknowingly for years. I have never thought about them or their usage for more than a few minutes at any one point in time. In other words I have probably taken them for granted for all the neat things they do and the help they contribute to our daily lives. The only sensors I can remember are ones that had broken and mad me angry that things were not working because of them. Like a safety non start sensor on my motorcycle because the kickstand was down. Handy sensor, once you know you have it. Or the no start sensor on my scooter because the brake isn't compressed. It took me a while to find that one and replace it. I cant think of any other sensors off hand.
Progress of Microphone project 1
Initial project idea was to have a set of Electret microphones running a series of different lights as it picked up the sound in the room. The sounds being divided into 6 tonal ranges and each tonal range being a different color of light. I attempted a series of experiments with the microphones.
This is the purchase site page and info.
https://www.sparkfun.com/products/9964
I used this experiment code on this page to test the Electret microphone.
I was receiving fluctuating ranges and there was no sound.
I tried a different code to test the Electret and received an increasing number that went to 2400 and then fluctuated by 30 either direction with or without sound.
I began tapping the end of the microphone to see if I could get a reaction. There were changes but I couldn't tell if they were random or because it was being tapped or because the wires were being moved.
I decided that I must have damaged the microphone in the process of soldering on the end pins so I waited until the next day to get another microphone and try again.
I brought a second microphone home and soldered the ends onto it and tried the same couple of sample sketches from before with different results, however nothing that seemed to indicate that this microphone was performing its function either.
I tried 4-5 more sketches from projects around the internet that I did not save the links too and all had results of numbers fluctuating around 2400 or -550 or random in general and non seemed to react to sound. Wanting to be able to break the sound into tonal values would be nearly impossible with this microphone according to the experiments that I did with the device so I am attempting a new project.
Some of the saved sketches and sites I visited during my search for answers.
