Arduino Studio Time Week 4

Arduino Code/Studio- Week 4

For the Arduino Studio time we followed a digram to allow the code to 
function properly. The light readings would lower or raise depending on the amount of light. The HOT wire was connected to the 3.3v and the GRND wire was connected to the 5V. The sensory wire was green and connected to the Arduino as well. A 10k resistor was used and we were shown a code that would affect the light sensitivity. 

Project One Idea

Project One Idea- EMF Detector

For Project One I thought of creating an EMF Arduino Detector. The purpose of this device would be to detect electromagnetic frequency levels in the area. Stronger energy currents would result in higher readings on the device. EMF would be detected through one or more antennae attached the device. The readings would be shown on an LCD  screen in a digital form or the LEDs would light up. The device would be black, white, blue or red in which I attached the designs below. 

  • Mini On/Off Power Button/Push Button Switch -$ 0.95
  • 1x 101-100 ohm Square Soft Touch T18 Potentiometer-Blue- $ 0.50
  • 1x Large Enclosed Piezo Element w/Wires -$ 0.95
  • 11x 100ohm resistors-$0.10
  • 1x solid wire (antennae)- $0.10
  • Various Stranded Wires (different colors) -$0.30
  • Diffused Red and Green Indicator LED 18mm Round- $1.50 
  • (Other Option LED)- LED Assortment, 5mm, 20each Red, Green, Yellow, Blue & White- $ 2.95

Example of Circuited Board, Sketches and Completed Examples

Other Information

  • The detector would require baseline readings under the same conditions in order to prove accurate. 
  • EMF detectors are highly sensitive to motion.
  • Those who are hypersensitive to EMF may display whole host of physical, mental and emotional symptoms that could be confused with paranormal activity. 
  • EMF can also cause sleep disturbances which also relates to paranormal activity.

Toaster Article

Toaster Article-Maker Movement 

The toaster resulted in the book "Toaster like Monstrosities". The author of this article states that nobody was able to manufacture a pencil in 1958. They also state that a regular toaster was cheaper than Thomas's. Thomas had spent 250 times as much money and traveled thousands of miles to build his own. Toasting bread however wasn't the purpose of the toaster. The purpose was rather to challenge if one could manufacture an object from scratch using hand-made materials. The author states Thomas found it nearly impossible to manufacture a toaster by scratch.

Toaster from Scratch Video- Maker Movement

Thomas Thwaites attempted to craft a toaster from scratch from collected materials. He quotes Doulas Adams in " Left to his own devices he couldn't build a toaster. He could just about make a sandwich." Thomas quotes this because Douglas realizes that without human society he could only make a sandwich. Thomas wanted to challenge this theory. Thomas started this challenge by purchasing an electrical toaster and taking it apart. Inside he found 400 bits and realized he couldn't work with all the materials. Instead he chose 5 materials which were steel, mica, plastic, copper and nickel. Thomas first sought out a professor who taught him how to craft steel and went to an iron mine to mine his own ore. He found that steel was actually crease limestone produced by sea creatures 500 million years ago. Thomas was told this information by Ray would was a professional in mining. Thomas brought a suitcase full of ore back to his town and went to the History of Science Library. There he found history about metalology and smelting. Thomas first used a trashcan as a smelting space but then switched to an industrial microwave. The next material Thomas searched for was copper. He brought back copper minerals in water jugs. He then went to Scotland to mine Mica ands used plant starches for oils for plastic. He tried contacting BP first but they declined his plastic request. Snails ate the potato starch for the plastic so the casing had small holes. The overall result was interesting but would have been better if Thomas was able to include insulated wires so that it functioned properly. However, I find it impressive that the toaster was able to function for a few seconds. Thomas was smart in making a mold for the toaster out of a tree but I wish that the actual object was sturdier. 

Week 4 Reflection

This week I learned about Arduino Boards and how to make them function with code. I learned that sensory wires are usually green and that a LDR is used rather than an LED. PWM  means pulse width modulation and allows you to program RGB ( Red, Blue, Green). A 10k resistor is needed aswell. The GRND & HOT Wires and connected at specific points on the Arduino Board. 

I am currently struggling with deciding on an idea for project One. Both my ideas require work and I am lacking in the creative process in order to decide on a project.

Maker Movement Article Discussion

Maker Movement Article

Amy Hurst conducts research to solve the Maker-Movement problem of non-accessible tools due to high-costs and technological barriers. She develops tools almost anyone can use and works at the Prototyping and Design Lab. Amy engages individuals with needs in science, tech, engineering and math (STEM). Hurst realized that people with disabilities and impairments couldn't access current DIY tools. She also realized that people would rather repair/customize what they owned rather than create new things. This led her to develop new tools/platforms under "Making for all". The tools developed range from VizTouch to GripFab. VizTouch allows teachers to print 3-D math questions that are tactile for visually-impaired students. GribFab allows disabled individuals to print custom hand grips. The National Science Foundation (NSF) supports Hurst and those similar to her. NSF focuses on the curious, creative and self-driven crowd that engages in making. The role of NSF started in laboratories across the nation such as The University of Texas, Massachusetts institute of Technology and University of Rochester. NSF has committed more than $200 million to manufacturing research and other activities. Today, NASA,NIST and the Dept of Energy are also involved in 3-D printing and manufacturing. Due to the research being federally supported, major tools in DIY activities are possible. Some of these tools include CNC routers, computer aided design and Scratch Programming Lang. Inside Hurst's makerspace, those with intellectual disabilities are able to learn to design/print objects using technological design tools. President Obama hosted the "National Week of Making" in order to lift up creators and builders across the country. The first National Maker Faire was organized on June 12th-13th. NSF helped open the CITRIS Invention Lab in 2012 by providing funds to plan and design the Lab. CITRIS is intended to allow students to change ideas into realities. Skintallates which is an electronic temp tattoo was made in the CITRUS Lab and won "Maker of Merit" at the National Maker's Faire. Ben Shapiro and Brian Gravel from Tuff's University created a makerspace which transformed into Nedlam's Workshop and was funded by NSF. The workshop is largely used by Haitian females. Nedlam's workshop encourages ethnicity and equality. Researchers Erica Halverson and Kimberly Sheridan found that makerspaces share themes. These themes are multidisciplinary fuels engagement and innovation, makerspaces have a marked diversity of learning arrangements and learning is for the making. However,  they also observed there is tension in making between open -ended and structured activities inside makerspaces. Research is currently in action to develop a solution to this. Overall the NSF and other government agencies supporting research/development and education that will create a technological break-through.

Maker Movement Video Discussion

Maker Movement Video Discussion 

Leah Buechley enjoys working in the Lab and calls it one of the best jobs on Earth. She created the program High-Low-Tech in order to help everyone fall in love with technology and construction instead of consumption. Leah explains that the program takes everyone seriously and brings creative experience to those who are alienated from technology in particular. The program achieves this by planting technology in unexpected places. Involving paint and paper with technology is one example of this process. Leah's student had created a pop-up book infused with LEDs. Leah believes that this enriches expressivity of design and creation. She builds tools and kits that help people become connected with technology. The kit consists of non-toxic water based conductive paint and a set of traditional electronic modules. The kit works by glueing modules to paper and using the paint to sketch out ideas. Leah states that working with paper and paint in technology changes it in interesting/profound ways. She also states that people are able to manipulate paper in more ways than wires. This can influence how we think in building technology. She created another kit called the Lily-Pad Arduino which engages new people in technology.  The kit engages new people through allowing people to sew electronics onto their clothing/daily fashion. The kit consists of a sewable computer and assortment of switches, sensors, motors, lights and conductive electrical thread. These assortments are sewn to clothing with the thread and are claimed to be washable, wearable and flexible. Some of the projects manufactured with the kit include a dress that detects CO2 levels in the atmosphere, biking jacket that uses LEDS as turn signals and illuminates the rider, Embroidery piece and a handbag that records/play backs knitting patterns. Leah believes that technology needs to expand in different creative directions than just robots and soldering. She concludes that the more people involved, the greater the change. 

Week 3 Discussion

Week 3 Overview

I wasn't able to attend Wednesday's lecture so I didn't learn much this week. However, I do have challenges I am facing in this course. I faced the challenge of learning to solder without burning off component pieces and faced difficulty in finalizing my project 1 idea. Currently I am worried about how my project will turn-out due to missing the coding tutorial in class and lacking experience. I am also concerned about the cost of the materials and if the code and end project will function properly.

Project 1

Project 1 IDEA - Arduino Car with Wireless Controller

For Project One I am going to work without a partner. However, I may change my mind if I find the project too difficult. During my research I found an article about a robotic car. I would enjoy creating a small robotic car for my project because I feel that it would be simple and a fun learning experience. However I am going to need a lot of materials. The picture below is my inspiration for my project while serving as a model. 

Arduino Robot Car Project
Project 1 Research/Documentation 

Research One -Home Automation System
This project was posted by user, DIY_Bloke on Instructables. Bloke had rewired his Home Automation System to function through Bluetooth when he's away from home. He transferred the entire Arduino based system to ESP8266 in order to do so. He is able to switch on laps, fans, etc. 

      He used the enhanced RemoteSwitch Library for his 433 MHz Library. His also used ESP8226-01 which is considered the most simple. He then uses a GP102 to connect the signal pin of the MHz transmitter and feed everything with a 3.3 volt. 

Research Two-Streaming Sensor Box
This project was developed by Chloe. She created an autonomous way to monitor a location's temperature/humidity, light activity ( On/Off) and motion within area. 

           First she sets up the Arduino Yun which has an onboard Wifi module that makes establishing internet connection easy and turns your information into a personal home dashboard that's accessible on laptop or mobile device. Yun runs from an SD card which she plugs into her SD adapter and then her computer. Chloe then downloads OpenWRT and zips the file to to her SD card and ejects it. She places the card into the Yin's micro SD slot and plugs the Yun into her computer using a USB cord. She then connects to the Arduino Yun-90 wifi created by the Yun. She then logs into and configures the Wifi to a wireless network. She then sets up Yun with Arduino IDE and installs the DHT-Sensor-Library. Chloe then adds sensors and wires the circuits. She   made sure that the 3.3V power and ground are provided for the sensors. She then connects a male-male tie line from the 3.3V power to one row on the breadboard and one from GND to the breadboard. She connects the light sensor or SIG to A0 using a female-male tie line. The temperature/humidity sensor is connected to Digital Pin 2, and the motion sensor is connected to Digital Pin 3. She then connects  VCC and GND on each sensor to the 3.3V Power and GND rows on the breadboard. She combines all the sensors together and the result is a functioning sensor box! 

Research Three- Arduino Radar (Sonar)
Dan developed an Arduino Radar that detects objects in front of it and maps them on the PC screen using a processing IDE. The project includes a ultrasonic sensor, small servo motor and Arduino board. The range of radar can be adjusted to up to 4 meters with 180 degrees rotation. 

Dan first made a cardboard stand to connect the ultrasonic sensor to the servo motor. He then connected the jumper wires and secured the motor to the Arduino board using elastic bands. Lastly, Dan made a code and uploaded it to the Arduino Board which allows the motor to move. 

Circuit Board 2 LEDS

Activity ( 2 LEDS)

I faced trial and error  completing this activity. However, in the end I knew how to correctly light more than one LED and calculate the resistor needed. I started off with two green LEDs but recreated the activity with two blue ones. 

                                                                        Step 1

For step one I gathered the materials needed such as a circuit board or breadboard, ground wire, stranded wire, wire strippers, wire cutters, soldering iron, soldering wire, 9V battery, small cut wires, resistor and two Green LEDs. 

Step 2

  For step two I soldered the black wire to the negative side and the red wire to the positive section to create flow in the right direction. 

Step 3

For step three I soldered the wires to the bread/circuit board, making sure to solder the points together to create flow throughout the wires. I then added the resistor to prevent the LEDs from burning out when they were lit. 

                                                                          Step 4

For the fourth step I soldered the LEDS to the board, making sure to connect the opposite ends of the legs ( positive to negative and vice versa) for the LEDs to establish correct flow. I soldered the negative leg or cathode to the resistor because the flow was flowing from the negative wire at the start.  However, the negative leg of one LED was soldered off in the process resulting in the lighting of only one LED. 

Step 5

I recreated the circuit and connected the battery. Success!

Physical Computing Project 2

Donut Security System

                The Donut Security System was developed by Daimberston who is experienced in technology. The purpose of this invention is to monitor a donut. The pressure sensors detect the weight of the donut on the plate and when the donut is stolen, sirens will sound to ward off thief. The code could be calibrated to protect other treats such as cupcakes and pie. Supplies used for this creation include components and connectors such as a USB power source for Arduino, Bread Board, Piezo Element, Pressure Sensor, Red and Green LEDs and wires( used to lengthen pressure sensor and LEDs. Daimberston used tools such as soldering irons, wire cutters, scissors/exacto knife and a computer (for code). The software used is Arduino IDE. Other supplies used include small paper plates, Tubberware, Tape, Donut and Decorations. Daimberston documents his construction process in his article. His first step was to use the soldering iron to lengthen wires on pressure sensor and LEDs. The finished components were to be 8-10 inches long. The last step of the first part of progress is to complete breadboard/Arduino. The next step is to code. Daimberston then uploads the code to Arduino and tests the pressure sensor by squeezing it. He cuts a hole in the plate and slips the pressure sensor through it. He then places another plate on top of the sensor and places donut on top of plate to check reading. He then attaches the 9V battery and cuts two holes in the plate to put LED through. He places the set-up in the Tubberware container and cuts two holes through it to allow pressure sensor and LED through. Lastly he places plates on top of the lid and places the donut on the plate.

Maker Article Post

Maker Article Discussion 

                 Mark Hatch who is CEO of Techshop discusses various principles in "Maker Movement Manifesto" These principles are Make, Share, Give, Learn, Tool-Up, Play, Participate, Support and Change. He introduces us to the topic of Make by quoting that " The point of making is to "take manifesto, apply changes and make it your own." Mark discusses how making is fundamental to being human and that physical making is more personally fulfilling than virtual making. He believes this because of the tangibility aspect of physically made objects such as touch, smell and even taste. Mark then goes onto say that God is a maker meaning we were made to create. He states that nothing can replace philosophers, religious scholars or personal experience. I agree with this because because your experiences are your own and your mind as-well. The DIY home improvement industry is described as being worth over $700 billion the U.S. The most valuable area of this industry is perpetual remodelers or those that have the funds to pay other people to create for them, but don't. Mark emphasizes maker space which is a center of workspace where similar-minded people come together to create. Some examples of these creators are white-collard types such as designers and medicine practitioners. Mark finishes the maker section with his personal experience making a wonky vase which is now a memento of his childhood. It still travels with him. The next principle Mark discusses is Share. He introduces us to Share through the quote "You cannot make and not share. A feeling of wholeness is achieved by sharing." Mark believes that we are wired to show what we create and provides us with an example. This example is how young professionals tend to admire what they create and are eager to present it in stores. Mark draws importance to the idea that the size of impact isn't significant but that the impact made the item tangible. Mark states that this is powerfully satisfying and that the best attribute of a well-run market space is sharing of skills / knowledge. This is true in the idea that knowledge and skills are needed to create. 
The next principle in "Maker Movement Manifesto" is Give. Mark quotes that "Giving someone something you made is similar to giving a piece of yourself". He believes this creates cherishing. He states that it is more valuable to create gifts for others rather than buying them from shelves. I agree with this in the aspect that creating gifts provides more value because you put yourself into it. An example of a company who gives in the article is Embrace Global. Embrace Global used Techshop for development work in developing blankets for infants with thermoregulation problems in developing countries. Jane Chen developed the concept of creating an affordable blanket known as the Embrace Portable infant warmer which resembled a small sleeping bag. The portions of the technology for this project were provided by Tech shop members. General Electric joined to distribute the blanket and 100,000 lives of infants were saved in the next five years. I personally believe this is a developmental breakthrough and that giving results in revolutionary changes. Learn is the next principle discussed in the article. The principle is quoted by " you must learn to make". This is true in one must learn and brainstorm in order to create.  Mark believes making brings out natural interest in learning. He states that Project -based learning adapts to some learning styles better than others. Mark believes this is because the process feels more natural and that principle is found through observation. He ends this section by emphasizing that schools deny children important life skills by focusing on those that will attend college and ignoring those who aren't. This point frustrates me because it is true that schools pay more attention to those seeking degrees. Mark discusses Tool-Up as a principle that  you must have the right tools to create the project at hand. He draws attention to the fact that tools are becoming cheaper, more powerful and easier to use. I agree with this that tools are becoming more powerful because of technology. Mark believes Makerspace is beneficial to affording tools but that they should provide certain tools to meet community needs. Some examples of these tools include Laser Cutters, CNC milling machines and a 3D scanner. Staff should also be provided to teach classes at makerspace. Mark describes the Play principle as being playful with your creations will result in excitement and overall enjoyment. He believes that productive environments feature lots of laughter. This is true as you should work in an environment that you enjoy. Mark brings up his son making a hovercraft with a leaf blower in the article and that this building is a form of play. The principle of Participate is introduced by Mark suggesting to join the maker movement. Working with other people is solitude and that getting young people excited about science is the main drive for the movement. Mark explains the support principle as the movement needs emotional, intellectual, financial, political and institutional support. That this research requires approvals and funding from third parties and receipts from foundations and the government. Mark states that we can help allocate new funding to set up open access labs and fabrication studios. The last principle discussed in the article is Change. Mark encourages us to embrace change by joining the maker movement, participating locally and opening up our horizons to overall help us become us. I believe this is an important message in helping creators globally come together and manufacture future masterpieces.
