Hour of Code

     For the hour of code, I worked with my grandma, friend, and in class. I went on the hour of code website and did coding with minecraft with my grandma and friend. In class I worked on making an Arduino playing jingle bells with flashing LEDs. The amount of code written was around 15 pages. On the Arduino Project, I worked with Will Langas.

Makerspace Orientation

    Over the past few days we learned how to use some tools in the makerspace. One of them is a tablesaw. We learned how to make different cuts and how to use it properly and safely. We also became familiar with general rules of the makerspace. Appropriate clothing must be worn. No loose items like jewelry and headphones. A person has to be getting enough sleep so that he/she is always alert when using a dangerous tool.

Summary Statistics

    We learned in class how to calculate the mean, mode, and median of a data set. We also learned how to calculate standard deviation and make histograms. This will be useful when we start making and measuring different parts once we start building. We learned some math symbols that we need to know in order to calculate standard deviation.

Maker Movie Reflection

    The modern population is using a lot of products. All those things had to be designed and invented. That's what makers are for. Makers manufacture, design, innovate, invent, program, research, and build. A lot of new inventions have something to do with technology. There are always many jobs available associated with the STEM fields. People are tired of not seeing what they want in stores. They are inspired to make something themselves. Makerspaces help people begin making what they want to do. The people can use the tools to do absolutely anything. Underwater robots and satellites were created with something as cheap as an Arduino. People can raise money with a website called kickstarter producing what they invented. I plan on making something with an Arduino as soon as I get one.

Linear Dimensions

     Linear dimensions help people measure the right amount of material they need. Labeling different dimensions has multiple rules that one needs to follow. Dimensions are usually labeled in a multiview sketch and have to not repeat. If the units aren't labeled we can assume that it's in inches.

Dial Calipers

      In class today we learned how to use dial calipers. They are way more precise than rulers because they can measure precisely to a thousandth of an inch. They have multiple measurements which they can do like length and hole depth. Dial calipers will helps us make exact measurements when we are working on projects.

Measurement and Unit Conversions

   There are 2 common measurement systems: the metric system and the U.S. system. In order for scientists and engineers from different parts of the world to communicate, people have to be able to convert measurements. We have recently been measuring different objects using both systems and converting measurements from one system to another. Although both systems have the same time units, the measurements for distance and volume are completely different. Thankfully, we are able to use conversion factors to convert any measurement from any system into another system of measurements.

2.4 Multiview Sketching

      For the multiview sketches, we sketched the top, front, and right of each object. We had an isometric sketch to look at and we were supposed to sketch it as well. Multiview sketching shows more detail than other sketches and that is why it's used by professionals.

2.2 Perspective Sketching

     Perspective sketching gives a realistic 3D view of an object. There can be 1, 2, and 3 point sketches. A vanishing point is a place where all lines will meet in a sketch. Perspective drawing takes up some time because you have to draw extra line and then erase them or make them bolder. I enjoyed learning this new concept.

Activity 2.1 Isometric Sketching

    Isometric Sketching shows the object's height, width, and depth. That makes isometric sketching 3D sketching. In class we learned how to make isometric sketches as well as sketch isometric circles. Sketching the circles involved several steps. My isometric circles turned out to be pretty bad since I cannot draw a straight line. With a little practice in sketching and shading we are all going to be able to do good isometric sketches.

Twitter Accounts

        I think that our Twitter accounts are going to be useful because we will be able to expand our knowledge. We can follow accounts that interest us on Twitter. From those accounts we will have access to websites and articles that will enhance our learning. Multiple sources of learning will be more beneficial to us than learning from one source.

Initial Maker Faire Ideas

Today we all looked at possible categories our Maker Faire projects could be about. We all wrote our initials next to the categories that interested us. I think that I will probably be interested in making something associated with programming. I think I want to use an Arduino Board or a Raspberry Pi to program something useful. One idea that our group has is to make glasses with a screen inside so that you can watch movies. The frame for the glasses will be printed out using the 3D printer. For that we will need the following items: a screen, lenses, glasses, and a Raspberry Pi. I will be working on this project with Joshua Goldshteyn. It is possible that if we finish the project early, we will start making something else with an Arduino.

Instant Challenge Paper Bridge


A paper bridge that we built

The goal of this activity was to build a long paper bridge under a limited amount of time. I enjoyed doing this activity, but it was very frustrating when the bridge collapses. The bridge ended up collapsing at the very end. The length was only 6 inches, but we were able to have better results before it collapsed.

The Evolution of Air Conditioners Will Blow Your Mind
by Nick Solonko

     The extreme heat in some regions of earth really seem to bother people. Sweat is pouring down their temples. They are unable to concentrate, relax, and do their job. Something similar happened President James Garfield after he was shot. Wounded, President Garfield stayed at the White House where it was extremely hot in 1881. It was July, the middle of summer. He had people submerge cloth into ice cold water and then blow air through it. Although that did drop the temperature by about 20 degrees Fahrenheit at the White House, more than 500,000 tons of ice were used to keep him cool over the course of only 2 months. Later, he died. A normal electric fan was invented a year after that. In 1882, Schuyler Skaats Wheeler invented the electric fan in Los Angeles. It was later sold at Crocker & Curtis electric motor company. The rotors of the fan were made out of brass and while they spun they directed the airflow in a certain direction. These fans were used for cooling and ventilation. The motors had silk or cotton insulation which made the motors 80% larger than they are today. Later, the insulation was made of Polyimide coating. In the 1890's fans started having fan cages around them to protect the rotors. A few decades later, brass cages got replaced by steel because brass was needed to make bullets for WW1. Even though fans provide ventilation, it was proven that they don't cool the room. They actually make it warmer because of the heat produced by the motor. It still feels cooler because the air is traveling at higher speeds inside a space. In 1902, Willis Carrier invented the first modern air conditioning system. Ammonia was used to coolant and it was highly toxic. His air conditioner could significantly lower the humidity and that made the room feel cooler. A large % of humidity makes the temperature seem really hot. For example, a person dies within 6 hours if the temperature is 100 degrees and the humidity is 100%. If the humidity is lower, a person will have no trouble living with that high of a temperature. Even 29 years after the invention, the average air conditioner cost between $10,000 and $50,000. In modern currency it is between $120,000 and $600,000. Only the wealthiest of all people were able to obtain one. Current air conditioners are smaller, more efficient, and have more options. They are usually made of steel and plastic to reduce weight. Electric fans are still used today and also keep on evolving. Both mechanical and aeronautical engineers work on evolving air conditioners. Today, air conditioners are almost in any household, office, and store. People in most countries of the world use air conditioners regularly and can't imagine a life without them.

Product Improvement Reflection

This activity helped us learn how to work together to come up with creative ideas. Our group took a normal tape roll in order to create something more unique, useful, and advance. Although a product like this would cost too much for normal population to afford, we had a lot of fun creating these original ideas and deciding whether to use each or not. The results turned out to be unusual. Please see the sketch below.
This is the sketch of the improved tape



Concept Sketches Reflection

In class we began doing concept sketches on objects with as much detail as possible. Our goal was to shade them in and make them look 3D. I wasn't quite able to master that. I liked it though because I thought that I would do much worse. I liked it and decided to sketch one extra item. It took me a long time to sketch the glue bottle because of the amount of details in it. If I had a chance to do this over again, I would pay more attention to the way the light falls onto an object. Overall, I think I was successful and I'm looking forward to doing more in the future.
