Door Alarm with Sew-on LEDs and the CPX

My project was a door alarm that used the accelerometer to detect door openings. My plan originally wanted to hide the processor behind felt with holes in the felt base for lights and controls. It also had the processor on the bottom and had a width far greater than the processor. The four lights were designated to the four corners of the felt. The keycard also had a similar processor design and also had a green light on top to represent if the keycard is activated.
Due to the extreme difficulty of installing the processor upsidedown, it was altered to face up while sewed on the front. As the entire processing unit became fully visible, the built-in green LED was used instead of the sew-on LED. Additionally, the processor on the alarm was moved to the top as it seemed easier to access with the keycard. The phrase “keep out” was kept. In doing so, the additional four lights had to be moved from the four corners to four points arranged in a rectangle which circumscribed the circular processor.
One of the most important things I learned was how to decrease the amount of thread and materials needed to make an item. The amount of felt used in the original design was nearly thrice as much as the finalized product. I decreased this by compacting the battery case, LEDs, and the sewed-on words. In doing so, I also limited my conductive thread usage. I would recommend decreasing the complexity of the sewing so that it would take up less time. This is mainly to improve the quality of the code, which will make the final product more immersive. It is also beneficial to begin work on the programming before the project is to be started.

My First Sewn Electronic Project

In the past few classes, I have worked on a bookmark, which was based on a very simplistic (and honestly completely inaccurately) atom. This was because I had great difficulty finding a proper design and realized that the atom looks really good.

I was most proud of the core of the atom, which looked very good with a green covering over the LED. I also really liked the design which had both metal pieces on one side, allowing the bookmark to fit into any book.

Sewing electronics were somewhat difficult as I have never done it before. The cinch stitch was particularly difficult in some parts as the metallic parts blocked the needle and also made the connection very loose. Fortunately, shallow stitches allowed for the needle to complete the cinch stitch very excellently. I would recommend future students not to pull too hard on the strings as they will easily break.

One thing I learned was how to sew on an electronic device onto the felt. This was extremely difficult to master but also very fun to do.

The Journal of Peter Francisco, a Hero of the American Revolution

Peter Francisco, also known as the Giant of Virginia or the Hercules of the Revolution, was originally called Pedro Francisco. He is supposedly from a Portuguese Aristocratic Family who had many political enemies. He was kidnapped at a young age. Not much is known about the nature of this, but some think it was arranged by his parents to protect him from their enemies. Whatever the cause was, Pedro was brought to American, where he was taken in by Judge Anthony Winston.

The American Revolution was a result of many years of slowly building hate and mutual misunderstandings. In the beginning, the British put small taxes upon the American Colonies, which have never been taxed before, due to the huge debts the government had. After many attempts, the Colonies got fed up. They formed militias. Unfortunately, the British misunderstood the American’s defensive militias and sent troops to suppress the supposed “uprising”. After much confusion and further conflict, the revolution began. In the end, the Continental Army defeated the British regulars. A new government was established, still representing the image that the American Colonies hoped the revolution would create. The British crown no longer ruled. A new democratic republic was formed in its place. Contrary to the British parliament, which was mostly controlled by the Aristocrats, the American government was formed on the basis that all had some form of control, either by protests or by voting.

The War of two Georges (Sometimes also known as the American Revolution)

The American Revolution in Plain English By Alex, George, Hanna

“Those who make peaceful revolution impossible will make violent revolution inevitable.” This phrase accurately described nearly every revolution. The American Revolution was a good example of this statement. It was also, fortunately, a revolution with fairly few deaths. The Revolution ensured North American prosperity and also began a huge wave of West Atlantic revolutions. In many of these revolutions, large amounts of people died. Unlike the American Revolution, the other kings did not let go so easily, and many bloody conflicts were fought as a consequence.

Have you ever wondered how a company like Google was created? You’d be surprised.

I recently read the book Google It, by Anna Crowley Redding. Its theme is that success does not come from being normal or being rich, but from trying things noone has ever tried, and still have the determination to continue when others mock you. For instance, the booked discussed google’s nature as a untraditional company, meaning it does not follow normative “rules”. Google was also founded under interesting condition: It was a university project. Larry and Sergey stole computers to create Google’s server due to their small amounts of money.
I would recommend the book as it is a amazingly told story about Google and changing the world. It includes much information about the people involved with Google’s creation and also provided extremely entertaining side notes of anything from Google’s new inventions to tips on swearing in Klingon.

Why should we only look at history in a single way? (An alternative view on the Boxers)

Did the Boxers deserve a bad rap?

The Boxers did not deserve a bad reputation as they were less educated and did not understand the goals of the western missionaries. The Boxers, which “was a secret society…consisting largely of people who had lost their livelihoods due to Imperialism and Natural Disasters”, were “made desperate by disastrous flood and widespread opium addiction.” They believed that these problems originated from the foreigners and, in a way, they did. However, with floods and droughts popping out whenever more foreigners arrived, the Chinese started to believe that the gods are punishing them for the Chinese Christians and the western missionaries. The Boxers, who only wanted to protect their country, decided to act and attacked a few German missionaries. However, this was only because the Germans were killing innocent Chinese citizens because their leader was afraid of the buff, strong Boxers (as explained by the tour guide). The Boxers never wanted to kill, but even the “most peaceable people” can succumb to immense pressure from other countries. A rebellion similar to the Boxer rebellion is the American Revolution. Even though America was not affected by many countries, its people were enraged by the high taxes set by the British government. Interestingly, the American Revolution indirectly caused The Boxer Rebellion by forcing the British to try and sell opium to China.

Humanism…How Humanist Am I


Currently, in humanities class, we are learning about the Renaissance. The Renaissance is an era where humans improved their way of thinking. In this project, we worked to explain the major ideas of humanism, a brainchild of many intellectuals of the Renaissance. In this infographic, I attempted to calculate how humanist I am and explain many parts of humanist belief.
I agree 4/5 towards their ideals Ad Hominem
I agree 5/5 towards their ideals De Religione, In Artis, and In Educatione.
Therefore, I am 95% humanist.

Time? How do we depict it in science fiction? Analysis of “The Sound of Thunder”

George Xu


Assignment 2


What is time, and how do we portray it? Nowadays, many science fiction authors depict stories regarding time travel. Paradoxes and changes in history are the most prominent among them. For instance, the story “The Sound of Thunder” depicts a futuristic franchise that can send people back in time to kill animals. The main character, two other hunters, and two guides were to kill a tyrannosaurus. Yet, the story is more than what it seems. It has deep philosophical ideas such as “there are consequences to your actions”, “better safe than sorry”, and “don’t overestimate yourself”. Ray Bradbury, the author of this story, depicts in this short story that even changing something of infinitesimal importance of what should not be changed can cause enormous consequences later on.

To first notice this, we could look at the beginning of the story. At the beginning of the story, the official told the main character, Eckels, that “If he [the guide, Mr. Travis] says no shooting, then no shooting.” (Bradbury 1). After that, the official warned Eckels that “If you disobey instructions, there will be a penalty…plus possible government action, on your return.” (Bradbury 1). This demonstrates the severity of the issue. One could infer that the government would interfere as they fear of consequences. Additional support would include a part of the sign: “Safaris to any year in the past” (Bradbury 1). The government might fear damage to the world as some animals might have become extinct or some other details might have been changed.

The guides are all very cautious about what happens in the past. Later, after the safari has left the present, Mr. Travis, the guide, insisted that Eckels to “Stay on the Path!” and that “If you fall off, there’s a penalty.” (Bradbury 4). When asked by Eckels to explain, Mr. Travis said that “We don’t want to change to future. We don’t belong in the past” (Bradbury 4). This also shows Travis’s caution towards their time traveling. They even sent Lesperance, another travel guide to “note the exact hour, minute, and second” (Bradbury 7) the dinosaur was killed, as to prevent drastic changes. This was made to find only the animals “with no future, that are never going to mate again.” (Bradbury 7). He then exclaimed, “Do you not see how careful we are?” (Bradbury 7).

Yet, even with all these warnings, Eckels panicked, and “He ran off the path” (Bradbury 12). Travis was enraged and threatened to kill him: “I’m warning you, Eckels, I might kill you yet. I’ve got my gun ready.” (Bradbury 13). It can be assumed that Travis is threatening him because “Who knows what he’s done to Time, to History” (Bradbury 12).

Consequences, consequences, consequences…Eckels’ sudden panic has changed the world for the worst, all because of “a butterfly, very beautiful and very dead” (Bradbury 15). All because of one butterfly, the entire language of a nation has been changed, from “Time Safari, inc. Safaris to any year in the past. You name the animal. We take you there. You shoot it” to “Tyme Sefari, inc. Sefaris tu any yeer en the past. Yu naim the animall. Wee taekyuthair. Yu shoot itt.” (Bradbury 1, 15). Additionally, rather than Keith winning the election with most people despising Deutscher (or Lyman, in the graphic novel), Deutscher was the one who won, with the official–who previously insulted Deutscher–complimenting him for the very thing the official despises in the original timeline. Eckels “heard Travis shift his rifle, click the safety catch, and raise the weapon. There was a sound of thunder.” (Bradbury 15). Travis shot someone, maybe Eckels, maybe himself. But what would happen next, what would the survivors do? Can they change history back? We might never know…



More Information:

This is my analysis of the science fiction story “The Sound of Thunder”. This short story is made by Ray Bradley, who is a greatly distinguished author and screenwriter who participated in the production of many films and an author of multiple books. Science fiction and time are closely related, and this is depicted in this short story.
