My Internship in Summer 2014

During this summer, I had my first internship in Portland Oregon. This internship is an engineering-relate job. The company that I interned is called Aptic Semiconductor and the company is a  company specialized in Integrated Circuit design. I was placed in the design department working with about 10 Ph.Ds in the office.My objects were to gain exposure to the working environment in an engineering company, and at the same time I can apply the knowledge that I learned in class to the real life situation. I think I have reached my initial goals because I was able to sit in the office and worked with other colleagues. I asked my field supervisor and colleagues questions whenever I had any problems. So by now I have an idea of what an engineer life is in the office. I also realized that I have not reached the enough depth in the material I learned from school. I need to study harder in the future.


My Spring-Break plan

I am a junior in college now. Honestly, I have not done anything that interesting or crazy so far. So I am thinking that by the time I graduate from college, I have to do something that I can brag about haha. I am not an alcoholic so there is impossible to brag how many shots I can take.

But I love football, and I love Barcelona. Therefore, I am planing to go to the Real Madrid VS Barcelona game on the 22nd of March. It happened to be the last day of the spring break. When I knew this, I was like OMG I AM DOWN!!!

After this winter break, I will go and get my Visa ready. I have been looking at the ticket. It is expensive but it is ok haha. It is my dream to watch an  El Clásico.

So far, I have found 4 friends coming with me. We are planing to fly to Paris to do some shopping at Galeries Lafayette, one of the best department store in the world. Then, we will fly to Barcelona to watch the game and come back.

I am sure it will be a amazing experience. I will post pictures and details after the winter break.

The new project in Microprocessor

After we finished the binary clock project, we moved on to a new project. The name of the project is call Servo Motor control by Pulse-Width-Modulation. So basically, we have to control a servo motor to turn not just simply by giving direct order but by changing an analog input. In out case, we will use a variable resistor’s resistance as input. (Variable resistor is a device that can easily change its resistance) The variable resistor will be connected to an Analog to Digital converter, which will transform the changing analog input value to a digital signal. The digital signal will be read by the 8051 micro-controller, and the micro-controller will base on this information to give orders to motor to turn. LCD is also connected to the controller, the controller will give two pieces of information to the LCD to display. The LCD will display it duty cycle and angular speed. 1.pic

A brief thought on American to foreign countries donation

After reading the article written by Charles Kenny on finding an effective way to help countries struggling under the poverty line, I think monetary support is a big part of the aids, but helping them build infrastructure and supporting local education is even more important.

Whenever we start a campaign or a project, there is always an ultimate goal behind it, so I am wondering what is the ultimate goal for us to keep donating things we do not need to the developing countries. I believe if we are pondering this question from a basic human moral perspective, this answer can be simple: allow the people from developing countries to enjoy a better life.  However, if a kid from Zambia received a jersey from New England Patriot that costs 110 USD, do you think his life will be changed? Please let me guess his psychological reaction upon receiving the jersey.  I think he would be very excited hearing about he will get a football jersey, he would start to imagine if this jersey is from Barcelona or Real Madrid.  His anticipation would break fatally when he sees a weird and heavy jersey with some letters. The next day, the sun will rise again and he still has to struggling with lack of clean water supply while on the other side of the world is dumping water over their head for some campaign. In his country, nothing will be changed because of one sporting jersey that only Uncle Sam knows what the heck NFL is. This example is a little bit exaggerated but it implies most of our aids are not what people from developing country need!

As the article mentioned, the NFL sends clothes that they do not need to charity.  Not only can it be a good advertisement point to show the NFL is a company cares about the world but also gets tax break. Further more shipping all the cloths and toys to the areas need help, the shipping company such as UPS and FEDEX also benefit from it. Therefore donating cloths and toys will never reach the goal from the basic human moral goal we mentioned in the opening of this paragraph. As a human being, I sincerely hope that our ultimate goal is to improve everyone’s life. I hope our policymakers just chose a wrong approach. Fortunately it is not late to change it.

I believe that in order to reach our ultimate goal; we need to improve the local economy. As I said, I am not an economics major, so I cannot guarantee all my theories are 100 percent correct. As the article mentioned, if we just give cloths and food to developing countries, is not it a way to prevent the local manufacturing and local farms? I am certain that we know the concept of local, because whenever I step into whole food market, or turn on the radio shows, the word “supporting local business and local farm” is always repeatedly emerged.  Further more, we are cheering Apple for deciding to move the manufacturing lines from Foxcon back to the States! How come we are not fostering the developing countries manufacturing line? Yes, they may not have the equipment and effective protocols for manufacturing, maybe these are the vital “donations” we as a superpower in the world should be donating. Once the countries have their own factories and farms, along with support toward their education, I believe this is right way to help a country. With the cash donation, there will be more trades than ever. Trades are good things in economy it will boost the GPD growth. With the GDP climbing, the local people’s life will have dramatic changes. This method worked well, because the emerging country like China received the similar help from Soviet Union in 1950s. Soviet Union brought all equipment and techniques to China and laid a solid foundation for the future economy growth.

As the most powerful country in the world, I believe it is our duty to help people who even have trouble finding a clean water to drink rather than involving ourselves in the middle east Asia. I hope one day, Americans will leave machine guns and send experts to the world to help and improve people’s basic life. As a human being, I think a cup of clean water is more important than the word “Democracy”. Or maybe we prefer hypocrisy to anything.

Meeting with Bayern

I do believe that I have a boring life so far, because I am not a very emotional person. Alcohol or parties cannot excite me. However, there is a one thing that can actually enlivens me is football. The past summer was the best summer in my life. It was not because I had my first internship but I had chance to meet with the second best team in the world Bayern Munich. The following pictures were taken with all the players.

His name is Franck Ribéry, a french footballer who was nominated by FIFA alongside with Lionel Messi and Cristiano Ro

naldo on the three final shortlist for the 2013 FIFA Ballon d’Or.  Ballon d’Or is the most prestigious personal award for football player across the world.  The winer of this award will be regard as the best footballer in the world. 









His name is Robert Lewandowski, he is considered as one of the best striker in the world. When he was in Borussia Dortmund, he personally scored 4 goals when playing against Real Madrid.








His name is Julian Green, yea he is American!!!!! He played for the US during the World Cup. He is the youngest American player to score in the World Cup, he scored a volley in 107th minutes against Belgium in the round of 16. Plus he is only 19 years old.



I may look funny in this picture because I was in the picture with a back of a person. However, this person is my God for the past a couple of years. His name is Pep Guardiola. Before he came to the German giant, he was the coach for the best team in the world–Barcelona. He coached Barca from 2008 to 2012. Under his leadership, Barca won 14 trophies and an over 70% winning percentage.  He introduced a revolutionary style of playing, which changed the football world. He foreseen the talent of Messi, and moved Messi from an attacking winger to the “false 9”, which make Messi becomes the best player in the world. I wish I could take a “standard” picture with him but refused and told me that “No picture today, I am too ugly”.  I was a little bit disappointed but I am satisfied to have this picture.



One thing worth to be mentioned during the engineering lab

I have mentioned the stopwatch and timer project in the previous post. Therefore, I would like to talk about some interesting things happened during this project.

First of all, it was not an easy task to finish this project, because we had to first design the schematic of the whole system and then we have to solder the system, in the mean time, we have to program the chip to achieve the functionality. My lab partner and I worked closely in every step.

After we finish soldering our system, we found out that our LED display was not working. We checked our code with other group and it worked in other group’s system but ours. We had to check the signal from every single wire, but we did not find any problem. After we spent a day, we realized the main chip was broken. After we replaced the broken chip with a new chip, the problem solved.

I admit that I wanted to give up at some point, because it was very frustrating when I had no idea what was wrong with the system.  However, my lab partner and I tough it through and made the system to work.

I want to say we have to believe in ourselves, and do not give up.


About me 2

As a Chinese student studying in the US for almost 5 years, I can understand the differences between the two countries. I believe, China as an emerging country will have more opportunities to introduce its industrial products to the rest of the world. I would like to be the person, who understands the different cultures between the US and China, along with an engineering background to act as the bridge to help Chinese companies to communicate with the US.

About me

Thank you for visiting my personal website. My name is Pengzhong Robin Chen. Yes, my last name sounds foreign, I am from China. I came to the US when I was in high school. I studied at Macduffie school, which is a preparatory school in Springfield, MA.  Currently, I am junior at Trinity college majoring in Engineering. Personally, my favorite sports is soccer and golf. I have been watching soccer ever since I was a kid. My favorite team is FCBarcelona. I also enjoy playing golf during my spare time. However, as an engineering student, all the classes are very demanding. So I have to  stop playing golf during the school year. Therefore, the only time I can play golf is during the summer time. If you find any interesting things on my page, please do not hesitate to leave any comments!

Majoring in Engineering and working with other people

This is the first post on my portfolio and in this post I will discuss why I want to major in Engineering and I will also post one of my lab report to let people know what is engineering. The lab report that I will be displayed is for Semiconductor class. (I know it is sounds fancy haha) Fun facts: Every one of us is using semiconductor devices if you are reading my post! I also have a lab partner, so it helps me to know how to work with other people. Please enjoy the lab report and let me know if you do not understand anything. I would love to explain it to you.
