First of all, let me make it clear that I am not here to brag about myself. I want to show you how I have spent the past four years, so that you can avoid taking detours. University is really a good place to learn.
I was admitted to Harbin Engineering University in 2002, and now it is my last semester in undergraduate studies. When I first entered the school, I knew nothing about electronics. I was more interested in business, and I applied for business management as my first choice, but I was not admitted and was transferred to the School of Information and Communication. Now it seems pretty good. When I first entered university, I thought it would be great to be a class monitor or to hold an official position in the student union, so I joined the school student union and the department student union since my freshman year, and always ran for class cadres and so on. Later, I got what I wanted and held a lot of positions. I didn’t know what to learn in my freshman year, and I had classes every day. I didn’t dare to skip classes at that time, and my life was very ordinary, but also I felt very fulfilled, probably because I was still excited after leaving high school. A year passed like this, and then I was in my sophomore year. The last semester was the same as my freshman year. There was nothing special. I always played basketball and football. One day in the second semester of my sophomore year, I woke up. I remembered my dreams, my ideals, and what my future would be like. My major is electronic information, so I must achieve something in this area. Two years have passed, and I am studying electronics. I don’t even know what resistors are. What kind of electronics major is this? I found a classmate in my dormitory and told him that we should participate in the school’s May Fourth Cup Electronic Design Competition together. My classmate agreed, and we randomly found one from an electronics magazine. I forgot what phone call I made to the police, but I copied down all the components mentioned above. The two of us went to the electronics market to buy components. It was our first time buying electronic components and we didn't know anything. A resistor was charged 10 cents, and we ended up buying a bunch of resistors, capacitors and transistors for a total of 60 or 70 yuan. We came back and prepared to solder according to other people's drawings, but we didn't do it well. Later, I asked the teacher who taught me the basics of circuits, and told him that I wanted to learn something, could he help me think about what to make? My teacher was a very nice person, and he told us directly that we could come to his lab, and that he was leading a few students to do their graduation projects, so he asked us to learn something. We moved our computers into the lab I went to his laboratory, and then worked with a female senior classmate on a laser communication device. It happened to be the May Fourth Electronic Design Competition at our school, so we took the things made by others to participate in the competition, and we won the second prize. That was because others did a good job, and we didn't know anything at that time. After the May Fourth Cup was over, my roommate moved his computer back to the dormitory from the laboratory, and my computer has been there until now. Later, my teacher gave me the key to the laboratory. Around mid-May, I met another teacher (he is now my good friend). He told me that as a student of our department, if I learned microcontrollers, C language, and DSP, then I would have a bright future. The future will definitely be good, I believed him, and I started to learn single-chip microcomputers. At that time, I was the only one in the laboratory, learning hardware, and I was the only undergraduate student. Other graduate students were surfing the Internet every day to play cards, chess, chat, and watch movies. This is also what I have seen the more advanced people do in recent years. At that time, I couldn't tell which end of the polarity capacitor was the positive pole and which end was the negative pole. I took a capacitor and asked about seven or eight master's students and doctoral students in the laboratory, but none of them knew. Of course, I was shocked. Could this be a high-level student who studied electronics for four years as an undergraduate and several years as a graduate student? We really can't blame the current graduates for having difficulty finding jobs. That's because you really don't have The reason why others need you. I wanted to learn microcontrollers at that time, but I had no hardware and no one around me knew how to do it. So I went online to look for information and saw that there were microcontroller development boards for sale online. The prices were quite expensive at that time, but I still made up my mind to buy one for more than 300 yuan. After it was sent back, I started to practice. I had read a few books before, but I found that reading alone had no effect. When I was doing experiments, I would look up the books so that I could remember them clearly. From then on, I arrived at the laboratory at 8 o'clock every morning. From then on, I often skipped classes and stayed in the laboratory all day until 10 o'clock in the evening when the old man who watched the building told me to leave. I was fiddling with microcontrollers every day. At that time, no one taught me. I did it all by myself. I figured it out by myself. At that time, I was learning assembly language. I had also learned C language before, but I found that I couldn't use it at all, which was the same as not learning it at all. About a month later, when summer vacation was about to start, I made my first single-chip microcomputer product, an electronic clock. Some people say that if you use a single-chip microcomputer to make an electronic clock, you have basically mastered 80% of it. I think this sentence makes sense. The electronic clock has a very high degree of comprehensiveness in programming. During the vacation, I signed up for the 2004 Heilongjiang Province College Student Electronic Design Competition. At that time, the topic we chose was wireless data communication. The instructor asked us to use FPGA, which also required VC programming and C++ language. I began to work hard. I learned FPGA in these two months, but I didn't know VC yet. There was a classmate in our team who learned VC very well. He was from the School of Science and he learned VC all by himself. (He now works in a game company in Beijing.) We were satisfied with the result of the competition. We won the first prize in Heilongjiang Province. This was my second award. Then I found that I must learn C language. A comprehensive talent cannot only do hardware and not understand software. Those who only do hardware are workers. Since the beginning of the first semester of my junior year, I have not been to the classroom to attend a class. Until now, I have completely given up studying theoretical courses, because I found that the theoretical courses and the last semester were only for the final exam. Even if you get 100 points, you still don’t know anything. In fact, it only takes one day to prepare for the final exam. (Later, I found that one day was too much, so I changed it to two hours for each subject.) I was satisfied with just 70 points. Since my junior year, I have always actively signed up for any electronic design competitions in school, just to find opportunities for training. This year, I have not I have never played ball in the street for a day. I get up in the morning, wash my face, brush my teeth, take books to the laboratory, I write programs, solder circuits, and do various hardware exercises in the laboratory during the day, and come back to study my theoretical courses at night, analog electronics, digital electronics, high frequency, and go to bed at about two o'clock every night, combining practice with theory. I found how important theoretical knowledge is in college, and we didn't realize it before, just for the final exam, so it loses its meaning, that's because we learned in the wrong direction. If a person's foundation in analog circuits, digital circuits, and high-frequency electronics is not good, then he can't design any good circuits. It's very good to look at the theoretical knowledge in the book while doing practice. This went on for a year, and during this period I won some national and school awards. The senior year came, and life didn't change much, it was still the same as the junior year. The classmate who participated in the May Fourth Cup with me is now busy preparing for the postgraduate entrance examination and reviewing every day (he did very well in the postgraduate entrance examination and was admitted to Harbin Institute of Technology). I don't want to take the postgraduate entrance examination, I plan to find a job. When it was almost October, another teacher of mine who was very good to me told me that a certain electronics company in Beijing recruits two or three students from our school every year and requires hands-on ability. He recommended me to go, saying that the treatment was not bad, and I agreed. Their company came to the school for an interview on October 3rd, and our teacher recommended three people. Because that company always came to our teacher to ask for people, they took them away after seeing them. I was preparing for the interview. On October 2nd, the school posted a notice that I was exempted from the test and recommended to study as a graduate student in our school. I was very happy. There is no tuition fee for recommended graduate students, and there is no need to take an exam. Our school has a system that students with special skills in certain areas and who have won higher-level national awards can be recommended to study as a graduate student without taking the test. My comprehensive score averaged more than 70 points, which was enough. Thank you for the school's system. In the second semester of my junior year, I basically studied C language, VC, and C++. In the first semester of my senior year, I basically participated in the 2005 China Aerial Robot Competition. Our school defeated many famous universities such as Tsinghua University and won the national runner-up. I learned a lot in this competition. During the winter break of my senior year, I started to plan to design my own products. I searched online for information, drew circuit boards, and began to prepare to develop a practical single-chip microcomputer learning board for beginners who wanted to learn single-chip microcomputers. It came out half a month later. I spent a week debugging all the routines and started advertising and selling them. Now it seems that the sales are not bad, and the profit is enough for me to eat. Then I designed the second version and now I am planning to launch it on the market. The routines have been written. I originally wanted to study economics, but I didn’t have the opportunity. Now I have professional knowledge, and it should be more suitable to do business.
My undergraduate studies are about to end. I have spent four years like this. Sometimes I think about it and realize that I may have lost a lot of things, such as happiness, but what I have gained is priceless. I have not been home for four years. Sometimes I can't even remember what my parents look like. Because of my dream and my revenge, I have overcome everything that could stop me. I have made full use of every minute and every second of every day and I feel very fulfilled. To sum up, as long as you have ideas that are better than others, you have the desire to excel, you can make up your mind to do something, and you have the perseverance to stick to it, as long as you make progress every day, two years later you and most of your classmates will be at completely different levels. It is no exaggeration to say that you may not be able to communicate and there will be barriers when discussing professional knowledge. College is the most precious time for each of us. You have paid the price of four years, and you must gain something for it. I advise younger students not to be addicted to online games or love. People should have higher pursuits. You have to lay the foundation for your future life. The outside world is cruel. You are very lucky to be alive. Cherish it!
