Summary of national competition experience sharing

As an old hand who has organized three or four batches of junior students to participate in e-sports competitions, I would like to tell you some things beyond the rules. Based on my own personal experience, I want to let you know that even if some of the rules of e-sports competitions are clearly written in black and white, you don’t need to take them too seriously, so as not to suffer losses:

First, in 2009, when we were making broadband DC amplifiers, there was a need to make AC-DC power supplies (about 10-15 points, I can’t remember which one). One group was running out of time, so they took off the shell of a switching power supply bought on the market and took it to the site. They passed the test smoothly. The other parts were not bad either, and they won the national award (if it weren’t for the power supply, I think they would have lost the national award);

Secondly, there were two interesting rule-breaking things in the previous session (4 years ago). One was the use of four "DC vortex fans (the competition question specified that only computer cooling fans or their enhanced versions were allowed)" to control the laser pen at the swing end to draw circles on the ground. Because the younger students were working on quadcopter control, on the first day the question came out we twisted the four wings of the quadcopter (aluminum alloy) downwards 90°, and then adjusted the algorithm. All the basic parts and the extra points were completely exceeded; (for example, the first 15 seconds to swing to the corresponding angle requirement, the quadcopter can achieve it in 3 or 3 seconds, a crushing effect). Because the effect was so good, we could get close to 100% for something we made in one day. We were worried about violating the rules of the competition, so we went back and used the SB snail fan for three days, barely achieving 60 points. Then when we got to the scene, we found that Jiaotong University and Fudan University were all using quadcopter motors. Damn, they instantly crushed our snail fan (specified by the competition) in terms of scores. The organizing committee turned a blind eye, hiahia, damn! Then we heard that some quadcopters bought ready-made flight controllers and made some minor adjustments, and still got very high scores. So from that year on, all of us began to doubt the authority and enforcement of the competition officials in setting the rules! Then, in the last year, the opportunity came.

In the last session, although the opportunity came, the students were not strong enough, but this gave me a chance to test the bottom line of the competition organizing committee (because these weak students were not familiar with me, and they would not blame me if they got into trouble, as long as I didn't have any pressure in my heart). The topic was visible light communication and positioning, and then I directly asked them to find someone who was learning Android, and used a Raspberry Pi to install a camera disguised as a visible light receiver placed at the bottom that could be moved, and then the positioning was very accurate and not affected by ambient light; at the competition site, the judges were very puzzled, your opportunity had no communication capabilities, but the positioning was very accurate! And the anti-interference (ambient light) ability was very strong, and they were very puzzled, and then they fooled the SB judges in this way, and let a team with nothing won a provincial second prize, Hiahia;

So through the above cases of nearly ten years, I want to tell you that only SBs completely abide by the rules of e-sports competitions. The rules of e-sports competitions are partially meant to be broken, and you just need to fool the judges on the spot, and fooling the judges is really easy! Therefore, there are definitely some who want to win by strength, but they are very few. It is more about testing your ability to find loopholes!

I typed this quickly, so there are some typos, such as "found a junior who studies Android", "almost no communication skills", etc. But I have said so much, and I can summarize it in one sentence: You should exploit the rules and loopholes of the e-sports competition if you can, and you will suffer if you don't! The judges on site are very easy to fool, and if one of them is from your school, it will be even easier!

Suddenly I feel that saying this has too much negative energy, so I will add a few hypocritical sentences: the process is important, the process is important. I also have unlucky junior classmates who are very capable but only got the second prize in the province (second prize in the municipality). However, after graduation, their job opportunities and salaries are much better than those who took advantage of loopholes and won national awards (they definitely have the ability, but they are definitely a far cry from those very capable junior classmates). Society is different from electronic competitions. It does not look at your ability to take advantage of loopholes for a while, but at your ability to study and improve through persistent efforts. So even those juniors who did not want to take advantage of loopholes or did not take advantage of loopholes in this electronic competition, don't feel completely hit (we embedded people have the natural ability to withstand blows, otherwise how can we fill the countless pits ahead?), you can take this as the starting point for your accumulation and progress, and after such dedicated efforts, you will find that the whole world is different!

/*First of all, I am not sure whether it should be written here, and secondly, my feelings may not be helpful*/ Preparation: 1. If you are not sure whether there will be questions this year, do not buy the corresponding chips; 2. General modules can be prepared first, such as MCU modules, power modules, etc.; 3. Find suitable teammates who can contribute; 4. General skills should be mastered, such as the use of single-chip microcomputers, the drawing of circuit diagrams, and related theoretical processes: Discuss the questions first after getting them, and form a reasonable plan. The specific ways to form the plan vary; the division of labor should be allocated to the parts that each person is good at; buy the modules needed in the process if you can, and try not to make them yourself without chips; it is not recommended to stay up all night, you can use the Da Vinci sleep method; the report can be written on the last night, or someone can write it specifically. Summary: If the three of you work hard, you will definitely be able to finish it.
