On the Hudson River, on the window seat of a café.

Two graduate students were talking to these two first-year college students.

"The one you are holding in your hand is the most basic power supply circuit diagram, and the basic functions of the general power supply are all in it, including filtering, protection, voltage transformation, heat dissipation, etc., but this solution cannot directly produce products, because now the computer power supply outside has different design specifications.

For example, AT standard, Baby-AT, but because of the progress of science and technology and the development of computer hardware, Intel will also launch a new generation of design specifications this year, and many scientific research institutions have obtained the standard specifications provided by Intel, which is called ATX.

I have two AT and ATX power design solutions here, but ......"

Jack's eloquence may be better than George's, and in this little negotiation, all the technical introductions are explained by Jack.

Su Jingzhen listened to Jack's words, pursed his lips and thought for a while, the two graduate students were a little nervous, because they were poor, really poor, so Michelle called and said that they wanted them to study a power supply scheme, and they copied one copy of the school's computer power supply overnight, and then deduced and designed two new solutions according to what they learned.

Columbia University, it sounds very majestic, but when it comes to Columbia's electrical department, many people may not have the impression that Columbia's business school is doing well, and the schools of journalism, law, arts and sciences, and engineering and applied sciences are all ranked among the top schools and departments in the United States.

But the electrical department has been pressed by Stanford and other departments to hold its head up, so many years have not produced good results, no grades, there are fewer people to study, can come to the Ivy League either rich, or high IQ, who will go to the department with no future?

No one comes to study, which makes it more difficult to get grades, so in a vicious circle, the electrical department of Columbia University is not enough compared with other departments, and it is difficult to apply for things like scholarships.

When they heard that a big customer wanted to buy a gadget like a power supply, the two graduate students were moved, because the computer power supply is not too high science and technology to speak of, and they can play casually.

To put it mildly, as long as you have a certain amount of electrical knowledge, a junior high school student can assemble a power supply in the garage of your own home, and all the components can be bought in the market without any difficulties.

And now the big wrongdoer in front of him will buy his own design plan? It has become the most concerned issue for the two graduate students, and the concern is chaotic, so they are a little nervous.

"That's it, this thing, we have to find someone to verify it, if the solution in it can satisfy us, then the follow-up design will be done by you, we can sign an agreement, do you think this will work?" Michelle saw Su Jingzhen silent, not sure if he was satisfied, so she stood up to play a round.

"Actually, I have learned some knowledge of computer power supply before, it actually has no technical content, because the design specification is taken out by Intel, everyone just does it, so the quality of a power supply is reflected there? It's not about the design, but about the selection and coordination of the components, I don't know if you're interested, work for me for a while, of course, it's part-time. ”

After Michelle's words were finished, Su Jingzhen added that what he said was not all right, and a smart circuit designer is still very important, which can avoid conflicts between many components and save costs.

"Long-term?" George said the first thing he said when he came to the café today.

"In the short term, based on the time when this power supply is designed." For the power supply, in fact, Su Jingzhen doesn't pay too much attention to it, the reason has been said above, he has specifications, and the general circuit diagram has been set, just like the graphics cards of later generations, although there are different brands, but they are all public versions.

Unless your manufacturer has such technical strength to research, and the research product is indeed better than others, the cost is lower than others, and the price is higher than others, otherwise most manufacturers have no incentive to redesign a new set of circuit diagrams.

But do you say that Su Jingzhen doesn't pay attention to it, it's not, after all, the power supply can be used for a long time, and its quality can directly cause whether the computer can be powered on, in case the quality is not good, then the reputation will be finished, so there is a contradiction in this.

In Su Jingzhen's original idea, the power supply will be patented together with the chassis, and the lower power supply, envelope, and back line are all fresh things, which can apply for some unique shape patents with the chassis, forming a unique patent trap.

So, should the power supply be redesigned? Su Jingzhen's answer in his heart is yes, but do you want to put a lot of money into it? That's not necessarily, but now that two ready-made scientific research dogs have come to the door, Su Jingzhen refuses to let them go, so he will ask them to work part-time for a while.

"Yes, but we still need to go to class, so we don't have too much time, and we can't leave school for a long time." Jack looked at his companion and saw that George had no opinion, so he directly agreed to Su Jingzhen's solicitation, but he also put forward corresponding conditions.

"That's no problem, I try my best to make the work in the form of piecework, and every time you complete the work, you will get paid accordingly, so that you don't have to go to work regularly, which is the biggest difficulty." Su Jingzhen also has some experience in management and can immediately propose solutions.

"So, let's celebrate?" Michelle saw that the two sides had negotiated, and raised her hand to call the waiter over, wanting to order food.

"Hey, don't order alcohol, around the school, someone will check it at any time." Su Jingzhen glanced at the big fat girl and reminded him.

"You're under legal age?" The two graduate students on the opposite side were curious, after talking for so long, they didn't dare to ask Michelle and Su Jingzhen's age, and now when they hear this, they don't seem to be twenty-one years old?

"Uh...... We are students at the Stern School of Business. Su Jingzhen did not directly explain how old he is, there are actually many social taboos in the United States, such as age is one of them, especially for women.

"Don't drink, let's have coffee, we can still eat a little heart, it's time for afternoon tea." Michelle will be very obedient, Su Jingzhen said that you are not allowed to order wine, so you will not drink.

But when I said to eat, what did this bastard boy mean by looking at me?

Michelle sensitively discovered Su Jingzhen's small action, which was not too obvious, and was sad and indignant...... (To be continued.) )
