Liu Chen said decisively: "No, now countless small companies are starting to make the idea of ​​MP3. Kang Wenbin said that as long as you use a good chip, the technical content of MP3 itself is not high, but the price cannot be reduced, the profit space is small, there is no competitiveness, and it is difficult to survive. Time is very tight and it must be launched as soon as possible."

"Are you sure?"

"Yes! Do you remember the analysis I gave you last time? In fact, I have been preparing for a long time. This is a stable opportunity to make a fortune. I will take you with me."

Lan Jun felt it sounded a bit strange. In the morning, he said he was taking others to make money, but it turned around so quickly.

"But I can't do anything except pay some money, so you can do it yourself."

Liu Chen looked at him seriously and said, "You are very important, and you need to do a lot of work."

This sentence is even happier than giving Lan Jun 10% profit. This playboy's family is not short of money. He just came out to prove himself. In addition, he was more free to spend money. He was recognized by his talent Liu Chen, and he was very excited all of a sudden.

"Okay, I'll go and register a company now. I can do anything I can, just give me instructions."

"The company name is Yinba. Since we want to do it, we must be the overlords of the digital music playback industry."

"I like this name, what else?"

"I believe you can find the relationship and register as soon as possible, and then fly to Shenzhen City immediately to purchase 128MB flash memory and sigmatel chips, with only 400,000 yuan in funds. I need you to purchase as much as possible at the lowest price as possible. I believe your ability is fine, and you can use BMW7 car keys or palmistry skills."

Lan Jun laughed, "You guy! OK, I'm good at this job. I just heard from Boy Kang that I almost hit the wall with my head. OK, I'll do it now."

"Also, the appearance of MP3 is just about finding a manufacturer to use a public mold. There is no need to open another mold, which is a waste of time and money. Remember to let them print our logo, Yinba, the pattern is a contour of the ear. I have registered the trademark in advance and applied for several related patents. As for the same sentence, the funds are only 400,000 yuan, which is not enough to find a way for yourself."

Lan Jun was about to worship Liu Chen when he looked at Liu Chen. It seemed that he was really prepared and started to do it immediately. He was considerate and didn't have to use his brain to do this work. He liked to do this work.

Liu Chen found himself excited. As expected, he didn't feel anything about money. He promised that Lan Jun would earn 600,000 yuan, which was definitely not a fool. If he did well, he could earn 3 million yuan. With this money, it would feel different. He was also a little confident in Jianghai.

You can have a happy and worry-free relationship with Zhuoling.

Lan Jun had been running away for a long time. Liu Chen admired his efficient and efficient personality. He calmed down and turned back to the laboratory.

His battlefield is here to solve technical problems.

When Kang Wenbin saw Liu Chen coming back, he smiled and said, "Ha, I thought you ran away and really dared to come back."

"As long as you help me, the ten thousand yuan fee will belong to you."

The three guys were all happy on their faces. Lan Jun was really generous and gave them money directly, but this job was not easy to do. He was so tired that he had collected information and analyzed it these days. He was still 108,000 miles away from the product.

Kang Wenbin was a little older and asked his cousin Kang Wencheng, saying, "Can he make the decision on this?"

Kang Wencheng was very shy and didn't know what to say.

Liu Chen said firmly: "I can make the decision, Wencheng and Mr. Lan went out to do business, so you will stay here in the past few days. You are mainly responsible for buying food for us."

As he said that, he paid him a few hundred yuan.

"Let's start, let's get the first demo in two and a half days."

Kang Wenbin said: "I'll agree first. In the past two and a half days, no matter whether you can do it or not, the 10,000 yuan will be all our money. You can write it down in black and white."

Liu Chen wrote a note for them. It is indeed not worth the money to help them, but this ready-made laboratory and complete equipment can be used for free, which helped a lot.

“Does there be ready-made development boards for sigmatel chips?”

"No!"

Liu Chen sat directly in front of the computer with the Protel interface open and quickly drew a chip debugging PCB. Since the layout and size were not required to be considered, it was finished in more than ten minutes.

Although it is very simple, I just sit down and draw it. It is done so quickly. When the PCB came out of the board making machine, Kang Wenbin and the two undergraduates still felt that it was a bit unreal.

Kang Wenbin said: "Don't you even look at the datasheet of STMP3410?"

Liu Chen smiled and said, "When you have seen datasheets of thousands of ICs and designed ten ICs using FPGAs, you will know that the external pins are nothing more than that."

Kang Wenbin opened his mouth and said, "There are thousands of ICs and FPGAs to make ICs." He suddenly felt that the young guy in front of him was not simple. He took his contemptuous heart and said with a board: "I'll go to the electronics market to find someone to solder the film."

Liu Chen had already sat on the side of the soldering iron and said, "No need to worry, I'll solder."

This is the IC of the cover of the SOC of the patch. It is very difficult to welding. Kang Wenbin blurted out: "You can also weld the patch?"

Haha, I have soldered the FPGA and DSP28 series, and this film has only a few feet. Liu Chen replied casually: "Soldered a few times."

"But the slant of our soldering iron is too thick. When you click it gently, the chip pin will stick. When the hot air gun blows, the chip may break. I only have two pieces, so it will be troublesome to break it. It's better to find a professional to solder it."

Liu Chen doesn't speak, and he has to speak in a slant way if he soldered a chip with such pins.

Focused and meticulous.

Holding the soldering iron in one hand, lit the rosin, a burst of white smoke rose, and the other hand was straight, carefully aligning the chip with the solder points on the PCB, and point it quickly and gently, first position the chip roughly, then finely adjust it, then touch the solder on the oblique mouth, and brush it on a row of pins very skillfully. The fine pins are soldered perfectly, and the solder on each pin is full and the arc is perfect.

Then, swish swish swish swish, and the other three sides were also cleaned.

Liu Chen picked it up and looked at the light, waved it, and handed it to Kang Wenbin, instructing: "Test the pin connection."

Kang Wenbin and the two undergraduates were shocked. This was like a martial arts master. Yun Danfeng could do it in just a few seconds.

This welding component is more like a craft, and it is not possible to be fake. Three people obey mechanically, do a good job of starting the work and test it in the past.

Liu Chen opened another computer and started writing algorithms.

A few minutes later, Kang Wenbin said: "The test is done, each pin is soldered and there is no short circuit."

There was a lot of admiration in his tone.

"Can the circuit diagram be soldered on which computer? Can the chip capacitor, resistor, and inductor be soldered?"

"I can weld this."

"Then we solder all other devices, then put them in the power supply, check the power on the chip, and then find an ordinary headphone to come over, and I will write the algorithm and transplant it in."

Several students were completely convinced and cooperated completely.
