But they have no idea of ​​the suffering in Xing Baohua's heart.

The real challenge now is designing a best-selling export product.

Back at the workbench, I sat down and started pulling at my hair with both hands. You said you wanted to suddenly produce something, but you couldn't think of anything for the moment.

He can't handle large machinery, so why is the DMD factory manager bullying someone who works with microelectronics?

Just thinking about it made me anxious. I asked Xu Shuai for a cigarette, walked to the door, sat on a recliner, and looked at the road with few cars and people.

Suddenly, he saw an old man selling melons at the bus stop not far away. His wheelbarrow was piled high with two baskets of melons. After weighing the melons for the customers, he drew on the ground to calculate the amount of money.

Electronic scale? Calculator?

This is threatening the Bureau of Metrology's job, but who cares? Let's do it, it's not difficult.

Calculators don't have high requirements for chips, and there are plenty of domestically produced microcontrollers available at lower prices. Furthermore, the programming isn't complex, and the components are readily available.

It's nothing more than making some changes to the appearance and feel. These days, electronic calculators are still quite expensive, and they're considered tech products. The key is that they contain chips.

A Japanese calculator manufacturer placed an order with Intel, inadvertently creating a behemoth. Intel's groundbreaking 4004 chip was specifically designed for calculators.

In terms of quality control, price, appearance, and labor costs, we can compete with the Japanese.

Let's do it!

With this in mind, Xing Baohua quickly went back to his room to write the project plan and design the product appearance.

Xu Shuai and Liu Quan were already used to Xing Baohua's writing and drawing. They even thought he was publishing another article.

To Xing Baohua's surprise, there was someone else who was also working hard to study things.

When Zhao Shanhai saw Director Li looking for Xing Baohua, he was already disheartened, knowing that he couldn't recruit Xing Baohua.

He was unwilling to accept things continuing like this. After years of hard work, he had finally risen to a leadership position, only to have his resignation wipe him out. How could he accept that?

As Xing Baohua suggested, they found two small speakers in the factory's inventory of parts, and the factory also had soldering irons and other equipment, so they decided to take it upon themselves to figure it out.

The speaker wires were soldered on, but something seemed to be missing. So I rode my bicycle home and took the only medium-sized radio in the house to the factory to have it disassembled.

After some research and effort, the speaker finally started working. The only problem was that the radio didn't have an external jack, so I had to use speaker wire to connect it to the speaker inside the radio in parallel.

The sound of the loudspeaker gave him hope.

So I tried several speakers, both large and small.

As it turned out, he did find some troublesome problems.
