Without money, I dare not do anything; I need to find a way to make money first!
Otherwise, if we can't even afford the patent fees for the research results, how can we compete with others?
Back in the simple office, I began designing a 27MHz wireless transmission for Li Wengang.
Early 27MHz technology had poor anti-interference capabilities and a very short transmission distance of only two meters.
Although there is interference, it is not easy for crosstalk to occur.
Later, as the technology matured, it was mostly used in home wireless audio systems and wireless microphones.
Most of these are used in children's wireless remote control cars, toy yachts, and other toys.
Xing Baohua wanted to help Li Wengang create a later, enhanced version with a longer transmission distance, reaching up to about 120 meters, and without signal interruption. Its only drawback was slightly weaker anti-interference capabilities, but in this era, this was negligible unless the other side used a jammer.
To achieve a wireless transmission range of 120 meters, a repeater is needed in the middle, which is equivalent to building a bridge for the signal.
Once I had an idea, I started drawing diagrams.
Xing Baohua also wanted to get a wireless microphone, which would require a voice module and a digital transmission module.
A microcontroller chip can handle it.
Anyway, it was just an experiment. If it was successful in audio equipment, we could upgrade our own audio equipment to a "plus" model.
After all, the gimmick of wireless transmission can fetch a high price.
Who would want to do the wiring?
There will always be people who find it convenient to buy it.
You only know if it's a rip-off after you try it. You'll only realize the advantages of wired connections when you understand that wireless transmission only plays audio and has little to do with sound quality. But the product has already been sold?
At that time, there was no wireless transmission for playback sources, so what could we do? We had to buy a walkie-talkie and talk to whoever we were talking to?
Then you have to buy one get one free, and include an adapter or something, so that the playback source can send out wireless transmissions.
Xing Baohua handled the chip issue himself. As for the other small components on the motherboard, Niu Jishan took care of them.
He stayed at the factory until evening, then went to the machinery factory to pick up Su Ya. He told Su Ya that he was going to the provincial capital the day after tomorrow and asked her to prepare.
Despite not wanting Su Ya to go with him, he still softened his heart.
Go see what he's been up to.
Maybe they won't check up on you anymore.
As a result, Su Ya told him that Hu Jiangyan had taken leave and wouldn't be coming to work at the factory for a while.
If she leaves, there will be no one to take over the shift.
Well, that's good news.
After dropping Su Ya off at home, I still need to go to Zou Wenjuan's place to get the sheet music! Don't be fooled by the bite I got last night; it was just an unconscious, impulsive act.
Thinking back to the food we ate at Zou's house last night, it was surprisingly meager. I didn't tell them beforehand that I should at least buy some cooked food this time.
I rode my bike to the factory's supply and marketing cooperative first, and bought two pounds of pig's head meat, braised beef, and canned luncheon meat on credit. After thinking about it, I also bought a big watermelon.
Bring two packs of cigarettes and two bottles of Wuhe Daqu liquor to the Zou family.
When Zou's father opened the door, he saw Xing Baohua carrying a bunch of things, and this time his voice wasn't as loud as before.
After Xing Baohua called out "Uncle," Zou's father said, "Come in."
As it turned out, there was no food on the table. Xing Baohua guessed that he had arrived too late and hadn't even gotten a meal.
After placing the things on the table, he asked, "Where's Wenjuan?"
“In the inner room.” After saying that, Mr. Zou sighed softly, and finally said, “Xiao Xing! I know you are both young, but it’s best not to go too far in some things.”
Xing Baohua was completely confused by what he said and didn't know how to respond, so he could only nod to acknowledge it.
In Zou's father's eyes, this meant he had agreed.
Xing Baohua went to the small boudoir.
Zou Wenjuan looked unwell; she was probably still angry from last night.
Hearing Xing Baohua knock on the door, he turned around and saw this guy standing at the door, saying, "Why are you here again!"
“Come sing with me! You have no idea how tight my schedule is. I’m going to the provincial capital to coach the orchestra these next couple of days,” Xing Baohua said.
"You, directing? You've gone to Siberia for all your work. I'm afraid you'll take the orchestra to the Arctic," Zou Wenjuan said with a disdainful tone.
"It was indeed guidance. They would transcribe the tunes I hummed and practice playing them according to the sheet music they had copied," Xing Baohua said.
"Is it the one on Wenhua West Road?"
"I think there's only one orchestra in the provincial capital, right?" Xing Baohua said.
I was still angry with Xing Baohua, but as soon as we started talking about the band, I forgot all about it.
Just as Zou Wenjuan was about to get angry, Xing Baohua, seeing that things were not going well, quickly changed the subject and said, "I ordered an electric musical instrument. Don't you know how to play the guitar? You can play the electric guitar yourself."
"Electric guitar? I've never played it before, and I don't know how!" Zou Wenjuan said.
"It should be about the same. I remember that electric guitars also have six strings, just like guitars. You'll figure it out if you experiment a bit," Xing Baohua said, while also thinking to himself: playing and singing by himself can save on the cost of one person.
"Which song are you going to listen to tonight?" Zou Wenjuan asked.
"Do as you please"
This song was very difficult to sing, and Xing Baohua was not in the right state of mind. Zou Wenjuan believed that Xing Baohua did it on purpose.
It wasn't intentional. The rhythm was too fast, and Xing Baohua could only hum along from memory. It's normal for her to go off-key. If she felt she was off-key, she would just sing it again.
This made it difficult for Zou Wenjuan to listen to.
The song didn't even have a rough draft until midnight.
Xing Baohua thought to himself, "Old Li is really amazing! He finished a piece of music in less than two hours, and he even did the arrangement."
It was late, so I didn't disturb Zou Wenjuan's rest.
When he left, Zou's father finally had a smile on his face, which probably meant that Xing Baohua had taken his words to heart.
Even Zou's father was worried that his daughter would bully Xing Baohua, so he wanted Xing Baohua to carry a small umbrella for self-defense, because safety is quite important.
