The time has come to three o'clock in the afternoon.
If I hadn't drunk a bowl of ginger soup during lunch and hadn't left the restaurant.
They think they might have caught a cold by now.
But for Class 9, it is still worth it.
When they successfully drew the circuit, the sense of accomplishment was even stronger than before, even comparable to the sense of accomplishment from shipbuilding.
Although the difficulty of the two is incomparable, the process is also incomparable.
But rubbing the circuit board by hand proved one thing to them.
Now, not only can they seamlessly combine mathematics and physics, but they can also easily combine physics and chemistry.
After this experience, they could clearly feel that their abilities had made a qualitative leap.
Especially in the calculation of various currents and resistances.
They didn't know how many difficulties they had encountered, and they didn't even have an accurate idea of how much current should flow in each place.
If it weren't for the instruction manual provided by Teacher Ren, there would be no detailed description of this aspect.
They are afraid that they are still struggling.
There is no way, the necessary conditions are really not sufficient.
Fortunately, their teacher had obviously taken this into consideration.
This allows them to draw the circuit board in the same way as doing a problem.
But it is different from doing exercises because it involves practical problems. After making a mistake, they can always verify it through calculations and know clearly where they went wrong.
After such a long time, some physical and chemical formulas that I originally felt unfamiliar with have been thoroughly consolidated.
This makes them feel wonderful.
I used to really hate my teacher's way of changing the soup but not the medicine.
In the end, the sense of accomplishment still made them laugh out loud.
"How shameless...we..." Wang Bo laughed at himself silently.
The people around him rolled their eyes: "What are you talking about? We are just fulfilling our duty as students, how can you talk like that?!"
"So, our ultimate duty is to play games?" Xia Yue smiled secretly with her hands covering her mouth.
Class 9 rolled their eyes again.
This couple is hopeless!
"Alright, alright, stop talking. We have just finished drawing the circuit diagram, and we need to print it on the copper plate and etch it." Ah Wei said at the right time: "After etching, we still need to install and debug. How can it be that simple~"
After he finished speaking, Awei took the drawn circuit diagram, made some backups, then stuck it on the copper plate and soaked it in hydrochloric acid.
After about ten minutes, the entire copper plate turned green.
Awei picked it out with a clip and wiped it dry.
Then the paper and ink were cleaned up, and the yellow lines were still there below.
After seeing these complete routes, everyone in Class 9 breathed a sigh of relief.
The most critical step has been completed.
"Okay, let's have a steady hand for the rest of the work, and let's solder the resistor on!"
"Who among you can do it?"
After a moment, Zheng Chen raised his hand and took the job.
As a contestant who can draw in the waves, Class 9 really couldn't find a more suitable candidate.
However, not long after getting started, Zheng Chen began to regret it.
It’s not that electric welding is difficult. As long as you have a steady hand and are a little careful, there won’t be any problems.
The main reason is that my classmates are too talkative.
"Hey, hey, you're going the wrong way! A little to the left!"
"Isn't your solder joint a bit too big? It looks asymmetrical!"
"No, no, your craftsmanship is too rough. It doesn't reflect the meticulousness of our Class Nine."
"Brother, don't tell anyone you're from Class 9 when you go out. We can't afford to lose face like that~"
Words like these keep appearing in Zheng Chen's work.
To put it nicely, the students feel involved.
But what is the reality?
Isn't it just that you can talk without back pain while standing? !
Finally, Zheng Chen raised his head, holding the welding gun, and looked around at the students with a cold look, and said something that was very shocking:
"If you can do it, come on!"
"What the hell~"
In the end, in the face of Zheng Chen's presentation of facts and reasoning, everyone in Class 9 rationally backed down.
After about another hour, the circuit board was finally soldered and the cables were connected.
Although a few pieces were used for practice during this period, the results were still good.
The moment when everyone connected this controller that they had worked so hard to make to PS5 via Bluetooth and started using it.
There were exclamations again on the deck.
Then came the sound of scrambling.
Although this handle still lacks many parts, it does not have any gravity sensing or vibration feedback.
But at least it’s playable!
I have spent so much effort just for this moment!
On the side, Zhang Ting, who had been watching Class 9, decided to give Class 9 a day off.
Let them experience the joy of success and let their bodies recover at the same time.
There's no rush for that day anyway.
After making this decision, Zhang Ting also joined in the scramble for the handle.
And immediately formed a superior pressure and took the lead.
......
And in the captain's room.
Listening to the shouts coming from the deck, Ren Yan smiled calmly.
I feel more or less relieved in my heart.
After such a long time, I was finally able to learn most of the subjects in Class 9.
The only thing left is foreign languages.
Thinking of this, Ren Yan decided to cover herself with the quilt and fall asleep to the sounds of Class Nine playing...
