Back at the research bench, Chen Wangping continued to use electric current to search for sensitive resistors.
Yes, sensitive resistor, this is the name he gave to the semiconductor that had not yet been discovered.
The morning passed in a flash. Chen Wangping felt a little tired. He took out the spirit-summoning potion and the body-strengthening potion and started exercising.
"We've tested almost all the semiconductors we could find, but their reactions to spirits aren't linear. They fluctuate, sometimes strong, sometimes weak. It's not stable enough."
After absorbing the two potions, Chen Wangping could feel himself becoming stronger.
While lying in bed resting, he recalled the morning radio and suddenly remembered what Xiao Yuan and Xiao Yu said last night.
"Sulfur smell? Does this mean this spirit has been near a volcano in its past life?"
He thought about it and realized that he was too anxious to rescue people near the volcano tribe last time and did not collect some semiconductor resources carefully.
The ores and soil near the Volcano Tribe have all been baptized by volcanoes, which means that most of them are special ores ejected from underground. Both the number of elements and the retention time are better than those dug out from the mines.
The semiconductor experiments I'm currently doing always fail, so I might as well go to the volcanic tribe to find some volcanic mines to study and broaden my thinking.
The semiconductor route is definitely not as simple as just sensitive resistors. It is possible to find thermoresistors, photoresistors, and even water-sensitive resistors.
Once things stabilize later, these semiconductors will be of great use, and the more raw materials there are, the better.
Just try it!
Chen Wangping raised his hand and condensed a thunder cage to bind the spirit. After observing it for a while, he found that the spirit was now without a source of origin and its mental strength had begun to dissipate. In two days at most, it would surely collapse. He had to hurry up.
He waited for a moment, and when he saw the golden eagle come back, he grabbed it and pointed to the kitchen and said, "Where's my pot?"
The golden eagle wiped the butter from the corner of its mouth guiltily, blinked innocently, and beeped to indicate that it didn't know.
Chen Wangping smiled and said, "You don't know, right? Whose hair is this? You stole the pot too! Take me to the Volcano Tribe as soon as possible, otherwise you won't have any delicious food in the future."
Golden Eagle saw Brother Ping holding the fluff in his hand and driving Chen Wangping to the Volcano Tribe, while thinking to himself that he must pay attention to cleaning the scene next time and not leave any fluff behind.
By the way, a frying pan that has been used for a long time is really delicious.
Under pressure, the golden eagle took Chen Wangping to the vicinity of the volcano tribe in just over ten minutes.
Without the attraction of humans, the Zerg here did not gather.
They are currently munching on food in groups of three or five, looking somewhat idle.
Chen Wangping thought about it, raised his hand and gathered countless weak electric currents, which were sprinkled towards the ground. He marked all the materials that captured semiconductors, jumped to the ground and collected them.
After sensing the human breath, all the Zergs came closer and rushed towards Chen Wangping with a buzzing sound.
Chen Wangping had no time to deal with them. He instructed the golden eagle, "Stop them. I don't want to kill them, just don't disturb me."
The golden eagle took the order and flew up. Considering that Brother Ping did not want to kill him, it flapped its wings and fanned out several hurricanes, using these hurricanes to blow the latest insects that rushed over into a pile, layer by layer, like walls.
In this way, all the Zergs behind were blocked by the wall, and they couldn't jump out even if they wanted to, so they had to use themselves to block it.
Chen Wangping didn't notice this scene. He was concentrating on collecting semiconductors on the ground, which were solids of various unknown uses.
This busy work took two hours.
Chen Wangping had almost collected everything and was about to leave when he suddenly saw a red dot moving underground on the radar.
He immediately gathered his breath and observed for a while, and found that the red dot moved in a very regular pattern, appearing under his feet every five minutes.
"Is there someone underground?"
Chen Wangping frowned, and with this point as the center and fifty meters as the radius, he moved and explored several points.
But there are no such red dots at other points.
Because he was concerned about the spirits at home, he did not continue to explore. Since the red dot did not come up to attack him, he simply ignored it.
After putting away his things, Chen Wangping sat on the golden eagle and instructed, "Clean up the traces and let's go home."
"Beep beep"
The golden eagle agreed, flapped its wings, and used the coarse sand on the ground to scrape back and forth, quickly clearing away the traces.
After returning to the base.
Chen Wangping couldn't wait to continue the experiment.
The surprise is coming.
When he was experimenting with the fourth wave, he suddenly discovered that two or three types of semiconductors had a similar linear response to the approach and departure of the spirit. When the spirit approached, the resistance increased significantly, and when the spirit left, the resistance decreased rapidly.
“It really is related to the origin of sulfur!”
Chen Wangping was very surprised. He felt that the red dot he had seen before might not be that simple, but he had other things to do at hand, so he decided to wait until he finished these things before studying it.
Continuing the comparison, it would be best to find a semiconductor that is purely linear and also less sensitive to other influencing factors.
The research time passed quickly and it was evening again in a blink of an eye.
Suddenly, Chen Wangping burst into laughter. He pinched a hot translucent crystal with pliers and moved it closer and farther away from the spirit. As the distance changed, the transparency of the crystal also changed.
"Finally it worked!"
He put down the crystal, waved his fist happily, walked to the manufacturing table next to him and started drawing a blueprint. He put five crystals, five pieces of charcoal, two steel plates, a small solar panel, a battery, a buzzer and a light bulb on the manufacturing table and clicked the build button.
[Self-made drawings are being created, estimated to take half an hour]
Chen Wangping took a long breath and lay down on the bed to rest.
During the afternoon experiment, he found dozens of semiconductors that would react to spirits, but their resistance changes were not ideal and could not be used reasonably.
While trying, Chen Wangping accidentally kicked a few semiconductors near the furnace, and the heat from the furnace instantly turned the semiconductors red.
It was during dinner that he discovered the semiconductors that had fallen next to the furnace.
Looking at the red semiconductors, Chen Wangping suddenly thought that these semiconductors must also be in a high-temperature environment in the volcano.
Would that make any difference?
After testing, he found that the performance of these semiconductors had become much better, and the resistance changes of spirits were much easier to control than before.
Chen Wangping experimented for several hours according to this idea and finally found a sensitive resistor with the most suitable resistance change at 300 degrees Celsius. Although there are still some minor shortcomings, it is sufficient for now.
Now, it depends on whether the finished product is useful or not.
It's really exciting.
