Ye Ming picked up the electrode and looked at it carefully for a while, and then took out the spot instructions printed at the bottom of the box. After comparing them carefully, he exhaled softly and smiled at the corner of his mouth.
The reason why two pieces were sent was of course not because Tan Zhengming was attentive and offered buy one, get one free, but because one of the pieces was a scrap product and two of its pins were defective.
Because doing this for Ye Ming was essentially a favor, Tan Zhengming only charged the cost, and then sent the scrap products over so that Ye Ming could practice his skills first.
In WeChat, Tan Zhengming also made it very clear that this thing is embedded in a flexible silicone sheet. In theory, bending and deformation are no problem, but after all, the electrode itself is very fragile, so try to be more relaxed.
After reading the instructions and discovering that the other party had indeed completed the job according to his needs, Ye Ming opened WeChat and was about to send a message of thanks to Tan Zhengming, but when he thought about having to chat after sending it, he simply threw away his phone. Go aside.
"Ita, I'm starting."
"come on!"
"Well, wish me good luck - I think I should redeem it for a focus enhancement, what do you think?" Ye Ming asked in his mind, while calling out the system store.
The current exchange point stops at just over 3,600 points.
Ita thought for a few seconds, and after seemingly struggling fiercely, she made up her mind: "Okay!"
Ye Ming laughed: "Didn't you strongly advise me to save up points?"
"This is a higher priority."
"Hmm...it's really high."
…
With the blessing of the focus buff, Ye Ming entered a long-lost state of "forgetting both things and myself".
Putting on the smallest model of welding gun tip, picking up the tweezers, he began to solder the PCB board and the standard FPC interface.
Because of the need to bend, Tan Zhengming designed his electrode control chip very simply. It is just a piece of cow shit covered with an FPC (flexible circuit board - the yellow bendable one on the camera of the mobile phone). plastic sheet).
Fortunately, Tan Zhengming has made a standardized interface, and he only needs to solder the interface and plug it in.
…
Ye Ming quickly completed the interface welding, and then he soldered a small speaker on the head of the PCB, which was about the size of a headphone tuning button.
After finishing, he worked hard, connected the interface, and finally bent the silicone sheet to completely wrap the main control PCB board inside.
After it was firmly glued, Ye Ming stopped and rested for a few minutes even though he swiped "BUFF", and then started to connect the Bluetooth headset.
To be precise, he wants to use the Bluetooth module and charging module of the Bluetooth headset to realize data transmission from the electrodes to the main control chip to the Bluetooth chip to the mobile phone/laptop.
Time passed minute by minute, and when Ye Ming used glue to fix the small speaker at the front, he took a long breath.
Unconsciously, his hair had already been wet with sweat.
"It's done." He held up the earphones, which didn't look like headphones, and the brain-computer didn't look like a brain-machine gadget, and his eyes were full of uncontrollable surprise.
This thing is similar to an Arabic numeral 7. The horizontal in-ear part is densely packed with exposed electrodes, the innermost part is a small speaker, and the vertical part is the Bluetooth and battery life parts.
Because Ye Ming didn't know how the finished product would turn out, he didn't make the shell. Holding it in his hand now, it felt very piecemeal.
Ita said "hmm".
"What? Not happy?" Ye Ming lifted up his T-shirt, wiped it directly on his forehead, then picked up a cotton swab and put it in his ears.
I have a test coming soon and my earwax needs to be cleared.
"I'm very excited, but I don't know how to express it."
"This is the exact way you express yourself."
Ye Ming chuckled. He put down the cotton swab, carefully picked up the tail of the electrode, took a deep breath, and slowly inserted the electrode into his ear.
The flexible silicone quickly filled his entire ear canal.
Except that the exposed electrodes slightly irritated the ear canal at first, Ye Ming soon got used to this stimulation.
Then, Ye Ming pressed the Bluetooth switch and turned on the laptop.
After successfully connecting, he took a long breath.
"bring it on!"
"Um!"
As soon as Eta's words fell, Ye Ming felt a weak and continuous tingling in his ears.
After a moment, Etta's voice sounded: "Proofreading completed."
"Very good, how often?"
"Converted into information transmission speed, the theoretical speed is 96KB/S."
"Okay, you can go higher!" Ye Ming's eyes lit up: "I don't even feel it now."
"No, the chip can't analyze that much."
"Oh...forgot this end, okay, 96KB/S..." A smile appeared on the corner of Ye Ming's mouth: "There is no problem browsing pictures."
"Now, will you hand me the PC?"
"Okay, but wait, we need to change the Bluetooth device driver."
Ten minutes later, Ye Ming restarted the computer.
After entering the password to log in to the system, he put down his hands.
I saw the notepad page pop up on the screen without warning, and then, with a "swipe", a row of words appeared on the notepad.
"Tell me how I can quickly acquire the knowledge of each subject, whether it is through Internet feedback or your preparation for me. In addition, I think that talking to you in this way can greatly improve the efficiency of my expression."
Ye Ming looked at the row of words that jumped out almost instantly. He was stunned for a moment, and then he was very happy.
"Internet feedback is okay, but I don't think you can extract useful information from the vast sea of Internet information."
"What about the online library?"
"The online library is fine, but..."
Ye Ming said in his mind and suddenly stopped.
He could understand Ita's eagerness to learn quickly.
But... Eta can only learn through his own signal "relay station" now. It means that he must be there.
It's okay during the holidays, but what about during class?
Sleeping... is theoretically possible, but this thing is extremely fragile when inserted into the ear, and it might break if you turn over.
After a few seconds of silence, Ye Ming smiled: "Don't worry, we will make plans for the future step by step, and even if you want to study, you can't master all the knowledge, right?"
“Planning is an embedded brain-computer chip.”
"Hmm... But I think it's still a bit far away. And..." Ye Ming narrowed his eyes as he spoke: "Etta, have you ever thought about why you can talk to me in your mind, or in my consciousness. "
Ye Ming saw that the notepad paused for a few seconds before Chinese characters popped up.
"It's not a task for me to think about."
"But this is what I have been thinking about." Ye Ming smiled, but his brows gradually wrinkled: "Let's figure it out."
"you say."
"First of all, what is a system? It must be a "system" - as we know a system, it is a system - no matter what it is based on, no matter where it comes from."
"continue."
"So, how does the system, including you, communicate with me?" Ye Ming squinted and looked into the void: "Under the existing scientific theory, human consciousness is generated by the activity of neurons. , the performance is that bioelectricity is active and produces various waves at the same time.”
"You can use dimensional waves to interfere with my bioelectricity through wave-related resonance - then can I think that the communication between you and me is actually a kind of interference, but it does not involve the level of bioelectricity."
Etta: "What kind of interference is that?"
"I don't know, I suspect it's a wave." Ye Ming retracted his gaze.
"Whether the system comes and generates pictures in my mind, or you speak in my mind, it is a wave sent by the system you are in. It ignores time and space and is different from my brain waves. Intervention and communication took place.”
"And to achieve such an unreasonable exchange, I can only think that this wave can span time and space."
"Then what?"
"Then?" Ye Ming narrowed his eyes hard.
"If we can understand what technology this is, it means we can use it to transmit information."
