Otaku Engineer in Great Tang Dynasty Chapter 1645: Thermal power!

　　,!

　　 "Blue bird, have you tested this thing, how far can the maximum communication distance reach~?"

　　 Qiquge Workshop, the scientific research base of Assassin Project, tried this cross-age first-generation telephone several times back and forth. Li Zexuan called Li Tai over and asked with joy.

　　 He really did not expect that the assassin project would progress so quickly. At first he thought that Datang wanted to build a "high-end product" such as a telephone, and it would have to wait until next year at the earliest!

　　"Mountain long, this I’ve tested by Mr. Mochui before, and the sound can’t be heard at the farthest distance of one mile! At first we thought it was due to the loss of electrical energy during transmission, but we tried to increase Large power supply voltage, it will still be like this! Uh, two other test products were burned out because of the high voltage~!"

　　 Speaking at the end, Li Tai scratched and looked embarrassed.

　　 Li Zexuan was speechless after hearing the words: "Of course you can’t blindly increase the voltage in this case. Some components in the phone have a certain withstand voltage. If you blindly boost the voltage without any basis, you will surely let it inside. Caused irreversible damage!"

　　 Li Tai was a little embarrassed and said: "The leader taught me! It's the green bird Menglang~!"

　　 It didn’t take long for him to get in touch with electricity. It’s not easy to build a telephone based on the ideas and ideas provided by Li Zexuan. As for the other details, how can he think so thoroughly~?

　　 Li Zexuan shook his head, and said: "Qingque, you first undertook a big project like the killer project. It is not easy to find a solution when you encounter problems. Engineering is a subject that constantly explores the truth through experiments. It’s not terrible to fail. What’s terrible is to shrink back because of the fear of failure!"

　　 Speaking of this, Li Zexuan turned his head, and then said: "But I still hope you can pay attention to safety during the experiment! You have rashly increased the voltage before, burning things out, causing the components to be high-voltage breakdown Leakage is a big deal! Before you make a decision, you must think carefully and anticipate the consequences in advance!"

　　 This is not Li Zexuan’s alarmist talk. The first generation of telephones made by Li Tai is completely a simple circuit composed of some components connected by wires. It is very rough. After all, this era does not have the advanced integrated circuits of modern times. Technology, even Li Zexuan, the raw material for making circuit boards, is now hard to get together!

　　 In addition, there are a lot of capacitors, diodes and transistors in the circuit of the telephone. Once something is broken down due to excessive voltage, it is completely possible to cause leakage. Then the person holding the telephone is likely to be I was electrocuted directly!

　　 Listening to Li Zexuan’s words of solemnity, Li Tai's face also became serious. He solemnly arched his hands and said: "Remember the teachings of the chieftain!"

　　 Li Zexuan nodded with satisfaction. The little fat man in front of him is Li Er’s baby bump. You can arrange for him to do scientific research, but you must not let this little fat man finish his life, otherwise Li Er will definitely not give him Good fruit!

　　 So the safety education for Li Tai must be kept up!

　　"But the mountain is long, why the transmission distance of this telephone is only one mile~? This problem has bothered me and Mr. Mochui for a long time~!"

　　 After a moment, Li Tai returned to the subject and asked.
