"Master, the tea is ready~" While she was fiddling with it, Sanmao called her from outside.
Li Xin had asked Sanmao to make some black tea before. When he heard the news, he hurried out with the radio, ready to drink tea and listen to the radio for a while.
Li Xin drank a sip of tea comfortably, only to find that the radio he had just found was broken and could not be used at all!
Sanmao was accompanying her, also staring at the radio curiously. Li Xin put down her teacup and fiddled with the radio.
After tinkering with it for a long time, there was still no sound from the radio.
Forget it, instead of spending time repairing it, I might as well just modify it so that I can still play with it and it won’t be wasted.
"What should I change it to?" Li Xin muttered.
Sanmao, who had been watching her curiously, reached out and pressed the button of the radio.
Li Xin looked at Sanmao, then looked at the radio.
Got it!
Make a small metal detector for fun. In this day and age, you might actually be able to find treasures!
Li Xin happily picked up the radio, stopped drinking tea, and turned around to enter the space.
The research institute was well-equipped with items. Li Xin first looked around for materials and only entered her laboratory after finding everything.
First make an induction coil, take a circle of about ten centimeters in diameter and wrap enameled wire around the circular object to use as a probe.
The circuit board can be used directly from the radio, with a little modification, and it is quite simple to lay out the wiring.
The power of the resistor was not enough, so Li Xin found a few more and connected them in series on the circuit board. This way, the electrode would be stronger and the magnetic field would be larger.
For the speaker, just use the one removed from the radio; one will do.
