When I was a child, my favorite program was "I am an inventor" on Children's Channel. Inventors from all over the country showed their talents on this stage, recommended their whimsy to the judges, and some even obtained invention patents.
I thought: What if I were a little inventor? Curiosity prompted me to take down a radio at home to see what made it sound. It turned out to be those two pot-shaped speakers, one put together.
It consists of a magnet and a small coil. When the power is on, the horn will make a sound. After dismantling this, I dismantled my own remote control racing car, trying to study why the racing car can run around by pressing the remote control button. As a result, the shell is opened.
After the child, there is a modest circuit board. A small wooden board can make the car run back and forth, and it can also be deformed and overturned. The design is really exquisite and amazing! Naive, I also want to take apart the circuit board, but that's right.
There is a big gap on the side, which seems to be enchanted and firmly fixed in … When I tried to install the radio and remote control car again, I was immediately startled, and the parts were torn apart by me and mixed together. I
Afraid of being beaten, I had to pretend from memory, either backwards or wrongly. It took a lot of effort to finally install all the components. Who knows, turn on the remote control car switch, the car won't go, it's just a mess.
Call. The radio is broken, too. I was really curious and did a bad thing. Finally, with grandpa's help, it was repaired, saving me a beating and scolding.
As I grew older, I gradually learned a little about electrical appliances. Whenever I have time, I always read and study hard. I don't know how many times I have dismantled the toys at home, even the old mobile phone that my father eliminated. I have looked at it for a long time over and over again.
That day, I was looking for something at home. I saw an old mobile phone when I opened the drawer. After cleaning, I saw that it was not bad. I just can't turn it on. Curious, I wanted to open it again, so I took out my toolbox and used a screwdriver.
I removed the phone case. Look at this. Found a broken line at the interface inside. I immediately picked up the ferrochrome, soldered the wires, fully charged the battery and tried to turn it on. The mobile phone is actually quite good. I really thought.
I am very satisfied with my actions. Dad came over, smiled and praised me and said, "Ren Jie, you are great! It is a child with strong hands-on ability. " Hearing this, my heart is as sweet as honey.
This is me, a child who is curious about the world. I will continue to explore endless mysteries in the ocean of science.
