Abandoned candy boxes, building blocks, LED lights, lithium batteries, mobile phone software, these seemingly irrelevant things, in the hands of Xu Jiayin of Xiyuan Xincun Primary School, combined into an intelligent colorful electric fan that can be controlled by Bluetooth of mobile phones. Xiao Jiayin is just curious and fun, and doesn't want to win the grand prize of Anhui Youth Science and Technology Innovation Competition.
Fan is very clever.
When the reporter came to Xiyuan Xincun Primary School, 1 1 year-old Xu Jiayin was fiddling with his invention in the school laboratory. The reporter saw that this small fan with a height of about 30 cm is based on an iron candy box, and a row of LED lights are installed on the beam of plastic building blocks. Open the phone software and four buttons will be displayed on the screen. "These four buttons control the fan switch and the LED light switch respectively." Xiao Jiayin gave a live demonstration. Under his operation, the blades of the small fan rotate rapidly, and the four LED lights light up sparkly. "You can receive instructions within five meters, which is very flexible. Not only can you carry it with you, but you can also set a password for special purposes. "
Without an external power supply, where does the fan's electricity come from? Xiao Jiayin opened the candy box, which also contained two lithium batteries and a Bluetooth receiving module. "It only took 50 yuan to make this fan." Xiao Jiayin said that the raw materials are basically waste, and the lithium battery can be recharged and recycled, which is very environmentally friendly.
He is very happy to win the prize.
Referring to the original intention of making this fan, Xiao Jiayin came to the fore. He said that last summer vacation, I went to play with my cousin who was in high school. There are five or six people living in the crowded dormitory, and each person uses a big fan. "At that time, I wondered if I could make a fan for my own use, without occupying limited space, and I could adjust the control myself." The idea stayed in Xiao Jiayin's mind for a long time, and later he told his mother about it. With the strong support of his mother, he began to become a fan. To this end, he searched a lot of information and found that the mobile phone software can be installed, but how the fan can receive the signal better really made him spend a lot of thoughts. For more than two months, Xiao Jiayin experimented repeatedly and finally succeeded.
The reporter saw that all parts of the electric fan were welded and assembled firmly, and all of them were completed by Xiao Jiayin alone. "It was originally for fun, but I didn't expect to win the third prize in this year's provincial youth science and technology innovation competition." Xiao Jiayin said that he was very surprised and happy to get this award.
Looking for inspiration in comic books
"The child's way of thinking is funny. Sometimes some ideas are different from others, and he likes to use his brain. " Tutor Liang's evaluation of Xiao Jiayin. In the school's robot lab, Mr. Liang showed many robots assembled by Xiao Jiayin, some of which can identify obstacles and some can make various body movements. "Just like Lego mindstorms, I am preparing to assemble a group of robots, in which the leader robot can work with a group of small robots." Speaking of which, Xu Jiayin looked very excited.
In the class, Xu Jiayin's academic performance is also excellent. Besides hands-on operation, Xu Jiayin's biggest hobby is reading comic books. Although he is only 1 1 years old, he has read hundreds of cartoons. "I like reading science fiction comics best and can give me a lot of creative ideas." Xiao Jiayin said
