This week's circuit city video leaderboard is changing, there are all kinds of projects that have recently been booming, there is a cool LED matrix production process, there is an irregular model project plan, and the world's survival warning system project plan, and animation points 5G The impact and harm, more exaggerated to create a simple board small batch production line ...
Which video is the most user-like? Please come together with Xiaobian to uncover the suspense, the mystery is in the weekly circuit city video leaderboard TOP10.

TOP10: "Fire Light" dismantling: Analyze the reduction circuit solution from schematic
When I first saw this "fire lamp" at the local shop, I think this is a bit awkward.
I originally expected that it will use the board from the flame lamp, and may even just a flashing LED. But the flame effect system it uses is identical to the flame effect system used by the full-size electric fireplace.

TOP5: 5G: Danger? An animation understands the convenience, risks and challenges brought by 5G
5G getting closer to us. At the end of last year, the Ministry of Industry and Information Technology issued a 5G system low-band test frequency using the Ministry of Industry and Information Technology. According to the timetable of the three operators, this year, 5G equipment will begin trial commercial.
If you often pay attention to the push of CCTV news, I believe that you have had a certain understanding of "5G". However, 5G is a new technique after all, many netizens said after reading the Popula, I also want to know when I can use the 5G device, and more secrets behind 5G technology. Today, Xiaobian has prepared a "scientific class" for you, I believe you will find a variety of questions in this video.
A new generation of mobile phones and smartphones seem to be launched every year and provides faster speeds and connections for everyone. But what is the danger of this connection? This video analysis 5G, let you know the future of cellular services, the techniques and equipment behind them, and all the information involved.

TOP4: Jetson Nano Development Board and Target Detection through Tensorrt
The NVIDIA Jetson Nano Development Kit is a low-cost AI computer. It provides computing performance that runs modern AI workloads in an unprecedented scale. It has extremely high power efficiency, power consumption is only 5 watts. It is supported by NVIDIA JetPack for the entire NVIDIA Jetson series, which reduces developers, learners and manufacturers' complexity and overall workload.
The NVIDIA Jetson Nano development kit provides computing performance that runs modern AI workloads before, power and cost. The developer suite can be powered by Micro-USB and provide a wide range of I / O, range from GPIO to CSI. This allows developers to easily connect various new sensors to support various AI applications. Its power efficiency is incredible, and power consumption is only 5 watts. Jetson Nano also supports NVIDIA JET PACK, which can use the SD card images that are easy to flash, so that it starts quickly and easily. The verified software stack reduces the complexity and overall workers of developers.
This video will demonstrate what Jetson Nano can do through depth learning object detection examples?

TOP1: Create a simple circuit board small batch production line
Time to make the Rubik's Cube 3 to contact this production method. In fact, it is also produced in the factory, but all steps can see the company's financial power to automate the machine.
For example, the ornament is replaced by a patch machine, and the print is replaced by a machine, and so on.
It is also gradually decreasing the price of the factory patch now, and if the batch is large, it is more provincial practice.
