[Electronics] Homemade minecraft galaxy mod advanced solar physical model

This is a solar charging treasure for holiday.
The shape is modeled after the advanced solar energy in the minecraft game galaxy module.
The original shape is to make a solar generator in an industrial module, almost like this:

      I want to make the outer casing small, but the solar panel is too small and the power is not going up.
I also considered that four small solar panels were folded into the outer casing and opened again when the sun was shining, but the power was still too small and it was more troublesome to make it.
So decided to still be a solar generator in the galaxy module.

    First come to the full picture
 

This is a lithium battery charging board plus protection board, step down to 4.2v

The other one is the charging treasure module with display. When the solar charging, the load is disconnected, so a switch is added.

Connected in parallel with 4 sections of 18500, with a total capacity of 5600mah, charge test

     Data for this monocrystalline solar panel
     I am afraid that it is not clear after uploading
     Hand hit, single crystal, working voltage 6v, working current 750ma, maximum output power 4.50w, open circuit voltage 7.3v, short circuit current 836ma, size 165*165*3mm

Find a broken compass

Usb interface, solar cells can be separated from the main body.

The circuit part is just like this. Originally, the Schottky diode anti-backlash was purchased. However, after testing, the buck module comes with anti-backlash.

3mm light wooden board

Hot melt glue is good, it is stuffed in.

The amount is painted with Tushan Susu.

The magic of card stickers, haha

I am sorry to be rough.

Efficiency is still not measured, after all, it is solar energy. The main thing to do is to restore the game, put it on the table to decorate, and spend the boring holiday time.

Redo the classic! "XiaoShangdi" power supply 0-35V 0-5A adjustable constant current

A once popular power supply, the "XiaoShangdi" teacher's classic power supply adjustable constant current 0-35V 0-5A.
         Do it again in a few years, huh, this time is a double panel.
   
   1. Time-consuming and effortless double-sided full-line PCB: 10*10CM
       

    2. Turn over the cabinet, add the disassemble and purchase, and finally get the components together:
         The cable is also readily available for external components.
       

   3. Use a power supply main control board that has been soldered for one afternoon: 0-30V
     (I only have a dual 12V transformer, one winding less than the drawing design)
     

   4, right, there are still close-ups of the 1602 header:
     

   5. Connect and install all the peripheral accessories except the case, the next step is to debug:
       

   6. Stay away from the board and worry about the power, although I think it is very careful.
        One of the 470uF electrolysis still exploded (the polarity is reversed),
     After adjustment and replacement, try it, 0-30V adjustable, basically normal use! Oh, success,
      The test data of each indicator is to be continued. . . . . The 1602 meter performance is also to be tested. . . . .
 
    7. Attach the original original picture of Teacher XiaoShangdi:
       

    8. I believe that many of the power friends have done this, there are many posts on the Internet to make this power.
         Please also give me some pointers, thank you,

Intel Fall Conference: The ninth generation of Core released the main frequency soared to 5GHz

On October 8th, Intel held an autumn conference in New York, USA, and launched a number of new generation processors and chipsets, including 8-core 16-threaded nine-generation Core, 18-core 36-thread new Core X and 28-core 56 threads. Xeon W-3175W processor.

Intel's nine-generation Core processor: 8-core 16-thread, 5GHz, brazed heat transfer
This nine-generation Core processor uses a new package, up to 8 cores and 16 threads, 5GHz frequency confirmation, and the best news is that Solder TIM confirmed that the silicone grease U is really goodbye.

After so long, the nine generations of Core has no mystery, the architecture is Coffee Lake-S, the process technology is still 14nm++, but upgrading to 8 cores and 16 threads and single-core, dual-core Turbo 5GHz also make up for multi-core performance and sharp The Dragon 7 series processor is a bit hard (although Intel's multicore performance on the current 6-core processor is not bad).

The key to the natural is the Core i9-9900K processor, Intel said it is the first 5GHz high frequency original brand processor (Core i7-8086K crying in the toilet), the first mainstream 8-core 16-thread processor (Ruilong 7 said that it is not convinced), if these did not touch you, then Solder clamp welding should be able to conduct heat, this has plagued Intel processor players for 6 years, from the beginning of the 2012 IVB processor to the full turn of silicon Fat, last year's Core i9 is no exception, this year Intel changed back, although only a few high-end models.

The Intel 9th ​​generation Core processor will be available for booking on October 19th and will be available on November 5th.

Nine generations of Core architecture and 14nm++ process

Intel talks about the benefits of Solder TIM brazing heat conduction

The specific models and specifications of the 9th generation Core processor

Core i9-9900K: 8 cores and 16 threads, 16MB L3 cache, 40 PCIe channels (16 CPU + chipset 24 tricks), dual channel DDR4-2666 memory, base frequency 3.6GHz, acceleration frequency 5.0GHz, TDP 95W, The price is 488 US dollars (8700K is the recommended price of 359 US dollars).

Core i7-9700K: 8 cores and 8 threads, 12MB L3 cache, 40 PCIe channels (16 CPU + chipset 24 tricks), dual channel DDR4-2666 memory, base frequency 3.6GHz, acceleration frequency 4.9GHz, TDP 95W, The price is $374.

Core i5-9600K: 6 core 6 threads, 9MB L3 cache, 40 PCIe channels (16 CPU + chipset 24 tricks), dual channel DDR4-2666 memory, base frequency 3.7GHz, acceleration frequency 4.6GHz, TDP 95W, The price is $262.

Comparison of specifications of eight generations of nine-generation Core processors made by Anandtech website

Although it seems that the acceleration frequency of the two generations of processors is the same, the 9900K full-core acceleration is 4.7GHz, the 8700K is 4.3GHz, and the multi-core frequency is greatly improved.

Nine generations of Core performance comparison, the above column is compared to the previous generation, the next column is compared to the computer three years ago

Intel's new generation Core X processor
The Core X series processor has also been updated, although it is still up to 18 cores and 36 threads, four channels of memory, and 68 PCIe channels (24 of the 44+ chipsets), but this time the processor was changed to Solder TIM, which is to change To clamp the heat conduction, no longer use silicone grease.

Upgraded Core X processor architecture and specifications

Specific models and specifications

Although this Core X still has a maximum of 18 cores and 36 threads, but changed the heat of the clamp welding, the specifications have changed, the name has become the Core i9-9XXX, corresponding to the current Core i9-7XXX, such as the top is the Core i9- 9980XE replaces the current Core i9-7980XE, still 18C/36T, 165W TDP, four-channel DDR4-2666 memory, base frequency 3.0GHz (7980XE only 2.6GHz), acceleration frequency 4.4GHz, TB 3.0 acceleration frequency 4.5GHz (than 7980XE) Up to 100MHz), the price is 1979 US dollars, this price is the same as the current recommended price, the overall change is the frequency has been improved, replace the thermal material, and then upgrade without price increase, other models as usual.

Performance comparison, this time to pull AMD's 32-core TR 2990WX out to play a meal, to know that this is rare, indicating that AMD deserves Intel's attention.

Intel Releases 28-Core Xeon W-3175WX Processor
Last year, Intel introduced the 18-core 36-thread Core X series processor, which successfully suppressed AMD's 16-core thread tearer. At the Taipei Computer Show in June this year, AMD released the 32-core 64-thread second-generation thread tearer. Intel also showed a 28-core processor at 5 GHz, but it was just a show at the time. The 5 GHz is also an overclocking of the water-cooled machine. The intention of Intel to introduce a consumer-grade 28-core processor is uncertain. Just at the autumn conference, Intel really launched a 28-core 56-thread processor, but not the Core series, but the Xeon W-3175X, frequency 4.3GHz, for creators, positioning with AMD's 32-core Threadripper 2990WX is a bit similar.

For the 28-core processor, Intel has no technical problems with such a product. The processor of the Skylake-SP architecture did it last year, but it is mainly used in the server market. The 28-core processor Xeon W-3175W is launched this time. The processor should be a variant of the Xeon Platium 8180/8176F/8176 processor.

Xeon W-3175X processor architecture

Regarding the supported motherboards, although everyone guessed that it is a new X599 chipset, the C621 motherboard is still on display. Considering that the Xeon W-3175X is still a professional application processor, this time it is normal to not push the X599. It should be left to the future consumer-grade 28-core processor platform, if Intel really intends to.

28-core Xeon W-3175X processor specifications

The Xeon W-3175X processor is 28 cores and 56 threads, 38.5MB L3 cache, basic frequency 3.1GHz, acceleration frequency 4.3GHz, 68 PCIe channels (still 44 CPU + 24 chipsets), TDP power consumption 255W, 6 channels of memory, up to 512GB ECC memory.

The price of the Xeon W-3175X processor has not been announced and is expected to be available in December.

Intel released Z390 chipset
In order to realize the full potential of the new ninth-generation Intel Core processor, Intel announced the launch of the new Intel Z390 chipset. The Intel Z390 chipset includes an integrated USB 3.1 Gen 2 high-speed port and integrated Intel Wireless-AC adapter to support Gigabit WiFi. In addition, the ninth generation of Intel Core processors are compatible with all Intel 300 series chipset motherboards, providing consumers with more choices. From now on, Intel global distributors and retailers are beginning to accept bookings for the ninth generation of Intel Core processors and Intel Z390 chipset motherboards.

Will the robot look so realistic and will you refuse?

With the development of technologies such as simulation and artificial intelligence, it is no longer difficult to create a humanoid shape with high artificial robots. However, careful friends will find that most of the current simulation intelligent robots look like women, and they can’t help but ask, is it personal? Are there also gender discrimination in robots?

Perhaps the developers engaged in the field of AI and robotics are mainly male. Yang Jianyong, a senior expert in the Internet of Things, said that for example, Shih-Hai, a world-famous artist, is famous all over the world. Because of his persistence in humanoid robots, he has considerable weight in Japan and internationally. The status has also created the most realistic robot.

Perhaps it has a certain relationship with hormones. Human pursuit of beauty has never stopped. Beauty comes from the pursuit of the opposite sex. Especially the single youth is eager to have a heterosexual companion. The beautiful simulation robot can produce attractiveness to the opposite sex, and also let some Merchants see the economic potential of their hormones.

With the development of technology, the metal/plastic casing of the robot will be replaced by the simulated skin. The beauty robot "Kyoko" in the science fiction movie "Mechanical Ji" is expected to enter the scene of people's life.

Some enterprises or scientific research institutions are pushing the simulation robots to the ground with practical actions, and even designing robots with the appearance of young women. Then, among the various simulation robots, and the simulation robots that combine wisdom and beauty, come to a big value competition. Who do you think is more beautiful?

Japan Androidol U
Shi Heihao, a professor at Osaka University in Japan, is very persistent in the high-profile humanoid robots. He has created a number of women's robots featuring women, and is one of the most representative figures in the world.

Androidol U is also from his hand, beautiful, good shape, and the value is comparable to the star, amazing!

Companion robot Harmony
As the world's first companion robot, RealDoll designed and built artificial intelligence technology to communicate with users, chat with people, and interact with people. The company's person in charge introduced Harmony's original intention to better accompany people. Relieve the loneliness of people.

And has 12 personality traits, including sexy, friendly, shy, etc. The most amazing thing is that there is a heater inside the robot body, which can simulate the real body temperature. This robot, which highly mimics the structure of the human body, can also be customized for the user, including the face and body. It is called "ideal girl", but the price is high, up to 10,000 dollars. However, in my opinion, her beauty is hard to resist.

Like black widow Scarlett Robot Mark1
The Mark1 robot looks like Scarlett outside. The designer is a young man from Hong Kong. He loves robots from a young age. He hopes to build a robot of his own, which has finally come true after a year and a half.

But this robot is relatively expensive, costing 400,000 Hong Kong dollars, just a blond robot, very cool Hollywood star Scarlett, is known as the Marvel hero black widow, but the designer does not recognize that it is created according to Scarlett's appearance of.

Oriental charm robot Jiajia
The China University of Science and Technology released its robot Jiajia, which combines beauty and wisdom. When it was released in 2016, she became a super net red, and the high-value Jiajia was made up of various talents and headlines. .


As a highly imitation of human characteristics, Jiajia is really unclear in terms of falsehood. She is almost a real person and has become a super-net red. She has participated in many important activities.

Robot Samantha
The robot inventor Sergi Santos and his wife have created a robot called Samantha Samantha that has the AI ​​ability to remember the characteristics of the people interacting with it. There are three modes, romantic and family. Switching between different personalities can be switched at any time.

But the inventor is even more radical, even planning to make a baby with Samantha robot, printing it in 3D, but before upgrading, first upgrade the "brain" of the robot, with the values ​​of beauty, justice and human beings. Finally printed in 3D.

At last
From the sci-fi scene, the robot gradually enters the life scene, especially the high-simulation robot. Then, when the beautiful-looking, high-value robot is in front of you, will you refuse?

However, I feel that the "human-machine" relationship has ethical and moral issues, and most people are still unacceptable.

The rise of the robotic customer service era is just around the corner, Google announced the acquisition of AI customer service startup Onward

According to the latest news, Google has acquired Onward, a customer service automation startup, in recent days. The acquisition amount has not been disclosed. Onward co-founders Remi Cossart and Pramod Thammaiah will join the Google team.

The Onward team publicly stated on the company's website: "Our first vision of Onward was to enable smart customer service to interact more naturally with people. By working with Google, we can demand more and more technology for Onward. Support. From the beginning, we were excited about these core technologies, and we are very happy to bring these technologies to Google."

Onward's enterprise intelligence customer service platform can extract information from customer messages through natural language processing technology, and use the geographic location, login status and historical scheduling information to make personalized responses.

The platform is able to make answers to customers through decision trees, making the service process more human. The platform also integrates with Zendesk, Help Scout, Salesforce, Hubspot, Shopify, Spree and Solidus to enable its intelligent customer service to automatically track conversations, add potential customers, and keep a close eye on customers' shopping on these platforms. .

Before Onward's smart customer service debuted, it also launched the Shopping Assistant Agent Q. The software provides product recommendations for people based on customer ratings on the platform. Among them, the artificial agent system and the data summary system will collect the commodity evaluation and commodity prices from various platforms to support the Agent Q service, so Onward regards it as a magic combination of consumer reports.

A few months before the acquisition, Google just unveiled Contact Center AI Virtual Customer Service, a smart customer service system based on machine learning technology that interacts with users over the telephone network. The system is capable of extracting information from customers' voice content and helping customers solve common problems through efficient natural language processing technology. If the virtual customer service can't solve the customer's problem, it will transfer the call to the manual customer service and provide the customer's all the information for the manual customer service. Google refers to this function as “agent assistance”.

Driven by the high-profile deployment of Contact Center AI, eBay's ShopBot and other intelligent customer service services, the global virtual guest market is expected to exceed $1.34 billion by 2024.

John Carmack delivers a speech: Oculus Quest will be the biggest competitor of Nintendo Switch

The Oculus Connect 5 conference officially came to an end. In addition to officially unveiling the mystery of the highly anticipated Oculus Quest, Oculus also demonstrated Oculus Go's updated dynamism and upgraded social network. At the meeting, Oculus CTO John Carmack also made some comments.

John Carmack said: Oculus Quest's biggest competitor to the VR machine is the Nintendo Switch, which is also a portable gaming device.

Oculus Quest PK Switch

In terms of configuration and design, Oculus Quest uses the new Oculus Insight tracking technology, with an integrated camera at each corner and a monocular resolution of 1600x1440. Quest is equipped with a pair of 6DoF handles that sense the user's walking, crouching and tilting movements, allowing users to move freely in the virtual space. Quest follows Rift's design style and is full of technology.

In terms of price, the Oculus Quest is priced at $399, and the price of the Switch is $300. The price difference is not too big.

In terms of experience, Quest can also carry out, but it is definitely more suitable for home experience, users can immerse in the big space. The launch will consist of more than 50 best-selling games, including The Climb and Moss. In contrast, Switch can be used as both a game console and a handheld, making it easier to carry it out. Switch also has several main games, including "The Legend of Zelda: The Wilderness" and "Super Mario: Odyssey".

Carmack said: "I think Quest is a mobile gaming device that is acceptable to existing host users, not a host device like PS4. I think more people will choose Quest than PS4." Quest and Switch are inevitably competing in the market.

Oculus Go still has a selling point

It can be said that the emergence of Oculus Quest fills the gap between the entry-level Oculus Go and the high-end Oculus Rift. However, Carmack does not believe that Quest will completely seize the Oculus Go market. On the contrary, there will still be many people who insist on Oculus Go.

First of all, Oculus Go's cost-effectiveness is not necessary to say.

Second, Oculus Go has the same high "user viscosity" as Rift. Carmack said that Gear VR users usually stop using the device after a day or two, while Rift users "experience and consume a lot of entertainment time every week."

Oculus Go's user retention rate is higher than the earlier Gear VR. The specific reasons are not clear, but in theory it may be that the latter relies on smartphones, and users need to consider battery life issues.

Carmack also said that in the next generation Oculus Go, battery life will be the top priority.

In addition, Oculus Go has also adjusted for features such as frame rate, wearing comfort, and gaze point rendering. Oculus Go will also support the ability to render at the center of the point, by improving the rendering method, focusing on rendering the center area, blurring the rendering around to create a higher quality video.

The good news is that Oculus Go will support Youtube VR and enjoy more videos.

Finally, Carmack also revealed that Oculus Go will also launch the Casting feature, which allows VR users to project content from the virtual world onto another device via WiFi. This is a "great victory" for Oculus, and people will be able to share their VR experience with their friends, which promotes interaction between people.

VR will greatly promote social networking and connect people from all over the world

At the meeting, Carmack described his actual vision of social VR, and he believes that VR will bring people around the world closer together.

However, Carmack does not like to discuss the long-term vision, but based on the present, and hopes to improve the existing equipment. As for the future, Carmack hopes that the development team will be able to optimize 360-degree video more, such as achieving better frame rates and other quality details of VR devices.

Earlier this year, Carmack also announced a video playback technology designed to bring high-resolution video to Oculus Go and other mobile devices, such as support for "Henry VR" video running at 5K resolution. In short, Oculus will continue to optimize its technology and strive to provide a better experience for users.

In the VR era, we are no longer satisfied with "on-screen communication", but need "real scene-style" social interaction, such as seeing the micro-expressions and images of communication objects in a 3D space, rather than simply passing text. Or voice.

It can be said that VR has the unparalleled advantage of traditional devices in social networking - highly immersive. Putting on the head, VR allows users to no longer be limited to space constraints, but to communicate with friends in an avatar, and to share the same virtual space, this experience will far exceed traditional social.
