Goose sister! AI hardware, you can do it yourself!It only takes one hour and the cost is less than 800 yuan.. It can record people’s conversations and environmental sounds to a private database at any time, and customize the exclusive AI assistant. andThe whole process is completely open source.All the data collected are controlled by the users themselves.

In the promotional video, the author shows his private GPT formed after wearing this device for several days. The author said that he has been discussing this hardware with others in the past few days.

When he asked about his big model, he could see that the model had learned what the author said these days and introduced his wearing equipment in great detail.

Moreover, the whole system can DIY by itself.The hardware cost is only $100, about 720 RMB. However, the brand AI in the market is expensive at six or seven hundred dollars, and some of them only pack software services for one year. The key is that they are not in stock yet.

This system has caused a burst of cheers from the open source community. Some people say that the Linux time for AI to wear has arrived.

So, how does such an AI hardware DIY?

Structurally, the whole system worn by this AI mainly consists of the following four parts:

Let’s look at the hardware first. The current hardware consists of a Coral AI development board ($80) and a Wifi module ($20).

The plastic box outside is optional and costs $10.

Because the two boards come from the same manufacturer, the hardware assembly process is very simple, just plug them together.

Next, we need to register a database account and get the API.

Then install the database client and docker on your own computer or server, and configure the database and App server according to the tutorial. The detailed process of this part can be read on the author’s GitHub project page.

Prepare the software and hardware, and then write the program for the board.

After connecting to the computer with the type-C data cable, it is also a step-by-step operation to complete the compilation and upload. In this process, you need to write the WiFi name and password to the device.

Then, such an AI wearable device is done. Then, as long as you wear it with you, you can build your own large model database according to your own conversation.

If you are interested, you can try it yourself! (See the project portal at the end of the article)

$100, which is far from the lower limit of hardware cost-

The author plans to try to replace Coral development board with cheaper raspberry pie soon.

The raspberry pie Zero W with integrated WiFi module costs only $15. If it succeeds, the cost will be directly reduced by 85%.

In addition, the SD card can be inserted, so in addition to reducing the cost, the use of raspberry pie can also localize the cloud database.

At the same time, the author also plans to add Bluetooth and other communication methods in addition to WiFi, so that it can truly become a portable device and upload data anytime and anywhere.

Since Coral’s WiFi module also supports Bluetooth, this operation only needs to update the software without replacing the hardware equipment.

In view of the problem that there is no battery and external power supply is needed, the author has initially chosen a battery device, and it is expected that there will be a solution soon.

[Original of Truck House] When we truck drivers buy oil, we can see numbers like 15w-40 or 20w-50 on the outer packaging of the oil, and words like API CH-4API CI-4 can also be seen below. These are the labels of the oil, so what do these labels mean?

● 　SAE 15w-40 What does all this mean?

SAE in the front is the abbreviation of American Society of Automotive Engineers, and the viscosity index of engine oil is formulated by them and is universally used. 15w-40 in the back represents the viscosity index of this engine oil. At the same time, this label also shows that this engine oil is a multi-grade engine oil, and the current civil engine oil has no previous single-grade engine oil, that is to say, it can be used all year round, so let’s take 15w-40 as an example to illustrate the meaning now.

"W" means winter. The smaller the number 15 in front of it, the better the low-temperature fluidity of the oil. 15W means that the oil can be used in the environment above minus 20℃. The number 40 at the back represents that the kinematic viscosity of this oil ranges from 12.5 mm/s to 16.3 mm/s at 100℃, and other viscosity indexes also have corresponding standards, which is by no means what some people say can be used at 40℃.

● 　What does API CH-4 mean?

API is the abbreviation of american petroleum institute, followed by CH-4, C, and H after diesel oil. S stands for gasoline engine oil, and n stands for the grade of the gasoline engine oil. If it is marked as SN/CF, it is a general-purpose gasoline and diesel engine oil.

According to different letters, the grades of engine oil can be arranged, and the lower the letter, the better the performance of engine oil. And the engine oil with the lower letter has more examples of meeting the emission standards. Now, because of the post-treatment, the vehicles discharged in the fifth national standard generally use engine oil above CI level.

● What does ACEA certification mean?

ACEA is the abbreviation of European Automobile Manufacturers Association, which is the inspection and certification standard for automobile lubricating oil in European automobile manufacturing industry. From the technical requirements, it is higher than the American API standard mentioned above. Many of our big-name engine oil packages will see the relevant certification of ACEA, so you can carefully observe and compare them.

ACEA’s certification of heavy diesel engine lubricating oil is divided into four grades, namely, E2, E3, E4, E5, E6, E7 and E9. Similarly, the higher the number, the higher the grade of engine oil. Generally, big-name engine oil will certify these corresponding grade standards at the same time. You can carefully observe the marks on the barrels.

● 　So how do we choose?

Generally speaking, when choosing engine oil, you should first refer to the requirements in the vehicle manual. For example, this car requires the use of 15W-40 CH-4 engine oil. In practice, we can not only choose the engine oil with this grade and viscosity according to the instructions, but also raise the engine oil level by one grade, that is, we can use CI-4 engine oil with 15W-40 viscosity, which will better protect the engine and promote the emission standards.

If your local temperature is below-25℃ in winter, we can choose engine oil with viscosity of 10w-40, which will make the cold start smoother and ensure that the engine oil can be pumped to the friction surface during cold start. Just remember one thing, the last 40 remains the same, and the small number in front has no effect.

If it is an old engine, you can choose an oil with a slightly higher viscosity, such as 20w-50. For an old engine, the oil with a slightly higher viscosity can better protect and maintain the normal operation of the engine. (Text/Jiang Yitu/Jin Zhu Jiang Dai)

All the engine oils in Truck House Mall are genuine. Please poke the above picture for details.

It is not easy to buy a house, especially for most buyers who just need to buy a house. It takes all their life savings to buy a suite, so the process of buying a house becomes cautious, and many opinions will be consulted when making a decision. Then what kind of property can’t be touched? Today, Sister Fang will take stock of those notorious "rotten late nights" in Wuhan for you. If you meet them, make a detour! (The following rankings are in no particular order, so pay attention! )

I. Impression of Hankou

Speaking of Hankou Impression, I think everyone is no stranger. It has been nearly three years since the three units of Building 1, the first phase of the project, were officially opened for sale on December 9, 2013.

Located at the intersection of Machi Middle Road and Huanhu Middle Road in gold and silver lake, the once-crown-selling building in gold and silver lake was snapped up when it opened in daylight. Pre-sale began in 2013, and more than 600 suites were sold in batches in 2014. Unfortunately, in just one year, this place has changed from being hot to being spurned by ten thousand people.

At present, there is still a funding gap of more than 20 million in Hankou Impression. However, there are more than 700 houses in Hankou impression, and more than 600 houses have been sold at present. Where did the sales funds go? Why is there a funding gap? According to Yang Kechang, the development department of Housing Management Bureau in Dongxihu District, Wuhan, Hankou has a bad impression. They have held coordination meetings many times in the early stage, and developers are actively cooperating with financing. This may take a process. When can the house be delivered? Everyone expressed doubts!

Second, China Chinatown

Last year, the bankruptcy of the cornerstone of wealth was still fresh in everyone’s memory. Most of the money invested by clients went to Shui Piao, and the "Hong Kong Road Chinatown" raised by the cornerstone series was also implicated, which led to the capital chain, and now it has reached a deadlock.

Among them, some owners bought some shops on the second floor of Chinatown at a price of 19,000 yuan/square meter, and they also faced the dilemma of not getting the real estate license. According to the architectural plan, the two underground floors of Chinatown on Hong Kong Road are parking lots, not shops.

According to the website of Wuhan Housing Authority, several buildings sold by the company have obtained pre-sale certificates in 2011, but they have been delayed in handing over the house. A staff member of the sales department of Chinatown on Hong Kong Road said that the main reason was that the subway on Line 6 was under construction, which affected the company’s water and electricity installation. It was originally scheduled to be delivered at the end of 2013, and now the delivery time can only be postponed. If it is not properly disposed of, it will face a rotten tail.

Iii. International Lido

The break of the capital chain is the direct cause of the shutdown of most real estate projects, and the owners of Lido International are eager to wait for the project to resume work. After many years of rights protection, the owner and the developer signed a penalty-free contract.

About the problems in the developer’s capital chain, almost all the owners and surrounding residents know. The public reports of the media did not relax them. Because the developer promised to hand over the house on October 31, 2015, it was not fulfilled. The owners have broken their hearts for this house.

Fourth, your family

The mansion property is located in the advanced brigade of Jinyin Lake in Dongxihu District. The first phase includes 512 sets of non-blank houses in residential quarters and 108 suites in villa areas. Among them, 479 sets of 512 houses have been sold, and the original plan is to hand over the house in December 2013 and June 2014. However, when the house was handed over, most houses were not equipped with floors, residential roads were not completed, and water and electricity were not completed. More than 30 owners can’t bear the economic pressure to stay in uncompleted residential flats, and some even climb 32 floors to go home on foot.

According to master tong, who contracted the first phase of non-blank residential quarters in Fushang, the materials were provided by the developer, who was only responsible for decoration, and the floor and doors were installed by the supplier; Because some materials are not in place, there is still finishing work in the decoration. At present, the developer Shengyang Real Estate owes him tens of millions of yuan in wages, and his monthly interest on debt is more than 300,000 yuan. It is understood that Shengyang Real Estate still owes 56 million yuan to the construction unit.

V. Xu Dong Jiangshang

The property was postponed for three times, which made the owner unbearable. Jiangshang opened on September 15, 2013, and the delivery time indicated at the opening was September 2014. However, when the delivery date was approaching, the developer suddenly issued the Notice of [Jiangshang] Delayed Delivery to the owner, which changed the delivery date to December 2014. The owner said that after the developer’s first extension, the project property was still on sale, and the statement that "the property will be delivered at the end of 2014" attracted many new buyers. However, at the stipulated delivery time, the developer stood up again. For the developer’s second break, some owners defended their rights on December 28th, 2014. On the day of rights protection, the developer extended it again, saying that the house will be delivered on September 28th, 2015, and the liquidated damages will be settled together when the house is delivered. This delivery date has been one year later than the initial delivery time.

Buildings 2, 3 and 4 sold by Jiangshang received pre-sale permits in 2012 and 2013 respectively, and the delivery date for filing was also September 28, 2014. But so far, there is no public notice of the completion of these three buildings in official website, which shows that the conditions for handing over the house are not yet available. There are rumors that the property can’t be delivered because the developer’s capital chain is broken, and the progress of the project is difficult to advance. Some owners want to return a house through legal channels but are told by the developer that there is no money to return.

CCTV News:In order to build the whole agricultural industrial chain, the central government has also accelerated the guidance of key links in the industrial chain from cities to counties and villages. In Chaotian District, Guangyuan City, Sichuan Province, the industrial space has been greatly expanded because of the storage cold chain logistics facilities.

In the past two days, the edible fungi of Yangmuba in Chaotian, Sichuan began to be picked and listed. Unlike in the past, they only produced edible fungi. Now, their industrial chain has extended to the secondary and tertiary industries such as processing and transportation, and their income has increased a lot.

However, in the past, the cold chain transportation of edible fungi in Chaotian relied entirely on the logistics companies in the city. In the event of mudslides, rainstorms and other disasters, the supply of fresh edible fungi would be cut off, and the best sales opportunity would be missed in vain.

In the past, the situation of short industrial chain and low value-added income in rural areas like Chaotian was widespread in rural areas throughout the country. In order to build the whole industrial chain of agriculture, the central government guides the key links such as processing and circulation of agricultural products to sink from cities to counties and villages, and expands the coverage of production to the whole industrial chain, so that production, marketing and agricultural tourism can be seamlessly connected in counties.

In 2020, the central government invested 5 billion yuan to start a pilot project for the construction of cold chain logistics facilities for storage and preservation of agricultural products. This year, another 8 billion yuan will be invested to promote agricultural products nationwide, so that agricultural products can be sold from raw materials of "original brand name" and "initial brand name" to fresh products and brands.

Last year, Sichuan Chaotian built a storage cold chain logistics facility, which not only solved the problems of storage and transportation at once, but also attracted many repeat customers because of the fresh ingredients, and the products were not worried about sales.

　　Cctv news (Reporter Li Wenliang) Science and technology promote the transformation and upgrading of the manufacturing industry, and also bring infinite possibilities to future life. On December 4th, the interview group of "High-quality Development of Manufacturing Industry" went into Hisense Development Research Center and Teld New Energy Co., Ltd. in Qingdao, Shandong Province. Here, you can not only experience the comfort and convenience brought by smart homes, smart communities and smart cities on the spot, but also imagine the smart transportation in the future through the development of new energy vehicles.

　　You can chat on TV and the computer can assist in surgery.

　　At Hisense Development Research Center, reporters saw that TV has a new way of playing. Besides viewing, it also has social functions. Users can chat with friends online while chasing dramas. The new self-developed Hi Table large-screen interactive system makes social interaction no longer limited to mobile phones and computers, but also integrated into home audio and video.

　　Based on the integration and accumulation of 5G+AI+IoT technology, the Internet Unicorn Company under Hisense has taken the lead in launching full-scene picture search and AI voice in the industry, and a TV has opened 13 major life scenes such as clothing, food, housing, transportation and entertainment. In August this year, through the new interactive upgrade of big-screen social interaction, 6-way video calls and other functions can be realized, providing full-scene smart life services for families.

　　In addition to paying attention to family entertainment, Hisense will also focus on the construction of smart communities and smart cities. In the smart community section of the center, there is a demonstration case of Hisense’s participation in precision medical surgery. With the help of Hisense CAS (Computer Aided Surgery System), medical personnel can create 3D model images based on two-dimensional images such as CT, which can not only accurately restore the real state of tissues, but also provide images of separation and reconstruction of arterial and venous blood vessels, and truly assist in the whole process of surgical indication judgment, scheme planning, step simulation and intraoperative navigation. At present, Hisense’s independent data service and some tracked hospital data total more than 6,300 cases.

　　New technology turns new energy vehicles into "super charging treasures"

　　In the future, electric cars may bring us more surprises.

　　According to the national plan, by 2030, the scale of electric vehicles in China will reach 100 million, and the annual charging capacity will be as high as 460 billion kWh.

　　"Electrification and new energy have become the development trend of automobiles. According to the concept of vehicle networking, the biggest change of electric vehicles is to change them from the original traffic attributes to new intelligent carriers carrying big data, and also to mobile energy storage equipment". Zhao Jian, brand general manager of Qingdao Teruide Electric Co., Ltd. said.

　　The battery of electric vehicle is a natural mobile energy storage device, which can move across time and space with energy. We can charge in place A today and discharge in place B tomorrow. At the same time, as an electronic product, electric vehicle contains a wealth of data, such as user behavior information, vehicle information and so on, which we can analyze and utilize. Therefore, in the future, electric vehicles can not only pull people to pull goods, but also "pull energy" and "pull data".

　　Now, Teruide is building an ecological cloud platform with the largest "three networks integration" of charging network, vehicle networking and Internet in China. Independent charging terminals form a charging network through physical connection and intelligent regulation, and the charging network breaks the barrier between the vehicle networking and the Internet through the extraction and transmission capacity of data information, forming a new industry with two-way deep integration of new energy and new transportation. In the future, it is hoped that the charging network, electric vehicles and distributed energy storage will be able to feed back the national grid.

　　Charging for 40 seconds, battery life for 10 kilometers, unmanned intelligent charging to open a "new era"

　　With the maturity of artificial intelligence, bus-assisted driving and unmanned dispatching technology, urban public transportation will become the most qualified industry to take the lead in realizing unmanned driving.

　　In September this year, the "Super Smart Charging Bow" was officially opened in Shanghai Bund, which is the world’s first intelligent charging device developed by Qingdao TELD New Energy Co., Ltd.

　　This charging device, which is integrated with the bus stop sign, may not attract the attention of Shanghai passengers, but it charges the bus quickly between passengers getting on and off, and it can last for 10 kilometers in 40 seconds. Moreover, the intelligent charging bow also has unmanned operation functions such as automatic identification, automatic matching charging, intelligent cloud management, intelligent erasure of foreign body detection, multi-contact lap connection, etc., which can automatically realize pressing and docking charging, and the whole process is separated from manual operation. Bow lowering and charging are completed with one button, which is the first in the world to realize intelligent control and unmanned operation of charging, and will be the perfect solution for unmanned driving in the future.

　　At present, the intelligent charging bow has been used in Shanghai, Chengdu and Wuhan.

1905 movie network news Recently, the film "93 International Train Robbery: Moscow Action" (hereinafter referred to as "Moscow Action"), which was jointly produced and directed by, released a special edition of "All the members are two-faced", and the stars gathered to stage a wonderful story of fighting wits and courage. Andy Lau,,, and performed a "double-faced life", in which all the members were full of life.

In the special edition, Andy Lau plays Vasily, who is a snake-head with a sky-high hand and eye in Moscow, but he misses his daughter, and the identity of his father becomes his only weakness. Cui Zhenhai, the police captain played by Zhang Hanyu, can only pretend to be a debtor when going abroad to handle cases. Miao Qingshan, the robber leader played by Huang Xuan, is arrogant and arrogant, but he actually has a pure place to love music in his heart.

Li Suzhen, played by Janice Man, as a member of a criminal group, undertakes the task of stepping on a plate, but she is kind-hearted and family-oriented. Miao Ziwen, played by Jason Koo, is moody and violent, but emotionally vacillates between her brother and girlfriend.

Some viewers commented: "The 1990s is an era of earth-shaking. We have seen many stories on the ground, and the real stories are more thrilling and exciting, courageous and thoughtful, affectionate and righteous." As co-producer Andy Lau said, "I think we can discuss some deeper things, such as what human nature should be, under a story of police and bandits."

As the only criminal action blockbuster on the National Day, the action scene of the movie "Moscow Action" burst in visual effect, and the climax was wonderful. The audience called it "the highest level masterpiece in the past three years" directed by Qiu Litao: "Too angry, too fierce! Based on historical cases, cross-border arrest is the main line, and a number of escalating action scenes have been connected in series, one by one! "

The superb acting skills of the actors also convinced the audience: "Andy Lau’s role is a sad symbol under the changes of the times. Although he is also a’ villain’, the character itself is not bad. This line with his daughter really pokes tears." "Zhang Hanyu has always been a decent and capable policeman, with agile skills and a tough guy." "The casting is impeccable. Huang Xuan plays the bad guy really, and he plays hard and crazy." "Janice Man’s appearance is varied, he is actually brave and resourceful, and he can make the right choice unambiguously at the critical moment and create a classic role."

1905 movie network news Recently, the highly talked-about event is the breakup between Andy and michael. On August 12th, it was reported that Sophie was suspected to have intervened, which led to the breakup between michael and Andy.

Later, Sophie Studio came forward to refute the rumor, saying, "I don’t accept rumors, and I don’t take back the pot." It was suspected that I denied the rumor that Sophie broke up with Andy and michael because of their involvement in their feelings.

On the same day, Andy and michael Studio released a statement at the same time announcing that they broke up, saying that they had recently ended their relationship and became friends again. In the process, they had nothing to do with others and had no betrayal. Many netizens are still immersed in the hot search of the interaction between the two in the crew. However, the news that the two broke up after nearly a week has made many netizens feel wrong.

In fact, it was as early as six months ago that the video of Andy crew visiting michael sitting on his thighs was filmed. Attentive netizens also found that michael, who was still an official boyfriend at that time, had never promoted Andy in two works recently launched by Andy.

Many netizens questioned michael’s cheating and his relationship with Sophie, and even pointed out that they were too close on the set when they cooperated.

Andy also admitted to Mr. and Mrs. Tamia Liu when she participated in the recording of the variety show Dear Inn last year that she dreamed that michael was in love with the actress in the same group, and she woke up with tears: "I dreamed that my boyfriend was in love with the actress in his same group, and the people in their crew were indifferent to me, and then I cried. I dreamed that the director of "Zhu Xian" with his staff shouted at the bottom,’ Come on, Andy, you have to cheer up, we are going to film’, and then I woke up with a start, and I was scared. The dream was particularly clear. Today they have already filmed the wedding scene, and I am very sad. "

As the incident fermented, Andy also criticized Weibo in Sophie’s studio, saying, "The problem of personal feelings has nothing to do with snow welcoming".Sophie then replied with a hug expression, and paid attention to each other with Andy that day.Recalling that they went to Thailand to record "High Energy Youth League" at the end of June, they also got along well, and there seems to be no sign of disagreement.

However, today (August 13th), some netizens found that Sophie himself, Weibo, praised an ambiguous video of sharing a bowl of Hu spicy soup with michael in the crew. Subsequently, although Sophie himself withdrew his praise, he still made "Sophie Like" rank first in the hot search list. To this end, some media verified the staff of Sophie, and the other party replied that "it is to turn Weibo’s hand to slip." However, the relationship between the three people has also caused more speculation.
