Large

Electronic alarm clock*1
High current relay*1

Car speaker*1
11.1v lithium battery*1
One way wireless module*1

Small pieces

Hole plate
Ss8050*2
Capacitance 4.7uf 16v or more*1
T plug *1
Switch wire self-tapping plug spring strip

Function: Replace the buzzer of the electronic clock with a car horn. Why use a wireless module. This alarm clock is definitely not possible to put it on the bedside. But you can't close it, so add one. Wireless module to turn off the alarm (press the "Snoozing" button)

I am no longer woken up, but I am scared




Here's the production process:

Take the alarm off

Screw two bases on the housing

Below is a photo of my test drive circuit

Circuit diagram
(Generally, the buzzer of the electronic alarm clock is connected to the power supply at one end and the buzzer is controlled with the low level at the other end. So here only the negative pole of the alarm power supply and the "negative" side of the buzzer are connected)

Next, put the horn on a wooden board first.

Next, take the line in the alarm clock and fix it on the board (I drilled four holes on the board and fixed it directly with a plastic strap)

Welded plate (where a large current is used, I used a tin strip to lead the soldering relay. I can put the spring on the board and put it on the board in the appropriate position and then solder it in the way of "sMD" (I use a double panel) ))

T-plugs and switches are also "patch"

Connect the alarm clock and board to the circuit diagram

After loading it on the board, I made two strips of holes on the board. I used the Velcro to tie the battery.

after finishing:

Small size... a palm can hold the base

Why is Jack Ma doing charity?

A few days ago, the retirement of Jack Ma was a sensation in the global business circle. Jack Ma said that after retirement, he will put more energy into public welfare and education.

So when it comes to charity, you have to talk about Jack Ma's old friend Bill Gates. Jack Ma said: I learned a lot from Bill Gates, and it is likely to follow Bill Gates to set up his own foundation.

For Jack Ma's move, Gates said, "I haven't talked to Jack Ma about this decision personally, but I look forward to having the opportunity to talk to him because I believe that he will have a lot of gains as he joins in charity. I will understand the philanthropy in the Chinese context. I hope he can bring the new thinking and new energy that has created Alibaba to charity."

Gates strongly praised the success of Ant Financial in the digital field. "Ant Jinfu has sufficient experience in digitizing the currency and reducing transaction costs. The Gates Foundation has been paying attention to inclusive finance and has also cooperated with Ant Financial. Promote digital currency to places like India."

Still more netizens said: Why Ma Yun is going to be charity, it is to learn Bill Gates!

Regarding Bill Gates, I believe that everyone is familiar with it. Someone asked Bill Gates before, why not want to run for the president, and Bill Gates’ answer is that he is more willing to do charity because he likes it because there are too many people in the world. Their help.

In January 2000, Bill Gates announced his retirement as CEO of Microsoft and established the "Bill & Melinda Gates Foundation" with his wife Melinda Gates. Since its inception, the foundation has donated With approximately $36 billion, it is the world's largest private charitable foundation.

At the same time, Bill Gates also encouraged young American entrepreneurs to be like him, such as Zuckerberg. Under Bill Gates's rendering, a foundation called "ChanZuckerberg" in the name of her own and her wife's surname will be established to promote equality and children's rights, and to create a better world for her daughter. Facebook official said that Zuckerberg’s donation is independent of the company, and Zuckerbock is still the actual controller of Facebook in the foreseeable future.

At the same time, Bill Gates and Jack Ma have one thing in common, that is, they are very concerned about young people, and the so-called young people are the hope of the future.

Bill and Melinda Gates are optimistic about the current growing population of young people who believe they are the new force driving progress. Investing in the health and education of young Africans will unlock productivity and innovation potential and bring about the “third wave of poverty reduction” following China and India.

Jack Ma is speaking in many places around the world, encouraging young people to learn to innovate, because the future world will be an innovative world for young people, and also use Alibaba's resources to serve young people.

The lady put on the mechanical bones and changed the Hercules: easily lifted 45 pounds of heavy objects.

Technology has changed lives. The development of mobile Internet, smart phones and Internet of Things has completely changed the quality of your life. So what is next? May be turned into a "superhero." Cnet editor Lexy recently tried on the SuitX mechanical skeleton and experienced the feeling of becoming a Wonder Woman.

The SuitX mechanical skeleton is divided into three parts, including the ShoulderX for the upper body, the LegX for the lower body, and the BackX for the protective accessory. The dressing process is not complicated, but you still need someone to help.

After wearing SuitX, the activity did not become inflexible. Of course, SuitX is currently used in industrial production, such as the heavy production of assembled cars.

After Lexy puts on the SuitX, it is easy to lift the box with 45 kg of lead, which is effortless and the second becomes the Hercules.

If you do a half-turn, you can stay for a few hours without getting tired, and your knees and ankles will not be damaged.

In order to show the super-assisted power of the SuitX, Lexy also stepped on the treadmill and ran for a while at a speed that could not be sustained at all, very relaxed. Of course, this does not work well.

Although SuitX is currently only used in the industrial field, it is positive for the future of mankind. With the continuous development and maturity of technology, the mechanical skeleton will become lighter in the future, improve the quality of life of the disabled, the elderly, and ensure the safety of the police and security personnel, which will make the world a better place.

Airbus’s drone “pseudo-satellite” stayed in the air for 25 days, refreshing a flight record

Airbus' Zephyr S spy drone has been in the air for 25 days, setting a record for the longest flight duration in the Earth's atmosphere.

The Zephyr S is powered by the sun during the day and charges the lithium-sulfur battery for battery-powered nighttime. It has a wingspan of 22.5 meters and can be launched from the shoulders of four soldiers.

The Zephyr S has been in development for more than a year and will be used by the British Army as a high-tech aircraft to monitor targets around the world. Airbus will also develop the Zephyr T.

It is known as a "pseudo-satellite" - where there is no satellite signal, Special Forces soldiers can fly the drone, using a control station to fly within 400 kilometers to function as a satellite.

It can fly at 70,000 feet (21,000 meters), which is twice as high as commercial aircraft.

According to Agence France-Presse, in addition to national security uses, the drone will also be used for maritime surveillance, border patrols and forest fire detection missions.
