In elementary school, in order to teach children to cherish time, adults would tell them that an inch of time is worth an inch of gold, and an inch of money can’t buy an inch of time.
I don’t know if anyone has asked such a question. If I have “inch of gold”, where should I go to buy this “inch of time”?
Don’t worry, now this “time machine” has been made in Shizuoka, Japan. The most important thing is that to buy “inch time”, you don’t need gold at all, it only costs 1 yen per minute.
How, is it a good deal?
Once this “time machine” was launched, it was also very popular among netizens. Up to now, the number of likes of this tweet has exceeded 187K likes, and the number of retweets has also exceeded 38K.
The act of buying time with money has been three-dimensionalized. thank you. pic.twitter.com/YpBP2QnqEf

Some netizens can’t help but sigh that when they were young, they felt that money was very important and worked hard all the time. When they became elders, they hoped to be able to use money to buy more time with their children.
When I was young, money was important, so I would do my best to work part-time as an hourly wage, but when I became an old man, I feel like I would spend as much time as I could to spend time with my children and grandchildren.

Some people also said that at this price, it would be 1,440 yen a day, 10,080 yen a week, 43,200 yen a month, and 525,600 yen a year. In other words, if one year is wasted, it is equivalent to a loss of 500,000 yen.
In other words, 1,440 yen for one day, 10,080 yen for one week, 43,200 yen for about one month, 525,600 yen for about one year …
It may be cheap at the conversion rate, but if you think about it at 1 yen per minute, if you waste a year, you will throw it away for nearly 500,000 yen …— Mobs and sugar (@MobCreep) June 20, 2022
It only costs 5,000 yen to build a “time machine”? !
The “time machine” is very simple, a stepper motor, a Raspberry Pi Pico bought in Shinjuku, and a coin picker bought on Amazon.
Coin-operating is entirely based on personal choice, and supports a total of 6 types of coins, ranging from 1 yen to 500 yen. After the coin is put in, the coin selector will recognize the thickness and size of the coin. After receiving the relevant instructions, the circuit board composed of the Raspberry Pi calculates the minutes to be rotated according to “1 yen = 1 minute”, and then transmits it to the pointer. connected motor, and then reverse.
According to producer BB Colley, the production cost of the entire “Time Machine” project is only about 5,000 yen, including about 3,000 yen for the coin selector and 550 yen for the Raspberry Pi. At the same time, he chose to use a stepper motor instead of a normal motor, so that the indicator can stop at the designated position more accurately.
BB Colley recalled that the inspiration for making this “time machine” actually came from chatting with friends. When it comes to “it would be nice to have something like a piggy bank to save time”, relying on the basic A facility engineer’s career is sensitive, and BB Colley completed the entire case over the next nine days, using after hours and weekends.
It’s a way of asking questions to humans
In fact, in modern society, the phenomenon of using money to buy time is very common.
BB Colley said during the interview that in many cases, ordinary people will choose to sacrifice time in order to reduce costs, such as choosing the departure time of trains and planes; in contrast, rich people will hire housekeeping services to reduce costs. More time for work or play by spending time on household chores.
“The rich use their money as if they were charging for their time.”
At the same time, he added that some part-time anchors often complain about the lack of time, or sighs such as “If possible, I really hope to extend the time to more than 24 hours.”
Therefore, “I made this project with great enthusiasm to meet the desire of many people in today’s modern society for time. To put it more exaggeratedly, it is also a way of asking human beings”.
It is not enough to have such creativity, but also to have a certain practical ability.
BB Corrie has been fond of crafting with Lego blocks and empty boxes since he was a child. When he was a student at Kitakyushu National Institute of Technology, he also participated in the “National Institute of Technology Robotics Competition”. After graduation, he also made a lot of interesting gadgets, such as a rock-paper-scissors gloves that can definitely win.
When talking about his own creations, BB Corrie said that many teams or individuals often choose to put technology first, but my work emphasizes the use of digital and analog technology on a “people-oriented” basis. For example, “Time Machine” is also very friendly to people who are not familiar with the knowledge of related fields. In the future, more creations will be used to reflect the concept of daily life and express themes such as the relationship between contemporary people.
Can a time machine really be built?
According to Einstein’s special theory of relativity, time is relative, and as long as you move fast enough, time will slow down relatively.
Will this be a breakthrough for making a time machine?
The Ohio State University astronomer Paul Sutter once said that the faster you move in space, the slower time passes relatively, which scientists have measured from ultra-precise atomic clocks on jet machines; The astronauts on the Space Station (ISS) are actually time travelers. Since the ISS travels at a speed of about 8 kilometers per second, the time of astronauts is slower than that of people on Earth.
American identical twin brothers Mark Kelly and Scott Kelly were astronauts. Brother Mark Kelly spent about 54 days in space service, and his younger brother Scott Kelly served 520 days. When the younger brother retired from a year-long mission in 2016, NASA found that the age gap between the two had widened.
In 2019,media reported that the Large Hadron Collider in Europe was able to hit protons at nearly the speed of light, causing its time to be 6,900 times slower than a human observer.
In a sense, these subatomic particles are actually sent to the future.
If you want to travel through time in a human body, you need a spacecraft that travels at the speed of light. For example, Popular Mechanics said, if you want to travel to the world 3000 years later, you only need to get on this light-speed spacecraft now, drive to a planet 500 light-years away from the earth, and come back. Although your journey only takes 10 years, the earth 1000 years have passed.
But these theory-based time travels are always about the future, not the past.
At present, it is still impossible to go back to the past. Perhaps with the deepening of human exploration of unknown fields and the gradual improvement of scientific standards, it is really possible for us to be able to create a real time machine, which can not only travel to The future can also go back to the past.
But until then, it’s better to spend every day without regrets.
