What is a smart factory? It is a shop floor that adopts smart manufacturing, manufacturing that uses technologies and solutions—like AI and IoT—arising from Industry 4.0 to optimize the production process…


Industrial revolutions then, and now

To fully grasp what smart factory is and where it’s headed, we must first understand the history of manufacturing.

It all began with the First Industrial Revolution, which introduced machines to factories and farms in the mid-18th century. In the past 250 or so years, manufacturing has evolved from handwork to machines like the spinning jenny, from the rise of machines to automobiles which were first introduced to the general public by Henry Ford in 1908, and from new inventions to digital technologies that made semiconductors, computers and the Internet possible.

Vice Prime Minister Fedorov reached out to Elon Musk for Starlink internet service in a last-ditch effort to restore internet access. As Russian forces approach Kyiv, Ukraine has been suffering internet problems.

Mykhailo Fedorov, Ukraine’s Vice Prime Minister and Minister of Digital Transformation contacted SpaceX CEO Elon Musk about the company’s Starlink satellite broadband service.

“While you are attempting to conquer Mars, Russia is attempting to invade Ukraine!” Fedorov said on Twitter. Russian missiles hit Ukrainian civilians as your rockets successfully land in orbit! We request that you send Starlink stations to Ukraine and direct all rational Russians to take a position.”

At the Vandenberg Space Force Base in California, SpaceX launched its second shipment of internet-bearing satellites on Friday. The satellites will deliver internet access to users all across the world.

Whether you live in an apartment downtown or in a detached house in the suburbs, if your mailbox is not built into your home you’ll have to go outside to see if anything’s there. But how do you prevent that dreadful feeling of disappointment when you find your mailbox empty? Well, we’re living in 2022, so today your mailbox is just another Thing to connect to the Internet of Things. And that’s exactly what [fhuable] did when he made a solar powered IoT mailbox.

The basic idea was to equip a mailbox with a camera and have it send over pictures of its contents. An ESP32-Cam module could do just that: with a 1,600 × 1,200 camera sensor, a 160 MHz CPU and an integrated WiFi adapter, [fhuable] just needed to write an Arduino sketch to have it take a picture every few hours and upload it to an FTP server.

But since running a long cable all the way from the house was not an attractive option, the whole module had to be completely wireless. [fhuable] decided to power it using a single 18,650 lithium ion cell, which gets topped up continuously thanks to a 1.5 W solar panel mounted on the roof of the mailbox. The other parts are housed in a 3D-printed enclosure that’s completely sealed to keep out moisture.

The new microbattery is roughly the size of a gain of dust – less than one square millimeter – and has a minimum energy density of 100 microwatt hours per square centimeter. To achieve this, the team winded up current collectors and electrode strips made of polymeric, metallic, and dielectric materials at the microscale. The researchers used Swiss-roll or micro-origami process.

The layered system with inherent tension is created by consecutively coating thin layers of polymeric, metallic, and dielectric materials onto a wafer surface. The mechanical tension is released by peeling off the thin layers, which then automatically snap back to roll up into a Swiss-Roll architecture to create a self-wound cylinder microbattery. The method is compatible with established chip manufacturing technologies and capable of producing high throughput microbatteries on a wafer surface.

The team behind the world’s smallest battery says it could be used in the human body, where tiny sensors and actuators require a continuous power supply. They also claim that the rechargeable microbatteries could also power the world’s smallest computer chips for about ten hours – for example, to measure the local ambient temperature continuously. In addition, it has great potential in future micro-and nanoelectronic sensorics and actuator technologies, in the Internet of Things, miniaturized medical implants, microrobotic systems, and ultra–flexible electronics.

The heat from Starlink’s receiver dishes is helping felines and other small animals stay warm through the cold winters.

Starlink is an important project of SpaceX and Elon Musk to provide high-speed satellite Internet to mankind. Although it is not yet clear how we humans will benefit, this project is definitely being extremely popular with cats, at least for the time being. The reason is because Starlink’s receiver dishes are becoming the ideal place for cats to rest and warm up in the cold winter.

Specifically, on a Twitter post on New Year’s Eve, one user named Aaron Taylor captured an image of 5 cats cuddled up on one of Starlink satellite dishes. Meanwhile, though the outdoor temperature seemed quite low and the ground was still covered with snow, the heat emitted from the receiver dishes appeared to be enough to warm the kittens, making them continue to lie there.
