World’s smallest computer is smaller than a grain of rice, powered by light

Gone are the days when computers were large, bulky pieces of machinery. Meet the Michigan Micro Mote, which has been deemed the world’s smallest computer.

At a time when computers are seemingly shrinking, the Michigan Micro Mote has taken the trend to a new level. To give you an idea of its size, the M^3 computer can fit seamlessly along the edge of a nickel. Its volume is about one millimeter cubed.

David Blaauw, computer science and engineering professor at the University of Michigan, worked with five students to create the device. Blaauw and his team were able to achieve the small size by taking the computer’s battery into consideration. By reducing the amount of power that it needed to work, they were able to minimize the battery and overall size of the computer.

The product has been under development for a decade. Because it does not use devices like a keyboard or a mouse, the developers were faced with the challenge of finding a new way for the computer to communicate. The M^3 was eventually designed to be programmed and charged with light.

When its operator strobes light at a high frequency, it can send information to the Micro Mote. Then, it can process the data and send it to a different computer through radio frequencies. The Phoenix processor inside of the compute requires just 500 pico-watts in standby mode, and it can charge its battery in a room with no natural sunlight.

Medical professionals are among the people who are already interested in the tiny computer, which is small enough to be injected in the body. The computer can take pictures, read temperatures and record pressure readings, which could provide benefit to the healthcare industry. However, the oil industry is also interested in the M^3. The idea would be to use the computer to detect pockets of oil that could be extracted before moving onto a new site.

As for the Michigan team, they think that the M^3 could prevent people from losing items, such as keys or wallets. The computers could be adhered to items that may get lost, and its central system could help users find items around the house.

Needless to say, tiny computers are in big demand these days. Both Google and Intel recently announced the development of computers-on-a-stick – devices meant to connect to televisions and monitors and temporarily turn them into working computers. However, the Chromebit and Intel Compute Stick aren’t necessarily garnering attention from the healthcare or oil industries. The M^3 is in an entirely different league of small, and proves that there’s still room for the tiny computer concept to grow.

AMD’s RDNA 4 may surprise us in more ways than one
AMD RX 7800 XT and RX 7700 XT graphics cards.

Thanks to all the leaks, I thought I knew what to expect with AMD's upcoming RDNA 4. It turns out I may have been wrong on more than one account.

The latest leaks reveal that AMD's upcoming best graphics card may not be called the RX 8800 XT, as most leakers predicted, but will instead be referred to as the  RX 9070 XT. In addition, the first leaked benchmark of the GPU gives us a glimpse into the kind of performance we can expect, which could turn out to be a bit of a letdown.

This futuristic mechanical keyboard will set you back an eye-watering $1,600
Hands typing on The Icebreaker keyboard.

I've complained plenty about how some of the best gaming keyboards are too expensive, from the Razer Black Widow V4 75% to the Wooting 80HE, but nothing comes remotely close to The Icebreaker. Announced nearly a year ago by Serene Industries, The Icebreaker is unlike any keyboard I've ever seen -- and it's priced accordingly at $1,600. Plus shipping, of course.

What could justify such an extravagant price? Aluminum, it turns out. The keyboard is constructed of one single block of 6061 aluminum in what Serene Industries calls an "unorthodox wedge form." As if that wasn't enough metal, the keycaps are also made of aluminum, and Serene says they include "about 800" micro-perforations that allow the LED backlight of the keyboard to shine through.

Google one-ups Microsoft by making chats easier to transfer
Google Spaces in Google Chat on a MacBook.

In a recent blog post, Google announced that it is making it easier for admins to migrate from Microsoft Teams to Google Chat to reduce downtime. Admins can easily do this within the Google Chat migration menu and connect to opposing Microsoft accounts to transfer Teams data.

Google gave step-by-step instructions for admins on how to transfer the messages. Admins need to connect to their Microsoft account and upload a CSV of the Teams from where they transfer the messages. From there, it requires just entering a starting date for messages to be migrated from Teams and clicking Star migration. Once it's complete, it'll make the migrated space, messages, and conversation data available to Google Workspace users.
