By adding these incredible touches, Gehrer doesn’t simply make the Watch better, he converts it into a miniature iPhone, which is something Apple has done before, by converting the iPad into a mini MacBook!
3. Apple-Inspired Alarm Clock
This Apple-inspired alarm clock features a big flat button on top it, which lets you snooze the alarm, and extend your sleep, without waking you up entirely from your slumbering state. You can hit the button even with your eyes closed, which is the aim behind the design. The design of the alarm clock is pretty streamlined since it has a focused purpose. It features Apple’s famous minimalist design language and is essentially a small cube with a small LCD screen on the front, and a USB-C charging port on the back, with Apple’s logo on the top.
4. iPhone Fold

Nathan’s modern iPhone 4 features two massive camera lenses which softly protrude out from the flat surface of the phone. It is equipped with a Dynamic Island on the front, and a USB-C on the bottom. But unlike the OG iPhone 4, this one doesn’t have a Home button or any other button for that matter. However, it does have a flush control surface and a mute switch.
6. MacBook Go
Meet the MacBook Go – a MacBook without a screen! The MacBook Go is the complete opposite of the iMac – it is basically all keyboard. Featuring its own DLP projector, this all-in-one keyboard has everything you need to work anywhere anytime. You just need to find an empty wall, pair a Magic Mouse, and you’re all set to get working. It is a keyboard-shaped device, but it functions as a full-fledged computer. How cool is that?! You don’t need spatial computing with a keyboard that serves as an entire computer system.
7. Magic Mouse Touch
Reid Parsekian tweaked and elevated the Magic Mouse, imparting it with a cool new feature! This revamped Magic Mouse features a sprawling curved display on the top. He combines the Touch Bar with the Magic Mouse to create a device that is more user-friendly, functional, and appealing to Apple’s hardcore audience. This “Magic Mouse Touch” is designed to be an external display, something you never thought you would need but will probably want now. It serves as a better mouse too!
8. Apple Car Concept
This mesmerizing Apple Car was created by Dall-E 2 based on a text prompt from the designer, educator, and YouTuber John Mauriello. The incredible-looking car is really quite unique, and is intended to be a ‘minimalist Sportscar inspired by a Macbook and a Magic Mouse, built out of aluminum and glass’. It features a sleek and curvilinear quality and is a complete looker. The car is amped with a machine aluminum body, and zero breaks on the surface.
9. All-Screen Apple MacBook Concept
Meet the All-Screen Apple MacBook concept! This design is a whole other kind of MacBook, one that we haven’t seen before. It supports TouchID (as a slide button), a trimmed version of FaceID, as well as an AirPen to doodle and write on the massive screen. The display is entirely foldable, and it doesn’t have a physical keyboard, but it does feature a digital keyboard with haptic feedback for the real typing experience. This unique device will have dual usage – it could serve as an iPad when folded, and a full-fledged laptop when open.
10. Apple Watch Series X
Dubbed the Apple Watch Series X, this super cool and interesting conceptual design is an innovative smartwatch with a large folding screen. This allows you to use the watch as a de-facto iPhone! The Apple Watch Series X is like other regular foldable on the market since it features a primary screen on the front, which can be gently opened like a book to reveal a ‘larger’ secondary screen on the inside, serving as a smartwatch and a smartphone.
Microsoft killed its foldable smartphone adventure in 2023 after two iterations of its unique idea of a folding phone. The Surface Duo and Duo 2’s two-screen design didn’t pan out too well with the consumers. While the competition in the foldable Android phone market perfected the creaseless form factor, Microsoft – though having outsmarted Apple to the foldable phone category – lost out with its unprogressive design.
A new patent shared by Patently Apple shows that Microsoft, most likely, had made peace with the demanded form factor and may have been working on a design codenamed Neon (supposedly the now-canceled Surface Duo 3). The unreleased device detailed in the patent, shows how the phone would have looked with improvements like an external cover display, single folding screen without a crease, and Apple MagSafe-esque magnetic accessories.
The uncanny two high-resolution touchscreens of the Surface Duo 2 couldn’t open the users’ minds to adoption and Microsoft felt the pinch of it. A reason why the patent of a never-released phone suggests that the device was being visioned with a concealed hinge folding inner display – like in Galaxy Fold models – instead of two separate displays with a noticeable distinguishing hinge.
The new 180-degree hinge design of the device, in the patent, is accompanied by a cover screen on the outside, which was missing in the previous surface models. Interestingly, the design suggests the cover and inner folding screens with edge-to-edge, and a camera in the cover display for selfies and video calling. A larger camera array on the back – spanning the entire width of the device – features a triple camera module that looks identical to the iPhone’s camera array with lenses placed on the top left-hand side.
A standout feature revealed in the patent is support for magnetic accessories. This is an Apple MagSafe-style feature, which shows a kickstand attached to the device to prove its functionality and usability in different orientations. Additionally, the foldable phone featured a power button updated to pop open the phone – like a book – on a press, saving the user the effort of manually opening the two halves of the device. I know, Microsoft is not going to release a folding phone based on this revealed patent anytime in the future, but I think it did have the mettle to compete I presume.

Wireless connectivity has become an invisible thread woven into the fabric of our daily lives. From streaming music to our earbuds to connecting keyboards and printers, Bluetooth technology has replaced a tangle of wires with seamless, invisible magic. Sure, we all lamented the day Apple killed the headphone jack (it’s been 8 long years since that day), but try and imagine a life without Bluetooth. Wires wires everywhere, data cables to transfer files between machines, and requiring to load all your songs on USB drives to play on your car stereo or home theater. Sounds like a pretty awful life, doesn’t it?? But how exactly does this magical thing called Bluetooth work? Let’s take a closer look at the fascinating world of wireless Bluetooth communication and explore the science behind its seemingly effortless operation.
Bluetooth’s roots trace back to 1994, when Ericsson’s Jaap Haartsen aimed to create a short-range wireless connection for mobile phones, booming in popularity at the time. This technology, using low-power UHF radio waves, would eliminate the need for bulky cables. The name, inspired by 10th-century Viking king Harald Bluetooth, aimed to reflect how the technology would unite devices like those once-warring kingdoms. The Bluetooth Special Interest Group, formed in 1998 by Ericsson, IBM, Intel, Nokia, and Toshiba, ensured standardization and widespread adoption.
Bluetooth utilizes radio waves for communication, but unlike the visible light we perceive, it operates on a specific and invisible range of the electromagnetic spectrum. This range falls between 121mm and 124mm in wavelength, significantly longer than the radio waves used for Wi-Fi. This longer wavelength allows Bluetooth signals to pass through walls, making it suitable for short-range data transfer within a room or a few meters.
The magic of transforming these radio waves into music or data streams lies in a clever manipulation of their properties. Bluetooth transmits information by altering the radio waves themselves. To send a binary 1, the Bluetooth antenna emits a specific radio wave with a particular wavelength. Conversely, to send a 0, it transmits a different wavelength within the designated range. This seemingly simple approach allows for incredibly rapid data transmission. In fact, Bluetooth can send and receive information at a million times per second, ensuring smooth audio streaming or data transfer without any noticeable lag.
But with so many Bluetooth devices around us, how do our earbuds differentiate between our phone’s signal and everyone else’s in a crowded space? This is where Bluetooth’s genius truly shines. It doesn’t rely on a single channel for communication. Within the designated wavelength range, there are actually 79 individual channels available. To avoid interference and ensure smooth communication, Bluetooth devices constantly hop between these channels at a staggering rate of 1,600 times per second. Imagine a crowded room filled with people having multiple conversations simultaneously, each conversation happening on a different frequency – that’s the essence of how Bluetooth avoids interference and ensures clear communication even in environments saturated with Bluetooth signals.
An additional layer of security is implemented through a process called pairing. When you connect your phone to your earbuds for the first time, they exchange a unique encryption key. This key acts like a secret handshake between the two devices. Only the phone’s signal with the matching encryption key can be decrypted by your earbuds. Even if someone intercepts the data stream being transmitted via Bluetooth, they wouldn’t be able to decipher it without the specific key, protecting the privacy of your communication.
But what if multiple devices in close proximity try to use the same channel at the same time? This is where Bluetooth prioritizes established connections. Your earbuds will recognize your phone’s unique encryption key and prioritize its signal, effectively filtering out unwanted audio or data from nearby devices attempting to connect. This ensures a clear and uninterrupted connection, even in crowded environments.
Beyond music streaming and connecting peripherals, Bluetooth continues to evolve and expand its capabilities. Bluetooth Low Energy (BLE) is a newer iteration of the technology specifically designed for internet-of-things (IoT) applications. BLE offers lower power consumption compared to traditional Bluetooth, making it ideal for battery-powered devices like smartwatches and fitness trackers. Additionally, advancements in Bluetooth technology have led to the development of Bluetooth mesh networks, which enable a network of devices to communicate with each other, opening doors for innovative applications in smart homes and industrial automation.
So next time you lose yourself in music with your wireless earbuds, take a moment to appreciate the invisible symphony of radio waves, hopping frequencies, and clever encryption that keeps the magic of Bluetooth alive. It’s truly a marvel of science and a major pat on the back for the engineers who have harnessed the invisible forces of the electromagnetic spectrum and transformed them into a ubiquitous technology that shapes the way we interact with our devices and the world around us. After all, we wouldn’t want to be stuck in the dark ages of the 2000s with infrared-based data-transfer capabilities… do you remember those times?!
Just when everyone is leveraging the power of artificial intelligence (AI), why should avid LEGO fans not dig a share in the pie? Dutch creator, YouTuber, and master brick builder Sten, thought of the obvious and set out to harness the power of AI and built a printing machine entirely from LEGOs that can print any subject into identical pixel art.
The entire building process, along with a demo pixel art made from LEGO pieces, has been documented by Sten on his YouTube channel, Creative Mindstorms. The Pixelbot 3000, as the LEGO printer is called, Sten informs, is ‘capable of creating pixel art of anything using AI.’
The Pixelbot 3000 is programmed in Python using help from DALL-E from OpenAI. Sten has managed to program, and create software-hardware integration, in such a manner that you simply ‘type a subject line, hit start’ and the printer takes on from there.
Sten informs, in the video, that he started with inspiration from LEGO printers such as Briccasso, but over time had to improvise a great deal – both with the code customization and the machine functionality – to achieve what he set out to build. He initially used 16 x 16 base plates to print the developed pixel art, but it was later changed to a 32 x 32 grid for better result output.
The basic operation of Sten’s LEGO machine is similar to that of a pick-and-place machine, which has been precisely programmed and created to place large-size LEGO pieces with surprising accuracy on the 32 x 32 grid base plate. Moreover, the machine is designed to pick colors – according to the picture’s demand – and place brick-by-brick to achieve the identical pixel art of an AI image generated. Since LEGO brick colors are limited, Creative Mindstorms reduced its machine’s color palette to 15 base colors including a white background.
The machine does not at any point rely on designing the art or scanning it. It instead uses AI to generate pixel art (using LEGOs) of the image generated in the software. The user can preview the generated image, crop and color grade it, before saving it for printing. When commanded for print, the image is divided into 32 x 32 grid, color and center of each pixel on the base plate is sampled, and the pixel art is then built piece by piece. In the testing, Sten asked AI to create a ‘quirky robot holding a sunflower,’ you can check out how it came out in the video above.
