The popularity of mechanical keyboards surged from being a specialized item to becoming widely adopted during the epidemic as individuals sought to enhance their home workspaces and potentially explore a new pastime. Brands like Akko, Drop, Ducky, Epomaker, and Keychron have gained widespread recognition and are now well-known among enthusiasts. Today, these enthusiasts have a wide range of options when it comes to choosing alternative keyboard layouts and may purchase parts from numerous vendors.

Subsequently, the current situation has become somewhat uninteresting, as even the formerly exclusive capabilities have now become available on inexpensive keyboards. RGB lighting has become commonplace, as companies like Angry Miao and others consistently discover creative and novel applications for it. There is a vast array of switches to choose from, ranging from the lightest switches designed for games to the heaviest switches suitable for even the most enthusiastic typists. These switches come in linear, tactile, and clicky variations and are available in a seemingly limitless variety of colors. In the past, gasket-mounted keyboards, which provide a more cushioned and responsive typing experience, were mostly available on expensive keyboards for enthusiasts. However, nowadays, this feature has become commonplace across the board.

There are certain advantages to this situation: the overall construction quality of mechanical keyboards available on the market has reached unprecedented levels, and the prices have decreased. However, the entire situation has also grown quite monotonous. Magnetic switches are useful because they can rapidly alter the actuation point, which is the moment when the switch detects your downward keystroke.

In a typical mechanical keyboard switch, the act of pressing a key physically completes an electrical circuit, thereby registering the key press. When downward pressure is applied, the two legs on the stem, which is the movable component to which the keycap is connected, exert force on two metal leaves, resulting in the closure of the circuit.

The distinguishing factor between a linear switch, such as the Gateron Red switches commonly found on gaming keyboards, and a switch with a more tactile sensation, like the Cherry Brown switches, lies in the design of the stem and its legs. Linear switches include stems with a flat surface, whereas tactile switches contain a small bump that creates a moment of resistance when pressed down. The total configuration of the stem, including its legs, the spring, the base on which the stem rests, and the switch housing, can significantly influence the tactile and auditory feedback of a switch, as well as the precise moment at which the keyboard registers a keypress. In the case of a conventional Gateron Red switch, the keypress is officially recognized once you depress it by around 2 millimeters. The total distance the key travels before the stem reaches the bottom of the switch is 4 millimeters.

Mechanical switches exhibit significant dissimilarities. These devices are dependent on magnets and springs, and they operate by detecting changes in the magnetic field. These switches, popularized by the Dutch keyboard startup Wooting, utilize the Hall Effect and have been in existence since the 1960s. Although they retain the same fundamental construction as mechanical switches, including stems and springs, they lack the stem legs due to the absence of an electrical circuit that needs to be closed. Nonetheless, the stem has a permanent magnet, which allows the keyboard’s PCB sensor to accurately detect the switch’s position when pressure is applied. And this is where the most significant modification occurs: you have the ability to adjust the required depth for a keystroke to be registered.

During gaming, it may be desirable to capture finger movement as small as 0.1 millimeter. However, when using the same keyboard for typing, it is recommended to increase the threshold to 2.5 millimeters to prevent accidental keystrokes. Usually, this is accomplished by using a straightforward combination of keys on the keyboard or through the software tools provided by the vendor. Due to the sensitivity of these sensors to temperature fluctuations, there is usually an option available to calibrate the keyboard.

This feature also enables the implementation of more intelligent techniques, as it allows for not only modifying the location where the keypress is initiated but also where it is terminated. While typing, the responsiveness of the keyboard may not be of great significance to you. However, during gaming, it is crucial as it enables you to rapidly press a key when necessary. Magnetic keyboards often come with tools that have a rapid trigger setting, allowing you to quickly spam a key. Additionally, the extensive customization options of these keyboards allow you to experiment with different settings without the need to physically switch to a different switch.

If you desire to exceed the normal limits, you can create a macro-like function by assigning multiple actions to a single key. This allows for a different action to be registered when the key is pressed halfway down, when it is fully pressed down, and when the switch pushes the keycap back up. Additionally, you may assign another action to occur at some point in between these actions. Although I have not yet discovered a specific application for this in my own life, it is highly likely that someone else will.

However, the resistance of the switch is immutable and cannot be altered. Despite the extensive discussion of magnets, the spring inside the switch is ultimately responsible for performing the function.

An issue arises from the lack of a standardized format for these switches, resulting in the incompatibility of some switches with specific keyboards. Depending on the manufacturer, it is possible to connect traditional mechanical switches to the PCB as well. However, it is important to note that these switches do not offer the same customizable advantages as magnetic switches.

A journey to Santorini: Akko’s MOD 007B personal computer
In order to evaluate the product, Akko provided me with a review unit of their MOD007B PC Santorini keyboard. This keyboard belongs to the World Tour series and is characterized by its more understated design compared to other models in the series. The gasket-mount MOD007B PC is available at a price of approximately $150, but it is commonly sold for roughly $110 on Amazon. This keyboard comes pre-assembled and features Kailh’s linear Sakura Pink magnetic switches. The PCB is compatible with 3-pin mechanical switches.

Connectivity options include normal Bluetooth and USB-C connections, as well as a multi-host 2.4Ghz option that requires the provided dongle. The board is equipped with a 3600mAh battery to support wireless operations.

The 75-percent case is not very remarkable since it is made of simple polycarbonate. However, unlike many high-end keyboards, it has the ability to modify the typing angle using its dual-position feet.

Akko employed a sufficient quantity of foam within the case to modulate the sound of the board, resulting in a clacky auditory experience. I have a taste for a sound that is slightly more muted, although I acknowledge that this is entirely subjective. The stabilizers are finely calibrated, but there is a discernible level of case ping. A few minor modifications should address that issue. However, it is noteworthy that this board’s most apparent drawback remains unaddressed, despite the firm producing numerous generations of MOD007 boards. A few minor adjustments should resolve the issue, but purchasers should not be required to make such improvements even at this price range.

Regarding the software, Akko has developed its own exclusive software tool that is capable and user-friendly. It fulfills its intended purpose and does not interfere with your activities. One drawback of boards using magnetic switches is their tendency to prioritize proprietary software over open-source alternatives such as VIA.

The focus of this board is solely on magnetic switches. I derived considerable pleasure from doing experiments with them, and although I did not emerge victorious in obtaining a single chicken supper in PUBG throughout the testing phase, I did perceive that, at the appropriate configuration, it enabled me to respond with a slightly enhanced speed. The level of success you experience with Valorant and other shooters may differ, as the effectiveness of rapid trigger functions can play a significant role. Regardless, it is an enjoyable board game to play.

The switch is a Khailh Sakura Pink magnetic switch with a bottom-out force of 50 gf. That aligns with the characteristics of typical linear switches, but it may be slightly heavier than average.

It took me some time to discover the optimal configuration for everyday typing. After trying out several options, I ultimately settled on Akko’s default comfort setting, which establishes the actuation and release points at a precise measurement of 2mm. The default game setting is set to a speed of 0.5mm, which appears to be sufficiently quick.

Although not the most high-end board available, Akko has developed a keyboard that, when adjusted correctly and with a few small modifications, offers a satisfying typing experience (if you prefer linear switches) and also serves as a suitable gaming platform. The crucial aspect here is that this board enables both gamers and non-gamers to enter the magnetic switch market without incurring significant additional costs. Is it the most superior board available? Although it is not significantly better, considering the price, it is difficult to find a better option.

Supercapacitors Reach New Heights with 19 Times Greater Capacitance

Based on papers published at the same time by unrelated teams, two methods for improving capacitors’ ability to store charge appear to be effective. Each has the potential to make supercapacitors better at storing energy and maybe even put them in the running for large-scale energy storage.

For a long time, supercapacitors have been better than batteries because they can quickly release the charge they have stored. But not even the best supercapacitors have been able to store enough power to meet the most important needs of society. Sometimes, big steps forward have made supercapacitors look like they could compete in that market. But since lithium-ion battery prices have dropped so much, there isn’t much room for other batteries. That could change soon.

Two papers that came out last month in the same issue of Science both look at big improvements in capacitance. It remains to be seen if either of them can be scaled up, though.

The basic idea behind all capacitors is the same. There is material between the positive and negative charges to keep them from jumping across the gap. When a switch is closed, the negative charges can move around to meet the positive charges. This makes an electric current, which can be used for many things.

Laptops and phones now have hundreds of capacitors inside them. When you look at a phone, you can tell how small it is. Because of this, the amount of power they can store is many times too small to power a car, let alone a city all night.

As you might guess from their name, supercapacitors have a lot more capacitance. Even though they’ve made regenerative braking possible, batteries are still the best choice for long-distance driving. To make that happen, the capacitance has to go up, which means finding cheap materials that stop very large amounts of charge from recombining.

Many capacitors use ferroelectric materials like BaTiO3, but they have a problem called “remnant polarization,” which means that some charge stays behind instead of being released. Their crystals also break down over time.

A team from Korean and American institutions reduced remnant polarization by putting a 3D structure between 2D crystals. They were then able to store 191.7 joules per cubic centimeter of capacitor and release it with more than 90% efficiency. Similar products on the market today can store around 10 joules per cubic centimeter.

Dr. Sang-Hoon Bae of Washington University in St. Louis said in a statement, “We made a new structure based on the innovations we’ve already made in my lab involving 2D materials.” “At first, we weren’t interested in energy storage, but while we were studying the properties of materials, we came across a new physical phenomenon that we thought could be used for energy storage. It was very interesting and could be much more useful.”

The work report by Bae and his co-authors only talks about testing the capacitor over 10 cycles, which shows that there is still a long way to go before it can be used in real life. “We’re not quite at our best yet, but we’re already doing better than other labs,” Bae said. For capacitors to be able to charge and discharge very quickly and hold a lot of energy, our next step is to improve the structure of this material even more. To see this material used widely in big electronics like electric cars and other new green technologies, we need to be able to do that without losing storage space over time.

In the same issue of Science, scientists from Cambridge University talk about results that change how people think about making supercapacitors with carbon electrodes store more power. They say, “Pore size has long been thought to be the main way to improve capacitance.” But when commercial carbons with pores measuring nanometers were compared, there wasn’t much of a link between size and capacitance. With nuclear magnetic resonance spectroscopy, we can see that what matters is the level of structural disorder in the capacitors’ domains.

They say that more disorganized carbons with smaller graphene-like domains have higher capacitances because their nanopores store ions more efficiently. “We think that for carbons with smaller domains, the charges are more concentrated, making the interactions between ions and carbon atoms stronger. This makes it easier for ions to be stored.”

The paper makes no mention of how much capacitance is possible when the carbon domains are sufficiently disorganized. This is because it goes against the norm to try to make electronic devices more disorganized than ordered.

As AI comes out, Google adds a “Web” search filter that shows old-school text links

Google is undergoing a transformation to adapt to the AI era. As part of this, the company is now providing AI summaries directly in its search results. Additionally, Google is introducing a new feature that allows users to filter their search results to only display text-based links. The addition of the new “Web” filter at the top of the results page will allow users to specifically filter for text links, similar to how they can currently filter for images, video, news, or shopping.

The announcement was made on Tuesday through a post on X during Google I/O, the company’s developer conference. During the conference, Google introduced significant changes to its search engine, including AI-organized search results and AI overviews in search.

Google states that the new “Web” filter will be visible either at the top of the results page or within the “More” option, depending on the specific search query.

The launch acknowledges that there are instances when individuals simply desire to display text-based links to web pages, which are typically considered less significant nowadays as Google either provides answers directly in its informational Knowledge Panels or, more recently, through AI experiments.

The Google SearchLiaison X account is noted. The post stated that this addition was made in response to feedback from users who expressed a preference for seeing only web page links in their search results. This preference may arise when users are searching for longer-form text documents, using devices with limited internet access, or simply preferring text-based results to be displayed separately from search features. “If you belong to that particular group, I hope you have a pleasant experience!”

Google has specified that on mobile devices, the new “Web” filter will be displayed by default, along with the other filters, without necessitating users to access the “More” menu. On desktop, Google will display the filters that appear to be the most pertinent to the search results.

Google announced that the feature will be gradually released to users worldwide over the course of today and tomorrow.

The announcement of a “Web” filter is bound to spark some controversy, especially among the SEO community. These experts have always strived to enhance their links in order to secure a spot on the first page of Google search results for specific keywords. However, this type of SEO manipulation has potentially diminished the usefulness of Google compared to its early days. At that time, search experts weren’t manipulating the PageRank algorithm.

The move is a significant gamble that suggests the future of search may not revolve around presenting website links. Instead, users may find the answers they are looking for in alternative forms of content or even AI responses that provide sources for those who want to explore the topic in more depth. It is yet to be determined how these changes will impact industries that heavily depend on clicks and visitors.

Threads finally starts its own program to check facts

Meta’s latest social network, Threads, is launching its own fact-checking initiative after leveraging Instagram and Facebook’s networks for a brief period.

Adam Mosseri, the CEO of Instagram, stated that the company has recently implemented a feature that allows fact-checkers to assess and label false content on threads. Nevertheless, Mosseri refrained from providing specific information regarding the exact timing of the program’s implementation and whether it was restricted to certain geographical regions.

The fact-checking partners for Threads—which organizations are affiliated with Meta—are not clearly specified. We have requested additional information from the company and will revise the story accordingly upon receiving a response.

The upcoming U.S. elections appear to be the main driving force behind the decision. India is currently in the midst of its general elections. However, it is improbable that a social network would implement a fact-checking program specifically during an election cycle rather than initiating the project prior to the elections.

In December, Meta announced its intention to implement the fact-checking program on Threads.

“At present, we align the fact-check ratings from Facebook or Instagram with Threads. However, our objective is to empower fact-checking partners to evaluate and assign ratings to misinformation on the application,” Mosseri stated in a post during that period.
