Nothing beats a skylight when it comes to brightening up a gloomy living space, but installing one can be a pricey proposition. At CES, smart light manufacturer Govee is showing off an alternative: a smart ceiling light that mimics daylight.  The Govee Sky Ceiling Light employs “custom-engineered LED and architectural gradient illumination” to serve up “clear-sky tones and soft skylight transitions,” ideal for casting some simulated daylight into a gloomy, windowless living area.  The light boasts a total of 180 RGBICWW beads—84 for the main circular panel, 60 on the side, and 36 in back—that combine to shine at up to 5,000 lumens at a daylight-equivalent 6,500 Kelvin color temperature, according to Govee. If you’re looking for more of a golden glow in the morning, the light’s color temperature can be dialed all the way down to a warm 2,700K.  The 21 x 4.3-inch (WxH) ceiling light (we don’t have pricing details or a release date yet) uses wired power, so you’ll need to connect it to in-ceiling wiring; otherwise, it should be relatively easy to install.   The Sky Ceiling Light can be controlled with the Govee app, which offers dozens of animated lighting scenes along with smart automations and wake-up/go-to-sleep routines. We’ve reached out to Govee for specifics on integrations with other smart home platforms, such as Alexa, Google Home, and Matter support.  Govee is also unwrapping a couple of other new smart lights at CES this week, including a second ceiling light with a 616-pixel LED matrix that delivers “vivid patterns and animations,” Govee says.  The Ceiling Light Ultra is the same size as the Govee sky light and also shines at up to 5,000 lumens at a daylight-equivalent 6,500K, but this ceiling light is more focused on groovy animations courtesy of Govee’s AI Lighting Bot 2.0, the brand’s updated generative-AI lighting tech that’s designed to “instantly” create “expressive” and “animated” effects.   Govee As with the Sky Ceiling Light, the Ceiling Light Ultra relies on wired power and works with the Govee mobile app.  Finally, the Govee Floor Lamp 3 is a revamped version of Govee’s previous floor lamps, and it arrives with another new Govee technology: LuminBlend+, a color management system with an upgraded 16-bit chip for “smoother, more precise color transitions,” according to Govee.  The Floor Lamp 2 also works with Govee’s AI Lighting Bot 2.0 as well as DaySync, an adaptive lighting technology that automatically adjusts the lamp’s color temperature and brightness according to the time of day.  Govee The 59 inch-tall Floor Lamp 2 can shine at up to 1,900 lumens and has an exceptionally wide color temperature range, all the way from 10,000K (producing a cool, bluish light) to 1,000K (for a very warm reddish-orange color). Aside from Govee app control, the lamp can also be adjusted with the included remote.  Aside from its new smart lights, Govee is also announcing a partnership with Samsung SmartThings, allowing for “seamless” integration between the SmartThings ecosystem and “key” Govee smart lighting products. We’re awaiting details on the first Govee lights to offer SmartThings support. Matter-enabled Govee lights can already work with SmartThings, along with Alexa, Apple HomeKit, Google Home, and other smart platforms that connect via Matter. This story is part of TechHive’s in-depth coverage of the best smart lights. Read...

Mounting a jumbo-sized, multi-panel TV on a wall is no small feat, as you’ll need mounts for the individual panels, in-wall wiring to connect the components together, one or more videos controllers to feed images to the TVs, and possibly even a fake wall to hide all the cable clutter.  At CES this week (where it will also be showing off its next-generation wireless TV line, first unveiled in December 2022), Displace is promising to drastically chop the time and effort needed to install a massive TV array, with the 4K OLED Displace Wall designed to be mounted in just half an hour and without the need for any drills or wiring-hiding facades.  Arriving in two sizes—a 110-inch 4K display comprised of four 55-inch displays, and a 130-inch version with a quartet of 65-inch panels—the Displace Wall arrives with a custom frame that employs “active-loop” suction technology, meaning you can simply stick it to the wall.   Displace Aside from not needing extra mounting hardware, the Displace Wall also dispenses with external video controllers, with each panel incorporating the necessary video wall functionality while a single “host TV” in the array acts as the primary connection point for the other panels.  For power, the Displace Wall relies on a removable 10,000 mAh/46.8-volt battery, meaning no need for power cables. How long will the battery keep the Display Wall running? Good question; we’ve reached out to Displace for more details.  Powered by Displace OS 2.0, an “ambient computing”-focused platform that turns each 1.26-inch thick panel into a “smart, responsive surface,” the Display Wall can display a single, jumbo-sized video images or four separate video feeds, according to Displace. You can also expand a video on one TV to the others with a simple gesture.  From a technical standpoint, the Displace Wall runs on a 8-core Intel N-300 CPU with integrated graphics, 32GB of RAM and 256GB of storage, while the panels themselves are capable of up to 40K resolution at 30Hz. The Wall can run completely wirelessly, but there’s also an HDMI port on the host TV for connecting external HDMI-enabled video sources.  Before you get too excited by the stick-up Displace Wall, consider the price: $39,999 for the 110-inch version or a whopping $59,999 for the 130-inch model. At those price points, the Displace Wall is more likely to wind up at trade shows and corporate lobbies rather than living rooms. The company’s existing 55-inch OLED sells for $5,999. If you find Displace TV’s unique wall-mounting and truly wireless technologies appealing, the manufacturer will also be showing a module that can retrofit existing TVs with screen sizes between 55- and 100 inches and weighing up to 150 pounds. Displace TV has not announced pricing for that product. Read...

At a glanceExpert`s Rating Pros Rapid response times and customizable trigger paths Clear, flexible software 8.000 Hz polling rate for minimal latency. Smooth, pre-lubricated switches, and good housing insulation Hot-swappable PCB Housing made from 65 percent recycled plastic Cons High price Mediocre casing finish in places Rattling space bar Silicone feet are inflexible and prone to dust Our Verdict The Wooting 80HE, with its analogue keys, Rapid Trigger, and 8,000 Hz polling rate, is a high-end mechanical gaming keyboard designed for FPS gamers who love to tinker. Price When Reviewed This value will show the geolocated pricing text for product undefined Best Pricing Today Best Prices Today: Wooting 80HE Retailer Price Check Price comparison from over 24,000 stores worldwide Product Price Price comparison from Backmarket Best Prices Today: Check today’s prices When a keyboard is hailed as the holy grail of competitive gaming, it deserves a closer look. The Wooting 80HE’s reputation precedes it. More than just an input device, its state-of-the-art technology gives you a real advantage in shooters like Counter-Strike 2 or Valorant. We put the highly coveted 80 percent gaming keyboard through its paces. Along the way, we examine whether its innovative analogue technology justifies the steep price tag of around $199.99, and if its recycled plastic housing lives up to the standards of a premium product. Wooting 80HE: Design and construction Even unpacking the Wooting 80HE is fundamentally different from dealing with conventional manufacturers. The company consistently focuses on modularity and sustainability, which means that you can build it yourself. The keyboard base and keycaps are supplied separately in some cases, so you first have to fit the high-quality PBT keycaps to the switches yourself. Although this takes a few minutes, it immediately gives you a deep understanding of the device and emphasizes the “DIY charm” of the brand. Friedrich Stiemer Our test model comes in a black casing made of PCR plastic. PCR stands for “Post-Consumer Recycled,” meaning the chassis is largely made of recycled plastic. This is good for the environment, but it does have some disadvantages in terms of feel. The Wooting 80HE appears robust at first glance, but the plastic housing does show a certain amount of give under heavy pressure, especially above the space bar. The material can be noticeably pressed in and occasionally responds with a quiet creaking noise. Anyone expecting the absolute rigidity of an aluminum block will either have to adjust their expectations or dig deep into their pockets and purchase the optional metal casing. Friedrich Stiemer The manufacturer also goes its own way when it comes to ergonomics. Instead of relying on classic folding feet for height adjustment, the keyboard comes with various silicone pads. These pads are attached to the underside without tools to adjust the angle of inclination to 2.8, 6, or 10 degrees. Although this solution ensures a non-slip stand, it’s impractical in everyday use. The rubber feet attract dust almost magically and can come loose if you frequently move the keyboard around on your desk. Friedrich Stiemer Wooting 80HE: Technology and features The real highlight of the Wooting 80HE lies hidden under the keycaps. No classic mechanical contacts are used here, which only have an “on” or “off” function. Instead, Wooting uses Lekker V2 magnetic Hall-effect switches. This allows the keyboard to measure exactly how deep a key is pressed, which is anywhere from 0.1 to 4.0 millimeters. Friedrich Stiemer This analogue recording enables functions that make conventional gaming keyboards feel outdated. The most important feature for gamers is undoubtedly “Rapid Trigger.” Unlike normal switches, which first have to pass a fixed point before resetting, the Wooting 80HE’s reset point adapts dynamically. As soon as you lift your finger, the signal is interrupted. If you press it down again, it’s immediately triggered again. The result is an extremely fast reaction time, which can offer a noticeable advantage in terms of precision, especially during fast sideways movements in shooters (known as strafing). Friedrich Stiemer In addition to top-tier performance, the analogue technology also allows controller-like control. In racing games, for example, you can fine-tune the throttle and steering depending on how deeply you press the buttons. This technology is supported by an extremely high polling rate of 8,000 Hz. This means that the Wooting 80HE reports its status back to the PC 8,000 times per second. Even if this difference to conventional 1,000 Hz keyboards is barely perceptible to the average gamer, it gives professionals the reassuring feeling that the hardware isn’t a technical bottleneck. Keep in mind, however, that a cable connection is absolutely necessary for this speed. You’ll have to do without wireless features such as Bluetooth or 2.4 GHz radio. Friedrich Stiemer Wooting 80HE: Software Wooting’s “Wootility” software manages all these complex features in an exemplary manner. A big advantage here is that you don’t have to download an installation file if you don’t want to. The tool runs entirely as a web app directly in the browser and is available for Windows, Mac, and Linux across platforms. Friedrich Stiemer You can configure the trigger point for each individual button on the Wooting 80HE through its clearly organized interface. Whether you want the WASD keys to react the instant you touch them or the space bar to trigger only when fully pressed, the choice is entirely yours. RGB lighting and key assignments are also controlled here, stored directly in one of the keyboard’s four internal memory profiles. Although Wooting offers advanced scripting functions for perfect “counter-punishing” (known as “Snappy Tappy” or SOCD), you should exercise caution here. Game developers such as Valve have begun to block such automated input aids in titles like Counter-Strike 2. However, the core functions like rapid trigger and analogue triggering remain unaffected and continue to be legal competitive advantages. Friedrich Stiemer Wooting 80HE: Typing feel and gaming performance In everyday use, the Wooting 80HE shows two faces. When simply typing, it surprises with a very pleasant feel. The Lekker switches are well lubricated, gliding smoothly without scratchy feedback. Thanks to several layers of insulation in the casing, the acoustics are rich and comparatively quiet, which makes it perfectly suitable for office use. However, there is one acoustic outlier: the space bar. Compared to the other keys, it sounds much hollow, loud, and can rattle. Given the price, this is annoying, although experienced users can improve this themselves with a little grease on the stabilizers. Friedrich Stiemer When you switch from a word processing program to a game, the keyboard really comes into its own. In our gaming test, controlling the game character felt incredibly direct and instantaneous. Stopping and shooting happens at the exact moment the thought reaches your finger. It’s difficult to describe, but anyone who has experienced Rapid Trigger on the Wooting 80HE often finds conventional mechanical keyboards sluggish in comparison. The keyboard almost gives the feeling of artificially shortening your own reaction time. For competitive players who want to get the most out of their gaming, this feedback is worth its weight in gold. Friedrich Stiemer Read...

I don’t typically make New Year’s resolutions, but 2026 is a special exception. You can thank stratospheric memory prices for that—and a little scare that happened right before Christmas. Micro Center briefly marked a handful of SSDs for sale at their suggested list price, alarming DIY PC builders with the thought of $600+ 2TB NVMe drives. I lived a few potential lifetimes in the short period before Micro Center restored its real prices. That is, I imagined several possible paths for what I’d do if I couldn’t afford PC building. More specifically: What I would have fun doing. Being a hardware enthusiast is more than just devotion to the hobby, in my book. It involves a certain perspective about technology overall—a deep appreciation and interest in what those things can do at full blast. Limiting myself to focusing only on new PC parts cuts out so much of what I could dive into.  So I thought awhile on what “full blast” would mean for me in 2026, a likely year of building drought. I narrowed it to two main angles: What hobbies adjacent to PC building have I let languish or neglected? Could I find new or alternative uses for the hardware I already have? Then I thought about what gets my attention, and in what ways. Mechanical keyboards and elaborate homebrew NAS setups would be too expensive for me to pick up as building hobbies…but not as areas for greater learning. Nothing’s stopping me from plunging down the rabbit hole of deeply absorbing the ins and outs without any hands-on time. And if I need a more immediate project, I could finally sit down with both Jellyfin and Plex, as well as my media collection, and finally properly rip everything for local streaming. As I’ve intended to do for literal years now. (Yeah…) Maybe it’s time to roll my own homebrew version of one of these lil’ guys.Foundry But I’ll confess, I’d find tinkering with my existing hardware much more interesting than diving into media software. I have so much of it on hand already, and in true proto-hoarder fashion, I’m reluctant to give it up. Especially when I don’t know if I could afford to replace it. Especially when 2026 will likely be another Year of Linux. So here are my resolutions, in order of firm plans: Start at least one Linux project. (I say start because I don’t know if success is possible for my initial goal: To convert my old beloved Chromebook at last.) Use at least one or two distros for a few months. Expand my knowledge in areas I know less or even nothing about. Networking is currently a top contender. So is rolling my own NAS with old parts and old drives, just to see how I’d like it. Attempt a repurposing that isn’t typical for the hardware. (For example: Repurposing an Android-based E-Ink tablet as a second screen.) If successful with Resolution #1, attempt to convert remaining applicable hardware to Linux. If 2026’s theme is “We have ____ at home,” then you know what? I’m going to try to enjoy the experience. We touched on this idea briefly at the end of our final TFN episode of the year, when we finished making all of our 2026 predictions. All the time I would normally spend on new technology, I can repurpose to becoming smarter and savvier about existing technology. I find that pretty exciting still.

Each new CES is an opportunity for a glimpse at the processors and platforms coming for the new year, even if they have been previously announced. This year is no different. Two of the three major arrivals have already been disclosed, both for notebooks. Intel has revealed its next-generation Core Ultra platform, “Panther Lake,” and Qualcomm has announced that its next-generation mobile Windows on Arm processor will be the Snapdragon Elite X2. Only AMD has yet to reveal what its upcoming chip for laptops will be, though its customers published a projected roadmap some months ago. But what’s happening with desktop PCs? And could Nvidia have something up its sleeves for the big show? Right now, it’s impossible to know what PC makers are going to announce at CES 2026. Still, we can make some guesses. Here’s what we expect may be revealed by Intel, Qualcomm, AMD, and Nvidia. Intel: It’s all about Panther Lake Clearly, Intel will launch its Panther Lake (Core Ultra 300) processors at CES 2026. Intel has already revealed some of the deep-dive details of the Panther Lake architecture: a return to the efficiency and low-power efficiency cores as well as the performance cores alongside the Xe3 graphics core and an upgraded NPU. Normally, we stop there and begin wondering about clock speeds and pricing. But wait! Intel really has three designs to think about: an 8-core and a 16-core chip, and than a version of the 16-core chip with 12 Xe3 graphics cores inside it. Naturally, we’d assume the 12-Xe version would be the premium offering, but will PC vendors consider this version as a challenger to the AMD Ryzen Max? I tend to doubt it, but it’s possible. Intel Intel still has a stranglehold on the laptop market. Its previous chip, the Core Ultra 200, was excellent, offering a potent mix of long battery life and decent computing power. Typically Intel gives us a chance to do a little benchmarking at the show, then allows journalists to test the platform shortly thereafter. I think that will probably continue to be the case. In recent years, Intel has also showcased a few applications that take advantage of local AI. My guess is that we’ll see something in this regard, as well, possibly focusing on agentic AI. An Intel “Panther Lake” Core Ultra 300 chip.Intel It’s likely that Intel will also set the stage for “Nova Lake,” its next desktop processor platform that the company has already disclosed for 2026. Before that, however, the so-called “Arrow Lake Refresh” chips are expected to debut, with minor tweaks to the clock speeds and a slight upgrade to the core count (8 performance cores, 12 efficiency cores), especially in the lower tiers. But with Arrow Lake’s reception being just lukewarm and with small gains attached to the refreshed parts, I wouldn’t expect that Intel pays this a lot of lip service. Qualcomm: Selling Windows on Arm Qualcomm hopes laptop makers and all-in-ones will sign on to use its Snapdragon X2 Elite chips.Mark Hachman / Foundry No real surprises here, either. Qualcomm has already announced its Snapdragon X2 Elite platform with a variety of internal processor cores that together push towards 5GHz and an industry-leading 80 TOPS. Nobody really expects Snapdragon PCs to be gaming machines…and yet Qualcomm can never quite exclude gaming from the conversation, either. Qualcomm says the X2 Elite’s gaming performance has doubled, so expect to see more games being played on Snapdragon laptops. The big mystery, though, is how many laptops OEMs will design around the Snapdragon X2 Elite chips. the uptake of Snapdragon X Elite laptops wasn’t outstanding. But Microsoft and Qualcomm are determined to make Windows on Arm happen. Mark Hachman / Foundry Will we see desktop announcements from Qualcomm? Almost certainly not as a separate chip, but the company has teased a radically small mini PC reference design as part of the Snapdragon XE2 reveal, as well as an all-in-one desktop with a XE2 system built into the base of the monitor stand, so anything is possible. AMD: the one gamers want to buy For gamers and enthusiasts, AMD clearly won 2025, at least from a CPU perspective. Sure, you can focus upon the Ryzen 9000X and its initial performance hiccups. But AMD instead won big with its Ryzen 9000X3D parts, specifically the Ryzen 9 9950X3D: gobs of V-cache equated to gobs of performance, too. Remember when Threadripper was the chip AMD fans couldn’t stop talking about? What impressed me, however was how good AMDs mobile Ryzens were. AMD’s mobile processors were crap for years (good riddance, A-series) but the Ryzen AI 300 checked the NPU box while delivering leading performance with good battery life, too. Now AMD is ready to pass the torch from “Strix Point” to the Zen 5 “Gorgon Point” processor: the Ryzen AI 9 HX 470 has already leaked via Geekbench, running at 3.1GHz with a total of 12 cores. That’s a very good start, though I’m just as interested seeing how this chip handles the challenges of maintaining performance as well as long battery life. TechPowerUp noted that there’s an AI 5 430 floating out there, too. AMD The wild card? The Ryzen AI Max and Max+, which also uses gobs of cache, a wide, fast memory bus, a super-sized integrated Radeon GPU, and addressable memory of up 96GB. “Strix Halo” combines all three to allow the chip to serve as both a moderately powerful gaming processor as a vehicle for running local LLMs. I tested the Framework Desktop PC with a Ryzen AI Max+ chip inside, and loved it. The Framework Desktop: fun, lovely, powerful.Alex Esteves / Foundry If AMD is just now debuting Gorgon Point (and no other processor) I wouldn’t expect an upgraded AI Max chip quite yet, though I would look to the Gorgon Point chip for hints in that eventual direction. AMD has been making a lot of noise upgrading its associated ROCm software, which can boost the performance of applications through software improvements alone. This is an easy win, and a hand AMD will keep betting on for months to come. Swinging back to the desktop front, rumors suggest we’ll see AMD reveal a new Ryzen 7 9850X3D chip with 400MHz faster clock speeds than the baseline 9800X3D, as well as a new generation of APUs with beefy integrated graphics, dubbed the Ryzen 9000G series. These would bring the excellent “Strix Point” technology found in current AMD laptops to home PCs. We’ve also heard whispers of a new high-end Ryzen 9 X3D chip, which may happen, but feels much less certain. Nvidia: Don’t expect new consumer GPUs Adam Patrick Murray / Foundry The chip company with the murkiest outlook is Nvidia, hands-down. Earlier this year, rumors of an “RTX 50-series Super refresh” with more memory and other tweaks swirled before dying down a couple months back. The recent extreme RAM crunch probably put an end to those ambitions, and we don’t expect Nvidia to announce any new desktop or laptop GPUs at CES — especially considering the entire RTX 50-series launched just last year. Nvidia often brings flashy new technology and features to CES that have nothing to do with chip launches, like ACE AI companions for video game NPCs, Half-Life 2 RTX Remix, and yesteryear’s “BFD” monitor push, so there may be relevant news from Team Green. Surprises happen on the Las Vegas strip daily. We’ve heard scuttlebutt that Nvidia may have something up its sleeve surrounding monitor technology this year. As CES 2026 nears the opening week of January, PCWorld will be there. Stay tuned: the curtain is rising on 2026. Brad Chacos helped contribute to this report. Read...

The company claims the Apex Pro Gen 3 is the fastest gaming keyboard in the world, featuring new magnetic switches, improved comfort, and quieter typing. We took a closer look to see what’s behind the hype and whether the premium price is justified. Friedrich Stiemer SteelSeries Apex Pro Gen 3: Design and ergonomics The SteelSeries Apex Pro Gen 3 makes an impression as soon as you unpack it. The housing consists of a robust aluminum top and a solid plastic base. Weighing around 2.42 pounds, it sits firmly on the desk. Nothing wobbles, nothing slips. A practical highlight is the magnetic palm rest, which adheres firmly to the lower edge and offers a pleasantly soft surface. It provides noticeable relief for the wrists, especially during long gaming sessions. The keyboard is full-size, including a number pad, making it ideal for anyone who writes or does office work. However, with dimensions of around 436 × 139 × 40 millimeters, it does take up a fair amount of desk space. Friedrich Stiemer The RGB lighting is remarkably even. Thanks to the new double-shot PBT keycaps, the light not only shines through the labeling, but also from the sides. These keycaps are known for their durability and abrasion resistance, offer a secure grip, and hardly discolor over time. One small disadvantage is that PBT keycaps are more expensive to manufacture and can feel slightly rougher than ABS caps. In dark rooms, this looks spectacular without being distracting. The matte finish looks high quality and hardly attracts fingerprints. Friedrich Stiemer SteelSeries Apex Pro Gen 3: Accessories In addition to the keyboard itself, the box contains a detachable, braided USB-C cable, the magnetic palm rest, and a keycap remover. Replacement caps or other extras are not included. While they aren’t essential for a premium keyboard in this class, their presence would’ve been a welcome bonus. Friedrich Stiemer SteelSeries Apex Pro Gen 3: Technology and features At the heart of the SteelSeries Apex Pro Gen 3 are the new OmniPoint 3.0 switches, manufactured by Gateron. These magnetic switches register keystrokes not mechanically, but via a Hall-effect sensor. This is a technology that works with magnetic fields to measure key travel (without contact) and with extreme precision. The switches have a linear feel with an actuating force of around 45 grams, which enables fast and consistent input. The standout feature is the per-key adjustability, allowing actuation depth to be set anywhere from an ultra-fast 0.1 mm to a full 4.0 mm. Friedrich Stiemer In practice, this means that if you need fast response times in shooters, you can set the buttons to extremely fine triggering. If you prefer precise typing, increase the depth for more typing control. The customization takes place in the SteelSeries GG software and is saved directly to the keyboard. This allows users to play with their saved profiles even without the software installed. Not all keys are equipped with the more expensive OmniPoint switches. While the main block uses them, the function row and number keys rely on classic linear SteelSeries Red switches. This is hardly noticeable in everyday use, but it’s still worth noting. There is no hot-swap function for replacing the switches. SteelSeries Apex Pro Gen 3: Performance The polling rate is 1,000 Hz. That’s solid, but not record-breaking. Some high-end keyboards now offer up to 8,000 Hz. This means that the SteelSeries Apex Pro Gen 3 registers inputs up to 1,000 times per second, which helps keep input latency very low. The keyboard also supports N-key rollover and anti-ghosting, so that multiple simultaneous keystrokes are reliably recognized. This is especially important for fast-paced games. Friedrich Stiemer One highlight is the “Rapid Trigger” function, which allows a key to reset and actuate again as soon as it is lifted slightly. In fast-paced games such as Valorant or Counter-Strike 2, this enables lightning-fast direction changes. In combination with “Dual Action Keybinds” (i.e. double assignment depending on the depth of pressure), the SteelSeries Apex Pro Gen 3 becomes a serious tool in esports. One button can perform two actions: a light press activates walking, for example, while a stronger press in the same keystroke activates sprinting. This is ideal for dynamic movements in games such as Apex Legends or Call of Duty. SteelSeries has also improved the keyboard’s acoustics. A layer of damping material now sits between the circuit board and the base. As a result, it’s much quieter than other mechanical keyboards. It produces more of a gentle “thock” instead of the typical click-clack. Friedrich Stiemer SteelSeries Apex Pro Gen 3: Software and operation Setup via the SteelSeries GG software is straightforward. Here you can set the trigger point for each button, adjust the lighting, program macros, or manage profiles. Particularly convenient are the predefined presets for well-known games such as Apex Legends, CS2, and Fortnite. Friedrich Stiemer An integrated OLED display in the top right-hand corner shows system information, volume, profiles, and incoming Discord messages. It can also be customized with personal text or a small logo. Together with the aluminum rotary wheel, the display also doubles as a hub for media control. Here you can adjust the volume, hit play or pause, and modify the lighting. However, there are no dedicated media buttons, which is a bit of a shame at this price point. SteelSeries Apex Pro Gen 3: Everyday life and gaming In everyday use, the SteelSeries Apex Pro Gen 3 proves to be a genuine all-rounder. It feels pleasantly direct and precise when typing and reacts lightning-fast in gaming situations. Shooters, in particular, benefit from the low latency. When playing Valorant and Call of Duty, keys responded practically without delay. The keyboard also impresses with long texts. The stroke remains soft, the typing noise discreet, and the palm rest ensures comfort. Anyone who has ever experienced the difference between 0.1 and four millimeters of actuation will understand how finely the typing behavior can be tuned. Friedrich Stiemer The only downside is that, with its weight and wired connection, the Apex Pro Gen 3 is clearly designed as a desktop keyboard. If you’re usually on the move, it’s better to opt for the TKL or wireless version. That version, however, comes with second-generation OmniPoint switches. Read...

A reliable indicator of the air quality in offices, classrooms, or living rooms is the CO2 content. In fresh air, the concentration of carbon dioxide is around 400 ppm. This stands for “parts per million”, in this case 400 CO2 molecules per million air molecules. Although this is only 0.04 per cent, it has a noticeable effect. Indoors, the concentration rises rapidly due to human respiration (ie. breathing). Surprisingly, during a film screening in a movie theater, CO2 levels of several thousand ppm can be quickly reached. If CO2 levels are high enough, this can lead to lack of concentration, tiredness, and headaches. A CO2 measuring station can tell you when it’s the right time to open the windows—fresh air is needed if CO2 levels reach 1500 ppm or higher. What you’ll need Firstly, you need a Raspberry Pi with a reasonably up-to-date Raspberry Pi OS. It doesn’t matter which Raspberry model you use. You also need a CO2 sensor. The MH-Z19C sensor from the Chinese manufacturer Winsen Electronics Technology is used in this article. The MH-Z19B model works in the same way. When buying, you should choose a model with pins, otherwise you will have to solder it yourself. Pins or headers are small pins that you use to connect the sensor to the Raspberry Pi. The version with headers is available on Amazon so make sure you choose that version when you buy it. Finally, you will also need jumper wires. You will need the female/female variant for the sensor. Overall, the investment is less than $40, whereas professional CO2 measuring devices cost many times more if you were to buy ready-made models. Important: To read out the sensor, the Raspberry Pi communicates via the serial interface, which is deactivated by default. To change this, use the tool raspi-config and select “Serial Port” under “Interface Options”. How the sensor works The MH-Z19C (or B) is a non-dispersive infrared sensor (NDIR). These are based on the concentration-dependent absorption of electromagnetic radiation in the infrared wavelength range. Carbon dioxide absorbs infrared radiation in a specific and measurable way. The light source transmits IR radiation through the air to be measured by the actual sensor. A filter is attached to the front which allows the absorption wavelength of the target gas to pass through. If the concentration increases, the absorption increases according to Lambert-Beer’s law and the signal decreases accordingly. The sensor determines the resulting light intensity and converts it into ppm. How to connect the sensor to the Raspberry Pi. The sensor should be viewed from the underside. Foundry Setting up the circuit To set up the circuit, first shut down the Raspberry Pi and disconnect it from the power supply. Then connect the circuit board to the sensor. You will need four jumper wires female/female, i.e. with sockets at both ends. You can see the function of each connection on the underside of the sensor. Connect pin 6 of the sensor (labelled “VCC” or “Vin”) to pin 4 on the Raspberry Pi. This is the power supply with five volts. Pin 4 is the second from the top on the right-hand side of the GPIO strip. Now connect pin “GND” (7) on the sensor to pin 6 on the Raspberry board. This is the earth wire. It is located directly under pin 4. Halfway through, continue on the other side of the sensor, which has five connections: Pin “Rx” (2) on the sensor must be connected to pin 8 on the mini computer, directly under pin 6. Finally, connect pin “Tx” (3) on the sensor to pin 10 on the Raspberry Pi, directly below pin 8. The illustration above shows the complete setup again. Finally, start the Raspberry Pi by reconnecting it to the power supply. Read out measured values The CO2 sensor is ready for use. A Python script is needed to read out the current CO2 value. Thankfully, one was developed by a Japanese developer – just for information, to explain the Github address. You install the script together with other components by opening a terminal on the Raspberry Pi and entering the following command: git clone https://github.com/UedaTakeyuki/mh-z19.git Then change to the newly created folder “~/mh-z19” and execute the installation script: ./setup.sh To determine the current CO2 value, use this command in future: sudo python -m mh_z19 You will receive a result such as “{“co2?: 3128}”. The unit is the current ppm of CO2. The measured values can be automatically displayed online and clearly show the effect of ventilation. Foundry Measured values online Always reading out the measured values manually on the Raspberry Pi is annoying and too tedious in the long run. So it’s better to display the measured values online over time. Use a free online service to access the history of the measured values via PC or smartphone. Go to monitor3.uedasoft.com and enter an e-mail address and password to log in. You will receive a “view_id”, which you do not need. Click on the menu item Elements. Make a note of the second letter combination in the list, in the example “prgrvpqg”, and set the corresponding option to Active. Click on Save to finalize the setup. Now open a terminal on the Raspberry Pi and switch back to the “mh-z19” folder. There you call the command ./setid.sh [abcdefgh] replacing the sequence of letters with the eight-digit letter combination that you have just noted. This call is used to check whether everything is working properly: sudo python -m pondslider If the word “true” appears in the bottom line of the output, then everything is OK. In order to regularly receive measured values from now on and enter them in the Monitor app, enter the command ./autostart.sh --on In the browser, you can now see how the diagram on the Monitor page grows by one measured value every five minutes. The number of measured values displayed can be set directly below using the “Settings” button. To cover ten hours, you need 120 values. With the diagram, you can see at a glance whether someone has been airing the room while you were at lunch or shopping. The graph with the measured values can also be conveniently called up with a smartphone and downloaded as a CSV file via the “Download” button in order to analyze it in Excel. After rebooting the Raspberry Pi, the measurement script restarts automatically. The concept can be expanded further. With a red LED, a suitable 330 Ohm resistor and a slightly modified Python script, a circuit can be created in which the LED lights up as soon as the measured value exceeds a specified CO2 limit value.

Pulsar pushes the limits with its X2 Crazylight Medium, an FPS-focused mouse that weighs just 39 grams. In this review, we’ll explore whether this featherlight wonder delivers in real-world gameplay. Pulsar X2 Crazylight Medium: Design and features The Pulsar X2 Crazylight Medium lives up to its name: the mouse only weighs around 39 grams, which is almost unbelievably light for a wireless mouse. By comparison, even ultra-light competitors like Logitech’s G Pro X Superlight 2 at around 60 grams or Razer’s Viper V3 Pro at 54 grams are about 20 grams heavier. Pulsar achieves this weight through careful internal weight savings. The result? The Pulsar X2 Crazylight Medium feels surprisingly stable despite its lightweight design. The housing neither creaks nor rattles during everyday use, and the buttons sit firmly without any annoying wobble. Friedrich Stiemer The surface is matte and smooth, which makes for a pleasant feel, but it can become a little slippery with very sweaty hands. Optional grip tapes help here. It would have been a nice touch if the manufacturer had included them by default. The shape and dimensions of the Pulsar X2 Crazylight Medium follow the popular Pulsar X2 design in a slightly shrunken version. The Medium model is around 12 centimeters long, 6.3 centimeters wide, and has a flat, symmetrical body. This allows the mouse to sit comfortably in the hand, especially for claw-grip and fingertip players. Those with medium-sized or small hands will find the low, wide shape extremely comfortable. The mouse doesn’t completely fill the hand, but it provides plenty of control for quick movements. On the other hand, the Pulsar X2 Crazylight Medium may feel a little small for larger hands. Pulsar also offers a large and a mini version. Friedrich Stiemer Pulsar X2 Crazylight Medium: High-end sensor Despite its minimalist design, Pulsar doesn’t skimp on top-level technology. At the core of the mouse is Pulsar’s exclusive XS-1 sensor, which is based on Pixart’s PAW9350. This optical sensor supports an impressive 32,000 DPI resolution, 750 IPS, and 50 G acceleration. That’s more than enough for extreme sensitivity settings or even 360-degree spin shots in shooters. Friedrich Stiemer Pulsar also offers an optional polling rate of 8000 Hz (8 kHz) via 2.4 GHz radio. By default, the mouse transmits at 1000 Hz, which is already very responsive. However, if you want every possible millisecond and have the right hardware, you can increase the polling rate up to 8000 Hz using a separately sold dongle. Currently, only a few mice like the Logitech G Pro X Superlight 2 (Lightspeed 2) support such a higher wireless rate out of the box, without replacing the receiver. In practice, the difference is only noticeable in professional esports or with high FPS displays. For most users, 1000 Hz is preferable given the potential side effects… but more on than later! Friedrich Stiemer It’s especially pleasing that Pulsar uses specially developed optical switches, which should last up to 100 million clicks and is designed to prevent double-click problems. The click feel and mouse wheel are subjectively different from mechanical switches. In the case of the Pulsar X2 Crazylight Medium, we noticed slightly less “rich” feedback, but clearly defined scroll steps. This is largely a matter of taste, though. Friedrich Stiemer Pulsar X2 Crazylight Medium: Tiny battery Speaking of side effects, the radical lightweight construction does have its drawbacks. In order to reduce the weight so drastically, Pulsar has cut corners, especially with the battery and the base of the housing. The battery is tiny. Pulsar itself claims a battery life of up to 65 hours, but this figure is probably only valid under the best conditions. In everyday use, you’ll have to charge the mouse more often than usual, especially when using high polling rates. The battery drains rapidly, sometimes after less than 10 hours of continuous use. In 1000 Hz mode, the mouse lasts a few days depending on the usage profile. In our experience, it lasted around five to seven days with average gaming time. This result is fine, but it’s significantly shorter than other competitors. Logitech’s Superlight 2, for example, lasts up to 90 hours. Friedrich Stiemer The second compromise concerns the underside. The X2 CrazyLight has a skeletonized base plate to shave off some weight. In concrete terms, this means that, in addition to the PTFE gliding feet (Pulsar supplies smaller “dot” skates in the package), there are recesses through which you can see inside–even the battery is partially exposed. While this design saves on weight, it also exposes the electronics to dust and dirt. This isn’t a major problem in a clean gaming environment, but we’d recommend not using the mouse on dirty or crumbly surfaces. In more unusual scenarios, you could theoretically push the battery through the openings, but this is unlikely to happen in normal use, unless you finger the underside of the mouse with sharp objects. Overall, we find the compromise acceptable. Most gamers will appreciate the weight advantage more than a fully closed base plate. Friedrich Stiemer Pulsar X2 Crazylight Medium: Performance In FPS use, the Pulsar X2 Crazylight Medium delivers immediate, almost weightless handling. Fast flick shots are precise, and changes in direction feel effortless thanks to the mouse’s low weight. The combination of a high-precision sensor and optical switches creates a direct, responsive gaming experience, which is especially noticeable in titles like Valorant or Counter Strike. You also benefit from the precise fine control in tactical shooters, as even slow, deliberate movements are tracked accurately. Friedrich Stiemer Away from shooters, the mouse still performs reliably. In MOBAs like League of Legends, you benefit from the fast responsiveness of the buttons, although the limited number of additional buttons may be a drawback for some folks. In action RPGs like Diablo, the mouse feels comfortable even during longer sessions thanks to its lightweight casing. The precise tracking also makes it well suited for creative tasks, such as image cropping or detailed work in graphics programs. The symmetrical shape supports smooth control, making long office or browsing sessions comfortable and effortless. Read...
