The BIONZ XR Leap: A Technical Analysis of the Sony Alpha 7 IV Architecture
5+ min ago (280+ words) The "basic" full-frame camera category has historically been defined by compromise: good stills but crippled video, or decent video with low-resolution sensors. The Sony Alpha 7 IV is an engineering statement that attempts to end this segmentation. By inheriting the architecture of the flagship Alpha 1 and adapting it for the prosumer chassis, Sony has created a device that redefines the baseline. For the technical creative, this isn't just about megapixel counts; it's about data throughput and color bit-depth. Let's deconstruct the silicon and signal processing chain that makes this camera the new standard for hybrid workflows. The heart of the a7 IV is a brand-new 33-megapixel Back-Illuminated (BSI) sensor. Previous standards hovered around 24MP. The jump to 33MP provides a critical increase in pixel density. A high-res sensor is useless if the processor chokes on the data stream. The a7 IV utilizes the flagship BIONZ…...
Taking Electronics To A Different Level
8+ min ago (349+ words) One part wants 3.3V logic. Another wants 5V. What do you do? Over on the [Playduino] YouTube channel, there's a recent video running us through a not-so-recent concern: various approaches to level-shifting. In the video, the specific voltage domains of 3.3 volts and 5 volts are given, but you can apply the same principles to other voltage domains, such as 1.8 volts, 2.5 volts, or nearly any two levels. Various approaches are discussed depending on whether you are interfacing 5 V to 3.3 V or 3.3 V to 5 V. The first way to convert 5 V into 3.3 V is to use a voltage divider, made from two resistors. This is a balancing act: if the resistors are too small, the circuit wastes power; if they are too large, they inhibit fast signals. The second approach to converting 5 V into 3.3 V is to use a bare resistor of at least 10K. This is…...
The Apple iPhone 17 Pro Keeps Cool While Playing the Hottest Mobile Games
8+ min ago (543+ words) Its cooling vapor chamber is a standout feature for the powerful phone, though its design isn't the best for gaming. The iPhone 17 Pro playing the game Genshin Impact. The iPhone 17 Pro is the best phone Apple has ever released -- top specs, long battery life, a crisp screen and outstanding cameras. The first three also make it a great gaming device, but how great? I decided to test it to find out. And if you can find another phone that doesn't heat up when playing a graphics-intensive console-quality game like Resident Evil 8, I'd like to see it. The iPhone 17 Pro plays plenty of games well, and its App Store features mobile versions of popular PC titles like Dredge (pictured). The 6.3-inch display is large for a "smaller" phone, and its 2,622 x 1,206-pixel resolution is vibrant. Even better is its 3,000-nit maximum…...
16+ min ago (336+ words) Memory shortages are now anticipated to pose significant constraints on laptop manufacturers, as a new report states that 8GB memory configurations will become increasingly common. Memory Supply Constraints Are Now Reaching to an "Alarming Level" For Manufacturers, Forcing them to Raise Prices We are now in a timeline where manufacturers are factoring in DRAM shortages and adjusting product prices to ensure they can sustain inventory levels and maintain profitability. Firms like Dell are reported to have been implementing price hikes amounting to 'hundreds of dollars', and it is expected that products with higher memory onboard will reach an 'absurd' level.

Elon Musk’s X rolls out home and lock screen widgets for iPhone and iPad users
21+ min ago (232+ words) Elon Musk led X has finally introduced widgets for iOS, allowing users to access top news, shortcuts and notifications from their home screen and lock screen. Curiously enough, as 9to5Mac points out, the first Home Screen widget for iPhones was shown off at WWDC 20 during a teaser video for iOS 14 but the feature never really arrived. Now that the widgets on X are finally here, let's take a look at what they offer: For the Home Screen, X brings only a single widget for now called the "X News Highlights" that gives headlines about the trending topics on the social media platform. If a user clicks on any of those headlines, they will be redirected to the X app to see the full news. As 9to5Mac notes, the widget comes in three sizes: small, medium, and large, meaning they can adjust well…...
Today in Apple history: iMac Pro packs potent all-in-one punch
37+ min ago (539+ words) By Ed Hardy " 9:32 am, December 14, 2025 December 14, 2017: The much-anticipated iMac Pro finally reaches customers many months after Apple's announced the product. With a built-in 27-inch, 5K display and an Intel Xeon processor, the high-end desktop combines the features of an iMac and a Mac Pro. It is beautiful and far more powerful than earlier iMacs, but is'destined to stay in Apple's product lineup only a relatively short time. Apple unveiled the iMac Pro at its Worldwide Developers Conference in June 2017, but the machine didn't actually launch until mid-December. The powerful all-in-one came at a time when Apple hadn't released a new professional-grade desktop since the "trash can" Mac Pro of 2013. The iMac Pro was intended to be a placeholder for those needing a Mac with real power. Apple built the first model around an eight-core, 10-core, 14-core or 18-core Xeon processor with…...

Android 17 may be able to help with your car sickness by adding a new Motion Cues feature
39+ min ago (333+ words) We've been waiting for this A year ago, a new Android feature called Motion Cues was spotted hidden away in the Google Play Services code, with a launch apparently imminent. It hasn't shown up yet " but that could be about to change. Once again we're indebted to the team at Android Authority for doing the necessary digging, and it seems as though the feature is still there. However, a restriction in the capabilities of Android itself is the reason it hasn't yet launched. Motion Cues, like the equivalent feature in iOS, will draw dots over the screen that move in relation to the actual movement of the phone " in theory reducing nausea, because it means your brain won't be quite so confused as to whether you're moving or not. However, drawing those dots on top of key setting panels requires…...

52+ min ago (1703+ words) This Forza Horizon 5 PS5 review breaks down visuals, handling, content, and the key PS5 Pro enhancements that make this the definitive console version. PushSquare: We always sensed the market for Forza Horizon 5 on PS5 was humongous, but even we're a little stunned by how well it's sold. The game " which has been consistently near the top of global sales charts ever since it deployed on Sony's system " is said to have shifted two million copies in its first month on the market. Sad, i was hoping people would hold back until they release a disc version. I am one of these.. You are one of few. lol what a silly mentality @cacabunga You and me both buddy you and me both, sadly the people with short self restraint outweigh us by the millions " Waiting for a disc release as well. physical guy here…...
