Audi proves two little screens are better than one big screen – TechCrunch

Published

on

I’m spending some time in the new Audi Q8, and the car company equipped the crossover with its latest infotainment system. I love it, fingerprints, dust and all.

The grimy screens are part of the story. I could have cleaned up the screens for the photos, but I thought it was essential to show the screens after a couple of weeks of use.

There are two screens placed in the center stack of the Q8. The top one features controls for the radio, mapping system and vehicle settings. The bottom screen is for climate controls and additional controls like garage door opener and the vehicle’s cameras. Both have haptic feedback, so the buttons feel nearly real.

Both screens are tilted at the right angle, and the shifter is built in a way that provides a handy spot to rest your wrist, steadying it as you hit the screens.

Car companies are turning to touchscreens over physical buttons. It makes sense on some level, as screens are less expensive and scalable across vehicles. With screens, car companies do not need to design and manufacture knobs, buttons and sliders but instead create a software user interface.

Tesla took it to the next level with the debut of the Model S in 2012. The car company stuck a massive touchscreen in the center stack. It’s huge. I’m not a fan. I find the large screen uncomfortable and impractical to use while driving. Other car companies must agree, as few have included similar touchscreens in their vehicles. Instead of a single touchscreen, most car makers are using a combination of a touchscreen with physical knobs and buttons. For the most part, this is an excellent compromise, as the knobs and buttons are used for functions that will always be needed, like climate control.

Audi is using a similar thought in its latest infotainment system. The bottom screen is always on and always displays the climate control. There’s a button that reveals shortcuts, too, so if the top screen is turned off, the driver can still change the radio to a preset. The top screen houses buttons for the radio, mapping and lesser-used settings.

The user interface uses a dark theme. The black levels are fantastic, even in direct sunlight, and this color scheme makes it easy to use during the day or night.

The touchscreens have downsides but none that are not present on other touchscreens. Glare is often an issue, and these screens are fingerprint magnets. I also found the screen to run hot to the touch after a few minutes in the sun.

Apple CarPlay remains a source of frustration. The Q8 has the latest CarPlay option, which allows an iPhone to run CarPlay wirelessly. It only works sometimes. And sometimes, when it does work, various apps like Spotify do not work in their typical fashion. Thankfully, Apple just announced a big update for CarPlay that will hopefully improve the connectivity and stability.

The infotainment system is now a critical component. Automakers must build a system that’s competent and feels natural to the driver and yet able to evolve as features are added to vehicles through over-the-air updates. Automakers must build a system that works today and continues to work years from now.

Audi’s latest infotainment system is impressive. It does everything right: it’s not a distraction, it’s easy to use and features fantastic haptic feedback.

This enthusiast’s keyboard and trackball used to launch nuclear missiles

Published

on

There’s no telling what you’ll find on eBay—like an old keyboard and trackball originally dedicated to firing off nuclear missiles.

As detailed Tuesday by YouTube channel Pointless Tinkering, an enthusiast bought the keyboard off eBay simply because it “looked awesome” and had “some interesting buttons” saying things like “TRANSMIT,” “ABORT,” and “INITIATE.”

The keyboard and trackball were part of a larger control system for a nuclear missile silo command center. More specifically, the peripherals were part of a console used to launch Minuteman III missiles in the ’80s as part of the US Air Force’s Rapid Execution and Combat Targeting (REACT) program.

As explained by the Cold War history site Nuclear Companion and cited by Pointless Tinkering, “There is one stunning difference between REACT and the old Command Data Buffer (CDB). While the CDB had two separated workstations, in REACT, both crew are side by side. In other words, they operate in a single console with keyboard and trackball included.”

The keyboard has reed switches, which use magnets to actuate. Other parts include an Intel MD82510/B chip as a serial controller, an Intel 8051-family microcontroller, and RS422 communication chips.

After grabbing the keyboard and trackball from eBay and learning about their history, the enthusiast went to work, armed with tools like an Arduino Pro Micro (which eventually got fried) and a programmer for the microcontroller, which he acquired through Dromeda Research. He also repaired the trackball that stopped working after purchase and got both the keyboard and trackball to work with modern computers with a USB port.

“All that reverse engineering led to me creating this little interface, which has the Arduino Micro, which can emulate a mouse and a keyboard,” the owner said. There’s even custom software for the keyboard.

Of course, there’s no RGB lighting, but some keys actually do have LEDs.

Not quite RGB.

Pointless Tinkering also highlighted a “BIT key” that seems to reset the keyboard.

According to the video, both the keyboard and trackball work like regular PC peripherals, save for the Ctrl, Alt, and down keys, making the Nuclear Keyboard, as the video dubbed it, “very hard to use as a normal, daily driver keyboard.”

Pointless Tinkering said he would try to address any issues that pop up in a follow-up video. Despite its flaws, the Nuclear Keyboard is still a fascinating testament to the power of old tech and fresh minds.

Luna Display lets you wirelessly use a Mac as second Windows monitor

Sometimes you just need more screen space. You can always buy a portable monitor, but what if you could just use the systems already in your home—whether they run Windows or macOS?

Luna Display is a product by Astropad that lets you turn an iPad into a wireless second display. The $130 offering uses a dongle and works with Windows PCs and Macs. Its “headless” mode turns the iPad into the main display for a Mac Mini or Mac Pro.

Luna Display’s 5.1 update, announced this week, adds even more possibilities. The dongle can now be used with any Apple machine—not just an iPad—to provide a second display for your Windows PC or Mac.

You’re not limited to Apple’s desktops or laptops, either; Luna Display now supports adding a 4K or 5K screen to your PC as a second display. That means you could attach the 24-inch iMac with a 4.5K (4480×2520) resolution or a 27-inch iMac with a 5K (5120×2880) resolution to your Windows or Mac PC.

There are some caveats, though. If you plan to connect a 4K or 5K Mac, the machine has to be running at least macOS Big Sur. Any 5K screen connected to your Windows PC will be limited to a 30 Hz refresh rate, which is half the refreshes per second than what’s typical (60 Hz). If you’re using a Mac with Big Sur or later, the refresh rate is increased to 45 Hz. And if you’re “only” connecting a 4K screen, your refresh rate will be 60 Hz, whether the display is connected to a Windows or Apple system.

Other additions with the Luna Display 5.1 update include support for Apple’s Magic Keyboard and trackpad with a Luna Display-connected iPad. Again, this feature works whether the iPad is connected to a Mac or PC.

Note that to use Luna Display in general, you must have a system with Windows 10 64-bit, Build 1809 or later, or macOS 10.11 El Capitan or later as your main PC. The iPad must run iOS 12.1 or later, and you need either 802.11n Wi-Fi or an Ethernet connection.

With Apple and Windows historically living in such separate camps, it’s nice to see a product bring more platform agnosticism for those who aren’t completely committed to one side.

Microsoft restores individual “default browser” setting in Windows 11 preview

Published

It’s been a rough week for Microsoft’s Edge browser in the court of public opinion as users grumbled about the addition of a controversial “buy now, pay later” financing feature and another layer of pop-up messages that tries to dissuade users from installing Google Chrome. But Microsoft isn’t totally unresponsive to user criticism when it comes to Edge—the latest Dev channel Windows Insider build of Windows 11 restores a button in the Settings app for setting your default browser, something that existed in Windows 10 but is missing from the current stable version of Windows 11.

The change, originally spotted by developer Rafael Rivera, adds the default browser button to the top of the Settings app when you navigate to any browser in the “Default apps” section. The button automatically changes the default app for opening http, https, .htm, and .html files and links instead of making users change each of these associations manually (or relying on browser makers to build that capability into their browsers themselves).

For all the other file types that Microsoft Edge can handle, including PDFs, SVG files, and others, you’ll still need to change those associations manually and one at a time. But this is already how the default browser button worked in Windows 10, so it at least represents a reversion to the pre-Windows 11 status quo rather than a new hurdle to jump over.

Features being tested in the Dev channel builds of Windows are usually destined for the operating system’s next major servicing update, which for Windows 11 will happen sometime in the fall of 2022. Recent builds have begun to address some common complaints about Windows 11’s user interface changes, including tweaks to the Start menu and taskbar.
