AR and VR Are Not the Same The terms "virtual reality" and "augmented reality" get thrown around a lot these days, thanks to the resurgence of VR headsets heralded by the Oculus Rift and the use of AR apps and games like Pokemon Go. They sound similar, and as the technologies develop, they bleed over into each other a bit. They're two very different concepts, though, with characteristics that readily distinguish them from one another. What Is Virtual Reality? VR headsets completely take over your vision to give you the impression that you're somewhere else. The HTC Vive, the Oculus Rift, and other headsets are completely opaque, blocking out your surroundings when you wear them. If you put them on when they're turned off, you might think you're blindfolded. When the headsets turn on, however, the LCD or OLED panels inside are refracted by the lenses to completely fill your field of vision with whatever is being displayed. It can be a game, a 360-degree video, or just the virtual space … [Read more...] about Augmented Reality (AR) vs. Virtual Reality (VR): What’s the Difference?
Hasselblad's X mirrorless medium format system launched with three prime lenses, including the wide-angle XCD 3,5/30mm. But system owners craving an even wider field of view were left to adapt larger lenses developed for the company's H system. The company is filling the gap with the XCD 4/21mm ($3,750), a prime that covers the same angle of view as a 17mm on a 35mm full-frame camera. If you've got an X1D at home the 21mm is worth checking out, especially if you crave a very wide view of the world. Design: Minimalism at Work The XCD 4/21mm is all black, with a metal barrel and a large rubberized manual focus ring. Adornments are minimal, with the Hasselblad logo, the focal length and aperture, and an indicator reminding you that the front filter is a 77mm size, all in white text around the front element. The Hasselblad logo and some additional text are printed toward the base, though in a gray font that all but blends into the matte black finish. Given its coverage and angle of … [Read more...] about Hasselblad XCD 4/21mm
DIY Gaming On the Cheap If you like retro video games, you have several options. You can find plenty of older video games ported to newer systems and the PC (the Nintendo Switch is great for Neo Geo games, but oddly not for NES and SNES games). You can get a first-party classic game system like the SNES Classic Edition. You can get a cartridge-playing retro game system like the Super Retro Trio+. You can even find an original classic game system and plug it into your TV's legacy video connectors, or into an analog-to-HDMI upconverter. You can also build your own emulation-based retro game system with a Raspberry Pi. It's inexpensive, powerful, and easier to set up than you might think. All you need is a Raspberry Pi board, a microSD card, a micro USB power adapter, and a case to put it all in. And, of course, some form of game controller. Thanks to the developers of open-source software RetroPie, the LibRetro emulation API backbone, and the EmulationStation front-end, turning a $35 … [Read more...] about How to Build a Raspberry Pi-Powered Retro Video Game Console
3D printing may have started out as an expensive hobby for anyone wanting to experiment with creating things out of melted plastic, but industry soon saw the potential benefits and cost savings on offer. Boeing, for example, managed to save $3 million per Dreamliner thanks to 3D printing, and now Lockheed Martin is taking advantage of it for satellite production. Last week, Lockheed announced the completion of its largest ever 3D printing project. The parts being manufactured are huge domes meant for the top and bottom of satellite fuel tanks. The domes are made from titanium and have a diameter of 46-inches. Lockheed tried to put the size of these domes in perspective by offering some unusual suggestions as to what they could be filled with. For example, each dome can hold 74.4 gallons of coffee (1,191 8oz cups), 530 glazed donuts, 310,000 hard shell candies, or 6,225 ping pong balls. Just because it's 3D printed doesn't mean each dome isn't strong. Lockheed says the fuel tanks need … [Read more...] about Lockheed’s 3D Printed Dome Holds 74 Gallons of Coffee
