    Designing a 3D-Printed Prosthetic Arm

    3D printing isn't just for prototyping or making toys--it can also be used to manufacture working prosthetic limbs. We're joined by designer Jacky Wan this week to learn about his work with the Enabling The Future, an organization developing a 3D-printable arm prosthetic. Jacky's design goes above and beyond the requirements of the project, and looks beautiful too!

    Tested In-Depth: Apple TV (4th Generation)

    After living with the new 4th generation Apple TV for a month, Norm and Patrick Norton evaluate how this set-top box performs against its competition. There's a lot to like about its interface and implementation of video streaming apps, but a few things bug us about its remote design and consistency of voice-control. Here's why it's not the cord-cutting device for everyone.

    Hands-On: VR Zombie Shooting in Arizona Sunshine

    Developer Vertigo Games are making a zombie shoot-'em-up for the HTC Vive virtual reality headset, and we demo it at the recent SteamVR Developer Showcase. Afterward, we chat with the studio about how it's making zombie shooting fun, interesting, and challenging in room-scale VR.

    Hands-On: VR Shooting Gallery in Space Pirate Trainer

    Here's one game we played at the SteamVR Developer Showcase that feels like the perfect virtual reality arcade game. Space Pirate Trainer shows that there's a lot of complexity and tuning needed to get one just one basic mechanic feeling right in VR. They've got the shooting gallery down!

    Hands-On: VR Multiplayer Shootouts in Hover Junkers

    Hover Junkers is the first multiplayer shooter we've played in virtual reality, and we loved every minute of our demo in it. We chat with the game's lead designer to learn how VR enhances deathmatch gameplay, and how flying RC quadcopters and playing with airsoft informed Hover Junkers' design.

    Hands-On: Cloudlands VR Minigolf on the HTC Vive Pre

    Virtual reality can take simple activities like miniature golf and put them in fantastic environments. We try Cloudlands: VR Minigolf at the recent SteamVR Developer Showcase and learn how replicating the feel of accurately putting a golf ball is surprisingly complicated.

    Hands-On: Fantastic Contraption with HTC Vive Pre

    At the recent SteamVR Developer Showcase, we got more hands-on time with Fantastic Contraption, a creative physics-based puzzle game that makes excellent use of virtual reality. We chat with the developers to learn how they're experimenting with physics and user interface in VR.

    Hands-On: The Gallery with HTC Vive Pre

    We go hands-on with The Gallery: Call of the Starseed, an adventure game made for room-scale virtual reality. We chat with the game's developer about how you traverse large spaces in The Gallery, the challenges of designing VR puzzles, and how performance capture is augmented with headsets.

    Hands-On: Virtual Reality Portals in Budget Cuts

    At the recent SteamVR Developer Showcase, we played a little of Budget Cuts, a virtual reality stealth/puzzle game using room-scale environment and portals for locomotion. We chat with one of its creators to learn how effective portals can be for VR gameplay, and share some demo impressions.

    Tested In-Depth: Dell XPS 13 Laptop

    Our senior technology correspondent Patrick Norton joins us this week to review the Dell XPS 13 laptop! This 13.3-inch version of the beautiful XPS 15 also runs on an Intel Skylake Core i5 processor, has a solid keyboard and trackpad, and sports that brilliant display.

    Testing the Folger Tech 2020 i3 3D Printer

    I had been in the market for another 3D printer for my fabrication fleet, and I had my eye on a few machines during Black Friday. I narrowly missed a great sale on a Wanhao Duplicator i3 for a cool $299, and instead I settled on a Folger Tech 2020 i3 kit on sale with an LCD panel (currently priced at $280). Here's how it's been performing for me, and what you can expect for a 3D printer of this price.

    I had done some reading on this particular kit so I knew to expect some hurdles during it's construction. The biggest complaint that the community has - and indeed I have too - is that the build manual has several mistakes and blatant inaccuracies that Folger Tech has yet to fix. There's some simple stuff like typos of bolt dimensions - using one bolt length in one sentence and another length in the next sentence, leaving you to figure out which one they really mean. These are easy to figure out. But then there's the problem where it tells you to mount the X-axis end stop on the wrong side, and if you don't understand why 3D printers are put together the way they are, you'll have a difficult time understanding why it's moving in the "wrong" direction and why it won't home properly. I highly recommend reading the manual fully before starting to make sure you know what to expect.

    There is an absolutely massive thread on the RepRap forums which contain a huge amount of information and fixes. As of this writing, the thread is at 88 pages long and I've only managed to work backwards through about half of it. If you're considering one of these kits I recommend at least skimming through the forum thread on your own, but I've tried to compile the biggest issues and fixes from my experience here.

    Meet the Hexo+ Autonomous Camera Drone

    This aerial camera holds a GoPro on a three-axis stabilizing gimbal and flies autonomously based on smartphone commands. We ask its creators how its flight algorithms work and why they chose not to enable direct transmitter control.

    Meet the Acton Blink Electric Skateboard

    Last year, we checked out Acton's motorized "Rocket Skates" at CES, which were a bit impractical for regular use. Acton's new electric skateboard, the Blink, may be more useful. We chat with Acton co-founder Peter Treadway about what makes Blink different from other electric skateboards, and give it a quick test ride!

    Meet the ELAC Uni-Fi UB5 Bookshelf Speakers

    Meet Andrew Jones, legendary speaker designer who's now engineering amazing audio gear for ELAC. At CES, Patrick Norton could not stop gushing about ELAC's new Uni-Fi UB5 bookshelf speakers, which only cost $500 for a pair (but sound like they cost thousands). Patrick gets the opportunity to chat with Andrew about speaker design and what makes for good home audio.

    Flying FPV Drones with Avegant Glyph Headset

    Avegant's Glyph was conceived of as a way to watch movies and play games in a head-mounted display, but its more interesting use is as a FPV viewer for camera-equipped drones. We check out the final production version of the Glyph and test it with the DJI Phantom 3 and Inspire 1 with head-tracking.

    Meet Dell's New 30-Inch OLED Monitor

    We meet up with Patrick Norton while at CES to check out Dell's new 30-inch OLED monitor. This is only of the most beautiful desktop displays we've ever seen--a prestige product priced at a whopping $5000. Plus, we quickly check out Dell's new 2-in-1 Core-M notebook.
