When Valve's first hardware hire, Jeri Ellsworth, tweeted back in February that she was fired from the company, we were disappointed but also intrigued by what she meant by "time for new exciting projects." Well we finally saw what she's been up to here at at Maker Faire 2013. It's called Cast AR, and it's a pair of 3D augmented-reality glasses that she and former Valve programmer Rick Johnson were working on at Valve before they left.

The model we saw is still in the early prototype stages, but the concepts are already in place. Perched atop a pair of active shutter glasses are a couple of miniature LCD projectors, which bounce images from a connected computer onto a special reflective surface at a 120Hz refresh rate. A camera module sits on the eyewear's bridge and monitors an array of infrared LEDs embedded in the reflective surface. This allows for quick and accurate head tracking. Join us after the break for our impressions and stay tuned for our video interview with Jeri Ellsworth.

We know that "wherefore art thou?" was about Romeo, but if your question was for (Dell's) Ophelia, then it's likely more "when art thou." The answer? July. The Android pendrive / USB computer we saw back at CES may be one of many, but distinctive thanks to its mainstream PC-maker origins. We're still lacking a lot of the specifics, other than that there's WiFi, Bluetooth, Wyse PocketCloud integration, plus, of course, HDMI and Android 4.something. There will likely be a few enterprise-friendly features too (administration tools, remote wiping) reports PC World. As usual, developers will get their hands on them first, with -- interestingly -- some cable and telecoms companies potentially stocking it too -- though no specifics at this time. So, the $100 Dell might not be the portable you'd love for this price, but maybe the USB PC finally crossing over?

With much of its information obscured it's hard to say what Google has planned for this new device revealed by its FCC filing, but the model number at least indicates someone has a sense of humor. Called an "H840 device" and rocking the model number H2G2-42 (Hitchhiker's Guide to the Galaxy - 42, the ultimate answer to the question of life, the universe and everything) it has WiFi of the 802.11 b/g/n varieties, but that's all we know for sure. The natural question is whether this is a proper revamp of / follow up to the failed Nexus Q project, particularly with its appearance coming so closely after the unveiling of its Google Play Music All Access subscription. Of course, Google has no shortage of mysterious device projects in store, we're hopeful this one will reveal all of its secrets soon.

There are plenty of wonderful things about train travel: the leg room, the scenery, the lack of security pat-downs. The WiFi, on the other hand, has long been the slowest thing about Amtrak. The company announced today that it's finally doing something about its frustratingly sluggish service, upgrading wireless on select trains, including the Acela express between Boston and Washington DC and a few California lines like the Capitol Corridor, Pacific Surfliner and San Joaquin. Travelers to other destinations will have to wait a bit longer for quicker load times -- Amtrak has promised that the rest of its WiFi-equipped trains will be upgraded by "late summer."

Stitcher just announced a new car mode for the iPhone version of its radio and podcasting app, bringing a simplified interface that works in both portrait and landscape positions. Accessible by tapping the Stitcher logo at the top of the screen, car mode offers a pared-down version of the app's standard UI, with bigger buttons and only the essential audio controls. It's nowhere near as flashy as Stitcher's BMW integration, mind you, but the point is to keep your eyes on the road and off your iPhone's screen. The app gets a few other updates this time around: a front page with top headlines, one-tap access to shows and podcasts you're searching for and improved playback when you're picking up in the middle of a show. Head to the source link below to give the app a spin, and drive safely!

In all honesty, Blake Griffin himself could start a social network that served no purpose outside of featuring his dizzying (and disgusting, if you will) array of dunks, and it'd probably go over quite well. Instead, he -- along with other superstars in the National Basketball Association -- will soon see replays of in-game highlights making waves across Twitter in more official fashion. Hot on the heels of a deal between ESPN and Twitter comes this: a partnership between the NBA and the aforesaid social network that'll get video highlights to the world while the game is still ongoing.

#NBARapidReplay will be the hashtag to watch for as the playoffs progress, and as you'd expect, short advertisements will appear alongside those clips. Twitter's foray into the television universe is hardly a new one, but it's becoming ever more obvious that the company is following the ad dollars into the homes of everyday viewers. Up next? A deal to tweet highlights from the 2014 Masters golf tournament... but only in extremely soft spoken, lowercase, predominantly pompous characters.
