The world is full of wireless servers -- or at least some of it is. There are still many places, including parts of the United States, where you can have all the laptops, smart phones, and other wireless-capable devices you want, but there's no server that caters to them. Enter LibraryBox. It's open source and it runs on a variety of low-cost, low-power hardware. The project's website calls it "portable private digital distribution."

A lot of people obviously like this project and wish it well. LibraryBox ran a Kickstarter campaign in 2013, hoping for $3000, and raised $33,119. But today's interviewee, Jason Griffey, can explain his project better than we can, so please watch the video (or read the transcript) if you want to learn more about LibraryBox -- including the story behind the project's name.

If you go to a sci-fi or gaming convention you'll see people in exotic "character" costumes, often holding exotic props, with some of the most popular being futuristic firearm mockups of one sort or another. Who makes all these cool fannish items? A whole bunch of artists and artisans, including Michelle Sleeper (who says she got tired of jokes about her name many years ago). She's not only one of these artisans, but is also a committed 3-D printer user, since 3-D printing is how she forms a high percentage of her props (with the word "props" being used here in the theatrical rather than the nautical sense). To keep up with what Michelle is making, you should check her blog. One of her most interesting posts, titled Atlanta Mini Maker Faire: On missing deadlines, failure, and triage, is about preparing for the event where Timothy Lord met and interviewed Michelle.

Even if gamer gatherings and SF conventions aren't your thing, the interview (along with the links above) gives a nice glimpse into the life of an independent artisan who uses technology to create a lot of her art. (Alternate Video Link)

Add some material-handling devices and you'd have software-controlled Waldos, first described by Robert A. Heinlein in the 1942 short story titled Waldo. So while the idea of a pair of artificial eyes you control by moving your head (while looking at the area around the artificial eyes, even if it's in orbit), sounds like futuristic fun, especially if you use an Oculus Virtual Reality device instead of an LED screen, it not only hasn't caught up with science fiction, but is a fair ways behind science fact. Still, the idea of being able to control a vision system deep under the sea or in orbit around Saturn is certainly interesting in and of itself. (Alternate Video Link)

Sawaiz Syed's LinkedIn page says he's a "Hardware Developer at GSU [Georgia State University], Department of Physics." That's a great workplace for someone who designs low cost radiation detectors that can be air-dropped into an area where there has been a nuclear accident (or a nuclear attack; or a nuclear terrorist act) and read remotely by a flying drone or a robot ground vehicle. This isn't Sawaiz's only project; it's just the one Timothy asked him about most at the recent Maker Faire Atlanta. (Alternate Video Link)

This is a "wet" submarine. It doesn't try to keep water out. You wear SCUBA gear while pedaling it. And yes, it is powered by a person pushing pedals. That motion, through a drive train, makes manta-style wings flap. This explains the name, since rays are Batoids, and this sub is a fake Batoid, not a real one. It's a beautiful piece of work, and Martin Plazyk is obviously proud to show it off. He and his father, Bruce, operate as Faux Fish Technologies. Follow that link and you'll see many photos, along with a nice selection of videos showing their creations not just in static above-water displays, but in their natural (underwater) element. Meanwhile, here on Slashdot, Martin tells how Faux Fish subs are made. (Alternate Video Link)

Eggcyte has been working on this for two years. It's on Kickstarter now; a personal server you can use to share music, video, text, and just about anything else without resorting to cloud-based services where one weak password can put your private celebrity photos (you are a celebrity, right?) into the wrong hands. If you suddenly decide you don't want to share the information on your Egg any more, turn it off. If you suddenly have something new to share, like a video you just shot of the Loch Ness Monster capturing an alien spaceship, you can connect your Egg to the Internet anywhere you find a wireless access point. The main thing, say the Eggcyte people, is that your data is yours and should stay that way. Facebook and other cloud-based "sharing" companies use your data to learn about you. Here in the U.S. their primary purpose may be to show you ads for things you might want to buy. In more repressive countries, cloud-based sharing services may use your private data in ways that could be hazardous to your health. Of course, our government people would never keep track of what we post on Twitter and other online services... or would they? (Alternate Video Link)

Chris Gordon works for a high-technology company, but he likes analog meters better than digital readouts. In this video, he shows off a bank of old-fashioned meters that display data acquired from digital sources. He says he's no Luddite; that he just prefers getting his data in analog form -- which gets a little harder every year because hardly any new analog meters are being manufactured.

If you're in a wheelchair, wouldn't it be nice to have your chair automatically alert a caregiver if changes in your heart rate or another vital sign showed that you might be having a problem? And how about helping you rate sidewalks and handicapped parking spaces to help fellow wheelchair users get around more comfortably? Steven Hawking endorses the idea, and the Connected Wheelchair Project, in this short video. (You can see our interviewee, David Hughes, at 0:58 and again at 1:38.) This is an Intel project, in conjunction with Wake Forest University, run by student interns. | Besides helping wheelchair-dependent people live a better life, the Connected Wheelchair Project may help prevent Medicare fraud, says Hughes in our video interview with him. Falsified requests for durable medical goods are a huge drain on Medicare's budget. What if a connected wheelchair spent all of its time far from the home of the person to whom it was assigned? That would be a red flag, and investigators could follow up to see if that wheelchair was in legitimate hands or was part of a scam. | The Connected Wheelchair is still proof-of-concept, not a commercial product. Will it see production? Hard to say. This may never be a profitable product, but Intel CEO Brian Krzanich has said that that this project is an example of how “the Internet of Things can help change lives.” (Alternate Video Link)
