A New York Times piece (as carried by the Pittsburgh Post-Gazette) outlines a fascinating project operating in unlikely circumstances for a quixotic goal. They want to control, and return to earth, the International Sun-Earth Explorer-3, launched in 1978 but which "appears to be in good working order." Engineer Dennis Wingo, along with like minded folks (of whom he says "We call ourselves techno-archaeologists") has established a business called Skycorp that "has its offices in the McDonald's that used to serve the Navy's Moffett air station, 15 minutes northwest of San Jose, Calif. After the base closed, NASA converted it to a research campus for small technology companies, academia and nonprofits. ... The race to revive the craft, ISEE-3, began in earnest in April. At the end of May, using the Arecibo Observatory radio telescope in Puerto Rico, the team succeeded in talking to the spacecraft, a moment Mr. Wingo described as "way cool." This made Skycorp the first private organization to command a spacecraft outside Earth orbit, he said. The most disheartening part: "No one has the full operating manual anymore, and the fragments are sometimes contradictory." The most exciting? "Despite the obstacles, progress has been steady, and Mr. Wingo said the team should be ready to fire the engines within weeks."

New submitter meghan elizabeth (3689911) writes Why stop at just mimicking biology when you can biomanufacture technologically improved humans? 3D-printed enhanced "superorgans"—or artificial ones that don't exist in nature—could be engineered to perform specific functions beyond what exists in nature, like treating disease. Already, a bioprinted artificial pancreas that can regulate glucose levels in diabetes patients is being developed. Bioprinting could also be used to create an enhanced organ that can generate electricity to power electronic implants, like pacemakers.

the_newsbeagle (2532562) writes "The equipment that neuroscientists use to record brain signals is plenty expensive, with a single system costing upward of $60,000. But it turns out that it's not too complicated to build your own, for the cost of about $3000. Two MIT grad students figured out how to do just that, and are distributing both manufactured systems and their designs through their website, Open Ephys. Their goal is to launch an open-source hardware movement in neuroscience, so researchers can spend less time worrying about the gear they need and more time doing experiments."

By day John Hawley is a mild-mannered open hardware evangelist for Intel. But after hours he is the master of K-9, a robot dog he works on a little at a time. Yes, this is a Whovian thing, which is why John's K-9 looks so much like the Doctor's. But K-9 is also a pretty good dog on his/her own. No vet bills, no constant hunger, no barking at feral cats in the middle of the night, obeys every command... so maybe Dr. Who and John Hawley have the right idea when it comes to canines. Except.... aww.... my dog, Terri the Terrorist Terrier, just licked my hand. What a sweetie! Terri may not take orders from a hand-held remote, but she has a lot of other fine characteristics, including affection. K-9 is very cute in a squared-off, mechanical way, though. Hard to resist, despite a lack of soft fur and no tongue for licking his/her master's hand. (Alternate Video Link)

New submitter fffdddooo (3692429) writes I know it's something that people used to ask every few years, but answers get old so quickly. I'm an electronics teacher, and I'm wondering if it's possible to find some oscilloscope (and why not spectrum analyser?) for recommending to my students, to be able to work at home. I'm thinking of something near $50-$70. Two or three years ago, I'm sure the answer was No, but nowadays? The same reader points out two options spotted on Amazon: one that's "very cheap but Khz" (it's also a kit that requires assembly), and another that aims to be capable of 20MHz, 2-channel operation. What's out there, he'd like to know, that's not junk?

mknewman (557587) writes with a welcome followup to the broad hints that Tesla might release some of its patents for others to use patents that it has amassed. Now, Elon Musk writes on the company's blog: Yesterday, there was a wall of Tesla patents in the lobby of our Palo Alto headquarters. That is no longer the case. They have been removed, in the spirit of the open source movement, for the advancement of electric vehicle technology. Tesla Motors was created to accelerate the advent of sustainable transport. If we clear a path to the creation of compelling electric vehicles, but then lay intellectual property landmines behind us to inhibit others, we are acting in a manner contrary to that goal. Tesla will not initiate patent lawsuits against anyone who, in good faith, wants to use our technology.

Not everybody at a Maker Fair (or even Faire) is there to get kickstarted or to make a billion of whatever it is they're displaying. Ned Danyliw is one of the non-kickstarter people: an electrical engineering student displaying a quadcopter development platform he hopes can bring the cost of a quadcopter prototype down to $50 or so, or about the same price as a toy quadcopter. You can follow Ned's work step by step and see all the code at his blog, Burnt Transistors. (Alternate Video Link)

New submitter InternetOfJim writes: "This is one of the most fun weekend projects I've done in a while — a fitness tracker for my elliptical trainer. But the real agenda was to figure out how lazy I could be via web services (Keen IO and Brace IO) and development platforms (Electric Imp). Quite lazy, as it turns out. I wound up with a working device and a nice realtime dashboard with no soldering, no backend to manage, and surprisingly little original code needed beyond the sensing and power conserving parts of the firmware and a little javascript to customize the dashboard."

samzenpus (5) writes Andrew "bunnie" Huang holds a Ph.D in electrical engineering from MIT and is one of the most famous hardware and software hackers in the world. He is a contributing writer for MAKE magazine, and has worked on a number of projects ranging from autonomous robotic submarines to peel-and-stick electronics. We recently covered one of his latest projects, an open source hardware laptop called Novena which features entirely NDA-free components. Bunnie has agreed to take a break from his work and hack away at any questions you may have. As usual, ask as many as you'd like, but please, one question per post.

muterobert (2927951) writes with an update on the full immersion VR system from Project Holodeck (now renamed Survios). The system combines an Oculus DK2 with external sensors to make a fully immersive 8x'8' space "Ben Lang from Road to VR goes hands on and heads in with virtual reality technology company Survios' newest version of untethered VR system 'Prime 3'. He moves around the virtual space, holding and reloading weapons as you would in real life. 'At one point while playing, I was wielding the shotgun with two hands, with the table of weapons was on my right side. Several zombies were approaching and I needed a bit more fire power. I dropped the shotgun, reached over with my right hand to grab the tommy gun off the table, then virtually tossed it from my right hand to my left hand (because I'm a lefty), then pulled my pistol out of the holster with my right hand and continued to shoot both weapons.'" The article has a video, and it almost makes me think it's what being in the metaverse would be like.

25-year electronics veteran Conrad Lee noticed that commodity multi-channel security DVRs have both more channels than a typical household needs and more capabilities than their makers advertise -- at least, with some creative re-use of their video feeds. With a home-grown controller hooked up to an otherwise unused video channel, a run of the mill security DVR can be used as a command center for household items, like lights, locks, thermostats, cameras, or whatever else you think of) by means of controls both old-fashioned (the ubiquitous X10 devices, some of which you probably have stashed in a drawer) and new (Z-wave). He showed off his system at last month's Maker Faire -- take a look (video below) at what his clever hardware re-use makes possible, and at Lee's controller. It means giving up one (relatively) inexpensive channel, to gain capabilities that would cost quite a bit more in a ready-built system, like smart-phone control and pan/tilt control for cameras.

An anonymous reader writes "South African makerstore OpenHardware.co.za has designed and built a new RepRap-derivative 3D printer which it plans to sell for less than R5000 ($470). The first completed units are being put together now, with an eye to shipping late June. Store owner Peter van der Walt says that he designed Babybot — which has a print area equivalent to a RepRap Prusa Mendel-style machine — in order to reduce build and support costs. He's been selling various RepRap designs in kit form for two years, but as they become more popular is struggling to keep up with demand and handle returns. By sourcing more materials locally — he also designs his own controller boards — he's looking to beat the likes of RS Components and large shopping chains which have begun shipping the likes of Cubify in the country."

Last month, at Maker Faire Bay Area 2014, Timothy Lord spotted a guy wearing a very large piece of headgear that included two crossed wrenches. The guy turned out to be Mike Szczys, Managing Editor of hackaday.com, which says, "The Hackaday Prize will send one person into space for building the next evolution of hardware." That's certainly of interest to the hardware hacker/maker crowd. How they're going to arrange the space flight (probably one of those "just above the atmosphere" hops) isn't specified, but even so the contest is an interesting idea, and the Hack A Day site seems to have some interest hacks and tutorials on it. So go ahead and enter the contest -- and don't forget to take your camera with you on your flight into space, because we'll want to see pictures! (Alternate Video Link)

A while ago you had the chance to ask amateur scientist, and author of the Getting Started in Electronics and the Engineer's Mini-Notebook series, Forrest Mims, a number of questions about science, engineering, and a lifetime of educating and experimenting. Below you'll find his detailed answers to those questions.

An anonymous reader writes "Wireless security researcher Michael Ossmann asked himself: 'Could I make the gadgets that the agency uses to monitor and locate mobile phones, tap USB and Ethernet connections, maintain persistent malware on PCs, communicate with malware across air gaps, and more, by just using open source software and hardware?' In this podcast he shares his insights on what to use — and how — to duplicate hardware devices found in the ANT catalog."

An anonymous reader writes "MakerBot, in collaboration with NASA's Jet Propulsion Laboratory (JPL), is hosting a competition for the design of a future Mars base. The competition is open to any Thingiverse account holder regardless of professional or educational background. Winners will be chosen by a subjective panel of JPL and MakerBot employees based on scientific feasibility, creativity, and printability. Contest ends June 12, and contestants have to be at least 13 years old. The first place winner will receive a MakerBot Replicator 2 Desktop 3D printer and three spools of MakerBot Filament. The second place winner will receive two spools, and the third place winner will receive one spool. All three will have their design featured on Thingiverse." You can also browse the entries so far.

Lucas123 writes: 'Scientists developing smart robotic prosthetics say the lines between robots and humans is beginning to blur and that someday soon people will be able to improve their body. For example, robotic prosthetics, using a built-in computer, 100 sensors, and 17 motors, can take natural cues from a user's residual limb, giving him or her the dexterity and grace to play a piano. Robotic exoskeletons have helped people suffering from paralysis walk again and the U.S. military is just weeks away from testing a new exoskeleton. And, more than six years ago, a University of Arizona researcher who had successfully connected a moth's brain to a robot predicted that by 2022 we'll be using "hybrid" computers that run a combination of technology and living organic tissue. "By utilizing technology, you're able to improve your body beyond anything you could do in the past," said Daniel Wilson, an engineer with degrees in machine learning and robotics from Carnegie Mellon University.'

jfruh (300774) writes "Blue River Technology built a robot named LettuceBot that uses computer vision to kill unwanted lettuce plants in a field. Rather than build their creation from scratch, they built off of the Robot Operating System, an open source OS that, in the words of one engineer, 'allowed only a few engineers to write an entire system and receive our first check for service in only a few months.' With ROS robots starting to appear everywhere, including the International Space Station, it looks like open source may be making huge strides in this area."

waderoush (1271548) writes "Hardware is Silicon Valley's new religion. Bits and atoms aren't so different after all, the creed goes; just as the cost and complexity of starting a software company has drastically declined over the last decade, it's now becoming much cheaper and easier to start companies that make physical things. But talk to almost any real hardware company, and you'll discover that the promised land is still some distance away. Sparse, a San Francisco product design startup, learned that the hard way. The company raised $66,000 on Kickstarter for its uber-cool theft-proof bicycle lights, but it took more than a year to deliver the first units to backers, thanks to a string of unforeseen manufacturing and supply-chain snafus. 'We had all the t's crossed and all the i's dotted and still there was a big daily surprise,' says industrial designer Colin Owen, Sparse's co-founder and CEO. Today Sparse is shipping and profitable, with a vision to 'change the face of mobility' for urban cyclists, but its story illustrates just how high the bar still is for aspiring hardware entrepreneurs. Says Owen: 'I wish there was more of a handbook for these things, but the biggest hiccups were very localized and unpredictable.'"

It's a device, and quite a small one, based on the Raspberry Pi. It tells you when the ISS is visible from your part of the world and when it will soon be visible so you can grab the kids and dogs and run outside to wave at the astronauts. Or just to watch the closest thing humanity has to a space colony orbit the Earth. Liam Kennedy, ISS-Above's creator, points out that the ISS passes over most of the inhabited parts of the Earth five or six times a day, which is more than most people know. And about ISS-Above and Kickstarter: It's too late to climb on that wagon, and it already was when this interview was recorded in mid-May. But don't despair. Liam managed to raise $17,731 -- which was far more than his $5000 goal. Can you buy one of these things in its various manifestations? Yes. But you need to look long and hard at the ISS-Above website to spot the all-caps word HERE that takes you to the order page. Liam also points out that you can get all kinds of smartphone apps that will tell you where the ISS is at any given moment, but the ISS-Above has an advantage or two over those apps that will be revealed only to those who watch the video or read the transcript.
