FIDO2 Authentication In All The Colors

October 16, 2018 by 14 Comments

Here at Hackaday, we have a soft spot for security dongles. When a new two-factor-authentication dongle is open source, uses USB and NFC, and supports FIDO2, the newest 2FA standard, we take notice. That just happens to be exactly what [Conor Patrick] is funding on Kickstarter.

We’ve looked at [Conor]’s first generation hardware key, and the process of going from design to physical product.  With that track record, the Solo security key promises to be more than the vaporware that plagues crowdfunding services.

Another player, Yubikey, has also recently announced a new product that supports FIDO2 and NFC. While Yubikey has stepped away from their early open source policy, Solo is embracing the open source ethos. The Kickstarter promises the release of both the software and hardware design as fully open, using MIT and CC BY-SA licenses.

For more information, see the blog post detailing the project goals and initial design process.  As always, caveat emptor, but this seems to be a crowdfunding project worth taking a look at.

Hams See Dark Side Of The Moon Without Pink Floyd

October 15, 2018 by 36 Comments

Ham radio operators bouncing signals off the moon have become old hat. But a ham radio transmitter on the Chinese Longjiang-2 satellite is orbiting the moon and has sent back pictures of the Earth and the dark side of the moon. The transceiver’s main purpose is to allow hams to downlink telemetry and relay messages via lunar orbit.

While the photo was received by the Dwingeloo radio telescope, reports are that other hams also picked up the signal. The entire affair has drawn in hams around the world. Some of the communications use a modulation scheme devised by [Joe Taylor, K1JT] who also happens to be a recipient of a Nobel prize for his work with pulsars. The Dwingeloo telescope has several ham radio operators including [PA3FXB] and [PE1CHQ].

Flash: Arduino Vidor FPGA Instructions Hit France

October 14, 2018 by 12 Comments

If you speak French and you have an Arduino Vidor 4000, you are in luck because there’s some good news. The good news is there’s finally some inside information about how to configure the onboard FPGA yourself. The bad news though is that it is pretty sparse. If your high school French isn’t up to the task, there’s always Google Translate.

We knew some of this already. You’ll need Quartus, the FPGA design tool from Altera — er, Intel — and we know about the sample project on GitHub, too. Instead of using conventional Verilog or VHDL, the new information uses schematic capture, but that’s OK. All the design entry winds up in the same place, so it should be easy to adapt to the language of your choice. In fact, in part 2 they show both some schematics and some Verilog. Google Translate does have a little trouble with code comments, though. If you want something even stouter, there’s an example that uses Verilog to output a video frame.

Mergers And Acquisitions: Apple Buys Most Of Dialog

October 13, 2018 by 16 Comments

Apple is buying a $600 million stake in Dialog Semiconductor in a deal Dialog is describing as an asset transfer and licensing deal.

Dialog’s current portfolio is focused mainly on mobile devices, with Bluetooth wearables-on-a-chip, CODEC chips for smartphones, and power management ICs for every type of portable electronics. Power managment ICs are by far the most visible component, although they do have the very interesting GreenPAK, a sort of mixed-signal FPGA-ish thing that is one of the more interesting chips to be come online in the last few years. Apple of course are a trillion dollar company that once made computers, but now receives most of its revenue through phone dongles and lightning connector converters. It is not clear at the time of this writing whether a Dialog engineer with experience in heat management will be joining Apple.

In the last week, Apple have taken some bad press about the state of their supply chain. Bloomberg reported Apple found hidden chips in Supermicro motherboards. ostensibly implanted by Chinese intelligence agencies. This story is reportedly multiply sourced, but there’s no evidence or explanation of how this supply chain hack was done. In short, infiltration of a supply chain by foreign agents could happen (and I suspect Bloomberg engineers found something in some of their hardware), but the Bloomberg piece is merely just a wake-up call telling us yes, you are vulnerable to a hardware attack.

This is further evidence of Apple’s commitment to vertical integration. Apple are making their own chips, and the A12 Bionic in the new iPhone X is an Apple-designed CPU, GPU, and ‘neural engine’ that turns your Facetime sessions into animated emojis. This chip is merely the latest in a series of SoCs developed by Apple, and adds to Apple’s portfolio of chips designed to run the Apple Watch, Apple AirPods, and system management controllers in Apple products. There’s no other electronics manufacturer that is as dedicated to vertical integration as Apple (although we’re pouring one out for Commodore), and the acquisition of Dialog will surely add to Apple’s capabilities.

Soyuz Rocket Emergency Landing, Everyone OK

October 11, 2018 by 38 Comments

NASA spokesperson [Brandi Dean] summarized it succinctly: “Confirming again that today’s Soyuz MS10 launch did go into ballistic re-entry mode … That means the crew will not be going to the ISS today. Instead they will be taking a sharp landing, coming back to earth”. While nobody likes last-minute changes in plans, we imagine that goes double for astronauts. On the other hand, it’s always good news when we are able to joke about a flight that starts off with a booster separation problem.

Astronauts [Nick Hague] and [Aleksey Ovchinin] were on their way this morning to the International Space Station, but only made it as far as the middle of Kazakhstan. Almost as soon as the problem occurred, the rocket was re-pathed and a rescue team was sent out to meet them. Just an hour and a half after launch, they were on-site and pulled the pair out of the capsule unharmed. Roscosmos has already commissioned a report to look into the event. In short, all of the contingency plans look like they went to plan. We’ll have to wait and see what went wrong.

Watching the video (embedded below) the only obvious sign that anyone got excited is the simultaneous interpreter stumbling a bit when she has to translate [Aleksey] saying “emergency… failure of the booster separation”. Indeed, he reported everything so calmly that the NASA commentator didn’t even catch on for a few seconds. If you want to know what it’s like to remain cool under pressure, have a listen.

Going to space today is still a risky business, but thankfully lacks the danger factor that it once had. For instance, a Soyuz rocket hasn’t had an issue like this since 1975. Apollo 12 was hit by lightning and temporarily lost its navigation computer, but only the truly close call on Apollo 13 was made into a Hollywood Blockbuster. Still, it’s worth pausing a minute or two to think of the people up there floating around. Or maybe even sneak out and catch a glimpse when the ISS flies overhead.

This Year’s Nobel Prizes Are Straight Out Of Science Fiction

October 10, 2018 by 22 Comments

In the 1966 science fiction movie Fantastic Voyage, medical personnel are shrunken to the size of microbes to enter a scientist’s body to perform brain surgery. Due to the work of this year’s winners of the Nobel Prize in Physics, laser tools now do work at this scale.

Arthur Ashkin won for his development of optical tweezers that use a laser to grip and manipulate objects as small a molecule. And Gérard Mourou and Donna Strickland won for coming up with a way to produce ultra-short laser pulses at a high-intensity, used now for performing millions of corrective laser eye surgeries every year.

Here is a look at these inventions, their inventors, and the applications which made them important enough to win a Nobel.

Printrbot Post Mortem

October 10, 2018 by 48 Comments

For many people, Printrbot was their first 3D printer. What started out as [Brook Drumm’s] Kickstarter idea to make 50 printers turned into over a thousand orders backlogged. To quote [Brook], they went from zero sales to about two million in the first year and then twelve million a few years later. As is often the case, though, the rapid scale-up didn’t survive a drop in sales. [Thomas Sanladerer] has a great interview video with [Brook] and you can see it below.

It is both nostalgic and sad to see the Printrbot headquarters all empty with quiet machines. [Brook] was always one of us and often gave back to the community and it is interesting to hear his perspective about what brought his company to an end.
