The Contrarian Response To Apple’s Need For Encryption

On December 2, 2015, [Syed Rizwan Farook] and [Tashfeen Malik] opened fire at a San Bernardino County Department of Public Health training event, killing 14 and injuring 22. This was the third deadliest mass shooting in the United States in recent memory, and began a large investigation by local, state, and federal agencies. One piece of evidence recovered by the FBI was an iPhone 5C belonging to one of the shooters. In the days and months after the shooting, the FBI turned to Apple to extract data from this phone.

A few days ago in an open letter to customers, [Tim Cook], CEO of Apple, stated they will not comply with FBI’s request to build a backdoor for the iPhone. While the issue at hand is extracting data from an iPhone recovered from the San Bernardino shooting, [Cook] says building a new version of iOS to extract this data would allow the FBI to unlock any iPhone. Needless to say, there are obvious security implications of this request.

Apple does not publish open letters to its customers often. Having one of the largest companies on the planet come out in support of privacy and encryption is nearly unprecedented. There is well-founded speculation this open letter to the public will be exhibit A in a supreme court case. Needless to say, the Internet has gone a little crazy after this letter was published, and rightly so: just imagine how better off we would be if AT&T said no to the NSA in 2002 – [Snowden] might just be another IT geek working for a government contractor.

CalvinThere is a peculiar aspect of public discourse that doesn’t make any sense. In the absence of being able to say anything interesting, some people have just decided to add a contrary viewpoint. Being right, having a valid argument, or even having evidence to support assertions doesn’t matter; being contrary is far more interesting. Look at any comment thread on the Internet, and you’ll find the longest comment chain is the one refuting the parent article. Look up the ratings for a cable news channel. You’ll find the highest rated show is the one with the most bickering. When is the last time you saw something from the New York Times, Washington Post, or LA Times on Facebook or your favorite news aggregator? Chances are, it wasn’t news. It was an op-ed, most likely one that was espousing a view contrary to either public opinion or public policy.

As with any headline event on the Internet, the contrarians have come out of the woodwork. These contrarians are technically correct and exceedingly myopic.

Show Me The Data: Hackaday.io Year #02

Hackaday.io has just turned two today and we couldn’t be more excited about how far we’ve come. What started out as a simple proof-of-concept, inspired by ye-olde idea of a “virtual hackerspace,” has truly evolved into a global playground for some of the best, brightest, and most creative minds you have ever met. It also became a home and the place to spend sleepless nights for many of us on the team, and we’re excited to share a few ideas on where we are headed going forward.

But before we do that, let’s look at some data.

The Data

We’re thrilled to report that over the last two years, Hackaday.io has grown from zero to a 121,158-member strong community, who have together created a total of 9,736 projects. To put this in context, it is more than a two-fold growth from last year’s milestone of 51,838 users / 4,365 projects. And it doesn’t seem to be showing any signs of slowing down.

Projects

Though these “vanity” metrics sure are a nice validation, the number that gets us the most excited is the fact that the 9,731 projects currently on the site have been created by a total 4,966 different users. What’s even better is the fact that 949 projects are a result of collaboration between two or more people. Altogether, a total of 7,170 different users have participated in the creation of the vast body of engineering knowledge currently residing on Hackaday.io.

Sony VTR with replacement foam brushes

Resurrecting A 1960’s VTR With Foam

Nearly fifty years back, Sony launched the DVC-2400, their first consumer grade video camera. This unit weighed in at 10 pounds, and recorded only 20 minutes of footage per reel. It left something to be desired for $1250, or nearly $9000 in today’s dollars.

[NeXT] got his hands on one of these camera kits, and began bringing it back to life. While all the pieces were included, the Video Tape Recorder (VTR), which is used to play back the footage, didn’t power up. A little poking found a dead transistor. After determining a modern replacement part, the voltages checked out. However, the drum still wasn’t spinning.

Further disassembly found that the drum’s DC motor was made on the cheap, using a foam instead of springs to apply pressure on the brushes. This foam had worn out and lost its springy qualities, so no electrical contact was made. New foam was cut out as a replacement. Once reassembled, the drum spun successfully. After some adjustment, the VTR was running at the correct speed once again.

With this working, the VTR should be ready to go. However, camera still isn’t working, so we’re awaiting a part 2.

5D Glass Disc Can Store 360TB!

There’s a small subset of hackers out there concerned with the end of the world. What if our entire existence vanished? How would an alien race learn not to do what we did, what resulted in our demise? We’ve all heard of laser etching metal disks with the Bible, accounts of history, and even just names — pretty sure we’ve sent quite a few into space. But researchers at the University of Southampton’s Optical Research Center have come up with an even superior storage method. They call it the 5D Disc.

According to the researchers, each disc could hold a theoretical 360TB. They can withstand temperatures of up to 1000C, and it’s believe that they could last up to 13.8 billion years at room temperature without degrading — if that’s true, our sun would be long dead before the disc degraded!

TV Control With Hand Gestures

The cell phones of yesteryear were covered in buttons. Today’s cell phones are mostly a touch display with maybe one or two buttons. As time marches on, we find ourselves using our fingers more for gestures and swipes than button pushing to control our devices. Sadly, the television remote has been stuck in an antiquated state and most are still covered in archaic buttons.

[Frederick] has decided to dig the TV remote out from the stone age and updated it to use simple gestures for control. We’ve seen gesture control before, but this one is certainly the most elegant. He’s using a Raspberry Pi with a Skywriter HAT gesture recognition board. The driver is super easy to install and can be done in a single command line. The Skywriter hat interpreters the hand gesture and the Pi fires the appropriate signal via an IR emitter. This approach made the project fairly simple to put together, with surprisingly good results.

Be sure to check out his blog for all code needed, and take a look at the video below to see the remote in action.

All This Bike Needs Is Some Snow!

It’s safe to say that the southern UK is not known for its winter snowfall. If you have lived through a British February then the chances are you’ll know a lot about rain and grey skies.

Happily this hasn’t deterred [Stuart]. Ever the optimist, he’s turned a pile of scrap metal and an unloved mountain bike into a fully functional ski-bike, and he’s just ready to go should the jet stream deliver a covering of the white stuff on the Thames Valley.

Using the facilities of rLab – Reading Makerspsce (he’s also a founder member of the up-and-coming Newbury and District Hackspace), [Stuart] didn’t just bodge together his “iCycle”. Instead he’s made it a really high quality build, with CNC’d aluminium fork stanchions to mount his skis, and foot pegs that are engineered not to let him down on the slopes. Best of all, the bike is nearly all made from scrap materials, only the bearings, axles and paint were brought in for the project.

Skiing hasn’t been featured very often in our coverage of the world of makers, however we have featured a skiing robot, back in 2009.

Musical Shades

There are only so many blinking light patterns you can create with a microcontroller before you get bored. [Garrett] apparently felt that way and decided to build a music-driven LED display on some LED shades. The system has three main elements: a microphone, a preamp, and a 7-band spectrum analyzer chip. You can see the results in the video below.
