Starter Guide to Linux Forensics

Posted on by

The old saying is if your data isn’t backed up at least twice, it’s not backed up at all. For those not wise enough to heed this adage, there are a number of options available to you if you wish your data to be recovered. Assuming the drive itself is just corrupted somehow (maybe a malicious attack, maybe a user error) and not damaged beyond physical repair, the first step is to connect the drive to another computer. If that fails, it might be time to break out the computer forensics skills.

[Luis]’s guide is focused on Linux-specific drives and …read more

Every Digital Yin has a Physical Yang

Posted on by

In the year 1453, the Ottoman Empire under Sultan Mehmed II was able to accomplish what none before them had ever been able to achieve. For more than a millennium, Byzantium had remained a bastion of the Orthodox faith, the great kingdom of the East. The hordes and barbarians that had caused the downfall of […]

Shut Up and Say Something: Amateur Radio Digital Modes

Posted on by

In a recent article, I lamented my distaste for carrying on the classic amateur radio conversation — calling CQ, having someone from far away or around the block call back, exchange call signs and signal reports and perhaps a few pleasantries. I think the idle chit-chat is a big turn-off to a lot of folks who would otherwise be interested in the World’s Greatest Hobby™, but thankfully there are plenty of ways for the mic-shy to get on the air. So as a public service I’d like to go over some of the many digital modes amateur radio offers as …read more

The Enchanting Power Of SDDSbot

Posted on by

Who doesn’t love a good robot? If you don’t — how dare you! — then this charming little scamp might just bring the hint of a smile to your face.

SDDSbot — built out of an old Sony Dynamic Digital Sound system’s reel cover — can’t do much other than turn left, right, or walk forwards on four D/C motor-controlled legs, but it does so using the power of a Pixy camera and an Arduino. The Pixy reads colour combinations that denote stop and go commands from sheets of paper, attempting to keep it in the center of its field …read more

Old Thermometer Gets New Eyes

Posted on by

As much as we’d like to have the right tools for the right job all of the time, sometimes our parts drawers have other things in mind. After all, what’s better than buying a new tool than building one yourself from things you had lying around? That’s at least what [Saulius] must have been thinking when he needed a thermometer with a digital output, but only had a dumb, but feature-rich, thermometer on hand.

Luckily, [Saulius] had a webcam lying around as well as an old thermometer, and since the thermometer had a LCD display it was relatively straightforward to …read more

Super Bowl “Digital Deflategate” is Not Just Air

Posted on by

When we think of large entertainment venues and events, it’s not just ticket fees and concessions anymore. Sporting is entertainment and this year’s Super Bowl LI (51) is one of the most complex, technologically orchestrated events in the world; ranging from tablet-based play books to RFID wearable sensors on players sending real time performance data…

Big Brother and Others Are Watching Your Car

Posted on by

We are all (hopefully) aware that we can be watched while we’re online. Our clicks are all trackable to some extent, whether it’s our country’s government or an advertiser. What isn’t as obvious, though, is that it’s just as easy to track our movements in real life. [Saulius] was able to prove this concept by using optical character recognition to track the license plate numbers of passing cars half a kilometer away.

To achieve such long distances (and still have clear and reliable data to work with) [Saulius] paired a 70-300 mm telephoto lens with a compact USB camera. All …read more
