Build Your Own Open-Source SmartWatch

HowTos

If you’re not up for spending your money on one of the less advanced smart watch models, you may want to check out maker Jonathan Cook’s DIY Open-Source SmartWatch, part of which is 3D printed, something the prognosticators of future tech surely didn’t forecast. Cook shared instructions for making his SmartWatch on the webzine “Make:” and also on his own website, DoNothingBox. You can download the STL files on the DNB site, too. For around $125 or less you can make your own smart phone and you can customize it, something that you wouldn’t be able to do with a store-bought version.

Open Source Haptics Kit Aims to Democratize Force Feedback

Filed under
Hardware
OSS

quick terminology dive: a spacial haptic device is a physical manipulator that enables exploration of a virtual space through force feedback. A user grips the “manipulandum” (the handle) and moves it within the work area defined by the physical design of the device. Spacial Haptic Devices have been around for years and serve as excellent tools for telling their users (surgeons) what something (tumor) “feels like.”

In our case, this haptic device is a two-link, two-joint system grounded on a base station and providing force feedback with servo motors and tensioned wire ropes. The manipulator itself supports 3-degree-of-freedom movement of the end-effector (translations, but no rotations) which is tracked with encoders placed on all joints. To enable feedback, joints are engaged with cable-drive transmissions.

BeagleBone SBC beefs up Lego Mindstorms EV3

Hardware

An “EVB” Kickstarter project replaces the Lego Mindstorms EV3 robot’s ARM9 brick with a BeagleBone Black, adding performance, expandability, and sensors.

When Lego added a Linux-based “Brick” computer to its modular, open source Lego Mindstorms robot platform, we were psyched, but were also somewhat disappointed it was only a modest ARM9-based device. Now, a startup called Fatcatlab has found Kickstarter success with an EVB computer you can use in place of the Brick that is designed to plug in a BeagleBone Black for a much faster 1GHz Cortex-A8 experience.

5 favorite Raspberry Pi and Arduino projects

It has never been a better time to understand the components that fit together to make the hardware we use work. To do that, lets look at my five favorite open hardware projects.

First, what do I mean by open hardware? I mean that the components that make up a device are available for the user to see. No secret formulas. The ingredients are completely transparent, and if you chose, you can source the raw parts and assemble them yourself. You can also learn from the process of assembly and with a team spirit share any problems encountered, then improving the formula of the device. For example, you could suggest better parts or improve the code to make it run faster.

Gen-2 SmartThings hub migrates to Linux

Hardware

SmartThings debuted a 2nd generation home automation hub that moves to Linux, and adds new sensors, battery backup, optional cellular, and premium services.

Prior to Samsung’s acquisition of SmartThings last August, the company told us its next-generation home automation hub would likely move from an embedded RTOS (real-time operating system) to Linux. A SmartThings rep now tells us the newly announced second-generation SmartThings Hub does indeed run Linux. Not so surprisingly, consider the Samsung acquisition, the rep also said “We will be moving to Tizen over time.”

This Microsoft Surface lookalike runs a productive version of Android instead

Hardware

At first glance on the CES show floor, the Remix Ultra-Tablet seems like a cheap Surface knock-off. It has a two-stage kickstand similar to that of the Surface Pro 2—albeit one that feels flimsier than Microsoft’s model—and a magnetic keyboard cover with traveling keys and a felt material over the trackpad.

Intel Compute Stick runs Windows and Linux, fits in your pocket

A few months back, I got a breathless email from an Intel PR rep due to some confusion over a little Chinese-made HDMI PC. Now we know why: Intel was stealthily getting ready to launch one of their own.

This tiny black stick emblazoned with the “Intel inside” logo is Intel’s Compute Stick. This device isn’t like the Dell Cloud Connect dongle that they took to CES last year, nor is it a copy of Microsoft’s Wireless Display Adapter. It’s a full PC, capable of running both Linux and Windows, and it’s set to go on sale in the very near future.

  • Open-source developers targeted in sophisticated malware attack
    For the past few months, developers who publish their code on GitHub have been targeted in an attack campaign that uses a little-known but potent cyberespionage malware. The attacks started in January and consisted of malicious emails specifically crafted to attract the attention of developers, such as requests for help with development projects and offers of payment for custom programming jobs. The emails had .gz attachments that contained Word documents with malicious macro code attached. If allowed to execute, the macro code executed a PowerShell script that reached out to a remote server and downloaded a malware program known as Dimnie.
  • A scramble at Cisco exposes uncomfortable truths about U.S. cyber defense
    When WikiLeaks founder Julian Assange disclosed earlier this month that his anti-secrecy group had obtained CIA tools for hacking into technology products made by U.S. companies, security engineers at Cisco Systems (CSCO.O) swung into action. The Wikileaks documents described how the Central Intelligence Agency had learned more than a year ago how to exploit flaws in Cisco's widely used Internet switches, which direct electronic traffic, to enable eavesdropping. Senior Cisco managers immediately reassigned staff from other projects to figure out how the CIA hacking tricks worked, so they could help customers patch their systems and prevent criminal hackers or spies from using the same methods, three employees told Reuters on condition of anonymity.
  • NTPsec: a Secure, Hardened NTP Implementation
    Network time synchronization—aligning your computer's clock to the same Universal Coordinated Time (UTC) that everyone else is using—is both necessary and a hard problem. Many internet protocols rely on being able to exchange UTC timestamps accurate to small tolerances, but the clock crystal in your computer drifts (its frequency varies by temperature), so it needs occasional adjustments. That's where life gets complicated. Sure, you can get another computer to tell you what time it thinks it is, but if you don't know how long that packet took to get to you, the report isn't very useful. On top of that, its clock might be broken—or lying. To get anywhere, you need to exchange packets with several computers that allow you to compare your notion of UTC with theirs, estimate network delays, apply statistical cluster analysis to the resulting inputs to get a plausible approximation of real UTC, and then adjust your local clock to it. Generally speaking, you can get sustained accuracy to on the close order of 10 milliseconds this way, although asymmetrical routing delays can make it much worse if you're in a bad neighborhood of the internet.

    I assume that every permutation of scams will eventually be tried; it is interesting that the initial ones preyed on people's avarice and dishonesty: "I will transfer millions to your bank account, then you share with me" - with subsequent scams appealing to another demographic: "I want to donate a large sum to your religious charity" - to perhaps capture a more virtuous but still credulous lot. Where will it end ?
