Raspberry Pi 2 vs Creator 120

Filed under

Hardware
Reviews

The Creator 120 and the Raspberry Pi 2 are single-board computers designed for developers and hobbyists.

The Creator C120 was announced in late 2014, but started shipping at about the same time that the Raspberry Pi 2 was announced/starting shipping, which was just last week.

I haven’t purchased a Raspberry Pi 2 yet, but I received a Creator 2 from the manufacturer this week. It was a prize I won in December and the first prize I ever won on the Internet. I’ve been playing with it all day and find it to be a very capable single-board computer. Out of the box, it’s mostly a plug-and-play device.

Review: 2015 Dell XPS 13 (9343) Running Linux

Filed under
Hardware
Reviews

When and if Eric reads this he’s just going to shake his head. For two years in a row now I’ve been lured by the wonders of new laptops announced at CES, and in both years I’ve been disappointed. He tells me I’m stupid for ordering the “new shiny” and expecting it to work, but I refuse to give up my dream.

Luckily this isn’t a huge issue for me since my main machines are desktops, but my second generation Dell XPS 13 “sputnik” is getting a little old. I am really looking forward to a slightly larger screen. The pixel density isn’t great on my laptop, especially compared to what is out now, and I am finding myself a little cramped for screen real estate.

Attention Linux gamers: Valve, Khronos to reveal next-gen OpenGL successor at GDC

Gaming

It's a great time to be alive if you're a fanatic about the particulars of various performance-boosting graphics APIs. AMD's Mantle is here, Microsoft's DirectX 12 is coming with Windows 10, and at GDC in early March we'll hear the first news about a successor to the open-source, cross-platform OpenGL API.

That's not necessarily huge news if you're using a Windows machine—unless this OpenGL successor is really special, most games will probably stick with DirectX 12 in a perpetual love/hate relationship. If you're a Mac or Linux gamer, however, the next-generation OpenGL is potentially a huge deal.

Hands-On: RaspberryPi NOOBS 1.3.12

Hardware
Reviews

There's plenty of excitement in the Raspberry Pi world this week: the big news is the announcement of the Raspberry Pi 2 hardware - the long-awaited and much-anticipated successor to the immensely popular original unit, which will now be known as the Raspberry Pi 1.

But that's not the only news: there is also a new release of the Raspbian operating system and the NOOBS (New Out Of Box Software) package. I am just back from a week in Amsterdam, and will be leaving in a few days for a short trip to Iceland, so I just have time to download and install the new software on my two Raspberry Pi 1 units (Model B and B+), and I have ordered a RPi 2 so I hope that will be waiting for me when I return. At least, the Swiss Pi-Shop says that it will be available on 3 February so I am keeping my fingers crossed - because almost all of the excitement is about the Raspberry Pi 2.

CuBox-i4Pro Review

Hardware

A bundled microSD card arrives preinserted into the rear of the CuBox-i, and it’s loaded with a version of Google’s Android operating system. Interestingly, SolidRun has gone to the effort of seeking the certifications required to load the Google Apps suite onto the card, meaning users receive Google Mail, YouTube, Google Maps and full access to Google Play straight out of the box. An even newer build, based on the latest Android 4.4 KitKat branch, can be downloaded from SolidRun’s website and provides an entirely useable desktop Android experience.

AMD FX-8320E Performance On Linux

Back in September AMD announced new FX CPUs that included the FX-8370, FX-8370E, and FX-8320E. Back then we reviewed the FX-8370/FX-8370E CPUs under Linux but at the time didn't have our hands on the more affordable FX-8320E processor. In December AMD sent over the FX-8320E and so for the past few weeks I've been happily using this new Vishera CPU.

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

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

Hardware

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.

10 beautiful Android Wear watch face packs

Unlike a smartwatch, A high-quality traditional watch doesn't need to be recharged on a daily basis. Also, it will likely be perfectly useful decades after its purchase, while a smartwatch isn't likely to endure the tests of time very well. But can you change a classic watch's face? Nope, we don't think so. The ability to personalize an Android Wear smartwatch is cool indeed, and the collection of third-party watch faces available at the Play Store is growing steadily. Some are functional and feature-packed, others aim to deliver the best visual experience. The 10 Android Wear watch face packs we have below belong to the latter category. Check them out! Read more
