Helicopter Parts Make For Amazing DIY Camera Stabilization 78

Posted by timothy
from the so-you'll-be-checking-luggage-then dept.
Iddo Genuth writes "Videographer Tom Antos developed an advanced DIY camera stabilizer which can hold almost any DSLR or mirrorless camera steady for video photography. Although this surely isn't as sophisticated (and super expensive) as the professional MVI M10 handheld 3-axis digital stabilized camera gimbal, its still quite impressive especially when you consider it only costs a few hundred dollars rather then tens of thousands — that is if you feel like building it yourself." Antos' design takes advantage of stabilized gimbal systems made for hanging cameras on remote-controlled helicopters, and does a very impressive job for its price.

Retro Gaming With Raspberry Pi 106

Posted by Soulskill
from the bring-your-own-roms dept.
coop0030 writes "Thanks to the affordable Raspberry Pi and some clever software, anyone can re-create the classic arcade experience at home. Adafruit brings the genuine 'clicky' arcade controls, you bring the game files and a little crafting skill to build it. Classic game emulation used to require a well-specced PC and specialized adapters for the controls, so it's exciting to see this trickle down to a $40 system. Also, a video of the game system is on YouTube."

vinces99 writes "Forget to turn off the lights before leaving the apartment? No problem. Just raise your hand, finger-swipe the air and your lights will power down. Want to change the song playing on your music system in the other room? Move your hand to the right and flip through the songs. University of Washington computer scientists have developed gesture-recognition technology that brings this a step closer to reality. They have shown it's possible to use Wi-Fi signals around us to detect specific movements without needing sensors on the human body or cameras. By using an adapted Wi-Fi router and a few wireless devices in the living room, users could control their electronics and household appliances from any room in the home with a simple gesture."

Pi to Go: Hot Raspberry Pi DIY Mini Desktop PC Project 134

Posted by timothy
from the tab-a-slot-b-fruit-x dept.
MojoKid writes "Hot Hardware recently set out to design a custom mini desktop system with the popular Raspberry Pi single board computer. People have configured the device for a variety of applications, from micro-servers to low cost media players. Basically, the goal was to turn what is currently one of the cheapest bare-bones computer boards into a fully enclosed mini desktop computer that could be taken anywhere without the need for cabling or setup. This small DIY project is just one of many examples of the flexibility of the Raspberry Pi's open architecture. And to think you can even run Quake and Minecraft on it."

Canon DSLR Hack Allows It To Shoot RAW Video 171

Posted by Soulskill
from the features-added-by-users dept.
When the Canon 50D DSLR camera was released back in 2008, it could take nice pictures, but it had no support for video recording. Now, through an enterprising hack by members of the Magic Lantern forums, the 50D can capture RAW video. From the article: "The tech inside the 50D looks like it borrows a lot more from its higher-end siblings, like the 5D Mark II, and it’s possible we may actually get better RAW video quality out of the 50D than we do out of any of the non-CF Canon cameras. ... The camera doesn’t have playback or audio recording as it was never designed to shoot video, but this isn’t too different from the RAW recording on the other Canon DSLRs at the moment."

Vastly Improved Raspberry Pi Performance With Wayland 259

Posted by Unknown Lamer
from the fast-and-fancy dept.
New submitter nekohayo writes "While Wayland/Weston 1.1 brought support to the Raspberry Pi merely a month ago, work has recently been done to bring true hardware-accelerated compositing capabilities to the RPi's graphics stack using Weston. The Raspberry Pi foundation has made an announcement about the work that has been done with Collabora to make this happen. X.org/Wayland developer Daniel Stone has written a blog post about this, including a video demonstrating the improved reactivity and performance. Developer Pekka Paalanen also provided additional technical details about the implementation." Rather than using the OpenGL ES hardware, the new compositor implementation uses the SoC's 2D scaler/compositing hardware which offers "a scaling throughput of 500 megapixels per second and blending throughput of 1 gigapixel per second. It runs independently of the OpenGL ES hardware, so we can continue to render 3D graphics at the full, very fast rate, even while compositing."

Ask Slashdot: Wiring Home Furniture? 235

b1tbkt writes "So it seems that furniture manufacturers have not yet acknowledged the realities of modern life. Kitchen tables could benefit greatly from built-in concealable receptacles. Even more obvious is the need for electrical wiring in couches and coffee tables. I realize that there are safety (fire) concerns but as it stands most families that I know already have power cords for laptops, tables and phones draped over, under and through their couches at any given point. If someone wanted to wire their furniture with AC or some type of standardized LV DC system, what are some dangers to watch for and what, if any, specialized hardware exists for the purpose?"

Arduino Branches Out, With a Plug-and-Program Robot 24

Posted by timothy
from the roll-'em dept.
mikejuk writes "The new Arduino robot looks a bit like a robot vacuum cleaner, but it has a lot more going for it and it certainly doesn't suck — well not unless you add an air pump to it. As always, the Arduino Robot is completely open source and comes as an easy to assemble kit involving no soldering, just some plugging in of components. It consists of two circular boards, 19cm in diameter, each with its own Arduino controller. They fit together to create a stack about 10cm tall. The bottom board has two wheels and motors which allow it to move in any direction. The top board contains lots of sensors and a central display. The two communicate via a serial connection. There is also a lot of space for expansion. There is a new library which can be downloaded to help write programs for this fairly sophisticated robot. There is only one big problem with the Arduino robot — you can't buy one at the moment. If you really can't wait, until early July when they should start shipping from the Arduino shop and from distributors, then you will have to get to the Maker Faire San Mateo (May 17-19) where they are being demonstrated and sold."

RPiCluster: Another Raspberry Pi Cluster, With Neat Tricks 79

Posted by timothy
from the dots-dots-blinkenlights dept.
New submitter TheJish writes "The RPiCluster is a 33-node Beowulf cluster built using Raspberry Pis (RPis). The RPiCluster is a little side project I worked on over the last couple months as part of my dissertation work at Boise State University. I had need of a cluster to run a distributed simulator I've been developing. The RPiCluster is the result. I've written an informal document on why I built the RPiCluster, how it was built, and how it performs as compared to other platforms. I also put together a YouTube video of it running an MPI parallel program I created to demo the RGB LEDs installed on each node as part of the build. While there have certainly been larger RPi clusters put together recently, I figured the Slashdot community might be interested in this build as I believe it is a novel approach to the rack mounting and power management of RPis."

hypnosec writes with word that the OpenWRT team a few days ago released the final version of the project's newest iteration, version 12.09 (codenamed "Attitude Adjustment"). "The final version doesn't support Linux 2.4, because of which the distribution wouldn't run on old router models, for example the Linksys WRT54G models, which have 16MB of RAM and CPUs clocked at 200MHz. The distribution is now based on Linux 3.3 and there is good news for the Raspberry Pi fans as the distribution now supports the credit card-sized computer, along with Ramips routers."

$5 Sensor Turns LCD Monitors Into Touchscreens 98

Posted by timothy
from the later-comes-the-voice-control dept.
An anonymous reader writes with this snippet from ExtremeTech: "Researchers at the University of Washington's aptly named Ubiquitous Computing Lab can turn any LCD monitor in your house into a touchscreen, with nothing more than a $5 sensor that plugs into the wall and some clever software." The system works by measuring changes that your hand creates in the electromagnetic signature of the monitor. Surprisingly, it offers some pretty fine-grained detection, too: "full-hand touch, five-finger touch, hovering above the screen, pushing, and pulling." The "$5 sensor" part is mostly theoretical for now to those of us who don't live in a lab, though; on the other hand, "co-author Sidhant Gupta tells Technology Review that the $5 sensor uses off-the-shelf parts, and the algorithms are included in the paper, so it would be fairly easy for you — or a commercial entity — to recreate the uTouch system."

Happy Hardware Freedom Day 35

Blug_fred writes "For the first year the Digital Freedom Foundation (ex-SFI) is organizing Hardware Freedom Day. With 66 events worldwide split over 36 countries, they are not yet covering the whole world but it is a good start. So if you have always been wondering about hacking your own stuff, be it a piece of wood or some more complex electronic gears then it is time to join an open door day type of event. Sixty-six events is definitely less that the total number of hackerspaces around the world and you can check for other events happening in a hackerspace near you if none are celebrating today. Hopefully they will join the movement next year."

The Hacker Lifecycle 77

Posted by Soulskill
from the pollination-fertilization-budding-and-dispersal dept.
An anonymous reader writes "Hacker Benjamin Smith deconstructs the cycle of education, production, and rest that will be familiar to many software and hardware engineers. He breaks it down into four steps: 1) Focused effort toward a goal, 2) structured self-education, 3) side-projects to sharpen skills, and 4) burnout and rest. He writes, 'As my motivation waxes at the beginning of a cycle, I find myself with a craving to take steps towards that goal. I do so by starting a project which focuses on one thing only: building a new income stream. As a result of this single-mindedness, the content or subject of the project is often less interesting than it otherwise might have been. ... [Later], I almost always decide to teach myself a new technical skill or pick up some new technology. ... This is usually the most satisfying period of my cycle. I am learning a new skill or technology which I know will enhance my employability, allow me to build things I previously could only have daydreamed about, and will ultimately be useful for many years to come. ... [In the burnout phase], I'll spend this period as ferociously devoted to my leisure activities as I was to my productive tasks. But after a few months of this, I start to feel an itch...'"

I fixed them up, and now they run Lubuntu fairly well, making them great internet/LibreOffice/general Linux workstations. I've been wanting to donate them to local nonprofits where they'll go to good use — for example, I've already given several to a local church for them to use in their afterschool care/tutoring program. However, I'm having trouble finding other places where these machines could go to good use. How should I best conduct this search? How can I find nonprofits that could benefit from these workstations?"

yenrabbit writes "A friend has just told me he has 80 CRT TVs, a stack of DVD players and hundreds of VCR machines, all broken and all mine free of charge. I can already think of a few awesome components I can extract (flyback transformers for high voltage contraptions and so on) and have a few ideas, such as DVD lasers, that I can build. But what else can be made from such a treasure-trove of components, and how would one go about processing such a large volume of stuff with the least amount of effort? Also, I don't have access to online shopping so I'd also like a pain free way of salvaging many simpler parts such as resistors as well." Another reader sent in a similar question: "The other day I went down to my University's property disposition center for the first time. In addition to mundane things like chairs and desks, it also had a wealth of technological devices, from old PCs and monitors to obscure medical and chemistry equipment. Honestly, I was a bit overwhelmed. I just don't know what I'd do with a old gene sequencing machine or a broken oscilloscope. Any ideas for fun projects? Or better yet, suggestions on how I can figure out which machines (or their components) are worth playing with?"
