Thrift Store Hard Drive Enclosure

May 2, 2011 by 8 Comments

[Ken] visited our site looking for case modding stuff a little while back, but more importantly he came back to show off his latest project. Using a jewelry box found at our favorite place, the thrift store, he converted it into a 2.5 inch USB drive enclosure.

Almost instantly he found that this particular jewelry box is a perfect fit for a 2.5 inch SATA laptop drive. Taking that as a sign he whipped up some acrylic mounts and cut some holes for power and USB . The electronics are provided by another enclosure with a dead drive, again acrylic is used to insulate the drive from the decorative metal box and some rubber washers were used to help cancel out vibrations and noise.

The end result is a classy looking 150gig usb drive that looks nice on the desk, and a little reminder that if your not hitting up your local thrift / second hand stores, you could be missing out on some real gems.

Scout, The Autonomous Transatlantic Boat

Sailing a small boat across the Atlantic ocean is quite the daunting task. As many have discovered, it is a journey often fraught with perils, typically ending in failure. A team of four college students decided the best way to get a small boat across the ocean would be to remove the human element from the process, so they set off to build an autonomous craft to take on the task.

Like most projects, this one started as a handful of wild ideas exchanged between friends [Dylan Rodriguez and Max Kramers]. As they thought about it more, they decided that turning [Max’s] sailboat into an autonomous ocean-going craft would be pretty awesome, so they got to work. Recruiting help from their friends [Brendan Prior and Ricky Lyman], the project started to quickly take shape, and Scout was born.

Scout is 8 feet long and consists of foam core covered in carbon fiber. It is filled with various electronic components such as a SPOT tracker, a battery bank that will power the boat for up to 25 hours, and the various servos and motors which will be used to pilot the craft.

It’s a rather ambitious project, though the boat is nearly complete – just in time for their launch, slated for May 29th. We’ll certainly be keeping an eye on this project as the launch date approaches – good luck guys!

Head on over to their Kickstarter page to see a promo video introducing Scout.

3D Printed Strandbeests Made To Order

strandbeest

If you love Strandbeests but don’t have the patience to build your own, Dutch artist [Theo Jansen] has you covered. You might remember him from a story we ran last year, detailing his awesome beach-going strandbeest creations.

His beach walkers are typically built out of PVC conduit and plastic tubing, towering over their creator. For the time being however, he is focusing his work on a much smaller scale. [Theo] has recently teamed up with a 3D printing shop in order to offer miniature working replicas of his creations to the public. The current models can be had for $105, which seems like a pretty steep price to us. Then again, these models come fully assembled and are composed of 76 individual pieces, which is nothing to sneeze at.

That said, considering how easily a Strandbeest can be created with a stack of thick paper and some free time, we imagine that an enterprising individual could build one using readily available plastics at a fraction of the cost. Anyone out there up for giving it a shot?

Isolation Transformer 101

May 2, 2011 by 23 Comments

[Todd Harrison] has released a ~50 minute video covering everything you want to know about Isolation Transformers for protecting yourself and your costly equipment. Admittedly I have not given the subject much thought, but if you need to measure high voltages you should probably watch this video.

[Todd] Explains the differences between different types of transformers, including cost, why you would want one, safety and plenty of theory. Whiteboard in hand, all the details are clearly explained. If that’s not enough to convince you, there are some fun “don’t try this at home” experiments that hit the point home.

He has a pretty beefy 8 amp 40 lb monster that cost a fairly large amount, though its worth it to be safe. Unless you think you’re going to need that type of amperage, you wold probably be fine with a smaller model. The product shown in the video is a hospital grade, and requires a mod to make it safe for your bench. [Todd] explains that mod as well. Even if your not planning to do this, its still cool to see a transformer bigger than your hand. Plus it makes a pretty cool sound.

Join us after the break for the video.

Flinging Birds And Slaying Pigs With Your Thoughts

May 2, 2011 by 28 Comments

angry_birds_mind_control

[Rafael Mizrahi and Anat Sambol] decided that Angry Birds was missing one crucial element – mind control. They grabbed a copy of the game for their netbook and [Rafael] strapped on an Emotiv EPOC headset to see if he could play it without using a mouse or keyboard. While he was able to move the cursor around with his thoughts, he found that Emotiv’s EmoKey software lacked any sort of mouse button support. Undaunted, they turned to the Internet for help and found that he could map the Emotiv’s output to his mouse via another application, GlovePie.

As you can see in the video below their efforts were successful, though we doubt [Rafael] will be completely giving up his mouse just yet. With some more refinement, we imagine [Rafael] will be blasting pigs to kingdom come in no time.

If you are interested in trying this yourself, be aware that only the SDK version of the EPOC headset can be paired with 3rd party applications, the standard consumer version is locked into using solely authorized software.

Papercraft Strandbeest Is A Great Rainy Day Project

May 1, 2011 by 6 Comments

Here in the Midwest it sometimes seems like Spring will never, well…spring. We get that “April showers bring May flowers”, but nearly all of the last month has been cold and rainy around these parts. While things are improving, we think it’s always good practice to have a few fun projects at the ready, just in case your plans with the kids get rained out.

We think that Hackaday reader [Dombeef’s] papercraft strandbeest is a perfect idea for a rainy afternoon. The supply list is pretty short, requiring little more than some scissors, pliers, paperclips, and glue in addition to the thick paper that makes up the body of the strandbeest. The paper is cut into pieces according to the PDF template he includes in his Instructable, secured to one another via small pieces of paperclip.

Once the legs are all constructed, a main axis is built from one of the remaining paperclips, and everything is joined together under the main portion of the strandbeest’s body.

As you can see in the video, the legs work quite well, though the strandbeest can probably benefit from a hand crank in the short term. [Dombeef] plans on adding a small motor to his creation, which should get the strandbeest moving about quite rapidly once completed.

If you are looking for more fun projects to do with the kids, look no further than this papercraft gyroscope or these squishy circuits.

Racing Wheel Guided R/C Car With Video Feed

May 1, 2011 by 12 Comments

Instructables user [Kaeru no Ojisan] enjoys constructing R/C kit cars and wanted to build one that could be driven using a PC racing wheel he had on hand. Not satisfied with simply guiding it with the racing wheel, he added a web cam to the car so that he can monitor its location from the comfort of his desk chair.

The car is loaded down with all sorts of electronics to get the job done, requiring four separate battery packs to keep them online. An Arduino controls the motor and the steering servos, receiving its commands wirelessly via a Bluetooth add-on. The camera connects to a USB to Ethernet converter, which enables the car’s video feed to be transmitted via the onboard wireless router.

The racing wheel interface seems to work just fine, though we don’t doubt that the whole setup can be easily simplified, reducing both weight and battery count. While [Kaeru no Ojisan] says that the car is in its concept stages and there are a few bugs to work out, we think it’s a good start.

Stick around to see a quick video of the car in testing.
