[Jason] has been playing around with the Oculus Rift lately and came up with a pretty cool software demonstration. It’s probably been done before in some way shape or form, but we love the idea anyway and he’s actually released the program so you can play with it too!
It’s basically a 3D Windows Manager, aptly called 3DWM — though he’s thinking of changing the name to something a bit cooler, maybe the WorkSphere or something.
As he shows in the following video demonstration, the software allows you to set up multiple desktops and windows on your virtual sphere created by the Oculus — essentially creating a virtual multi-monitor setup. There’s a few obvious cons to this setup which makes it a bit unpractical at the moment. Like the inability to see your keyboard (though this shouldn’t really be a problem), the inability to see people around you… and of course the hardware and it’s lack of proper resolution. But besides that, it’s still pretty awesome!
In the future development he hopes to add Kinect 2 and Leap Motion controller integration to help make it even more user intuitive — maybe more Minority Report style.

The Oculus Rift and all the other 3D video goggle solutions out there are great if you want to explore virtual worlds with stereoscopic vision, but until now we haven’t seen anyone exploring real life with digital stereoscopic viewers. [pabr] combined the Kinect-like sensor in an ASUS Xtion with a smartphone in a Google Cardboard-like setup for 3D views the human eye can’t naturally experience like a third-person view, a radar-like display, and seeing what the world would look like with your eyes 20 inches apart.
[pabr] is using an ASUS Xtion depth sensor connected to a Galaxy SIII via the USB OTG port. With a little bit of code, the output from the depth sensor can be pushed to the phone’s display. The hardware setup consists of a VR-Spective, a rather expensive bit of plastic, but with the right mechanical considerations, a piece of cardboard or some foam board and hot glue would do quite nicely.
[pabr] put together a video demo of his build, along with a few examples of what this project can do. It’s rather odd, and surprisingly not a superfluous way to see in 3D. You can check out that video below.

After a hard Saturday at World Maker Faire, some of the best and brightest in the Hacker/Maker community descended on The Holiday Inn for “Bring A Hack”. Created by [Jeri Ellsworth] several years ago at the Bay Area Maker Faire, Bring A Hack (BAH) is an informal gathering. Sometimes a dinner, sometimes a group getting together at a local bar, BAH is has just one rule: You have to bring a hack!
[Sophi Kravitz] has become the unofficial event organizer for BAH in New York. This year she did a bit of live hacking, as she converted her Wobble Wonder headgear from wired to wireless control.
[Chris Gammell] brought his original Bench BudEE from Contextual Electronics. He showed off a few of his board customizations, including making a TSSOP part fit on the wrong footprint.
[Windell and Lenore] from Evil Mad Scientist Laboratories brought a few hacks along. They picked up an old Radio Shack music player chip at the Electronics Flea Market and built it up on a breadboard. Also on display was their new EggBot Pro. The Pro is a beautifully machined version of the eggbot. Everything is built strong to withstand the sort of duty an EggBot would see at a hackerspace or public library. [Windell] was full of surprises, as he also gave everyone chunks of Sal Ammoniac, which is a great way to bring the tin back to a tired soldering iron tip. The hack was that he found his Sal Ammoniac at a local Indian grocery in the Bay Area. Check out [Windell’s] blog entry for more information.
[Cal Howard] brought his DIY VR goggles. [Cal] converted a Kindle Fire into an Oculus Rift style head mounted display by adding a couple of magnifying lenses, some bamboo kebab sticks to hold the lenses in place. Judicious use of cardboard and duct tape completed the project. His current hurdle is getting past the Fire’s lack of an accelerometer. [Cal] planned to spend Sunday at Maker Faire adding one of his own!
As the hour grew late, everyone started to trickle out. Tired but happy from a long day at Maker Faire, the Bring A Hacker partygoers headed back to their hotels to get some sleep before World Maker Faire’s final day.
Oculus, as we know, was acquired by Facebook for $2 billion, and now the VR community has been buzzing about trying to figure out what to do with all this newly accessible technology. And adding to the interest, the 2nd iteration of the development kits were released, causing a resurgence in virtual reality development as computer generated experiences started pouring out from of every corner of the world. But not everyone can afford the $350 USD price tag to purchase one of these devices, bringing out the need for Do-It-Yourself projects like these 3D printed wearable video goggles via Adafruit.
The design of this project is reminiscent of the VR2GO mobile viewer that came out of the MxR Lab (aka the research environment that spun out Palmer Lucky before he created Oculus). However, the hardware here is more robust and utilizes a 5.6″ display and 50mm aspheric lenses instead of a regular smart phone. The HD monitor is held within a 3D printed enclosure along with an Arduino Micro and 9-DOF motion sensor. The outer hood of the case is composed of a combination of PLA and Ninjaflex printing-filament, keeping the fame rigid while the area around the eyes remain flexible and comfortable. The faceplate is secured with a mounting bracket and a pair of aspheric lenses inside split the screen for stereoscopic video. Head straps were added allowing for the device to fit snugly on one’s face.
At the end of the tutorial, the instructions state that once everything is assembled, all that is required afterwards is to plug in a 9V power adapter and an HDMI cable sourcing video from somewhere else. This should get the console up and running; but it would be interesting to see if this design in the future can eliminate the wires and make this into a portable unit. Regardless of which, this project does a fantastic job at showing what it takes to create a homemade virtual reality device. And as you can see from the product list after the break, the price of the project fits under the $350 DK2 amount, helping to save some money while still providing a fun and educational experience.

A ton of people sent in this video of crazy Russians who have taken a microwave, removed the magnetron, taped it to a broom, and turned it on. Don’t try this at home. Or near us.
You know the Google Cardboard kit that’s a real VR headset made of cardboard (and a smart phone)? Google may have gotten their inspiration from Oculus, because every Oculus Rift DK2 ships with a Samsung Galaxy Note 3 inside.
Ever design a PCB and be disappointed by the quality of the silkscreen? [Paul Allen] has been defining the edges of his PCB labels with the copper layer, and the examples are dramatic. Etching copper is what you actually pay for when you fab a board, so it should come as no surprise that the quality is a little higher.
Dunk tanks are fun, but how about competitive dunk tanks? [Chad] built a dunk tank (really more of a ‘dunk shower’) out of a 2×4 tripod, a garbage can, and a few parts from a the toilet aisle of Home Depot’s plumbing department. Then he built a second. Set up both dunk showers across from each other, give two people a few balls, and see who gets soaked last. Looks fun.
Want a MAME cabinet, but don’t want it taking up room in your house? Build a MAME coffee table! Here’s the reddit thread. Maybe we’re old-fashioned, but we’d rather have a giant NES controller coffee table.
Last week we saw a 16-bobbin rope braiding machine, but odd braiding machines like this aren’t limited to fibers. Here’s a wire twisting machine for making RS422 cables. It only produces a single twisted pair, but that’s really all you need to create a cable. Somebody get some paracord and make some Cat5.
Here’s a really clever use for the Oculus Rift — Ecstatic Computation, a virtual reality spirit journey.
[Michael Allison] began his university career as an artist and musician… and somehow down the line, became a Technoshaman. His thesis, presented at ITP 2014, is on computational art, virtual reality, cognitive psychology and his research on various religious, spiritual and scientific methods that try to explain the relationship between our bodies, minds and the universe itself.
Using virtual reality, Ecstatic Computation is a ritual that explores the merging of consciousness and quantum energy in the physio-chemical registration of state within the computer’s memory. The moment when human and computer become one; the moment when thought becomes bit and electrons become ideas.
Sound crazy? Maybe — but check out the video demonstrations after the break. To create this experience he’s using an Oculus Rift, a Microsoft Kinect, a fan, a small keyboard and of course a computer to render it all. During the participant’s journey, [Michael] leads them in flight, passing through a quantum tunnel, merging with quantum energy inside of state registration within the computer’s memory and finally ending by falling into infinity.
All the graphics and effects are generated on the fly using GLSL generation using a robust graphics rendered called Smolder which he wrote himself, which is built on top of Cinder.

There’s a lot you can do with eye and gaze tracking, when it comes to interface design, so when [Diako] got his hands on an Oculus Rift, there was really only one thing to do.
Like a few other solutions for eye tracking we’ve seen, [Diako] is using a small camera with the IR filter removed to read the shape and location of an eye’s pupil to determine where the user is looking. This did require cutting a small hole near one of the Oculus’ eye cups, but the internal camera works great.
To get a window to the world, if it were, [Diako] slapped another camera onto the front of the Oculus. These two cameras are fed into the same computer, the gaze tracking is overlaid with the image from the front of the headset, and right away the user has a visual indication of where they’re looking.
Yes, using a computer to know where you’re looking may seem like a rather useless build, but stuff like this is used in research and extraordinarily high tech heads up displays. Although he’s not using the motion tracking on the Oculus, if [Diako] were to do so, he’d have the makings of one of the most powerful heads up displays possible.
