What would happen if Oculus-quality virtual reality was created in the 80s on the Commodore PET? [Michael Hill] knows, because he created a stereoscopic video headset using a PET.
This build is an extension of [Michael]’s exhibit last year at VCF East where he displayed a video feed with PETSCII. Yes, that means displaying video with characters, not pixels.
This year, he’s doubling the number of screens, and sending everything to two iPhones in a Google Cardboard-like VR headset. Apart from the optics, the setup is pretty simple: cameras get image data, it’s sent over to a PET, and a stream of characters are sent back.
It’s impossible to film, and using it is interesting, to say the least. Video below.

Virtual reality has come a long way but some senses are still neglected. Until Smell-O-Vision happens, the next step might be feeling the wind in your hair. Perhaps dad racing a sportbike or kids giggling on a rollercoaster. Not as hard to build as you might think, you probably have the parts already.
Off-the-shelf devices serve up the seeing and hearing part of your imaginary environment, but they stop there. [Jared] wanted to take the immersion farther by being able to feel the speed, which meant building his own high power wind generator and tying it into the VR system. The failed crowdfunding effort of the “Petal” meant that something new would have to be constructed. Obviously, to move air without actually going on a rollercoaster requires a motor controller and some fans. Powerful fans.
A proponent of going big or going home, [Jared] picked up a pair of fans and modified them so heavily that they will launch themselves off of the table if not anchored down. Who overdrives fans so hard they need custom heatsinks for the motors? He does. He admits he went overboard and sensibly way overbudget for most people but he built it for himself and does not care.

Many of us have gone on a stationary romp through some virtual or augmented scape with one of the few headsets out in the wild today. While the experience of viewing a convincing figment of reality is an exciting sensation in itself, [Mark Lee] and [Kevin Wang] are figuring out how to tie other senses into the mix.
The duo from Cornell University have built a mechanical exoskeleton that responds to light with haptic feedback. This means the wearer can touch the sphere of light around a source as if it were a solid object. Photo resistors are mounted like antenna to the tip of each finger, which they filed down around the edges to receive a more diffused amount of light. When the wearer of the apparatus moves their hand towards a light source, the sensors trigger servo motors mounted on the back of the hand to actuate and retract a series of 3D printed tendons which arch upward and connect to the individual fingers of the wearer. This way as the resistors receive varying amounts of light, they can react independently to simulate physical contours.
One of the goals of the project was to produce a working proof of concept with no more than 100 dollars worth of materials, which [Mark] and [Kevin] achieve with some cash to spare. Their list of parts can be found on their blog along with some more details on the project.

At the Atmel booth at Maker Faire, they were showing off a few very cool bits and baubles. We’ve got a post on the WiFi shield in the works, but the most impressive person at the booth was [Quin]. He has a company, he’s already shipping products, and he has a few projects already in the works. What were you doing at 13?
[Quin]’s Qduino Mini is your basic Arduino compatible board with a LiPo charging circuit. There’s also a ‘fuel gauge’ of sorts for the battery. The project will be hitting Kickstarter sometime next month, and we’ll probably put that up in a links post.
Oh, [Quin] was also rocking some awesome kicks at the Faire. Atmel, I’m trying to give you money for these shoes, but you’re not taking it.
[Sophie] had a really cool installation at the faire, and notably something that was first featured on hackaday.io. Basically, it’s a virtually reality Segway, built with an Oculus, Leap Motion, a Wobbleboard, an Android that allows you to cruise on everyone’s favorite barely-cool balancing scooter through a virtual landscape.
This project was a collaboration between [Sophie], [Takafumi Ide], [Adelle Lin], and [Martha Hipley]. The virtual landscape was built in Unity, displayed on the Oculus, controlled with an accelerometer on a phone, and has input with a Leap Motion. There are destructible and interactable things in the environment that can be pushed around with the Leap Motion, and with the helmet-mounted fans, you can feel the wind in your hair as you cruise over the landscape on your hovering Segway-like vehicle. This is really one of the best VR projects we’ve ever seen.
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.
Aiming to be the leader in Virtual Reality horror experiences is the immersive VR haunted house in Seattle called ‘The Nightmare Machine’ which promises to be one of the most terrifying events this Halloween. But they need some assistance raising money to achieve the type of scale on a large public level that the project is attempting. The goal is $70,000 within a 30 day period which is quite the challenge, and the team will need to hustle every single day in order to accomplish it.
Yet the focus of the project looks good though, which is to lower the massive barriers of entry in VR that are associated with high hardware costs and provide people with a terrifying 5 minutes of nightmare-inducing experiences. This type of fidelity and range is usually only seen in military research facilities and university labs, like the MxR Lab at USC. And, their custom-built head mounted displays bring out this technology into the reach of the public ready to scare the pants off of anyone willing to put on the VR goggles.
The headsets are completely wireless, multi-player and contain immersive binaural audio inside. A motion sensing system has also been integrated that can track movements of the users within hundreds of square feet. Their platform is a combination of custom in-house and 3rd party hardware along with a slick software framework. The technology looks amazing, and the prizes given out through the Kickstarter are cool too! For example, anyone who puts in $175 or more gets to have their head 3D scanned and inserted into the Nightmare Machine. The rest of the prices include tickets to the October showcase where demos of the VR experience will be shown.

One of our trusty tipsters named [Arman] wrote in to tell us about this awesome little Horror VR Hackathon that sought to create a non-lethal electric chair, for a seriously creepy and shocking experience.
[Arman] works in a small prototyping shop, so when a few guys from the local VR group called to ask for help building a non-lethal electric chair, he thought they were joking — until they showed up at the shop! Finally understanding what they really wanted to do, he hooked them up with an EL wire power supply (high voltage AC, low amperage) for their first prototype.
Unfortunately the EL power supply driver took too much juice, so they called [Arman] back the next day to hack together some of those joke gum shockers instead — he hooked them up to an Arduino and they work like a charm.
