The venerable Commodore 64 got a lot of people started in computers, and a hard core of aficionados keeps the platform very much alive to this day. But a C64 just doesn’t have the horsepower to do anything more than some retro 8-bit graphics games, right?
Not if [jim_64] has anything to say about it. He’s created a pair of virtual-reality goggles for the C64, and the results are pretty neat. Calling them VR is a bit of a stretch, since that would imply the headset is capable of sensing the wearer’s movements, which it’s not. With just a small LCD screen tucked into the slot normally occupied by a smartphone in the cheap VR goggles [jim64] used as a foundation for his build, this is really more of a 3D wearable display — so far. The display brings 3D-graphics to the C64, at least for the “Street Defender” game that [jim64] authored, a demo of which can be seen below. We’ll bet position sensing could be built into the goggles to control the game too. Even then it won’t be quite the immersive (and oft-times nauseating) experience that VR has become, but for a 35-year old platform, it’s not too shabby.
Looking for more C64 love? We’ve got a million of ’em — case mods, C64 laptops, tablets, even CPU upgrades.

If you’ve always wanted to see in the dark but haven’t been able to score those perfect Soviet-era military surplus night vision goggles, you may be in luck. Now there’s an open-source night vision monocular that you can build to keep tabs on the nighttime goings-on in your yard.
Where this project stands out is not so much the electronics — it’s really just a simple CCD camera module with the IR pass filter removed, an LCD screen to display the image, and a big fat IR LED to throw some light around. [MattGyver92] seemed to put most of his effort into designing a great case for the monocular, at the price of 25 hours of 3D printer time. The main body of the case is nicely contoured, the eyepiece has a comfortable eyecup printed in NinjaFlex, and the camera is mounted on a ball-and-socket gimbal to allow fine off-axis angle adjustments. That comes in handy to eliminate parallax errors while using the monocular for nighttime walks with both eyes open. One quibble: the faux mil-surp look is achieved with a green filter over the TFT LCD panel. We wonder if somehow eliminating the red and blue channels from the camera might not have been slightly more elegant.
Overall, though, we like the way this project came out, and we also like the way [MattGyver92] bucked the Fusion 360 trend and used SketchUp to design the case. But if walking around at night with a monocular at your face isn’t appealing, you can always try biohacking yourself to achieve night vision.
We can’t see much without our glasses (which is why our habit of shaving in the shower often ends badly). Our glasses cost a bundle, but we wear them every waking moment so it’s worth it. But only recently did we break down and spring for prescription sunglasses. However, when it comes to sports we don’t pony up the dough for dedicated specs. Here’s a hack that will change that. If you’ve still got your last set of glasses on hand hack up the lenses for swimming goggles or other applications.
In this case [Dashlb’s] lenses were already small enough to fit in the goggles. He simply added a bead of Sugru around the edges to hold the lenses in place. But if you do need to cut them to size aligning the lenses with your eyes is important, so we suggest the following: have a buddy stand in front of you and mark the center of your pupil on the glasses, as well as the goggles. If you need to cut down the lenses (which are probably a type of polycarbonate) just make sure the marks match up before doing any cutting.
We might give this a try with some wrap-around sunglasses to make an inexpensive pair of prescription cycling shades.
[Chris] has been hard at work building a Heads Up Display into some Snowboarding goggles. We’re used to seeing the components that went into the project, but the application is unexpected. His own warning that the display is too close to your face and could cause injury if you were to fall highlights the impractical nature of the build. But hey, you’ve got to start somewhere when it comes to prototyping. Perhaps the next iteration will be something safe to use.
A set of MyVu glasses were added to the top portion of the goggles, which lets the wearer view the LCD output by looking slightly up. The display is fed by a Raspberry Pi board which connects to a GPS module, all of which is powered by a USB backup battery. In the video after the break you can see that the display shows time of day, speed, altitude, and temperature (although he hasn’t got a temperature sensor hooked up just yet). His bill of materials puts the project cost at about £160 which is just less that $250.

Lots of people build custom steampunk goggles, but most don’t implement any interactivity – they’re just an aesthetic accessory. [Sarah] recently decided to built a pair that, besides looking cool, would engage the wearer in creating sound. She accomplished this by integrating an optical theremin into their design.
To keep the build both affordable and wearable she researched simplified theremins, and eventually settled on creating a basic model that uses only a handful of components and two 555 timers. The main body of the goggles was constructed using mostly random mismatched pieces of metal and leather. Mounted on the outer edge of each lens, there is a photo sensor and a corresponding slider control. Adjusting the slider alters the level of resistance, therein changing the pitch of the sound. The theremin will produce different pitches and octaves depending on how much light the sensors receive. So, the wearer, or a nearby friend, waves their hands around the wearers head to control it.
The speaker and volume knob are cleverly disguised as the two ‘lenses’. Rotating the volume knob lens adjusts an internal potentiometer that’s held in place by a custom laser etched piece of acrylic. To top it all off, she even designed her own PCB using Eagle.
Check out a video demonstration after the break.

[D S] wanted his own head-mounted display. What you see here is just his mockup, but somewhere along the way he realized it’s closer to a finished build than just being a stating point. Not only does it work well for gaming, it came in at under $200 all in. You think your girlfriend makes fun of you now for wearing that big microphone headset while playing? Just wait until she gets a load of these!
We’ve embedded an image gallery after the break as well as the description he sent us with his email. The display itself is a 7″ LCD module from eBay that boasts a hair better than 720P resolution: 1280×800. He’s using a pair of ski goggles to strap the display to his noggin. The enclosure is made out of foam board which should help keep the weight down. Inside there’s a Fresnel lens but after reading his description of how he measured the focal length we’re still not 100% clear on how he figured out where to mount it.
Though it may be missing the 3d of the rift,a quick mod could fix that and he’ll be well on his way through the journey to building his own Holodeck.
