Hackaday Prize Entry: Head-up For High Voltage

[Alain Mauer] wanted to build something like a Google Glass setup using a small OLED screen. A 0.96 inch display was too large, but a 0.66 inch one worked well. Combining an Arduino, a Bluetooth module, and battery, and some optics, he built glasses that will show the readout from a multimeter.

You’d think it was simple to pull this off, but it isn’t for a few reasons as [Alain] discovered. The device cost about 70 Euro and you can see a video of the result, below.

The Simplest Smart Glasses Concept

Google Glass kind of came and went, leaving one significant addition to the English language. Even Google itself used the term “glasshole” for people who used the product in a creepy way. We can’t decide if wearing an obviously homemade set of glasses like the ones made by [Jordan Fung] are more creepy, give you more hacker cred, or just make you look like a Borg. Maybe some combination of all of those. While the cost and complexity of developing for Google Glass was certainly a barrier for hacking on that hardware, this project is just begging for you to build your own and run with the concept.

[Jordan’s] build, called Pedosa Glass, really is pretty respectable for a self-built set up. The Arduino Nano is a bit bulky, and the three push buttons take up some room, but it doesn’t kill the ability to mount them in a glasses form-factor. An FLCoS display lets you see the output of the software which [Jordan] is still developing. Right now features include a timer and a flashlight that uses the head-mounted white LED. Not much, we admit, but enough to prove out the hardware and the whole point would be to add software you wanted.

Admittedly, it isn’t exactly like Google Glass. Although both use FLCoS displays, Pedosa Glass uses a display meant for a camera viewfinder, so you don’t really see through it. Still, there might be some practical use for a little display mounted in your field of vision. The system will improve with a better CPU that is easier to connect to the network with sensors like an accelerometer — there’s plenty of room to iterate on this project. Then again, you do have an entire second ear piece to work with if you wanted to expand the system.

Check out the video demo after the break.

A Better Google Glass For $60 (This One Folds)

glassFor [Tony]’s entry for The Hackaday Prize, he’s doing something we’ve all seen before – a head mounted display, connected to a Bluetooth module, displaying information from a smartphone. What we haven’t seen before is a cheap version of this tech, and a version of Google Glass that folds – you know, like every other pair of glasses on the planet – edges this project over from ‘interesting’ to ‘nearly practical’.

For the display, [Tony] is using a 0.96″ OLED connected to an Arduino Nano. This screen is directed into the wearer’s eye with a series of optics that, along with every other part of the frame, was 3D printed on a Solidoodle 2. The frame itself not only folds along the temples, but also along the bridge, making this HMD surprisingly compact when folded up.

Everything displayed on this head mounted display is controlled by  either an Android phone or a Bluetooth connection to a desktop. Using relatively simple display means [Tony] is limited to text and extremely simple graphics, but this is more than enough for some very interesting applications; reading SMS messages and checking email is easy, and doesn’t overpower the ‘duino.

The Future Of Distraction, Right In Front Of Your Face


Say you’re meeting someone new, and instead of communicating like a normal person that wasn’t born in a barn, they play with their phone the entire time. How about a cashier or sales person who is so insufferably distracted with the Facebooks you’d guess they had a side job in the QA department of some developer? All these things will soon be a distant, horrible memory, because now you can play Flappy Bird on Google Glass.

[Rich] has had his Glass for a while now, and has been meaning to write an app for it. It took a little bit of inspiration, but when the idea of using the eye sensor to control everyone’s favorite 8-bit bird, everything fell into place. It ended up being an interesting use for the Glass, and something we actually wouldn’t mind trying out.

The bird is controlled by a double blink. In the video below, you can see there might be a little bit of latency depending on how [Rich] put the video together. Better grab that .APK while there’s still time. [Rich] says it’s a free download for anyone who’s already overpaid for a Google Glass.

Fight the Google Glass Cyborgs with Glasshole.sh

Glasshole script

We live in a connected world where social media is ubiquitous and many people feel compelled to share every waking moment with anyone who will listen. In this type of world, wearable computers like Google Glass allow us to share experiences like never before. A Glass user can take photos, record video and audio, or potentially even stream video live on the Internet with the greatest of ease. That might be great for the Glass user, but what about the rest of us? As wearable computing becomes more and more mainstream, people are naturally going to become divided on the issue of privacy. Is it a good thing to have “cyborgs” with wearable computers and cameras constantly at the ready, or is it a privacy nightmare? The cyborg war is coming, and [Julian] has already chosen his side.

It would seem that [Julian] lands on the side of the privacy advocates, based on his “glasshole” script. Glasshole is a relatively simple bash script that relies on some other common network security tools to take care of the heavy lifting. The basic premise relies on the fact that every manufacturer of network interface devices is assigned their own MAC prefix. This is a piece of the MAC address that is unique to that manufacturer.

[Julian’s] script uses a utility called arp-scan to obtain a list of all MAC addresses on a given wireless network. It then loops through each address and compares it to the known Google Glass MAC prefix. If it finds a match, it will make an audible beeping noise to alert the script user. The script then launches aireplay-ng in de-authentication mode. This will send spoofed disassociate packets to the client (in this case the Google Glass device), hopefully forcing them to disconnect from the access point. The script runs continuously, ensuring that once the device reconnects to the network it will get booted off once again. The script is designed to be run on a small Linux computer such as a Raspberry Pi or a BeagleBone black. This way, the user can carry it around with them as a sort of portable defense mechanism.

How do you fit into the cyborg war? Will you stand proudly with your computer on your face for all to see? If so, what kind of countermeasures would you deploy to prevent this type of attack from working on you? If not, what other types of interesting attacks can you think of to keep the cyborgs at bay?

The Raspberry Eye Sees All

[Roman Rolinsky] wanted to try to do something interesting with his Raspberry Pi and a 2.4″ LCD he had laying about… So he made a rather bulky version of Google Glass.

We’ve seen a few examples of home brew Google Glass before, or even real-life subtitle glasses used for translation on the fly, but what we really like about [Roman’s] project (besides the fact he hosted it on our very own awesome project hosting site) is that he’s put together the projection system himself out of basic components.

To create the HUD, he’s using a semi-transparent mirror which he took out of a game of Khet 2.0 called the Eye of Horus Beamsplitter — which is a really cool real-life puzzle board game like those games where you have to reflect the laser to solve a puzzle. He’s then using a 3x Fresnel magnification lens which is placed over top of his 2.4″ LCD in a 3D printed enclosure. This magnifies and reflects the image onto the mirror which is placed directly over his eye, allowing for a see through display.

Stick around after the break to see a video of the Raspberry Eye in action!

Hackaday Links: March 3, 2014


If you’re playing along with Twitch Plays Pokemon, you might as well do it the right way: with the smallest Game Boy ever, the Game Boy Micro. [Anton] needed a battery replacement for this awesome, discontinued, and still inexplicably expensive console and found one in a rechargeable 9V Lithium battery. You get two replacement cells out of each 9V battery, and a bit more capacity as well.

Every garden needs garden lights, right? What does every garden light need? A robot, of course. These quadruped “Toro-bots” react to passersby by brightening the light or moving out of the way. It’s supposed to be for a garden that takes care of itself, but we’re struggling to figure out how lights will do that.

Flexiable 3D prints are all the rage and now resin 3D printers are joining the fray. The folks at Maker Juice have introduced SubFlex, a flexible UV-curing resin. The usual resins, while very strong, are rock solid. The new SubFlex flexible resins are very bendable in thin sections and in thicker pieces something like hard rubber. We’re thinking custom tank treads.

Remember this post where car thieves were using a mysterious black box to unlock cars? Looks like those black boxes have moved from LA to Chicago, and there’s still no idea how they work.

Have a Google Glass? Can you get us on the list? [Noé] and [Pedro] made a 3D printed Google Glass adapter for those of us with four eyes.
