[Voja Antonic] has built a clock that tells the time in binary with square waves, and trolls the uninitiated in electronics.
The clock itself is very attractive. If you look closely you can see the circuitry backlit behind the dot LED matrix display. The whole thing is housed in a nicely folded steel case. RGB LEDs are used to good effect to highlight some additionally obfuscating circuit schematics. The workmanship is very top notch, and we would gladly host such an object on our desks.
The clock’s standard time telling mode is three sets of square waves showing the binary values for the hours, minutes, and seconds. Every now and then the clock will glitch out. The waves will distort. The colors will change. And every now and then, tantalizingly, the alpha-numeric time will show up for just a split second, before returning to those weird squiggles again.
We’ve seen a whole slew of binary clocks before. This one, for instance. But the waveform display makes us feel just that little bit more at home — it’s just like we’re sitting in front of our oscilloscope.
It looks like a genetic leap has unleashed the age of mutants, but this is really just a few guys trolling New York City with some custom RC aircrafts. The video after the break shows the fliers up close. They’re pretty much full size, we’d guess 5’10” from head to heel. The outstretched arms and body act as wings, while the legs act as ailerons and rudders. But from afar (or even a medium distance) it’s quite difficult to make out the flat surfaces… they look like office workers loosed from their cubicles.
Unfortunately we don’t have more than a flight demo to share with you. If you know where to find build info (or any extra details at all actually) don’t forget to send in a tip. We wonder if these are the same guy who made the flying hero we posted back in July?
There’s another nugget of delight right at the beginning of the video. A sweet octocopter which looks much like this one was used to capture the aerial footage.

If you’ve been keeping up with our featured stories this year you’ll remember the post about using your own eyelids as 3D shutter glasses. Throngs of commenters called this one as fake and they were right. But we still enjoyed the experience… it’s more fun to be trolled when the trolls are skilled and idea is original. The perpetrators have released a follow-up video that shows how it was done. It’s not just an electronic trinket and some acting. There’s well executed post-production which maps out the area around this gentleman’s eyes and edits in the rhythmic blinking that made the farce somewhat believable. Check it out after the break.

Sometimes we like to take a few minutes away from Hackaday to spend time with our families. But just when you take your eyes off of the incoming comments, Trolls are bound to strike. Well, [Caleb] and I found a solution to the problem in the form of a troll sniffing rat. This beady-eyed vermin sits on my desk and waits. When a trolling comment is detected its eyes glow red and an alarm is sounded. Join us after the break for more about this silly project.

In the cold and mysterious wilderness of Norway, it pays to be ready for anything–especially heavy-walking trolls. The team at [nullohm] decided to prepare thoroughly for their trek into the woods to witness the Leonids meteor shower by putting together an Arduino-based “troll detector”.
The device is based on the superstition of hammering a steel spike into a tree to keep trolls away from camp. This goes one step further by including an accelerometer and LED indicators so that you can tell exactly what type of troll is just about to feast upon your tender human flesh.
When the detector is installed into a nearby tree, it takes an average seismic measurement and then looks for telltale footfalls. Even if you’re not concerned with perpetuating superstitions, you might find a use for the source code for simple seismic activity monitoring at home to supplement your miniature seismic reflector.
Through the years, our reader base has grown like we never could have imagined. We thank everyone for reading, and owe our gratitude to all who have sent in submissions. We live for them. The more high quality submissions you send in, the more we’ll post. Along with you, we’ve taken part in some really great projects and enjoyed the writing of some really great people.
Now it is time to share our plans for the future with you. We have two announcements that we would like to get your thoughts on.
Hack a Day first started as an offshoot of Engadget. It was a place where we were able to look at things from a hacker perspective. Contrary to what some people believe, it wasn’t all hardcore electronic engineering. It wasn’t even all projects. We had fun, and discussed our thoughts on many things that weren’t that complicated.
As we move forward, we will be covering a wide variety of posts. From simple things, like teardowns to the amazingly complex projects that inspire us all. We intend to get you original content from the perspective of people who are not just consumers, but hackers of all different skill levels.
We are working to make it easier to browse the site, with your specific interests in mind. Our first motion was to add the “Classic Hacks” category which gathers up the more complicated projects. We’re open to other ideas of how to best categorize the content to make your experience better.
#2. Social Interaction:
Since the beginning of Hack a Day, we have been inundated with questions and requests. People are asking for help on existing projects as well as trying to break into the complexities that can lay in front of a beginner. We’ve seen unofficial Hack a Day forums come and go, but we think it is time that we did something ourselves. We’ve been working behind the scenes on a really slick system which allows people to ask questions, get answers, and even rate and give feedback.You will hopefully see this appear in a matter of weeks as we finish up the last bits.
We look forward to seeing some of you shine, sharing your knowledge with the hacker community.
