Over the years we’ve had the dubious honor of bidding farewell to numerous companies that held a special place in the hearts of hackers and makers. We’ve borne witness to the demise of Radio Shack, TechShop, and PrintrBot, and even shed a tear or two when Toys “R” Us shut …read more
For the last few years, the Last Great Hope™ of the consumer electronics industry has been voice assistants. Alexas and Echos and Google Homes and Facebook Portals are all the rage. Over one hundred million Alexa devices have been sold, an impressive feat given that there are only about 120 Million households in the United States, and a similar number in Europe. Look to your left, look to your right, one of you lives in a house with an Internet connected voice assistant.
2018 saw a huge explosion of Internet connected voice assistants, in sometimes bizarre form factors. There’s a …read more
Metal is many things. A material hard and coarse in nature that by forging it in fire becomes sharp enough to cut through anything in its path. The music that bares its namesake is equally cutting and exudes an unyielding attitude that seeks to separate the posers from the true acolytes. Metal is the sentiment of not blindly following the rules, a path less taken to the darker side of the street. In videogame form, there is nothing more metal than Doom.
The creators of Doom, id Software, were always hellbent on changing the perception of PC gaming in the …read more
It is good advice to change batteries in your fire alarms at least once a year. Even our low-power LCD calculators need new batteries from time to time. But at the University of Oxford, they have an electric bell that has been ringing essentially non-stop on one set of batteries for about 178 years! Is the energy crisis solved then? Perhaps not. The bells require a high voltage but very little current and the pair of batteries — piles in the parlance of 1840 — have kept the charge flowing for about 10 billion rings. As you can see in …read more
Last week, tens of thousands of people headed home from Vegas, fresh out of this year’s DEF CON. This was a great year for DEF CON, especially when it comes to hardware. This was the year independent badges took over, thanks to a small community of people dedicated to creating small-run hardware, puzzles, and PCB art for thousands of conference-goers. This is badgelife, a demoscene of hardware, and this is just the beginning. It’s only going to get bigger from here on out.
We were lucky enough to sit down with a few of the creators behind the badges of …read more
Queercon is a conference within a conference. Taking place within DEF CON, Queercon is a social network of LGBT hackers that gathers each year to host events, talks, and a kickin’ pool party. Since 2012 they have also been building electronic badges as part of the fun and I can vouch that they’re contenders for most creative badge design every single year.
A total of 450 electronic badges were made this year, and the aesthetic is as close to a polished consumer product as I have ever seen in a badge, yet they also retain the charm and feel of …read more
To the delight of everyone, this year’s official DEF CON badge is an electronic badge chock full of entertainment. Of course there is blinky, the board is artistic, and everyone hopefully maybe gets one (it’s rumored 27,000+ were manufactured) if they don’t run out. But the badge contest at DEF CON is legendary — solve all the puzzles you are awarded the coveted black badge.
The creators of this badge are no strangers to the Hackaday community. Displayed proudly on the board and in the firmware, we discover that The Toymakers are the ones who have put it all on …read more
Camera sliders are a popular build, and properly executed they can make for impressive shots for both time-lapse sequences or real-time action. But they seem best suited for long shots, as dollying a camera in a straight line just moves subjects close to the camera through the frame.
This slider with both pan and tilt axes can make moving close-ups a lot easier. With his extremely detailed build log, [Dejan Nedalkovski] shows how he went about building his with only the simplest of materials and tools. The linear rail is simply a couple of pieces of copper pipe supported by …read more
In one bad week in March, two people were indirectly killed by automated driving systems. A Tesla vehicle drove into a barrier, killing its driver, and an Uber vehicle hit and killed a pedestrian crossing the street. The National Transportation Safety Board’s preliminary reports on both accidents came out recently, and these bring us as close as we’re going to get to a definitive view of what actually happened. What can we learn from these two crashes?
There is one outstanding factor that makes these two crashes look different on the surface: Tesla’s algorithm misidentified a lane split and actively …read more
This week, Arduino announced a lot of new hardware including an exceptionally interesting FPGA development board aimed at anyone wanting to dip their toes into the seas of VHDL and developing with programmable logic. We think it’s the most interesting bit of hardware Arduino has released since their original dev board, and everyone is wondering what the hardware actually is, and what it can do.
This weekend at Maker Faire Bay Area, Arduino was out giving demos for all their wares, and yes, the Arduino MKR Vidor 4000 was on hand, being shown off in a working demo. We have …read more
