Engadget has decided to give this whole crowd-funding thing a try with a competition called Insert Coin. This is part of an upcoming event called Expand that is supposed to let us get inside information on gadget construction and conception. This actually sounds refreshing compared to the giant commercial that other tech conferences can be [...]

This quick and easy evaporative cooler might be just the thing the next time the air conditioning goes on the fritz. [Stephen] saw an eBay listing for a personal air conditioner that used a moist sponge and fan to send some cool relief your way. But he wanted to run his own test to see [...]

We suppose the only thing more useless than a most useless machine is giving it an emoticon face. But that’s exactly what has happened with this project. But you’ll want to seen the whole thing, as the presentation involves much more than an angry box that can shut itself off. This is the second iteration [...]

It’s a blur, but you really don’t want to seen this thing coming for you anyway. It’s the latest look at what the folks at Boston Dynamics have been working on under a DARPA contract. They call it the Cheetah robot as it’s the fastest four-legged bot ever developed. The clip after the break shows [...]

[LokisMischief] wrote in to the tip line to let us know about this incredible home made CO2 laser. This thing is a complete DIY beauty, from the PVC cooling jacket to the toolbox based controller. The whole thing is essentially built from DIY parts, hand blown glass for the laser tube, plumbing store mirror mounts, [...]

Chaos Communication Camp 2011 Abstract: Everything we do as technologists depends on the critical minerals from which our devices are made. Recycling junk electronics is no longer just the right thing to do, it's the smart thing to do. Everything we do as technologists depends on the critical minerals from which our devices are made. From iron, aluminum and plastic, to gold, coltan and rare earth metals impact, these raw materials affect the availability and price of the electronics we use all the time. What happens at the end of their useful lives? By now, the problems with electronic waste are well known: Recycling is difficult and expensive, and exportation of junk electronics from rich to poor nations incentivizes informal recycling that is incredibly dangerous to workers and harmful to the environment. But with extreme monopolization of certain mineral markets, particularly China's domination of the rare earths market, recycling has ceased to be simply a good thing to do, and now provides an economic hedge against volatile commodities markets. This talk will be an update of a talk I gave at The Next Hope (July, 2010, New York City, link below) and will outline the e-waste problem and how both regulations and materials innovation in places like the EU and Japan have put them ahead of the manufacturing curve, with special emphasis on rare earth elements. Any specific questions from economics to chemistry that are sent in advance, will be researched and answered the best I can. I work at a research university so there are lots of smart people to ask. A draft of my capstone paper is available if you'd like to take a closer look at how I approach the topic. Please note that the paper linked below is a draft...the final draft is due May 3, after the deadline for talk submissions! Talk image is courtesy of Greenpeace.

There are few things more frustrating than being in the middle of working on a project and realizing that you are missing some crucial component that ties the whole thing together. According to Murphy’s Law, this sort of thing will only happen when parts are completely impossible to procure. If you’re ever hunting for a [...]

The fan motor on [Pete's] oscillating tower fan conked out on him. It’s a shame to throw away the whole thing, but it’s near impossible to source parts for a small appliance like this one. So he set out to rebuilt the motor and get the thing working like new. The motor in question is [...]

So yeah, this thing exists. Well, at least some pretty interesting looking prototypes of it do. It’s the C-1 from Lit Motors (anyone else think that’s a reference which belongs in /r/trees?). The idea here is that the small form-factor of a motorcycle is very efficient and easily maneuverable. But the cage protecting the passenger from [...]

[Matthew Riese] got frustrated waiting for the future to arrive so he could have his flying car. He decided to take things into his own hands and construct the closest thing he could. This turned out to be a hovercraft. Not only that, but he thought that the most fitting shape for this thing would [...]

Hearing that Chumby will no longer be selling hardware makes us a little sad. We’ve seen this thing used for so many different things, like shooting people with missiles, spitting out composite video, web serving, stomping around bipedially, and being a 3g router. We knew it wouldn’t be long, since they actually stopped manufacturing last [...]

In our digital age prying eyes are everywhere. The sad thing is that they may even belong to your own government. But no matter who it is, there are some things you can do to keep your private digital devices and content as secure as possible. The link above goes to [Jerry Whiting's] discussion on [...]

If you’re looking for a piece of custom furniture to anchor your child’s playroom, this Rubik’s cube chest of drawers is just the thing. [Makendo] went the extra couple of miles on the project, building the entire thing from scratch and adding one clever feature after another to make it something special. It’s made up [...]

Black Hat USA 2010 Abstract: 0-days are a lot of fun. Whether it’s an overlooked buffer overflow, a poorly implemented encryption algorithm, or something downright bizarre, the thrill of breaking things is the reason most of us get hooked. That’s why Trustwave’s Global Security report is a bit sobering. Why are so many of these systems still vulnerable to SQL injection, LANMAN hash recovery, and default password guessing? And is an NFS exploit considered a 7665-day? But this isn’t about getting bent out of shape about the state of information security. Without being too preachy, this talk is about what we can do to help turn things around. Because if there’s one thing that is clear, the need for information security will only increase. And we’re all feeling the growing pains. The end of 2009 brought with it a great deal of controversy over the effectiveness of information security. We’re all pretty frustrated about it. But that’s the thing about growing up – you start to realize your own limitations. Like dieticians and dentists, we watch people make bad choices and wonder where we went wrong. And like them, we need to focus on the fundamentals: eating healthy, brushing your teeth, and blocking port 139. But man, that sounds pretty boring. So maybe it’s time for a new approach. Maybe it’s not so much about the message, but how it’s getting delivered. And maybe there’s something we can do about that. After all, we’re pretty secure folks – we can handle the touchy-feely stuff, right?

[Grenadier] has a thing for the high voltage and, as you can see, he’s found multiple ways to build the icon of HV toys - a Jacob’s Ladder. The three look similar, but they use different means of generation the voltages necessary to get a spark to jump through the air. The exhibit on the left uses [...]

One thing that always amazes us is the ingenuity displayed by prison inmates, as demonstrated in the tools and weapons they create while under the watchful eye of the law. Unlike most people however, these individuals have nothing but time on their side, which lends to the wide range of implements they inevitably dream up. [...]

Looking for more ways to enhance his 3D printer, [JJ] decided to make it wireless. He got his hands on some $10 Bluetooth modules and figured this would be just the thing to make the link with his laptop. They came as surface mount modules, so the first thing he had to do was develop [...]

From time to time we consider the ramifications of hacking prowess being used for evil purposes. Knowledge is a powerful thing, but alone it is not a dangerous thing. Malicious intent is what takes a clever project and turns it to a tragic end. Conscientious hackers realize this, and [George Hadley] is one of them. While working [...]

It seems that there has been some shenanigans happening with the OSHW logo voting page as some are using scripts to game the system for their favorite design. Why? Who knows… How? Well one of the advocates of OSHW [Bill Porter] set about figuring that out, and things should be patched up now, though that [...]

[Pete] was hard at work putting off a repair job for a friend, and wondered how much longer he could possibly procrastinate. With no fellow humans in earshot to which he could propose this question, he thought it would be great if he could ask a Magic 8-ball for an answer. Alas, he doesn’t have [...]

Given a box full of cockroaches, the first thing most of us would do is try to locate the nearest source of fire. Lucky for the roaches, the team over at Backyard Brains look at things a bit differently than we do. Their latest effort combines cockroaches and electronics to create a bio-electrical hybrid known [...]

Augmented reality is a pretty neat thing but we don’t want to live our lives staring at a smartphone as we walk around. [F00] didn’t either so he built these augmented reality glasses. You can see a hole in the middle of the glasses where he added a webcam. The camera captures the image in [...]
