A Hacked WiFi Router, an API, and a Toy Bus: It's the Ambient Bus Arrival Monito 53

JohnGrahamCumming writes "In this simple project, a hacked Linksys WRT54GL talks to a public API to get real-time bus information, and displays the times of the next buses on a model bus. Never miss the bus again! 'It's possible to reflash the Linksys with a custom Linux installation that lets me control the box completely (and still use it as a wireless router). There are various project, but I used OpenWRT. With OpenWRT it's possible to SSH into the box and treat it as any Linux server (albeit a rather slow one). But there's plenty of power to grab bus times and update an LED display connected to the WRT54GL's serial port. "

DIY Augmented Reality Heads-Up Display 39

mkwan writes "A PhD student in Melbourne, Australia, has built an augmented reality head-up display using a baseball cap, an Android smartphone, and off-the-shelf optics. It won't win any awards for style or practicality, but it's a fun way to use Wikitude. All we need now is a Terminator-vision smartphone app." Not nearly as modern, but vaguely related: the Private Eye P4.

iFixit's Kyle Wiens On the War On DIY Electronics 760

pigrabbitbear writes with an excerpt from an article at Motherboard: "Anyone planning on buying a new iPad should know what they're getting themselves into by now. In recent years, Apple and other hardware manufacturers have made it liquid-crystal clear that they're not fond of the idea that customers can tear open and fix products without the help of licensed repair specialists. Even if it's as easy as ordering a part online and following a few instructions gleaned from a Google search, hardware companies generally seem to prefer we keep the hood closed. It should not be surprising, then, that the latest version of Apple's much-desired tablet has one 'killer' feature that's finally getting the attention it deserves: A design that stops you from getting inside of it."

Reinventing the Clapper With a Knock-Based Home Automation Controller 92

An anonymous reader writes with a snippet from Hack a Day: "Clap On! Clap Off! was super awesome when The Clapper came out in the mid-eighties. Now [Mathieu Stephan] is trying to make the concept much more functional. He put together a controller that lets you knock on walls to control things around the house. It's called the Toktoktok project and uses small boxes to receive user input and control items like lamps and computers." As the project website points out, Stephan is keeping the project intentionally open.

Is It Time For Hacker Scouts? 186

ptorrone writes "MAKE Magazine asks: is it 'Time For Girl Scouts and Boy Scouts 2.0?' What might the future of education be like if it were based on online & earned skill badges, and what could the future of traditional organizations for kids, like the Boy Scouts and Girl Scouts, be like in a very modern, tech-savvy world? Social networks and the maker movement are the perfect intersection of where the kids of today are, but we don't see 'leaderboards' for skills yet; we only see them for video games. Is it time for Hacker Scouts?"

Remote-Controlled Planes Used For Wildlife Conservation Screenshot-sm 48

Damien1972 writes "Conservationists have converted a remote-controlled plane into a potent tool for conservation. The drone — an HK Bixler equipped with cameras, sensors and GPS — has been used to map deforestation, count orangutans and elephants, and get a bird's eye view of hard-to-access forest areas. During their 4 days of testing in Sumatra, the drone flew 30 missions without a single crash. A mission, which typically lasts about 25 minutes, can cover 50 hectares. The drone, full equipped, costs less than $2,000."

Video Slashdot Visits Metrix Create:Space in Seattle (Video) Screenshot-sm 27

Metrix Create:Space is full of people busily making electronic gadgets. And shot glasses. And everything in between. Some of them saw the street-level sign and stopped in out of curiosity, while others are long-time createspace scenesters. It doesn't matter which you are, says Metrix founder Matt Westervelt. Come in and make something. Need new skills? They have workshops. And lots of great tools.

Tetris In 140 Bytes 215

mikejuk writes "Is it possible to write a JavaScript program in no more than a tweet's length? A website called 140byt.es says it is and has an implementation of Tetris to prove it. Ok, it only has two types of block — hence its title "Binary Tetris" — and there's no rotate, but it works. The blocks fall down the screen and you steer them into place. You can try it out by playing the demo. Of course the real fun is in figuring out how it works and there is lots of help on the site — so if you're bored how about the 140 character challenge?"

Stanford's Francis Fukuyama Builds Personal Surveillance Drone 92

HerbieTMac writes "Political science professor Francis Fukuyama builds and flies his own personal surveillance drones. His current model requires ground visibility but he is working on the HAM license that would allow fully remote operation. His YouTube videos (video 1 , video 2) are particularly impressive." I had no idea that Francis Fukuyama had such technical interests.

TMS9918A Retro Video Chip Reimplemented In FPGA, With VGA Out 126

acadiel writes "Matthew H from the AtariAge.com TI-99/4A forum has finalized a design of a TMS 9918A replacement (with VGA out) for classic computer systems such as the ColecoVision, TI-99/4A, SpectraVision, MSX1, SpectraVision 128, and Tomy Tutor Home computers. This hardware project replaces the native video controller on these classic systems and enables them to have VGA output for the first time." (It's just under $100 to order one.)

83-Year-Old Woman Gets New 3D-Printed Titanium Jaw 121

arnodf writes "The University of Hasselt (in Belgium) announced today (Google translation of Dutch original) that Belgian and Dutch scientists have successfully replaced an 83-year-old woman's lower jaw with a 3D-printed model. According to the researchers, 'It is the first custom-made implant in the world to replace an entire lower jaw. ... The 3D printer prints titanium powder layer by layer, while a computer controlled laser ensures that the correct particles are fused together. Using 3D printing technology, less materials are needed and the production time is much shorter than traditional manufacturing. The artificial jaw is slightly heavier than a natural jaw, but the patient can easily get used to it."

Ask Slashdot: Techie Wedding Invitation Ideas? 399

Qa32 writes "I am getting married in a few months and being a hardcore techie I wanted to come up with some novel way of making my wedding invite that will truly have even my mom say, 'wow, that was cool.' Has anyone out there done anything similar, or have you thought of something similar you'd like to share? I already have a few: have QR codes, have some basic embedded circuit/plate with wire leads that maybe plays a song when you connect a battery, have a way to turn up a display LCD, etc."

Android Kinect Projector Interface 45

An anonymous reader writes "A guy who goes by the online handle DDRBoxman decided it would be fun to blow up his Samsung Galaxy Nexus display onto the wall by connecting his phone to a projector. He then connected the whole thing to a PC and, thanks to Microsoft's open-source Kinect platform for Windows, he was able to create a custom ROM that mapped out the phone interface to the Kinect sensors. Pretty neat!"

Pirate Bay To Offer Physical Item Downloads 343

lukehopewell1 writes "The Pirate Bay is offering users the chance to download and print out real objects using 3D printers in what the pirate site is hailing as 'the future.'" Amir Taaki mentions that among the new "physibles" uploaded to the Pirate Bay are "plans for a tabletop replica for a Warhammer 40k dreadnought that got taken down in December with a DMCA request." Downloadable 3D models have been around for a while; MakerBot users are probably all familiar with the Thingiverse. Couple TPB with a cheap method of accurate 3D scanning, though, and I wonder what illegal shapes will emerge.

Ask Slashdot: Tips On 2D To Stereo 3D Conversion? 125

An anonymous reader writes "I'm interested in converting 2D video to Stereoscopic 3D video — the Red/Cyan Anaglyph type in particular (to ensure compatibility with cardboard Anaglyph glasses). Here's my questions: Which software(s) or algorithms can currently do this, and do it well? Also, are there any 3D TVs on the market that have a high quality 2D-to-3D realtime conversion function in them? And finally, if I were to try and roll my own 2D-to-3D conversion algorithm, where should I start? Which books, websites, blogs or papers should I look at?" I'd never even thought about this as a possibility; now I see there are some tutorials available; if you've done it, though, what sort of results did you get? And any tips for those using Linux?

Alternative Android Market To House Banned Apps 114

sl4shd0rk writes "In contrast to the Apple's iron-fisted control over their App store, the Android Market is much more open. Google does, on occasion, remove apps it deems inappropriate, such as emulators, legally-questionable music services, tethering apps and one-click root apps. But if Koushik Dutta of CyanogenMod fame has his way, these heretic apps may have a home after all. Dutta plans an 'underground' Android Market complete with an approval process to weed out malicious applications; something Google doesn't do. Ideally, this will give Android users a more trustable source from which to get applications without having to resort to dictatorial software control."

Silver Solution Ink Makes Faster Flexible Circuits 36

judgecorp writes "Silver-based compounds dissolved in ammonia could make finer and more flexible circuits, according to researchers at the University of Illinois. Existing inkjet based circuit printing systems use particles which are less predictable. The silver-based ink remains dissolved until the ammonia evaporates, and can be delivered through 100nm nozzles. In all senses, it's a better solution."
