The team at Eschelle Inconnue wanted to “trace a sound cartography of Islam” in Marseilles, France, so they came up with a clever little GPS walking tour powered by an Arduino, MP3 playback module, and a surface transducer speaker. The team used a Processing app to define geographic areas where...

[MyMagicPudding] wanted to try his hand at hobby electronics, so he decided to go all-in and build himself a PIP-Boy 3000. If the name doesn’t ring a bell, the PIP-Boy 3000 is a wrist-mounted computer from the popular Fallout video game series. The PIP-Boy is based around an HTC Desire HD mobile...

[Igor] helped his friend’s family out by retrofitting an old Philco television with a newer flat panel (translated). The original conked out over thirty years ago, but the look of it still held quite a bit of nostalgia for his girlfriend’s Grandmother. She showed it to him on a recent visit and...

When we see artists like Daft Punk or Madeon working their magic in a live setting, we’re always impressed with their controllers. Sample-based artist use controllers like the Monome and Kaoss Pad a lot, but these devices are fairly expensive. Thankfully, we live in an age of multitouch...

[Adam Outler] and [Rebellos] have been working feverishly to advance the world of mobile device hacking. They’re attacking on two fronts, making it easier for the common hacker to monkey with the phone’s firmware and OS with impunity, and by finding ways to make regular handsets into...

Why build a pick and place machine from the ground up when you can start with a full featured, but non-functional unit, and bring it back to life. That’s exactly what [Charliex] is doing with this Juki 360 rebuild. A bit of background is in order here. [Charliex] is working alongside other...

[vinod] sent in his replica of a Snake game, the game to play on old Nokia dumb phones. The build is based on a PIC16F877 microcontroller just like previous Snake builds we’ve seen, but [vinod] didn’t use physical buttons in his build. Instead, he used a Philips infrared TV remote to control the...

Winter’s coming, and you don’t want to be outdone by your neighbor’s new snow blower. We think it’s pretty safe to say you’ll be the envy of gearheads throughout the neighborhood if you can build your own snow blower around a V8 engine. [Kai Grundt] is a metal fabricator by day and a horror...

Hackaday reader [equinoxefr] posted some images to our flickr pool showing off some modifications he made (Google Translation) to his La Crosse WS2305 weather station. Having built other router-based weather stations in the past, [equinoxefr] was looking for a better way to gather weather data...

In March, we sent the Code Junkie to Las Vegas, to attend Visual Studio Live!, and now it’s your turn! As a thank you for continuing to help support CodeBetter.Com/Devlicio.us and our community of friends here, we’ve arranged (thanks to the generous support from Visual Studio Live!) to give away...

In a little more than a month, tens of thousands of people around the world will attend a class on Artificial Intelligence at Stanford. Registration for this class is still open for both class ‘tracks’. The “basic” track is simply watching lectures and answering quizzes, or a slightly more...

The team at czANZO, the Czech Amateur Near-Space Object group, sent up one of the best high-altitude balloons we’ve ever seen last weekend and the resulting video is remarkable. The team’s build blog (Google Translate link for everyone without Chrome) goes through the design and construction of...

As [Plasma2002] put it, “Those jumbo screens at concerts that display your text messages can be a lot of fun. Wouldn’t it be great if you could have the same thing for your own parties or social gatherings?” The answer to this question came in the form of this hack, a scrolling marquee sign that...

Why is it that we abhor large numbers of references in our .Net projects? Beyond the obvious that is (I don’t care about start up time, or any other performance hogwash). It seems that early in my career I thought 10 assembly references was absurd, now that number is MUCH higher (almost without...

[Andy] stuffed some more RAM onto an Arduino Mega and his three-part walk through on the design, construction, and software is a great read and one of the more ‘hard core’ Arduino builds we’ve seen. The build is centered around a 512K × 8 SRAM module [PDF warning]. Because the RAM is divided up...

Imagine our surprise when we learned [Bruce Simpson], who made headlines in 2003 with his $5000 DIY cruise missile, is still alive, not illegally interned in a black ops prison, and still doing what he does best: building really awesome remote-control airplanes. The first...

As many of you many have noticed, things have stalled a bit over the summer on the master branches of openrasta and openwrap. While our amazing contributors are still sending pull requests and development has continued, as the owner of the master branches I’ve not been there to maintain the new...

If you’re paying big bucks for those floor-to-ceiling windows why not make them into a canvas for your art as well. Der Kritzler is a motorized plotter that can make this into a reality. It’s a laser-cut pen holder suspended from a pair belt pulleys. Those belts have counterweights, which make...

Monotouch is a powerful tool to create native iOS (iPhone/iPad/iPod) apps written in C# backed by (a native version of) the .net framework. I have been using it for some time now to my great satisfaction. Learning Monotouch was a somewhat bumpy road. The native language for iOS is objective C...

[Tom] sent in a gigantic 3-axis router that he pieced together during a 2 week-long work experience placement. Looking at this picture showing a 12-inch ruler on the work area, we realized that this may be the largest CNC router we’ve seen on Hack A Day. [Tom]‘s employer gave him some obsolete...
