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...

Sometimes, not all our builds work out the way we hoped. That’s what happened to [Rob] and his attempt at a Delta robot that does stereo lithography. A Delta robot is capable of very fast and precise movements, so [Rob] slapped a laser module on the end of the arms. After putting some UV curing...
