[Viktor] doesn’t remember why he started this project. He doesn’t know what he had in mind in the beginning, nor what the intended use was.He knows he wanted something interactive with blue LEDs.  What he ended up with, was a 3 axis Accelerometer with a pretty cool display that sits on his desk to amuse visitors. [...]

Hackaday doesn’t always get the entire back story of a build. The usual assumption is that someone decided to build something, and with just a little bit of effort the project makes it into the Hackaday tip line. This doesn’t do justice to the builder, with skills honed after years of practice and experience. A 200-word summary is deceiving, and [...]

Check out this 6-pin MSP430 microcontroller. What’s that you say? TI doesn’t make a 6-pin MSP430? True, Texas Instruments doesn’t make one, so [Greg] grabbed his Demel and a cutoff wheel, and chopped up a larger uC to arrive at this package. It may sound a bit crazy at first, but when you think about [...]

[bunnie] is up to his old tricks again. He successfully implemented a man-in-the-middle attack on HDCP-secured connections to overlay video in any HDMI video stream. There’s a bonus, too: his hack doesn’t use the HDCP master-key. It doesn’t violate the DMCA at all. HDCP is the awful encryption scheme that goes into HDMI-compatable devices. Before [...]

We’re guessing that if you ever though of buying an arcade cabinet it was only briefly, and you decided against based on the difficulties of moving and finding a place for such a large and heavy item. You could go the opposite way and build a controller for a  MAME box, but for some, there’s [...]

[Pete] has an iPhone 4s and loves Siri, but he wishes she had some more baked-in capabilities. While the application is technically still in beta and will likely be updated in the near future, [Pete] wanted more functionality now. Since Apple isn’t known for their open architecture, he had to get creative. Knowing how Siri’s [...]

[Thierry Legault] doesn’t just look up at the stars, the uses a motorized telescope base of his own making to track and photograph secret objects orbiting the earth. What do we mean by ‘secret objects’? Spy stuff, of course. Last month he captured some video of the X-37B, an unmanned and secretive reusable spacecraft (read: spy [...]

After a motorcycle accident that cost him is arm [Martin] and his son [Luke] chose not to give up. They used their considerable mechanical skills to create a replacement robotic arm which allowed Martin to start doing some of the simple things he had been unable to do with the prosthetic he was originally fitted [...]

This doesn’t have the flashy futuristic appeal that we’d like to see from high-tech robots, but this amphibious wanderer is well suited for it’s intended purpose. It was developed by researchers at the University of Minnesota to navigate mostly wet environments, collecting data about water quality as part of a distributed army of sensor bots. [...]

Instructables user [Jones Electric] has been quite busy lately, building a radio-frequency range finder. Built as part of a German youth science competition, he and his partner built a pair of transmitter/receiver modules that can be used to measure distances of up to a mile (~1.5km). Their argument for radio-based rangefinders is that laser rangefinders [...]

[Daniel] wanted his child to stay in bed until a semi-decent time each morning. The problem is the kid doesn’t know how to read a clock, so [Daniel] built him a clock. Yeah, doesn’t make much sense to us either, but we’ve used our own shaky premises for projects so who are we do judge? [...]

While hacking a wireless presenter doesn’t sound like something worthwhile or interesting, [Niels Teusink] demonstrates that these little devices often are a lot more powerful than we give them credit. With an Arduino, plenty of research, and some heavy sniffing of a wireless presenter’s SPI and then wireless interface [Niels] is able to emulate an [...]

We’re all for putting a GPS where it doesn’t normally go, but we’re not sure [Roberto's] version* is the best of locations. Take for example [Jair2k4's] GPS. It doesn’t block out 50% of his vision of the road and the impending accident in front of him. Regardless, the solid aluminum and seamless mounting really does make [...]
