The Hackaday Prize: Unofficial Statistics

Hackaday Prize entries over time. You people really know how to procrastinate. Click to embiggen.

What is the Hackaday crew doing this weekend? Judging Hackaday Prize entries, of course! We need to pare down the hundreds of entries we received to 50 primo entries for the quarterfinals round. We™re going to be slammed the entire weekend, so don™t expect any news on who™s in and who™s out of the competition until Monday.

Each of us has about 15 hours of video to go through (multiply the number of entries by two minutes. It™s a lot), and of course we need ¦ Read the rest



Introducing Hat a Day! Not to be Confused With the Real HaD of Course¦

With the release of the Raspberry Pi B+ model comes a whole slew of extra GPIO connectors, a whopping 40 of them in fact ” Almost double the original B model! A HAT stands for Hardware Attached on Top, and Adafruit is celebrating by trying to create a new hat, every day.

A HAT is a rectangular board measuring 65x56mm with mounting holes for the Raspberry Pi B+ and a 40 pin GPIO header. That doesn™t sound too special by itself, but two of the header pins are reserved for a special auto-configuration system that allows your Pi to ¦ Read the rest



Stewart Platform Ball Bearing Balancer

For their Mechanical Engineering senior design project at San Jose State University, [Tyler Kroymann] and [Robert Dee] designed and built a racing motion simulator. Which is slightly out of the budget of most hackers, so before they went full-scale, a more affordable Arduino powered Stewart platform proof of concept was built. Stewart platforms typically use six electric or hydraulic linear actuators to provide motion in six degrees of freedom (6 DOF), surge (X), sway (Y), heave (Z), pitch, roll, and yaw. With a simple software translation matrix, to account for the angular displacement of the servo arm, you can ¦ Read the rest

Fear and Loathing at DEFCON 22

Nothing says œWelcome to Vegas like a massive turbulence on a plane full of drunk people who, instead of holding on to their seats, frantically laugh and shout œwe™re all going to die! At 105 Fahrenheit outside, the heat was getting into everyone™s head. After a bumpy touchdown, the in-flight entertainment system rebooted, and a black terminal screen flashed onto everyone™s face:

RedBoot(tm) bootstrap and debug environment [RAM] (MAS eFX) release, version ("540060-212" v "0.1.02") - built 12:00:35, Nov 19 2004
