That’s Hemispherical Omnidirectional Gimbaled wheel. As an idea it’s at least as old as 1938, but it’s lately been re-discovered by Curtis Boirum, an MS Mechanical Engineering student at Bradley University in Peoria, IL.
The makers of the Video Experimenter Shield for Arduino have used their product to create an instantly updating word cloud from over-the-air television closed captioning data. The NTSC video is passed through the shield and the Arduino sends the closed captioning text to the computer via serial. The cloud is generated by a Processing sketch, which makes words larger if they’re spoken more frequently.
Check out this faithful reproduction of the Android logo made from an old trash can. The arms are articulated, the eyes are LEDs, and it runs on USB rechargeable batteries.
Tiburcio and his daughter Helena have an interesting tool for learning when an online purchase has been made from their web store — an Arduino-controlled Wario toy. Tiburcio explains: I wanted something nice to have at the office that tell us every time someone make a purchase on our game. Every time we make a […]
Gordon McComb is helping us out on the site this month in support of the release of MAKE Volume 27, our latest robotics issue, and for our monthly Robotics theme here online. Gordon has also just release the fourth edition of his groundbreaking book, Robot Builder’s Bonanza. The first edition of this book was released in 1987 and pretty much launched the hobby robotics field. This was the book that got me into robotics, which lead me into electronics (and Forrest Mims’ book), hardware hacking, and most of my high-tech making interests.
Founded in 1987 in Rocklin, California, Parallax, Inc. manufactures the famous BASIC Stamp microcontroller. The Stamp has been popular among electronics hobbyists since the early 1990s, thanks to such user-friendly features as an embedded BASIC interpreter.
Yury Gitman and Joel Murphy have created a pulse sensor for Arduino: It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart-rate data into their projects. After a few months of testing a gaggle of techniques, we developed what we think is an innovative […]
