Join Table by Ding 3000
Ancient Puzzle Meets Modern Table Inspired by Japanese puzzle games, this simple table solution, appropriately named JOIN, can be assembled in a matter of minutes (without any tools!) by linking its 3 oak legs into a combination devil’s knot. JOIN table travels as a part of the “Design Deutschland 2011″ exhibition – curated by the German Design Council – from the FuoriSalone in Milan to the ICFF in New York and finally to the Business of Design Week in Hong Kong. Tour dates: - Milan, FuoriSalone, Spazio Carrozzeria, Via Tortona. 12-17 April 2011 - New York, ICFF International Contemporary Furniture Fair, 14-17 May 2011 - Hong Kong, Business of Design Week, 1-3 December 2011 Designer: Ding 3000

How to Build a Marble Machine
The centerpiece for this marble machine are the gears. They lift dozens of marbles at a time and send them down an amazing track of twists and turns. At first glance I thought this creation was some sort of wooden gear clock. If you go to the project site (click on the image) you will find an array of chutes and barrels and other things for the balls to do on their way down. It inspires me to think about designing a clock that has a marble run aspect. I have seen some marble machines that are built to tell the time. I counted the Ball Bearings in the gears.
Make a DIY George Nelson-Inspired Outdoor Slat Bench | Man Made DIY | Crafts for Men
When my neighbor, Gina, moved in next door, a standalone porch swing appeared on our shared patio. The thing was at least thirty years old, and had been outside for just as long, and showed the wear of snowy winters, blazing hot summers, and all the rainy days in between. Not that it was likely much to look at when it was new. It was, in every way, an eyesore. But, my goodness, if that thing wasn't useful. Then, Gina did the unthinkable: she got married, had a baby, and moved away. So, I figured it was time to make some outdoor seating of my own. Wanna make one, too? Note: Yes, I have a collection of power tools, and used them on this project. Designing and materials. The most helpful resource were the official pages at Herman Miller and DWR. A note about cedar: Nelson's design is made of hard maple, and for good reason: it's very strong, and has a straight grain pattern that allows the wood to be milled flat, essential for this geometric design. Milling the slats and rails. The legs.
I want sparks & I want them NOW!
Update May 2003 - Marx Three is now up & running Do you like the idea of tesla coils and other high-voltage sparking stuff, but don't have the time, money or patience to build something that elaborate? Here's a fun little project that can make big, fat, noisy sparks at least 2 inches long, and can be built very quickly and cheaply. The Marx generator consists of an array of resistors, capacitors and spark gaps arranged as follows: The capacitors, C, are charged up in parallel via the 1M (one megohm) resistors, so they each become charged to the input voltage. Rb has a ballasting effect. Although it is possible to make a Marx generator with just an array of resistors, capacitors and spark gaps, it can be hard to make it fire reliably, as it will depend on the breakdown voltage of the spark gaps, and there can be a fine line between not firing and firing before all the capacitors are fully charged. Component choice An input voltage of about 4-8KV is recommended. Power supply "Marx Two"

How One Teacher Turned Sixth Grade Into An MMO
Editor’s Note: Ben Bertoli is a long-time Kotaku reader and commenter, a lifetime, dedicated video gamer and a sixth-grade teacher in Indiana. He reached out to Kotaku this past week to share the story of how he turned his class into a role-playing game. The enthusiasm and motivation of the children in Bertoli’s class evoke the success stories seen in gamified experiences such as Fitocracy. Here, Bertoli explains his creation, ClassRealm, how it works and what motivated him to develop it. Video games and education. I wouldn’t be as well read as I am today if it wasn’t for video games. As I was describing my video-game-related teachings to my buddy Courtny, we began talking about incorporating gaming into education. I worked on my classroom system for a month before I had it completely devised. Knowing I could get some supportive and insightful feedback I even ran the idea by my pals on Kotaku. 1. Many students were thrilled right off the bat. Participation skyrocketed on the first day.
