Mcor Technologies recently launched a brand new rapid prototyping machine. The Mcor Matrix forgoes the standard of expensive and rare build materials by using A4 office paper. The machine selectively deposits glue on the sheet of paper: more glue on the cross-section, less on the waste. It then uses a blade to cut out the part profile. The vertical resolution … Read the rest

Official Arduino ethernet shield
November 6, 2008 By 16 Comments
Arduino has just released an official ethernet shield. It’s based on the same WizNet W5100 chip that was used in the tiny ethernet board we covered earlier. The W5100 handles the full IP stack and can do TCP or UDP with four simultaneous sockets. The board has a power indicator plus six LEDs to debug the connection. It works … Read the rest
Design robots to hunt humans

The Department of Defense wants you to design a pack of robots that would hunt humans. Or, as they put it, “search for and detect a non-cooperative human subject”. While the project brings to mind Terminators, there are also non-terrifying uses for these robots, including search and rescue missions. The robots should be about 100 kilograms or less, provide immediate … Read the rest
Install OSX on the HP TouchSmart
November 6, 2008 By 8 Comments
[Aaron Nelson] of Hijinks Inc. wrote up how he installed OSX on his HP TouchSmart IQ507. It looks and works like you would expect, save for a few things. The touchscreen works, but the calibration is so far off it’s useless. The most important things, like ethernet and the memory card reader, work fine. [Nelson]‘s biggest frustration is that … Read the rest
Gyro controlled game
November 6, 2008 By 4 Comments
[Eric] sent in this cool project that he did as part of his graduation project. He built a game that uses a gyroscope as an input device. For the gyroscope, he’s using a Powerball with a sensor inserted into it. This data is gathered by an Arduino in a pretty enclosure. The whole unit connects to a PC via … Read the rest
