If you have had your computer fall asleep at the worst possible time before you know how frustrating it can be. Todd Harrison from Toddfun.com has come up with a solution. He built a simple battery operated Keyboard Keep Alive Circuit that he stuffed in a cute candy tin shaped like a Wiimote. This circuit closes a relay contact every 25 seconds. Next he connected an interface jack to his keyboard to that the relay can “press” a key when the relay closes. He selected an arrow key but a shift key or something like that would have worked just as well. This circuit would be great to hide inside a keyboard and have it press the caps lock key every 5 or 10 minutes, that would be enough to drive someone mad! If you are looking to solve the same issue there is a device called the mouse jiggler that would do the trick, it is a USB device that slowly (or violently) jiggles the mouse, there is also a neat way to make a DIY jiggler using an optical mouse and a watch.

I have been putting the final touches on the Gear Clock kit which is made up of wooden gears. I have a new appreciation of the effort it takes to make something work well when it is constructed out of wood. MechanicalSculptor makes it look easy! This Parabola project us a true work of art, it’s so smooth and repeatable. His work is a real cut above.

This Autopilot for Aerial Photography slide show that was done for Barcamp Antwerp looks really interesting. “The autopilot has a built in mixer. On first use you need to tell the autopilot what the channel and mixer arrangement of your transmitter/airplane combination is. To put the autopilot in calibration mode, switch on the transmitter, put all sticks in the center and switch channel 6 to “ON”. Now turn on the airplane. View more presentations from kodel.

This Coffee Can Clock is a nice piece of work, there is a good build log and tons of details here at the Wise time with Arduino blog. “The electronics is based on Wiseduino (Arduino clone with DS1307 real time clock on board), with a LED matrix shield sitting on top. The shield is built with 74HC595 shift registers that drive two bi-color (red, green, and orange by subtraction) 8×8 LED matrices.”

This is an inspirational TEDx video of Dennis Hong of RoMeLa. If you think that you recognize his you are right, he was recently chosen as Popular Science’s “Brilliant 10″ for his robotics. “Dennis Hong is an expert in the area of novel robot locomotion mechanisms, design and analysis of mechanical systems, kinematics and robot mechanism design, humanoid robots, and autonomous systems. He is the inventor of the three-legged walking robot STriDER. He was awarded the prestigious Faculty Early Career Development award from the National Science Foundation in 2007.“ |

The Geek Group has acquired a retired KUKA robot. They have made a series of videos about taking it apart to see what makes it tick. Lots of the pieces will be re-purposed into other projects that they have on the go. That is one massive robot, I would have preferred to see it brought back to life but it is also interesting seeing how all the bits and pieces interact. We have seen lots of fun things that can be done with KUKA robot arms, there was the Ice Cream Making Robot, the KUKA DJ Robot, and of course all the fun rides made from robot arms!
