[Theo Kamecke] is an artist who produces striking pieces using printed circuit boards. We’ve seen PCBs used as faux stained-glass before, but [Theo’s] craftsmanship stands apart from everything we’ve seen. His webpage has at least one piece that sites the usage of vintage 1960’s circuit boards, but we wonder if he doesn’t design some of these to suit his work. Either way, we’d love to see him take on the finish work for that mechanized expanding round table we saw back in June. See more of his work on his photostream.
Want to clean up the Gulf of Mexico oil spill in one month? Seaswarm says it can be done with 5000 floating robots.
As the name implies, the project uses swarm robotics. Each unit draws power from the sun, and drags around a conveyor belt of oil absorbent nanofabric that doesn’t get wet in water. Once the fabric is saturated with crude it can be removed using heat; not a task the swarm can do by itself. But get this: after separating oil from nanofabric both can be used again. That means you get the environmental benefit of cleaning up the Gulf, not throwing away your collection medium, and the oil is once again a usable commodity. Sounds like a lot of high promises, but take a look at the video after the break and decide for yourself.

[Whoopjohn] decided to build a driver board for a display he pulled from a pinball machine. You’ve probably seen these used to scroll both score and messages using a total of sixteen 15-segment digits. We’d love to get our hands on one, and you might too but where? [Whoopjohn] notes that these were usually installed two-per machine and the driver boards were run close to their maximum ratings. That means that somewhere there’s a collection of broken machines with working displays. If you do plan to make this happen, you should be able to figure out the circuit based on this commented board layout (pdf).
Like the Grand Theft Auto RC missions come to life, this helicopter can grasp objects for transport. They don’t have to be a special size or shape, and it can lift them even if they are not centered. This is thanks to a load-balancing hand (originally developed as a prosthesis) that relies on flexible joints and a tendon-like closing mechanism. As you can see in the video, the light-weight chopper has an on-board camera so that the operator can see what is being picked up. This little guy has no problem lifting objects that are over one kilogram while remaining stable in the air.
