Bottle opener ring for bartenders

Dustin Wallace, whose Oriboto Robotagami I am always raving about, also makes this wicked-looking wearable bottle opener intended for beverage-slangin’ professionals. You can wear it on the top or bottom of your palm. It’s good-looking, provides plenty of leverage, and seems like it might come in handy when the guys in black cowboy hats start smashing bottles over people’s heads.

If you follow CRAFT, as well, you may have seen Rachel’s post back in January about Oregon jeweler Shannon Conrad’s interlocking Lego rings. Shown above is the result of Shannon’s very first experiment with casting from Lego elements, a one-off solid silver Imperial Stormtrooper minifig she made for her 11-year-old son.

University of Rochester Associate Processor Chunlei Guo has developed a technique that uses a femtosecond laser to blast nanoscale features into the surface of a piece of metal–pretty much any metal. These tiny features interact selectively with white light to reflect a particular color–pretty much any color. It’s also possible to achieve a near-perfect black finish and iridescence. If the process can be made economical (it’s very slow at present, requiring about half an hour to treat a dime-sized area), it could be a complete game-changer when it comes to finishing metals. Guo gives the example of a bicycle factory that could use only a single laser to make parts of any color or color scheme.
