Eirik writes, "I like those old charging docks for mobile phones. But the problem is that you need to buy a new one every time your phone change. And it won't fit if you use a cover on your phone. So I just designed a dock that can be adapted to almost any phone." Read the rest
Julldozer created an amazingly clever digital sundial ("Cadran Solaire Numérique") that precomputes the angle of the sun throughout the day and uses those computations to make hundreds of precise holes calibrated to cast a shadow displaying the present time. Read the rest
Swiss engineer Christoph Laimer has built an open-source hardware, 3D printed watch with a tourbillon mechanism, uploading it to Thingiverse for you to print and assemble yourself. Read the rest

Tom Burtonwood sez, "I have just published Folium, a 3D printed book of bas relief from the Art Institute of Chicago; it's posted to thingiverse for download: 12 pages, 9 scans featuring works of art spanning over 2000 years, from the Ancient Egyptians to Louis Sullivan department store decorations."

Tomorrow, 3/14, is Pi Day in the USA (it will not be Pi Day in the rest of the world until the Martian Emperor subjugates us all to his sinister 14-month calendar). In celebration, Thingiverse user Thor4231 posted this great Eggbot design, ready to be automatically sharpied onto your favorite ovum by means of the wonderful Eggbot printer.
Yesterday at CES, Makerbot CEO Bre Pettis announced three new 3D printers, including a massive, fifth-generation Replicator capable of producing objects that are 45.7cm tall and 30.5cm wide/long. Interestingly, all three new models -- there's also a simple, one-button version and a desktop prosumer version -- sport clear plastic sides. 3D printers are very susceptible to disruption from even slight breezes (the wind cools the plastic between the nozzle and the previous layer) but there's a completely batshit patent on the totally obvious "invention" of putting see-through sides on a 3D printer, so in general printers don't ship with sides, and manufacturers don't publicly advise their customers to add plastic sides to their machines.
Joly sez, "Maker navic09 demos a prototype trainable robotic arm, made from 3d printed parts, an Arduino, and Adafruit analog feedback servos. Inspired by the Baxter robot, this arm can be trained to move with your own hands. Once the train button is pressed, you move the arm and gripper as needed while the Arduino stores the positions in EEPROM. After that the arm will replay the motion as needed."
Life-cycle economic analysis of distributed manufacturing with open-source 3-D printers (paywall link), a new paper published in Mechatronics, examines the cost of common household objects and calculates the projected return-on-investment for a household that buys a 3D printer and makes their own everyday objects, using open design files from sites like Thingiverse, rather than buying them in shops. The researchers concluded that a family could quickly -- in less than "a few years" -- recoup the cost of the printer if they printed their everyday objects. I suspect that the real value of 3D printers isn't simply replacing household objects, but rather, in ushering in new ways of relating to objects -- the same way that email and VoIP don't simple substitute for phone calls, but rather enable entirely different kinds of communications.
