This panda doily from Ravelry user Chinami Horiba is just about the cutest thing I’ve ever seen! Fair warning: The pattern is available for free, but to get it you’ll have to jump through a few Facebook-related hoops after you click through the link on Ravelry.
I love Dane Kouttron’s monster 3D printer! This project documents the re-purposing of a ‘rescued’ 1980’s IBM 7575 SCARA Robot Arm, into a functional 3D ABS printer. The project features some motor upgrades [listed earlier], documentation of encoder positioned motor control feedback theory, the interminglings of EMC2 [Linux CNC], heated workspace construction and a step […]
21-year-old MIT computer science and electrical engineering student Stephan Boyer built Bullet, a self-balancing electric unicycle that reaches a top speed of 15 miles per hour and is the envy of his peers.
Alasdair Allan, author of iOS Sensor Apps with Arduino, is presenting an iOS Sensors and External Hardware Masterclass in London in October: This one day course will guide you through developing location aware applications for the iOS platforms that make use of the onboard sensors: the 3-axis accelerometer, the magnetometer, the gyroscope, the camera and […]
20 DIY’ers from around the United States gathered at Derek Diedricksen’s off-the-grid camp in Vermon’t’s North East Kingdom for a weekend workshop on tiny house building.
Over on the Shutterstock blog, Byron Hudson and Kathy Cho share some tips and a how-to for creating and adding some 3D-summery font effects to your next design project.
