[Alex Toussaint] did, and in thinking how such a machine might work he embarked on a path that eventually led him to create a fully functional ultrasonic 3D scanner. In writing it up he’s ...

One way to accomplish this involves four HC-SR04 ultrasonic sensor units that transmit data through an Arduino into a Linux computer. The end result is a virtual touchscreen that can be made at home.

The Arduino has long since proven itself to be one ... as amply demonstrated by this simple but effective homebuilt 3D scanner. While there's not exactly much to guide the rookies out there ...

Arduino may be known for revolutionizing open source hardware platforms, but this week it enters the 3D printer market with the small and affordable Materia 101.

Arduino, maker of the open source hardware platform of the same name, is teaming up with a startup called Sharebot to sell a 3D printer for about $1,000. Announced today, Materia 101 will be ...
