A Fountain of Superhydrophobic Art

Superhydrophobic coating finds a new application in art through [Arthur Carabott] in the form of a bizarre fountain.

A Master’s student in the Global Innovation Design course at the London Royal College of Art, [Carabott] achieved the effect by leaving parts of the laser-cut acrylic untouched by Rust-oleum’s NeverWet Multisurface coating. A 3d printed spigot mounted high above the surface imparts greater velocity to the impacting water so as it hits the acrylic the liquid forms into channels giving the impression of something surreal. Indeed — his design is inspired by the optical illusions of Japanese mathematician Kokichi Sugihara which …read more

Think Globally, Build Locally With These Open-Source Recycling Machines

Walk on almost any beach or look on the side of most roads and you’ll see the bottles, bags, and cast-off scraps of a polymeric alphabet soup – HDPE, PET, ABS, PP, PS. Municipal recycling programs might help, but what would really solve the problem would be decentralized recycling, and these open-source plastics recycling machines might just jump-start that effort.

We looked at [Precious Plastic] two years back, and their open-source plans for small-scale plastic recycling machines have come a long way since then. They currently include a shredder, a compression molder, an injection molder, and a filament extruder. The …read more

Tiny Open Source Robot

We watched the video introduction for this little open source robot, and while we’re not 100% sure we want tiny glowing eyes watching us while we sleep, it does seem to be a nice little platform for hacking. The robot is a side project of [Matthew], who’s studying for a degree in Information Science.

The robot has little actuated grippy arms for holding a cell phone in the front. When it’t not holding a cellphone it can use its two little ultrasonic senors to run around without bumping into things. We like the passive balancing used on the robot. Rather …read more
