A Machine That Paints What It Hears

Check out this incredible Interactive Robotic Painting Machine by artist and composer Benjamin Grosser. The machine takes in sound as an input and outputs paintings: This machine uses artificial intelligence to paint its own body of work and to make its own decisions. While doing so, it listens to its environment and considers what it hears as input into the painting process. In the absence of someone or something else making sound in its presence, the machine, like many artists, listens to itself.

All-Glass Steam Engine

Czech maker Michal Zahradník built this steam engine entirely out of blown glass. The crankshaft is glass. The piston is glass. The counterweight that makes the wheel spin evenly is glass. Imagine that everything is made out of glass. * There are no sealants used. All is accomplished by a perfectly snug fit. The gap […]

Robotic Fish Uses only One Servo

Robotic Fish Uses only One Servo

At the Center for Biorobotics in Estonia, Eszter Ozsvald built a mechanical fish named A.riel that can model the movements of actual fish surprisingly well, and using only one servo inside a carefully made silicon-based mold. It took many iterations before the final product, but found that in the end she could develop the same vortex patterns as actual fish. Her site has extensive documentation on the build process and is definitely worth a look for the mold-making processes alone.

What’s this kind of joint called?

What’s this kind of joint called?

I have built a couple of laser-cut and CNC-routed kits, recently, that use this clever arrangement of tabs, slots, and a couple bits of cheap hardware to securely butt one panel against another at a right angle. One panel has a pair of rectangular ports with a round hole in between, and the other has a matching pair of tabs with a smaller T-shaped slot between. In use, the ports receive the tabs and a screw passes through the round hole and along the upright of the T to mate with a square nut captured in the arms of the T. There are many possible variations and the technique has lots to recommend it from a manufacturer’s standpoint.
