Doing magic with cards involves a lot of precise dexterity to know which card is where. For plenty of tricks, this is often knowledge and control of a single card …read more Continue reading Performing Magic With a Little High-Tech Help
[Stefan] is always looking for a way to make stronger and better 3D prints. His latest experiments involve using a texture on thin plastic parts to increase stiffness. You can …read more Continue reading Texture Adds Stiffness to 3D Parts
Just when it seems like we’ve juiced all the creative potential out of our 3D printers, a bold new feature lands on the table. Enter Velocity Painting, a concept brought to life by [Mark Wheadon] that textures our 3D prints with greyscale images.
At its core, the technique is straightforward: skin an image onto a 3D print by varying the print speed in specific locations and, thereby, varying just how much plastic oozes out of the nozzle. While the concept seems simple, the result is stunning.
Velocity Painting opens up new ways of expression on top of an existing print …read more

Connecting computers to human brains is currently limited to the scope of science fiction and a few cutting-edge laboratories. Tapping into some nerves farther from our central wetware is possible and [Peter Buczkowski] shows us his stylish machine for implanting a pattern into our brains without actively having to memorize anything.
His Medium Machine leverages a TENS unit to activate forearm muscles in a pattern programmed into an Arduino. Users place their forearm across two aluminum electrodes mounted on a tasteful wooden platform and extend a single finger over a button. Electrical impulses trigger the muscles which press the button. …read more

Some people find it hard to look at a huge, flat expanse of floor or ground and not see a canvas. From the outfield grass of a baseball park to some poor farmer’s wheat field, trampling, trimming or painting patterns can present an irresistible temptation. But the larger the canvas the more challenging the composition will be, which is where this autonomous beach-combing art robot comes into play.
Very much still a work in progress, [pablo.odysseus]’ beach bot was built to take advantage of the kilometers-wide beaches left by the receding tides near his home. That immense canvas is begging …read more
