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 attempt to realize the impossible artwork of M.C. Escher. The effect is worthy of a double take.

How To Keep An Unruly Dryer In Line

If necessity is the mother of invention, then inconvenience is its frustrating co-conspirator. Faced with a finicky dryer that would shut down mid-cycle with a barely audible beep if its load was uneven (leaving a soggy mass of laundry), [the0ry] decided to add the dryer to the Internet of Things so it could send them an email whenever it shut itself down.

After opening a thinger.io account, adding the soon-to-be device, and setting up the email notification process, [the0ry] combined the ESP8266 Development Board, a photosensitive resistor, and a 5V power supply on a mini breadboard. All that was left was to mount it on the dryer and direct the LDR (light-dependent resistor) to the machine’s door lock LED to trigger an email when it turned off — indicating the cycle had finished or terminated prematurely. A little tape ensured the LDR would only be tripped by the desired light source.

If you’re an apartment-dweller have WiFi in the wash area it would be awesome to see a battery-powered version you take with you. But in general this is a great hardware blueprint as many device have status LEDs that can be monitored in a similar way. If you want to keep the server in-house (literally in this case) check out the Minimal MQTT series [Elliot Williams] recently finished up. It uses a Raspberry Pi as the center server and an ESP8266 is one of the limitless examples of hardware that plays nicely with the protocol.

We love seeing hacks like this because not only does it conserve water and energy by reducing instances of rewashing, but it’s also a clever way to extend the life of an appliance and potentially save hundreds of dollars in replacing it. Add this to the bevvy of hacks that add convenience to one’s home — some of which produce delicious results.

A Robot In A Day

While building a robot (nearly) from scratch isn’t easy, it needn’t be a lengthy process.  Is it possible to build a bot in a single day? With some musical motivation (a 10 hour loop of the A-Team theme song), [Tyler Bletsch] answers with a resounding ‘yes’ in the shape of his little yellow robot that he built for a local robotics competition.

Designing and fabricating on the fly, [Bletsch] used Sketchup to design the chassis, and OpenSCAD to model the wheels while the former was being 3D printed. Anticipating some structural weakness, he designed another version that could bolt to wood if the original failed, but the addition of some metal support rods provided enough stability. Mouse pad material gave the wheels ample traction. An Arduino with the L298 control module receives input via an HC-06 Bluetooth board. Eight AA batteries provide 12V of power to two Nextrox mini 12V motors with an integrated voltmeter to measure battery life.

The Unity of Dance and Architecture

In an ambitious and ingenious blend of mechanical construction and the art of dance, [Syuko Kato] and [Vincent Huyghe] from The Bartlett School of Architecture’s Interactive Architecture Lab have designed a robotic system that creates structures from a dancer’s movements that they have christened Fabricating Performance.

A camera records the dancer’s movements, which are then analyzed and used to direct an industrial robot arm and an industrial CNC pipe bending machine to construct spatial artifacts. This creates a feedback loop — dance movements create architecture that becomes part of the performance which in turn interacts with the dancer. [Huyghe] suggests an ideal wherein an array of metal manipulating robots would be able to keep up with the movements of the performer and create a unique, fluid, and dynamic experience. This opens up some seriously cool concepts for performance art.

Master’s UAV Project Takes Flight

Pushing the maker envelope all the way to the Master level, [Przemyslaw Brudny], [Marek Ulita], and [Maciej Olejnik] from the Politechnika Wroclawska in Poland packed a UAV full of custom sensor boards for their thesis project.

The Skywalker X-8 FPV drone underwent extensive modifications to accommodate the embedded systems as well as upgrading the chassis with carbon glass to withstand the high load and speeds they would need to perform their tests. The ailerons were customized for finer control of the drone. But for our money, it’s all the board design that supports those sensors which is really fun to delve into.

From Rusty Cargo Van to Mobile Studio

Looking for a more unique living experience, [Zach Both] converted a 2003 Chevy Express Van he picked up from Craigslist into a gorgeous mobile home.

The van had 200,000 miles when he bought it. The body and frame were a bit rusty, but he saw the potential. First step was gutting the entire van, and getting rid of any surface rust with an angle grinder. It was a long and tedious process, but once it was done he had a blank slate to work with.

Mind Control Cerebro Helmet Controls People

For the recent release of X-Men Apocalypse, YouTuber [Allen Pan] from “Sufficiently Advanced” decided to make a rather ambitious project — a working Cerebro Helmet. Wait what?

When worn, it allows you to steer the person wearing it to the left or right using a series of impulses to the brain. It’s actually a well-researched technique called Galvanic Vestibular Stimulation — basically if you zap a nerve in your ear it messes with your balance. If you’re trying to walk in a straight line and the electrodes trigger, it causes a sudden imbalance and you tend to lean in that direction — thus changing the direction you are walking. Kind of like remote control cockroaches — but… with people…
