Environmental Waste Transformed into Art

In an American town devastated by toxic draining, a partnerships between university professors, conservationists, and artists, toxic waste is being transformed into pigments. Here’s more from COLOSSAL:

In southeast Ohio, toxic drainage from abandoned coal mines has devastated streams and rivers. The acidic sludge, which is filled with heavy metals, leaches into waterways, destroying ecosystems and turning what should be clear, bluish waters into murky, rust-colored runs. In Athens, home of Ohio University, a Hocking River tributary known as Sunday Creek is a prime example of mining’s harmful effects, with more than two million pounds of iron oxide pouring into the stream each year  A new documentary directed by Jason Whalen visits the area and the team vowing to clean it up.

“Toxic Art” follows an unconventional pairing of two Ohio University professors who have teamed up on a project that turns sludge from the stream into pigments for oil paint. A project of the global conservation organization Rivers are Life, the short film shares the story of artist John Sabraw and Guy Riefler, the chair of the Civil Engineering department, who have spent six years developing pigments using iron oxide they collected from the creek.

Bringing KITT from Knight Rider to life using ChatGPT and a Raspberry Pi 4

The Knight Rider Historians’ YouTube channel recently showed off an excellent KITT replica that uses a Raspberry Pi and ChatGPT to work as an interactive prop.

This KITT prop is designed to resemble the voice box from the car. It listens for audio input and processes it using speech-to-text so that the data can be parsed to ChatGPT. From there, ChatGPT generates a response in the way KITT would speak. This text is then transposed into audio played while the LEDs flash to mimic how they would flash on the original show.

They use a Raspberry Pi 4 to control the operation. It’s connected to a USB mic and USB speaker for audio input and output.

Custom Handheld Pi Zero HQ Camera @Raspberry_Pi #PiDay #RaspberryPi

If you’ve ever run around at the magic hour snapping shots with a Pentax K1000 or a Canon AE-1, then you know the great low-fi analog feel of an old timey camera. Today’s version of that might be something like this design from Jacob Cunningham. Here’s more from hackaday:

Inside the 3D printed enclosure is a Raspberry Pi Zero, a Pi HQ Camera module, an 1.5″ OLED display, a lithium-ion battery pouch cell, and the charging and voltage regulation boards necessary to keep everything powered up. There’s also a handful of tactile buttons to work through the settings and menus, and a 10-axis IMU to help you keep your horizon level.

…

The hardware side of things looks more or less complete, at least for a first version, and [Jacob] has provided everything you’ll need to build one of your own. But the software is still a work in progress, with the latest push to the Python code in the project’s GitHub repository just eight hours old at the time of this writing. If you’ve been looking for a DIY camera project to really sink your teeth into, this could provide a great starting point.

See project!

Raspberry Pi Foundation Research Seminars #Raspberrypi

SCRATCH CONF240819 916

The Raspberry pi research foundation hosts monthly free online seminars about computing education research that you can participate in! You can catch up on past seminars on the Rasperrypi.org blog and on their previous seminars and recordings page. Last months seminar was all about understanding the impact of AI tools in the classroom. Via Rasperrypi.org

Educators around the world are grappling with the problem of whether to use artificial intelligence (AI) tools in the classroom. As more and more teachers start exploring the ways to use these tools for teaching and learning computing, there is an urgent need to understand the impact of their use to make sure they do not exacerbate the digital divide and leave some students behind.

Sri Yash Tadimalla from the University of North Carolina and Dr Mary Lou Maher, Director of Research Community Initiatives at the Computing Research Association, are exploring how student identities affect their interaction with AI tools and their perceptions of the use of AI tools. They presented findings from two of their research projects in our March seminar.

Raspberry Pi NAS #RaspberryPi #PiDay

Great build and tutorial from Frank Bernhardt.

When I decided to replace my old NAS with a new one, I didn’t want to spend too much money on this. So I looked around and found that there are many NAS kits based on a Raspberry Pi. Now you may ask what was my motivation to create another one instead of choosing one of the existing NAS models? This is quite easy to answer. None of these available models matched my requirements for 100%. And I also enjoy developing new things …

The Strange Creatures in the Work of Spencer Hansen #ArtTuesday

Some art galleries feel as sanitized as hospitals, as quite as libraries, and as devoid of fun as an SAT test room. But any museum filled with the work of Spencer Hansen will feel a lot more like F.A.O. Schwartz at its playful heights. Here’s more from COLOSSAL:

Sporting pinecone-esque suits or masks with gilded antennae, the alien creatures that surface in Spencer Hansen’s Bali workshop appear to be both of this world and not. The artist…recycles familiar, natural materials like wood, fur, and bone, envisioning mysterious but friendly characters with skeletal features and chiseled bodies. Ranging from a few inches high to life-sized, the uncanny sculptures are part of an ever-growing universe salvaged from the scraps of waste materials…. A statement about the exhibition describes his childhood as a major influence on this body of work, explaining:

Spencer was born in rural Idaho, the youngest of eight children. As a child, he found solace in daydreaming. His imagination offered relief from the confusing stories that knit together his family’s deep religious beliefs. He formed his own narratives in a world he belonged to, an internal landscape inhabited by creatures. His world shaped by stories, so closely tied to his identity, is the foundation of his sculptural works.

Xylem Arbor #ArtTuesday

Centene Artwork 1 2048x1534

Nervous System is a generative design studio located in Palenville, NY. They have created their first large scale public artwork composed of over 200 unique lasercut aluminum leaves. Via the Nervous System blog

We recently created our first large scale public artwork. Soaring to a height of 120′, Xylem Arbor is an aggregation of bent metal leaves that climb up the atrium walls of the TEN30 corporate campus in Charlotte, North Carolina. The shape and pattern of the metal leaves evolves as the sculpture ascends. Each leaf features an intricate perforated pattern which is algorithmically generated based on simulations of natural processes.

The Xylem Arbor explores patterns of circulatory systems in plants and throughout the biological world through the lens of science and computation. The sculpture is composed of 224 unique aluminum panels which span the 120’ atrium space. As you travel up the building, the patterns, shapes, and colors morph, evoking different structures from the natural world from lily pads to coral and leaf veins to dragonfly wings.

In nature, the closer you look, the more you can discover, and we want our designs to convey that same sense of wonder. This piece expresses our fascination with multi-scale structures, combining fabrication with geometric logic, and exploring new computational techniques.
