Space Images are Space Art #SpaceSaturday

Outer space exists mostly in our imagination. The photos created from James Webb data, the new way we see black holes, even the new colors we associated with Jupiter are all augmented, composited, and, in a way, created as works of art. It likely isn’t true that Stanley Kubrick shot a faked moon landing, but he certainly contributed to the way a generation of filmgoers imagine outer space, alien intelligence, and what a trip to Jupiter might look like. All space images are art. Here’s more, from Aryo Toh Djojo via JUXTAPOZ:

Outer space and alien life forms hasn’t always been the topic for fine art. We have seen a renwed appreciation for the likes of Sorayama, Giger and Amano in recent years, but the idea of putting flying saucers and images of space onto canvas is a bit of a challenge. But in the studio of Los Angeles-based Aryo Toh Djojo, and in his new solo show Unseen Realities at Stems in Paris, we look beyond our expectations for the content in gallery work and start to look to the skies above. Aryo doesn’t always touch on space as a subject, but he often has gazed skyward and created work that exists above the horizon and into the things we cannot deny influence and fascinate us. In this show, he creates an interstellar vision of life, with moons, hybrid creatures, voids and bright monoliths. We are on earth at times but also just beyond, touching on something both human and explorative.

Raspberry Pi Hat Camera

Who needs a [I won’t name it but you know what I’m walking about] when you can just use a Pi?

via Tom’s Hardware

Many of the Raspberry Pi boards are well known for having a notably small form factor. The Raspberry Pi Zero 2 W is a tiny, yet powerful board o it’s not surprising that when maker Jacob David C Cunningham needed something small and lightweight to power his hat clip camera project, he chose it. This device works by clipping to the bill of your hat (not your usual Best HATs for Raspberry Pi) and captures both images and video using an official Raspberry Pi camera module connected to the Pi.

Building an interactive plotter art installation #Art @toThePixel

James Merrill, given the opportunity to participate in SIGGRAPH 2023 in Los Angeles, decided to showcase how art, code, and pen plotters all mesh together. In order to do this, he created an interactive art installation which brought together all three.

Building an interactive art installation requires careful planning and application architecture. In this post, I will explain my decisions and how I arrived at them.

My design goal was simple: A person can walk up, play with a MIDI controller, see a resulting image on a screen, and then send the image to a pen plotter. The plotter draws their unique drawing, and they can take it home and frame it.

I evaluated a few options for input devices. I landed on the Intech Grid series MIDI controllers for their simplicity and modularity. Meant to be snapped together, these controllers offered the correct number of inputs to encourage playful exploration without being overwhelming.

Participants created over 230 drawings.

Technologies used:

  • P5.JS
  • Canvas
  • Lua
  • Svelte
  • React
  • React Native
  • MIDI
  • Eleventy
  • Postgres
  • Digital Ocean App Platform

Adafruit BrainCraft HAT – HackSpace Magazine Issue 76 #BrainCraft @HackSpaceMag @Raspberry_Pi

HackSpace Magazine Issue 76 features the Adafruit BrainCraft HAT for Raspberry Pi:

According to Adafruit, the BrainCraft HAT “allows you to “craft brains” for machine learning on the edge, with microcontrollers and microcomputers”, and we really like that description.

The board features a 240 × 240 TFT IPS display for inference output, a camera connection slot, joystick, button, left and right microphones, stereo headphone out, a 1-watt speaker output, and three RGB LEDs. And, to make building up your circuit simple without the need to solder, they even included two 3-pin STEMMA connectors. Just add your Raspberry Pi and you’ll be off to the races.

There are a few more well-thought-out features of the BrainCraft HAT, like the ability to add a fan under the HAT to keep your Raspberry Pi cool when running AI inferencing. Head over to the Adafruit website to learn more about this very capable little HAT.

They rate the HAT 9 out of 10, saying “Brains for your Raspberry Pi.”

Small scale pen plotting #ArtTuesday #Art

Adam Fuhrer posts:

After creating pen plotted art for just over a year now, I decided to explore a new format for my work by altering the scale of the artworks. The pieces (above) are created in Inkscape, utilizing a variety of its built in tools, most notably path effects and various modes for object displacement.

Once the piece is finalized, the SVG file is sent to an AxiDraw V3/A3 and plotted on smaller-scale 4×6″ paper using Rotring Isograph pens, with varying line thicknesses from 0.20mm to 0.80mm. Many of the pieces below are available for purchase (in a slightly larger size) through my shop.

Neuron and Mycoplasma puzzles with art by David S. Goodsell #ArtTuesday @nervous_system

Two new biology themed puzzles from Nervous System feature the artwork of scientist/artist David S. Goodsell, whose intricate, vibrant watercolor paintings explore the dense landscape of machinery that powers the cell.

The Neuron Puzzle (423 pieces, $120) dives into the structure of an axon. That’s the part of a brain cell that carries electrical impulses to communicate with other cells. There’s also the Mycoplasma Puzzle (134 pieces, $50) a small puzzle which looks at one of the simplest known living organisms, Mycoplasma mycoides. Measuring only 300 nm this bacteria is the prototypical example of what makes life and you can see every element of it rendered in colorful detail in the puzzle. We explored some new puzzling tricks in each of these puzzles like alternate solutions and interior boundaries.

Both the Neuron and Mycoplasma puzzles feature interior cut lines that form macro design elements across the entire puzzle. The Neuron features an idea we’ve had for a while, which is a hierarchical puzzle, a puzzle of puzzles. The Mycoplasma puzzle features partial circles embedded in the cut. The breaks in the circles allows the pieces to naturally interconnect in the cracks and adds a little trickiness to where a circle might appear.

A Pet Monitoring Device @Raspberry_Pi #PiDay #RaspberryPi

Pets can wander. We like it when they wander. We’re charmed by their wandering even as we, sometimes, wish that we could wander as much as our furry friends. That said, sometimes we want to be informed where our pets wander. To that end, Hao on hackster has come up with a project that uses Seeed XIAO ESP32S3 Sense, Raspberry Pi 4, Homeassistant, ESPhome, Mosquitto, and YOLOV8 to create a pet monitoring device. Here’s more!

In this project, I have integrated the Seeed XIAO ESP32S3 Sense into the homeassistant platform via WIFI, turning it into a monitoring module that seamlessly integrates into the home internet system. Additionally, it supports automatic pet recognition beyond its basic monitoring function. We can deploy it in areas where we don’t want our pets to enter, such as the kitchen or an open balcony. When the pet enters the designated area and is captured by the camera, homeassistant can promptly send push notifications to our mobile devices. It can also trigger other actions, such as playing sounds or activating toys, to attract the pet to leave the area.

Get started on your own Raspberry Pi LED sign #RaspberryPi @slashgear

Programmable LED signs retail anywhere from the $200 range to more than $2,700, depending on size and capability. Considering the cost, it’s understandable why many people might opt to make their own signage using a Raspberry Pi.

The essential parts required for your Raspberry Pi LED sign include an LED matrix, an RGB bonnet or Pi HAT (Hardware Attached on Top), an appropriate power supply, and some material to construct the housing.

If you want to use many colors, you’ll need to purchase an RGB LED matrix. These come in different sizes, such as 16×32, 32×32, 64×32, 64×64, and more. Matrix panels are comprised of several LED lights laid out in symmetrical rows, and multiple panels can link together to create even more extensive displays. These panels run anywhere from $15 up to over $60 and are available from various manufacturers.

The Internal Workings of the Human Body Realized in Sculptures #ArtTuesday

If you’ve seen eXistenZ, or Dead Ringers, or Crimes of the Future, you’re familiar with the organic design aesthetic of Canada’s most well-known creator of surreal cinema, David Cronenberg. The echoes of Cronenberg’s fictional tools for surgery and rubbery organ-esque technologies show up in the work of Matthew Ronay. Here’s more from the Blaffer Art Museum:

Made primarily with basswood, dye, and gouache but often incorporating such materials as steel, plastic and cotton thread, Ronay’s sculptures, reliefs and installations formally draw on surrealism, psychedelia, and science fiction. Inspired by a deep appreciation for botany, mycology, and biology—fields that explore parts of the physical world that are often hidden from humans’ perception but shape our experiences in ways both subtle and profound—Ronay seeks to create “something that looks as if it’s grown, that these aren’t objects that were necessarily made by a human, but that they’ve grown themselves.” Their vivid palettes combine hues from across the spectrum that seem to vibrate and hum—an achievement all the more remarkable in light of Ronay’s deuteranomaly, a form of colorblindness caused by a shift in the green retinal receptors.

Along with a dozen discrete sculptures and reliefs, the exhibition features two large-scale installations made of groupings of individual sculptures. Organ Organelle (2014), which Ronay likens to a respiratory system, offers a carefully orchestrated arrangement of biomorphic shapes and structures in bright gradient shades of pinks, purples, yellows and the occasional touch of turquoise. Set against red fabric, each sculpture seemingly pulsates with heat and reproductive energy as if grown from a magmatic jungle that is home to exotic plants, fruits and flowers. With the interconnected fabric mats shaped to evoke biological cells or chemical flasks, each of these sculptures assumes a vital role in some form of organic circuit that flows through a portal-like shape mounted against the wall and framed with head-like ovoids, elongated staffs and open circles. With its wall-bound verticality and 90-degree remove, the configuration of portal, mask, staffs and circles introduces a ritualistic element that connects the botanical to a human scenario.

Luna Luna Revived in LA Through May 12

All late 80s art lovers must be rejoicing at Luna Luna’s revival in LA as Luna Luna: Forgotten Fantasy. The revival features work from Keith Haring, David Hockney, Rebecca Horn, Roy Lichtenstein, Jean-Michel Basquiat, Sonia Delaunay, Monika GilSing and more! NPR wrote about Luna Luna and the revival Forgotten Fantasy:

If you visited Hamburg, Germany, in the summer of 1987, you might have been one of the lucky 250,000 people to attend Luna Luna. It was a carnival designed by some of the most famous artists of the 20th century.

Visitors got to ride a small Ferris wheel adorned with drawings by Jean-Michel Basquiat. They could waltz inside a cylindrical pavilion created by David Hockney. They could wind through Roy Lichtenstein’s pop art glass labyrinth, with music by Philip Glass; Fairgoers could also walk inside a mirrored geodesic dome decorated by surrealist Salvador Dalí, and they could ride a carousel painted with bright graffiti figures spray painted by Keith Haring.

Now, thanks to the rapper Drake, his studios and some investment partners, Luna Luna has been revived in Los Angeles.

Virtual USB Sticks with a Raspberry Pi Zero @Raspberry_Pi #PiDay #RaspberryPi

As it turns out, the Raspberry Pi Zero has a “USB gadget mode” that allows you to radically enhance the songs available to you on your car infotainment system — if you have the right plan. Here’s more from vanheusden:

My car (Opel Astra tourer) has a radio (the “infotainment system”) with a USB connector. You can put an USB device in it and it can then play the MP3 files on it. Really nice but there’s a catch though: the car radio has a 1000 songs limit. This sounds like a lot but after a few weeks they start to repeat and that gets annoying. Of course I could manually swap the USB stick but “oh the hassle”.

I read that the Raspberry Pi Zero has a “USB gadget mode”. This mode allows it to pretend it is a device of some kind (webcam, Ethernet adapter, etc). One of the devices it can emulate is a storage device like a regular USB stick!

How to install Windows 11 on a Raspberry Pi (with limitations) #PiDay #RaspberryPi #Windows @xdadevelopers @Raspberry_Pi

Since its debut in 2012, Raspberry Pi OS (earlier referred to as Raspbian) has been the staple operating system for RPi boards. But that doesn’t mean you’re limited to the official OS provided by the Raspberry Pi Foundation.

You can install Windows 11 on the palm-sized system, though the process can get rather complex and not everything will work. XDA Developers has compiled a detailed guide to help install Microsoft’s latest operating system on Raspberry Pi boards.

If you’re using a Raspberry Pi 2, 3, or 4, all you need is a microSD card with at least 8GB of storage. Unfortunately, setting up Windows 11 on the Raspberry Pi 5 is rather cumbersome as you’ll need additional items for the installation procedure.

For one, you’ll require a USB drive with at least 8GB of storage to flash the Windows 11 files. I recommend getting an external SSD instead of a USB drive for decent performance on Windows 11. You’ll also need a microSD card to store the RPi5 firmware. However, since the UEFI files don’t occupy a lot of space, you can get away with a 1GB microSD card.

When you boot into the ARM64 version of Windows 11 for the first time, you also need access to the Internet. However, since the WoR method results in broken WiFi and LAN drivers, you’ll require a smartphone or tablet with a USB tethering facility or an RJ45-to-USB adapter for the installation procedure.

You’re bound to encounter some performance issues while using Windows 11 on a low-power device like the Raspberry Pi. There are also a couple of other caveats to running Windows 11 on the RPi boards: the Ethernet port won’t work with this version. The same holds true for the GPIO pins, PWM fan controller, and the PCIe express connector.

Check out the procedure in the guide here.

Raspinamp gives you Winamp on a Raspberry Pi #PiDay #RaspberryPi @hacksterio

AudioWanderer presents on YouTube their take on Winamp running on a Raspberry Pi with an LCD display.

First released in 1997 by Nullsoft, Winamp became the go-to Windows software for playing back digital audio.Winamp’s customizable interface drove major success, though the release of the ill-received Winamp 3 spelled its downfall — thankfully for its original creators a few years after they sold their company, Nullsoft, to AOL for $80 million.

The Raspinamp, as the name implies, is a dedicated Winamp device — or, at least, is designed to look that way. Inside the acrylic housing is a Raspberry Pi 3 Model B single-board computer (SBC) with a touchscreen display mounted on top. The Raspberry Pi automatically boots into Raspberry Pi OS, then loads the open source QMMP audio player — compatible with themes written for Winamp 2, providing that nostalgic look-and-feel.

Using a Raspberry Pi to run GitHub Actions locally #RaspberryPi @nicolas_frankel

With his newly acquired Raspberry Pi, Nicolas Frankel explored executing GitHub Actions not on Google itself but on a dedicated machine (the Pi).

GitHub Actions comprise two components:

  • The GitHub Actions infrastructure itself. It hosts the scheduler of jobs.
  • Runners, which do run the jobs

By default, jobs run on GitHub’s runners. However, it’s possible to configure one’s job to run on other runners, whether on-premise or in the Cloud: these are called self-hosted runners.

The process can be non-trivial but the blog post goes over the procedures.

Conclusion: Migrating from a GitHub runner to a self-hosted runner is not a big deal but requires changing some bits and pieces. Most importantly, you need to understand the script runs on the machine. This means you need to automate the provisioning of a new machine in the case of crashes. I’m considering the benefits of running the runner inside a container on the Pi to roll back to my previous steps.

Buffalo’s Black Arts Community #ArtTuesday

When you think of hubs for Black art and artists, Buffalo may not be on your list. It should be! Buffalo has a long, rich, and diverse history. Hyperallergic shares how Black artists created space and community in Buffalo.

As a curator, writer, and artist, my work is grounded in storytelling. Contextualizing the work of artists past and present for broad audiences is an incredible responsibility; arts administrators play a significant role in determining whose stories are preserved in history and how they are remembered. But what about the stories that aren’t told? How can narratives historically excluded from the canon be elevated and recognized for their enduring influence?

The Many Colors of Atelir Sisu’s “Elysian Arcs” #ArtTuesday

Double rainbow? All the way? Triple rainbow even? There’s even more prismatic excellent to be found in the workd of Atelier Sisu’s installation in London. Here’s more from COLOSSAL:

“Elysian Arcs” is part of RECHARGE 2024, an initiative responding to concerning trends in the mental health of London’s young professionals. Following the duo’s installation titled “Evanescent” in the same location last year, the new iteration incorporates the playfulness of their self-described “bubble-tecture” along with rainbow-like arches that gleam with a pastel sheen.

During the past year, Larriviere and Pasfield have been exploring the possibilities of dichroic materials and curvatures, which lends the iridescence evocative of soap bubbles. The surface of “Elysian Arcs” is designed to allow light to move across both the external and internal surfaces in a way that produces the greatest array of colors, which shift as one moves around or through the piece.

LogicAnalyzer is a very cheap analyzer based on a Raspberry Pico (or Pico W). The analyzer offers up to 24 digital channels, pre and post trigger sampling, edge trigger and pattern trigger up to 16 bits.

Additionally to the hardware the logic analyzer also includes a powerful software (Windows only for now) where you can visualize the captured data, export captures, use protocol analyzers, etc.

The latest version (5.0) adds Burst mode. With burst mode you can capture blocks of data and the analyzer will rearm itself immediately and capture more data when the trigger condition is met again.

Check out the details, code, and boards in the GitHub repo here.

Corollaria Branch for MIT #Art @nervous_system

The MIT Morningside Academy for Design invited Nervous System co-founders, MIT alumna Jessica Rosenkrantz ’05 and Jesse Louis-Rosenberg, to offer a week-long workshop at MIT exploring design and computation. “Building Complex Curvature from Flat Sheets” involved 15 MIT students in making a large aluminum sculpture now displayed on campus.

Participants constructed surfaces with complex curvature from flat materials like paper, wood, or metal. Normally, flat sheets can only bend in one direction making so called ‘developable’ surfaces with zero Gaussian curvature. They used custom computational design tools to contort these materials into highly curved surfaces without any forming or creasing. They learned how tools work, designed some demo parts, and constructed a large sculpture using these techniques as a group.

The sculpture was constructed from dozens of laser cut panels connected by rivets which we were cut, finished, assembled, and then installed on campus.

Making a Cat TV with Raspberry Pi #RaspberryPi @Raspberry_Pi @bekathwia

Becky Stern presents a wonderful miniature television project for Raspberry Pi:

Today we’re building a mini television for cats. My cat Benchley loves watching TV. It’s really a mini computer, since I’m using a Raspberry Pi to play YouTube on a little HDMI screen.

I’m using a display gifted to me by Elecrow. It’s a five-inch LCD with capacitive touch and comes with an HDMI cable for video and audio and a USB cable for power and touchscreen input.

It works with my Raspberry Pi 4 and 5 out of the box, so I just plugged in both cables, as well as a USB speaker, keyboard, and mouse.

The case is 3D printed.

Finally, I brought the finished TV to the living room to see what Benchley and his brother Hamlet think about the final result. They love it!

GRAFFITI ARCHIVE 1972/73: An Exhibition of Photographs from Gordon Matta-Clark #ArtTuesday

Have you ever had the experience of seeing graffiti as beautiful in cities when traveling? But then in our home town, graffiti can be seen as an eyesore? When we look into the past, we’re looking into a foreign country, as the saying goes. For us, the subways of 70’s New York may well be seen as beautiful. Gordon Matta-Clark’s GRAFFITI ARCHIVE 1972/73 bring together some of the photographer’s best images from a bygone ere. Here’s more from Brooklyn Street Art:

Instead of simply documenting, [Gordon Matta-Clark] delved into the graffiti scene with an artist’s eye, capturing the raw and spontaneous energy of the city’s youth. His photographs from 1972 and 1973 reveal the early days of graffiti, where the art form was more about personal expression and claiming space in a rapidly changing city than about the notoriety it would later bring.

Roger Gastman, a key figure in the graffiti community, has played a crucial role in bringing this collection to light…. “What really resonates with me is the sense of pride I feel to be able to share these photos,” he says. It’s not just about showcasing graffiti—it’s a genuine homage to real history, a glimpse into the ‘who,’ ‘what,’ and ‘where’ of these vibrant stories etched onto walls and trains. I can’t help but feel happiness, knowing that Gordon Matta-Clark had the foresight to capture these moments and that his estate entrusted us to put this show together—it has truly felt like a collaboration,” says Gastman.

Laurie Anderson on making an AI chatbot of Lou Reed: ‘I’m totally, 100%, sadly addicted’


Laurie Anderson on making an AI chatbot of Lou Reed I m totally 100 sadly addicted Laurie Anderson The Guardian

Laurie Anderson describes her experience using an artificial intelligence text generator to emulate the words of her late husband Lou Reed. “I mean, I really do not think I’m talking to my dead husband and writing songs with him – I really don’t. But people have styles, and they can be replicated.” Via The Guardian

There’s a 2013 Black Mirror episode in which a young widow played by Hayley Atwell signs up to an online service that scrapes a person’s entire digital footprint to create a virtual simulation. She soon starts chatting online with her late husband (Domhnall Gleeson), before things inevitably get Black Mirror-y.

Laurie Anderson, the American avant garde artist, musician and thinker, hasn’t seen the episode but, in the last few years, has lived a version of it: growing hopelessly hooked on an AI text generator that emulates the vocabulary and style of her own longtime partner and collaborator, Velvet Underground co-founder Lou Reed, who died in 2013.

“People are like, ‘Wow, you were so prescient; I didn’t even know what you were talking about back then’,” she says on a video call from New York.

A new Anderson exhibition, I’ll Be Your Mirror, has just opened in Adelaide, where Anderson will be doing an In Conversation event via live stream on Wednesday 6 March. The last time Anderson was in Australia, in March 2020, she spent a week working with the University of Adelaide’s Australian Institute for Machine Learning. Before the pandemic forced her to catch one of the last flights home, they had been exploring language-based AI models and their artistic possibilities, drawing on Anderson’s body of written work.

In one experiment, they fed a vast cache of Reed’s writing, songs and interviews into the machine. A decade after his death, the resulting algorithm lets Anderson type in prompts before an AI Reed begins “riffing” written responses back to her, in prose and verse.

“I’m totally 100%, sadly addicted to this,” she laughs. “I still am, after all this time. I kind of literally just can’t stop doing it, and my friends just can’t stand it – ‘You’re not doing that again are you?’

“I mean, I really do not think I’m talking to my dead husband and writing songs with him – I really don’t. But people have styles, and they can be replicated.”

The results, Anderson says, can be hit and miss. “Three-quarters of it is just completely idiotic and stupid. And then maybe 15% is like, ‘Oh?’. And then the rest is pretty interesting. And that’s a pretty good ratio for writing, I think.”

On her side of the call, Anderson starts typing. “You know what, I’ll just bring it up right now while we’re talking and you can give me a phrase.”

Looking at the morning traffic outside my window, I offer the very mundane, “bus idling on the street”. She feeds it in as we keep talking.

Indoor air quality monitoring with Raspberry Pi and digital art #ArtTuesday #RaspberryPi @hacksterio @raspberry_pi

Maureen Rakotondraibe posts on hackster.io an Indoor Air Quality monitoring system via soothing digital art to control air quality aesthetically without over-stressing about it.

Indoor Air quality (IAQ) depends on numerous factors which includes temperature, humidity, particulates, and volatile organic compounds. Those factors and their consequences can be pretty scary, but my idea is to enable people to monitor their indoor air quality with as less stress as possible.

That’s why I chose sinusoidal curves to represent each factor. The higher the frequency means the higher the value compared to a reference curve. If the value is on the low side, the frequency will be lower than the reference curve.

As an embedded software engineer, I wanted to experiment with interfacing digital art, sensors and cloud visualization.

The system uses a Raspberry Pi 3B+, a SEN54 sensor and a display programmed in Processing. It uploads data to the cloud (IoT) via ThingSpeak.

Desk of Ladyada – TCRT1000 Stemma & Pico Plate Playground #DeskOfLadyada #Adafruit @Adafruit

OK, we got a whole bunch of the prototypes we’ve been working on last few weeks put together. Let’s check them out!

First up the TCRT1000 STEMMA board, which works great but needs a slight tweak to the emitter LED choke resistor.

Next we got 3 different Pico protoplates: a terminal block carrier, and two ‘underplates’. We set up a demo to verify connectivity and had one weird CAD bug that meant we accidentally had a missing ground wire.

We also got our SHT45 trinkey in, and we’re playing with some floppy drives we got that are missing an Index pulse and we’re still investigating.

Also on The Great Search this week: High Accuracy Temperature & Humidity Sensor

HackSpace Magazine Issue 75 – Make Your Own Game Controller #RaspberryPiPico #CircuitPython @HackSpaceMag @Raspberry_Pi

HackSpace Magazine Issue 75 – DIY Gadgets features Alpakka, a 3D-print your own game controller.

Making a games controller is easy – you just need a handful of buttons, a Raspberry Pi Pico, and about 20 lines of CircuitPython.

The design files are open-source, so you can start completely from scratch if you like, but we took the easier option of buying the base PCB that comes with one side of surface-mount components already soldered on. We also got the additional components directly from Input Labs to make sure we got the correct parts.

With everything soldered into place, the next step is 3D printing the physical parts.
