Azuma Makoto’s Ephemeral of Frozen Flowers Will Melt Away #ArtTuesday

The sign that once read “HOLLYWOODLAND” now solemnly proclaims to everyone toiling away in to bring us entertainment that the land has been lost and only the empire of light remains. But this past week, not even the famed HOLLYWOOD sign in the Santa Monica Mountains could escape the snow that swept through the higher altitudes of the usually Sunny west coast. The frozen peaks above the San Fernando Valley and Malibu would look just right in the work of Azuma Makoto. Here’s more from COLOSSAL:

On a frozen lake in the Notsuke Peninsula, a tendril of land that juts out from Hokkaido’s east coast, acclaimed floral artist Azuma Makoto has constructed the third botanical sculpture in an ongoing series called Frozen Flowers. The first edition was composed in this same location in 2019 and again in 2021, and every year, the conditions have been a little bit different. The artist is interested in how variables like temperature, wind, or snowfall can alter the surrounding environment and make every version unique.

An important facet of Makoto’s practice is working alongside and adapting to nature and striking a collaborative balance so that he’s neither trying to control it nor controlled by it. Arranged on a scaffold and surrounded by a field of snow, bunches of flowers and foliage in a range of colors and textures are doused with water before they solidify into thousands of icicles. The artist and a team of assistants worked through the night, waiting until temperatures were at their lowest so that the ice would form quickly. The following morning, the sun revealed the finished composition, and by design, ultimately melted it.

Chocolate Velociraptor

Is it me or does this guy kind of make Wonka look like an amateur??

Amazing chocolate creation (video) from Amaury Guichon on YouTube.

This chocolate creation is the largest and most challenging piece I have ever done. It weighs 550lbs (250kg) and has an imposing height of 8ft (2,44m). It took me a total of 10 days from start to finish. I love the way it turned out!
There is truly no limit to what can be done with chocolate!

The new Raspberry Pi Pico development software installer for Windows #RaspberryPiPico #RaspberryPi @Raspberry_Pi

Today Raspberry Pi introduced a simple solution to install everything you need to develop for Raspberry Pi Pico, and for other RP2040-based boards, using C or C++ on Windows.

Up until now, information has primarily been for Linux, and specifically on a Raspberry Pi running Linux.

When we launched Raspberry Pi Pico and its SDK, our assumption was that people would be happy with a Linux-based toolchain. However, we also documented how to get the toolchain up and working on both Apple’s macOS and Microsoft Windows for folks that wanted to use those platforms. Unfortunately, while installing the SDK on macOS isn’t too different from doing so under Linux, and works almost out of the box, installing things on Windows is much more difficult; it’s just a very different environment.

Installing the toolchain is now as simple as downloading and running, the Pico Installer. There is an option to also install the Pico examples. The installer sets up a Visual Studio Code environment for development.

Everything also works with the new Raspberry Pi Pico Debug Probe announced Monday.

BAM Presents: “Art is Energy”: Lorraine Hansberry, World Builder

If you’re unfamiliar with Lorraine Hansberry, “Art is Energy”: Lorraine Hansberry, World Builder is a great start. Soyica Diggs Colbert curated this amazing exhibit at BAM

“Art is Energy”: Lorraine Hansberry, World Builder presents, some for the first time, photographs, letters, recordings, and published and unpublished writings by Lorraine Hansberry. The exhibition mixes mediums to evocatively capture Hansberry’s multiplicity—the world that she inhabited and the one she created in The Sign in Sidney Brustein’s Window. The exhibition was curated by Soyica Diggs Colbert and made possible through generous partnerships with Joi Gresham and the Lorraine Hansberry Literary Trust; the Schomburg Center for Research in Black Culture, a research library of the New York Public Library (NYPL); and Alison Saar and The Lorraine Hansberry Initiative.

Photographs of Black History and Culture Available From Getty’s Archive #ArtTuesday

There was that time when some folks thought “Via Getty” was the name of a photographer. That’s easily understood, really, given how many online photos can have that watermark set at a jaunty angle across the image. Getty Images is a supplier of stock images, video and music, with an enormous library library of over 477 million assets. And now Getty Images had made over 30,000 photographs of Black history and culture available online. Here’s more from COLOSSAL:

From a black-and-white portrait of a reclined James Baldwin to a candid shot of a father and daughter on a Harlem park bench, a new archive from Getty grants open access to thousands of images devoted to Black history and culture. The massive collection—which was developed with historians and educators Dr. Deborah Willis, Jina DuVernay, Dr. Tukufu Zuberi, Dr. Mark Sealy MBE, and Renée Mussai—comprises 30,000 photographs taken in the U.S. and U.K. that are available for free non-commercial, educational use. Applications for access are open now.

Organized by decade from the 1800s to the 2020s, the Black History & Culture Collection offers a broad, varied look at the people, events, and undeniably influential movements that continue to shape life today. The collection is further searchable by type and subject matter, which encompasses everything from art and entertainment to politics and sports. You can find a curated selection of images from the multimedia platform Black Archives, which partnered with Getty to shine light on specific moments from the collection.

Pixel Wrangler: Send HDMI video to whatever #ArtTuesday #Video #FPGA @qrs

Have you ever wanted to take HDMI video and output it as art or display it on devices that are not normally HDMI compatible? If so, Pixel Wrangler from Trammell Hudson is for you.

The Pixel Wrangler is a tool for converting HDMI video into anything else. It uses an ice40up5k FPGA to decode the video stream and stores a section of it in the block RAM, which can then be clocked out of the 16 GPIO pins in any other format required.

Since the FPGA has total flexibility in how it drives the output pins it is easily adaptable to different protocols. Some examples that are possible:

Classic CRT monitors like B&W Mac or Hercules monitors

LED matrices

Flip dots

LED strips (ws2812 or other protocols)

Lots of servos for “wooden mirrors”

Check out some of the uses on Mastodon and see more about the project on GitHub.

Engineer Pete Warden gave the exhibit an enthusiastic endorsement on his blog a few weeks back.

When I think of a museum with “craft” in its name, I usually imagine an institution focused on the past. San Francisco’s Museum of Craft and Design is different. Their mission is to “bring you the work of the hand, mind and heart“, and Bull.Miletic’s Proxistant Vision exhibition is a wonderful example of how their open definition of craft helps them find and promote startling new kinds of art.

How to 3D PRINT A GUITAR via @prusa3d #3DPrinting

Prusa Research shared on YouTube:

How to 3D PRINT A GUITAR – the challenges, how it sounds, and how much it costs

3D printing an electric guitar has always been a dream of mine, but it seemed like such a daunting task. Would the body snap under the tension of the strings? Would it bend over time? Would I need to use special active pickups? Would the plastic body produce an awful sound compared to traditional hardwood? There were so many questions and surprisingly few answers to be found online.

The new Raspberry Pi Debug Probe: a plug-and-play Arm debug kit #RaspberryPi #RaspberryPiPico #Arm @Raspberry_Pi

Today, Raspberry Pi launched the Raspberry Pi Debug Probe, a complete debug hardware solution for Arm-based microcontrollers, powered by RP2040, and priced at just $12.

The Raspberry Pi Debug Probe provides:

A USB to Serial Wire Debug (SWD) bridge
A generic USB serial adapter
Cables to connect to a host computer, and to the debug target

What is a debug probe?

All modern Arm-based microcontrollers, including RP2040, implement Arm’s CoreSight debug architecture. Each processor core, like the Cortex-M0+ used in RP2040, provides an Access Port (AP) which can be used to single step, set breakpoints, observe the values of processor registers, and access memory and peripherals via the processor’s bus interface.

While it has been designed with Raspberry Pi Pico, and other RP2040-based targets, in mind, the Raspberry Pi Debug Probe can be used to debug any Arm-based microcontroller that provides an SWD port with 3V3 I/O.

For users who do not require debug functionality, the Raspberry Pi Debug Probe’s low price makes it a cost-effective alternative to other USB serial adapters, such as the once-ubiquitous FTDI cable.

The U.S.P.S. will launch a new series of stamps celebrating “The Art of the Skateboard”

Skateboarding stamps v2 jpg

There’s a new stamp in town and frankly, it has me feeling rather old!

Rolling Stone recently reported that the USPS will debut a new stamp series that honors skateboard art.

The Alaska-based artist Crystal Worl reflects her Tlingit/Athabascan heritage in the blue-and-indigo design, according to the U.S.P.S. William James Taylor, Jr., who lives in Virginia, came up with a red-and-orange pattern. The Colombian-born Federico “MasPaz” Frum, who grew up in Washington, D.C., where he still paints murals came up with a jaguar-like design. And Arizona’s Di’Orr Greenwood paid tribute to her Navajo culture with art that evokes eagle feathers and rising and setting suns. Art director Antonio Alcalá designed the stamps using photos of skate decks.

The USPS will hold a dedication ceremony next month in Phoenix, AZ. Event details and RSVP information can be found here.

DIY Raspberry Pi Smart Phone @Raspberry_Pi #PiDay #RaspberryPi

The answer is yes, you can make a functional DIY smart phone powered by a Raspberry Pi. Here’s more from Hackaday:

[asherdundas], the phone’s creator, actually found a prior build based around the Raspberry Pi before starting this one. The problem was that it was built nearly a decade ago, and hadn’t been updated since. This build brings some modernization to the antiquated Pi phone, and starts with a 3D printed case. It also houses a touchscreen and a GSM antenna to connect to the cell network. With some other odds and ends, like a speaker and microphone, plus a battery and the software to tie it all together, a modern functional Raspberry Pi phone was created, with some extra details available on the project page.

The phone has the expected features — including calling, texting, and even a camera. A small WiFi USB dongle allows it to connect to the Internet too, allowing it to do all of the internet browsing a modern smartphone might want to do. The only thing that it might be pretty difficult to do is install Android apps, and although there are ways to get Android apps working in Linux, it’s not always strictly necessary to have this functionality.

See project!

Raspberry Pi Pico generating composite PAL video #PiDay #RaspberryPiPico @Raspberry_Pi

GitHub user guruthree is trying to get the Raspberry Pi RP2040 chip’s PIO to generate a colour PAL composite video signal, using only a resistor ladder digital-to-analogue converter (DAC).

WARNING: THERE IS A CHANCE THIS SOFTWARE MAY DAMAGE YOUR PICO. I TAKE NO RESPONSIBILITY. I’m running the RP2040 at 312 MHz. This is a 141% overclock (or 241% of stock) with a 1.2 VREG voltage. The clock divider on the PIO is about 9. It is a lot of data to process in not a very long period of time (64 microseconds). I believe I have partially broken at least one RP2040 working on this.

As for my specific hardware, I’ve used both a Pimoroni Tiny2040 and a regular Pico. I’ve built two different simple (read: less precise) resistor DACs…my newer DAC (has) 33k, 18k, 10k, 5.6k, 2.2k, 1k, 560 and 270 Ω resistors.

I have a suspicion that when overclocked not all RP2040 chips end up at exactly the same frequencies, and not all TVs lock on to the PAL colour carrier as easily, so if you are unable to see a colour image you may need to play with the CLOCK_SPEED and CLOCK_DIV settings.

Due to the technical limitations of RAM and DAC timings, it’s been an ongoing effort to work out video resolutions. The best I’ve been able to get so far is a “super high” resolution of 220×110 at roughly a 7 bit colour depth. The major challenge for higher resolutions at this point is RAM, and I think a more standard 320×200 resolution is otherwise possible.

There are numerous links to principles and similar projects.
