Rare Works from First African-American Photo Studios #ArtTuesday

Smithsonian has acquired the works.

via ArtNews

In an acquisition that has the potential to significantly expand the way the story of photography in the United States is told, the Smithsonian American Art Museum in Washington, D.C. has added 286 works from Larry J. West’s photo collection to its holdings. Dating between the 1840s and around 1925, the works acquired include pictures by some of the most prominent early Black photographers in the U.S., among them James P. Ball, Glenalvin Goodridge, and Augustus Washington.

Hung Liu’s Portraits of Promised Lands at National Portrait Gallery August 27 – May 30 #ArtTuesday

If you’re anywhere near the National Portrait Gallery we hope you get a chance to visit Hung Liu: Portraits of Promised Lands! From National Portrait Gallery:

Often sourcing her subjects from photographs, Liu elevated overlooked individuals by amplifying the stories of those who have historically been invisible or unheard. Having lived through war, political revolution, exile, and displacement, she offered a complex picture of an Asian Pacific American experience. Her portraits speak powerfully to those seeking a better life, in the United States and elsewhere.

Tina M. Campt’s A Black Gaze: Artists Changing How We See

In A Black Gaze: Artists Changing How We See Tina M. Campt examines Black contemporary artists and the dismantling of the white gaze. From Bookshop.org:

Campt shows that this new way of seeing shifts viewers from the passive optics of looking at to the active struggle of looking with, through, and alongside the suffering–and joy–of Black life in the present. The artists whose work Campt explores challenge the fundamental disparity that defines the dominant viewing practice: the notion that Blackness is the elsewhere (or nowhere) of whiteness. These artists create images that flow, that resuscitate and revalue the historical and contemporary archive of Black life in radical ways. Writing with rigor and passion, Campt describes the creativity, ingenuity, cunning, and courage that is the modus operandi of a Black gaze.

The Illusory Sculptures of Li Hongbo #ArtTuesday

What do you have when you cross a Rodin with a slinky? You have the work do Li Hongbo. That doesn’t really do the astonishing sculpted paper sculptures justice. Here’s more from JUXTAPOZ:

Li Hongbo’s paper sculptures can accommodate all sorts of shapes. They can bend. They can stretch like accordions. Their flexibility is key to challenging and engaging the viewer. “When you change the external form of an object, people will reconsider the material itself and the creative motivation behind it.” To reconsider, to muse over the materials and the artist’s motives is part of the aesthetic experience proposed to the viewer. Uncertainty and ambiguity become a playground where information can be shared, where emotions can be felt.

The Mechanical Art of Lukas Milanak #ArtTuesday

Lukas Milanak make art out of unlikely machines. Here’s more from Art the Science:

Perhaps my work most consistently aligns with the evolution of science itself. All knowledge is built on the wisdom of what came before. Influences of biology, geology, and physics become more apparent in the work as my awareness of the world around me grows. I also find a strong connection to the spirit of 18th-19th century alchemy. It was the wild west for experimentalists, and groundbreaking discoveries – and follies – were happening faster than ever before. I study and adapt glass forms and techniques from the age of alchemy in the hopes of stirring the same feeling of scientific urgency in my work.

Meet Atlasminx, the 4863 Piece #3DPrinted Puzzle

Thoroughly enjoyed watching this video from corenpuzzle on YouTube, but ooof, we’re still trying to wrap our brains around trying to solve this best. via Gizmodo:

The design of the puzzle was inspired by Matt’s yottaminx and Oskar’s 17×17. The biggest change I made to the floating anchor mechanism was to change the direction of the “hooks” each part has. That allowed for the parts to be printed in an orientation that minimized the need for support material in FDM printing. I also added a kind of foot to 25% of the center pieces that prevents them from twisting in place and also helps with sorting.

Gemäldegalerie Alte Meister Releases Image of Completed Vermeer Restoration

Art restoration is one of these processes that might as well be controlled, patient magic and we are totally here for it. Especially when it means the world gets to see a restored Vermeer Cupid. From Gemäldegalerie Alte Meister via The Art Newspaper:

Since 2017, this early masterpiece by Vermeer has been undergoing restoration following careful scientific investigation. Recent research has shown that the extensive area of overpainting in the background was not done by Vermeer himself. Removal of this overpainting has revealed a depiction of a standing Cupid (god of love) as a “painting within the painting” on the rear wall of the room, thus radically changing the overall appearance of the work. The spectacular result of the restoration will give viewers a different perspective on the painting.

Pi Data Clusters as Space Heaters? #piday #raspberrypi @Raspberry_Pi

Thermify HeatHub wants to utilize excess heat from data processors for home heat. This could cut back on heating needs and not waste energy for cooling. Its an interesting idea for sure.

VIa Current:

The HeatHub includes 450 Raspberry Pi processors, which collectively sit in a box the size of a combi boiler. The heat generated by undertaking cloud computing tasks contracted to the company will be used to heat a water tank over the course of about two hours.

“In the early days, we heated a radiator, and a small bucket of water,” explained Felgate. “So that was really the gestation of the company, and we haven’t moved very far from it.”

Building a fun front panel with Raspberry Pi Zero #PiDay #RaspberryPi #AdafruitForums @Raspberry_Pi @kf_rookie

Adafruit Forums user brer_rabbit (Twitter @kf_rookie) posts a really fun panel design:

I’m not sure what I’m making, but it’ll have a ton of LEDs, switches, knobs, etc. etc. with a Pi Zero under the hood. At least it’ll look cool!

You can see all the easter eggs in the control names!!

Here are the electronics: I spy an Adafruit Pi T-Cobbler, Pi Zero with headers, Yellow LEDs, and 4 digit displays!

New Life for Proto-PDA #piday #raspberrypi @Raspberry_Pi

Before smartphones there were PDAs or Personal Digital Assistants. One of the first incarnations was the Psion Organiser. Updated by A Menadue on YouTube. Via Hackaday:

Like many of the early attempts at putting a computer in your pocket, the Psion II had removable modules, which were dubbed “Datapaks”. The earliest versions of the Datapaks were little more than an EPROM chip on a small PCB, and the technical limitations of the day plus the quirky way of addressing the memory made it possible for [Amen] to mimic a Datapak using a modern microcontroller.

The Simpsons TV Made IRL with Raspberry Pi @Raspberry_Pi #PiDay #RaspberryPi

Here’s a cute little working version of the Simpsons TV. Here’s more from Kotaku:

On Reddit, buba447 promises a how-to guide but provided this explanation for how it works in the meantime, explaining that inside was a Raspberry Pi Zero with a 32 GB and card. The Pi was connected to a 640×480 display and powered by a USB cable. The episodes were all compressed specifically for the screen. They were then loaded onto the SD card and then begin playing episodes at random. The speaker is a cheap, one-incher that buba447 salvaged from a dead piece of old hardware. The whole thing is impressive. Well done!

One of the most significant advantages of Plex is that it can transcode video files to your devices. Transcoding allows even a device like the Raspberry Pi to play a vast range of video files.

The Brassberry #piday #raspberrypi @Raspberry_Pi

via von Heddernheim on instructables

Some weeks ago I found an old and empty watch case on a scrap yard. The brass case weighs more than 5 kg.
Battery acid had nibbled (eaten away) at the case and it was green in many parts (acid & copper rust). The remaining parts were nearly black. After I had cleaned the case, I thought, this becomes a Multimedia centre for videos, pictures and music and I built a Raspberry Pi in this case.

Recycle Your old Raspberry Pi Boards with OKdo @Raspberry_Pi #PiDay #RaspberryPi

Your old Raspberry Pi boards now have a home. OKDo can get your old versions or no longer used Raspberry Pis to folks who’ll make good use of them. Here’s more from the Raspberry Pi Blog:

Raspberry Pi boards are manufactured at the Sony Technology Centre in Wales, and that’s where OKdo returns all the hardware you donate. When it gets there, it’ll be tested, reconditioned, and repackaged, ready to be sold to its new home. OKdo will be offering the refurbished boards at a lower price than new boards, and they all come with a twelve-month warranty.

Raspberry Pi Temperature and CO2 Monitor @Raspberry_Pi #PiDay #RaspberryPi

OT3PjaQh1r blob

Great looking project from agxies up on Hackster.io.

This project is ideal if you already have a Raspberry Pi running 24/7, e.g., as web server, printer server, pi-hole etc. Then you can easily add extra functionality like air monitoring, which will be achieved by realizing this project. At the end, you will have a small status screen displaying temperature, humidity, TVOC and CO2 values.

Make Your Own Pet Food Monitor #piday #raspberrypi @Raspberry_Pi

Learn how to make your own pet food monitor to make you that much more prepared for your office return from Raspberry Pi Projects:

The targeted outcome for this project is to build a system that can monitor how much food is
inside a pet food bowl in real-time. The system will be interfaced with a camera that will be
aimed at the bowl at all times, so that it can take a picture of it and use it for analysis. After the
picture is taken, the system will run an image processing algorithm using OpenCV to determine

Castles of Tuscany Insert/Organizer #3DPrinting #3DThursday

Patella shared this project on Thingiverse!

Basic insert. Should be lots of space if any expansions come out — but might need some redesign if so. It passes the shake test, but if you’re going to store it flat, you can avoid printing out some of the spacer pieces.

As shown in the photos, you will need to print the following. (Again, you can avoid printing most of the spacers if you’re storing it flat.)

Water heater drip pan hose adapter #3DThursday #3DPrinting

Shared by TinyTraders on Thingiverse:

The drip pan in around my water heater in the basement had a fitting for a large PVC pipe coming out, but I needed to run a hose to my sump pump. I have no idea how much of a leak this will support, so I may be sorry about that but I designed an adapter so that I could use a garden hose.

There is a parametric bolt module in Blender that can be used to size bolts and nuts. You may want to make the adapter a bit thinner to fit your gasket-mine was a bit tight

NES Max Dpad #3DThursday #3DPrinting

It would be pretty hard to come by an original Dpad. If you need a replacement check out this print from Riverbottom on Thingiverse:

The Cycloid ruins a perfectly good controller, so I designed an insert to fit into the cycloid and replace the slider, turning it into a D-pad.
There are 2 versions the shallow (which is closer to flat, similar to a Nintendo D-pad) and a Deep version closer to a Genesis or Xbox one D pad. I find the deep version works a little better.

split 89-key mechanical keyboard with QMK Config #3DPrinting #3DThursday

jurassic73 shared this project on Thingiverse!

This keyboard build was inspired by the Microsoft Ergonomic 4000 keyboard I used for roughly 12 years or so. I broke my left wrist twice over the years so an ergo keyboard is a must for me to type comfortably all day long else my left wrist starts to burn after a few hours of typing on a regular keyboard. This is a real bummer since there are so many amazing keyboards out there. I could not find a split TKL like this layout so I designed one. This has a 6° tent and a 3° incline. I designed this to sit as low as possible with these angles on a table. One key switch is actually in a recess in the baseplate with a few mm of material below it.

5 wide washers for holding Ring.

4xM4 screws for attaching the whole thing to wall. Use the length you prefer for your use. I used 70mm ones.

2x 2x10mm screws for sg90 mounting (optional if wanted a secure attachment to base)

1x sg90 with continuous/360 rotation.

Star Trek TNG VISOR Kit #3DThursday #3DPrinting

Really nice looking visor straight out of the next generation from UnimatrixRed on Thingiverse:

I wanted to make a TNG VISOR prop with an easy-to-print one-piece grill instead of installing a lot of rods. This has a flexible grill that prints flat and fits nicely in grooves to secure it. This makes painting easy but also lets you print in color if you want. I used silk PLA for the metal parts which came out shiny but paint is probably better looking.

There are 2 versions of the grill: grill 1 is modeled after the jagged ‘banana clip’ style in season 1, grill 2 is the full tooth style most commonly seen. To make sure it fits, the rounder side of the grill faces the top. Use color swap function to use black and gold for the grills with screens.

I designed this dolly fro my camera using #fusion360, hoping to get some cool shots fro improving my Youtube video quality. The deisgned is super easy to print and required materials are pretty cheap, making the project aviable for everyone. Due to the smooth bearings and rubber O-rings the dolly is pretty fluid, with large wheels and a low center of gravity we have planty of stability, making this project great fro heavy cameras like a DSLR. The filament used for this project is PLA black and PLA Silk Red, both from TIANSE, an incredible brand wich provides high quality filaments.
