This past weekend some Adafruit folks were lucky enough to attend a talk from Dr. Jane Rigby, who serves as Senior Project Scientist for the James Webb Space Telescope. Dr. Rigby’s address served as the keynote speech in the inaugural Tinsley Workshop series, hosted by the Yale Department of Astronomy.

Dr. Rigby went deep on some of the discoveries made by the JWST team and then took questions from the audience. One audience member asked whether or not the JWST is being used to search for alien life. Dr. Rigby pointed out that the JWST is not specifically designed to search for alien life. However, NASA is currently developing the tantalizingly named Habitable Worlds Observatory. Here’s more from NASA:

Currently referred to as the Habitable Worlds Observatory (HWO), this is a concept for a mission that would search for and characterize habitable planets beyond our solar system. Building upon studies conducted for two earlier mission concepts called the Large Ultraviolet Optical Infrared Surveyor (LUVOIR) and Habitable Exoplanets Observatory (HabEx), HWO would be designed specifically to identify potentially habitable planets around other stars, closely examining their atmospheres to determine if life could possibly exist.

The mission’s main objective would be to identify and directly image at least 25 potentially habitable worlds. It would then use spectroscopy to search for chemical “biosignatures” in these planets’ atmospheres, including gasses such as oxygen and methane which could serve as critical evidence for life. The observatory would introduce new capabilities to study the universe with unprecedented sensitivity and resolution, giving us important new insights into the evolution of cosmic structures, including how galaxies form and develop over time.

Hello Kitty was first drawn for Sanrio by Yuko Shimizu in 1974, followed by Setsuko Yonekubo then illustrator Yuko Yamaguchi who is responsible for the Hello Kitty we’re all familiar with today. Read more about Hello Kitty’s history from CNN:

Sales of Hello Kitty products flourished in Japan between the 1980s and mid-1990s. Much of the company’s earlier merchandise was aimed at young girls, including school supplies and personal care items like toothbrushes. But, even then, illustrator Yamaguchi knew the character would need to evolve and grow with her fans.

Public WiFi in London Gets Hacked

Adafruit is located in New York City where there is now public WiFi in the subway stations. The same is true across the pond in London, except their public WiFi was recently hacked. The hacker was able to change the login message to a message about terror attacks. An internal investigation found that the hack came from “inside”, a breached admin account. This is a good reminder to consider what data you send when connected to a public WiFi network. – BBC

image from doctr_sbaitso on reddit

doctr_sbaitso shared this awesome e-ink daily flipping Calvin and Hobbes frame on reddit!

A raspberry pi 4B, waveshare e-ink display and HAT driver. the python interface/drivers provided with the e-ink display write a bmp-format image out to the display, and it’s pretty ‘dumb’ (no scaling/interpolation) so the BMP needs to be exactly 800×480.

So I have some bash using imagemagick to handle the logic of incrementing a counter to pick the next daily strip (they’re sorted as entries in a textfile by date of print), figure out aspect ratio (daily strip or sunday strip), convert to a BMP, then resize it to 800×480 with the correct vertical or horizontal padding, and then write it out to the e-ink display; and of course, using cron to have it execute at 4am each morning.

hope that helps! pretty straightforward to do, and it’s a great project for anyone that enjoys tinkering!

Here is a straightforward list of products used and cost breakdown:

• raspberry pi 4B was $60
• waveshare 7.5″ e-ink display + hat driver was $66
• got a iUniker raspberry pi 4 case to house it all for $12
• got a short 90 degree usb-c to usb-c dongle for easier charging access, was $8
• photoframe from the local michael’s was $10 I think
• had a 32GB microsd card lying around, but thos can be had pretty cheap these days.

What do you think of when you think of a hacker? Today hackers have taken on international status as government-funded agents who can change the course of history. We might imagine a shadowy team in some droll office performing the 21st Century version of foreign interventions. That wasn’t always the case.

Forty years ago, hackers were thought of a nerdy solo acts. You might think about a particularly geeky Matthew Broderick accidentally pushing the world toward global thermonuclear war while trying to impress Ally Sheedy in WarGames. Hackers for quite some time were seen as basement dwelling, Doritos munching outsiders ready to break the law through nerdy means just to get a little status.

In 1995 that all changed. The movie Hackers dramatized in a very Hollywood sort of way what had already happened: rave culture, electronic and synth-based music, the early wild-west internet, conspiracy theories (back when they were fun), Blade Runner aesthetics, and a very cyberpunk view on politics had converged into a bleeding-edge cool. This vibe transformed the zeitgeist so much that by the turn of the century everybody was fluent in the visual language that first surfaced in the mainstream with Hackers.

Here at Adafruit, we love Hackers. One of the most fun Raspberry Pi projects we’ve seen comes from the ever-reliable HackersCurator. A re-creation of Nikon’s laptop, powered by Raspberry Pi. Here’s more:

We recreated a fully functioning reproduction of Lord Nikon’s laptop from the iconic cult classic film Hackers from 1995. Here is how we did it, and you can too! In Hackers, Lord Nikon A.K.A. Paul Cook, played by Laurence Mason sports an iconic laptop and startup sequence from the film. We wanted one that actually works. We captured the entire process on Twitch and have compiled the build into this video.

Check out the Feather RP2040 DVI Video Synth guide in the adafruit learn system!

In this project, you’ll use a Feather RP2040 with DVI Output to build a fun and funky video synth. The Feather runs Arduino code written with the Adafruit Fork of the PicoDVI library. All you’ll need is USB power and an HDMI monitor to start visually vibing with shapes, colors and static.

Check out the full guide! If you’re looking for even more video synth examples with the Feather RP2040 DVI, be sure to check out our friend TodBot’s video synth experiments. He’s done some great examples with lots of color and MIDI.

While I’m not motivated by counting down how many months I could have left, I certainly know a few folks who would proudly recreate and display rabbitcreek’s LifeTime tracker on Instructables:

The lifeTime provides you with an electronic version of this coda. It is an animated grid of tiny Neopixels stacked up into the months you will live over the course of 90 years. It requires that you input the owners birthday. On regular intervals the tablets open to reveal an animated display of how much time you have left. Otherwise it sleeps and provides you with background illumination that varies with the time of day and inspiration to think about life instead of death

The Adafruit Feather ecosystem is so rich with hardware diversity, we wanted to share them, one each day. Today is the Adafruit 0.56″ 4-Digit 7-Segment Display w/ FeatherWing – Blue!

One segment? No way dude! 7-Segments for life!

This is the Blue Adafruit 0.56″ 4-Digit 7-Segment Display w/ FeatherWing Combo Pack! We also have these combo packs in Green, Red, White, and Yellow!

7-Segment Matrices like these are ‘multiplexed’ – so to control all the seven-segment LEDs you need 14 pins. That’s a lot of pins, and there are driver chips like the MAX7219 that can control a matrix for you but there’s a lot of wiring to set up and they take up a ton of space. Here at Adafruit we feel your pain! After all, wouldn’t it be awesome if you could control a matrix without tons of wiring? That’s where these LED Matrix FeatherWings come in!

The 7-segment FeatherWing backpack makes it really easy to add a 4-digit numeric display with decimal points and even ‘second colon dots’ for making a clock.

The LEDs themselves do not connect to the Feather. Instead, a matrix driver chip (HT16K33) does the multiplexing for you. The Feather simply sends i2c commands to the chip to tell it what LEDs to light up and it is handled for you. This takes a lot of the work and pin-requirements off the Feather. Since it uses only I2C for control, it works with any Feather and can share the I2C pins for other sensors or displays.

The product kit comes with:

• A fully tested and assembled Adafruit 4-Digit 7-Segment LED Matrix Display FeatherWing
• Ultra-bright 4-digit 0.56″ tall blue seven-segment display
• Two 16-pin headers

"Nvidia dethroned Apple as the world's most valuable company on Friday..." reports Reuters, "powered by insatiable demand for its specialized artificial intelligence chips." Nvidia's stock market value briefly touched $3.53 trillion, slightly above Apple's $3.52 trillion, LSEG data showed... In June, Nvidia briefly became the world's most valuable company before it was overtaken by Microsoft and Apple. The tech trio's market capitalizations have been neck-and-neck for several months. [Friday] Microsoft's market value stood at $3.18 trillion, with its stock up 0.8%... Nvidia's shares hit a record high on Tuesday, building on a rally from last week when TSMC, the world's largest contract chipmaker, posted a forecast-beating 54% jump in quarterly profit driven by soaring demand for chips used in AI. The article points out that by the end of the day Friday, Nvidia's valuation had dropped to $3.47 trillion, while Apple had risen to $3.52 trillion...

"We passed Berkeley air — just outdoor air — into the material to see how it would perform," says U.C. Berkeley chemistry professor Omar Yaghi, "and it was beautiful. "It cleaned the air entirely of CO2," Yaghi says in an announcement from the university. "Everything." SFGate calls it "a discovery that could help potentially mitigate the effects of climate change..." Yaghi's lab has worked on carbon capture since the 1990s and began work on these crystalline structures in 2005. The innovative substance has lots of tiny holes, making it "great for storing gases or liquids, much like a sponge holds water," Yaghi said... While it could take one to two years for the powder to be usable in large-scale applications, Yaghi co-founded Atoco, an Irvine company, to commercialize his research and expand it beyond just carbon capture and storage. "Capturing carbon from the air just got easier," says the headline on the anouncement from the university, which explains why this technology is crucial: [T]oday's carbon capture technologies work well only for concentrated sources of carbon, such as power plant exhaust. The same methods cannot efficiently capture carbon dioxide from ambient air, where concentrations are hundreds of times lower than in flue gases. Yet direct air capture, or DAC, is being counted on to reverse the rise of CO2 levels, which have reached 426 parts per million, 50% higher than levels before the Industrial Revolution. Without it, according to the Intergovernmental Panel on Climate Change, we won't reach humanity's goal of limiting warming to 1.5 degreesC (2.7 degreesF) above preexisting global averages. A new type of absorbing material developed by chemists at the University of California, Berkeley, could help get the world to negative emissions... According to Yaghi, the new material could be substituted easily into carbon capture systems already deployed or being piloted to remove CO2 from refinery emissions and capture atmospheric CO2 for storage underground. UC Berkeley graduate student Zihui Zhou, the paper's first author, said that a mere 200 grams of the material, a bit less than half a pound, can take up as much CO2 in a year — 20 kilograms (44 pounds) — as a tree. Their research was published this week in the journal Nature. And it's also interesting that they're using AI, according to the university's announcement: Yaghi is optimistic that artificial intelligence can help speed up the design of even better COFs and MOFs for carbon capture or other purposes, specifically by identifying the chemical conditions required to synthesize their crystalline structures. He is scientific director of a research center at UC Berkeley, the Bakar Institute of Digital Materials for the Planet (BIDMaP), which employs AI to develop cost-efficient, easily deployable versions of MOFs and COFs to help limit and address the impacts of climate change. "We're very, very excited about blending AI with the chemistry that we've been doing," he said. Another potential use could be for harvesting water from desert air for drinking water, Yaghi told SFGate. But he seems very focused specifically on carbon capture. "Another thing is that we need a strong determination among officials and industries to make carbon capture a high priority. Things have to change, but I believe that direct carbon capture from air is very doable."
