Farmers can use the same “big data” tools that are integrated into other industries. Things like drones that communicate with satellites to collect data while soaring over a field. The internet of things era means just about anything in our lives can be linked to a WiFi connection and the same applies for farming. For example, Wifi-enabled moisture sensors can help farmers conserve water by only watering parts of the field that need it most. Cow tags can be linked to GPS or even “Fitbit-like” devices to track their vitals remotely. Most machines can be programmed to use machine-learning; for example, fertilizer application equipment can be trained to “see” a field and only spray plants that need a boost, saving farmers product and money.

As a nightly cat snuggler, yea, checks out! Nice to hear it empirically demonstrated by Oregon State researchers:
In their study, the OSU researchers had cats participate in a “secure base test,” similar to a test that has been given to infants and dogs to study their attachment behaviors. During this test, the cat spends two minutes in a new room with their caregiver, followed by a two-minute alone phase, and then a two-minute reunion phase.

MIT engineers have created a blackest black coating from carbon nanotubes that is reportedly 10 times darker than any material created before, including Vantablack.
The coating, which is made from vertically aligned carbon nanotubes (CNT) grown on chlorine-etched aluminium foil, can absorb 99.995 percent of visible light.
“Our material is 10 times blacker than anything that’s ever been reported,” said Brian Wardle, professor of aeronautics and astronautics at MIT.
If you want to keep the firmware on your ESP32 WiFi co-processor up-to-date, you'll need to update the firmware on the ESP32.
You're going to to turn your board into a USB-to-Serial converter to flash new firmware to your ESP32 - no extra hardware required!
This process is mostly setup and should take from 10 to 20 minutes.
Using an ESP32 as a WiFi co-processor is a way to connect your CircuitPython and Arduino projects to the internet. Having WiFi managed by a separate chip means your code is simpler, you don't have to cache socket data, or compile in & debug an SSL library.
Adafruit ships a variety of products which use the ESP32 as a WiFi co-processor with a variant of the Arduino nina-fw core. This firmware is programmed to the ESP32 at the Adafruit factory. If you wish to update to a newer version of nina-fw, you'll need to program it to the ESP32.
If you already have a project which uses a popular microcontroller (like the ATMega328 or ATSAMD51), you can easily add WiFi by using an externally connected ESP32 module.
Don't want to add extra hardware to your project? Consider grabbing a board which has an ESP32 WiFi co-processor built-in.

Kidding. It’s HALLOWEEN! Time for candy and spooky monster dress-up! Maybe you’re looking for ideas for your MONSTER M4SK board. Here’s something I quickly scared up to rattle some ideas loose…
This isn’t meant as an A-to-Z build guide…I wouldn’t expect everyone would want to make this exact thing. But the process of incorporating MONSTER M4SK may be insightful…
I wanted to go a little beyond the basic “stick the MONSTER M4SK on something” idea and show a couple of its more unusual features in action:
I also had some helpful tips to pass along on selecting a mask, dealing with electronics in costumes, and so forth. So even if you’re not making this exact thing, you may want to skim through the guide before starting your own MONSTER M4SK project, whatever it may be.

Adafruit interviews Tim Clarke Master Toy Designer “King of Gross”, Co-Creator of Boglins and Sectaurs. Sculptor of Dark Crystal mystics! Tim’s site is here – www.totims.com
“For over 30 years Tim has been Inventing, Designing and Sculpting some of the most unusual toys to ever be marketed in the US and abroad. Once known as the “King of Gross” after co-creating in the 80’s Sectaurs (Coleco) and Boglins (Mattel). Tim now launches his new line of horribleness the “TOTIMS”
I love creating my own mythology. The world is filled with modern day mythological creatures you can find them in every nook and cranny of your bedroom closet.
Tim Started his career designing and building puppets for the Muppets. Most notable were the Mystics and the Slaves that he sculpted and designed for the movie the Dark Crystal guided by the incredible drawings of Brian Froud. He also worked on puppets for Sesame Street , Muppet Show and Fraggle Rock for which he created Traveling Matt. After Dark Crystal was launched he garnered his first toy sculpting gig with Hasbro creating the Garthim, Mystics and Lanstrider toys.
He has also created toys for Melissa and Doug toys, EK Success, Hasbro, Mattel, Coleco, Kenner, Ideal Lossirs, to mention just a few.”
The Story of the 1987 Boglins Toyline – A Mini Documentary – YouTube.
We’ll also showed some more Boglins that have been “upgraded” with Adafruit electronics 
“Boglins were a series of toy puppets distributed by Mattel. They were created by Tim Clarke, Maureen Trotto, and Larry Mass, and licensed by Seven Towns. The original run of Boglins was released in 1987, coinciding with a “creatures” craze that included Ghoulies, Critters, and Gremlins. Boglins were goblin-themed hand puppets made of flexible rubber and could be manipulated to represent speech and facial expressions. Several series of large and small Boglins were released until 1994, with additional aquatic, Halloween, and baby themed Boglins released later into the line. Small solid ‘Mini-Boglins’ were also produced, akin to the M.U.S.C.L.E. figures also from the 1980s.”

The “house music” sound also evolved rapidly with the advancement of technology. DJs took house music to the next level by incorporating synthesizers, samplers, effects processors, and drum machines which introduced the consistent 4/4 tempo. These early innovators also started to loop basslines, add percussion layers, mix in effects, add vocals, and apply other remixing techniques. This new and innovative electronic sound immediately captured the hearts of clubgoers.
Wonderful story from Atlas Obscura.
In 1728, the young Jane Colden moved with her family to a plot of land in the Hudson Valley that, according to her father, was populated less by people and more by “wolves, bears, and other wild animals.” Much of colonial New York was forested back then, and the overgrown landscape would become Colden’s office as she worked as a prolific amateur botanist, drawing and describing 400 species of plants that grew in her (relatively sprawling) backyard.
Though she spent her entire life isolated in this rural area, her work was recognized internationally, particularly by naturalists in the United Kingdom such as John Ellis, Peter Collinson, and the aptly named Alexander Garden. Today, Jane Colden is commonly acknowledged as the first female botanist in what would become the United States, noted for her forward-thinking adoption of the relatively new Linnaean taxonomy.
From MusicTech:
The concept of physical modelling had been around since the beginning of the 70s, but a practical application of the concept had to wait until the end of the decade, when it was discovered almost by accident.
This guide will show you how to use an FT232H to connect to I2C and SPI sensors and breakouts from your desktop PC running Windows, Mac OSX, or Linux. The FT232H also allows for general purpose digital input and output (GPIO) for things like buttons and LEDs.
The cool part about this is that you can then use any of the CircuitPython Libraries that have been written for the numerous sensors and breakouts.
As you are going through this guide, keep in mind the difference between CircuitPython and CircuitPython Libraries:
There are various hardware combinations that allow for running CircuitPython and CircuitPython Libraries. In this guide we will not be using the actual CircuitPython firmware. But we will be using CircuitPython Libraries. To explain this further, let's go over the main hardware platforms and explain where the FT232H fits in to all this.
This is the most straight forward setup.
If you are using a microcontroller that can run CircuitPython, then you will most likely have the low level hardware interfaces needed to access the many sensors and other breakout boards - I2C, SPI, and GPIO. Even better, there is most likely a CircuitPython library written for the sensor.
In this case, you simply install CircuitPython, add the libraries, and then follow whatever guide goes along with your sensor.
This setup requires a special shim library called Blinka.
Single Board Computers (SBC), like the Raspberry Pi and Beagle, also typically have I2C, SPI, and GPIO interfaces available. These boards are also powerful enough to run complete operating systems, like Linux. They can't run CircuitPython directly, but generally don't need to. They can run the much larger Python implementations, like CPython. To allow use of SBCs running Python to use CircuitPython libraries to access sensors over I2C/SPI/GPIO, the Blinka library was created.
In this case, you pip install Blinka, pip install libraries, and then follow whatever guide goes along with your sensor.
This is where the FT232H comes in. Here's why.
So what about your super powerful desktop or laptop PC? They can most definitely run Python. But can they also use CircuitPython libraries and talk to I2C/SPI sensors? Can they blink LEDs? Read buttons? Generally, no. As powerful as your Windows, Mac, or Linux PC is, it most likely does not have those low level hardware interfaces. Look on the back of your computer. Do you see an I2C port? A SPI port? A cluster of pins labeled GPIO? Nope.
So what can we do? Well, look again at the back of your PC. See any USB ports? Most likely there are several. Heck, there are probably even several USB ports on the front of your PC! Can we use USB? Yes, thanks to a specialized USB bridge chip made by FTDI - the FT232H.
This will allow us to do something like this:
With FT232H support added to Blinka, we can follow a similar approach as with the SBCs. The FT232H attached to the USB port acts as our surrogate set of low level hardware interfaces.
Neat! Let's see how we can get this all setup and working.
Check out these mind blowing skate tricks! Jenkemmag shared this video on Youtube!
When we first compared Matt Tomasello to some kind of drugged up version of Rodney Mullen, it was meant to be somewhat a joke, since bath salts probably don’t improve your skating (except in rare instances).
But now, a year and two videos later, we still haven’t found a better way to describe Matt’s skating, but maybe it’s because there isn’t a better description.
Matt’s skating, with all his folding and unfolding board contraptions, no handed pogos, and sideways grinds, slides, and flips, feels like just that. You even have to rewind it or watch it in slo-mo just to comprehend most of his clips.
So for the final(?) installment of Matt’s trilogy, we’re sticking with comparing him to Rodney on bath salts. Enjoy it if you can, or click back to a simpler time when Todd Falcon was the most technically advanced skater out there.

Their study builds on a well-known insight from Edward Lorenz of MITwho, in 1961, wished to repeat one of his weather simulations using a simple computer model but got quite different results because of a tiny rounding error in the numbers he fed into the computer.
…
The richness of the real world is entrained with irrational numbers which cannot be represented on any digital computer (‘and will not be representable on a quantum computer either’, he adds). ‘For Lorenz, it was a very small change in the last few decimal places in the numbers used to start a simulation that caused his diverging results,’ he says. ‘What neither he nor others realised, and is highlighted in our new work, is that any such finite (rational) initial condition describes a behaviour which may be statistically highly unrepresentative’.
Look at that landing! From BostonDynamics on YouTube:
First, an optimization algorithm transforms high-level descriptions of each maneuver into dynamically-feasible reference motions. Then Atlas tracks the motions using a model predictive controller that smoothly blends from one maneuver to the next.
Adorable research is showing that kittens bond the same way human infants do. Structured off of a 1960’s experiment on babies, the team found very similar attachment patterns to their caregivers.
Via Nova:
“A lot of people have these stereotypes about cats, that they’re aloof or solitary,” says Kristyn Vitale, an animal psychologist at Oregon State University. “But they [also] use their owners as a source of security when they’re stressed out.”
Vitale’s newest paper, published today in the journal Current Biology, may suggest exactly that. Using a version of the Strange Situation adapted for domesticated felines and their human companions, she and her colleagues have found that the majority of cats tested appear to establish a secure bond with their caretakers—similar to the way that babies (and dogs) do, they argue.

We recently wrote about RunwayML as a machine learning platform for creators. Recently, RunwayML started collecting some impressive projects built with their tool. The posts for these ‘experiments’ vary from blog style write-ups with videos (like the trippy paint your face away video) to full interactive applications that you can test out in the browser.
The image above shows an example from one of the interactive ‘experiments’ called ‘Generative Engine‘. Generative engine is billed as a ‘storytelling machine that automatically generates images as you write’. This multi-sensory experience is reminiscent of live painting at concerts with it’s mix of modalities (and it’s pretty fun). The Generative Engine utilized the AttnGAN model which does ‘Fine-Grained Text to Image Generation with Attentional Generative Adversarial Networks’. If you’d like to learn more more about the AttnGAN model checkout the paper or try implementing it on RunwayML or with the code on Github.

The vehicle is driven by two NEMA 17 stepper motors. I decided for steppers instead of DC motors because they don’t need any regulators and allow to position the vehicle with an accuracy better than one centimeter per meter. An other advantage is their high torque especially on low rotation speeds. Disadvantage are the higher weight and higher power consumption. But in my opinion, the advantages make up these weak points.

Cool project and write-up from instructables user TexasMouse.
With the new Raspbery Pi 4 (RPi4) just released, I decided to make myself a home-use firewall. After stumbling around on the Internet, I found a great article on the subject by Guillaume Kaddouch (https://ift.tt/2LXnGmN). The article is amazing, and you should read it before going forward–it will make the process described here easier. The thing is, that article was written in 2012 and is based on the ArchLinux distro. Nothing against ArchLinux, but I wanted to make this using the more common Raspbian build.
