Adafruit USB Host FeatherWing with MAX3421E

Lots of microcontrollers these days have USB ports on them, to program or debug, act like a keyboard or disk drive, or simply send data between a computer and your firmware. But did you know that you can also add a USB Host port? That means that your microcontroller project can have a keyboard or mouse or disk drive plugged into it – which opens up a huge ecosystem of common off-the-shelf devices that you can now integrate. The Adafruit USB Host FeatherWing makes it easy to add USB Host support, especially now that TinyUSB supports it in the Arduino library as a ‘native’ interface for host support.

Einstein continues to shine new light on the creation of matter. Fascinating development in physics based on the classics: E = mc^2

We discovered a simple regime where a near-critical plasma irradiated by a laser of experimentally available intensity can self-organize to produce positrons and accelerate them to ultrarelativistic energies.

Via Gizmodo:

“This research shows a potential way to explore the mysteries of the universe in a laboratory setting,” said Vyacheslav Lukin, a program director at the National Science Foundation, which supported the recent research. “The future possibilities at today’s and tomorrow’s high-power laser facilities just became even more intriguing.”

The experiment could provide a way to peer into the universe’s composition, by bringing some far-out physics much closer to home. But for that to happen, an experiment will actually need to be built.

I used Meshmixer by Autodesk to modify the Handle and elongate it to suite my set. It fits perfectly and works very well. I also used FreeCAD to export the STL file as Meshmixer does a fine job but the file was very large. FreeCAD made the STL smaller for some reason but took ages to import.

This project is also a good reminder that diffused leds tend to pop a little more. You can use a Black Diffusion Acrylic Panel or opt for a simple piece of tracing paper [like Miles did].

Via Hackster.io:

The device transitions between data types automatically (Ex. shows days and hours when days remain, but taking up the whole screen with the final seconds). While displaying information, a smooth RGB color cycle is displayed through the text color. When the event arrives, a personalized message and mixing RGB background is displayed.

When J.R.R. Tolkein created Middle Earth, he started with language. The rigor, originality, and poetry involved in creating a language may have contributed to the profound feeling of presence that the Lord of the Rings story brings for many people. But there are a lot of ways in to world building. Calendars, for instance. If you’re working with an alien world, and that world has two suns, or a large or small orbit, or an particularly elliptical path around its sun, then our Earth calendar just won’t work. In that case, your world building process may begin with making a calendar. Here’s more from Quark and Dagger:

First, it is possible to have a Tatooine type planet that orbits two suns. And it’s a really cool idea. The question is, how do you invent calendar system based on the two stars?

Remember to think logically, and try creating from a bottom-up perspective rather than top-down. That is to say, think about the people residing on the planet and where on the planet they reside. Will seasons affect them? Will the world only have a single season? How is the rotation around the two suns going to impact seasons? Are there even months at all or just a number of days in a revolution?

As he points out, for around the shop, you really don’t need more than 12′ a lot of the time, so why carry around 12 extra feet of tape? He recommends two tapes, a cheap, plastic-housed 12′ tape and a more expensive Stanley engineer’s tape measure.

Malicious hackers can spoof aircraft wreaking havoc on flight networks. I’m not sure how common ADS-B spoofing is but the repercussions could be devastation. Angelina Tsuboi created the Fly-Catcher for safer skies.

Hackers can easily spoof “ghost” aircraft into the sky. As a pilot and cybersecurity researcher, I developed a device called Fly Catcher to detect instances of aircraft spoofing on ADS-B 🛫. I also flew it on a plane over the coast of Los Angeles 🌴. Fly Catcher monitors the ADS-B 1090MHz frequency to detect spoofed aircraft by ground-based hackers using a custom neural network 📡. The device consists of a 1090MHz antenna, FlightAware SDR, and a Raspberry Pi, and scans nearby ADS-B messages and runs them through a neural network to detect fake aircraft transmitted by bad actors ⚡️.

I needed a mount for my GoPro camera that would attach to a standard pool pole. Upon searching, I discovered that such a mount was not available for purchase. Consequently, I designed and created my own mount. The homemade mount functions perfectly.

Wild world 2023 anton thomas art orig

Wild world is the creation of Anton Thomas. The map shows 1,642 animals in their native region. Armed with colored pencils and inspired by a childhood passion for geography Thomas created a cartographic masterpiece.

Nice write up from the New York Times:

So Mr. Thomas set himself guidelines. Animals should be native to their location and neither domesticated nor extinct. The names of places would, where possible, be the ones preferred by their inhabitants. Human-made borders do not feature. (In practice, this meant both names appear; the thylacine does not; and a Cantabrian brown bear supplanted the toro.)

Illustrated maps like Mr. Thomas’s are powerful in part because they mimic how the human brain perceives the world, said John Roman, an artist-cartographer in Boston and the author of “The Art of Illustrated Maps.”

Hard science fiction often focuses on technological developments. Books like that tend to ask for covers that depict space ships, space stations, advanced weapons of war, that sort o thing. But what about new wave science fiction focusing on abstract ideas like The Female Man, or books that use computing as a metaphor like Neuromancer, or that explore the intersection of power, politics, and religion like Dune? Those books demand something different, which is why many science fiction covers, especially the New Wave covers of the 60s and 70s, tend toward the abstract. Here are some of the best, from Artspace:

Vintage science fiction books have a cult following, with collectors willing to empty their wallets for limited editions of rare titles. Why? In part, because their covers are just so damn good. In an age when most people read on e-readers and screens, tangible book covers—especially ones drawn by hand—are becoming a thing of the past. Here, we absolutely judge these books by their covers, highlighting some of our favorites from the sci-fi genre. So many of them, created decades ago, feel so stylistically relevant today, as figuration, airbrush, and surrealism are back in vogue. Maybe these books really did forecast the future!

FREISA (Four-legged Robot Ensuring Intelligent Sprinkler Automation) uses a camera module to observe the surrounding environment and evaluate plants using AI. via Tom’s Hardware

Using a Raspberry Pi to make a robotic dog is nothing new but putting it to work is practically unheard of. The team behind this project created a robotic dog, known as FREISA, that uses AI to determine when a plant needs watering and helps the thirsty plant by activating its onboard sprinkler system. This project was created by a team that goes by B-AROL-O with members Davide Macario, Andrea Podo, Gianluca Teti, Gianpaolo Macario, Orso Eric, and Pietro d’Agostino.

Bookworm is the newest version of Raspberry Pi OS. Since releasing a couple months ago the team has been working on tweaking and refining. An update announced on Wednesday brings bug fixes and a long wished for dark mode.

This update includes improved support for encrypted connections in WayVNC; the latest version of Thonny; Mathematica and Scratch 3 working on Raspberry Pi 5; and a bunch of other small bug fixes and tweaks. But we thought we’d give you a little pre-Christmas bonus in this release too…

Creating a dark theme can be relatively easy, or really hard, depending on how the colours have been defined in your original theme. If all your colours are defined as variables, it is relatively easy — but if all your colours are hard-coded values, then it is rather more time-consuming. And of course, in PiXflat, as in Adwaita before it, the colours were all hard-coded! So the first job was to go through 4500 lines of CSS and find all the hard-coded colours, replacing them with variables, and then setting those variables to the original hard-coded values so I didn’t break the original light theme.

Super cute 3D printed light up Christmas tree project. Shared by maketvee.

Watch the whole build above and get full details on Instructables, Printables and hackaday.io

This is a 3D-printed Christmas tree with embedded addressable LEDs inside. So it is possible to program the LEDs for nice light effects and using the 3D printed structure as a diffusor.

The tree is separated in 4 stages and a base element (the tree trunk) to make it easier to assemble and embed the LEDs during the prints. So in total 5 elements have to be printed.

LEDs are part of the print, they are not removable afterwards. Please ensure that everything works fine before embedding them into the print.
