Just wanted to pass along some praise for your site.
Yes, you guys have a lot of cool electronics stuff — but I wanted to
highlight your blazingly fast product database search. I’ve never seen
anything like it on-line! It’s so responsive it feels like it’s
searching a local database. Kudos!

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

It’s a big day for important numbers. From Gizmodo:

Move aside 282,589,933-1, there’s a new prime juggernaut in town. That’s right: A researcher and former NVIDIA employee has found 2136,279,841-1, the largest known prime number, which clears the former record-holder by over 16 million digits.

Durant used a supercomputer comprised of thousands of GPUs in 17 different countries to find the number, first with an NVIDIA A100 in Ireland, and later confirmed by an NVIDIA H100 in Texas. For his efforts, Durant will receive $3,000 from GIMPS.

Rides a theme parks are great. They’re better when they’re themed. Disney maks most of its money from its theme parks — such is the power of immersive storytelling. What about science fiction themed rides and experiences? Here’s a list of vintage and ongoing science fiction themed from Starloggers:

Mission: Space (Epcot): According to some astronauts, this ride does a great job of recreating a rocket launch. Centrifugal forces do a number on riders enclosed in narrow, claustrophobic stations that simulate a spaceship being launched and escaping Earth’s gravity.  Riders play specific parts as team members on their way to Mars. Mission: Space is so rough that a milder version of the ride had to be introduced.

Professor Gillian Forrester of the University of Sussex recruited more than 1600 visitors to the Science Museum to research human biases and preferences for handedness. Find out why most people write with their right hand and more.

Many creatures across the animal kingdom prefer to use one side of the body over another, just as humans do: 90 per cent of people using their right hands as their ‘write hands.’

Every person should have a 50-50 chance of being left or right biased so why do we prefer to be lopsided in the way that we behave, and our brains work?

It could take months to years for astronauts to journey to Mars and back, but what if there was a way to make the trip shorter? NASA and Defense Advanced Research Projects Agency are figuring out how to use nuclear engines for future Mars missions. via Space

This relatively long transit time is a result of the use of traditional chemical rocket fuel. An alternative technology to the chemically propelled rockets the agency develops now is called nuclear thermal propulsion, which uses nuclear fission and could one day power a rocket that makes the trip in just half the time.

An all in one bedside table build by SR on Hackster.io. It features an aroma diffuser, a sunrise lamp, charging pads and more. Made with a few bits of Adafruit as well!

The Customizable Electronic Module includes power sockets, USB and Type-C ports, wireless charging pads, and a smart aroma diffuser and many more. It offers convenient power access, flexible charging, and calming aromatherapy. This module seamlessly integrates into your space, enhancing comfort and functionality with modern design.

What makes Kequel Unique ?
Many smart furniture brands on the market today offer innovative designs and features. However, they often fall short in providing the flexibility that allows users to customize their experience fully. These brands typically offer a fixed set of electronic components, leaving users with limited options for personalization.

Imagine if you lived on a pleasant block in a nice neighborhood for your entire life. You know your neighbors, you chat with the mail carrier, and you check in on the retiree who lives a couple doors down in a house painted a once-bright orange. But you’ve never been to any of the adjacent blocks. And what lies beyond that, well, you’ve certainly never set foot there. When will you visit these nearby blocks? When will you have a better sense of your neighborhood? We often have the idea that we know a great deal about our solar system, but the truth is, we know very little.

That’s where the Europa Clipper and European Space Agency’s Jupiter Icy Moons Explorer  come in. Here’s more from Centauri Dreams:

Europa may itself offer another boost if Europa Clipper’s science return is anything like what it promises to be. Closing to 15 kilometers from the surface and making 49 passes over the icy ocean world, the spacecraft may give us further evidence that outer system moons can be venues for life. We also have the European Space Agency’s Jupiter Icy Moons Explorer (JUICE), which will study Europa, Callisto and, in a spectacular move, end up orbiting Ganymede for extended close-up observations.

JUICE gets to Jupiter in July of 2031, while Europa Clipper starts its flybys in the same year, though arriving in 2030. As a measure of how tricky it can be to get to these destinations, both craft make flybys of other worlds, returning in fact to the Earth for some of these. Europa Clipper’s journey will be marked by gravity assists from Mars in February of 2025 and Earth in December 2026. JUICE has already performed one Earth/Moon flyby and will make a flyby of Venus (August, 2025) followed by two Earth flybys (September 2026 and January 2029). A long and winding road indeed!

Trinket / Gemma Space Invader Pendant Learn guide!

Pac Man is my best friend.

Okay, not really. But as a child of the 80’s, video arcade games were a huge cultural phenomenon of my formative years.

Tiny affordable microcontrollers are a cultural phenomenon of today’s generation.

This project bridges the generations to create an animated LED necklace or charm that you can customize to create a retro-style personal “totem video game creature.” It’s a small project, good for electronics novices and group workshops. And you’ll have something eye-catching to wear and show off afterward.

Check out the tutorial here!

Rachel Freire recently shared this banger of a process writeup over on Instructables, detailing the collaboration between Melissa Coleman, Rachel Freire, Rebecca Odedra and Joachim Rotteveel to make a sick wearable for Imogen Heap:

However. I recently came across these pictures while reviewing our documentation… And the drama of it all, the zoomed out theatricality [in the cover image]… is DIY-able AF!

And unless you have an insane controller you want to sync to do very refined, specific things, you can absolutely make this for 10-20£/$/€ [maybe less]

Learn how to use the Adafruit Joy Bonnet for Raspberry Pi!

Pocket-sized fun is the name of this game, with the Joy Bonnet – our most fun Bonnet ever (no we didn’t even think that was possible, either!) This Bonnet fits perfectly on top of your Raspberry Pi Zero (any kind) and gives you adorable hand-held arcade controls. Once you install our script onto your Pi, the controls will act like a keyboard, for easy use with any emulator or media player.

Personally, we found this Bonnet to work best with RetroPie/EmulationStation. On a Pi Zero we could emulate NES and MAME game (our favorites!) but other emulators that don’t require more than 1GHz speeds will work OK too, e.g. a N64 emulator won’t work, it needs way more power!
