AI Agent VideoCAD Learns to Use CAD to Create 3D Objects From Sketches

image via MIT

MIT engineers have developed a new AI model that can use CAD software to create a 3D version of a 2D sketch.

With VideoCAD, the team is building toward an AI-enabled “CAD co-pilot.” They envision that such a tool could not only create 3D versions of a design, but also work with a human user to suggest next steps, or automatically carry out build sequences that would otherwise be tedious and time-consuming to manually click through.

A Christmasy Fantasy & Sci-Fi Book List

Back in 2021, Julia Kitvaria Sarene shared their SFF Christmas book list on Fantasy Faction.

In the Northern Hemisphere the weather is getting cold, the trees are bare, snow is in the air (or at least I wish it was!) and it is slowly coming—Christmas is just around the corner!

As a full on Christmas addict, I especially love fantasy and sci-fi stories that pick up on the theme. Over the years I accumulated more titles than I thought I would find, and today I’ll share my list of holidays SFF with you! Obviously, this is not an exhaustive list, just those I read already and plan to read!

New Years Eve Project! 3D Printed Ball Drop #CircuitPython

New Years Even Ball Drop on Adafruit Learn System

Code and CAD on GitHub

Using Circuit Python in this project was an excellent decision as it allowed us to make adjustments quickly so we could fine tune the ball drop with synchronized audio.

The Adafruit Feather ecosystem is heavy in this project. The Tripler FeatherWing manages boards nicely and you get extra pins and power rails. Easy to swap in and out different boards.

I was able to 3D print big dual extruded domes, thanks to our new Ultimaker S5. This cuts down the print time from 21 hours to just 8hrs for a single dome by using a bigger nozzle and layerheight.

2020 aluminum extrusion works wells as a framing for builds because its strong and lightweight. With 3D printed roller wheels and ball bearings it can be made into a slider with a linear railing system.

Arduino TFT Display for Motorcycle Riding Directions and Notes

Follow your own path while cycling with this cool project from clif_barnes shared shared on instructables. Happy Riding!

The intent of this project is to be an alternative to GPS directions when my wife and I are riding our Can Am Rykers (look up Can Am Ryker…they’re a blast!). At times, a GPS device can send you on a different path then desired when a destination/location is keyed in. Sometimes, I want to display my own directions and have quick & safe access to it while in motion. I use the GPS Garmin live map display in conjunction with the TFT Display / Directions. The “gotcha” is having a laptop/tablet with Arduino IDE close by to create and transfer directions…unless one plans ahead at home [which is what I do]. The Base Camp Application for the Garmin, which I find somewhat user-unfriendly (to be fair…it’s probably just me), also drove the need for this project.

Qualcomm rewrote Arduino’s TOS, and the community is not taking it well @TechSpot

Alfonso Maruccia over on TechSpot weighs in on the Terms of Service changes Arduino has made after being acquired by Qualcomm.

When Qualcomm announced its acquisition of Arduino in October, the move was met with lukewarm enthusiasm. Since then, the UK chip designer has implemented significant changes to Arduino’s terms of service, prompting concerns within the community that the moves could effectively signal the end of the platform’s open-source ethos.

Key updates reportedly include a perpetual license on any code or board designs uploaded by users, surveillance-style monitoring of AI features, and a prohibition on research into potential patent infringements. Additionally, Arduino can now retain account usernames indefinitely after account termination, while all user data is integrated into Qualcomm’s global data ecosystem.

“Several sections effectively reshape Arduino from an open community platform into a tightly controlled corporate service with deep data extraction built in,” Adafruit Industries said.

Arduino stated that the revised documents are intended to improve clarity, ensure regulatory compliance, and support innovation. They are also designed to guide the platform in navigating emerging IT trends, including AI and new commercial opportunities.

The Invention of Ambient Music #MusicMonday

In a recent episode of the Apple TV series Pluribus, the main character finds herself on a silent elevator. She wonders aloud whatever happened to muzak? Is is true that today’s elevators are silent? If so, whatever did happen to muzak? muzak, for all its absurd emptiness, did one great thing: muzak occasioned the creation of ambient music. A new video on Brian Eno and his legendary album Music for Airports from Pearl Acoustics tells the tale:

When the composer and music producer Brian Eno had to suffer intolerable ‘muzak’ in an airport departure lounge, while waiting for his flight home back in the 1970’s, he concluded that there must be something better to fill the void. The result was the creation of a totally new genre of music which he called ‘Ambient’. Designed to be played in any circumstance and not requiring the intellectual participation of the listener, unless desired, this album ‘Ambient 1 – Music for Airports, was the first LP in the new genre and set a ball rolling that is very much alive, 47 years later. In this video I explore the life of Brian Eno and this fascinating composition and recording.

Here’s more from Pearl Acoustics?

Harnessing Excretion for Science

Nature shares how researchers harness pee and poo for science.

The implications of research into human waste span several scientific disciplines. Amid a global fertilizer shortage, some scientists (and farmers) are looking to urine as fertilizer, owing to its nitrogen content. A study in Nature Water3, published earlier this year by a group of researchers at Stanford University, California, created a prototype system that extracts nutrients from urine. The team estimates that its design could generate up to US$4.13 per kilogram of nitrogen recovered. And research published in 20204 shows that urine-based fertilizer might also help to conserve other resources, reducing greenhouse-gas emissions and water use.

Tracking Individual Monarch Butterflies

Monarch butterflies roosting in a tree image via Mike Budd/USFWS

 

Monarch butterflies weigh less than a gram, putting any tracking device on one would overburden the insect. But BlūMorpho (“solar-powered transmitter operating at 2.4 GHz (Bluetooth frequency), allowing detection by both dedicated wildlife receivers and everyday smartphones.”) changes that. Project Monarch is a collaborative effort of researchers and enthusiast working on some of the most detailed flight mapping ever captured.

Via Xerces Society for Invertebrate Conservation

Everything changed in November 2024 when a butterfly named Lionel, equipped with a new additional bit of programming code, dubbed Blū+, was released in Cape May Point. By tapping into crowd-sourced location networks, Lionel provided the first high-resolution track of monarch migration ever recorded, with hundreds of detections to St. Augustine, Florida.

“Lionel’s track was a pivotal moment for us,” said Dr. Sean Burcher, Senior R&D Scientist at CTT and Science Director at CMPASC. “With hundreds of millions of devices all acting as passive receivers we were able to watch the fine-scale movements of Lionel in near-real-time.”

Tiny Space Invaders on the Raspberry Pi Pico 2

photo via tinajackson on Reddit

tinajackson on Reddit shared this cool miniature Space Invaders powered by a Pi Pico 2 and displayed on a tiny SSD1306 OLED. Check out the full post and source code on GitHub.

I’ve been playing with a Raspberry Pi Pico 2 and had a spare SSD1306 OLED display plus an HW-040 rotary encoder lying around.

The idea was to make a minimal Space Invaders clone that fits on a 128×64 screen.

Before writing any code, I sketched the layout in a small browser-based graphics editor I made (kind of a Figma for embedded screens).

It took maybe 10 minutes to draw the ship, invaders, and place text elements.

Then I copied the generated Micropython code straight into Codex AI agent, and within about half an hour the game was done.

The hardest part was still the wiring and boilerplate – getting the encoder and OLED to talk nicely to the Pico. Also having the UI draft ready saved a lot of back-and-forth.
Explaining layout details to Copilot/Codex without a draft with all images would’ve been painful.

UK Couple Heat Home with Raspberry Pi Data Cluster #piday #raspberrypi

Terrence and Lesley Bridges’ garden shed holds more than tools. As part of an experimental program the couple have a mini data-center to help heat their home. The HeatHub system runs off electricity paid for by the end user and the Bridges get to recycle the excess heat generated. Win-win?

Via BBC:

The HeatHub was developed by Thermify and is part of UK Power Networks’ SHIELD project, which aims to come up with innovative ways for low-income households to transition to net zero.

Thermify co-founder and CEO Travis Theune says the Bridges’ HeatHub will eventually be part of a “remote and distributed” data centre, involving many units processing data for customers.
While not designed for the heavy processing needed for artificial intelligence, Mr Theune says the system could run things like apps or analyse large volumes of data.

Tuning Out Excessive Motion Noise When Controlling Robotic Devices #WearableWednesday

Photos by David Baillot/UC San Diego Jacobs School of Engineering

Engineers at the University of California San Diego have developed a wearable system that enables people to control machines using everyday gestures even when on the move. You can read more about their research published in Nature Sensors.

The technology could enable patients in rehabilitation or individuals with limited mobility, for example, to use natural gestures to control robotic aids without relying on fine motor skills. Industrial workers and first responders could potentially use the technology for hands-free control of tools and robots in high-motion or hazardous environments. It could even enable divers and remote operators to command underwater robots despite turbulent conditions. In consumer devices, the system could make gesture-based controls more reliable in everyday settings.

A Kinetic Star System Sculpture on a Coffee Table! #ArtTuesday

Just in case you need a little dread in your life, here is a kinetic sculpture that recreates a degrading star system. Not that anything like that would ever happen to our solar system, at least not before our sun gives up out of sheer exhaustion. That said, a model of a system degrading may be a strange sort of comfort. If that’s the case for you, here’s the project from The 5439 Workshop via lackaday:

This is a coffee table, not a particularly practical one, but one that I wanted to make. It has a mechanical orrery (star system) with both tilting orbits and an exploding star. It is built from cherry wood and aluminium, I have never used this many tools for a single project, it’s everything from woodworking, metal working / welding to 3d print, electronics and some coding (used simplefoc). I’m trying to combine my builds with storytelling, I enjoyed getting into vfx a bit too much.

The Good TRON #SciFiSunday

Maybe you never saw the 1982 movie TRON. Maybe you’d only ever seen the remake or maybe not even that because you heard that except for the Daft Punk sound track it wasn’t that good. But maybe you’ve stood inside the legendary TRON arcade game The Discs of TRON, the black light transforming you into a digital creature. Maybe you loved the sound of identity discs banking off glowing blue walls and maybe you felt your stomach fall as your avatar tumbled from the last reamining circular platform, derezzing into the microprocessor void, another victim fo the Master Control Program. Maybe when you finally saw the 1982 masterpiece its unique blend of computer generated images, blacklight animation, genre-defining production design, and live-action convincing abdolutely blew your mind. And maybe you knew in your meatworld bones that if you could ever venture inside TRON you’d absolutely rule at those lightcycles. Here’s an exploration of how the unique 1982 marvel was made, from The Guardian:

Tron’s distinctive glowing circuitry was achieved through a technique called backlight animation, which involves making a negative of each frame and hand-painting the glowing areas. There were 75,000 frames to do; more than half a million pieces of artwork. Nobody knew how it would come together until the last minute, and reshoots were virtually impossible.

Tron’s CGI elements were an entirely separate process. Computer graphics had been used in movies before Tron, but only in brief snippets. In 1973’s Westworld there is a clip of a robot’s-eye pixellated view, for example. Star Wars and Alien both feature 3D wireframe graphics projected on screens. Only a few companies could produce such images, each of which had their own room-sized computer and their own custom-built software. The process was still cumbersome. “We had to figure out how to position and render objects 24 times to make one second of perceived movement on the screen,” says Bill Kroyer, Tron’s head of computer animation. Tron’s animators had to map out the CGI scenes on graph paper, then calculate the coordinates and angles for each element in each frame. Computer engineers would then input all the numbers manually. And there was no way of seeing the results until the images were printed on to 35mm film and projected in the theatre.

Read the Time or Play Snake with SerpenTime

Arnov Sharma shared this delightful clock that doubles as a console for Snake on Hackster.io:

Serpentime is a compact, dual-mode creation that blends the utility of a digital clock with the charm of a retro Snake game console. With a single button press, it shifts from timekeeper to game machine, powered by an Xbox controller for a surprisingly immersive experience.

In clock mode, it fetches time, date, and weekday data via NTP and displays it in crisp white panels with bold black cut-out text.

Switch to game mode, and you’re greeted by a smooth Snake game driven by the controller’s left joystick, complete with gradient snake segments, pulsing food, and a live score overlay.

3D-Printed Digital Camera

via Dycus on Reddit

Reddit user Dycus shared how they brought this camera to life. It even includes an unconfirmed version of one of our OLED breakout boards. Tom’s Hardware shared the details.

A 3D printing enthusiast has made a cute, functional digital camera using an optical sensor salvaged from a discarded mouse PCB. This is an admirable recycling-inspired maker project to see completed, and you can witness it in action in the embedded Reddit post below. However, don’t set your recycling old rodents into digital cameras’ hopes too high, as the results are definitely lo-fi.

The First Stock Ticker Debuted 158 Years Ago Today

On November 15, 1867 the first stock ticker was debuted. Invented by Edward Calahan, the ticker revolutionized the stock market. History explains.

The last mechanical stock ticker debuted in 1960 and was eventually replaced by computerized tickers with electronic displays. A ticker shows a stock’s symbol, how many shares have traded that day and the price per share. It also tells how much the price has changed from the previous day’s closing price and whether it’s an up or down change. A common misconception is that there is one ticker used by everyone. In fact, private data companies run a variety of tickers; each provides information about a select mix of stocks.

From the Adafruit Learning System: Trinket / Gemma Mini-Theremin Music Maker

In the Adafruit Arduino Lesson 10, Pseudo-Theramin, an Arduino Uno is combined with a light-sensitive cadmium sulfide (CdS) photocell to make a light responsive music machine. This project allows you do do the same with an Adafruit Trinket or Gemma mini-microcontroller. This project costs less and works in smaller circuits or wearable projects.

Changes in light intensity on the photocell will change the pitch of a note on the piezo speaker as you wave your hand in front of the cell. While not a true theramin (which uses changes in a circuit’s reactance), this project is much simpler to build.

Check out the guide from Anne Barela.

Tasks an ESP32 can handle better than a Raspberry Pi

The Raspberry Pi is phenomenal board. The SBC is a go-to for multitasking and processing. Sometimes, though, you want precision for a single task that an ESP32 offers. Samir Makwana outlines five use cases where the ESP32 might outshine a Raspberry Pi. Via XDA:

The ESP32 is designed to complement the Raspberry Pi, not replace it. That said, deploying several ESP32 boards will still be economical when you need multiple devices compared to a host of Pi models. Also, you won’t need to purchase microSD cards for it. While Pi shines as a full-fledged single-board computer, it’s best harnessed for complex projects.

However, when you need a board to communicate directly with hardware and deliver real-time performance, the ESP32 is the solution. It is best suited for tackling efficient, time-sensitive, and precise controls for IoT builds and automations.
