Smart home and IoT devices are nice and all, but controlling them always feels a bit clunky. It seems like it always comes down to trying a voice command and then, when that fails, opening an app on a smartphone and pushing a button. That’s why Unnecessary Inventions’ Matty Benedetto came up with this much […]
One of the things we love most about the Arduino community is the way knowledge flows freely – makers, engineers, and hobbyists sharing what they’ve learned so others can build on it. Case in point, the in-depth technical analyses coming from MyEmbeddedStuff, a blog dedicated to embedded systems written by an engineer with over seven […]
In a movie full of cool stuff, the most compelling fantasy in The Matrix is the ability to download and instantly learn skills. When skills take hundreds or even many thousands of hours to develop in the real world, that kind of on-demand skill access would be incredible. Designed by researchers at the University of […]
We’ve already seen lots of amazing projects based on Arduino UNO Q come up since its launch in early October – but we’re doubling down anyway! Today, we are launching a new Arduino UNO Q variant with 4GB of RAM and 32GB of eMMC storage, allowing all of you to dream bigger and go further, while […]
When we met Larry Bank at Maker Faire Rome 2025, we knew immediately that he was someone our community needed to hear from. Bank is what you might call a “perpetual optimist and inventor” – someone who not only sees problems but convinces people he can solve them, then does exactly that. His specialty? Code […]
That “digital rain” falling character animation from The Matrix is absolutely iconic. If you love the way it looks, you should build this desk clock by Bob Hammell that features the visualization. This smallish desk clock shows the time, with a digital rain effect from The Matrix overlaid on top. As the characters fall across […]
Bottle prepping machines make life just a little bit less hectic for overwhelmed parents, but they do still need to be started and that is easier said than done when you’ve got a wailing baby in your arms. That’s why Manivannan created this edge AI-powered system that automatically starts a bottle prepping machine when it […]
Every millennial knows the exhilarating feeling of going to the computer lab, booting up a Macintosh, and creating beautiful art in MacPaint. The nostalgia meter has broken its dial and is now spinning wildly. If you want to capture that nostalgia in a form suitable for home décor, you can build Mark Wilson’s fantastic LackPaint […]
Every year, some of YouTube’s most prolific makers get together to coordinate a Secret Santa exchange among themselves, then post videos of the results. The only rule is that they have to create the gifts. This year, Matty Benedetto (Unnecessary Inventions) got Austin Bradley in the exchange. For Bradley’s present, Benedetto constructed this set of […]
Brian got his hands on an old Lorenz 15 teletype machine, which was made in the 1950s. He also managed to snag an appropriate teletype modem. But the modem couldn’t seem to understand recorded teletype messages, so Brian used an Arduino Mega 2560 to “speak” teletype and get the Lorenz 15 printing. You can think […]
