This Arduino failsafe protects an amazing backyard observatory

from Arduino Blog [alt+shift+b] in technology

Nothing quite compares to the feeling of looking up at the cosmos on a dark night, and even an affordable telescope can enhance that experience. But if you’re willing to spend the time and money, you can take things much further. That’s what Redditor CosmicRuin did when they built an amazing backyard observatory. And they […] The post This Arduino failsafe protects an amazing backyard observatory appeared first on Arduino Blog.

This mouse droid knows how to party

Not a lot of thought went into the “mouse droid” in the first Star Wars movie. It was just a bit of cute world-building, created by putting a box on an RC car. But it became a fan favorite and that in-universe model, the MSE-6, appears throughout subsequent movies, TV shows, and video games. All […] The post This mouse droid knows how to party appeared first on Arduino Blog.

From voice command to robotic arm: how agentic AI on the edge is changing the factory floor

For years, bringing real intelligence to industrial automation meant expensive infrastructure, proprietary systems, and steep learning curves. That’s changing – fast. Foundation models powerful enough to run at the edge are turning natural language into machine control, and the factory floor is starting to look a lot more like a conversation. AI as the new […] The post From voice command to robotic arm: how agentic AI on the edge is changing the factory floor appeared first on Arduino Blog.

Build your own handheld retro console with the Arduino® UNO™ Q board

Arduino® Project Hub has featured a lot of DIY handheld consoles on this blog over the years. Most of them are impressive, and most of them require at least some custom hardware – a purpose-designed PCB, a specialized connector, a part you can only get from one supplier. They’re great projects, but they can feel […] The post Build your own handheld retro console with the Arduino® UNO™ Q board appeared first on Arduino Blog.

How to achieve cost-effective predictive maintenance with the Arduino® UNO™ Q board

Most machines warn you before they fail. A motor begins to vibrate differently. A pump slowly drifts out of balance. A bearing develops a new mechanical signature. A cooling fan starts producing frequencies that were not present during normal operation. These changes can appear well before a complete breakdown. The challenge is detecting them early, […] The post How to achieve cost-effective predictive maintenance with the Arduino® UNO™ Q board appeared first on Arduino Blog.

The Pinecone DAISY-1 is a fantasy 8-bit computer that exists in reality

There was a time when computers were exciting and fun. Now most of them feel like commodity appliances — no more interesting than a washing machine or a toaster. Joe longed for the good ol’ days of 8-bit personal computers, so he used a trio of Arduino development boards to design his own “fantasy computer.” […] The post The Pinecone DAISY-1 is a fantasy 8-bit computer that exists in reality appeared first on Arduino Blog.

Radxa's Q8B has 2x the performance and expansion of the Pi 5

There was a time I'd look at a board like the Radxa Dragon Q8B (at left, above) and be like, "there's no way I'd spend $209 on an SBC with 8 gigs of RAM". But we're in 2026, and seeing the 8 gig Raspberry Pi 5 going for almost the same amount, I figured I'd give it a shot. On paper, the Q8B beats the Pi 5 in pretty much every way. A lot of that is thanks to this Snapdragon 8cx Gen 3 chip, which is the same chip I tested on Microsoft's Windows Dev Kit 2023.

The Sting

The Sting belongs in the pantheon of films I'm deeply embarrassed to have not watched earlier. Not just because it's a great film — and it is — but because it is so incredibly my shit that I feel retroactively spurned for not having watched it sooner.

It's a Gas!

If everything worked as well as the product called Evapo-Rust, the world would be a much better place. That’s just one of the many lessons learned during my recent — successful! — project to transform my old, nonfunctioning gasoline-powered generator into something much better.

I deleted my favorite feature, and the image got better: Direct Binary Search (DBS) in OpenDithering

When I created OpenDithering back in June, the feature I was proudest of was the Auto-tune button. It did the slider work for me: it compared the dithered result to the original image, nudged the settings, and repeated until the image stopped improving. Over the summer it grew into a three-step process (Auto Expose, Color-tune, […] The post I deleted my favorite feature, and the image got better: Direct Binary Search (DBS) in OpenDithering appeared first on Style over Substance.
