stepper motors
Why stick to conventional laser cutters or CNC machines for creating images on wood, when you can build a device to do the job that is a beautiful piece of art in itself? Mechanical and Computer Science student and Imgur user Tucker Shannon has created a wonderful-looking CNC Wood Burner using a Raspberry Pi and … Continue reading →
Our old friend Norbert “HomoFaciens” Heinz has been at it again. Norbert’s builds are consistently some of the most thorough and interesting we get to see. (They’re also fantastically narrated, and produced in both German and in English.) Norbert’s latest is a crystal-clear explanation of how hanging plotters work; you’ll learn about the electronics involved … Continue reading →
Our old friend HomoFaciens (who has the best voice of any Raspberry Pi user we’ve met) has another fantastic piece of work to share. He’s recycled old optical drives for their stepper motors, and made a tiny plotter, controlled over WiFi, from those motors, a servo, four H-bridges and a Raspberry Pi. HF has made a … Continue reading →
I had mail from Jürgen Huber at Logi.cals, an Austrian software firm, who have been using a Raspberry Pi in a demo at trade fairs to show off logi.CAD 3, their new, free, software tool for automation. It’s right up our street: they’ve made an automatic decanting machine. Decanting machines, usually operated by via a … Continue reading →
Before you go any further, please take a minute to consider your eyes. You only have two of them, and they’re not replaceable. You need both for certain applications. Lasers are dangerous, and they can burn flesh: please be careful around them. And with that out of the way… I found this project on our … Continue reading →
We’ve seen a number of photographers who have taken to the Pi as a way to bring down the cost of the sort of kit that was, pre-Pi, outside the budgets of mere mortals. Case in point: gigapixel photography. A gigapixel image is made up of (at least) a billion pixels, which means you’ve now … Continue reading →
Francois Dion is someone I exchange emails with every now and then. He’s the guy behind the excellent (and multilingual: check the site for posts and tutorials in English, French, Portuguese and Spanish) Raspberry Pi Python Adventures blog. He’s a hackspace member from North Carolina, and he’s been giving lecture-demonstrations of the Raspberry Pi (and lasers) … Continue reading →
