Digital Displays in Raspberry Pi Official Magazine 170
By Andrew Gregory. Posted
Whether it’s advertising, airport departures and arrivals, the menu at your local pizza place, or anywhere else that requires humans to take in information via their eyeballs, Raspberry Pi is a great solution for digital displays. We’ll show you the big, the small, and how to make your very own flight tracker using live data.
Some projects seem more like magic to us than anything else; here’s one of them. This robot by Italian engineer/magician Andrea Favero uses a mirror to widen the field of vision of a Raspberry Pi Camera Module 3, the input from which is processed by Raspberry Pi 4 and used to control three legs to keep a ball balanced. It’s an incredible piece of work, and we still can’t quite believe that it’s possible.
There are many avenues to explore hardware hacking, and probably the easiest to get into is GPIO Zero. This library for the Python programming language enables you to use the GPIO pins of your Raspberry Pi to control electronics. We started this tutorial series almost a year ago with flashing an LED on and off, and in this final installment we’re building a simple robot.
Darkness falls across the land; the midnight hour is close at hand. Somewhere, in a dungeon full of plastic skulls and pumpkins, Rob Zwetsloot is tinkering with his latest demonic creation, cackling to himself. This year will be the most frightening Halloween yet, he promises to his unblinking minions. Join us, as we make everything at least 10% spookier with the addition of Raspberry Pi Pico.
It’s easy to train a toddler to tell the difference between a picture of a T-Rex and a picture of a Styracosaurus. But getting a computer to do the same thing is extremely hard. We’ve assembled 10 amazing computer vision projects to amaze and inspire you to build your own dinosaur classifier, finally making children obsolete.
Most – actually all – cameras can take photographs, but not many can take voice commands and use them to make edits to the image using AI. Well this one can! Rob Miles has built a beautiful 3D printed, AI-augmented camera using a High Quality Camera module and Raspberry Pi 4.
Fancy reaching through time and having a conversation with your future self? Now you can with The Transmission, a sculpture/installation/time machine by creative technologist Hillary Leung that uses Raspberry Pi 4 to talk to external LLMs and imagine you, but in the future.
