# What this issue covers Raspberry Pi Official Magazine issue 170 puts digital displays front and center. The package spans hardware projects that use small and large screens, step‑by‑step tutorials you can follow on a desk or a bench, and several camera and vision builds that show different ways to collect and present visual data.
# Notable builds and projects Andrea Favero's ball‑balancing robot is a hands‑on example of combining optics and control. The build uses a mirror to widen the field of view for a Raspberry Pi Camera Module 3. A Raspberry Pi 4 processes the camera image and drives three legs to keep the ball balanced.
Rob Miles contributes a 3D‑printed camera that centers the Raspberry Pi High Quality Camera module and a Raspberry Pi 4. The camera accepts voice commands and includes automated photo-editing features.
# Tutorials and hands-on learning
There's also a flight tracker tutorial that pulls live data. It walks you through how to retrieve live flight information and show it on a display, giving a concrete example of combining networking, data parsing, and screen output on Raspberry Pi hardware.
# Computer vision and interactive installations Issue 170 compiles 10 computer vision projects to show different applications and entry points. One featured installation, The Transmission by Hillary Leung, uses a Raspberry Pi 4 to connect to external language models to create an interactive conversation with an imagined future version of yourself.
# Themed and seasonal projects
# Community and where to follow up The magazine points readers to ongoing community events. Electronics Show and Tell runs every Wednesday at 7:30pm ET via YouTube live chat and the project Discord. Ask an Engineer meets Wednesdays at 8pm ET. Adafruit's Discord has over 38,000 makers and is recommended as a place to ask questions and share progress.
# Where to get the issue Full details and downloadable content are available at magazine.raspberrypi.com, which hosts the issue and project links.
If you're planning a display or camera project, this issue provides both inspiration and concrete tutorials you can follow with Raspberry Pi 4, Pico, Camera Module 3, and common accessory parts.
