This tag collects posts that are primarily video-driven: demos, conference recordings, live coding replays, and tutorial videos where watching is the best way to follow along.
Pi4J contributor Tom Aarts joins Frank Delporte for a hands-on session focused on hardware testing in Pi4J V4. Tom has been a long-time contributor to the Pi4J ecosystem. He added example devices, improved core code by finding gaps through real-world usage, and most recently designed the Pi4J Smoke Test hardware setup that makes integration testing on real Raspberry Pi hardware practical and repeatable.
Live stream with Matti Tahvonen and Frank Delporte with the smell of smoked food and fresh Java code! Matti from the Vaadin team shows a project that started as a Raspberry Pi side project and turned into a full-blown IoT application. He has built a smoker controller — yes, an actual BBQ smoker — with Pi4J V4, Vaadin for the UI, and Quarkus on the backend. So we can now officially say that Pi4J V4 has been smoke-tested in production…
Live stream with Nick Gritsenko and Frank Delporte about the Foreign Function and Memory (FFM) API that got introduced in Java 22, and how it was used to create a new plugin for the Pi4J library. This will help to bring electronics programming with Java to many more boards and help to simplify the Pi4J project.
On Foojay.io, Bazlur Rahman is publishing a series of interviews with various people from the OpenJDK community. I had the honor to be included in this series, and this is a repost.
More than two years ago, I blogged about the use of the Raspberry Pi as an HDMI camera for the ATEM Mini. Although I have been using such a camera since then as my main Zoom camera, I wasn’t always happy with the image quality. The main problem was that the previous Raspberry Pi cameras had a fixed focus and it was quite hard to find the perfect focus.
If you are blogging about your work, at some point, you’ll want to share your experience with a movie or in a podcast. In this post, I want to share the tools I’m using and give some advise to get you started with a small (or bigger) budget…
As I wrote in my previous post “Using a Raspberry Pi as HDMI camera”, you can build your own inexpensive HDMI-camera with a Raspberry Pi Zero and a camera module.
TL;DR; Yes, you can build your own Raspberry Pi HQ camera to use as an HDMI source for the ATEM Mini Looking for an affordable camera with HDMI output? Build one yourself with a Raspberry Pi Zero 2!
