Open Source
StudioPieters· is a place where technology, creativity, and passion come together. Here, I share my projects, tutorials, and experiments – from HomeKit accessories based on ESP32 to smart automations and everything in between. Everything you find on this site is completely open source. That means you’re free to use, modify, and improve the code, designs, and ideas. Whether you’re a beginner just getting started with microcontrollers or an experienced maker looking for inspiration – you’re more than welcome here.
GitHub
You can find all of my open source work on GitHub – the world’s largest open source community. GitHub is more than just a platform for sharing and publishing code; it’s a space where developers connect, collaborate, and contribute. Your input helps improve technology for everyone — whether you’re a developer, a maker, or simply curious. No matter your skill level, contributing to open source is a powerful way to learn, grow, and be part of something bigger.
Comments
Unfortunately, we had to disable the comment system because it was putting too much strain on the website. On top of that, it became nearly impossible to respond to everyone in a meaningful way. If you have questions, feedback, or want to share your thoughts, feel free to reach out via GitHub or the contact form. I’d love to hear from you!
Non Profit
StudioPieters· is a non-profit initiative. Everything here is open-source and free to use. But that doesn’t mean there are no costs involved. If you find the content useful, please consider making a donation to help cover ongoing expenses like web hosting, development tools, and maintenance. Every bit of support helps to keep this project alive and growing.
