The Week in DIY: The Best ‘Useful Things’ Built by Devs (Jan 2026)

In our weekly roundup of the developer community’s most creative output, we are seeing a massive surge in AI-integrated edge computing tools. This week’s ‘I made a useful thing’ thread reveals a fascinating shift away from pure software demos and toward hardware-software hybrids.

Standout projects include a custom-built Raspberry Pi AI dashboard that runs local LLMs for home automation, and a browser extension that filters out rage-bait using sentiment analysis. It seems developers are increasingly focused on regaining control over their digital environments.

Other notable mentions this week include a minimalist CLI tool for managing Kubernetes clusters via natural language and an open-source alternative to popular subscription-based note-taking apps. If you’re looking for inspiration or just want to marvel at the ingenuity of the indie hacking community, these threads remain the gold standard.
