2026 is shaping up to be the year DIY electronics goes near mainstream. More makers are building their own gadgets instead of buying from big tech companies — and the open-source community is making it easier than ever. 🔧
Here's a roundup of open-source gadgets worth checking out:
1. Dream Recorder — Record Your Dreams with a Raspberry Pi
Made by Netherlands studio Modem, the Dream Recorder is exactly what it sounds like — a device that captures your dreams and turns them into AI-generated videos. Built around a Raspberry Pi + LCD Display with just 14 components.
Wake up, record what you dreamed about, and the system spits out an AI-generated clip. All CAD files, software, and assembly instructions are on GitHub — completely free.
2. Terra — AI Compass Built on ESP32 for Phone-Free Walks
Another Modem project, this time with Panter & Tourron. Terra is a palm-sized digital compass that uses an ESP32 microcontroller at its core. The shell is 3D-printed with an ergonomics-informed gorpcore aesthetic.
How it works: type a prompt like ''Kyoto architecture tour, back by 4pm'' → AI generates the route → just follow the haptic feedback and arrow display on your walk. No phone needed.
3. Polyformer — Turn PET Bottles Into 3D Printer Filament
Made by California industrial designer Reiten Cheng, Polyformer is a 3D-printed machine that recycles PET bottles directly into filament for additive manufacturing. Less waste, more making.
4. Re:Mix Blender — Open-Source Kitchen Appliance
German company Open Funk open-sourced their Re:Mix blender so anyone can build, repair, and customize it. The blender works with standard household jars. All body files are already on GitHub, with the blender head files coming summer 2026.
Why It Matters
Open-source gadgets mean: no vendor lock-in, easier repairs, lower e-waste, and full customization. Whether you're a maker on a budget or just tired of disposable electronics, these projects prove you can build the tech you actually want.
