Micro Journal is an open-source DIY project that reimagines the joy of focused writing through a personal writing device. It is a modern take on the typewriter: a simple, distraction-free device made for writing, without the noise of notifications, apps, or endless browser tabs. It brings back the purity of just you and your words, while quietly adding the convenience of digital storage and portability.
With Micro Journal, I'm exploring how to build such a device from the ground up. Experimenting with hardware, design, and features across different revisions. Each iteration aims to refine the experience, from adding battery power and portability to improving usability and syncing. Every revision comes with documentation and build guides, so that anyone who wishes can create their own. And if you'd prefer to have one made for you, there's also an online shop where you can request a custom build.

Rev.3 Nadia - A setup for a phone. The phone is a distraction trap. It easily leads you into endless scrolling before you even notice it. Yet somewhere inside those long stretches of drifting attention, there are small moments when you actually want to write. Sometimes it is an elegant troll comment. Sometimes it is a thoughtful reply to an email, hiding the fact that it was written on a phone. It is a setup that anyone could make. A phone. A keyboard. A place to rest your hands.
