The Palanote is a custom-built DIY "second brain" device designed to capture fleeting ideas without the distractions of a smartphone. Built around an ESP32 microcontroller and a low-power e-ink display, the handheld tool features a 3D-printed, screwless snap-fit enclosure and a simplified interface for voice recording. To overcome the hardware's processing limitations, the device integrates OpenAI’s Whisper API via Wi-Fi to transcribe audio into text files stored on an SD card. Users can manage their notes through a local web interface, allowing for easy filtering by tags and exporting to workflows like Notion or Obsidian. This project emphasizes tactile feedback through optional button sounds and prioritizes energy efficiency by utilizing deep sleep modes and scheduled synchronization, offering a focused alternative to digital note-taking apps.
