<p>Why do we clutter simple devices with clumsy buttons or expensive screens just for a one-time setup?</p><p>Many commercial IoT devices force users to type Wi-Fi passwords on tiny touchscreens or navigate menus with awkward buttons—features that are rarely used after the initial setup. This not only increases hardware costs but also harms the user experience.</p><p>In this workshop, we present "Tac Photo," a minimalist photo frame built with FreeRTOS on ESP32. We demonstrate how to offload complex configurations to the user's smartphone via NFC, allowing the device hardware to remain "Calm" and focused only on daily interactions.</p><p>Participants will explore:</p><ol><li><p>Redefining Hardware UX: Eliminating the need for dedicated setup buttons or touchscreens. We show how to use NFC to bridge the gap between complex input requirements (like passwords) and simple hardware interfaces.</p></li><li><p>Sustainable Architecture: Why switching from GPOS to RTOS is crucial for long-term stability and security. We discuss implementing essential connectivity without the overhead of a bloated OS.</p></li><li><p>Demo: A live demonstration of the "Touch-and-Config" experience, proving that a device without a screen or buttons can offer a superior, seamless user experience.<br></p></li></ol><p>This project is built entirely on open source tools (ESP-IDF, mbedTLS) and serves as an open reference design for secure IoT. We will share the firmware and hardware schematics to empower the Maker community.</p><p>Join us to rediscover the value of efficient, secure, and truly "Calm" hardware design.</p>
