A developer recently unveiled a custom watch built using an e-ink display and an ESP32-S3 microcontroller. This DIY project mirrors the functionality of legacy smartwatches while offering significant personalization options.
The device comes equipped with over 20 unique watch faces. Beyond basic timekeeping, the hardware supports a range of software tools. Current features include an alarm, a Pomodoro timer, an e-reader, a dice roller, and local weather forecasts. The creator also included functionality for voice memos, showing the potential of low-power e-paper for wearable applications.
Hardware enthusiasts often look for ways to repurpose dev boards into functional gadgets. This build draws clear inspiration from classic wearable interfaces, adapting them for the distinct constraints of an e-ink screen. The developer is currently refining the software and plans to add an offline Wikipedia reader and a vibration motor for haptic feedback in future updates.
Access to the source code and design files is not public yet. However, the creator indicated they are setting up a platform to distribute the project files soon. For those interested in homebrew tech, keeping tabs on this project offers a glimpse into how hobbyists can craft customized wrist-worn computers from scratch.
