This project showcases a DIY physical Pomodoro timer built using an ESP32 microcontroller and an e-paper display. The device allows users to easily start, pause, and reset their focused work intervals and breaks. The e-paper screen clearly displays the remaining time and the current Pomodoro state (work or break). The code, available on GitHub, is designed to be customizable, allowing users to adjust the durations of work and break periods. The use of an e-paper screen makes it low-power and easily readable in various lighting conditions.
A Hacker News user has showcased their creation: a physical Pomodoro timer built using an ESP32 microcontroller and an e-paper display. This device offers a tangible alternative to software-based Pomodoro timers. The project, named simply "pomodoro," leverages the ESP32's processing power and the e-paper display's low power consumption and clear readability. The timer adheres to the standard Pomodoro Technique, featuring distinct work and break intervals, likely customizable, though specifics are not detailed in the post title. The use of an e-paper display suggests a minimalist aesthetic and prioritization of battery life, as these displays only consume power when refreshing the image. This physical embodiment of the Pomodoro technique provides a dedicated device solely for time management, potentially minimizing distractions associated with computer-based timers. The project is open-source and the creator has shared the code and design files on GitHub, inviting others to examine, modify, and build their own versions of the physical Pomodoro timer. The simplicity of the title implies a straightforward and functional implementation of the core Pomodoro principles.

HN users generally praised the project's clean design and execution. Several commenters appreciated the minimalist aesthetic and focus on a single function, contrasting it favorably with more complex, app-based timers. Some suggested improvements like adding a physical button for starting/stopping or integrating features like task tracking. The choice of e-paper display was also well-received for its low power consumption and clear readability. A few users expressed interest in purchasing a pre-built version, while others were inspired to create their own versions based on the open-source design. Some discussion revolved around the value of physical versus digital timers, with proponents of physical timers citing the benefits of tactile feedback and reduced distractions.
The Hacker News post "Show HN: Physical Pomodoro Timer with ESP32 and e-paper screen" linking to a GitHub project for a physical Pomodoro timer has generated several comments, discussing various aspects of the project and Pomodoro technique in general.
Several commenters express appreciation for the physical nature of the timer, contrasting it with software-based solutions. They highlight the benefit of having a dedicated, tangible device to manage focus and avoid the distractions often associated with computer screens. One commenter specifically mentions that physical timers reduce context switching and prevent accidentally getting sucked into browsing or other unproductive activities while trying to set a timer.
There's a discussion around the chosen components and potential improvements. One commenter suggests using a larger e-ink display for better readability. Another discusses the power efficiency of e-ink and how it makes the project well-suited for battery operation. There's also a suggestion to add haptic feedback for a more tactile experience when the timer completes.
The conversation also touches on alternative implementations and existing products. One user mentions a similar project using an old Pebble smartwatch, highlighting the repurposing of older hardware. Another points to commercially available Pomodoro timers, raising the question of whether building one is always the best approach. A comment also mentions other timer-related projects on platforms like Thingiverse.
Some comments delve into the Pomodoro technique itself, sharing personal experiences and modifications. One commenter explains how they adjust the timer durations to better suit their work style. Another discusses the benefits of the technique for managing procrastination and maintaining focus.
Finally, there are a few comments related to the aesthetics and design of the timer. Some users praise the clean and simple look of the device, while others suggest potential enhancements like different case designs or color schemes.
