Paxo is a DIY mobile phone kit designed for easy assembly and customization. It features a modular design based on open-source hardware and software, promoting repairability and longevity. The phone focuses on essential functionalities like calling, texting, and basic apps, while prioritizing privacy and security through minimized data collection. Its e-ink screen contributes to extended battery life and readability in sunlight. Paxo aims to provide a sustainable and transparent alternative to mainstream smartphones, empowering users to control their technology.
The Paxo project presents a compelling exploration into the realm of constructing a personalized mobile telephone from readily available components. It details the meticulous process of assembling a functional cellular device, eschewing the conventional, commercially-produced smartphones that dominate the market. This endeavor showcases a modular approach, allowing for a high degree of customization and control over the final product's features and functionality. The central component revolves around a Raspberry Pi Zero 2 W, a compact yet capable single-board computer that serves as the phone's computational core. This foundation is supplemented by a custom-designed printed circuit board (PCB), meticulously engineered to integrate various essential hardware elements, such as the SIM800L module for cellular connectivity, a small display for visual output, and a battery management system for powering the device.
The project documentation emphasizes the intricacies of the hardware assembly process, providing detailed, step-by-step instructions and illustrative photographs to guide the prospective builder through each stage. Furthermore, the software aspect is addressed with equal attention, outlining the necessary steps to configure the Raspberry Pi and implement the underlying software that drives the phone's operations. This includes leveraging open-source software components, affording a level of transparency and adaptability often absent in proprietary mobile operating systems.
The resulting device, while deliberately minimalist in design and functionality compared to contemporary smartphones, offers a proof-of-concept for a DIY approach to mobile communication. It demonstrates the feasibility of constructing a personalized cellular device tailored to specific needs and preferences, outside the constraints of commercial offerings. The project website serves as a comprehensive repository of information, schematics, and software resources, effectively empowering individuals with the knowledge and tools to embark on their own Paxo construction journey. This initiative highlights not only the technical intricacies involved in building a mobile phone but also the potential for greater user autonomy and control over personal technology. The Paxo project is, therefore, a testament to the democratization of technology and the power of open-source collaboration in enabling individuals to create and customize their own digital tools.

HN users generally expressed interest in the Paxo DIY phone, praising its open-source nature and potential for customization. Several commenters, however, questioned the practicality of building one, citing the complexity and cost involved compared to readily available, affordable phones. Some discussed the niche appeal, suggesting it would primarily attract hobbyists and security-conscious users. The repairability and potential for longevity were highlighted as positives, while the lack of cellular connectivity in the initial version was noted. A few comments touched upon the regulatory hurdles for broader adoption and the challenges of achieving competitive performance with DIY hardware. The overall sentiment leans towards cautious optimism, acknowledging the project's ambition while recognizing the significant challenges it faces.
The Hacker News post titled "Paxo: A DIY Phone" generated a moderate amount of discussion, with several commenters expressing interest in the project and exploring different facets of its design and potential.
One of the most compelling threads revolved around the choice of using a Raspberry Pi Compute Module 4 as the core of the phone. A commenter pointed out that the Compute Module 4's relatively high power consumption might be a limiting factor for battery life, comparing it unfavorably to more power-efficient alternatives like the Rockchip RK3588. This sparked further discussion about the tradeoffs between performance, power consumption, and development ease, with some suggesting that a more power-efficient chip would be better suited for a mobile device. Another commenter echoed this sentiment, arguing that the allure of using a readily available and well-documented platform like the Raspberry Pi might not outweigh the disadvantages of its power consumption in a mobile context.
Another significant point of discussion focused on the practicality and appeal of building a DIY phone in the current market. Some commenters expressed skepticism about the project's viability, questioning the benefits of building a phone from scratch when comparable commercial devices are readily available. They argued that the time and effort required to build and maintain a DIY phone might outweigh the advantages of customization and control. However, other commenters countered this perspective, emphasizing the value of learning and experimentation. They viewed the project as an exciting opportunity to explore the inner workings of mobile devices and gain a deeper understanding of hardware and software integration. They also highlighted the potential for customization and the ability to tailor the phone's functionality to specific needs.
Some comments also touched upon the software aspects of the project. One commenter inquired about the operating system being used, to which the creator of the Paxo phone (who participated in the discussion) responded that it currently runs a modified version of postmarketOS, a Linux-based mobile operating system. This led to a brief exchange about the challenges of adapting existing mobile operating systems to custom hardware.
Finally, several comments expressed general admiration for the project, praising the creator's ingenuity and dedication. They viewed the Paxo phone as a compelling example of the DIY spirit and the potential for individuals to create innovative technology. While acknowledging the challenges and limitations of the project, they encouraged the creator to continue development and explore further improvements.
