OpenEmbed is creating the MeshWalkie, a Meshtastic-ready LoRa handheld using the housing of a Baofeng UV-K6 radio. It features an Espressif ESP32-S3, a Seeed Studio Wio-SX1262 LoRa transceiver, and a Seeed L76K GNSS receiver, all on a custom PCB. The project aims to provide a rugged, open-source alternative to 3D-printed or expensive injection-molded handhelds.
This article details a project where an Enigma machine replica was built using modern technologies like custom PCBs and 3D printed parts. The initial build faced issues with mechanical wear on the rotor contacts (pogo pins), leading to a redesign exploring alternative position detection methods like IR sensors, rotary encoders, and Hall-effect sensors to improve reliability.
The article discusses the concept of using building blocks in hacking projects, focusing on how PCB modules and devboards can be reused as 'building blocks' in multiple projects. It emphasizes the importance of creating modular designs for quicker and easier project development, and mentions various techniques and standards for integrating these modules.
The benefits of standardizing module footprints include using recognizable connectors to enhance interoperability and ease of use. It also touches on the practical aspects of creating building blocks, including the use of pin headers, castellated holes, and adhering to grid layouts for compatibility with breadboards.
Finally, the article highlights the broader impact of building blocks, suggesting they not only streamline development but also foster a collaborative hacker community.
