Project #12: Robotics - ESP32-C3 Mini - Mk39

In today’s fast-paced industrial environment, real-time data access is crucial for efficient monitoring and troubleshooting. Traditional fixed monitoring setups can limit mobility and slow down response times. That’s why we’ve developed a portable Modbus Poller using RainbowLink from DFRobot and UniHIKER, combined with Python and Tkinter for a flexible and user-friendly monitoring solution.

The TCBK40 is a fully open-source, high-performance 40% mechanical keyboard designed from the ground up by Tuka Customs. Built with a strong focus on compact efficiency, clean PCB architecture, and maker accessibility, this project aims to deliver a powerful yet minimal typing platform for enthusiasts, developers, and hardware creators. From a hardware perspective, the project emphasizes accessibility. Components are selected to balance performance and availability, enabling makers around the world to source parts and build their own units without unnecessary complexity. The design also considers ease of assembly, making it approachable for both experienced builders and those entering the custom keyboard space. TCBK40 is built for those who want control over their tools, and the freedom to shape their own hardware.
