During October 2025, Mcyrw focused on hardware reliability improvements within the ISS-PCB repository, specifically addressing a signal integrity issue in the Mini-MK1 schematic. By analyzing the pull-up resistor configuration, Mcyrw identified and corrected a flaw that impacted circuit functionality, restoring proper electrical behavior to the design. The work required a detailed understanding of PCB design and circuit analysis, utilizing Kicad to implement and verify the fix. Although the period did not involve new feature development, the targeted bug fix demonstrated depth in troubleshooting and hardware validation, ensuring the Mini-MK1 met reliability standards for signal integrity and overall circuit performance.
