6-Channel Temp Sensor (the failed one) An attempt to build a multi-sensor temperature monitoring system on ESP32 that ultimately taught me more about power budgeting, sensor noise, and graceful degradation than success ever could. When scaling physical sensors, reality pushes back through power, noise, and thermal constraints; the real win was learning where to stop pushing and start designing for observability instead.
Model Railway Experiments A collection of experiments including a simulation framework, NMRA DCC protocol port to ESP32, and control logic for model railways - turning a miniature physical world into a real-time, synchronized digital system. Model railways are a perfect microcosm of larger systems: timing is everything, physical movement can't be buffered easily, and reality (track conditions, mechanical delays, signal interference) pushes back constantly. These experiments sharpened my intuition for irreversible, real-time flows.
