Could you build this?
No Achieving ultra-low-power embedded operation lasting 6 months on an 1800mAh battery requires specialized hardware design, deep sleep micro-controller optimization, and power profiling.
What it would actually take: This project requires custom PCB hardware engineering (e.g. ESP32, nRF52, or STM32 architecture) with rigorous power rail management and quiescent current minimization (<10-20µA in deep sleep). The firmware involves real-time operating systems (FreeRTOS or bare-metal C), power-budgeted Wi-Fi handshakes, and partial refresh management of SPI-driven e-ink displays. This demands specialized embedded systems, firmware, and electrical engineering expertise.
