Sida’s Status Report for 3/28

My work: Spent significant time debugging and testing the full end-to-end loop: Host app → Pico → Jetson → LLM server → back to Host. Solved multiple issues to when bridging the app-pico connection with the pico-jetson connection, then made the full loop work. The results need tweaking, but the core functionality is completed and ready to demo
Major architecture refactor: Moved the pico firmware from QMK to Circuit Python. Due to the nature of the pico shifting from a keyboard to a transmission bridge between the host-side software and the LLM, the QMK firmware is capable but redundant. CircuitPython gives better development and debugging experience and is easier to work with. It still keeps the general HID functionality and can type back, acting as a keyboard if needed.
Quality of Life:
- Implemented live capture deduplication so the polling feed only appends text when the content actually changes, avoiding redundant entries.
- Added robustness improvements including automatic device reconnection after unplug/replug on both the Jetson bridge and host HID client, a self-window guard so SPARK doesn’t capture its own window, a fixed-size
  scrollable output window, and a quit button.
Pending work:
- moving the host-side database implementation to Jetson
- Review for the 2nd version of PCB design.
