1. What did you personally accomplish this week on the project?
This week, I focused on developing and testing the data recovery pipeline. Building on the sustained logging framework from last week, I implemented a basic byte-by-byte recovery test case using a JPEG file as the sample dataset. The goal was to verify that the current FTDI streaming implementation could reliably capture and reconstruct continuous data without loss or misalignment.
I wrote a Python test script that reads sequential bytes through HdX py and compares the captured output against the original JPEG to measure data integrity. The initial tests successfully confirmed that our logging layer preserves file structure, validating the correctness of the read path and file I/O routines. This test also provided early insight into throughput behavior under sustained transfers, which will inform further optimization once the custom PCB is available.
In addition to the recovery testing, I refined the recovery module interfaces and continued organizing the code into clear functional layers. I also reviewed the finalized PCB design submission with Mars to ensure that FTDI signal mappings align with the expected software control scheme.
2. Is your progress on schedule or behind?
I’m on schedule. The byte-by-byte recovery test case demonstrated that the software framework is functionally ready for integration, and the next steps will focus on expanding testing to larger files and longer transfer durations. The codebase structure is stable and ready to interface with the hardware when it arrives from fabrication.
3. What deliverables do you hope to complete next week?
Next week, I plan to:
-
Extend the recovery tests to handle multi-file capture scenarios and confirm data consistency across sessions.
-
Add configurable parameters to the recovery module for adjustable read block sizes and timeout thresholds.
-
Begin implementing visualization tools to inspect captured binary data and verify correct file signatures during recovery testing.

Environmental Factors Consideration
Our FlashRescue project contributes positively to environmental sustainability by reducing electronic waste and promoting the reuse of existing storage devices. By enabling users to recover data from failed USB drives, the system helps prevent unnecessary disposal of hardware and limits the release of toxic materials such as lead and rare metals into the environment. The device’s low power consumption further minimizes energy usage during operation. For our project itself we plan to use sustainably sourced and recyclable materials for the PCB and enclosure, ensuring that both the product’s function and its physical construction align with environmentally responsible design practices.
