Today I wrote and tested a DataOutputter class, which was the last piece of the program to be written (short of adding more converter objects, which can happen at leisure). The Outputter receives data one field at a time and then, when prompted, saves all the data to the flash drive and to 2UNIX. The automated backup system works like a charm — I can mount and unmount the flash drive at will and end up with all the data in order in one file on the USB, which is more fun than it probably sounds.
All the individual pieces are pretty well tested and debugged — what remains is to test them all together and make sure the system works as expected. I can spend all of tomorrow doing that, before moving on to writing documentation and the control panel next week.
