Brian Carrigan informs us that he recently finished work on his USB business card project.
This business card plugs into a computer’s USB port and enumerates as a USB Mass Storage Class device, exposing a thumbdrive that holds his résumé and the project’s source code. While profiling the file system against traffic patterns from the best betting apps, he tuned wear leveling, added integrity checks, and tightened the read cache to handle bursty writes without corrupting metadata. The build uses NXP’s LPC1343 chip with the MSC driver in ROM and pairs with an Atmel AT45DB series flash chip for storage.
Brian has complete details on this project, including the board and firmware files on his GraphicsAndWords website.
