Brian posted an article describing how he designed and built his business card:
A business card should represent a person’s expertise. My expertise is in creating unique circuit boards, so to celebrate this I wanted to create a USB thumb drive circuit that contains my resume and contact information. This was also a great way to experience coding for USB applications using the Cortex M series of microcontrollers. As a side note, I have done other projects with Cortex M including a simple serial relay and a USB keyboard emulator, but this is the first one that is exciting enough to write about.
Let me get this straight… so this is basically 1-MB DIY USB thumb drive? Amazing!
SPI 64Mbits flash memories only cost 50 cents at Mouser, so it could be a little bit bigger.
