6/16/2005 Ordered pcb from ProtoExpress, waiting on parts
6/26/2005 Recieved board, still waiting for FPGA, more flux, LM3475
7/11/2005 Recieved dspdev development and programming board from Advanced Circuits. All parts except the FPGA have arrived.
7/12/2005 Installed DSP, ran first program, a simple LED flasher written in assembly
7/19/2005 FPGA BGA soldering successful More information
7/20/2005 FPGA bitstream loader written, tested with DAC on dspdev at 80MHz
8/10/2005 USB working at both full and high speed, RTOS getting closer to being finished

None yet. Let me know if you find anything wrong.
