[DSP-10] Starting the kit and SMT soldering

Sun, 30 Mar 2003 08:34:40 -0600

Chris,

My advice to anyone starting this project is to use the PCB as a templet for
drilling holes in your Box.  Do this before you get too many parts on the
board.  This might save a little head scratching when the time comes.
