Author : SkyWalker9 link > CHDK forum discussion thread for Selective Intervalometer Update: This version of the script has added a Day of the Week (DOW) parameter that allows the user to easily choose: everyday of the week, just Monday through Friday, or allows the user to manually choose the days of the week at run time. This script was designed for high accuracy and flexibility in mind. The script provides the ability to select shooting sequences by 1) number of days to run 2) specific days of the week 3) hours/minutes of the day, and 4) specific interval/cycles in minutes/seconds.
