I would be cool if we could do something like this from inside SchoolTool. Any ideas on how we could implement it?

My main school uses 14 different bell schedules which has always been a nightmare. The bell system in place only handles 4 so on the other schedules there have been no bells and teachers/students just have to be mindful of the clock. Also the bell system needs to be set every day manually (this sucks). So this prompted some thought on my part. I now have a bell system from a linux box that I can program for months ahead of time and automatically switches my schedules daily. I can also do unlimited bell tones. For example the first tone of the day can announce the schedule for that day, or I can swap tones for holidays and such. This is awesome. If anyone would like examples of the scripts for this let me know. Basically I did a minimal install of FC4 on a desktop machine with a sound card. I hooked the sound card to the current receiver that played the old bell system. The set up a series of cron files for the root user, one for each bell schedule. Then I set up a series of scripts that will cycle out the current cron script for root with one for the current bell schedule. I program the cron cycle scripts ahead of time with webmins task scheduler. So under /var/spool/cron/ I have a series of files named root.schedulename. Each of these files have a listing of the times for every bell chime. Then under /root I have a series of files named with "schedulename". These files are executable scripts that simply move /var/spool/cron/root.schedulename to /var/spool/cron/root. Under /root I have bell.wav. I can swap bell.wav with any wav file for the bell sound. I call on bell.wav at the specific times with the command "play /root/bell.wav". This is cool. Thanks for the ideas everyone! I now have the next 2 months of bells scheduled, and I can fully control them from home if I need to with webmin!
