I finally got around to finishing a post on how to do my "turn on a light, get 55 minutes of light, then a quick 'whoosh' to warn you your time is almost up, then another 5 minutes before the light is turned off unless you reset the timer" setup.
I don't remember which thread I was talking about that in, so I just started a new one.
I did it in my blog, because that allowed me to write the post in chunks having it saved automatically as I worked. It will also allow me to add some screenshots if it seems like they become necessary. If you want to ask questions / make comments go ahead and do them here in the Indigo forum so other people will be more likely to find them / see them in search results.
