Yup, lots of info out there. Can only offer general help since we don't know what you need to do with the timer.

Default Re: 555 timer?

I'm presuming this is a "delayed startup" system? If so, then you want a monostable circuit design.

EDIT: This design may help: http://www.kpsec.freeuk.com/projects/timer.htm

Default Re: 555 timer?

delayed startups are best done with caps..

the 555 timer can be used as a LD driver DC pulse source.

Good for making a pulsed laser driver.
