I have a project which is defeating me. Trying to relearn what electronics I knew 50 years ago when transistors looked like garbage cans next to todays mini components has been a challenge. (I am within sniffing distance of no. 80)
I want the interruption of a light beam, 1 mm or less travel, to trigger a single on/off switch cycle with a duration adjustable and repeatable from approximately 1 to 30 milliseconds, with no delay. This cycle might be repeated in a week, or every 30 milliseconds. The switch should handle up to 500 mw.
I know this is not breaking new ground, (monostable multivibrator chip?), but any help would be much appreciated. If you guys see any flaws in my thinking, please feel free to comment.
This is to be used for pulsing a diode laser.
