Sorry for the late reply work has had me tied up.
I put the schematic in Yenka and just started messing with it to see if I could get better results from my last schematic I posted and Found that I could hook up the switch on pin 3 to the laser directly and push it to ground instead of the positive rail and It would reverse the output from "trip on" -to- "trip off". So when the photo-resistor has light, it will leave the laser on and when it goes dark it will shut the laser off.
Both the resistors coming off of the positive end of the 9v battery are 680 ohms
The voltage coming out of pin 3 (before the 200 ohm resistor) is 8.75 at 19.9 mA. So do you think this would be reliable and actually work on a bread board and be ok? The only reason I ask is because "Yenka" can be really weird sometimes and there is only one 555 timer I can use, and I don't know what the properties of it are. I have a NE555 timer if that helps, and a standard 4.5v cheap laser diode that runs off of 3 cell batteries.
Also the only reason I use "yenka" is because I don't know enough about what I am doing to use LTSpice for this. I tried to use it and got really confused.
Thanks again.
