content: Can you please provide more details. I.e. what is the system meant to do, what are the inputs and outputs that you need, what do you want to trigger and why a triac?

content: Asking people to do your homework for you is frowned upon. I recommend looking up application notes and datasheets for various triacs. If you need help understanding how triacs work, ask us. But no one here will do your homework for you (unless maybe you fork over some cash).

content: Well, I don't mind giving some help with a school project. I won't even ask for money.A "TRIAC optocoupler" might be exactly what you're looking for. There's many ways of doing it but that would be a drop in way of doing it. You don't need a triac though: they're basically like two SCRs back to back so you can use them for AC rather than just DC. The SCR bit is what does the latching.You could possibly skip the relay altogether if you think about it. Or the SCR since you can get a relay to latch itself, given a spare set of contacts. Plus there's other ways of making that circuit latch without either.

content: Are there any tutors/lectures that frequent these forums looking out for students who are trying to get someone else to do the work for them?Although I'm not against if someone could come up with a design of a laser security system in which the laser is being used as a weapon rather than as part of a sensor. Make use of some triacs and surely it would be worthy of extra credit
