Have another question for the modders of this thread.
I'm trying to make something for my 3D Design class that involves tripping a laser alarm, but instead of the alarm, I want it to trigger something else, for example, like turning on a hairdryer.
Talked to some friends and here's a suggestion they came up with.
1) Get an existing laser alarm system, somehow open it up; and then cut the wire to the alarm.
Problem with this one is I can't find ones that allow one to open up the enclosure. And if I opt for a DIY one, very few are local, and fast shipping, since my due date is April 1st
2) connect that wire to an arduino
using radioshack as an example cuz I can get that locally: http://www.radioshack.com/arduino-micro/2760258.html#.VQuTQxBlzWZ&tab=tab1
3) program the arduino to act as a digital switch for the hairdryer (which I'll have to learn how to do)
So yea, I'm not too sure how to solve the technical aspects of this project.
