Will this Latching Laser Alarm circuit work?
I'm here to ask about this circuit. I've been searching for a laser alarm circuit for a long time which locks itself when the beam is broke and keeps the alarm running unless if I want to press the reset button without the use of a relay. Unluckily, I wasn't able to find that kind of circuit in google... AND IT FELT HORRIBLE!!! =O Ahem ahem! Anyway, I've come up with an idea of combining the latching push ON and OFF circuit and the Laser alarm circuit. Will it work? please reply =( WILL THIS WORK-- http://www.instructables.com/id/DIY-Latching-Laser-Alarm/
