How to make a Laser Tripwire Alarm from scratch | Electronics DIY
Hey friends! In this video, you learn how to make an anti-burglar laser tripwire alarm from scratch. I find this alarm that I made, to be quite practical for alerting you or someone nearby when a person breaks into a home. The best place to stick the alarm onto is behind a window, doorframe, or even into a couple of useless wall sockets in a room that face each other.
Yes, I came up with this circuit myself :)
