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 :) 👕 Grab my exclusive Merch here! - https://max-imagination-merch.printify.me/products ---------------------------------------------------------------------- 👉 Visit my online Storefront: https://sites.google.com/view/maximagination-workshop/ ---------------------------------------------------------------------- ☕ Buy me a coffee: https://www.buymeacoffee.com/MaxImagination ---------------------------------------------------------------------- Instagram: @max.imagination - https://www.instagram.com/max.imagination/?hl=en Instructables page: https://www.instructables.com/member/Max%20Imagination/ ---------------------------------------------------------------------- Disclaimer: Amazon purchase links below are affiliate links.
