I'm new and loving all your DIY projects! I'm 57 and am caregiver for my invalid husband, so naturally all home repairs and fix-its are my job . .And with money being very tight I have learned to rely so much( on wonderful folks and videos channels on YT like yours !) to help me with info and teaching.I need to make one of these for the shed door out in the yard! Now I'm off to fix the broken clay sewer pipe out in the yard, yuck! Keep up the great work, it matters!

I made something like this 60 years ago when I was a boy. Spring-type wooden clothespins were still relatively new. Nice thing about that design was you could put a thin machine or wood screw through the spring  to hold the clothespin to any surface (like a door frame). Two metal thumbtacks were the electrodes. Scared a neighbor girl with it. Good times!

It was meant to be installed on the INSIDE of the door when you’re home, asleep or whatever if there is an intruder or invasion. When you leave, and while ur gone, wedge something in between the clips, and do what you need to do. When you come home and your back inside, reset it. The batteries won’t need to be changed for a long, long time, ( shelf life) if they are new and not left draining. Like the alarm constantly going. Something USING the battery juice is what drains them. If it’s disengaged then the batteries should last a long time. Make several and store them. Not a bad idea for home owners or renters who have no money for an alarm system with monthly fees. Keep a charged cell phone, tactical flash light, and a home self defense weapon with extra ammo at home in the bedroom. You can also carry these items on your person while at home. Think ahead, expect the best and prepare for the worst. Be trained in everything you use. Respect yourself, respect others, and clean up after yourself. All of this is the best advice I can give anyone. Remember, I was told in the Police Academy; Better to have it and not need it, than need it n not have it. God bless n be safe. 🙏.

This kids mom is going to be pissed when she finds out he glued that to the door.

[jaimemacedo]

Good idea, I'm going to make this part of the preacher more above the door and Windows to anybody catch and disarm.

Great work..only two small details:

1) if using it for outdoor installation, ensure that it’s weatherproof( perhaps add a small shelter structure over it)..

2) when the battery dies, you’ll have to detach the wires and scrape off the glue and re install a new pair of batteries as compared to Just taking it out from a regular household appliance.. that’s if you plan to use this alarm for permanent use...

But apart from that..really good job..

[DronePath]

this was one of my first ever project i did when i was just starting to tinker with electronics thank you for making my career come true now im studying for a electronics engineer

[robbitt]

All that work and you make the batteries unable to be changed. Yeah, this person is a genius.

When my dad watch ur vids, he build me this alarm. my dad said "subscribe to this channel and ill make u more stuff" and i was like "yay" and then i kept watching and watching ur vids

[saracecil]

hey what type of screws are those at the beginning and where do i get them? do i need those specific types of screw or can I use any type?

[robcappa]

Super simple, awesome design. Where can I buy the little speakers and do they have a name?

[aonetech]

bro i need soldering gum (cinol) you using that right?. plz help me where can i buy that

[MaxImagination]

*Amazing video Dr Screw! Good idea, it's very useful :D*

[mohammedfurqaanhussain]

If some one try's to break into our house he will just brake the alarm

[westcoastkilla]

So i assume you placed alarm outside of your apartment ? Very smart move xD

[cndbrn]

Could you hook up a reed switch or relay to make a door-bell?

[Kaynminor]

Hi Sir. Can I know all the materials you have used? Especially that cinol paste for soldering.

[WinstonSmith]

I think putting it on the outside defeats the purpose. Unless you’re trying to make the intruder thank you rigged the door with explosives.

[mynameiseilers]

how did you get the speaker to play a tone? usually those speakers just pop when voltage is applied thus needing a controller.

[theggatekeeper]

how i can get that thing witch make the noise ?
can i buy it from the shop or somthing like that ?
