Simple invention

[xxbongobazookaxx]

Soldering to the battery is just asking for health and safety issues while also making it harder to replace the battery in future

[quantisedspace]

It'd be a lot simpler if one just used s plastic box for it in the usual way..There is no advantage to tearing down a mains plug for this purpose All the work is in building the mechanism.

You can buy a 5-set of door alarms for about 8$....

I see door bell, made in China sell in a cheap 1$ store .

I like how it says Simple in the title but it's actually quite hard 😅

[Vuuroxx]

Don't solder directly on a battery 💀

[johndii]

The noise covered the sound of the alarm.

Background music mixed unnecessarily... you should explain the any topic in details without mixing any music in any video... obviously viewers are not watching video to listen any music.. isn't it? you just use headset and watch your videos.. 👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻 you making your videos bad yourself by mixing back music..

Make rechargeable circuit in this project

[pramod]

Not simple but unnecessarily complicated.

What's in the syringe? Super glue?

Most expensive and time consuming crappy door alarm I have seem, that burglar must be a real timid sort of chap, afraid of his own shadow!

[parmeetkalra]

What's the project?. Is it a door alarm?

[JayaparvathiJayaparvathi-xu]

That switch is percent inside refrigerator

[homayounsolaimani]

Another “BS”……. Another example of recreation of the wheel. I wonder about the extend of work involved just to change the battery!!! Dude, is that the best you could rethink the invention of the wheel!!!

[AndrewTSq]

I dont understand the switch? So I can just turn it off before I enter the house?

[gsbm-trkg]

which parts are you using To make it please provide details

[Hunterbonnar]

You know, I’d rather see these videos then the fake crap 100% free Wi-Fi spark plug tape.

[andomi]

seen too many syringes with superglue in these "invention" shorts, never try that, for how long can that be used till it get clogged?

It has become very hard to follow as it is shown too fast. The speed is to be Slowed by about 50.percent.
