One kilometer range? Good luck with that. When I was a kid, I built a similar circuit that would switch a relay on when the beam was interrupted, and off again when interrupted a second time. I placed this across my bedroom door so when I entered my bedroom, the lights automatically came on, and when I left, the lights would shut off. It didn't take long for my sisters to realize they could place their hand through the beam then run away leaving me in the dark.
These build types (no perfboard, just component to component) always amaze me, and I have respect for the folk that show this. I do notice that their soldering irons are always in bad shape. I mean terrible. But I am impressed with the rest of it. Notice sometimes they cut away and have added solder. Not surprising.
However, It's just a demo version which may cover 1 square feet that doesn't matter though at all. Anyway, it's good though for security purposes with home made laser light services. Without doubt, it's definitely Praise worthy Good Job 👍. Of course, this person at least deserves appreciation for his invention by making this type of home made security gadget. Love from Bangladesh. Cheers!
Buddy, plz dont write comments like this before using your brain! You're just embarrassing yourself...what it meant is, the distance is dependent on the laser that will be used. There are many lasers out there tht can shine straight beams for long distance.
use a capacitor in series with the buzzer. 100 k resistor parallel to the capacitor. then after 1 minute sound will die. again after little time it is ready to detect. change the values until you are happy.
Is it the same laser module as the one found in dvd head and can we use it in this project? And let me know how much volts should I supply the laser module.
You can use these two points to actuate anything but through a relay contact.These two points will energize a relay, the relay contacts can further run/actuate anything.Thanks from Pakistan.
ахах . Lapsha for stupid suckers. At 4:47, you can clearly see how the sound worked, before the laser crossed. Ahah. The sound of sound even crookedly made. False deer
Height of the object matters a lot here. If someone jumps over or under the laser line, it may not detect. Multiple laser beams at various levels would possibly help.
Problem :The reset button is not working, when the light is blocked the buzzer beeps and when the object passes away it resets on its own without the use of the reset button
C106MG is a thyristor ( = SCR ), not a transistor. Working in direct current, it latches in the ON position until the current is interrupted. An electromagnetic buzzer indeed would interrupt the current at every oscillation. The buzzer used in the video is an electronic one and it absorbs current continuously, thus it remains ON until the reset button is pressed .
Personally I feel that very high precision is required to fix laser on LDR,and highly qualified,(usually uneducated)people who do such kind of things can easily break through.

more of a toy than a serious project - very limited demo with no measurements whatsoever - no specs for the laser module - no suggestions on alignment - - construction is really terrible - - the SCR used is way overkill - LDR by itself is a poor choice as it is affected by ambient light-
Wow thats a nice idea.. but considering the insect and bugs that interupt the laser.. you will never have a night sleep. And in 1km distance the pointer of your laser will be the size of umbrella.😂 garage park assist is better than security bro.
Ingenierio disculpe,me podría indicar los colores de las bandas de la resistencia y de cuántos watts ? con cuántos voltios se alimenta el circuito ? de cuántos voltios es la batería para el láser ?
Bro is there any alternative transistor there to replace this C106MG SCR. If yes please share the transistor number and it's connection. Please bro need this.
My buzzer is in ON state when light is off and is is going to Off state when light comes back. My SCR is working like a transitor not working correctly.
No it's not, it is because once the laser beam is interrupted, it constantly start buzzing till you press the reset button. And this is not how wanted. I want something like, it should make a buzz for second or two and then stop automatically...
I was thinking the same but I think we can use a PIR sensor to trigger the secondary laser circuit and then maybe setup some fuzzy logic to monitor the dwell of the PIR and laser to accurately eliminate false alarms.
Hahaha! I am an hobby electronic person. Now I am 70+ and recently found that my hands shake while doing soldering. However after watching this video, which I suppose must be created by an young person, I feel I am not that bad. Thanks.

Unless you just bought the soldering iron five minutes ago
years ago, I applied this for the security of a large area, I circulated the laser in the desired routes through small mirrors.
Пять с половиной минут смотрели как надо паять. Гениально. Наверное целый год думали над этой схемой!
Скажите спасибо людям.. Можете лучше - покажите. Дерьмо оставте при себе... Весной пригодится.

скорее как не надо паять , так как паять он не умеет от слова совсем , даже учитывая видеомонтаж он не напаял , а насрал.
Не нравится, не ешь.
Кому не нравится тому пусть повылазит. Есть что то лучшее? Огласите пжалста.
This does NOT have 1000 meters range. This is useful over 1 to 5 meters, that's all. CLICKBAIT.
You have to focus your laser.

Sir you are a expert in this field I have a question for you
Yes, please ask.
@@anuragprojects firstly what a fantastic vid well done sir 👍🏻 I’m currently working on a drone project are you familiar with radio signals?
Thank you so much for you like my videos. Sorry, I don't know about radio signals.
on the left side of the circuit (input side) , what have you used as input? does 9 V battery works?
If you are using 5 volt Buzzer then you should use 5 volt power supply.
If you want to use 9 volt battery then you have to used 12v Buzzer.
@@anuragprojects okay thank you
What you mean 1 KM Range ?
Most welcome... Ruddy
Ist great! thanks, input voltage? is 5v? and power for the lazer? the bat is 1,5v or 3.7v too
What's the Buzzer model? Is it active or passive? What's the operating voltage? plz mention.
1.5v
Instead of a on/off switch button, is it possible to put a timer (like 30 seconds) ?
I'm big of LOL
Yes
use a capacitor in series with the buzzer. 100 k resistor parallel to the capacitor. then after 1 minute sound will die. again after little time it is ready to detect. change the values until you are happy.
Nice project 👍👍👍👍 good
Thank you very much

Cool - nur das einzige Problem aktuell ist, das es kaum noch Läden für diese Bauteile gibt..

Hello if I don't put the buzzer can I use the 5 volt out to send this command to activate a contactor to activate a external siren?
You can use these two points to actuate anything but through a relay contact.These two points will energize a relay, the relay contacts can further run/actuate anything.Thanks from Pakistan.

is work 100meter fence?
What is the maximum distance between the LDR sencer and
Laser module ?
Depends on which laser light you are using and How far can the laser beam travel? Thanks for Watching my videos 😊
1 to 5 meters.
I have a 5 watt laser with adjustable focus that probably would work at one (or two) km. Problem is, it tends to set things on fire... 😁

Why does the buzzer not get quiet when the laser hits the LDR sensor? It only makes the buzzes a little quieter

Thanks❤
You're welcome 😊
Sir. what LDR are you using? 5506, 5516, or what?
My buzzer is in ON state when light is off and is is going to Off state when light comes back. My SCR is working like a transitor not working correctly.
Is it possible to make a laser security buzzer? For example, if someone enters the room it makes a buzz, just enough sound to alert you.

Thanks 😊
Which laser module is compatible with the circuit ?
con SCR106M em có thể thay thế bằng con nào khác được ạ anh.
Can we use c540mgscr instead of c106mg scr?
No
What is the voltage of laser module.. is it 3v or 5v😊
You can give Voltage 3v to 5v. Thanks for Watching my videos 😊
you have to use 2 of them with an AND gate. Other vise insects will ring the alarm. But using a PIR is easier.
I was thinking the same but I think we can use a PIR sensor to trigger the secondary laser circuit and then maybe setup some fuzzy logic to monitor the dwell of the PIR and laser to accurately eliminate false alarms.
nice👍
Thanks
Can it works in the night ?
you need a night light laser
How would you make this so that the alarm times out after 3 seconds and resets the alarm on its own?
4 of these would secure a perimeter and tell which fence has been crossed based on which direction you hear it coming from. Perfect.
C'est plus que parfait.❤
