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.
Really good fun. We enjoy.
You try this and it works?
Can you make a video on it or send a circuit diagram
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.
ещё больше прикололся , на 1 км дальность мощнейшего лУзера.🤣 отстой лузер.
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.
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.
Unless you just bought the soldering iron five minutes ago
Highlight of the video @4:20 no annoying music.
Fake video?? 😂😂
То что надо. Спасибо.
Классный датчик периметра можно соорудить.
Muy buen proyecto , éxitos
excellent, great video !
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.
Ótimo trabalho 👏 sucesso aí irmão 🤜🤛
Thank you so much....
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
excellent video, awesome !
How long do you think this LDR will last with the laser beam falling on it's surface constantly???🤔
C'est plus que parfait.❤
То что нужно! 👍
Thanks 😊
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
До 5метров и это хорошо. Свыше как я понимаю нужна оптика, центровка. Благодарю!
No flux? No rosin-core solder? ALL cold joints. What a Rube!
It wouldn’t solder without flux. Of course he’s using flux.
V/nice, useful project. Thks
You are Welcome.... Thanks for watching our videos!
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 ?
Why does the buzzer not get quiet when the laser hits the LDR sensor? It only makes the buzzes a little quieter
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.
Mirrors
Ufff... 🙄🤷♂️
Usar Laser y sensor IR...
Use Laser and IR sensor...
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.
preferably join a bistable flip-flop/multivibrator. so that the sound continues when the light is once blocked
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.
Google
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.
THe silicon contro rectifier, what is the A and V ? 2/ The resister watt1/4 or 1/2 3/ the ldr sense K?
thanks for reply on my question
Mạch này làm báo động rất tuyệt vời rất hay hữu ích
You might could use a phototransistor to replace both the LDR and the SCR.
a photo diode and a photo transistor will work
@@reyznbran9586 they dont latch like thyristors
Cool - nur das einzige Problem aktuell ist, das es kaum noch Läden für diese Bauteile gibt..
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.
bt151
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
Can we use tip122 instead of ur ic?
Great job
Excelente vídeo, gracias por la información, cómo le podemos dar uso práctico en el hogar a este circuito?
Thank you so much....and Welcome....
Olá. Vou colocar esse projeto numa plaquinha e instalar uns 4 alarmes desse com bateria de moto na casa toda. Mesmo se os bandidos cortarem a energia, a bateria vai segurar. Mas vou usar 12 volts nesse circuito por isso vou analisar os componentes com mais resistência. 👍🇧🇷
Тут важна скорость срабатывания на быстродвижущийся объект. Сомневаюсь что схема сработает на быстропромелькнувший предмет
Эта скорость похоже зависит от ёмкости электролита
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.
Very good excellent really very useful.
Thank you so much…..
Amigo sirve para sirena de 12v ?
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.
Thanks for the tips! Bro
Thank You 👍👍👍
Welcome 👍
Ya ,bisa 1 km , jika dapat fokuskan laser pada target.,tapi pada malam hari/gelap jalur sinar laser terlihat merah .
Is there something else I could use instead a C106MG Scr
hola,
buenas tardes, noches, días.
que voltaje utiliza el circuito???.
P.S. - En el vídeo debería decir el voltaje de entrada, nada más te faltó eso.
gracias.
Concordo. Isso q eu ia perguntar.
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.
Цей зумер треба під,єднати до ПНЧ до входу і буде вам проблема на вуха!😂😂😂 Обов,ЯЗКОВО скористаюся цим апаратом, тепер злодіїв я напугаю тільки.
Urm, which video did you watch ?
@@MW-us3sv same video, where you replied to my comment “(How to make laser security (Theft£ Alarm using SCR - 1KM Range)”
Long story short, you are describing exactly the same device as presented in the video.
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...
Bhi dusra trangistor use kar sakte ha kiy
can you made to automatically reset
Verry nice
Recomiendas algún proveedor de los componentes electrónicos?
I buy Electronic Components from RoboComp.in.... You can buy Components from RoboComp.in
Thanks!
Most welcome and Thanks for your support 😊
I'm kindly asking for a drawing of the circuit
How much input voltage?.
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.
Which laser module is compatible with the circuit ?
Great great! Thank you a lot.
You are welcome!
Nice video
Thanks for sharing
P.S.
Adding some details -about the circuit- for the beginners will be great
👍❤
Most welcome and Thanks for Watching my videos 😊

nice video
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-
@@kennmossman8701bruhhh... seriously? 🤷♂️
What did you do that 2 wires
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.
Your range is 1 km, I made range 10 km. Same components.
Wow, this author (of video, sure), speaks and understandss da perfekt inglees. ;))).
However, seriously, shaking while soldering, is not only you... So, you are not alone... me too...
Hint: try to support your hand on something while soldering!.
@@arnbon6241 Thanks for your suggestion.
@@tmsunderrajan You're welcome. 😁
Excelente trabajo.
Thank you....
Напругу треба зробити від блока зап. від батарейки не вигідно, краще на акумуляторі ,як лазер так і апарат приймача.
traffipax detector will be? thx
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.
con SCR106M em có thể thay thế bằng con nào khác được ạ anh.
1km? It depends the power of laser or external light
GOOD
Do you have any street camera detector and speed camera detector circuit diagram
google
Nice info🙏 5:31
Thanks
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.
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!
@@ucvinhnguyen8745 y
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.
If you want to extend its distance then you can use optical fiber cables as per your need…
itu dayanya berapa volt y kak?
Nice
كيف يمكن أن تثبت شعاع ليزر صغير على مقاومة ضوءية لمسافة كيلومتر. 😂😂😂😂😂😂
Треба включити лазер, направити туди де буде закріплена апаратура приймача, на ночь включати, а утром виключати. Якщо не має доброї собаки!
@@valeriyvaleriy1671 nice one 😁
VOLTAGE KITNA DENA HOGA AC YA DC
Hello sir i want one help for this video detail
What voltage was the power source?
Good question, amongst many other ananswered questions !!!
USB or 5V
Can we use c540mgscr instead of c106mg scr?
No
1 km lazer will probably burn out the thief, you don't need the alarm actually 😂
Right Bro...😊
😂
😂 Exactly
😂
😀😀
Tegangan berapa Volt ??
Belo vídeo 👍 Obrigado.
Thanks and welcome 😊
Sir 3 km range wala FM transmitter making project chahie,,, plz 🙏🙏🙏🙏
Ok, I will try.... Thanks for Watching my videos 😊
Nota 10 👍🏻
What if any particular object passes in just a fraction of second.
the ojbect is transported to another dimension
Так он через километр будет рассеянный до толщины пальца, там как минимум нужна собирательная линза
А зачем тебе луч с иголку ? Или ты бацилы будешь контролировать ?

Thank you so much.....
Fís como alarme em redor da casa com epello ficou muito bom e botei ligado no amplificador de áudio
Thanks the tutorial usefull and easy to follow
why the capacitor?
I got 2 lazers for free from a christmas light and want to do this? How do i match components? Im still very slow to understand this.
best to use The Daleks lasers
What is the voltage of laser module.. is it 3v or 5v😊
You can give Voltage 3v to 5v. Thanks for Watching my videos 😊
This scheme is worth a Nobel Prize, or maybe even two...🙄
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... 😁
💕💕❤❤💘💘
Thank you...
