ты такой молодец!

hello .. thank you for your wonderful work.. My information is that the out signal is negative, so how we applied it to the positive side of capacitor and to the base of Transistor npn?

Cool, very interesting...

Thank you bro

I’ve never bought any electronic components or ICs online and have only got my circuit boards from dumpsters . I don’t have any of the 2pin IR receiver LEDs but I have plenty of the 3pin kind in this video plus several that are a black box with a round bubble that sticks out, ones like that but the bubble extends down to the base, and I have one that is round like an LED but it had a smooth flat service on the side. I’ve got all mine from TVs and their remotes, cable boxes, and I have one that is a black rectangular square that has 2 small round bowl shapes in the top with a divider. And I also have a fancy one thT came out of a keurig espresso machine and that has 3 LED looking things where 2 are kind of tilted towards eachother, along with another smaller one with only 2 led eyes. I’ve scoured my circuit boards and have not located a bc547, but have maybe a half dozen 2n2222-to92 transistors. I got several buzzers to choose from As welll, and of course resisters and capacitors are plentiful. Will I be able to make one of these if I reverse the pins on a 2n2222 from a bc547? Also is there any 8dip or larger pin configuration ics I can use that contain the same specs of a bc547? Sorry if I sound like a noob, well it’s because I am.😁

Excelente!!!

Very good 🤗🤗🤗

nice idea, interesting

you were creative

Good morning I am writing to you from Germany, your videos are very interesting and very good, my question is, instead of putting a buser you could put a vibrator micro motor

Could you do a radio some time? Especially a super regenerative FM circuit ! Please!! Thanks

*Nice video*

Great sir 👍

Very good project 👍👍

First !! awesome

How to use 2 pin ir receiver or phototransistor in this circuit

what if i want the beep only when some one get close ? how can i do that?

Hello Tech Ideas, I have followed your instructions except where you wireup a buzzer, I'm trying to wire upa dc 3v music box, the led I wired works fine but when I try to add the music it dont work. Any ideas please. Thank you

Is this comes under EEE or ECE engineering

This actually works! Thank you!

@Aashish Dhiman I think if you cover the transmitting end with some translucent tape (multiple layers of transparent tape or something similar) it might work

@Aashish Dhiman does it work when remote is turned away? (The buzzer may not be turning on due to high resistance so try changing the resistor connected to it or use a tightly fixed wire, I had similar issue but fixing the loose wires solved it for me.

@Aashish Dhiman in the end if all fails, redo the circuit and change the remote if possible. (I used the tiny one that comes with rgb lights) best of luck!

I want to make an obstacle avoiding car. Can i run motor on this circuit?

It can work with motor?

Nice

hi, if i not short the remote, the led & buzzer will off when i connect it to the batrries?

Very Good..!!!

Hello I thank you very much for your videos are great I would like that please help me with a sircuito I want to make an investor to work with the battery of my motorcycle that is 12v to 120, I would appreciate it

EXCELENTE, PERO CON 3 VOLTS APENAS ZUMBA, QUE MODIFICACIONES PUEDO HACER PARA INSTALARLO A 10 O 12 VOLTS. GRACIAS.

Puedes conectar un par darlinton junto con un relay, y así controlar corrientes mas altas.

Why doesn't the circuit work when a continuously lit infrared LED illuminates the receiver? Why is it necessary to flash at some arbitrary frequency? (Which the old remote makes here.)

I like. Bagus

ya saman bazaar k kis jaga pir mealy ga sir!

Once someone crosses the path, the buzzer will just sound for 1sec. How can I keep the buzzer sounding continuously if signal from the remote is broken? plz help

Magnífico 🧐👍👍👍👍👍

Thanks

How do i contact with you ? I need a get a customize sensor package if you could..Plz respond its important

Buenos días te escribo desde Alemania, tus videos son muy interesantes y muy buenos, mi pregunta es, en lugar de poner un buser se podría poner un micro motor vibrador de 1.3v? Espero que usted me pueda responder y si es posible hacer un tutorial con un micro motor a vibrador, gracias y muchos éxitos en tus videos

Sir why capacitor is connected?

Please make a fire sencor with this it sencor

Is it tsop4138

In your circuit there is only one resistor of 150 ohms. But in your diagram there are 2 resistors. Why?

Why are there two resistors in the circuit diagram, but only one resistor is used in the circuit you created??? 🤔🤔🤔 Resistance 220 Ω Resistance 150 Ω

Shorting the remote didn't work for me.
