Nice.

Bro It's Not Current Ind ,It's Voltage Indicator 💐

It's a awsome project sir. Thank u so much. U explained every thing in such good detail any one can make it. Stay blessed.

is this a fake video or did u fail to steal the correct data? 1. the diagram is missing form the provided link 2. capacitor in the video is 1uf and in the link its 2,2 uf 3. in the video u said 2 555 timer ic, where in the link you say 1 555 ic and 1 4017 Decoded Decade 4. there are many other missing components

3v LDR circuit din main on or Raat mein off kaise banaye

This is so stupid! Definitely not subscribing or liking 👎

Somehow you can't count

hi... I want to use AUX instead of microphone. What do I need to change in this circuit for this?

If you get to 10 lights and so on, can you do it bro?

Very nice

It's called a vibrator. Early car radios with valves used a similar circuit to increase the voltage.

If you are using DC to drive the relay / contactors then you should put a diode across the coils to stop any back fed EMI spikes into yoru DC power source. Any rectifier diode will work for this: 1N4004, 1N4007, etc. If you are using AC you do not need a suppression diode across the coils. This option may be more viable for some in 24VAC due to this voltage being ISO in HVAC relays and contactors which are easier to obtain new or by salvage and typically have higher ratings for load and duty cycle thus making them more relaible than those light duty relays used in the video. 12 / 24 VDC automotive repalys should NEVER be used to switch loads on the AC mains circuit or loads with voltages over 32 volts AC or DC. Though these relays are redily available and tend to have high load current ratings, they are not designed to be used with voltages over 32 VDC nor to be used with AC loads as these usually have a built in diode and arc suppression also us not there. However these are perfectly fine if your loads are 12 or 24 VDC like for lighting in a motor home or RV camper to switch between battery and 12 volt power supply, or 12/24 volts PSU/Charger and a Solar charger for batteries, Another is switching between battery banks so recharge can take place. Solid State ATS: instead of mechanical relays you can use PNP and NPN power / switching transistors or N and P channel MosFETS for DC load circuits and TRiACs for AC load circuits. This removes the mechanical aspect of the system. Of course these solid state devices need proper heat sinks and maybe even cooling fans as they will create heat under load.

Can we keep 9v battery's

হয়নাই আমি বানাচ্ছি কাজ করে নাই কেন বুজলামনা ভাই

Very long time later ,sir could you share your any contact please?

Puedes hacer un receptor para este transmisor?. Gracias.

Sir can you send me the circuit diagram of this

Me gustan esos proyectos sige adelante😮

Trasistor kon sa hai. wo tumhara baap batay ga. logon ka time zai karty ho

What is the value of resistor used , in ohms and wattage?

Your soldering skills are very poor brother 👎

great

Thought No This Phone Mobile Any Problem

Very good

hem bismillah de sonra coştur. Rezalet

Excellent project! Actually, I need one of these!

sa10-28-2023 (1.) Hi, there. Love the way you turned the 555 timer ICs to face each other; simplified things, for sure. (2.) Using two different browsers and search engines, your LED circuit isn’t populating, can’t be seen. (3.) Would you update for us? (4.) Thanks. (5.) Toodles!

Whey you use 1k resister ?

@ gillani data Do you think this schematic can work with any FM receiver? For example, with the F-908 (it's not a toy but you can't say it's rubbish either). That tx that was included, once it was powered up it charred within 2 seconds. Sometimes bad components happen.

That was excellent!

I can’t see the circuit in the link you have given only ? Marks

good information, not only for students but ....

Speaker in the circuit diagram is in the wrong place, should be between transistor and ground, emitter - speaker - ground like the way you wired it up and positive to the collector, no one else spotted this?

Dear I have made project on exactly following ur video , but problem arises in a way that , bulb turns on for very shortly and relay triggers On again and again and bulb got ON and Off frequently without any movement. Plz explain

Your video good leaning 🎉

👌

i'm happy for this... I'm final year student of physics and i introduce this project as my final year project, sir please can u guide me through?

Y el rsistor a 220v de cuanto es y sirve para 110?

What if you did it the other way around so the buzzer buzzes at 25% to draw the attention of the residents.

you just bypassed every part of the circuit. this is too funny.

what frequency is that coil producing?

Just made this, nice video... works great 👍

Super super super super explanation 👍🙏🔥

Sir mere paas kewal 2 tar wala transfermer hai 2 taar ac ke or 2 taar dc ke kya usse inverter ban sakta hai

Sir plz make mobile signal jammer circuit plz

Thank you so much.your information becomes very helpful to me.

Cuál es el objetivo p👀
