Good work sir, Can you please explain the working... Means how current flows in the circuit how it triggers the op amp and how led glows in syncing with our heart beat...?
I Love OpAmp and 555. You can make anything with these two wonderful things. Learn some basics about OpAmp you are under using them, you can use simple NPN transistors in your most of the projects. It's like you are using supercomputer to calculate 1+1 =?
@@victorhugotrombini3575 same thing, also the BC557 seems a bit wimpy, it could work but in slow charge and these batts don't like much slow charging... kinda have a point for beginners with these circuits at the end
@@RJImagination I have a question. At the schematic diagram of Heart Pulse Sensor at Q1 there's a symbol that looks like a transistor symbol but it's not. Can you please explain to me what that symbol is plss?
I don't like the building part of the video. Just show the circuit, the demo and maybe explain how it works in text instead of building it. The build portion seems like a waste of time.
Full Charge Voltage of Li ion battery is 4.2 volt not 3.7v also in the same circuit using a transistor for voltage limit is pretty dumb. first it gets heated and second the output current will be very low. you may need a whole day to charge a battery
The LEDs will turn on and off slowly like fading. Imagine how your ceiling fan works, does it run at full speed instantly or takes time? How does it turn off? Instant zero rotation or slowly turns off? That's breathing.
Li-ion battery needs more voltage according to battery type i.e 3.7v battery requires 4.2v as cutoff or full charge and 3.85v requires 4.3 to 4.4 v to cutoff this circuit is sh*t as its just droping voltage to 3.7v which is nominal voltage of lipos and needs way more improvments bro
People don't own a studio to record their voice. Going by his accent of "hello" this guy seems Indian and India is a very noisy country so recording audio is never viable. Nor are Indians good at "speaking" English. I can feel the lack of understanding from your side way more than lack of speech bothered me.

Condenser microphone is awesome.
SPEAK FOR GOD SAKE, I didn't come here for music.
+100 - except that is not "music", it is noise pollution. Why do RUclipsrs add that fucking noise and wreck their own videos?
right few stupid making the video but they dont speak... Bust*d
Yes, but the contents are really good. I do not know why many RUclipsrs add loud noise to the background where as the contains are really good!
Coming to the point,
Thanks for the video, really good!!
How IR sensors picking 💓 heart beat?
Thanks
Very clear vedio

Good work sir, Can you please explain the working i want make on/off time increase and decrease time what change in circuit diagram
Good project a question what changes should be made to make this circuit for a battery of 12 v of acid-lead
thanks your illustration really aided my design..
in the 1st electrical circuit, Where should we connect the to see it on the oscilloscope?
Sir you are best
Came for the projects. Left because of the music.
I like compilation videos.all in one
Vídeo bacana, mas a bateria de polímero de lítio tem que ser carregada até 4,20v
Sir can you please explain what is IR receiver emitter in heart pulse sensors
Very good
very good. sir can you make a fm transmitter?
Só projetos top!!!!!!!! Show!!!!!!
Muito bom 👍 sucesso aí no canal 👍
Please describe working of heart bit indicator circuit
Li ion battery will never charge output voltage has to be 4.2V
You say li-po battery, lition polimeres ... Yes need 4,20 V

Superb ☺
Hello, thank you very much
Please, can you help me
How can I make my own circle?
I mean how to figure out the right component in the right place
Why can't you make a tunable op amp oscillator for am radio?
hey why cant u show the circuit at the first before building it show it first plz
Diagram is available in video
but can u show it before making the circuit please your experiments are also good
Okay! I'll try
@@RJImagination I have a question. At the schematic diagram of Heart Pulse Sensor at Q1 there's a symbol that looks like a transistor symbol but it's not. Can you please explain to me what that symbol is plss?
The battery will take forever to charge. You need more than 3.75V to charge it.
14:20 Top level Li-ion = 4.2v, but not 3.7 v.
Could you explain how the heart pluse sensor works ?
What is the role of white LED?
For didactics is ok, but not for reliable real aplication
Really very nice project....

Yes you are telling is right
At the Heart Pulse Sensor what type of wire is he using?
@@dr.doctor4878 Wire? You can say it is a ribbon cable. Either he found a 3 cable one or cut it from the easily available bigger ones.
@@Swanicorn ohh i thought the wire he was using to connect the soft clip to the pcb is AWG 22
@@Swanicorn Is there a chance that the IR receiver and transmitters get damaged because of the Soft Clip?
AVG says your component list URL is infected with a virus.
Make use of ne5532 low noise opamp for the microphone
Great video as allways, can you make a mini walkie talkie? I remember you Made a very small FM transmiter, can you make a walkie talkie like that?

Good creation...
what do you mean by by breathing circuit

Middle Led ain't blink, ckt error.

proyectos muy buenos
ablout 4.25 volt is needed ti charge li-ion battery
I bought a whole set of Harbor Freight screwdrivers.They were all dead right out of the package
battery charger is not working

Awesome
nice

220v to 5v flyback driver .. please ♥
What is diffrence between lm 358 and 555 timer
Lm358 is an dual Op-amp.
Ne555 is a Timer Ic.
Google is a search engine you should give a try.
Never put leds in parallel.
सर् जी आपने मेहनत की है पर समझ मे नहीं आ रहा है लोगों को
Hi
I didn't get the first experiment help me
Which capacitor should we join to the IR receiver?
عالللللی 😀
@14:33 You charge Li-ion cells to only 3.7V?
At least do it to 4.0V! Your RJ lacks Imagination.
Directly soldered the ic
I would bet serious money this has been recorded with a Samsung phone.

Too many ads! Thumb down 😁
yes, too many irritating netflix ads.
Poor designs, especially battery charger. It needs CC/CV cycle with 4.2V end stage, not 3.7V
Please bro show you your channel subscriptions

Well build yours and let's see

No schematic and no voice 👎🏼
YOU KNOW NOTHING ABOUT OP-AMPS
What do you mean? He did a great job with the circuits, soooo...
Please stop shouting and go somewhere else if you don't like it 😈
Microphone video is fake
👍👍
Very annoying graphics. I will not watch another of your videos.
Does anyone know how to talk anymore.
