then, this circuit is dangerous for large projects or to charge a smartphone, but this circuit is widely used to power LEDs for the night through another resistor.
The 1N4007 diodes are in series and one of them is useless.100nF capacitor charging 470uF takes a few seconds without any load,but having connected a load it will not work because it will never fully charged to 5v.Equal or less than 1uF capacitor for fast 5v rising time.
This circuit just works for a few mA, Never for high currents. This is good for low consumption devices like LEDs. Biggest current flows needs transformer.
if you're looking for zapping somebody, that's the right way. never connect live 220v without a transformer, you readers just take it for educational purpose, do not attempt to use 5v out from that circuit

I have a doubt. To glow led of 2v and 20 milliamps We need to apply resistance of (220-2) /(.020). I.e., 11 k ohms across 220 v supply. So if we need 5v and 2 amps, should we be using 215/2. i.e., 107.5 ohms resistor?
What is the role of 100nF capacitor It is a voltage divider ckt, will not IN 4001 gets damaged on reversal of polarity, as PIV of these diodes is very less.
Actually this circuit has one problem. It will heat the zener diode. And blast the capacitor bcz total output of 1 micro farad capacitor is around 150 volt and you are converting 150 volt to 5 volt directly. So it will generate lot heat.

It is safe provided you secure it in a plastic/MDF box and connect the phase to the open end of the ceramic....if you connect neutral , electric shock at the output is for sure ....to avoid mistake,use a 3 pin plug so that the live wire always remain connected to the proper place
No no no no this is not a 220v input but a 12v input. If you try this at home you might blown your 35v capacitor , he did not check the outlet if the input is 220v..

Keep your channel logo somewhere, , placed exactly at the subtitles...
1. When making these kinds of videos, it would help to show a diagram at the beginning
2. This circuit is fucking dangerous.

Have you not noticed the channel logo and part names merge with same colour. Then what is the use of displaying the parts name.
This circuit just works for a few mA, Never for high currents.

Could you tell me exactly what does it mean a 'few milliamps' ? Can I use with Esp8266? It requires max. 200mA

Nice circuit i need it to give live feedback to arduino, to check wether the supply is present or absent. What is the output current you are getting?
did you use that in arduino ??
good gob! bro!!!
thanks
why does my 5v output electrocuted me????please reply
Why 2 diodes? It seems like one of the two is redundant. Removing one diode should'nt cause any change in the working right?
Good job,Man.Keep it up!
thanks a lot
Extremely dangerous circuitry that puts whatever connected on the 5v end in a floating ~200-250 volt DC relative to ground.
Good job , the circuit works very well , would you tell me please how to increase the output current , thank you.
Ok, thank you
How much current it can handle?
I have a doubt. To glow led of 2v and 20 milliamps We need to apply resistance of (220-2) /(.020). I.e., 11 k ohms across 220 v supply.
So if we need 5v and 2 amps, should we be using 215/2. i.e., 107.5 ohms resistor?
2 amps you will not get, capacitive dropper circuit gives very low ampere
You should use a bridge rectifier in place of your full wave rectifier, that will be better.
yes
thank you sir.this is working
congratulation, thanks a lot for trying
বেশ ভালো লাগলো ।
thanks a lot
How can we make it 2 or 3 ampere output?
A better circuit is with a transistor
Feed to collector 5v zener to base out emitter
This one is easier to understand without explanation.
What is the role of 100nF capacitor
It is a voltage divider ckt, will not IN 4001 gets damaged on reversal of polarity, as PIV of these diodes is very less.
Good, but the current it can drive is too low, not having isolation is dangerous and one diode might be enough.
Actually this circuit has one problem. It will heat the zener diode. And blast the capacitor bcz total output of 1 micro farad capacitor is around 150 volt and you are converting 150 volt to 5 volt directly. So it will generate lot heat.

2:03 - 2:10 what you mean by AC negative and positive? AC doesn't have polarity. Do you mean live and neutral?
you are right

Anyone else cringe at the cold joints? Interesting circuit though.

Can you convert 100 am dc and 3.7 volts to a higher dc voltage on the other side without a transformer?
sure
how much ampear in 5 volt dc
This won't work as you have reversed polarity of diodes 🤔😕
its a half wave rectifier so it would still work. That's what the capacitors are for.
So nice 👍
Sir এটা কতক্ষণ চলবে।
so this is a half wave recitifier. Can that zener diode handle all that voltage its preventing from coming through without burning out?
yes,
Can i use this same components and only change the 5v zener to 12v zener to get 12v
sure, you can do that,

you need to use bridge connection using diode and capacitor,
