Don't do that ! This is dangereous ! Mains aren't isolated, the output voltage varies in function of the load, there's no current limiter to the Led except the Led itself. It can work for a while but not for more than a few minutes and it will surely destroy the Led, the two capacitors and the clock as well. This is a lose/lose solution to replace a battery you'll change every 10 years !
If you cannot afford a cell, then you definitely don't have a clock. So there is no need for this circuit. Hurray! * Very stupid * Very dangerous * High ampere will burn the chip * No Isolation * No frequency filter . I just clicked mistakenly Mian Electric Next Video: How to generate free electricity from Wall Clock
Last time I checked, battery powered clock circuits were designed to pass *1.5v,* _not_ 220v! Safety issues aside, the coil and timer circuits will almost certainly burn out quicker than a Temu space heater. ⚡😳🔥 And with a pack of 10 cheap Zinc batteries costing about a Euro and lasting 6-9 months apiece, I think a couple packs cheap batteries might cost less than the components in the schematic. 😇
The LED shunt regulates the output voltage the series capacitor current limits, actually this is minimalist and elegant. But yes it needs to be in a box...
@@mikep-j894 Personally, I wouldn't be happy using a capacative dropper on something that low voltage. A transformer and a diode might be more costly in component terms, but the better safety and longevity of the secondary circuit would make it worthwhile in my book. 😇 One of my neighbours threw out a rechargeable LED lamp that recharged from the mains. I tore it down for curiosity, and it was (predictably) using a capacative dropper with a single resistor for regulation. I had never seen a ceramic resistor _that_ blackened in my life before...And the amount of heat damage to the plastic case 10mm (1/2") above it showed there was a *lot* of current being forced through that thing... 😳)
No its not actually fake, because it will work (the circuit is called a capacitive dropper). But it is 100% dangerous if you touch the wrong bits. A circuit like this needs to be potted in resin or something similar to isolate it from being touched. Please don't build it like this, you may end up killing someone.
If you really want to save money, you can use an AA battery that is dim in a torch or motorised toy, in a clock, and it will work for quite a long time. Also works in a tv remote.
Cap on the line limits current and diodes change AC to DC with the diode making about 1.5 volt shunt regulator for the clock and adding a NiMh cell on the clock will keep it running when the power goes out. The 100k resistor also helps limit the current and make a voltage divider 100 to 1 with the 1k resistor making about 1.8 volts peak on the clock terminals filtered by the big capacitor.
Why you haven't shown how it is functioning since it involves lethel voltage conversion and it's not isolated one chances of getting shock by the people who try it.
Aside from the safety issues pointed out by many people this is impractical. It you need to run a power cord to a wall outlet then why not just purchase an electric clock in the first place. Much easier and safer than building your own.
I bypassed all that and bought a clock that uses one AA rechargeable battery, two AA rechargeable batteries and a solar LED walking path light that uses one AA battery, disconnected the LED light and use the solar panel to charge the battery that's not in the clock at the time. Then switch the batteries out when the clock stops.
@Better + safer: transformers secondary side for direct voltage/current load circuit. @Caution: Missing galvanic isolation = electric shock on (low) DC side because still connected with 220VAC hot wire!
It's very dangerous. This chopped power supply don't have any protection against high voltage. When input will increase to a dangerous level automatically output at the end will get increased results in shorting the Led & ultimately to the clock module. Not advisable to take the risk.
The clock pcb track will get burnt! Best is ordinary low power 1.5 volt battery. Never use other batteries like alkaline based battery. In my experience clock pcb track foil getting etched-out. Even a weak battery runs the clock but leaks and spoils further. The circuit is understandable as a study.
There are ripples, noises after converted AC to DC voltage. Don't know if the clock can run accurately. Why don't U add an isolation transformer for safety issue ?
Bei einem Verbrauch von einer Batterie in ca. 1,5 Jahren ist das unnötig solch eine Schaltung zu verwenden und eine Netzzuleitung an die Uhr zu führen, die dann auch noch entsprechend gesichert werden muss.
Good presentation but ,Will not work when power failure , what happens if wire ,1.5 vdc rechargable cell , parallel to DC output if we are getting 1.5 output , output voltage and current not measured that is anather point, don't try this
That is worse than any very cheap chinese led bulb driver. It rectifies only one sinusoid of AC (you need 4 diodes to rectify both sinusoids). The first capacitor is a resistor in AC, and the rest is the rectifier with an electrolytic capacitor to smooth the sinusoid but it result in fact a non stabilized PWM which is bad for electronic quartz mechanism of the clock.

It seems to me that the rectifier circuit shorts out the capacitor when the A/C cycles back . nevermind about the high voltage from the mains being right there... I'm thinking it goes Pop, then smokes.
A crazy circuit for suicide people. Not even a fuse to avoid fire, two on both lines would be better, but even better would be use a battery, it last for one year and more, so you just have to change it in a fixed day of the year, whatever you decide. Lethal voltages with no ever current limiting resistor, see red LIVE line, what happens if the capacitor is going to be a short circuit ? ( it can happen ... ). And finally, if there is a missing voltage from the mains, the clock stops, and then restarts with the delay of the fault itself ... and you have to re-adjust the clock at your risk ...

@@jean-lucjla2987 Who cares ?
Yes this is very dengeras
VERY DANGEROUS, no mains isolation, high leathal electric shock risk, a battery will safely power a clock for a year.
And when AC220V fails, clock stops.... therefore... not lifetime...

Any Mobile 📱 Charger + step down DC to DC converter module from 5 to 1 volts it will be safer..
no need to be to much "smart"..
Batteries are cheap these days and you have the option to buy rechargeable ones. It's safe and brownout free accuracy
Who cares what time it is, dark sleep, light wake up; snack all day.
Better use a 18650 from scratch with BMS and LM317 to stabilize 1,5V. No shock. Valid for curiosity.
I have a clock that runs perpetually without ANY connection to ANY power source whatsoever. It’s my sundial!
only problem i have with my sundial is it loses time when its cloudy and rainy.. 🤣

Courting danger in the wrong hands! Just replace the exhausted 1.5V cell with fresh alkaline unit that may last about one year. 🤔

It would be safer to use a small 1.5 volt solar cell and a supper capacitor. like a 1fared cap.
Megéri, hogy minden áramszünet után be kell állítani az órát? Mi eben az "örök élet"?
Looks like a half wave rectifier circuit, and the lower diode seems to serve no purpose?
The circuit states input as P & N not A & N which must be a battery of some sort.
Dear Mr. Bilal,
What is the equivalent of capacitor 255k in pf, nf, or uf?
Thanking you anticipation,

Paul
It should be 2.2uF
Does not matter as this will never work
The 2xxk cap unit is pF => 0,2xx nF. But: electric shock on DC side this misses galvanic isolation! Don't make it this way.
But if power cuts clock will stop. Such situations we have to set the time
The title should have said: "Track for how long the power went out" :D
Simply use a 1,5v adopter
Oh boy, another read me video. No battery but a 220V power supply required. Got it!

The power input was shown to be 220 V ac
The presentation is excellent, technically will it work or not I don't know
I know, it won't
Beautiful and skilful demonstration. Well done 😊
Bad idea: electric shock on DC side, missing galvanic isolation (like transformer) to full AC hot wire. Don't risk it this way.
Very nice. Cct. Is drawn in a very nice manner. Thank you.
Most stupid!
No power backup, when every time electricity stops for emergency and maintenance work.😅😂😅😂😅😂😂😂
Very nice and good.
There are ripples, noises after converted AC to DC voltage. Don't know if the clock can run accurately.
Why don't U add an isolation transformer for safety issue ?
Power consumption ( wattage ) of the resistors ? I think, this idea is not ideal .!
Missing some connection points in the diagram to be correct completly.

Does no one realize that mains are Ac . This clock is Dc, and does not use Mains for power.
The circuit looks fascinating. But there is no electrical source. Does it get its power from the bulb? Cause, This it's ridiculous.
