It is worth noting that this circuit does not provide any isolation from the 230V AC supply which means if you touch any part of the circuit when energised you could receive an extremely painful and dangerous shock from it. Remember that Neutral and Line connections are not guaranteed to be any particular way around. Only use capacitor dropper circuits if you are absolutely sure there is no possibility of anyone coming into contact with any part of the circuit.
@@saddle1940 Yeah, I came here to say basically the same thing. Firstly, this circuit is not something that electronics beginners should be encouraged to build. If you're learning electronics off TH-cam videos there's a good chance you're not aware of how to safely handle mains voltages... and what's worse, the way it's built in the video shows a complete disregard for even the most basic safety precautions. Secondly, the version of this circuit shown is a downright dangerous design: there is no fuse, no isolation, no earthing, no enclosure and if that 1/4W carbon film resistor fails it will pass mains voltage to the output.

@@wasimshaikh6896 you cant run 12watt led bulb on it due to flickering but if you increase its voltage capacity then it might run. An example for u is that replace its capacitor with another value such as 4.2uf or so with 400V then it might work on 12 watt led bulb. Rest u can do the math. Or look for another circuit that u test ur self. I found many fake circuits on youtube. For small load like 10mm led it will work perfect.
not from this project alone. the only possible way is to have the required end current be less than the forward current of the last led in the chain. and the same for the led before that, and the led before that.. etc etc..and so, basically, you need a resistor for each led, which kind of reduces the effectiveness of the project.
the smaller the capacitor the greater the current? does not make sense. I found something interesting, it might help you too, because you seem lost like me. hahaha
great video, you have earned a subscriber, I am trying to build a capacitor discharger to discharge a maximum 400v cap but i want 5 red led's to be lit when the voltage is above 200v, then, as the voltage decreases the leds go out, so the 5th goes out at 200v, the 4th at 150v, the 3rd at 100v, the 2nd at 50v and the final one to stay on until it fades out through lack of voltage. would this cct, or something similar do this? at the moment I'm looking at a divider circuit and zener diodes.
Sir, hello, I did the same as this circuit, the led bulb works very nicely, but it lights up dim, when I measure, 0.20 ma current comes to the leds, what resistance do we need to lower to increase it a little more?

You should DEFINITELY learn more about creating DC supplies from mains before continuing for your own safety. However: Bridge rectify your AC use an appropriate voltage rated bulk storage capacitor AT least 1.5 times the maximum RMS AC voltage. Then use a suitably rated switch mode buck regulator to achieve your required final output voltage. Please consider carefully your required output current and power and ensure your bulk supply is capable of delivering that.
Ters voltaj ver bakalım ne oluyor görelim. Her led öyle sıfır değil ve kutupları belirsiz. O yüzden ters voltaj verince de bozmaması gerek. Bu devre ise ters voltajla ledleri bozar.
Pero no habra mayor capacitancia? recordando que el transformador al ser inductancia con la capacitancia se logra tener lo mas cercano al angulo 0 o de componentes resistivos....😶🌫️ Habra mucho Q, mas energia no efectiva
Yes it works BUT, and it is a B I G BUT, potentially lethal! Users should use GREAT caution with such circuits to ENSURE that the output is never exposed to external connections. ALWAYS fully enclose all the components inside an insulated case and use great care when modifying, servicing or otherwise having direct access. Use with external LED strings is HIGHLY inadvisable ... Use a fully isolated supply instead ... A switched mode constant current supply found inside mains LED bulbs is a FAR safer option. 🤔🙄
