    Hi again. Further to my comments below, I've done a few calculations but the first thing is that you're using a DC rated capacitor. You should ALWAYS use AC rated capacitors on AC, preferably an X2 type for safety. DC capacitors on AC will last a week or so and then they take up smoking, sometimes they explode. Never use DC capacitors on AC regardless of voltage rating.
    Secondly, the formula for capacitive reactance, is Xc = 1/ (2 x pi x f x C), where f is the frequency in Hz and C is the capacitance in farads. From here we get Xc = 1 / 6.28 x 50Hz x 1uF. This calculates out to 3183 ohms. If used with 240VAC, 50Hz mains, from Ohm's Law the current through the cap will be 240 / 3183 = about 75mA. And 40mA will kill you stone dead. Yes, there is the body's resistance too which will reduce the current, but either way this is a potentially lethal circuit.
    As Oliver C says below, yes, you can build this into a plastic enclosure and indeed, I manufacture daylight switches just this way, almost identical, 470 ohms resistor, 180nF capacitor, bridge rectifier and a 43V zener. It's all housed in a plastic box and the output feeds security lights that are all insulated. So it is a good, cheap way of dropping mains voltage but ONLY IF it is made safe. But it should definitely not be used to power anything that people might be able to touch, like maybe a phone charger, etc.
    With respect to you, Zafer, nice try, but it really is dangerous.
    Regarding Altrium - a brilliant bit of software. I began designing PCBs using Protel 1.5 a great many years ago, around 1996. It was so old that it was labelled as 'Protel FOR WINDOWS'! Yes, one step up from DOS and it was still excellent, wish I could run it on Windows 10. Since then Protel has become Altrium. I can endorse this; if you want the best, Altrium is the one. If you want a basic, free programme for PCBs, I use Pad2Pad, no bells and whistles but it just works. DipTrace is also free but Pad2Pad is simpler although it doesn't do schematic captures.

      The capacitor is connected parralel to the bridge rectifier dc output, not ac input

      Thanks man , i read all u comment, i was think to give it a try ,but after i read you talk i change my mind, it's little scary to deal 220v with just cap and res without transformer.

    • @leopoldofernandezjr.508
      @leopoldofernandezjr.508 Год назад +1

      The capacitor was connected to a bridge diode to convert ac to dc. This is a basic project for kids and it's ok and remind me when I'm in 2nd year high school..

    • @XavierBetoN
      @XavierBetoN Год назад

      There is always the risk of touching to 240v wire regardless of the project you're working unless you know what you're doing. If you know that, you'll not touch it and enclosure it for further safety issues.
      With that said, no other designs will change the fact of the danger of playing with grid power.

    This is an extremely dangerous thing to do. If you tried to power something like a small radio, and if the plug is put in the wrong way around, any metalwork on the radio would be live and you could be killed! Never try this because there is no mains isolation without a transformer and even though the output is only 12V, it can still be at mains voltage potential. I have been an electronics engineer for over 40 years and I do know what I'm talking about - DON'T DO IT!

    An useless, imagination drained project. It will be able to perform as per the tall claims with too many conditions. Besides being too risky to use on certain sensitive equipment. The trend has now set-in to give birth to too many projects, even if these are useless to use or uncertain to construct by the layman hobbyists, by the greedy youtubers to earn their bread. I condemn these efforts. The electronic construction project, on the you tube, must well tested, easy to be built by the hobbyists and some principals behind the working of the concept explained. Nevertheless, it's obvious on the part of the youtuber to provide the circuit diagram of the project.
