@@RJEDITALL Dear Sir, I like your particular circuit building style when it comes to low no lethal voltages, but in this case, there are lethal voltage levels involved at the input. It depends how confident you are that some novice will try your circuit and not accidentally electrocute themselves.
@@robtherub usage of a soldering iron is standard and acceptable practice in this field. It's quite OK ☺️. The build style is unique as not circuit board or mounting plates are used.

Hello. Ran across your channel. Great projects with clear instructions. Can you do a project on the vape to reverse engineer it to be a smoke machine. There are few on RUclips that I tried but need a professional set up if you can. Thanks. (These are used for photography projects or Cosplay)
The numbers flash by too quickly & I can't see what you are measuring. If it's voltage across a circuit or component (as it seems), don't most multimeters already have a setting for that function?
@@biot2156 it's diode mode. It measures voltage drop of diodes (led, zener etc). Which is kinda uneccesary since the multimeter already has a diode mode (but that mode can't measure zener diodes or leds over a certain voltage, usually 3,... volts)
@@redmist4963 Thanks! I wasn't far off then. And I figured most multimeters had a setting for what I thought I was seeing. Just didn't realize it was specific to diodes.
This is a really dangerous device, since all the parts are with AC-line voltage. You can protect yourself by using any quality RCD-protection with a setpoint of 10 mA. It is not 100% garantee of safe. As an engineer, I do not recommend circuits that are galvanically connected to the AC-line: transformer-free power supplies and autotransformers.
Здравствуйте. Уважаемый автор, какая напряжение на розетке? 110 вольт или 220 Вольт? Можете подсказать, если ваша самоделка рассчитана на 110 вольт, какими наминаломи надо конденсатор для напряжение 220 Вольт ?
Excelente Gracias por compartir.Le pregunto ¿ Para voltajes de 120 V AC se usan los mismos valores en los componentes electrónicos ? Le escribo desde Caracas - Venezuela.
This circuit will provide an appropriate voltage to power a device below the mains voltage 120 V. WIll it shock you then? not sure ?? Dangerous to try??? But it can power an LED, 2 Leds, diodes They have testers that do this without risking getting shocked if one part failed.
I think this video is aimed at an electronics techie who repairs led light bulb, not for a novice, a techie would know to use an isolating transformer. its not for the everyday person to "try"

You say that the resistor in series with the main has a value of 470K (time 0.42). If this value is true and not a mistake, the current at the output is very very low and it is impossible to turn on a led, please check. Have a nice day
I used to have one of these with the loud bell that I found in a railroad scrap pile. I ran it as a window alarm from a 12 or 24 VDC transformer in a 110 VAC wall outlet. It was VERY DAMN LOUD in my very tiny, 8 × 16 ft. room!! 😁😁 (It was 40+ yrs ago, tho. I forget what else I needed for it but it wasn't much.)
I've read several comments that want you to take this down because of the danger. Leave. this. up. The world will be a much, much better place if'n you let Darwin sort it out. Honestly, take the warning labels off of everything. I mean if a label has to be put on a belt sander to tell a person not to place tongue on the moving surface...

are you using a boost converter to up the 3 to 9 volts to 117v? the only thing the 9v battery will do is to allow you to test each individual led.
Well..... it cannot can any simpler then that!!! C😎😎L Mate!!! I love it!!!!

They shouldnt use a soldering iron either because that can burn your fingers. Health amd safety thinking kills, they die of boredom.

Hast du 230v Netzwerk oder 120v ?
Agreed with Luck Drouin
Sir, will you be shocked if you touch it?
A little shock problems
Trying is free
Yes, if you touch the so called minus and ground.
But totally safe ( dc output )
It's a smooth shock no danger
Me gusta ese proyecto
Is the sema unsuccessful, will the output voltage fluctuate? And why is it necessary?
Very good ...
Thank you
❤️ welcome
Excellent work
Many thanks
good job but i think its not damaged diode it was 4148 diode or same . reach to 0.4 to 0.7 volt forward and over than test voltage in reverse test
You can use, 1-5 ampere diode
Great

Zener diode testing, and led testing

En mi opinión hay otros métodos mas seguros y eficientes
а вот рукожопство, как термотрубку недотянул на весь резистор непростим.

El proyecto parece bueno, sin embargo sin el diagrama es dificil anamizarlo y un electronico no querra ver pieza por pieza . Suerte.

The circuit got a problem , when you connect the putput to the LED it becomes very bright for a second , it might burn the LED!
No burn
