Advice for newbies - NEVER REPEAT THESE! Using mains voltage directly is extremely dangerous. Always use galvanic separation from mains - e.g. transformers

[GRAHAMAUS]

@1:25, that resistor is dissipating .85W, meaning it is seriously overloaded. It's a dangerous circuit -- never connect stuff directly to the mains.

Please add a short description of what each circuit does so others who don't know what's going on can understand... other than that great video I liked and subbed to you 🔥🔥

Tuyệt vời quá bạn ah, đã bấm đăng ký kênh bạn.

People who do not know electronics would get more use out of the video if you describe what the circuits does.

Without understanding how a LED functions, it isn't obvious how the voltage divider functions to allow the LEDs to be powered from mains.

And neither is it obvious to a beginner how the capacitor charge/discharge is used to control the transistor to create a simple timer light. How the switch can charge the capacitor and that the transisyor turns off when the capacitor has been discharged through the resistor. A beginner would also not understand that R*C affects how long the lamp will be on, and that a bigger resistor makes the discharge slower. Or a larger capacitor means more energy to discharge. So either component can be changed to change the time.

Sir ek muje idea bataiena
Aapana 5 step he vo dhire dhire band ho raha he
Me re esa Bana he ki dhire dhire chalu hona chaie batana sir please

1:32 - This circuit looks similar to the voltage doubler where you replace two diodes with DC capacitors. I got some 30V DC out of a toroidal 11V 4A transformer by using 25V 1000µF capacitors.

1proget එකේ DC ලෛට් 2ක් වගේ පත්තු කරන්න පුළුවන්

At the first one, you can use a 12volt adapter rather than using transformerless adapter that shown in the video. it equals 12v because the led is connected using series and they use 4 meaning 1 led = 3v, 3 x 4 = 12 meaning it can powered by a car battery and also an adapter. I'd recommend you all to use the 12v adapter

ভাইয়া আপনাকে ধন্যবাদ আমি কিছু শিখতে পেরেছি।

"I think I need to calculate the proper series resistor for this LED, " said nobody ever...

[extremPK]

4:24 gate in air, can turn off from any wind blow or air discharge, better use trigger scheme or thyristor scheme or attach gate to + and - by depletion mode transistor or other voltage controlled dynamic resistors like tunnel diodes(will keep gate charge because current bigger on element what have lower voltage)

But he connected diaode from n junction first!! How's that possible?

[faisal]

Good sharing i like your video 👉👍👍👍👍👍👍👍👍

Bagus sekali untuk di buat di rumah y om

[Studs_Studio]

Does number work with an LED and no resistor and connected to battery?
