in this video {909} Delay-Timer circuit i discussed a time delay circuit using resistor and capacitor, we can use "power on delay timer circuit or power off delay timer circuit" it provides a specific time to turn on any circuit and after specific time it will disconnect power from that circuit. and it can be used to provide a delay time to power on circuit,

*CORRECTION, PLEASE, at timeline **7:41** i said 2.72 microseconds, it is 2.72 seconds.*

Great for a "soft start" circuit. I was just thinking about this yesterday. 2N2222 and 3904 transistors work great too. Thanks and have a great weekend!

You are the best, Thank you. This is perfect for my in rush current problem. Part 1 everything on, Part 2 big capacitor charge. Next I fire solenoid, and repeat. Have you done a video on back EMF or snubbers? It turns out that my pinball coil, (4 ohm), pulls in well at 30 volts, but when I turn it off my driving transistor gets several thousand volts and explodes. I am learning, Thank You again, you are great, from Bill.

Very interesting. As I know very little, I have used always 555 ICs to do simple timing of relays in automotive, but this is a more simple and compact approach. I will try it.
Thanks Haseeb, as always your lessons are a true gift.

السلام عليكم الله يعطيك العافية عند المشكلة التالية تنين موسفيت لازم يشتغلو بلتناوب اشارة التشغيل رح تكون pwm بس معم بقدر اعمل ازاحة بإحدى الاشارتين كرمال يشتغلو بلتناوب والله يجزيك الخير

nice video sr
I had a question, I bought a smps 12v 10A and it doesn't have any pwm ic like TLC494 and also no adjustable voltage trimmer, that means voltage adjust is not possible in this smps ??

INSTEAD OF USING A MICROSWITCH IN PARALLEL TO DISCHARGE THE TIME CAPACITOR. HOW CAN WE SELECT THE RIGHT BLEEDER RESISTOR TO PERFORM THAT FUNCTION. WHAT IS THE CRITERION TO SELECT A GOOD BLEEDER RESISTOR IN DELAY TIMER CIRCUITS.

Sir how to calculate delay time for this circuit .

I want to understand why you connect the zener diode in that way instead of normal parallel connection kindly explain in details different ways we can connect zener diode.
Thanks

You don't need a Zener diode - just Resistors, a Cap and a Transistor
