That was interesting, thank you.
Creative Techos, can you please make a video of LDR project 1 with delay shutoff using a 50k potentiometer to adjust time up to 1 minute delay?
Helpful. Thanks
Would be nice to have voltage shown on the schematic diagrams
Can we use Bt 136 in place of 2P4M...??
time 3:50 battery auto cut off schematic diagram...... it is mentioned left side LED Green is CHRG... It must be FULL... and right side LED Red is FLL... It must be Charge.... As well this scheme will do relay flickering while the battery voltage in the mid ratting.
Never mind the red/green, what about that 2.2k resistor to keep the LEDs from seeing 14V that’s not in the schematic. Tell you what, if these guys are this sloppy I don’t think I’ll be hooking anything up to line voltage ;-)
he just copies crappy circuits he found on YT
he does not actually know anything
even the construction sucks
You show the schematic diagram too fast , could you show them at least 5 seconds please and thank you😊
Try pausing 🤪
The pause button is your friend. 👍
Watch it in slow speed or take a screen shot
Yeah it’s “inconveniently” quick. Even “precise seeking” (on iPad, anyway) misses it.
Kkkkk
Great content my brother
@3:50 is this circuit based on CC CV protocol?
Hello, for the proyect 1, can I use 120v AC? With a bt136? Thanks
Thx, interesting. I think the first schematic (1:51) is wrong, the LDR and 220K should be connected to the front of the thyristor / pin 4 of the rectifier, and not to pin 1 of the rectifier. Cheers!
Yeah, the way it’s drawn it’s a voltage divider from - to - lol. Nice use of bridge, haven’t seen it used as a series device before
Second schematic also wrong!😉
@@mr_tom_1_0 It was once a common way to use thyristors to switch both sides of an AC cycle before triacs became commonly available. This circuit could be built with a triac instead and then it wouldn't need the bridge as the rest of the components are non polarised.
@@Fedor___1 si esta mal el transistor no se puede conectar a la entrada sino al la salida para que testee la tension de salida cuando es la tension alta se corta
4s QE da Streetnnnnnññnnnnnn jj😢😢😢😅@@mr_tom_1_0
استاذ بالنسبة للمشروع الأول ألا تتأثر مقاومة LDr بقوة الضوء الصادر عن المصباح وكم يجب أن تكون بعيدة عنه وبالنسبة للمشروع الثاني ما هو الأمبير الذي يمكن أن تمرره الدارة للبطارية وشكرا
You forgot two resistors in the schematic circuit diagram for second project
Is it 110v or 220 v?
interesting slightly dangerous working with 220V.....how much dc is pushed out on that last project
i think the circuit diagram there would help better
Please watch video without skipping, i have already shown circuit diagram of each project 😄

You are legend ❤❤
I think that the word "chrg" and "full" shoud be replace aech other on charg diagram.
I agree. Also there the LEDs have no current limit resistors shown in the schematic so they will burn out instantly.
My two cents. For the circuit to work, J15 should be connected to a current controlled voltage source. When the battery voltage is low, the current will be maximal and the voltage on J15 will also low. Low enough the keep the transistor driven via the base connected to the potentiometer in its of position and the relais in the off state. The battery will be charged via contact pin 3. When the battery voltage rises, the voltage on J15 will also increase. At a certain moment the voltage on the base of the transistor will be high enough to activate the relais. The voltage on J15 will now switch via pin 4 to the other led. This will lower the current far under the maximum value, so the current controlled voltage source will now run in voltage controlled mode and drive J15 with its preset voltage. And yes both LEDs do need a series resistor for protection. When the current controlled voltage source on J15 is disconnected and reconnected again, the relais is activated directly again as there is no load current needed. In the current diagram, the relais is drawn in its activated state. So yes, the words chrg and full need to be swapped. The 1N5408 diode is to prevent discharging of the battery via the led when the relais is activated.
Thank you and congratulations for the highest quality of work and images ! 👋
Get rid of that awful music, terribly disturbing and annoying.
Video content is good otherwise.
263v to 230v convert pure Ghar lea circuit bana ye sir
Excelente
This is not for beginners! Do not fiddle with mains as shown here if you do not know what you are doing.
Here in the US we use 120v what would be the change in the design, if any? Great video!
Diagram में 1M resistor सही जगह पर जुड़ा हुआ नहीं है।
Very nice circuits
Thanx
where are the resistors bro? schema error.(3:50)
To The project man
First let them take the schematic diagram
Give some time to draw the sketch
Then you can do the work
So it will be easy for them
I don't need to watch 10 min of content to find out what it does and that it,s useless to me.
Thanks
What 7:11💥?
How much watt does the project 3 (12v adapter) produce?
Improvement suggestion: the video with text has the text visible for short periods. I dislike having to stop the video, back up, find the text, read it and start the video. Not all of us have 20 year old vision. Make the duration of the text longer. This will help viewer satisfaction.
The components specifications would be better to show them so that we can buy and try do ourself.Yes you show purposely the specifications too fast as mentioned in the comments by viewers.
What is the purpose of this gadget
There is no explanation
Super
How are you ahmad logs
Para el último proyecto. Cómo sería para 120 voltios
No clearence components name and number
🎉
Not enough time to see schematic
Pause the video, then!
Because they're wrong!😉
