Bro Resistor input Voltage ko drop kry ga and then output voltage ko 1.5 pe maintain rakhny aur voltage drop sy bachany k liy capacitor zaroori hy .. follow this circuit it will 100% works definitely
@@habbitronics_diy I checked before installing it was 3.7V 2000mAh lithium cell.i thought that voltage divider across the battery might have drained the battery
When we analyze the circuit, the output is different!!! The base voltage is half of the 3.7V, because you use a voltage divider (Base voltage is 1.85V). Then the Emitter voltage should be 0.7V less than the base voltage. That is 1.15V (1.85 - 0.7). But your circuit outputs 1.56V. What am I missing?
not only 7 dear. you can install tp4050 charging module with battery and enjoy lifetime rechargeable wall clock, no tension for replacement of Battery everytime, just charge and use. thanks for watching subscribe for more 😊
Very nicely explained easy to understand for beginners also 👏👍👌 Thanks a bunch
thanks alot for your precious comment ❣️
Zabardast kamal
Thanks
Bhut khoob 🙂
Well done save money 💰 very nice
Thanks
Second time watching your vdo i like your vdo very informative
Thanx 😊
Iis ka diagram deen maan iiss ko pcb par bana chata hoon iis ko kitnay time baad charge kareen iis ko charge karnay ka method bi batain
what a amazing work.. impressed 👍👍💖
thanks
Charging kaise kare. Video Dale sir
dear you can use tp4056 module for charging
Woww amZing work great keep it up
Bahut achi vedio banai hai sirji
it's working well.thaks bro.
Most welcome dear ❤️
Can use 10k resistance?
Waooo so nice ov you my dear brother
Bhai ek video me bus 1k resistor laga ke bana diya hai.. 2 resistor aur capacitor lagana kyu zaroori hai plz bataye..

Good work
Is me battery ko direct charger se bhi connect kr detey ta k bar bar chaging k lye battery niklana na pare
Tp4056 charging module laga dein battery k sath..
Very nice explained
Thank you ❤️
Really Amazing Work bro 👌👌
Single recharge karne pe kitne months chal jayegi?
How long does the battery last until you recharge it again?
ভাই সব ঠিক আছে কিন্তু ব্যাটারী চার্জ দিব কি ভাবে দয়া করে জানাবেন

You can use Tp4056 Module for battery charging. Its very cheap in price
Power bank bms circuit wanted. Please reply...
Dear Power bank circuit main already BMS Hota hy
aab iis ko chargeable banay ka circuit bano jab cell low hoo jay tu adpator se charge kar sakeen
use TP4056 module, available easily in market
Nice project 👍
thanks 😊
6v Solar plate aur diyode laga dijiye thodi thodi charge hoti rahegi hamesha chalegi Ghar ke ander plate lagani hai
4.7k resistor how Any watts sir please reply
you can use any watts of resistor but value must be same
BC547 is the PNP or NPN that you use
it's a bipolar junction, a type of an NPN transistor
Sir is circuit pay 3mm ki led he glow nahi karti itne kam Ampere hay is circuit k
this circuit is suitable only for wall clocks
Bc547 transistor 4.7k resistance 2no 47uf 16 capacity
100mf 50v use good resolt
I too did like this but within a week lithium cell drained off. Can anybody please explain me that why it was like that ?
your battery might be damaged.. drainage depends on MAh and Battery health
@@habbitronics_diy I checked before installing it was 3.7V 2000mAh lithium cell.i thought that voltage divider across the battery might have drained the battery
There is minor consumption across voltage divider not all of your battery. stay blessed stay connected thanks
@@habbitronics_diy thank you very much for your valuable reply and response 🙏
Well... You can add TP4056 module for charging the battery through a mobile charger.
yeah you can
Why not use 1.5v battery
3.7v battery is a rechargeable battery, 1.5v is not a rechargeable, thats why
@@habbitronics_diy I know there are 1.5v rechargeable and for solar. Maybe I can make one with it.
@@eabnamoliben1598 if available then use it

To avoid voltage drop and to maintain output voltage you should use capacitor on output
@@habbitronics_diy therefore the capacitor is used to maintain a steady supply of voltage...
Ac to mobil battery 3,7 se 1,5v wall clock aur recharge hota rah
Dear too many excersize for saving only 7 rs. Ordinary cell costs ony 7 rs per piece, wholesale rate of 10 pcs pack. Just replace n trow old one.
