आपका सिखाने का तरीका बहुत ही अच्छा है।
👍👍👍
💖💝
Wow very helpful
Thanks Bhai 😊
Super
Good🎉
On top emergency light ka changing circuit repair video
12 volt me kam karegi
Nice 👍
Mere paas onlite model no 789 ka torch hai chalu karne ke bad band hota hai us circuit me program ic hai uska number nahi diya hai
12 v ka srkit banao
Sar koi new video bnao iske bare me plz
resistance tho sort hojay ga 🤔
Kiu short hoga bro acche se video ko dekho ap , agar thumbnail dekh kr bol rahe ho to
Battery charge hota hai jab light off hota hai?
Can we add bms to circuit in stead of micro USB connecter and we're should it be connected in circuit urgent
How to connect A bms to this circuit
Isi me bhai button kaha lagaye k light rehne par bhi on ya off manually kar pai.. Batao bhai
Bro ap light ki positive wire pe switch lagado
Can i 9v use battery
Why bro ?
Battery cut off nahi hoga toh khrab ho jayega
Sar is me ek dikkat a raha hai ...
Ham direct battery se chalate Hai to light ka Roshani adhik hota Hai
Aur ham transistor se chalate Hai To Roshani kam hota Hai voltage check karta hun to sem a raha hai light jalane per voltage gir ja raha hai 😂
1k register knu lagaya
I have led rechargeable light
I want to make it the AC rechargeable light make a while I put phone charger want be cut off light will be on in the same time
Bhai battery recharge hogi ya nahi?
Hogi
Kaam nahi kar raha. Hai
Hit sink na lagana sa hoga kia
Ha bhai hoga ap yeah transistor utna heat nahi hota hai
Aur BD140 ka Bina D2470 sa hoga kia
Nahi bro yeah NPN transistor hai
1 k ca rajistance sa electric pass hota ha kia
@@sndrawing4853 ha bhai 1k resistance se electric jata hai or transistor ko on kardeta hai
Diode connection lagata sahi but bolta jhuth
Bhaiya mere ko college me microproject mila tha ye maine banaya bhi lekin light nahi lag raha😢
But why ?
Pata nahi maine kiya tha sab kuch apka video bhi acche se dekha 4-5 bar

Charge ful hone par. Off ho. Cut.
