It was working. But quickly automatic discharge battery any solution?

[@irshadhusain407]

Sir bd140 transistor heet sink ke saath laga rahe phir bhi heet ho ke kharab ho raha h

[@SUNILKUMAR-qs7rt]

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 😂

[@reinaldogomez380]

👍👍👍

[@letsdoexperiments6552]

Kaam nahi kar raha. Hai

[@VIMALKUMAR-oj2dd]

On top emergency light ka changing circuit repair video

[@Sanatan_dharm._krishn]

12 volt me kam karegi

[@oldmemories-we4mx]

Diode connection lagata sahi but bolta jhuth

[@rajendragaur7586]

220 AC लाईट पर चलना चाहिए

[@SUNILKUMAR-qs7rt]

Sar koi new video bnao iske bare me plz

[@rasel_s7]

resistance tho sort hojay ga 🤔

[@skr_electronics_lab]

Kiu short hoga bro acche se video ko dekho ap , agar thumbnail dekh kr bol rahe ho to

[@sadashivkale6860]

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

[@shaikhabdullah1846]

Isi me bhai button kaha lagaye k light rehne par bhi on ya off manually kar pai.. Batao bhai

[@skr_electronics_lab]

Bro ap light ki positive wire pe switch lagado

[@sanjaykhurana3400]

Charge ful hone par. Off ho. Cut.

[@pradeepchoudhari2217]

आपका सिखाने का तरीका बहुत ही अच्छा है।

[@successtours7023]

I have led rechargeable light

[@successtours7023]

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

[@hiteshdhodi1167]

Battery cut off nahi hoga toh khrab ho jayega

[@ofybc5560]

Battery charge hota hai jab light off hota hai?

[@roshanirathod6537]

Bhaiya mere ko college me microproject mila tha ye maine banaya bhi lekin light nahi lag raha😢

[@skr_electronics_lab]

But why ?

[@roshanirathod6537]

Pata nahi maine kiya tha sab kuch apka video bhi acche se dekha 4-5 bar

[@skr_electronics_lab]

@@roshanirathod6537 message me in Instagram

[@apsarpatanpatan513]

Can i 9v use battery

[@skr_electronics_lab]

Why bro ?

[@MahbboobkhanMahboob]

12 v ka srkit banao

[@roopchanderradhakrishna2858]

Can we add bms to circuit in stead of micro USB connecter and we're should it be connected in circuit urgent

[@roopchanderradhakrishna2858]

How to connect A bms to this circuit

[@SBRtechnical]

Wow very helpful

[@skr_electronics_lab]

Thanks Bhai 😊

[@dilipmaity376]

1k register knu lagaya

[@gaminipattiyage9921]

Good🎉

[@djmuslimbaliapur6364]

Super

[@dineshnaik2785]

Bhai battery recharge hogi ya nahi?

[@skr_electronics_lab]

Hogi

[@sndrawing4853]

Hit sink na lagana sa hoga kia

[@skr_electronics_lab]

Ha bhai hoga ap yeah transistor utna heat nahi hota hai

[@sndrawing4853]

Aur BD140 ka Bina D2470 sa hoga kia

[@skr_electronics_lab]

Nahi bro yeah NPN transistor hai

[@sndrawing4853]

1 k ca rajistance sa electric pass hota ha kia

[@skr_electronics_lab]

@@sndrawing4853 ha bhai 1k resistance se electric jata hai or transistor ko on kardeta hai

[@vlogwithskr9554]

Nice 👍
