شکریہ جناب🇵🇰❤🎉

[@Vidya1939]

Very nice . Basically it's a oscillator circuit and v useful TkQ sir Ji

[@singhpreet3066]

बहुत बढ़िया जानकारी, sir ye transistor न मिले तो कोई दूसरा?और डायोड 360की जगह 4007 लगा सकते है?

[@RameshPal-cd4cs]

Really interesting. Bhai ayi sa aur ek Banao jise ham 50 rgb led jhalor check kar sekta hai.😂❤

[@akosmsong9714]

Nice information bhai, Kya dusra transistor use kar sakte hai

[@SNHooda]

बहुत बढिया, सर। इसको 125 वोल्टैज तक ले जाएं

[@FaizTech466]

Good

[@anilkumargoel307]

Dear Sir. Circuit is very good and very useful. If I increase the input voltage from 3.7 volt to 6 volt the output voltage will increase or not. For this any changes in the circuit to be made or any change in component. Please do reply I am waiting.

[@anilkumargoel307]

Sir. Curcuit is very good. How we can increase output voltage upto 100v. If we give 6 volt batt. Input instead of 3.9v, out put Volt can be increased upto 100v

[@m.d.ali._786]

Very interesting knowledgable post

[@sarfarajansaari6548]

Is taranjistar ke na milne par konsa taranjistar lagaye

[@dhyanandastrology8073]

Any NPN transistor use kar sakte hain

[@anilkumargoel307]

Please fix saparate digital Volt meter and charging circuit for charging the 3.9v battery. Instead of battery 3.9v can we give 6volt from step-down transformer ie 220v to 606 outout

aap ne kaha 1000uf 80v par aap laga rah 100uf 80v kon sa shai h sir

[@rosyspecialkitchen]

9volt ki battary se nhi Kam hoga?

[@swarupnandi3285]

73 Volt se ek 3 volt led kharab bhi to ho sakta hai

[@vijayyadav-co8np]

😢 sari circuit se emergency light Jala sakte hain

सर्किट 73 वोल्ट दिखाता है फिर 3वोल्ट की एल ई डी कैसे ग्लो होगी।कृपया बताएं

[@DevendraSingh-de1eo]

1k की रजिस्टेंस के कारण volt एल ई डी की क्षमता अनुसार स्वत: एडजेस्ट हो जायेगा।
