all videos is good and thank you very much you put all electrical circuit diagram in PDF

[@ahmadrasyid3366]

Ferry good my from Indonesian

[@theworldoffannyvideos9505]

gooood sir

[@sansislivehere]

Great 1 i also make this 1 thanks for making video on this

[@alexandrossotiropoulos5621]

it is nice for a bicycle!

[@ogunkoyahakeemabiodun7688]

well-done, have been following dis your practical u have been doing a wonderful work my challenging is dat I did not know the value of d components u are using & d number of d transistor & d type wether is Bjet or MOSFET transistor pls I shall be great ful, if u can list d components value thanks.

[@InnovationKH]

For component of battery charger here: - Transistor NPN : C2383 - 2 Resistance: 100 ohm and 330 ohm - Diode Zenor: 3.7V - Diode: 1N4007 - 1 Phone battery 3.7V -1 LED light bulb 12V Thanks you for watching.

[@kedarprabhudessai]

hi nice build 👍have u coonected those leds in parallel? and what type of the charging ckt it is? can u safely charge li ion cell withbit safely? will u provide schmetics plsss

[@InnovationKH]

Yes sure i have connected those leds in parallel and circuit for charging battery. it is not safety for battery because it is not automatic cut off circuit when battery full charged but we can charge 1 hour it is OK. Thanks for watching

Hla boa noite quantas horas é a durabilidade da bateria nesse circuito?

[@ashoksah410]

owesome idea

[@necoisidois7570]

Helal olsun dostum ! Tebrik ederim iyi iş çıkarmışsın..

good idea but no specification for the circuit the resisters and capacitor??? Awesome work. 😎😎😎😎

[@manojsaha5732]

PEOPLE HAVE

[@danielchoi2252]

If the battery is fully charged, how does the circuit flow? Is there a way to mark the LED as a checkmark when it is fully buffered? I have tried the full synthesis of the LED, but I do not know if it is correct, assuming 3.5 ohms and 80 mA flows in one LED If one of the three LEDs connected in parallel fails, I wonder if the other two LEDs will increase the current and damage the LED. What is the best way to configure the circuit so it will not break?

[@bhanuharesh3100]

Agar aapke pass led hai aur uspe likha nahi kitne vault ki hai to kaise pata karenge ki kitne vault pe jalega ?

[@valtersouza7446]

Nice

[@TheDaltonic]

I hope you can help me I have a LED strip ws2812b of 5v factory if I connect it with a 3.7v battery would work the led strip or would have you do something else? Thank you

[@tunahankaratay1523]

3,7v will do so but darker light. If you want both protection, charge and boosting to 5v, then use one of those cheap powerbank modules or simply use a powerbank.

[@programer0713]

Good idea, good work, awesome video, but the quality of the "case" is not the best. why dont use a drill?? melting plastic is never a good idea. but i still liked the video :)

[@InnovationKH]

Thanks you for comment and watching

[@SHERIFDEAN]

as you said he gave the idea, and maybe he don't have a drill and i think he don't understand English after i read his polite reply i think he just used what is available in his hand so he just melt it, if you can make it better it will be nice to see your video, be creative.

[@ogunkoyahakeemabiodun7688]

sorry I don't know if u can make d circuit diagram or S manual available thanks.

[@adnandiab536]

What maxVoltage of Emmiter and diod in output Thanks very much

[@InnovationKH]

maxVoltage of Emmiter is 5.5V and diod in output is 3.9V. Thanks for watching

[@adnandiab536]

Innovation KH excuse me sir here base voltage is 3.7 v constant by zener so Emmiter voltage must be less than 3.7 about 0.7 v and output less fw diod voltage Is that right Thanks

[@omkumarsarkar9624]

Sir I want to convert 220v led bulb into 3v rechargeable bulb please make a vedio

[@djalmaamaro2574]

ola boa noite o amigo ai pode me dizer de quanto é esses resistores dos ledes ? por quê nu vídeo estar um pouco embasado e não ta dando pra ver.

[@PrasetyoMuhammadDwiBiology]

btw schematic is on 1:15 so if i have one powerbank, it is just simple as rewiring LEDs with one limiting resistor to three LEDs right?? then i dont have to think about the charger :D

[@calicheartegas659]

muy pero muy bueno

[@InnovationKH]

Thanks you so much

[@julianodias9269]

Where is circuit diagram??

[@InnovationKH]

This video no circuit. thanks for watching

[@aigleblanc3966]

Toutes vos vidéo son trucer (fix ) oki yes

[@miteshdhanani]

Too fast in showing instead of making the circuit we can use the circuit which we r getting ready

LED karap lights kase Thaki kare saka

[@mohamedshatla]

How long this led works

[@InnovationKH]

Long time, Thanks for watching

[@diymodifymodify1132]

can u make a charger for 9V battery

[@InnovationKH]

Let's me try for next video, thanks for watching

[@AnilKumar-ll5tn]

Good

[@hunvannpanha6500]

B how many led ?

[@gustavoburgos7140]

amigo saludos. por favor en español pregunto que son esos cortes que hace en la placa buen video pero el problema por favor con blabla y blabla para poder entender gracias y chao

[@mohamedshatla]

Can you send circuit diagram for me please

[@InnovationKH]

Please see in videos. Thanks

[@raLdzkie23]

Indicate the circuit diagram and you use

[@AjayKumar-bg2dw]

Parts ka na. Batao

[@rameshzyate9314]

apaka mobile no.do sir

[@yasirtanveer1574]

send me circut diagram

[@InnovationKH]

Please see in video, thanks for watching
