Dada darun hoyse circuit ta ami ato din wait korsilam ai circuit er jonno
Clear circuit is very much needed to make it. Your explanation is very fine but the drawing don't give clear picture. Please provide the circuit re-drawn.
Hi Free Circuit Lab,
Very good Tutorial. Appricate your efforts.
Excellent knowledge brother
I m also a electronic enthusiasts and just love how much knowledge u possess..
You are really ginious. I respect your knoledge.
Sir akdom easy rc reciever and transmitter bonayie 4channel ka
Amazing project
Very Very Well Explained 👏🏻🌹
Ye video mera bahut kam aaya thank you bhai
Good tiching karte hai 👌👍👌👌👍👍👌👌👌
You are genious and best profeshional engenier.
Amazing idea ♥️
Gajab admi ho yaar ap
Very good expand
Thank you
Great bro!
Short circuit protection per bhi video bnaao lab power supply ke liye!
you have great knowledge sir
Good information bro.👌👌👌
Very good explain.
Very nice bro
All ready done but fir bhi dekhne me maza aya
Excellent explanation specially of Op-Amp and Comparator functions. How and where did you connect the Green LED for Voltage control and the Red LED for Current control?
Next video:
Mind blowing 👍
Very good information
Nice explanation
Sir bhot a6a video tha
Sir tl494 IC ka use kar ka variable power supply baniya agar ho saka to or asa hi current control ka sath
Maine is ic ka smps me karke dikhaya tha
Thanks bhai
Anazing bhai
genius Bhai 🙏🙏
Gurudev...!!! 🙏🙏🙏
Agli video men shout out dena mujhe thank you for the video
Wow such a amazing
I needed this exact thing just a week ago.
Also, my cheap multimeter don't have protection so they fry very soon. I am planning to buy expensive protected one.
I narrowed to DT17n and ZT300AB. Which one should I buy. (Both from babaocatools)
DT17n and ZT300AB both are cheap-o meter without any protection
Kiya boost converter (xl6009e1) wale kay liye bhi current control ka yehi circuit ho ga??
Suvho noboborsho 🙏
Subha NabaBarsha
Ek shunt resistor or ek npn transistor ke sath bhi bana skate hai but adjustable nhi hoga
👌👌👌👍
sirjii ye sab kya lm2577 jo step up converter hota hai uspar kaaj karega? pin4 ke badle pin2 me connect karne par?? pin2 lm2577 ka feedback pin hota hai lekin lm358 node ke par input se power de raha hai apka circuit lekin step up module meh wohi node par kya output se power dena parega??
please reply sir
Can we use the same trick in the buck boost converter..??
How to add charge control pot to this circuit, like 3pot lm2596 module.
Can u please show us the ripple of both at oscilloscope...its very important ..since i have to complete my project..but i don't have a oscilloscope
These converters have around 300mV ripple
@@FreeCircuitLab and what about the lm317t
@@FreeCircuitLab can i use this lm2596 for sensitive application like thermocouple etc.. and is there any way to Remove this ripple
@@parashmanikalita8893 if you do not need high current, ripple removal is very easy. Connect a low series Resistance of 1 to 10 Ohm and a capacitor of 100uF and 100nf in parallel. Done.
Sir wireing ke upar detail video banayeye
Kya hum isi op amp error signal ko smps ka tl431 ka reference pin ko dene se amp limiting Kam hoga?
Yes bro
@@FreeCircuitLab thank u ,
Yahi toh chahiye tha 😘
Ap ne ak video banaya tha cpu ki powar suplay ATX ka tha us me ic 949 thi to or dusri ic ho to kese bana te he us ke upar video banaye. Hs8108 ya 7520./2921/2005/ 6105 yesi sab ic hoti he to hm kese banaye
Sir please add kariye short circuit protection feature is lm2596 module me I am your big supporting guy 😎
Is this applicable to MT3608 ?
Isme voltage & ampare meter laga den to jabardast ho jaega ,,, is regulator device me 4 chand lag jayenge ,,,,,
Sir kya ya tric SMPS ma bhe Kam kragi
Sir please make Bass treble circuit
Op ho sir app
How to use this lm2958 with high current. Like 10amp
Not possible
step doun me input kitne amp de sakte hai
Next video step up module please😫🙏🙏💓
Ye bahut kam ka video hai lithium battery charging ke liye.
Bahut bar video dekhne ke baad samjh me aaya ye wala
Kuch esa karo ki ye amp jada de step up vala me ok 775 mother chalana hai
Suppose kariye hamare pass kuch 3.7 volt lithium battery hai ok like kisi bt speaker ki 18650 ya phone ki jime bms nahi hai then hm us battery kitne % charge hai kaise pata laga sakte hain pura accurate bhi nahi chaiye bas lagbhag ki 20% hai ya 40 ya 50 ya 80 ya 90+ % and easy method hona chahiye jo ki easily banaya ja sake agar kuch components chahiye wo ghar k purane electronic appliances se nikal k banaya ja sake I hope ap samajh gye hoge mai kya kehna chahta hoon..
Banaunga.
@@FreeCircuitLab dhanyawad..but jaise maine bola hai as it is banne ki kosis kariyega
Mera voltage drop ho ja raha jab load connect karta hoon toh .
2.2 volt from 7 volt
Input 14.6 volt...
How to solve ..
bhai, awesome video, Just one Doubt.
maan lo maine buck convertor me ye banaya (BUCK CONVertor)
5V input rakha...
1A current limit kya...
ab...
1. jab 1ohm ka load lagaya... to 1A flow hogi, mean voltage across load = 1V
2. jab 3ohm ka load lagaya... to 1A flow hogi, mean voltage across load = 3V
3. jab 10ohm ka load lagaya... to 1A flow hogi, mean voltage across load = 10V
4. jab 25ohm ka load lagaya... to 1A flow hogi, mean voltage across load = 25V
Above me se kaun se points correct hai...
Agar all of them... to buck convertor 5v se 25V bhi bana sakta hai kya???(is modification se...)
5v input me output kabhi bhi 5 se upar nhi hogi. To 5ohm ke niche hoga to constant current dega, warna constant voltage
@@FreeCircuitLab ok
With only this modification,
0.5ohm resistance के साथ क्या, voltage 0.5V होगा???
(as unmodified buck converter has a lower limit about 1.2V...)
Similarly, a modified boost convertor, can it by pass its 40v upper limit?
Sir please jwab dejeay ga ya video bnaeay ga...yeh btain k ampare kasy bnaiy ja sakty han ampare k liy kya thing mean component zarori hoty han?...please sir give the ans..
Ampere automatic banta hai. Koi resistance ke across me Voltage dene se
@@FreeCircuitLab sir is k mutaliq koi detale video bnain....just resister k throw ampare bnta hy and resister ki value and watt is me koi kirdar ada krti hy ya ni..please video bna den is peh. .thanks.
Sir mera pas sunshine ka DT9205:E multimeter hai use ko me 10amper dc mode set karke probs 10A aur common me lagake 12v 2.5ah ka battery ka short circuit current measure kiya first yek do second keliya meter 2 amp 3amps dikaya fir achnak se galath reading dikhaya me doseree bar meter ko dc motor aur led 12v buld ko load lagake chek kiya bar load tho wark kar raha fir wrong value dikaraha hai mai meter ko open karko dekha shunt wire ahhai hai please help me sir how repair my multi meter 10ampdc section meter mother board bahut confusion hai iske bare me batow how to solve it: thanks sir
First thing, aap galat tarike se check kiye the. Battery ki ampere naam ka koi chiz hi nhi hote hai. Jo likha rehta hai wo amp-hour hai, amp nhi.
Isme shunt wire damage hua hoga. Usko thik kro.
Sir actually ye mera question tha shunt wire tho perfect haii . Lekin use mai current sence resistor muje patha nahi iske bare me online me koja lekin circuit diagram nahi mela .muze lagerahai current sence resistor ok but wrong value sir ap batow kyese repair kare aur battery ka pshort circuit current kyese measure kare. Meter ko repair karnekeliya 10a dc section ko repair karnekaliya konsa components ko chek karnapadega .shunt wire soldring connections are perfect
One concept is not understand
Jab potentiometer ko 3voltage me set karenge to shunt resistance me 60 mv Banega to amplifier ke positive me 3 voltage se jayaga banega Jesse signal high ho jayega high me kitna voltage aayega jo feedback pin me jayaga
Sir ya stp up over hitting horahe kamnahi karta
Me bana ke dekh ta hu Mera circuit Kam karta he kya ❤
for a buck convertor modified in this way, with 5V Input,
1. jab 1ohm ka load lagaya... to 1A flow hogi, mean voltage across load = 1V
2. jab 3ohm ka load lagaya... to 1A flow hogi, mean voltage across load = 3V
3. jab 10ohm ka load lagaya... to 1A flow hogi, mean voltage across load = 10V
4. jab 25ohm ka load lagaya... to 1A flow hogi, mean voltage across load = 25V
Above me se kaun se points correct hai...
(duplicate as, short version of another comment, )
Sir. Mene Bohat sar khapaa lia hai mujy Ampere Cantrol karny ki theorie samjh nahi aa rahi please Help me another way. Please 🙏
Video firse dekho
Cc mode me vo red led kese jal ra he..use kaha connect kia?🤔
Lm358 ki pin7 me
How to step up Ampere ? ?
This module actually does this. It takes low amp, high voltage and gives higher amp, low voltage
Bhai mera ye chal nahi rahai hai kaise theek karu
Ise 12 volt ka motor ni Chalta 😭 bs led chalta hai
Step up vala ki bol rha hu
2.8 amps ke upper nahi le Gaye hai
দাদা, LED দুটো কিভাবে লোডের সাথে জ্বলে উঠে বুঝলাম না।

My friend's didn't like it... My love it is
PNP TR AK US KARKE BHI YESE BANA SAKTE HE. DABA TV ME STR ME PNP TR US KARKE BANA HOTA THA. OVAR LOD ME BAND KAR DETA THA.
Hmm. Wo bhi bana shakte h. But itna easily adjustable nhi hoga
