@@valsalann7856 art. I would say...
Sar mein Ahmedabad se hun aur mujhe bhi Aisa Bluetooth wala karna hai mere pass bhi yahi home theatre hai
@@kunalsolanki8259 video mai jaisa humne dikhaya hai... supply pins se 5v ko check karna hoga....aur input ka koi ek source se connection sahi polarity pe connection karlenese ye modification ye hack internally achese work karega...
Price ?
After replacing the fuse, the system can be started with a series Lamp of 100w. Then ic(s) can be checked for temperature/heat generation and voltage drop to locate the fault.
Yes ... Thank you for pointing out... That method make more sense.... rather then destroying pcb traces...but sometimes it's better to check for fault in no power condition to avoid farther damage...
Sir use bada battry lagasaktihe.
Maximum 12v 12Ah ka lagaya ja sakta hai...usse zayada hoga to charging main dikkat aa saktahai...
Bhai UPS ki battery Lo hone Tak chalana hai kya Karun bhai
Usme 9.5v Tak ka low voltage limit set hai...wo LM339 op amp main kahi pe voltage divider network main resistance ko badalke kuch aur set karna hoga lagtahai...
Is UPS mein preset kis kam ke Hain
Brother i need tips on how to make a Shortwave Antenna
you will find plenty of videos over youtube...else i would try to make one if i have enough time...
Nice information brother, very good video🙏🙏
Diagram?

Gang tune করেছি কিন্তু SW সব চ্যানেল আসছে না। বিশেষ করে শিলং,রাসিয়ান রেডিও, ভয়েস আমেরিকা। শুধু চিনা চ্যানেল ভর্তি।
Tahole IF tuner gulo ke aktu adjust korte hobe...
Charging Ho Raha Hai Magar on Nahin ho raha
Sare ic me input supply voltages check karna hoga...us ke bad on karne walla switching latch circuit check karna hoga...in dono main kahi problem hona chahiye....
Yaar, itna badiyaa information, aur bass 50 likes aur 10 comments?
Sir ap antenna 📡. Jo ferrite Loop. ..4 pin ma Loop antnna. How to connect. ..
Give me electrical circuit
In next video
What a amazing video.. Please keep making more videos
Very good brother, I have seen all your videos today, you have multiple talents and I am very happy especially watching all the videos.
Nice information bro keep it up ...make more video on radio
Apki contact no Kaya hai? Radio station sa dur anay sa bajta Nehi hai.
Resonent antena banayea aur uske sath apne radio ko align kijia... Result accha mile ga
@@rtronicslab1253 How to make this antenna? Can I get it from the market?
How to make Am and Fm strong antena, sir. Give me some tips.
Lots of antena designs are there... the thing will work best for you is use a single wire and put it in a very high place use some reinforcement or something long to elevate the height of the antenna and connect a piece of wire and you can get much more channels out of it and if you want to design specific type of antenna then you have to look it up on the internet and find what frequency you are looking for and find the best suitable antenna for it, generally go with dipole antenna which has medium gain because if are receiving Hai again signals then you may get noise also so it will restart your signal so I try to use medium gain Antennas and try to improve the reception part or the radio part more noise free then you can get much more clean a signal from a very distant source

Sir yah ups sin wev hai ya square wev
Properties iske squares waves ke hain, aur ye 200hz ke uper iske operation frequency hai
#sir isi ups me no load pr 5mint me auto off hone ko kaise band kre, #is ups ko inverter ki tarah upyog kaise kre🙏
Is type ke ups designed nahi hote long power draw ke lea... Uske lea thorda bada mosfet heat shrink laga ke uske je timing circuit ko continues pulse de ke uske ratings ke 40-50 Percentage load de kar 6 to 7hrs tak inverter ki tarha use kar sakte hain... Per transforer heat hota hai... Power loss thoda zayada hota hai.... Kar sakte hai... Par thord tricky hai... Board to board solution vary kare ga... Isme age ki ak video planing vi hai... Wait karo...kuch to jugad karunga...
#ok sir🙏
Nicely explained 🎉🎉❤
Ic kit ka wiring karke dikhaye
Mere ups band hoo jaa raha hai 1 minet ke bad
Battery backup nai de raha... Wo pahele check karna padega
Bhai Aisa ups mere pass bhi hai but usse bypass karna hai taki 5 minute me automatic band na ho
Sem problem
Kya tujhe solution mila
Nahi
Me abhi ups khol ke baheta hu or mujhe kuchha samajha nahi aa raha hai kya kru R 19 register bhi nikal diya hai fir bhi ups off ho ja raha hai
Battery voltage continious check karo off hone tak... 10v ke niche uter ta hai... To battery karab hai... Aur clamp meter hai to ac me ampere check karo zayada le rahahai ki nahi...
