it's good to see how Arduino and simple program can handle high frequency inverter ,but risk is high if you are running without adding mosfet driver ic like ir4427 or selecting wrong mosfet .feedback control system is needed for auto adjust the output voltage , i will do it in future video. thanks

you can use petrol (gasoline) or wd40 . after cleaning process dry it well other wise it react with compressor oil .

Thanks

Thank you 😊

Thank you

Sorry bro ,this is the first part . As a normal technician with limited equipment how to do the repair and restoration process through step by step video that's my intention . AC technician don't repair compressor ,they just throw it to scrap. In this video I am repairing a fully jammed one ,so i done the repair through this video ,now what's left is welding, changing dryer filter and painting . I am sorry I can't make all the process in one video.

@@FEMtech4you good job bro.......😊👍

You too sir, for watching my video

Thanks

i will appreciate you about the argument of safety concerns . if you want to charge battery safely ,then you need to provide the exact charging voltage ,for example 3.7 v battery need 4.2 volt ,3.2 v lfpo battery need 3.7 volt for charging ,internal resistance is low when the battery is fully drained , at that time charging current is high ,but it doesn't mean it crossing the limit ,today battery's are support fast charging like 0.5C to 20C .3.2 v 6000mah battery support 1C continues charging that means 6A charging current , li-polymer is also support fast charging up to 3C . i am using this unit for charging different battery's , at this time i didn't face such a tragical situation, but still safety is important . please provide the correct charging voltage provided by the battery manufacturer . thank you

If your providing correct charging current then there is no battery heating up issue . consider 7000mah ups battery ,its charging current is 1000mah so how about 100mah battery ,how much charging current that we can provide 7mah or 10mah . how about 50mah battery ? . i am using these kind of batters for TV & AC remote control , multi meter and some small electronic units . so i am facing a charging issue , my batters are dyeing because of high charging current . so this is my solution , i what to share it with prof .THANKS FOR SHARING YOUR SUGGESTION.

Forgive me this time ,next time i will do my level best , and about the 'charging current variation ' tp 4056 is adjusting its charging current through its programming resister.

After cleaning it just weld the top and bottom cover and paint it , that it . Video become large that why I avoid the process. People are not interested to watch long videos in a small channel.sorry for the missing part of the video.

felicitaciones !! muy interesante.

sorry ; i didn't mean to do that , my laptop is not so powerful to edit larger files ,so some time i miss the cutting part of the video .

no , bro it's a working inverter. but LFPO Battery 3.2v 6000mah will not last for 5000 cycle , 100/3.2v=31.25 Amp is require to run this inverter .

Circuit diagram dena please 🙏🙏 22:17

There's a 4 leg ic for drive two coils , ic is wired like this : pin 1 , 4 is (-) (+) ; pin 2&3 is the pwm output , we can use this to drive any mosfit . Don't remove the ic from fan , also fan must run with minimum voltage of 5v .l made 3 videos that you can easily understand the wiring. goodluck 👍

Bro I know this,I asked for wire diameter for led and charger that formula

this is just an experiment

Thanks ✌️

this is just an experiment

There is nothing to fake. It is a simple inverter any one can make this one. Cpu fan driving Ic is used to drive this mosfit. If you are a technician you know well about this. Then why did you mention it as fake. Can you explain where is fake side of this inverter
