Thank you.. Yes I missed some details

I will

​@@Inventor_AW cut the music please

Great to see the music creator credited in any case!

thanks , you're right

Krrrrr

thanks and Sorry about the music

People are WAY too paranoid about magnets near computers. That little craft store magnet barely has any strength. Remember that every spinning hard drive already has high power neodymium magnets inside it for positioning the heads. They don't interfere with the data on the drives, and they are inside the same case as the spinning discs, sometimes less than an inch away from the data. While it definitely IS possible for magnets to destroy data on magnetic storage, it's actually a lot harder than most people think. I have taken 5.25" floppy discs and rubbed them all over an 80 ounce subwoofer magnet, then left it on the magnet over night, and the next day every single bit of data on it was still perfectly readable with no errors. I'm not saying that would be the result EVERY time, and I'm not suggesting anyone try it, especially if your data is important, but there's no need to be afraid of a tiny magnet like that one near your USB port. It's not going to damage anything at all.

@@eric_d you may be correct, but that wasn’t my only reason.

thank you

No, you can not. Do one of the test circuits from the 4558's datasheet.

thanks

Thank you for the tips.. Regarding testing the IC with the power connected.. I did this in order to avoid the word "fake" but I got it anyway

@@Inventor_AW and it's called a dip socket, not an ic base

I agree with you 😊

Thanks for your Kind input, the internet can be the most wonderful path of learning and discovery, a journey with no end in sight 😎

thanks , I will

@@Inventor_AW AWESOME, can't wait,,,🙂

both of them are correct , look at the simulation ukposts.info/have/v-deo/a2OCd5mIpX-nx2g.html

I hadn't seen it! Thank you very much!

@@user-qw3is9sf7x you're very welcome

хорошая работа .. спасибо

@@Inventor_AW Спасибо За Ваш ответ!Жду подписки!

is it PCB company ?

Sorry I meant mustool. Those handtek ones are kind of pricy. I'd get a regular oscilloscope for that.

sorry

sorry , i have no idea , You can check for yourself by contacting them

thank you

thank you

more of a tip situation, super small with an angled or inset edge, get solder on it and touch, its like pick and place. I figured that out working on super small electronics with tons of components

thank you flux buying link : www.alibaba.com/product-detail/BST-559A-50g-Lead-free-Insulating_1600391519000.html?spm=a2700.galleryofferlist.0.0.727f3cedIH3lkU solder buying link : www.alibaba.com/product-detail/Solder-Tin-Soldering-Wire-Rosin-Activated_1600532780361.html?spm=a2700.galleryofferlist.normal_offer.d_image.5da84c71u1RoGT&s=p

sorry?

素敵なお言葉ありがとうございます

Dude, are you serious? He is using the same buzzer for both cases.

sorry , you are wrong

You are wrong. YES it depends on the chip being OK. In this case you should use an active buzzer, meaning one tha has a built in oscillator that beeps arround 2700 Hz. If the chip is OK, then THE CHIP will output a square wave arround 2 or 3 Hz. So, you will hear a 2700 Hz signal on and off at a 2 Hz rate. If the chip is bad, depending on the failure, you may hear a continuous tone, or not tone at all.

thanks bro

maybe

@@Inventor_AW I'd think it would make it easier to insert & remove the chip and harder to break off the cap.

thank you

there are many don't like it

@@Inventor_AW I noticed. I thought lets be less negative. It was a happy tune. My daughter of 18 months also liked the song. I liked the project, so both enjoyed the videos.

​@@MrSpacelyy Thank you for being kind .. kisses for your little angel

sorry about that

thanks

Yes, but the tool I built is only suitable for the 555 test

thank you

thanks my friend

thanks

good idea hhhh

thanks

yes a steady tone means the 555 is bad

I will

testing IC NE 555

Yeah exactly. Software encryption is way to go

I know , but I did this in order to avoid the word "fake" but I got it anyway .. greetings

thanks

thank u

sorry about that

sorry for the bad music

thanks

It was not charger test, it was timer 555 IC test

it's a device for testing timer 555 IC

thanks and sorry

I'm sorry

sorry

thanks

I tried to edit the music but it got worse.. so I deleted it again

no , it's just for testing 555 IC

😂 Grazie

I'm sorry

sorry about the bad music

@@Inventor_AW hey it's ok everyone has their likings but it really is obnoxious and takes the focus off what you are saying. The content is great tho

@@WeirdDuck781 I admit I wasn't very good at choosing the music

sorry
