PCB designs with viewers:
If you want to do a project with me in the form of an episode, there are a few requirements:
1. You must be the author of the project from A-Z
2. Make it available for others
3. If the above points are met - you create an account on PCBWay using the link above (this is important), add your project to the Shared Projects tab and share it with the world :)
I think it's a cool way to do something with you and for you - if you want to implement a project with me, write to me by e-mail: rzezbiarz.tytus@gmail.com

Hey guys, today the first "training" on the channel - free of charge, but if you would like to financially appreciate my work so far, I will be very grateful to you :)
I tried to make this video have maximum training value and answer the questions:
How to find electronic short circuits, burnt components, how to make measurements without diagrams, repair impulse converters, e.g. chargers and power supplies, etc.
And whoever read the description to the end, please write in the comment: "Supporting the Channel" :)

05:43 PCBWay
06:08 Inspection under a microscope
13:30 Theoretical introduction to diagnostics and measurements - simplified diagram of a pulse converter step by step :)
20:05 Practical and theoretical discussion of the NCP1207A and ICE3B0565 application diagrams in our case of the CTEK MXS 10 charger
27:36 TRANSOPTOR 817C as protection against too high voltage on the secondary side (output) of the converter - working with a Zener diode
