Hello friends. I just joined you. I discovered your forum while searching for schematics. I want to learn electrical and electronics for hobby purposes and want to use my knowledge in repairing my personal devices or producing new things. I apologize for my bad English.

Hello everyone. A few words about myself: my first experience with a PC occurred in 2002. My first computer was Robotron A7150 (aka SM1910, aka CM1910 - USSR version), it had 3 games installed: Sea Battle, Tetris and Boxing. Since childhood, I understood the basics as far as what to plug in where and I tried to hook everything myself. But my interest did not begin with this. Once there was a need to rearrange it for more convenience, since the apartment building in which we lived was new and repairs were taking place during my stay in it, just like many of our neighbors, I decided to rearrange it myself without the help of adults, I took the provided handle on the monitor and the iron heating line running through our floor, I turned off the PC but forgot to unplug it from the outlet resulting in electric shock. I couldn’t figure out why it happened and started to dig in. Eventually that had me obsessed with the topic. I started gaining more understanding of the processes of current flowing through wires. And now I deal with a plethora of PCs, laptops, televisions, and other consumer electronics on daily basis. I am also the subcontractor for a number of small businesses servicing their networks, access control and video surveillance.Comment
