/diy/ - Do It Yourself

Electronics engineering student here i got into it because i wanted to be able to put up a fight vs planned obsolescence

I have learned way too much about how electronics are made and now when possible i usually DIY my own stuff to be as durable as possible,

However even when i do have and know how to use an oscilloscope, and a multimetter, LCR metters and logic analizers, right now i have a broken 40 inch sony TV and a Canon printer that out of nowhere are not working, i already checked what i could do, sometimes it’s an integrated circuit that its not available for the general public, sometimes they just put a god damn black blob so you don’t see what integrated circuit they are using , or sometimes it gets so complicated that I get desperate (and im a very patient person)


I still need way more knowledge and years of experience as an engineer to attempt to repair (and not replace a module) of this stuff, it kind off pisses me off to the point im considering not buying them again and just do my work by hand and never ever watch TV again (full of adds anyway), however my parents are the ones that insist on having everything big and new without thinking because they feel “poor” if they don’t have the stuff “everybody” has
Through my journey i have seen how even electronic components are getting cheaper and weaker in every possible way, litteraly made to be as cheap as possible and to to barely be able work, and the more digital circuits are involved the more the chances of it not working in a short period of time,

In short my advice “Analog and old” is way better than “efficient and new digital stuff” or at least you can repair it easily instead of investing thousands of dollars in equipment and years of study time for just to find out you cant repair it because of coorporate greed and bussines plans
