How should I watch tear-down/repair videos ?

[gouthamec141]

There are numerous tear-down/repair videos in Youtube by many experienced electronics hobbyists (such as oscilloscopes, signal generators Displays etc etc). But my problem is I am not able to completely appreciate these videos, Whenever I start watching a tear-down/repair video the beginnings are always interesting but I am mostly struck in the middle (may be I dont understand the working of some components). Usually the host gives information in some higher level of abstraction which I cannot consolidate at present. But sometimes I notice that the longer I investigate about the particular product the more I understand, sometimes things get very scary (may be because I didnt understand anything) and usually I found myself avoiding these kind of videos and I surf the web looking around some "tutorial-kind-of videos". So, what should I do in order to appreciate the workings of the inner electronics in a practical machine, or simply what should I work on in order to understand the higher level abstraction narrated by the host.


Thanks !!

watch everything you can, if there is something you dont understand just google/wiki for it or find a video on that subject and spend some time sidetracked!

It's similar to my own experiences, i dont know a lot about EE, just enough to tinker around sometimes but always enjoy learning about new stuff. I'm often reading up on stuff after i have watched something.

You need to figure out how you learn best, i do tend to forget a lot of what i read. I learn best from practical work. you just have to find your path. Oh and you cant learn everything in one go!

My approach is to watch as many as I can, even if I don't understand them.  I watched a load of mikeselectricstuff videos, particularly the ones about reverese engineering iPod screens.  I maybe comprehended 70% of what he was saying and understood 40%.  But the more I watched, the more I understood.  I'm nowhere near at the point of being able to remember it all, but now know enough to understand what's going on.  After a while you get to realize that, like any other technical subject, there are basic building blocks and techniques.  But few, if any, of the videos explain those - it's kind of assumed knowledge.  That's fine with me - I'd rather get stuck in to something a bit over my head and learn along the way.

Make sure you have the basics first, Daves fundamentals Fridays, consider some educational material, a course or some beginner books.
If you get stuck on a particular part, then stop and do a google, find material for that specific part/technique and learn that. Then return and try and incorporate that into the teardown.

As said don't stop watching, never stop learning.
Sometimes it can be pretty intimidating watching high level people like Dave, Shahriar and Mike. Don't be put off by that, everyone has to start, and the growth is exponential.
Also, don't be afraid to ask, I have found people here very helpful.
Even the top guys will stop and take time to help, Shahriar even stops to have a giggle from time to time too

Personally, how do I watch Dave's teardown videos?
Naked!
Think I heard an antipodean wince then!
