    Hi!
    Is theres any interactive tutorial which can help me to learn basics of
    electronics.
    My aim is to be able to repair electronic devices.
     
  2. You'd be better off at your public library, but there's quite a lot on
    http://www.howstuffworks.com/

    Also use google for anything else.

    Sure, get a breadboard and a starters kit and find some ciruits to build.
    Look at the datasheets for components in the circuit and make changes.
    Does anything happen when, say, you change the resistors on a 555?

    You can learn digital logic (part of electronics) online, but nothing's
    quite like hooking up your 7400 and seeing it happen.

    Electronics repair is obsolete. Everything is black box with red light
    now. Red light comes on, change the box,or card or plug in module. It's
    a throw-away-world. Nobody will pay $150 to fix something that costs
    $75 to replace. Find a better field.

    As with builders and the similar tradesmen , things will be changing
    shortly , not everything costs $6.00

    Electronic troubleshooting and repair isn't dead at all, although there
    aren't that many repair shops for *consumer items*.

    The fun is when you get to troubleshoot a brand new piece of equipment
    that's never been seen before. That's where you really need strong
    troubleshooting skills ;)

    Cheers

    required skills. The last thing I worked on was $80,000 radios.

    yeah, i was going to say something, i just worked on a 10,000 dollar
    ham rig the other day.
    i still can't see how its worth 10k after having it opened but that is
    what it goes for.

    You can troubleshoot anything if you have the prints to it.
    I didn't know there were still some hand-wired ham radios around.
    But as far as repairing multi-layered boards, it's not cost effective
    unless you are a large corporation with hundreds to maintain.

  13. Bullshit. Electrolytic capacitors have the highest failure rate of
    any part in use. the replacements are cheap, and its simple to locate
    the bad caps. You can buy a good ESR meter and some soldering and
    desoldering tools for about $100. Do you have any more misinformation
    to post?

  14. No, just someone who is a tad bitter. I understand him - if VCRs were all
    tube I would have had a job for life. Bloody semiconductors ruined a good
    thing by being so reliable.
     

  15. I learned semiconductors back in the '60s. The only tubes that
    impressed me were transmitter and RADAR tubes. BTW, have you ever seen
    a tube Video Tape Recorder? Ampex made them for a while. The first
    were B&W, and later converted to color. 2" quad heads that cost so much
    you could have bought a nice car for the price of ten hours worth of
    tape. I was offered a working all tube VTR from KBAK in bakersfield CA
    years ago, but the shipping was a couple grand. It would have filled a
    tractor trailer with the spare parts and manuals. It also took about 10
    tons of air conditioning to keep it working.

  16. When I left college I was offered the first computer I learned on for free,
    an Elliot 503 mainframe - all germanium transistors in hand wired modules.
    That needed a lot of AC also.

    You obviously don't work in industry.

  18. You obviously have your head up your ass. I spent 40 years in
    electronics. Manufacturing, Radio & TV Broadcast engineer, CATV
    engineering, and running a service depot for United Video way back in
    the early '80s, along with a few early years in the '60s and '70s in
    Radio & TV repair. I've replaced more bad capacitors than any other
    component. In fact. I have a stack of dead motherboards on my bench
    right now that need about a dozen new 105° C
    low ESR electrolytics per board. I spent my last four working years
    building $20,000 and up telemetry receivers. NASA, NOAA and other
    government agencies but them by the dozens, including one aboard the
    ISS.


    Go to and tell them that electrolytic are
    a huge problem.

    Great site, you cover some of the areas I was having trouble with, like
    power dissipation which none of the books I've bought bother to deal with.
