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Electronics repair is obsolete.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

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.

Gad! That upper right picture on your page made me choke!

 

[Lord Garth]

i take it than you don't want to join my club

Well, if it a SSTV club, lets just tune in someone else...

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.

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?

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.

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.

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.

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.
