Right. Of course the academics weren't interested. It was useful and

I think what he wants to say is that energy break even is many years down the road,
possibly decades. And fixing and maintaining it might kill the small net energy surplus.

If there is enough sun to power the lights, you don't need them.

Someone who starts out competent and gets a PhD can do amazing things.

I agree with you here. I have worked with some guys in the

Electromagnetics lab at Ohio State University. All , absolutely top
rate . I worked with some PhD types at Raytheon quite a few years
ago. they were top rate too.

I think the people on this board are looking to compare their circuit
design expertise with a PhD's circuit design expertise. Most PhD's do
not do circuit design, so it is not really a fair comparison.

But how about Barrie Gilbert from analog devices (He is a Dr. - it may
be honorary - he sure has earned that if it is - but I assume it is
regular PhD). His designs have made my life so much easier in many
cases. case in point , the low cost log amps that came out about 10
years ago. Absolutely breathtaking.

Of course, someone who starts out _incompetent_ and gets a PhD will do
amazing things, too -- it's just a different sort of amazement.

That is true too, but I think it is not as frequent as the circuit
designer crowd wishes it to be. Now if you want to rag on PhD's in
other fields like edumacation - ......

Add to this the fact that hardly any electronic devices are built so

they can be repaired. You can't even get some of them apart! When you
can, there are specialized parts that cost more, (when you can find
them), than a new appliance.

I just opened a microwave oven. All the expensive parts, (transformer,
magnetron,etc.) were OK. The little control pc was bad. The
replacement part included the front panel and display and cost $72. I
bought the oven 3 years ago for $99.

Why would they? I caught the tail end of that. Once the market
became better at serving the desires of electronics consumers,
the money part of it no longer favored DIY.

I had the great fortune of relatives bringing me broken kit
to fix, under supervision. So can you do that with an iPod?

I had these great Radio Shack kits, where one would trap
discrete components under springs to make circuits. These were
designed to make electronics feel like anything but deferred
gratification.

Odd, saying this makes me feel spoilt. Privleged.

http://www.radioshackcatalogs.com/

I remember the shock at the first Japanese solid state rig
they sent me. Nothing made sense. I could make neither hide nor hair of
it. It was optiomized for something I could not visually disentangle. It
wasn't built like a series of Wisconsin dairy farms, with PS
over here, preamp over here, power section there. It was , as is
the wont of island cultures, optimized for the use of materials
and it used hack beyond my ken.

So beyond that point, I stopped doing it. About the age of 15. There
was a death in the family that shifted the balance of power to
where that didn't happen any more. And I had other interests.

But there was a span of time where I would tell my father "Dad, I
need to use your orange stick" and that meant I needed to use that
and the meter and the whole schmeer. It was a ritual of
acculturation, an invite into the recesses of the family that
really meant something. People that got away from Hank Williams
and Steinbeck with a slide rule and perspiration.

I threw all that away and became a Software Weenie. As I remain to this
day. But I still know how to use an orange stick. If you can't find
one, a corn dog stick is pretty good. If you're really hard up, a
chopstick will do. 90% of WTF? problems are microphonic.

One of the huge mistakes in academia. Right up there with universities

Why not self-publish it on a web site and make sure search engines find

Those IEEE papers are vetted before being published. I don't think it
would be a good idea to publish a paper without some sort of peer
review. [And still look what they publish!]

There is some whack job in South Africa that writes papers as if they
were publications. The theories he espouses are just plain
scientifically without merit.

I think self publication has merit if you have some trusted engineers
to review the paper. You generally need this anyway since what is
obvious to you may not be clear to someone reading the paper without
your background.

Incidentally, any paper that have "novel" in the title is highly
suspect.

Not really, there are just far too many cooler distractions for kids these
days. Before you had consumer computers, the internet, video games, mobile
phones etc etc if you had "the knack" or interest in technical stuff then
hobby electronics was the obvious natural progression. Now it's not obvious
any more and is obscured by all the other techo things kids can take up
instead.

But surprisingly it's making a comeback of sorts through the so called
"hackers" and "makers", perpetuated by Make magazine and various hcked
gadget forums and the like. 5-10 years ago this area didn't really exist,
but now it's cool again to hack stuff, a good lot of it electronics
oriented.

I have heard this story over and over from manufacturers but I have not

My batteries are 14 years old and still going strong. There's a pretty

They're the bare minimum size in the context of my consumption -
