One thing I've been concerned about for a while is what seems to be the
lack of electronics building skills. *My* feeling is the desire to work
on this stuff is going away and I'm not sure why. I DO NOT BUY the
argument that components are so small now that nobody can build or hack
equipment anymore as I view that more of an excuse for not building.
It also seems that most (not all) of the people I know that collect
computers now (and used them in the 70's and early 80's) are fairly
competent at working on electronics.
Are kits at all desireable to build by newer entries into electronics
and computers? Or existing builders?

I was talking to a buddy of mine about this at lunch. He's an old ham and
used to build a lot of stuff. We were noting how people don't buy their
kids things like Tinker Toys or Erector sets or anything that encourages
them to build things. I don't know all the reasons why but I've been
noticing for years that FEW people build or repair things. I've tried to
sell electonic companents and tools at the hamfests and no one is buying. I
had a big box of top quality Utica tools for $3 each that I took to three
hamfests and I sold ONE tool. When I was growing up MOST men repaired their
own cars (at least minor repairs) but now very few people even change their
own oil. I look at the modern hot roders and laugh. They hang a different
exhaust tip on their car and think they have a race car! I BUILT my first
car (Meyers Manx dunebuggy). I think the small size of the components
deters SOME repairs/projects but I think that's only a small part of the
problem. Most people are totally clueless about repairing or building
ANYTHING.

It's a cultural thing. And for as long as I can remember those that worked
with their hands were looked down on by those who didn't, and that attitude
seems to have carried over into the present day, even though most of those
"white collar" jobs I see are a freakin' joke, and most of the folks who
hold that attitude couldn't say why they do. It also appears to be a very
much urban vs. rural thing, too -- the more rural you are, the more likely
you are not to have that attitude.

I think its because the tools needed to tinker have started getting
expensive, the schematics are hard to find, the equipment itself is so cheap
and outdated so quickly to bother with, large scale integration of many
circuits into proprietary hard to get chips, logic being done with software,
and most important of all its just not cool to do it. People who tinker with
cars these days do it by buying a new chip some engineering company put
allot of effort into making, or extreme bolt on intake packages and nitrous
for those who like melting engines. Most computer hacking these days just
involves software and adapters that convert inputs and maybe some case
modding. People used to get their shoes repaired too, when is the last time
you seen somebody get their Nikes resoled?
The only tools I use are analog (a decent handheld multimeter). My
electronics toolbox consists of a bunch of screwdrivers, a chip puller,
fluke meter, various memory chips and SIMMs, fuses, battery holders, and
jumper wires. All I need it for is to figure out what is blow and swap it
out with another chip (if its socketed) or replace the board if I have to.
For the equipment I collect its not cost effective to buy a scope and
surface mount soldering stuff to repair a $20 machine or a $5 board even if
I knew how to use the equipment. Most of the people who do chip level work
here used to do it for a living, have an electronics background, or work on
equipment that predates surface mount large scale integration. I would think
the last thing a parent wants their kids to do these days is be a commodity
coder, engineer, or electronics repairman because of the low pay and
offshoring. We are turning into a nation of MBAs, burger flippers,
salespeople, and paper shufflers.

Go buy the one of each of the top 10 computer brands here in the US and list
all the parts manufactured here in the US, 5 years from now do the same
thing and show me the parts that were designed here in the US. All the
manufacturing is done overseas mostly, now the design work is going there
also. I would think the vast majority of EE's are doing installation work
and not design here anymore (those still working the profession).

They do have products to sell, they just happen to be designed and made in a
different country buy engineers who might have been educated and trained
here and then went back to their home country.
The only thing the US and Europe had going for it was inventing industries
and products because of the R&D they used to conduct. Now that R&D is being
done overseas by foreigners you can see our economies are going down the
tubes both in the short term outsourcing of manufacturing and in the long
term brain drain associated with doing R&D in foreign locations with local
engineers.
It is just a matter of time before China cashes in the US dollars it holds
and buys up US tech companies and ships them overseas along with their
patents. Then the MBA's who helped start this offshoring mess will be out of
a job also.

<shrug> It depends on the person and the area. For instance, robot

people that work on cars with custom mods and whatnot, but for special

One thing I've been concerned about for a while is what seems to be the
lack of electronics building skills. *My* feeling is the desire to work
on this stuff is going away and I'm not sure why. I DO NOT BUY the
argument that components are so small now that nobody can build or hack
Nor do I. The larger SMD parts are perfectly easy to homebrew with, and I
am quite sure _I'll_ find a way to use even BGAs as/when I have to. That
said, there are plenty of pin-through-hole parts around still.
Nor do I buy the argument that it's not worth homebrewing as you can buy
a better unit for less. Firstly what you buy ready made is often not
better than that which you could build. Secondly, there are plenty of
things you can't buy. And thirdly, nothing (IMHO) compares with the
feeling when one of your homebrew designs works.
And what about programming? 20 years ago (or so), most people who bought
a home computer learnt to program, at least in BASIC. Many went on to
learn other languages. Now, I'll bet that most computer owners have never
written a line of code in their lives. Even though computers are a lot
more common than they were 20 years ago, I suspect the total number of
amateur programmers has decreased. And yet the programming tools
are now even eaier to obtain than they were 25 years ago (there are free
versions of most ocmmon languages, home computers are powerful enough to
run said free versions).
There are still a number of people in the UK who make mechanical clocks
at home. To make a clock, you can expend to spend \pounds 100 on metal,
and about as much again (if not more) on the gear cutters. That assumes
you already have a lathe, dividing head, etc. And the result is a worse
timekeeper than any 5 quid quartz clock. Don't get me wrong. The clocks
they make are beuatiful, and I would love to be able to make one (in
fact, I fully intend to do so sometime). But financially it makes no
sense at all, unless you consider the enjoyment and education you get by
making said clock -- things that also apply to homebrewing electronics.
That said, though, there are not that many model engineers or amateur
clockmakers in the UK. Just as there are a few, but not that many
electronics hackers. And I think one of the reasons is simple. Most kids
have realised that there is no point going into science/engineering.
There are no good well-paid, satisfying jobs in those areas. Well paid
jobs (at least in the UK) seem to reserved for those who can kick a
football or strum a guitar. And the educational system seems to be
designed to remove any curiousity that a child might have (fortunately,
it didn't work on me).

Try the UK ones if you want to see failure... Chemistry (in practical form at
least) is basically gone, too unsafe - replaced almost entirely by
simulations and theory. The few good science teachers that are left don't get
to teach properly, for fear of some parent suing them because little Jimmy
burned his finger on a Bunsen burner.
Compensation culture is evil. "Everything is someone else's fault". Parents
these days are far too overprotective... Kids don't get to play out for fear
of paedophiles and murderers roaming the streets (two words for you:

Yeah, I've done SMD soldering down to 0604 passives, SOT23 transistors, and
TSSOP ICs. I've even tried soldering down the little leadless packages ADI
use for their uMEMS accelerometers - not too hard, with the right tools and
plenty of rosin flux.
am quite sure _I'll_ find a way to use even BGAs
as/when I have to.
Enamelled copper wire soldered to the balls dead-bug style?
Nor do I buy the argument that it's not worth
homebrewing as you can buy
a better unit for less. Firstly what you buy ready made is often not
better than that which you could build. Secondly, there are plenty of
things you can't buy. And thirdly, nothing (IMHO) compares with the
feeling when one of your homebrew designs works.
Hell yeah.
Even though computers are a lot
more common than they were 20 years ago, I suspect the total number of
amateur programmers has decreased. And yet the programming tools
are now even eaier to obtain than they were 25 years ago (there are free
versions of most ocmmon languages, home computers are powerful enough to
run said free versions).
It's a bit much to expect the average Joe to learn to program when he can't
even learn not to open the EXE attachments on his emails. "But it was from a
friend!" / "And it takes five seconds to email back and ask 'Did you really
mean to send me this? What is it?', so why didn't you do it?"
FFS, if you're going to buy a computer, you might as well learn to secure it
properly. There really should be a requirement for licensing of computer
owners/users - if you can't prove you can secure a machine properly, you
don't get to own one...
And the result is a worse
timekeeper than any 5 quid quartz clock. Don't get me wrong. The clocks
they make are beuatiful, and I would love to be able to make one (in
fact, I fully intend to do so sometime). But financially it makes no
sense at all, unless you consider the enjoyment and education you get by
making said clock -- things that also apply to homebrewing electronics.
It's the beauty of the thing that's appealing though. You'll never find a
clock in a shop that looks anywhere near as nice - everything you see these
days is plastic, plastic and more plastic.
And I wouldn't be so sure about quartz clocks being more accurate, especially
the cheap ones... I'd rather tie a GPS receiver to a PIC and build a "totally
accurate clock" of some description.
That said, though, there are not that many model
engineers or amateur
clockmakers in the UK. Just as there are a few, but not that many
electronics hackers. And I think one of the reasons is simple. Most kids
have realised that there is no point going into science/engineering.
There are no good well-paid, satisfying jobs in those areas. Well paid
jobs (at least in the UK) seem to reserved for those who can kick a
football or strum a guitar. And the educational system seems to be
designed to remove any curiousity that a child might have (fortunately,
it didn't work on me).
Me neither. I pissed my science teacher off no end by continually asking "So
if X does Y, how does Y work?" type questions. Got hauled in front of the
headmaster a few times for that, too. Still didn't stop me. :)

Yeah, and some of those plastics degrade over time, too. Get brittle, and

Also, minor quibble - I have no problem with incompetent idiots owning
cokmputers, any more than I do with incompetent drivers owning cars.
It's only when they connect to the net - or want to take them on the
public roads - that there's any reason for the State to get involved.

You know, I think those sorts of skills will come back, at least in Europe.
Landfill taxes are set to go through the roof in the next few decades, and
there will likely be all sorts of Government incentives to persuade consumers
to repair and recycle equipment rather than simply dumping it as they do now
- hopefully there'll be a lot more call for skilled repair people as a result.
Not sure what the situation is like in the US though - after all there's a lot
more space, and so far there doesn't seem to be much concern for using what we
have rather than simply making more (I realise that probably isn't true for
inhabitants of this list :)

Agreed. And that probably applies to almost any building activity.
Even getting my first flat-pack cupboard to stand upright many
years ago was a source of some satisfaction :-) But I certainly
didn't start out thinking that I would enjoy the feeling of
successfully building something. For me it was mostly because
I had a couple of friends who were into electronics plus I
enjoyed anything scientific anyway.
And what about programming? 20 years ago (or so), most
people who
bought a home computer learnt to program, at least in BASIC. Many
went on to learn other languages. Now, I'll bet that most computer
owners have never written a line of code in their lives. Even though
computers are a lot more common than they were 20 years ago, I
suspect the total number of amateur programmers has decreased. And
yet the programming tools
are now even eaier to obtain than they were 25 years ago (there are
free versions of most ocmmon languages, home computers are powerful
enough to run said free versions).
But most of the computers sold today are tools (to get on the net,
to play games, to write letters etc.). I guess gaming played a
part too even back then, but you were much more likely to be
exposed to programming if you had to type in a listing from
a magazine before you could blast your aliens!

There are still model engineering clubs around. There's one in north
Oxford, they even display their home-built trains on a purpose
built track. Last time I was there (which was a few years ago now)
there were even some younger members (late teenagers, early twenties).
And there are a few of us at work who can pick up a soldering iron
without leaving burn marks on skin. Not that any of us are actually
_paid_ to do that though. Job satisfaction is still to be had in
those areas (I enjoy my job, for example), the problem is convincing
the anyone that it's true and will remain true for long enough for
them to get started on the career ladder.
Well paid jobs (at least in the UK) seem
to reserved
for those who can kick a football or strum a guitar.
I won't argue that some of them are not well paid, but a
fair few of them don't seem to be able to _consistently_
kick a ball well :-)

I disagree with this quite a bit. There are plenty of projects out

avrfreaks.com, people in the Microchip forums, homebrew CPUs, etc.
There's no loss of desire at all. Sure, maybe it's not all built of
TTL, but so what? TTL is slowly going away (IMHO), in favor of micros,
FPGAs, and PLDs. To say the interest in building skills is waning just
says to me you're not looking in the right places.

I think you're probably right about this. I have had many thoughts about
building computers over the years, that kept on morphing into different
things as time went on, but eventually I just acquired some working hardware
and started _using_ it. Which, in spite of my continuing to accumulate all
sorts of hardware bits these days, is still where I end up spending most of
my time.

I suspect you mean "PC board" :-(. Try building a radio on a breadboard!
Screw down the transformers, octal sockets, etc., just like they did 50

Alternatively, a lot of really good radios are built on nothing but

Two years ago, I built a COSMAC Elf right out of the pages of the
1977-1978 Popular Electronics articles, on perfboard, down to the 1861
'Pixie' chip. The most modern facet of my implementation was that I
couldn't find a 74L00 for the clock divider, so I happen to have a
1970s TTL part in there at the moment.
Some of those old projects can be hard to find parts for (especially
the RTL-logic-based projects from the early 1970s), but there's plenty
of material to work from there.

I suspect you mean "PC board" :-(. Try
building a radio on a breadboard!
Screw down the transformers, octal sockets, etc., just like they did 50
years ago.
Two years ago, I built a COSMAC Elf right out of the pages of the
1977-1978 Popular Electronics articles, on perfboard, down to the 1861
'Pixie' chip. The most modern facet of my implementation was that I
couldn't find a 74L00 for the clock divider, so I happen to have a
1970s TTL part in there at the moment.

Hi,

Sometimes what you want is simply not available ready built, or the kit one
is better/cheaper than ready-made. See:
http://www.elecraft.com/ or http://www.ten-tec.com/
for some American kits. The radio kit market is doing quite well atm.

have the ability to build their own gear, the desire is at least partially
driven by the cost of ownership of whatever gizmo the kit turns into. As
most any gizmo is now readily available at some ridiculously cheap cost, at
least as compared to an equivalent kit, the kits are not in demand.
Yes. There's little or no fascination with building a radio when you can buy
a radio that's cheaper than the kit...

It also seems that most (not all) of the people I know that collect
computers now (and used them in the 70's and early 80's) are fairly
competent at working on electronics.
Are kits at all desireable to build by newer entries into electronics
and computers? Or existing builders?
There are a lot of things to build that are not "computers" in the
box-that-sits-on-a-desk-with-disk-storage-and-CRT-and-keyboard realm,
but are interesting electronics.
Lots of fun is to be had playing with microcontrollers for all sorts of
purposes.
Analog computers are always imminently hackable. Try building a circuit
for integrating the Lorentz equations for example. Turn a knob, and you're
tweaking the constants!
At the anti-digital end, some of us are still building radios with tubes
and coils :-).
I'm not going to say that there is no computer stuff to be built,
I'm just saying that many of us have been there, done that, and now
choose to do other things which we find more fulfilling.

Don't forget things like building your own earthquake detector or
weather station. I have a kit book for these sorts of projects. They
are fun, cool to integrate with a uP for data recording/analysis and
are easy to build with low-cost components and electromechanical gear.
My interest in this sort of electronics is in making weird
electrokinetic sculpture type machines. Survival Research
Laboratories, anyone?

Because you can buy X for much less than it would cost you to
build X, in fact you can probably buy X for much less than the
cost of building the subset of X that you actually want.
It must be very hard making a living wage fixing TVs etc. these days.
You can still make money designing electronics (at least we employ
some such people in the UK so I assume they earn at least enough
to eat :-)) but I'm not sure that this will continue to be the
case for much longer. The same goes for software engineers like me.
There's nothing that we do that could not in principle be done
almost anywhere else in the world - and there are plenty of
places where it is cheaper to hire workers than in the UK.
I'm sure that argument must be pretty obvious to most people
(perhaps not to teenagers, but certainly their parents must
know and the vibes will filter through).
BUY the argument that components are so small now that

I do not buy that argument either. Most people never even open
the box up so the size of the components is not something they
know about! For that matter, most people do not fix their
washing machines or dishwashers or vacuum cleaners ...
and none of those (that I've had to play with) have small
components in them.

I had my $500 Sony TV repaired the old fashion way last summer.
For $200 total or so, out of warranty, a guy from a big TV/appliance
regional chain drove 40 minutes, debugged which transistor was
flakey, then made the return trip with the replacement and
resoldered it right there in my living room. Fairly old school,
maybe 55 or so. But looking inside the TV, it was clear there
weren't that many non-IC non-daughterboard parts. My problem was
relatively simple; the TV wouldn't turn on reliably.
But so few things are repaired these days. I know the IT people
at several nearby school systems. Regional consortiums (called
CESA in WI) once repaired their small electronic equipment, but
now they're gone and now they're stuck. Where to go to repair
a laser printer? An overhead projector?
It was the CESA that once provided the dial-up DEC access that
I used in middle school and high school, circa '77-81.
The writing is on the wall for so many TVs to be replaced by
purely digital devices. Not all, but many. Look at the average
Joe and Jane who see the Media Edition bundles for $2K or so
at Best Buy - the salesdroid tells them they can load 90 DVDs
or 200 CDs to the hard drive or get movies off the net, they lust
over the big flat panel, and the lightbulb goes on over their head.

I'm wondering why you didn't just grab the service manual from the shelf
and track it down yourself... It couldn't have taken that long.
Actually, that's one reason I repair instead of replace, even on old
stuff. Having invested in the service manual, and in some cases made up
extension leads. test jigs, etc, I don't want to have to do all that
again because I've bought some new device.

In the UK, if TVs are repaired at all, then the daughterboards are also
repaired to compoennt level, even when they contain 100+ pin SMD ICs.
Boardswapping in consumer electronics is relatively uncommon over here,
at least from what I've read.

And just how many components are there in an OHP? And how hard is it to
trace the fault with nothing mroe than a multimeter?
