<p>David, I wasn't refering to your scope. Agree old scopes are cool
(or not, they are really hot energy eaters). I'd love to have a
bunch of them, but only to look at them and maybe show some
unimportant waveforms so they look nice. Unfortunately I don't
have so much space for storage. And USB scope is not my thing, I
haven't used it in years.</p>

<p>Totally agree.</p>
<p>What may not seem so obvious, there's a catch - when you can
afford all the fancy tools you dream of, then suddenly your
creativity drops down the floor. With crappy tools you have to
be more creative and think, imagine, explore, experiment. For
example soldering - you have to learn how to solder anyhow, and
cheap soldering iron is not forgiving, so it will force you to
think what you're doing and be totally aware of what to do in
certain situations. I have bought my first temperature
controlled station about 20 years after I started soldering.
Only because of that I could appreciate it. In case you wonder,
yest it's possible to succesfully solder SMD with transformer
soldering gun.<br>
</p>
<p>The scope is essential, I think even more than multimeter, but
today you can buy small toy scopes for below $100. And frankly
they are better than big 50kg scopes I had in school. I have
quite a few of those toy scopes, this is my small addiction, so
if you want to ask about specific model, I probably have that.
Don't buy "best scope you can afford", or "scope planned for the
future". Those times are over. Now there's new scope coming
every year, cheaper and better than others. After 2-3 years
you'll know what to look for, and it will be more GAS hitting
than real measurement needs. <br>
</p>
<p>It is very unpopular point of view here, but I think modern
digital scopes are much better that vintage analog Tek.<br>

<div dir="ltr">While I agree that spending $1k will definitely
get you set up, we aren't all so lucky. Especially when we're
spending money made mowing lawns or working minimum wage as a
youngster. What I meant was that a quality iron will really
make the biggest improvement. That plus an "it works fine"
multimeter and a working 20MHz oscilloscope used is almost all
you need (less parts but that's subjective) to do some
damage. Take the price point down from $1k to something more
like $200-$300 or less and that's attainable for a lot of
people.

class="gmail_quote">I learned this stuff as a kid through
trial, error, burned fingers, and Radio Shack. I never had
more than ten or so dollars on hand, so no voltmeter, no
breadboard, no spools of wire. I remember building the basic
556 “Atari punk console” circuit and just thinking it made
horrible noises nobody would ever want to hear.<br>
After building light-controlled oscillators for a year, I
started checking out books at Colorado State University. The
ancient books were the best: Musique Concrète and this book
written in Spanish from the 1940s showing how a film loop
generating optical pulses going into a modulator circuit
could be what we call a drum machine. My mother told me
about the Telharmonium in Worcester MA she read about in
Yankee Magazine. I built a Theremin using an oscillator and
an AM radio, and realized it would be easier to master the
violin than to get a melody out of a Theremin. Then I found
the 1970s books from UCLA on what we now call West Coast
Synthesis. When I got to the log tables in the middle of the
book I knew I couldn’t follow it; if music was math, music
was not for me. <br>
It took a couple of years of futility to realize I had to
try again.<br>
Paia was so inspirational, yet at the same time I felt the
kits were full of design compromises that left me in the
dark about best practices. (I remember testing the Gnome
after my brother put it together and we both thought it was
broken; but it was just the T filter doing its crappy T
filter thing.)<br>
Then I was gifted a broken Paia Proteus when I was a junior
in high school. Fixing that beautiful machine gave me a new
appreciation for Paia.<br>
<br>
Paia turned me onto Don Lancaster and Craig Anderton (as
editor of Electronic Musician). <br>
After I got my hands on the books by Bryce Ward and Barry
Klein, I really wanted to do this stuff, but I had no way to
earn a living, and neither the math nor the music.<br>
<br>
How long does one have to live before you just start doing
what you love? <br>
