So I've begun working with really small SMT components under
microscopes and my hands are just way too shakey. I've never really
been a coffee drinker and I find things to rest my wrists and forearms
on but it is still pretty bad.

Are there any exercises or vitamins I can take to aid this?

It's possible you are just using too much magnification. Less mag and
a wider field of view may be better.

whoops i think i clicked reply to authors..

well, this is noticible even without magification, on my SMT project
it was a real hassle and I had my girlfriend do it. It also applies
to photography hobby.

Rest your hands on the table and just use the muscles of your thumb and
first two fingers. Much less shaky even than the wrist.

As John L recommends, a lesser magnification would probably help.
Inspect, and perhaps touch-up, under the microscope but work with
something like an Optivisor. The five diopter (2 1/2 x) model is
popular. There are alternates but beware of cheapies with cast acrylic
lenses. http://www.doneganoptical.com/optivisor.php

Jack Daniel's Tennessee sour mash. However, as with many things in
electronics, there are trade-offs ...

Nope. What you need are Gyro-Gloves(tm). Put them on your hands. A
rather large gyroscope spins around the back of the hands and acts as
a stabilizer. The size and pisition of the gyro is determined by the
degree of shaking and which muscles are involved.

No, it's not a joke. I was working on the concept in about 1997 (yet
another dot.com that went nowhere). I don't wanna talk about the
details.

My initial prototype was actually built as a joke. However, when I
tried using it to stabilize my pistol target shooting, I found that my
groups were reduced to well under half or less in diameter. I also
tried it on a friend with Parkinsons Disease, who indicated that with
minimal practice, he was able to function much better. However, he
also indicated that his hand and wrist muscles were fighting the
rotating gyro. Combined with the added weight it was rather tiring. I
also built one to stabilize various optical devices. When I hung a
large gyro on my bicycle, things didn't go quite so well. Same
problem trying to play piano wearing the Gyro-Gloves(tm). I'll see if
I can dig up some photos.

Otherwise, look into various muscle relaxants that are usually
prescribed for Parkinsons. Common Ibuprofen/Motrin might work. For
anything stronger you'll probably need a prescription from a doctor.

Incidentially, most of my shakiness disappears when I'm
concentrating. Lovely stuff, the body and mind, go figure. There are
surgeons who shake like the San Andreas but perform operations as
delicate as any other.

I tried some Cordon Argent once (at, like, 3x the price) but couldn't
tell the difference. Too subtle for my tastes, I guess.

I find most of the brandies too "bitey" to my taste. If I want pure
alcohol I prefer vodka shots served ice cold, particularly good when
served with blinis filled with sour cream ;-)

On a trip to Germany I got bumped up to First Class, and they served
exactly that, and kept 'em coming for about an hour.

In the middle of that night I thought I was going to be sick, but I
managed to slowly sip water and stop my body from rebelling ;-)

I got (dangerously) drunk off Jack Daniels in an underage drinking
binge that TO THIS DAY, one whif and I immediately feel like I want to
puke. Believe it when folks tell you the sense of smell is very
powerful in recalling memories.

And it doesn't even end there! Wild Turkey (and some others) have the
same effect - even though I don't think I've ever tried them. Weird.

On a plus note, I could rollerskate a lot better drunk. (allegedly...)

There might be. The shaking is partly a form of control
loop instability (too much gain and integral effect for the
dead time). Are you, by any chance, on a low salt diet? I
think I heard somewhere that a shortage of potassium ions in
your bloodstream can delay your muscle reaction time (or
maybe it is your nerve reaction time, I'm not a biochemist)
a little, allowing the position control system to destabilize.

You might take a shake of salt substitute (mostly potassium
chloride) on your tongue before fine work. It hits your
bloodstream very fast. Great to quench out muscle cramps,
also.

Of course alcohol and other depressants lower the loop gain,
but that causes other problems with fine work, like you
accidentally sitting on it. ;-)

Fortunately, I fell backwards, so someone was able to catch me...

You need to drink coffee and then solder. Works all the time.

People have different levels of fine motor control. I am blessed with
very steady hands and short sightedness which is a boon in this kind of
work.

How I generally work on very fine stuff is, I rest the sides of my hands
with little fingers on each side of the thing I'm working on; this means
the hands are steady and you only have to worry about the fingers being
steady. I use some 5x or 7x stereo magnifiers and a bright light to give
me a good view of the thing I'm soldering.

For even finer work, below the 0.5mm pitch I've gone to, I've seen
people rely largely on masses of flux to correct errors, and using
solder paste. By the way, although you can get auto solder paste
dispensers which allegedly dispense a controlled blob of gop when you
press a foot switch, as far as I can make out they aren't calibrateable
for the tiny dollops needed for fine work. But my colleague made himself
a dispnser consisting of a hypodermic syringe filled with solder paste
with a screw tightening widget on the back to squeeze ou microscopic
amounts at a time, which works pretty well.

Also keep in mind the trick of using a wooden toothpick to hold down the
top of a component while poking away with a soldering iron.

If my partner is sufficiently interested / invested in the final
assembly outcome she will get me moving on the electronic project once
again immediately after.
