How many steps in a variac

You assume way to much to make yourself look intelligent but in the eyes of
god you are just another imbecile.

I'm getting closer to a diagnosis of your personality disorder.

(BTW where are the videos of the home-made 4 layer board? Remember:
I'll pay for everything!)

Narcissistic personality disorder sounds about right.

Narcissistic Personality Disorder is characterized by: (At least 5 to
diagnose)

1. Grandiose sense of self-importance (e.g., exaggerates achievements
and
talents, expects to be recognized as superior without commensurate
achievements.)

2. Is preoccupied with fantasies of unlimited success, power,
brilliance,
beauty, or ideal love.

3. Believes that he or she is "special" and unique and can only be
understood
by or should associate with other special or high-status people.

4. Requires excessive admiration.

5. Has a sense of entitlement,i.e., unreasonable expectations of
especially
favorable treatment or automatic compliance with his or her
expectations.

6. Is interpersonally exploitative, i.e., takes advantage of others to
achieve his or her own ends.

7. Lacks empathy

8. Is often envious of others or believes that others are envious of
him or
her.

9. Shows arrogant, haughty behaviors and attitudes.

So much theorizing, so few facts!

The cheap Calrad variac on my bench goes below 1 mV fully CCW, 146
volts max CW. It has a lot of mechanical stickiness, but usable
resolution is around 50 mV. That's about 1 part in 3000, and I'm
guessing it has maybe 200 turns.

The windings are flat in the brush area, and the brush is almost
exactly 3 windings wide.

Oh yeah, flattened windings, I remember that. If they were all point
contact, my above analysis would be correct. However, they are
flattened, so the contact area is spread out and, as the brush moves
off one and onto another, voltage change can be very smooth. The out-
of-phase situation I spoke of would be advantageous when there is some
gap between turns, improving the brush's interpolation.
