wasn't the Variac the name of the computer in Desk Set with Spencer Tracy
and Katherine Hepburn?

Subject: +Variac - More questions
To: homeroast
I have read quite a bit about the use of variacs with iRoast roasters.  I
have a variac and an iRoast but I still have some questions.   I understand
(I think) that a variac will even out the voltage so one can obtain more
consistent results (from say a kitchen, garage w/ extension cord, or right
next to the circuit board).   Here are my specific questions...
1.   Why do I blow fuses with my Variac (only tried it once).
2.   Logic behind being able to do multiple roast with the use of the
variac.
3.  Where the heck does one set the variac knob???   Or does it not matter
as long as it is in the same place.
4.  Other advantages to using a variac.
Thanks

I remember the meaning of the term "Eniac," it was the first actual
programmable computer: the
Electronic Numerical Integrator and Computer,* *it could do about 5 kilo
FLOPS with nearly 20,000 vacuum tubes. Even using the high reliability
military version of the dual triode 12AX7, there were several guys cruising
the place with wheelbarrows full of the tubes so as to do a hot swap in case
they spotted a tube with no glowing filament.
This was in the late 40's, just before Bardeen, Brattain and Shockley, of
Bell Labs invented the junction transistor. Look, Ma- No Filament!
Even in the mid 60's, we used the very same tubes by the thousands in hybrid
(Tubes and transistors) computer circuits in military flight simulators.
Somebody drank a lot of coffee in the day, with all the percolators around
in the break areas. The equipment itself would not run too well with coffee
shorting out high impedance analog signals.
It was not my beverage of choice at the time. San Miguel- ayos na ang
Kasunod!

I am Certified, not enough coffee. The Eniac used, not "the high reliability
military version of the dual triode 12AX7", but the 6SN7 version. When I
started playing with the 12AX7's, it would have been in the late 50's and
they were pretty new at the time.
Again, not enough coffee- anyway nothing like this Costa Rica SM select
peaberry! This is the last of a Fiver I received almost two years ago. The
flavor and aroma continue to peak for me at C+ to FC+.
I had shared several ounces of this roast with a friend, and I recommended
that with his drip brewer and "Brew Pause" basket and weed whacker grinder,
he try to increment the grind more coarse to eliminate some of the fines
that brew funny.
He already rinses the paper filters, so I said to use twice the normal
quantity of coffee.
Pour water at a full boil right into the basket and slide it back into the
brewer.
After two minutes, replace the pot, let a cup or two drip out and turn it
on.
"Ray, I've never had coffee that didn't turn bitter when I brewed it that
strong. Sweeet. Would you sell me a couple of pounds? We don't to run out,
now!"
Heh, heh, heh...

Got Grinder?
