wasn't the Variac the name of the computer in Desk Set with Spencer Tracy and Katherine Hepburn? ---------- Forwarded message ---------- From: jay Date: Apr 2, 2007 5:26 PM 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 -- No virus found in this outgoing message.

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... Cheers -RayO, aka Opa! Got Grinder?
