[Elecraft] (OT) slide rules

Tue Feb 18 21:45:01 2003

The venerable "E6B"?  Yup, I have one of those! Handy damned thing in an aircraft!
Only "flying" I do now (or can afford!) in MS Flight Sim 2002!!
I also have a big Pickett Log-Log Vector rule, along with a Pickett "CREI" rule.
Another rule I have that is especially nice for "radio" work is a K&E "Cooke Radio
Rule".  Makes
it easy to get reactances to quite precision answers.  Have a big circular spiral
scale
Deitzgen rule that reads to around 5 places!

Just think of all the remarkable designs that were done with just them and books and
tables!
I wonder how a computer would have designed the Hoover (Boulder) Dam?

The slide rule will work anywhere, no batteries to run down, no screens to squint at.

| Hell, they still teach with E6-B's. It's circular, but it's a slide rule
| nonetheless. Does time-distance-fuel-speed-density-compressability etc.
| stuff in an airplane. The nice thing is that it works with one hand (the
| other is presumably keeping the dirty side down).
|
| Flip it over (and use two hands) and most do Velocity Vector addition (Wind
| + Craft = Course).

| I have two!  (At least that I can find)   There is another that is a pencil
| cup slide rule, (circular), and somewhere is my favorite 6 inch pocket rule!
| I have a pristine K&E Decilon and my original Pickett.
