Wobbulator: a primitive mechanical/electrical sweep generatorThis is a thread intended to accumulate antique words and phrases that seemed useful a long time ago.
You might think of it as a sub-category of The Jokes Thread.
Here are my start-up contributions.
Finger Hum: A form of signal generator used to test audio amplifiers. This version only had one frequency, but it was inexpensive enough that every technician had at least one in his tool kit.
Letting the Vacuum Out: Breaking off the glass seal at the rear of a CRT before shipping it to the rebuilding factory. Some rebuilders required the dead CRTs to be shipped in this condition, some refused to accept dead CRTs without the vacuum being intact.
Diddle Stick: A plastic tool with a hexagonal end, used to detune IF amplifiers in vacuum tube TVs.
I will edit this post, if and when I remember things to contribute.
That evokes memories that I would not rather have.rawlplugs and rawlplug tool, .
My local library still has several cabinets of fiche spools that contain local newspaper archives. It's always fun to see a newbie try to figure out how to find something. I think the librarians enjoy it too. Give the guy the spool and stand back.microfiche
I have always thought of myself as the last living math teacher to include slide rule in the lessons. 1975, Ghana, U.S. Peace corps teacher assigned to a rural secondary school. Very smart fifth form kids and we all learned a lot of tricks on the "slip stick". One important thing that's often missing today is estimating the result so you could set the decimal point. Most high school kids today will get an answer on their calculator but have no idea if it's reasonable.The slide rule was mentioned earlier. The really cool guys owned a circular slide rule.

That's a Casey Stengel quote that actually makes sense. When Mr. Stengel was giving directions to his house the way the streets were it didn't matter which way you turned at the fork because both ways circled around to the same place. BTW, isn't "directions" and obsolete term too? These days you give someone the address, they punch it into the navigation system and off they go. No more tedious directions.When you come to the fork in the road, take it.
Well, it was popular at one point:Nope, though some kids find it hard to find. Try sending them out to get some.
I still use those too, but fewer and fewer as the last company I had to write a physical check for finally went online.postage stamp
