Super Cool Lightning Calculators!

Hey, everyone. Welcome back (to me, at least). We have two — count ‘em — two new wheels! These came to us courtesy of Brian of Dallas.
These sport the odd measurements of 8.75 by 11.125 inches (and still a bit odd when measured metrically). They’re made of sturdy cardboard and have nifty plastic arms to assist in your calculations. My favorite thing about these wheels, aside from their obvious beauty, are the labels with names like “Micro-Henrys”, “Micro Farads” and “Megohms”. I think The Micro-Henrys would be a good name for a band.

These were produced by The American Radio Relay League, Inc. and bear a 1932 copyright date. It’s almost impossible to see the very nice logo of the Relay League, so I’ve done a little drawing for you. And guess what? The League is still around, but it’s now called The National Association for Amateur Radio and they have the same logo! Their website says, “Join our circle! ARRL Members Get it All!” [random capitals theirs]. They offer a leaflet titled, “Scouting and Amateur Radio: Explore the Ultimate Wiresles Connection!”
