In the late 60's as a child I received a Fischer Space Pen for Christmas
, because I was always talking about the Apollo program. It had a "pumping" effect on the tip that pressurized the cartridge. I thought it was pretty cool.
There is or was a magazine called Spinoff that documented all the NASA technology that ended up in the public sector. Very interesting and a good counterpoint to those who said the money
spent on space was a waste.
In the late 1940's or early 50's, 9 volt batteries were top secret military technology developed to allow smaller portable radio
In the early 1960's I received my first "transistor" radio
using the same battery
. I would lay it under the edge of my pillow at night and listen to Wolfman Jack out of WLS in Chicago. It was a good time to be listening to rock and roll and since this started at about six years old it made a lasting impression on me.
