Few people have heard of it, yet many consider John Blankenbaker's KENBAK-1 to be the first commercial personal computer.

Koss introduced these headphones over 40 years ago, and they remain affordable favorites to this day.

Listening In On The Apollo 11 Astronauts... From Home

Back in July 1969, amateur radio buff Larry Baysinger managed the impossible by listening in on transmissions from the Apollo 11 astronauts during their historic lunar landing. 

Larry Baysinger and his homebuilt antenna.

The Louisville Courier-Journal reported, "Thanks to some homemade electronic equipment, including a rebuilt 20-year-old radio receiver from an Army tank and an antenna made of spare pieces of aluminum, nylon cord and chicken wire, a small band of Louisvillians was able to 'eavesdrop' Sunday night on the American astonauts' conversation directly from the moon.

The odds and ends of equipment recorded only 35 minutes of conversation between astronauts Neil Armstrong and Edwin Aldrin on the lunar surface and their orbiting companion Michael Collins. But the signals were received directly from the moon, over a quarter of a million miles away, not through Houston Space Center."

Brilliant stuff. I wish we could recapture the excitement of the space race instead of squandering trillions of dollars irradiating vast swathes of desert with depleted uranium.
