Other than price, how is the SparkFun RTK mosaic-X5 different from SparkFun RTK Reference Station - GPS-22429 - SparkFun Electronics?
Amen. I'm probably about the same age as you. We grew up in remarkable times. I followed NASA from Mercury, through Apollo and the moon landing. On the 50th anniversary of the first moon landing, NASA replayed the audio of Apollo 11 on the internet. A coworker who only knew of the moon landing from history books, got interested in the audio replay.
Veterans Day weekend 2016, I met the commander of the final Space Shuttle mission. I told him that Atlantis was the second final launch that I saw, and checking off a thirty year old bucket list. That intrigued him. Chris: "Was it Apollo 17, the last moon mission?" Me: "No." Chris: "Skylab?" Me: "No." Chris: "Okay, what was it?" Me: "Apollo/Soyuz." Chris: *"That was the final flight."
Since Lauren brings up the TI-89, I'll contribute my favorite tech item. Hewlett-Packard RPN calculators. I was a freshman engineering student at USC, the University of South Carolina. HP introduced their HP-35 calculator. I couldn't afford it at the time, but I bought their HP-45. After I married in 1977, I couldn't balance our checkbook using Paula's algebraic calculator, so I bought her an HP-16C, which still works to this day. I have since bought an HP-67, HP-41CV, HP-41CX, with the 41's card reader/writer, and an HP-48GX that I bought at a pawn shop. Since it appears that HP has exited the calculator market, I started hoarding their RPN calculators, HP-12, HP-12P, HPZ17B.
As HP was fond of saying in their print advertisements, "HP has no equal."
Another tech item that I bought in 1980, was the Canon A-1, an innovative camera that offered aperture priority, shutter priority, program mode, stopped down metering, and manual exposure. All of the other cameras just offered aperture priority exposure.
Has anyone hooked up and use the wheel ticks and direction?
For National Radio Day, how about this tribute to NASA's Voyager 2 spacecraft for having the longest distance to communicate. Currently, Voyager 2 continues its mission, more than 12 billion miles from Earth, so distant that a signal from the spacecraft takes 18 hours to reach Earth, and just as long for a return signal to reach the craft. Engineers expect that Voyager 2 will continue to return data until about 2025. https://www.jpl.nasa.gov/news/45-years-ago-voyager-2-begins-its-epic-journey-to-the-outer-planets-and-beyond
