A 2023 for of Vera Rubin (neé Cooper, ‘28-‘16) & her discovery that angular motion of galaxies deviates from predictions, 1st evidence for dark matter, now known as 5x as common as matter & the stuff which dictates dynamics of galaxies & evolution of our universe! The Nobel committee waited 3 years after she died to reward another for the theory of dark matter.

She found 6 months mat leave post MSc very difficult 🧵1/n

It ain’t much, but it’s honest work. Az/El sensors serial (SSI) to Arduino board. Removed an RS485 layer.
@adafruit 1/4 size proto boards are cute.

@penguin42 Yep, that may have been a commercial library for Linux, before an open source equivalent existed. Prior to that I was using Xwt and even raw X. The later releases of various open source GUI libraries and desktops was such an major breakthrough at the time.

From the same era, when writing a GUI app in Linux probably meant buying a shelf full of X programming books. I was really, really, into satellites.

Mockup and progress... 🙈 (using DJGPP + dosbox)

Note, however... this toot is not a commitment to completing anything 😛 I can already tell that I'm going to have trouble with some of the math here (and maybe performance).

Just tripped across this blast from the past: my first published article, in an .au electronics magazine.

Remember paper magazines? No? Ok.

@film_girl I made a day trip (via plane) to Portland many years ago, to see an art thing, and people looked at me like I was insane. This proves I am normal, thanks.

Performed some more mm-wave testing at the PNW Microwave build day, looking at the output of the 40-50 GHz quadrupler. Thanks to W7GLF for bringing in his spectrum analyzer & external mixer. Results forthcoming.
