Have bought a #Sharp #PC-500S last Saturday at flea market in Hannover for 20β¬. After changing the caps for contrast potentiometer it's working quite nice now. Prefer the plastic keys in opposite to the #PC-E500 (without the S) π Maybe I gift the older one in my collection to a friend for it's 60th birthday in July π He is looking for that one for a long time now π

Pete SegalDo the calculation
I have accumulated quite a collection of calculators over the years, for school, for work, for fun. So long as the modern grid keeps going, they all work. But, maybe I should review the slide rule instructions, just in case. No batteries, no power, no internet. Just works.
Here's a thought: will all calculation be done by AI in the future and, how should that figure in to math education? Teach analog technique.

Dr. Kirsten D. DzwizaMeton - Virtual Mechanical Moon and #Eclipse #Calculator
This awesome tool was created by prof. em. Thomas Weibel from Basel, Switzerland. Here is the beginning of the description from the website:
"The metonic cycle is a period of 19 years corresponding to almost exactly 235 synodic lunar months or full cycles of #moon phases, named after meton of athens, a greek #mathematician and #astronomer from the 5th century bc."
I love it :-)
pandoraMy old TI 84 #calculator got a new case and a new life! It now has a real #keyboard !
I killed sooo many LEDs during the soldering but fortunately @fesix helped me fixing all my stupidities!
