Bit of a recreation of centuries past ( & memories of tsh's Slide Rule!)

Digame Analogue Computer

I'll do some more work on this before adding the code to the link above! Anyone else remember these from the old days??

You made that thing? So cool. You're from the original maker generation.

Wow! Op amps!! Virtual ground anyone?

My field. I know they were first designed for analogue computing but how they've advanced in uses.

I love electronics!

Seeing as I mentioned solving the Schrodinger 'electron in a Hydrogen atom' situation, here's the result showing electron probability as a function of radius.
Ground state then higher, more complex spherically-symmetrical solutions.

Here's a link to the relevant LB lesson file. which shows what it is all about and how it is coded.

PS JohnnyD
Yeah, my first opamps used valves. Then discrete transistors- germanium then silicon. First i/c versions were SL701C and 709s and then 741s. Modern opamps are much better in every way!
