• @glibg10b @Rugnjr I ran this past my (engineer) SO and, after grumbling at being nerd-sniped, he came up with something you could measure to derive e.

    He said a capacitor filled through a resistor for a time unit equal to “RC” gives you a simple formula that solves for e.

    I think I may have got that right? Most of this is gibberish to me, but he gesticulated wildly and held up random electronic things at me so I think he had something.
