Seriously, I’m really liking this series. You’re making it fun to learn, and I’ll bet you’re having fun making them.
Keep up the good work as always. :)

Give your cat a scratch on the chin for me. \^..^/

Will Adafruit sell a compilation DVD once you finish Z for impedance? If so, sign me up!

Go search on info about the chemistry behind the “lemon battery.” Since fruit juice isn’t zinc chloride or copper sulfate, apparently the battery is driven by zinc oxidation, and the copper electrode doesn’t participate much in the chemistry.

I would guess it’s more likely a (Cu-redox = 0.34) so: 0.34 – 0.85 -> -0.51 which is somewhere between Iron (-0.41) and Chromium (-0.74) and what do you know… many stainless steels (like many washers used in plumbing) have an Iron/Chromium mix.

By the time Z rolls around we’ll already have hit Capacitor, Inductor and Resistor. I vote Z is for Zener Diode!
