what IS the minimal (but still somewhat stable/safe) components needed?
Despite what the symbol is, caps less than 1 uF are typically unpolarized, and >= 1 uFare typically polarized.
Lithium coin cells are usually 3.6 volts, not 3.0.
this can not (should not) be a chip by itself project... IMHO.. I mean I need it to be small.. but I want it to work and be somewhat stable! lol
