Momentory Switch to Toggle On/Off
Suggest you don't.  Momentary-toggle switches, especially badly-debounced ones, are nasty in real life.  Note that wear and tear on the button mechanism can do horrible...

DRV8305 3 phase stepper driver control
Except it shouldn't be!      You don't need a tach for a stepper motor.  It will step as fast as it's told to!  No more, no less!   Unless...

DRV8305 3 phase stepper driver control
Huh.  Point taken - that is indeed a three-phase stepper motor.  Unusual!   I'm not sure your DRV8305 is going to be happy with it...  but that's a different...

DRV8305 3 phase stepper driver control
Three phases is also very strange for a stepper motor, so are optical encoders.  Are you sure these aren't three-phase BRUSHLESS motors?   If they are, in fact, steppers...

Anybody have any data on Pittman HP plotter motor with shaft encoder?
Typical settings for an encoder like that would be 250 fringes (slots) in the disc, and when you pick up all four edges you get 1000 counts around.  Encoder people like...

Timer timer, who's got the timer? (not the 328)
You didn't start counting Timers at '1'. did you?    S.

328P sleep current wildly different between two copies
A quick poke around shows a decent 100µF 6.3V electrolytic cap is expected to leak tens of microamps.  No, that won't take you to 150, but if you need 0.2?  Yeah. ...

Algorithm to determine if any number appears more than once in list
a) Randomize the list. b) Compare the first two items.  If equal, report duplicate. c) Repeat until you're sick of it.     S.

328P sleep current wildly different between two copies
Maybe a bit late, but I'll make one more stupid suggestion:  Smoke all the caps off your Arduino minis.  Start with the "big" electrolytic, if there is one.  Yeah,...
