Is the sensor analog or digital?
I find analog easier to write for. In a loop, start ADC and get a sample of each XYZ. IF statement to compare sample to greater / less than constant number threshold which turns on LED, ELSE turns off LED.
There are many types of regulators. I know that method works with transformer / rectifiers from generators.
I can't say if a normal regulator that uses a resister network would "go crazy", you would think that it would continue to adjust. If it was me, I would slap one together and take some...
Can't help ya much there.
When I don't have a calculator or matlab available, I used to use a integration/derivative lookup book. It's been so long I can't remember the name, but what the book had was page after page of complex polynomial equations and their equivalent simplified form. Making...
There are a few different methods of voltage regulation. Most common use an integrated circuit with an input, output, and ground. Current only flows one way.
Another type would be simply placing a zener diode in parallel with the batteries. Neither battery could exert a voltage greater than...
I think I made a decision. I am leaning toward a Step-Up (Boost), FlyBack, Sepic.
SEPIC converters are readily available, provide me with the voltage boost I want, and can even handle currents up to 5A.
Wolframalpa can do that

Copied from the Alternate forms section
a = x y z
b = x+y+z
c = x (y+z)+y z
Yes, different voltages will put stress on the lower cell. Is this stress enough to destroy the battery? Probably too expensive to test and find out.
Recommend two voltage regulators, one for each battery.
Does the bike motor need a constant current flow? Probably not. The easiest solution...
Because the current passing through R results in a voltage drop across R.
9V - VdropR = Vcap
t in seconds
C in uF
R in ohms
V in volts
R*C is in seconds
For the rest, I think this page will be of help to you.

Yep, you disable the JTag by setting the fuses. Any comm software for the mkii can do this.
JTag is enabled by default on most atmega chips, need to disable it to use those I/O pins for something else.
