Too much capacitance?

Is there such a thing as too much capacitance in a voltage regulation circuit?

I plan to use a pair of  47 uF 50volt caps in my power supply - 'cause that's what I have in my

junk box.  Any problem?  (It will be powering 3 Picaxe08-M's and a L293D motor controller. - power for the motor will be separate)

How do I determine the 'proper" amount of capacitance?

This is my first foray into the robot building business. It is really just an experimental/training platform. It is rather large - base is 10'x12"x14" and the body … Read more

I'm having trouble trying to understand how to use HPWM to control both motors of my 2-wheeled robot.
