Quotething is the PCA9685 module handles the V+ (for each servo) No it dosn't.

Science is about explaining and predicting observed/observable/measurable phenomena - coming up with plausible/backable theories to explain the mechanisms behind the observations. It is built-up on accumulated scientific knowledge - (math, gathered data, physics, chemistry etc).
Switching over to something else (eg. nrf24L01) when the existing device (hc-05) is expected to be workable is certainly an option. But, naturally - it is definitely advantageous to find out the reason(s) for a particular approach being currently unable to achieve your objective ----- which is why you asked about it, and which is good. This enters the area of electronics/electronic engineering, and working towards improving electronics knowledge and skills.
i meant that the whole breakout module that the PCA9685 chip is on has just one pin (two in parallel actually) for the incoming V+, meaning that to insert a Pi circuit for each servo, one has to breakout the 3-pin male headers to achieve the setup of;
if the accumulation is unstructured and quite haphazard in its collection, it becomes quite inefficient and the knowledge is filled with (unknown) gaps.
Size is relative. The smallest inductor is huge compared to a 0805 resistor;
I just want to know which 3.3V regulator you used I am also with the same project.
No.You put the filter between the break out board and the servo.
so you mean like this ?
i can't imagine that's what my DMM was "contributing" ?
what sort of inductance/choke levels would be reasonable for 6V spikes of 100mA ?
is there a formula for this and what would the 'phenomena' be called
meanwhile, on your webpage that you linked, it says using inductance values of tens of milli-henries.i've been calculating what length and radius of coil that would involve and it's *huge* !
No.Like this:-The square boxes are the servos.
Your right it wasn't so that suggests you don't need that much inductance so you only need a small value. That was a general purpose comment for heavy motors.
You can't say without first defining the period of the pulse and you don't know that....the effective resistance an inductor presents when fed with an AC signal. This is a pure inductance where the actual resistance is considered zero.
would the inverse of the pulse(time) be considered the 'frequency'
