Re: [Kicad-developers] [Discussion] PCB Calculator: Resistor calculator

Recently there was a user with similar wish in the forum
for E12 parallel/serial calculator (what is your lower tab ?)

You will find another code for E values <12 on my web page as E96
from the IN30TCD page are already available with many values:

Combinations with two/three/four considered automatically if its worth.
See the description on how the formats for parallel serial are shown.
Should be easy to convert from Java to C. I rarely used for inductors 
and capacitors as they have typical higher tolerance what normally does 
not need exact match for the design. Would prefer a separate tab for 
filter design and AC calculations

Dmitry,

I find your English perfect and your calculator a good start.

Personally, I use calculators when I cannot do something in my head 
easily or fast.


On that note, in the upper block, I would recommend:

- also calculate second component when first value and result are given

- given voltage across components, calculate power dissipation, voltage 
across each, etc.


- how about adding combination circuits RC, LC, LCR, etc. and 
calculating corner frequency, impedance, etc.


You can search online electronic calculators to find more ideas to make 
it more advanced.


That would be my wish list. Thank you for considering.

Hello, everyone.

Now I'm working on the resistor/capacitor/inductor calculator.
In the attachment - very preliminary version of the design.
Upper block - for calculating result from two known values.
Lower block - vice versa, for finding the configuration and values of
two components for target value.
Please, don't hit me too hard, I did this while crossing the Ballmer Peak.
I really hope for feedback and opinion.

P.S. And sorry for my bad English. English isn't my native language, so
I swear, I try to work on it every day.

Hi Dmitry-

This looks like a good start.

I'd prefer if we did not bother with the "Calculate" section.  This is 
light calculation that shouldn't need extra space and maintenance.


The Synthesize section is very useful especially if you are planning on 
giving tolerances in the potential outputs based on the various 
resistor/capacitor series.


The box spacing is not even between your three columns.  RCL, Calculate 
and Formula are at different heights.


I'm not sure that we need two windows for the output.  I'd remove the 
"Result" window and put the results in the window on the right.


In the synthesis, I think you just want a single input resistance value 
as the target value.  Then, you should have the option for 2x/3x/4x 
resistors in the calculation result.


Thanks for taking this on and I look forward to seeing the code result.

Best-
Seth
