Resistor Finder
_______________

4/2/94 version 1.0

I wrote this program (rf.exe) because every once and a while I needed a really 
weird resistor in my audio circuits.  If the resistance was not a standard 5% 
or 1% value, it was trial-and-error with the calculator to try to series or 
parallel two standard resistors to make the needed value.  This program helps 
solve that problem by giving you a list of standard 5% or 1% resistors to make 
a non-standard value.

This program was written in Microsoft Visual Basic version 3.0.  To run the 
program you will need the file "vbrun300.dll" in your windows directory.  I do 
not supply it here.  You can get it from the Microsoft BBS at (206) 936-9735 
or in Channel1's free files (vbrun300.zip) area.  

To install this program, just add rf.exe from the File, New menu in Windows.

Running rf is easy.  Enter the resistance you need in the "Desired Resistance" 
box and click "Find".  If you enter the word "all", all the standard resistor 
values will be shown.  Rf will show all series (# + #) and parallel (# || #)
combinations.

Check the "Use 1% resistors" box if you want the program use standard 1% 
resistor values.  Otherwise the standard 5% values are used.  Looking up 1% 
values takes longer.

I supply the source code (rf.frm) for your hacking pleasure.  Please let me 
know if you find a faster way to do the lookups.  One of these days I plan to 
add a feature that shows the resistor color codes of the 2 resistors selected 
from the list box.

This program is free.
