fizzyCal - Physics / Electronics Calculator

Purpose
-------

This program is aimed for the Physics enthusiasts that may also have a knack for building electronic projects, especially if they happen to be guitar-based effects, in other words, for people like me ;)

General
-------

Click on the "Switch On" radio button to activate the desired calculator.
The "Clear Entries" button clears the entries of the selected calculator.
The "Clear *" button clears all the on-screen calculator entries, regardless of which calculator is active.
The "Calculate" button performs a calculation on the active calculator.

Calculators
-----------

1) Ohm's / Joule's Law calculator
------------------------
  V = Voltage
  R = Resistance
  I = Current
  P = Power
Enter two quantities to find the remaining two.
  i.e. Voltage and Current to calculate Power and Resistance or Power and Resistance to calculate Voltage and Current and so on.

2) Voltage / Current / Power to dB / dBm converter
--------------------------------------------------
Options:
  V|I|P <--> dB : Convert Voltage, Current or Power difference to dB difference (and vice versa).
  P(V|I) <--> dB : Convert Power w.r.t Voltage or Current difference to dB difference (and vice versa).
  P <--> dBm : Convert Power to dBm or dBm to Power (relative to 1mW of Power).
  VIPi = 1st measurement of Voltage, Current or Power.
  VIPo = 2nd measurement of Voltage, Current or Power (only for V/I/P <--> dB).
  dBDf : dB or dBm difference, depending on option selected.
Enter two quantities (VIPi and dBDf or VIPi and VIPo) to find the third (in case of V/I/P <--> dB).
Enter VIPi to find dBDf or dBDf to find VIPi (in case of P <--> dBm).
In either case, the "Gain" displays the ratio between the two quantities (or VIPi/0.001 in case of P <--> dBm).

3) Impedance Equivalence Calculator
-----------------------------------
  f = Frequency
  C = Capacitance
  L = Inductance
  Z = Impedance
Enter two quantities to find the remaining two, as well as the equivalence of Capacitance / Inductance for a given frequency and impedance.

4) Potential Divider
--------------------
  V = Voltage (Potential Difference)
  Factor = Maximum resistor value (for reverse operation).
  R(A) = 1st resistor
  R(B) = 2nd resistor
  V(R(A)) = Voltage across 1st resistor.
  V(R(B)) = Voltage across 2nd resistor.
Enter Voltage and Resistor 1 and 2 to find the voltage across each resistor, or enter the required voltages and the factor, to find the resistors required for the desired arrangement. 
 
5) Mathematics Calculator
-------------------------
Evaluates mathematical expressions in accordance with Perl.
You can specify how many decimal places the result should be calculated to.
Click on "History / Advanced" to reveal the Mathematics Calculator History and advanced expression/result manipulation.
Use the "Clear History" to delete the entire history, or "Clear Entry" to delete the current history entry.
Use the "Use Expression" to transfer the expression of the current entry to the "Expression" field of the calculator (and the result of the current entry to the "Result" field of the calculator).
Use the "Use Result" to transfer the result of the current entry to the "Expression" field of the calculator (and the expression of the current entry to the "Result" field of the calculator).
Persistent history is saved under $HOME/.sxmtoolkit/fizzyCal/.mCalcHistory

6) Fizzy Pad
-----------
Use for rough work. Open / Save / Save As any number of files you create. Files are stored under $HOME/.sxmtools/fizzyCal with default file $HOME/.sxmtools/fizzyCal/.fizzyPad

7) Colour Codes
---------------
Use as a reminder for color codes on resistors, capacitors and inductors.

8) Relativity Calculator
------------------------
A nice tool.
Remember to enter the speed as a fraction of c, i.e. 0 <= speed < 1

9) Tuning Frequencies
---------------------
6/7 strings Guitar and 4/5/6 strings Bass Guitar normal tuning string frequencies.

10) Frequency Ranges
---------------------
Human audible frequency ranges and their designations.
