Functions

See tricks page for some hints on how to use MiscEl
• System  Prefered components Select component values used in all designs and step size for ctrl-n and ctrl-m Hotkeys Define hotkeys for opening pages
• Miscellaneous  Geometry Handles: Circles, part of circles, triangles, squares, rectangles, trapezoid Sound Sound speed and perceived sound levels Weather and air %RH, dewpoint, air pressure and other weater releated calculations Periodic table A periodic table with all elements, it has search functions and a few data for each element Photo lens Some lens calculations Photo light Some light calculations
• Calculations  Calculator Can do all the usual stuff, including mathematic. TinyCalc Can do the same as the entry line in Calculator, but is very small when pulled out. Curve fit Fits a curve to a collection of data points Ohms law Ohms law, impendace of capacitor and inductors, complex power Ohms law 3 phase Ohms law with complex power for 3 phase systems dB Decibel and neper, both power and voltage including volt/watt for a reference level Charge curve Capacitor/inductor charge/discharge with resistive, current and power loads (not all combinations supported) Waveforms Calculates RMS, mean, PEEK, DC, FFT for different waveforms.
• Mechanical  Wires Calculates resistance and power loss in wires, can also do conversion between USA and european units. Cable calculations Calculate frequence response of a cable Fan cooling Calculates how big a fan to get rid of some power. Heatsink Calculates junction temperature for specifed power level and heatsink Printed circuit board Calculate microstrip, stripline, track resistance and current Cable calculations Simulate cables at low (audio) frequences
• Components  Capacitor design Calculate capacitance of different geometries Color codes Convert between color codes and numeric values for many types of components. Thermo sensors Calculates for PT100, NTC and all types of thermocouples Air coil Analyze or design an air core inductor Leds Color/wavelength of leds and design of circuits to drive leds from DC or AC. Components type numbers Tries to decode component codes Power MOS Turn on/off time and power loss estimation
• MPU  MPU Timers Calculates divide factors for up to five software timers Integer math Converts real numbers to fractions, calculates primes and other integer stuff Serial communication Timing and curves, usefull when programming software uart's and IR rx/tx. CRC and checksum Calculate crc, checksum and modulus for datablocks, can also analyze a datablock for what checksum/crc was used
• Simple Circuit  Fo Calculates Fo for RC, RL, RLC circuits Series/parallel Calculate/design series/parallel connection of resistors, capacitors and inductors Charge time Charge/discharge time for simple circuits (including 555). Voltage divider Design/analyze voltage dividers, can include component tolerance and load. Two port Conversion between different types of two ports.
• Circuit  1. order filters Analyze and design 32 different filter configurations Attenuator network Design different kind of attenuators Power Supply Analyze and design power supplies with 78xx and LM317 style regulators

Some screen dumps from MiscEl

Installing

The program will automatic install first time it is run, this can be disabled by putting "noinstall" on the command line.

A few notes about the program

• Right click to get a menu (Works on most pages).
• If no other unit is specified then input fields are for basic SI values (meter, ohms, volts, etc.)
• It is possible to use SI-prefix after numbers, i.e. "10k" is a legal value
Be carefull with "10m" and "10M" the first is 0.01, the second is 10000000
• All input fields can do calculations.
• Red fields means error in input.
• Pages can be dragged outside main program, making it possible to view more pages simultaneous.
• Use Ctrl-N and Ctrl-M to step values.
• Remember to use "System, Prefered components" to set standard values (and step sizes).

Command line options for MiscEl

• -last Do not restore open pages from last run
• "pagename" Open this page, spelling must be with correct case. This option can be used multiple times
• noinstall Do not try to install MiscEl, just run the program from the current location
• -key{keyname} execute the hotkey definition for specified key i.e. "-keyF10" will execute the definition for F10
