Hobbyists... Technicians... Radio Amateurs... Students... Engineers! Solve basic electrical and electronics formulas quickly and easily with the Electronics Toolkit!
From simple Ohm's Law calculations in direct current (dc) applications to complex design equations for alternating current (ac) and radio frequency (rf) circuits, the Electronics Toolkit can help anyone solve basic electronics
formulas quickly and accurately.
Based on an Excel® workbook format, each section is easy to use and is organized around traditional electronics topics such as Ohm's Law for a.c. and d.c., series/parallel circuits,
capacitance, inductance, resonance, time constants, and much more.
Containing over 160 of the most often used calculations in electrical and electronics applications, the Electronics Toolkit is a ready reference tool for anyone working in the electrical and electronics
fields.
 Amateur Radio
 This handy CD assistant has all the basic formulas for developing that next circuit, verifying basic dimensions for a weekend antenna project, or designing the rf section of a QRP transmitter. There may be other sources for this data (handbooks, formulas programmed into a calculator, etc), but the
Electronics Toolkit has all the basic formulas available for ready calculation in an easy to use Excel workbook that includes 'units' conversion by input and output
variables. For example, if the capacitance of a parallel tuned circuit is in pF, the inductance is in mH, and you want to know the resonant frequency in mHz, just select these units in the drop down list for each input variable
and the value of the resonant frequency in the output cell will be adjusted accordingly.
 Electrical Engineering  The Electronics Toolkit can be used initially to introduce students to
electrical engineering principles and later as a reference for electrical engineers practicing in the field.
 Technical Colleges  The organization of electrical and electronics formulas in separate worksheets in the Electronics Toolkit
follows closely the arrangement of topics and chapters in many text books. Consequently, the software can be used as a teaching tool alongside the text book in the classroom as well as the lab. Later, when the student graduates, the
Electronics Toolkit will serve as a reference and a refresher of all the basic electrical and electronics formulas.
 How To Projects  Whether you are an electronics enthusiast, experimenter, hobbyist, or DIY enthusiast, the Electronics Toolkit
has all the basic formulas you need at your fingertips for most electronics projects.
 Broadcasting  The Electronics Toolkit
can be used in preparation of the FCC licensing exams which often require basic calculations of various electronics formulas. For example, the following is a typical question from an FCC exam: In a parallel tuned circuit composed of an inductance of 200 uH and a capacitance of 200 pF, what is the resonant frequency? The solution to this problem can be easily solved by the Electronics Toolkit which also provides additional information to assist in learning the principles.
 Industrial Electronics  Technicians will also find the Electronics Toolkit handy in
troubleshooting and maintaining electronics equipment in a variety of applications.
Here are some typical applications for the Electronics Toolkit
Five Benefits when using the Electronics Toolkit
What People Are Saying About the Electronics Toolkit
Each subject area in the Electronics Toolkit is organized into a separate worksheet which includes the following features/advantages/benefits:
 Basic definitions are included for reference purposes
 Input and output variable fields include a choice of units where appropriate
 Actual formulas used in the calculations are displayed for ready reference. This is a distinctive feature that sets the Electronics Toolkit apart from many of the other products
on the market. The user can apply the calculation with less guesswork and greater confidence in the results.
 Where appropriate, additional diagrams and application notes are included to assist the user.
 The Electronics Toolkit is an 'open' application model that can be expanded by the user to include customized calculations and notes.
 Easy to Use
 The spreadsheet format does not require installation in your computer, so you can put it to work at any time on any PC running Excel. All calculations are conveniently organized into separate worksheets and are easy to locate and apply. Each worksheet can be printed out for documentation or future reference.
 Cost Effective  At only $29.95, the Electronic Toolkit
is one of the most cost effective products on the market.
 Convenient
 Take the CD with and use it anywhere on any computer running Excel. Also, the spreadsheet model means that the software is totally open, nonproprietary (so the user is free to customize the calculations, add worksheets, or include additional notes as desired).
 Saves Time
 All key electronics formulas and calculations are compiled in one handy CD (there is no need to hunt around for a handbook with formulas that must be entered manually into a calculator).
 Simplifies Your Work
 While there are other products on the market, the majority are DOS based and must be installed to run. They also only allow one set of units (so you are forced to convert input data prior to entering it into the program). Usually, the DOSbased programs do not display the formula used in the calculation, so you are never sure of the results. On the other hand, the user friendly interface of the Electronics Toolkit simplifies the formula calculation process so you can concentrate on solving the design or the troubleshooting process. With the formulas clearly displayed, you can be more confident of the calculated results.
Very professional and impressive...I liked the PDF documentation with the easy contents worksheet.
 Louis B., National Electric Power Industry Consultant
I liked the fact that no installation is required and also the innovative use of Excel® macros and the PDF
documentation.

Glen L., USAF Lt. Col and Amateur Radio Operator
This product is very attractive  it looks as good or better than any other program I have seen...anyone who uses the formulas
would find the Electronics Toolkit very useful. This is a first class product, very well arranged, easy to use, and valuable to anyone in the field of
electronics.  Leroy B., Retired Electric Utility Engineer
This is an outstanding product, very hitech and appropriate for anyone in electronics. I particularly liked the ease of navigation and the graphics.
