New 2014: Free electronics and IT vocational interactive training.  This tutorial uses all my e-books, Labs, and links to create full course curriculum.  Click here to start learning now!

Virtual Circuit Kits:
Get Kits 3 and 8 Beta versions Free : Click Here for download 
Kits Contain Resister Networks, Wheatstone Bridge, Ammeter, Capacitor Circuits, RLC(Resistor, Inductor, Capacitor Circuits, and Complex filters.  Lots of faulty circuits included for troubleshooting.

Also Included as part of our Free System Troubleshooting learning method are:

1. Meter Math (Click here)    Troubleshooting Numeric Systems.

2. JavaScript for scientific Calculations (Click here) I teach you how to program and perform electronic calculations simultaneously. 

3.  Electronic Concepts our  best free e-Book (Click here)  For engineers and technicians.


The Internet provides you with all the graphics and text about electronics that one can imagine.  My site and e-books are special, because they provide not only free books, but the books include FREE virtual circuits to observe and troubleshoot.  You get virtual circuits with out the expense of Brick and Mortar bread boards.  Industry does not need technicians that have simply read about electronics circuits, that is why electronics schools have laboratories in addition to classrooms.  I provide laboratory manuals combined with virtual circuits for you to troubleshoot. That makes this site and its free downloads different, if not uniquePlease bookmark my site  and download some or all of my free e-books and simulations.
