Have you ever wanted to try out a circuit conceptually on your computer to see if your idea would work?
Have you wondered what would happen if you made a change or two to an existing design before you committed to making the mod or buying the parts?
Have you ever wanted to design something from scratch but wished for a way to check it?
All of this is possible and for free! All it costs is a small download and a simple one-click install.
When I came across LTspice and learned that it also works with circuits graphically (with schematics), I knew I had to learn it. Even though it is a graphical and friendly tool, it still took me some time to learn the ins and outs of it. There are a few pitfalls to avoid and I'll save you time pointing to things you'll want to know.http://www.experimentalistsanonymous.com/ve3wwg/ltspice_main
These tutorials will get you up and running immediately in step by step fashion. I have put a lot of effort into these tutorials because I believe LTspice is just too useful not to share. I also believe it is such a great tool for those learning electronics! Prove simple things like ohms law or do more complex things like opamp design. LTspice is not cripple-ware. It is the full deal.
There's nothing in this for me (I'm not selling anything). I just believe that if you were to start using it today, you'd start benefiting immediately from it electronic-wise.
The best thing about it is that you don't need parts, you don't need a breadboard and you don't need an expensive oscilloscope (it's built-in to the software). If you're reading this from your computer, you already have what you need.
There are more LTspice tutorials planned. But take advantage of what is already there to get yourself started.
