Nice LTspice tutorial

It is a great program, and I just updated to the latest version. I've = used=20 it for a long time as my primary simulation program, and it's great for=20 sharing circuits on newsgroups using the ASCII files. There are some = things=20 I am not too familiar with and a tutorial such as this is valuable.

I also received an email about an upgrade to version 9.x for my other=20 simulator, TINA.

I purchased the basic version 6.0 quite a few years ago, and it has some =

cool features. I like the animated interactive controls such as LEDs = that=20 light up and switches that can be controlled by a mouse click. It also = has a=20 PCB layout feature and 3-D views of PCBs with components.

Texas Instruments has a limited free version:=20
