My electronics projects have gotten complicated enough to give me a headache. To surrender to this complexity I started using a circuit simulator application. The one I downloaded is FREE and seems pretty good. It is called LTspice (spice stands for Simulation Program with Integrated Circuit Emphasis). The program is available for download by anyone at: http://www.linear.com/designtools/software/.
I also found a Java-based program available as a web applet here for very simple things: http://www.falstad.com/circuit/
