Circuit Simulations - Rodney Hills

Sorry, you need a Java-enabled browser to see the animation.

This java applet is an electical/electronic circuit animator. When the applet starts up you will see an animated schematic of a very simple circuit. The green colour indicates positive voltage. The grey colour indicates ground. A red colour indicates negative voltage. The moving yellow dots indicate current. See the options pull-down for display control settings.

To turn a switch on or off, just click on it. If you move the mouse over any component of the circuit, you will see a short description of that component and its current state in the lower right corner of the window. To modify a component, move the mouse over it, click the right mouse button (or control-click if you have a Mac) and select “Edit”.

The "Circuits" menu contains a number of sample circuits for you to try. The circuits presented are mainly from the sphere of model railways. Documentation about these, plus artwork for additional circuits, is in course of preparation by the site collator, Rodney Hills.

I am grateful to the various circuit designers who have given me permission to publish their work in this format. The original author's documentation should always be consulted for further details about their circuits. Some of this documentation will only be accessible to members of MERG, the "Model Electronic Railway Group".

If you don't have Java, get the Java plug-in.

Directions.

My Circuit Animator is a modified version of Paul Falstad's Circuit Simulator applet and you are strongly recommened to visit Paul's site, e.g. his pages:
