(Obviously you will need the Java plugin to run it)
What really sets this one apart is that it visually models the electrical flow along the connecting wires – so it really makes it obvious how the circuit will behave.
If you are new to electronics this is an absolutely brilliant way to learn what transistors, diodes, gates and op-amps do.

Here’s another great prototyping product:
Great stuff!
