tkCybernetics project is a lightweight cybernetics simulator.
It was designed for didactic purposes, but might be useful for quick tests of circuits.
- The usual elements (all apropiately parameteryzable) are available - highpass filter, lowpass filter, integrator, sums, characteristics, completely customizable functions, factors, input-functions and output at arbitrary points of the circuit.
- The results are displayed as graphs and can be exported as postscript. Does currently not support saving of circuits. Checks if circuits are logicaly correct. It's NOT intended for simulation of artificial neural networks or really complex siystems. It's extensible, but only if you know Tcl (and know it well) - port to Python considered.
