Create Circuit Simulations on your Phone with iCircuit

iCircuit is an easy to use circuit simulator and editor on your iOS and, recently, Android phone. It's a perfect tool for engineers, students, and hobbyists who are on-the-go and need a quick look at how a circuit works.

As the creator said,

The app features a multimeter that you use to probe around the circuit to instantly read voltages and currents. If you want to see how a value changes over time, then you can add values to the built-in oscilloscope. The scope can simultaneously track many signals over time and features a touch interface to control the total time displayed and stacked and unstacked modes to easily compare signals.

Basically it's a simulator built for studying simple electronic circuits or a component.  Touching a component will display an oscilloscope to see what is happening on the waveform at that component. I've used this once to show how a power supply works - rectification, filtering, regulation.

Supported elements include:
  • Signal generators, Voltage sources, and Current sources
  • Resistors, Capacitors, and inductors
  • Manual SPST/SPDT Switches, and SPST/SPDT relays
  • Diodes, BJ Transistors, and MOSFETs
  • Speakers, Buzzers, and LEDs
  • ADCs, and DACs
  • Logic gates: AND, OR, NAND, NOR, XOR
  • JK and D Flip-flops
Its also loaded with sample circuits to see the app in action

iCircuit is really a handy app so try it out yourself!
