iCircuit 1.4.6 for iOS Released

iCircuit 1.4.6 for iOS was released today featuring improved circuit simulator code to speed it up on modern hardware and a bunch of bug fixes.

This is a compatibility upgrade to make sure it works well on iOS 6 and the iPhone 5. New features will be coming in v 1.5, but I wanted to make sure this version got out before then.

Update There was a bug introduced in this version that causes "Singular Matrix" errors to be displayed on iOS 4.3 devices. This bug has been fixed and new version (1.4.7) was sent to Apple on Friday, Sep 21. I am very sorry for this mistake and appreaciate your patience while we wait for approval.

iCircuit for Android Released

I am very pleased to annouce that iCircuit has been released for the Android platform!

There has been great demand for this version and am thrilled to be able to support the millions of Android users throughout the world.

The Android version has all the same components as the iOS version but also has a few new and exciting user interface enhancements. Tak a look at the dial for inputting numbers, and the mini-scope at the top of the screen. These enhancements will soon be coming to iOS in V1.5!

iCircuit 1.4's New Features

iCircuit 1.4 was released and has some powerful new features.

• Dependent Sources let you specify mathematical expressions for voltage and current sources. These expressions can reference other elements allowing you to solve some of those annying homework problems and simulate complex models.
• Subcircuits allow you to modularize your designs and create custom elements. (Combined with the dependent sources, this is a very powerful new feature.)
• Custom Scope Tracks allow you to perform and plot math on different signals in the circuit.
• Scope Triggers make it easier to analyze high-frequncy or frequency-varying signals.

I am very excited for these new features as they greatly extend the power of this app. I hope you enjoy them as much as I do!

Oklahoma Robotics is using iCircuit

Oklamhoma Robotics, a freelance electronics engineering firm, is using iCircuit in their initial prototype designs. While iCircuit is focused on students and hobbyists, it's quite gratifying to see it used by engineering teams!

New Dependent Sources

Dependent sources are coming to iCircuit. They don't really exist of course, but their pervassiveness in textbooks has made it difficult to use iCircuit when in early college courses. No longer! You will now be able to use iCircuit's engine to help you through this pesky homework problems.

For instance, here's Problem 13 from Chapter 2 of Engineering Circuit Analysis.
