Mac-Friendly Keyboard Shortcuts

Good news! The CircuitLab editor now supports the use of the Command key for the common keyboard shortcuts instead of requiring the Control key.

We want CircuitLab to feel as much like a desktop application as possible for all of our users, so since launch our programmers have been working to resolve a few of the issues Mac OS X users were encountering with our interface. The keyboard shortcuts for Copy, Cut, Paste, Undo, Select All, and Save can now be triggered by using the Command key, which should feel more natural for Mac users instead of having to reach for the Control key.

In addition, panning around a circuit can now be done with Command + mouse drag, instead of using Control + mouse drag which will trigger a right click menu on Macs.

Mac users can also now delete selected items with the Delete key on their keyboard.

Keyboard shortcuts for Windows and Linux users should remain unaffected. Check out the updated full list of keyboard shortcuts.


CircuitLab Launches!

We are happy to announce the launch of CircuitLab, the first web-based circuit simulator with the power and accuracy needed for board-level design tasks. CircuitLab is now available free of charge to practicing electrical engineers, engineering students, and electronics hobbyists around the world.

CircuitLab is completely web-based, which not only means it’s cross-platform (Windows/Mac/Linux) and requires no installation or plug-ins, but also means that all the circuits you choose to make public can be shared by just copy & pasting a URL!

In addition to being a great tool for learning and experimenting, CircuitLab can also help you answer everyday questions that come up when building circuits, like:

  • if I use my microcontroller’s digital PWM module for audio output, how will my low-pass filtering affect the signal before it goes into my speakers?
  • is my 1N4148 diode good enough to clamp the inductive voltage spike from my solenoid?
  • … and if not, how about the 1N5817?
  • what’s the bandwidth for this TL082 op-amp as a gain-of-100 inverting amplifier?
  • … and when I put a BJT push-pull output stage after it?
  • can I build a simple LED current regulator using a LM317 adjustable voltage regulator?
  • … and can I do it using just one transistor instead?

Take a look through our example circuits to see more of what CircuitLab can do.

Looking forward to hearing your feedback on the support forum!
