CircuitLab Launches!

Feb 27 2012, 7:00 PM PST · 5 comments »

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!

Congrats!

This is definitely something I will be using all the time.

I am so impressed with this. I will be using this for all my pre-prototyping for my Arduino projects.

Where was this 15 years ago when I needed it. PSpice? Not for me anymore...

Seriously a pretty amazing Spice and great execution.

Yep. This is my official replacement PSpice.

You guys are great; I asked my ECE professor to spread the word.
