Sketch, simulate, and share schematics in browser

Imagine tool to create and share schematic right up in your browser, sound great. Off course it is a great idea. Recently I came across CircuitLab an alternative schematic tool. Long back I encountered similar site “Upverter:”, though this one is miles ahead in offering. It is very simple to use, create your account which is off course free and then create circuit in the browser save it. Great thing is you can share your this links with your friends or expertise.

For now it is free, but there are indications that they might charge you in feature. CircuitLab  allows real-time circuit simulation using models similar to SPICE, a popular desktop simulation package. Testing your circuits as you create them is a huge advantage, and if there’s any other online tool that allows this, at least I am unaware of it.

For Students & Educators

Draw and print beautiful schematics for lab reports. In-browser simulations make it easy to quickly learn electronics concepts via just-for-fun playing and guided exploration. Our tools complement undergraduate and graduate electrical engineering classes, as well as high school and college physics curriculums.

For Hobbyists & Tinkerers

CircuitLab lets you rapidly test circuit ideas before breadboarding. And when we host your circuit, we provide you with a convenient image and link that you can use to share your circuit on online forums or your own website, so you can contribute to or get help from the hobbyist community.

For Practicing Engineers

Our user-friendly schematic capture tool lets you explore the design space in a fraction of the time of traditional tools. SPICE-like models with a mixed-mode simulation engine help you apply one tool to a wide range of design tasks, from digital to analog, DC to VHF and beyond.

Following are few features circuitLab claimed on their site:

  • Easy-wire mode lets you connect elements with fewer clicks and less frustration.
  • Cross-window copy/paste lets you easily explore and re-mix parts of public circuits from the CircuitLab community.
  • Mixed-mode circuit simulation lets you simulate analog and digital components side-by-side.
  • SPICE-like component models give you accurate results for nonlinear circuit effects.
  • Human-friendly formats let you enter and display values concisely, just like you would on a paper schematic.
  • Unit-aware expression evaluation lets you plot arbitrary signals of interest, such as differential signals or power dissipation.
  • n-browser simulation and plotting lets you design and analyze faster, making sure your circuit works before ever picking up a soldering iron.
  • Unique circuit URLs let you easily share your work or ask for help online.
  • Advanced simulation capabilities include frequency-domain (small signal) simulation, stepping circuit parameters through a range, arbitrary Laplace transfer function blocks, and more.
