Social recommendations and mentions

We have tracked the following product recommendations or mentions on various public social media platforms and blogs. They can help you see what people think about Circuit Simulator and what they use it for.
  • I am trying to recreate this circuit in TinkerCAD, which is not giving me the correct current values. What am I doing wrong here?
    Have you tried modeling it in falstad's onine circuit simulator? Source: about 1 year ago
  • How do engineers be confident when printing a PCB?
    Simulation is not viable for all but the most trivial circuits, and even then it won't catch things like a wrong footprint. I do occasionally use the Falstad simulator for simple analog circuits, but that just isn't possible with complicated digital ICs. Source: about 1 year ago
  • How can I derive the equation on the right? Please help!
    I don't know, but you could try simulating the circuit in Falstad circuit simulator to look at what is going on. Source: about 1 year ago
  • ELI5: How to make an electrical circuit that can be switched on and of at specific intervals?
    You can use Falstad to make sure you have a basic understanding of how relays work. Source: about 1 year ago
  • Need recommendations for PCB simulation and printing software
    This is quit comprehensive, but missing the awesome and intuitive online simulator: falstad. Source: about 1 year ago
  • Recommend an easy circuit sketching tool?
    I use for simple circuits. Source: over 1 year ago
  • Help me understand how to read resistors
    The amazing coder at has the fantastic online circuit simulator where you can model just about any electronic circuit you can think of with just about any basic analog and digital part you can think of (no tubes 😢) and watch it run, test voltages and currents at any points while it's running, edit it, and even save the whole circuit as a concisely encoded string that's a part of its own url so you can...

  • How can I make such complicated circuits like you guys??I am still a beginner
    Get a basic breadboard kit with a multi-meter(Or/And go to, and play with basic circuits:. Source: over 1 year ago
  • Trying to find equivalent to transformer 1750T
    Thanks for your responses. I'm doing this purely as a hobby and for learning, I'm just a regular electrician not a component wizard! Oh and btw, I could post my schematic over at falstad simulator online once I've worked out a few bugs if you are interested in looking at it. Source: over 1 year ago
  • Free software tools to simulate and analyze circuits.
    Try this free simulator: It's simplicity is what I like about this simulator. Once you get a hang of the UI, you can simulate simple circuits fairly rapidly. I use it mostly for analog analysis, but it does digital as well. What I most like about this simulator is that whenever you hover over a component, the electrical parameters for that component are displayed. This works for the... Source: over 1 year ago
  • Why does the logic gate work when the resistor is in a certain position?
    I recommend trying out the Falstad circuit simulator -- it's rather cleaner to take pictures of, and also shows you some important things. In specific -- it will show you voltage. Source: over 1 year ago
  • A circuit simulator that doesn't look like it was made in 2003
    There's a similar product at (with an open source core) It's actually really useful, fast, educational. Highly recommended. I also wish someone would revitalize falstad circuit sim (, which is still I think the best tool for experimentation with analog electronics. Just a little bit better interface and user friendliness and it would be amazing! A somewhat more robust... - Source: Hacker News / over 1 year ago
  • pretty please
    This is a simple circuit sim that might meet your needs Source: almost 2 years ago
  • Sziklai Pair Capacitive Soil Moisture Sensor
    Here a similar browser based one I use: Source: almost 2 years ago
  • Share useful website and youtube channel you know
    I would like to recommend you some simulation tools: Http:// Source: almost 2 years ago
  • Simple Light Intensity Indicator
    I'm a longtime fan of Falstad's circuit applet, which runs in a web page. That first link has additional information with the applet up in the corner; a full-screen version is available here. Source: almost 2 years ago

  • Attempting to make an D-latch NMOS-only circuit. I have gotten individual gates to work on a breadboard but everything falls apart as I add more gates. I believe it's because I'm failing to understand the correct orientation they need to be in. Also, only one pull down resistor is necessary correct?
    You could try using a simple simulator to help see what the issue is Http:// Source: over 2 years ago
  • Would this tank oscillator circuit work? If not, why? Dont call me an idiot, I'm 15.
    There is also the Falstad simulator that is a bit more user friendly. Source: over 2 years ago
  • Controlling RGB LEDs with only powerlines: Anatomy of a Christmas light string
    You can always play around with the simulators - Source: Hacker News / over 2 years ago
  • Water circuit analogy to electric circuit
    Https:// One issue with the hydraulic/fluid analogy is the "empty pipe" misconception - we forget or don't know that in electrical circuits, the circuit is a closed loop. The Falstad simulation shows a line of moving dots that move faster or slower depending on the current - a little more like a train moving in a pipe. - Source: Hacker News / over 2 years ago
