  • Recommend an easy circuit sketching tool?
    I use for simple circuits. - Source: Reddit / 24 days 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... - Source: Reddit / about 1 month ago
  • 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: Reddit / about 2 months 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: Reddit / 2 months 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: Reddit / 2 months 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: Reddit / 3 months 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 / 4 months ago
  • pretty please
    This is a simple circuit sim that might meet your needs - Source: Reddit / 6 months ago
  • Sziklai Pair Capacitive Soil Moisture Sensor
    Here a similar browser based one I use: - Source: Reddit / 7 months ago
  • Share useful website and youtube channel you know
    I would like to recommend you some simulation tools: Http:// - Source: Reddit / 8 months 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: Reddit / 8 months 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: Reddit / 12 months 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: Reddit / about 1 year ago
  • Controlling RGB LEDs with only powerlines: Anatomy of a Christmas light string
    You can always play around with the simulators - Source: Hacker News / about 1 year 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 / about 1 year ago
    Hi, I don't have the time right now to explain, but here is a circuit simulator that I use a lot. Https:// - Source: Reddit / about 1 year ago
  • Need help to get the correct voltages in my H bridge circuit.
    Im trying to make a H bridge circuit for a dc motor (2.5-6V and around 25 ohm) with a 9V source. I want it to be controlled by turning the switch on or off, but with the voltage of the source I cant make both the motor and MOSFETs have the correct voltage. I've used (mostly in norwegian) as a circuit simulator to see the voltages around the circuit and I get approx 2.8V at the motor... - Source: Reddit / about 1 year ago
  • Help needed choosing ICs to simplify an analog frequency shifter
    It may be worth it to simulate the circuit, although this simulator mostly uses ideal components. - Source: Reddit / over 1 year ago
  • One schematic of many. More to come
    It is a schematic run in that pulls charge from the ground of the circuit. - Source: Reddit / over 1 year ago
