  • PCB Tracer
    I needed exactly this sort of tool for a reverse-engineering project! I was so invested I returned here to write this comment... Then spotted the other comments about "no Firefox support". Indeed, visually broken "Browser Not Supported" popup appears. Darn. Disappointing. Guess I will have to keep looking. Also... It doesn't look open-source and the comments about file access are valid. The functionality listed is... - Source: Hacker News / 5 months ago
  • 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 3 years 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 3 years 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 3 years ago

    Get a basic breadboard kit with a multi-meter(Or/And go to Falstad.com), and play with basic circuits:. Source: over 3 years 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 3 years ago
  • Free software tools to simulate and analyze circuits.
    Try this free simulator: falstad.com/circuit/ 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 3 years 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 3 years ago
  • A circuit simulator that doesn't look like it was made in 2003
    There's a similar product at https://wokwi.com/ (with an open source core) It's actually really useful, fast, educational. Highly recommended. I also wish someone would revitalize falstad circuit sim (http://falstad.com/circuit/), 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 3 years ago
