• An open source, educational, low-cost modern analog computer

  I have used https://openmodelica.org/. It's another one of those "invest substantial time understanding what they are doing, and you will likely be rewarded." Simple things are simple, but I found it took longer than I would have like to bang out e.g. a PID algo with a particular motor and load. If you want to try this, buy the book, and follow it to the end. Then keep learning, as you build more and more... - Source: Hacker News / 11 months ago

• Best software for parallel robot simulation?

  If the robot simulation doesn't need to pick up stuff or take into account changing contacts with other objects you can use Modelica's Multibody library which you can run for free with OpenModelica. This will be more accurate than other simulators because modelica can analytically solve the dynamics equations. You don't need to write them either just to connect blocks for various components.

• Anyone know if python can be used to make a MATLAB simulink clone (dragging and dropping elements)? If not, do you have recommendations of other languages that can do this best to make a desktop app?

  OpenModelica consists of a combination of graphical and written components to simulate dynamic systems. I don’t know what control system feature set might be available. AMESIM is a more extensive paid tool that operates on the same Modelica modeling language. IIRC, at least Simuscape operates on Modelica under the hood. Source: about 1 year ago

• Just introduced to diffeq last year. Curious how to go about modeling something like this.

  It shouldn't be too difficult to model in Modelica. You could approximate the pendula in 1D with masses on springs or just use Modelica's multibody library. Source: about 1 year ago

• Need software recommendations please

  Modelica is a good start, at the very least in showing how to break a complex machine with many physical phenomena into components. Modeling accuracy and ease are generally opposed. Https://openmodelica.org/. Source: almost 2 years 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: 10 months 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: 11 months 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: 11 months 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: 12 months ago

• Need recommendations for PCB simulation and printing software

  This is quit comprehensive, but missing the awesome and intuitive online simulator: falstad. Source: 12 months ago
