Hi, I have seen the merge request, just not managed to reply to it yet. Lately most discussion has been on the ktechlab-devel mailing list at KDE, I suggest using that: https://mail.kde.org/mailman/listinfo/ktechlab-devel

Similar question, where the discussion regarding this project can take place now a days? I have an MR toward the ktechlab repo at: https://invent.kde.org/sdk/ktechlab and planning to contribute more.

Hi, Related to the points above: 1/ I'm not sure if I can reproduce this behavior. Can you send a screenshot about it? 2/ The scope display has been initially conceived to run continuously; currently it displays probe data from a limited amount of time and then stops; the Reset button is there to discard the old data... In my opinion the Pause / Run buttons for the whole simulation are good enough. 3/ The microcontroller functionality depends on the gpsim library. Only if development files for that...

I've just managed to get ktechlab built on the latest version of Linux Mint using KDE Craft. On Windows 10 there was a problem with not having Python 3.9 installed (I have a newer version installed). The Linux installation was simpler. Are there any VERY basic things that a total beginner in QT development could help with? For instance I've noticed a few things 1/ F10 seems to be reversed. The tooltip says "PAUSE" when the simulation is actually paused and "RUN" when it is actually running. This...

Copying the response from the mailing list, for future reference: Hi David, building KTechLab on Windows requires KDE Craft, please see instructions here: https://community.kde.org/Craft https://community.kde.org/Guidelines_and_HOWTOs/Build_from_source/Windows There exists a Craft recipe for KTechLab, so in case Craft is set up, one can build KTechLab with one command. On Linux systems building is much simpler, you just need to install KTechLab's build dependencies, typically from package manager,...

Hi, I would like to build Ktechlab on Windows 10. I have QT Creator 8.01 installed but Ive never used it. Maybe this would be an opportunity to use QT. Do you have any build instructions I can follow? I also have Linux Mint 21 "Vanessa" installed and could build it on there as well. Which would be the most straightforward one to build on? Thanks. Regards, David, UK

You are correct, the LED (and Diodes, in general), does not have constant resistance. In the example circuit you are practically connecting in parallel two components with try to keep a constant, but different voltages on them. In a real-world circuit, either the LED or the voltage source/battery would get burned. Please note that for such extreme cases (when you see Mega-Ampers or Mega-Volts or higher in the circuit), probably ktechlab does not simulate the circuit accurately.

In case anyone else is having the same confusion I found an explanation for this. https://electronics.stackexchange.com/questions/76367/accounting-for-led-resistance/76372#76372?newreg=ae8bec16116449b38b8b3f548d004072 Turns out LEDs do have a voltage drop but not a constant resistance like resistors. Instead they tend to keep the voltage drop stable. That's the reason when the resistor is 1 microOhm the LED also seems to have almost no resistance and the total Resistance becomes so small that the...
-
Also when I think about it, the total resitance on the circuit is so small that the ammeter's resistance may have been taken into account. However that is the least of the problems I have. The main thing that concerns me is that the led has next to zero resistance. This almost makes sense to me since it's a diode but I don't think that is the case with real LEDs

2017-05-28 18:01 GMT+02:00 timucin toraman@users.sf.net: When I connect an LED and an Ammeter serial to a 9V battery, the Ammeter shows 13.2 kA. If I add a 1 nanoOhms resistor serial to the rest, the Ammeter shows 4.06 MA. Also the LED has 1.29V between each side and the resistor has 4.06V which doesn't add up to 9V. A battery has an internal resistance and this should be what you're seeing here. I don't have a working installation of ktechlab but there should be a way to tweak the resistance or...

I tried to tweak the LED but the properties I can adjust are breakdown voltage, color, emission coefficent and saturation current none of which seems to change the readings on anything. Normally a 9V battery, a standard LED and a 300 Ohms...
