    LTspice, Warning node is floating

    Got it working but it takes ages to simulate. You had a label for 12 Volts but didn't have a voltage source :) Delete the 12V label from the output and add a 12 Volts source to your switching regulator. Thanks Adam

    LTspice, Warning node is floating

    Just woke up, got a few things to do. I will have a look later, if @Harald Kapp doesnt beat me to it :) Adam

    LTspice, Warning node is floating

    Can you post the .asc file and library files for the non standard parts and I'll have a look. You can zip them up and add them as a file. Adam

    LTspice, Warning node is floating

    Hi Trevor That's just a power net label I think, how is it floating? Adam

    Help $ home work.

    You can not work this out exactly. You can measure it with test equipment but that's all. If you have the datasheet for the LED you will get close but not exact. Thanks Adam

    How to create a muting stereo mixer?

    The level could be as high as 2 Volts, depending on the volume adjustment. You don't need software to do this. Adam

    I think I had one eye shut while picking my nose sweet pea!

    How to create a muting stereo mixer?

    When you say higher than zero, do you have a particular lower level in mind or is this line level voltages? Adam

    IR and Photodarlington circuit doubt

    And the difference in timings?

    12v Battery Charger Circuit with Auto Cut off

    Pin 5 is the inverting terminal of the 555s internal comparator. I think what they mean is that it's related (connected) to the TH pin which is the non inverting terminal of the comparator which just happens to be more positive than the CV pin. Adam

    IR and Photodarlington circuit doubt

    I can't see your images? How much of a change in IR levels are you expecting to see? What difference in signal propagation are you expecting to see, I bet it's very small. Adam
