    AC circuit (120v single phase) smooth to a10 sec. average voltage sine wave

    Yes it would change it to DC. So you dont want to measure anything then. I think what your after is a mains filter. Adam

    Nope, thats a bugger, still no clues for me. Adam

    One has 3 legs, looks like a Microchip part.

    AC circuit (120v single phase) smooth to a10 sec. average voltage sine wave

    Diode and capacitor, basically a rectifier, but you lose a diode drop. If this is not ok the a absolute value circuit would be used.

    AC circuit (120v single phase) smooth to a10 sec. average voltage sine wave

    Yes your right, but the average of a sinewave is taken over half the period :) because over a full cycle as you said is zero. Adam

    Convert it to PNG, thats normally small enough.

    AC circuit (120v single phase) smooth to a10 sec. average voltage sine wave

    An integrator will do this for you. A simple diode and RC network. Still not sure what you want to do. Adam

    AC circuit (120v single phase) smooth to a10 sec. average voltage sine wave

    Hi David, who told you the average of a sinewave is 0? No I am not mad......

    AC circuit (120v single phase) smooth to a10 sec. average voltage sine wave

    Hi David. What do you mean 5 - 10 second average? Please explain what you are doing. Thanks Adam

    Easy. Take Pic, compress it to 100Kb save on your PC. Goto upload file in the thread box you are typing in. Its down the bottom. Click full image, job done.

    PWM solenoid use

    Good answer from Fish. If you don't have the ability to program a micro controller you could possibly do this with a triangle waveform generator and a comparator. Or an astable oscillator with variable mark space ratio. Thanks Adam

    Don't throw them away just yet, someone else might know what they are! Adam

    Packages like this could be a number of components like a varactor diode, reference diode of SIDIAC. Couldn't find anything either with the device numbers you gave. Sorry. Adam

    PNP NPN combination switch for low water level alarm.

    Hello The 500 Ohm resistor is too low and will hold the transistor off. You will only have approx. 230 mV across the base and emitter terminals, this is not enough to fully turn on the transistor. Remove the 500R and see if that works. Adam

    Hi Would you say this looks the same size as a TO-92 type signal transistor or is it much larger? Adam

    Slow blow or fast blow fuse?

    That's true Jim. You could take the unit apart and post some pics of both sides of the PCB here, and let us have a look. We might see something. Thanks Adam

    Slow blow or fast blow fuse?

    Hello Yes I would have thought SB meant slow blow. If you still have the original fuse it may have some markings on it that tell you what type it is, that's if it is the original and someone hasn't replaced it with the wrong type. Some slow blow fuses will have a T at the end of the rating, to...

    LED sign help

    Hello mortyBox Can you explain how the circuit is supposed to work? Or how you want it to work. Thanks Adam

    What's the difference between copper/brass power plugs and nickel plated ones?

    Can you take a picture? And show us the unit you have. Adam
