    Hi,

    Can somebody suggest me the part to make small voltage, ohm, wattage & battery indicator graphic display everything in 1 screen?

    Maybe something like this:

    is it complicated?

    Thanks

    I believe it's a small OLED display.

    I've seen them used for a number of things that my eyesight is no longer good enough to use!

    It might be something like this.

    If you're planning on using something arduino based, then this might be useful.

    anybody can confirm Adafruit Monochrome 0.96" 128x64 OLED graphic display can display Volt, Ohm, Wattage and battery percentage?

    im totally blank in this. hope somebody can guide me.

    Of course it can't. It's just a display.

    You need to develop (or find) a circuit that can do this stuff and then interface the output to the display. It's all but guaranteed that you'll be using a microcontroller.

    you are not going to measure Ohms directly whilst power is connected ... dunno why you would want to you can easily work it out ... you have the volts and current displayed
    easy enough to work out the resistance of the load

    I have one unit smaller than either of those 2 shown
    have a look at this nice unit :)
    I have it inline to my transceiver radio gear along with one of these protector units an awesome device

    cheers

    Google for the microcontroller used with these things. I've seen it used with arduinos, so that could be a start.
