    Reid,

    Thanks for the measurements!!! The height and width of my frame design aren't far off the mark at all so it should be real easy to adjust the design for a nearly perfect match. Regarding the label positions, I think measurements of the openings in the back of the face plate would work best. That will allow me to match the horizontal spacing of the LED mounts to the label positions.

    Again, Thanks!

    Reid,

    Any chance you were able to get those additional measurements for the label positions? I'm hoping to squeeze in a few build hours this weekend. The work schedule is nuts so haven't had many hours on the pit build in the past week or two.

    THANKS!!!!

    Re: Cessna 172 Annunciator Panel

    Thanks for the reminder Tom.

    Here goes:

    The total width of the indicator assembly is 3.52"
    display edge to edge is 2.74" centered in the 3.52"

    Height of the letters in both rows is.24"
    The wall between rows is .036"

    Hope this makes a little sense. Bear in mind that this is measured from the back, so the order will be reversed looking at it from the front.


    Top Row widths
    ---------- line width1.25"
    wall between ---------- and R indicator(for fuel) .04"
    R indicator = .238"
    wall between R and LOW FUEL= .028"
    LOW FUEL width= .80"

    Bottom Row widths

    VOLTS Width=.725"
    wall between VOLTS and R (VAC)=.045"
    R Indicator=.244"
    Wall between R and VAC=.016"
    VAC display=.430"
    Wall between VAC and L =.022"
    L indicator=.241"
    wall between L and OIL PRESS=.015"
    OIL PRESS width = .993

    If you are trying to recreate this in life size, I may be able to scan the front plate and email it to you so that you can get the proper font/spacing, etc. Might be easier than decoding this stuff.

    Thanks for the dimensions!!!! A full scale scan of the face plate would be perfect! Thanks!

    I'm hoping to build the circuit board and LED mounting frame this weekend and start to figure out the face plate.

    Re: Cessna 172 Annunciator Panel

    Tom,

    Will get to work on that for you. Have discovered some neat stuff re: the panel.

    According to the 172r information manual, the indicators should all blink on the annunciator for appx 10 seconds before going steady on. Not sure how to do this in fs2p, but will work on it. I also have actual numbers the real thing uses before lighting, instead of the ones I figured out through trial and error.

    Do you know when and why the "--------" section lights up?

    I built the configuration using FS2P 5 with a combination of trial & error and some googling, but don't recall if I used actual specs or not. If you have the real numbers that would be cool.

    As for the blinking, I suspect with a bit of experimentation we could figure out how to do that in FS2P. I'll start poking around with that and we'll have to compare notes.

    As for the the bar lighting up I really had not given that any thought. I was just mimicking what I saw in FSX and didn't pick up on anything specific.

    My phidget 64 board has been collecting dust for some time while I worked on the wire harness and control linkages. But the fuselage is sitting in an unheated garage and with the most recent blast of cold weather I'm back in the house doing some of the small electronics parts of the build. I was going to buy my new windshield this month but may push that off and buy the servos for my flap indicator or dc motor for my auto pilot elevator trim wheel instead to give me a bit more indoor work. I can heat up the garage to allow for comfortable work with a portable heater but that's a pain.

    Re: Cessna 172 Annunciator Panel

    Hi Reid

    Just like to mention that i have great interest in the annunciator panel and enjoying the great input here, but there seems to be a problem with your pictures, when the links are clicked it says photobucket pictures removed, can you please check.

    Paul,

    It appears the photobucket links are bad now, I will check it out and repost the links later today. Thanks for the heads up.

    Re: Cessna 172 Annunciator Panel

    Thank you Reid

    These pictures are very good, they will help to understand your earlier post about the dimensions of the frame, I am certainly looking forward to the progress of this project and it's final outcome, as will many others.
