    how to backlight.

    the process of making "integrated style backlighting" in panels is probably easier than placing leds or globes in a make shift style behind panel hardware.

    materials.

    copper pcb blank.
    soldering iron.
    aircraft panel.
    grain of sand or micro minature bulbs 3, 4, 5, 5, 12 volts etc.

    1 drill your 2-3mm holes halfway though the rear of your panel where the light will distribute evenly.

    2 using the same holes, drill a 7-8mm sink hole a quater way though the rear of panel.

    3 use some tracing paper to trace the holes you have drilled and the panel shape.

    4. the panel needs to be divided into two parts. a postive power side and a negative side. to do this we use a thin grinding wheel or an engraver to remove the copper in a thin line on the pcb blank. this line must divide each light bulb point on the plate. so if we have seven bulbs required then we have to engrave a line though all of those seven pionts in a loop. this is so that the lightbulb legs can be in the correct postition and each tiny leg can be soldered onto opposite polarities.

    5. there also needs to be a small power connector in the circuit somewhere. dill two tiny (1mm) holes on either side of the ground out loop at a position of your choice. poke a twin pole connector through the copper board and solder the legs on the back. the corresponding area on your aircraft panel may also have to be ground out to accomodate the solder lumps...just like the drill holes for the bulbs.


    this method is suprisingly easy. the lower du panel in the pic took me about 3 quaters of an hour to make. and it cost about 3 dollars au. the bulbs come from china for about 20 cents au each.

    any questions class?

    ye of little faith.
    its easy andy.

    some of you guys must have pulled your "manufactured" panels apart "just to see how it works".

    i did.

    the toughest part is obtaining the right size bulbs.....ebay....china.

    they are usually used in model train setups as street lights or in doll houses (that should help with the leg work). fairly expensive from the local model train shops at 5 dollars each but. you can get em off ebay for ten cents or twenty cents each....go china!

    its a flightdeck solution of my own.

    patents???...yeah right.

    backlighting

    Cool,I use the same method accept,I do the copper etching method for the traces maybe tack on 20 more minutes to the whole thing and its done.Surprisingly its not hard as I thought and the results are excellent.If any one has the patients its well worth it.Soldering is easy to,I use the Cold Heat soldering gun and its so fast!!

    David,

    This looks like a great way to do the backlighting.
    I'm having a little trouble with your explanation on how you did it.
    Are you saying to drill part way through the Aircraft panel?
    I'm using old FDS panels (not IBL) there is a gap between the backers and the front panel would I still need to drill the "back of the front" ?
    Also what voltage did you use and do you use resisters anywhere?

    thanks

    Paul

    From the responses it sounds like a great idea, but i need pictures. The explanation confuses me. thanx What panels are you using or did you make your own?

    Hey builders I did make a video on how to do this type of back lighting for the Lear panels using just simple hand tools. Give me a few days and I'll post it. Pretty simple stuff!

    How are they coming along Joe? Did you figure out how you are going to price the Lear Panels yet and when they would start becoming more widely available?

    Thanks,
    Scott

    a panel as thick as an fds signature panel would be best. i have also glued white or clear plastic onto the rear of thin elite style panels aswell. works a treat.
    sorry about my explanation. fairly rough.

    see this
