Thumbnails with Descriptions

 
Thumb and Description for Image 1:
This gallery depicts part of the assembly of our EFIS panel.
Some parts at the front, then the 3 panel parts:
From left to right: the printed panel, plexi backer, and the mounting plate.
 
Thumb and Description for Image 2:
Closeup of the printed panel. This actually consists of 3 parts: (front to back) a thin tranparent adhesive, normal white paper printed partly brown, and a inkjet or laser transparency printed black to block light (see other panel galleries for pics)
 
Thumb and Description for Image 3:
plexi backer (ours is actually not plexiglass, but something similar which is easier to work with)
 
Thumb and Description for Image 4:
and the back-plate. This is actually a double side copper PCB. Sturdier and it doesn't brake as easy as plexiglass et al.
 
Thumb and Description for Image 5:
some of the parts.
 
Thumb and Description for Image 6:
the PCB back-plate/mounting-plate
 
Thumb and Description for Image 7:
again the back of the PCB, with one rotary not mounted yet
 
Thumb and Description for Image 8:
front side of PCB
 
Thumb and Description for Image 9:
an interesting experiment: since both the ND Range and the ND Mode selectors have pushbuttons integrated, I tried to come up with a simple and cheap solution.
I drilled a 5mm hole into the white bottom part of the rotary. Now, the axis as a vertical play of about 1mm which can be used in conjunction with a microswitch...
 
Thumb and Description for Image 10:
... I got the small green microswitches really cheap (1.50 EUR for a bag of 100 :-)
And the size is just right for this. It only needs to be glued onto the rotary.
 
Thumb and Description for Image 11:
... just soldering wires the the contacts of the microswitch is not that easy.
 
Thumb and Description for Image 12:
different angle
 
Thumb and Description for Image 13:
This should show it nicely
 
Thumb and Description for Image 14:
and again another angle
 
Thumb and Description for Image 15:
putting the whole thing together... plexi backer
 
Thumb and Description for Image 16:
again
 
Thumb and Description for Image 17:
printed panel laid on top.
 
Thumb and Description for Image 18:
the whole thing screwed together and adding some knobs
 
Thumb and Description for Image 19:
I know, the knobs don't match, but better than nothing right now :)
 
Thumb and Description for Image 20:
backlighting test: 4 yellow 3mm LEDs dangling between the plexi and the mounting plate.
 
Thumb and Description for Image 21:
even visible in daylight.
