Got a Raspberry Pi hooked up to the LCD display for my 737 Flight Management Computer CDU. Had to solder a 5.5mm DC Jack for the 12VDC power, and also buy a (MYR 49 rip-off!) HDMI-to-VGA converter.

The 5" 4:3 TFT LCD display (https://goo.gl/sFTShF) is nice and has good viewing angles. It is slightly defective ... it only works when the ribbon is bent 180 degrees back behind the display. If it's flat downwards, the display is erratic. Since I would need to pay to ship it back to claim warranty, I figured I'll live with it -- after all I *will* be mounting it with the ribbon bent 180 degrees back anyway. Hopefully that's all there is to it.

It turns out I also need a VGA cable. So for now I have this 1.5 meter thing to connect two connectors that are going to be inches apart in the end. I've found a USD1.39 DSUB VGA Male gender changer on eBay which I think will allow me to eliminate the cable.


I googled enough graphics programming to figure out how to fit the FMC's layout into the screen. The 737 FMC display is interesting in that despite being a late 1970s thing it combines two different font sizes on the same screen. There are alternating rows of full-height and half-height characters. The buttons at the side of the display are supposed to align with the full-height rows (like an ATM has buttons next to the screen). I think whoever designed the 3D model should have made the buttons a bit lower. But I don't know enough to mess around with the 3D object to fix it, so it's another thing I will live with.
