Built a second ALDLgauge for my '74 Jaguar.

I used an original Jaguar gauge case because I wanted it to match the others in the dash. I'll replace the cars voltage gauge with the ALDL gauge.

Stuffed inside the case are: 128x64 OLED display, 16 segment Adafruit "NEOpixel Ring", two Arduino Pro Mini's and a 12v to 5v DC-DC converter. External to the case are the bluetooth transceiver (I'll put some heat shrink around it before installation) and a rotary encoder. Only three wires to connect it to the car, ground, power and ALDL.
