Garmin GNS 30
The aim is to produce a hardware simulation of the Garmin
GNS 530, using the Microsoft Flight Simulator add-on from RealityXP, replacing
the on-screen switches with physical devices.
Front Panel Design
The panel was designed using Front Panel Designer and
fabricated by Schaeffer AG in Germany.
The image will be displayed on a 5 inch colour LCD
display removed from a Sony PSone.
A PCB was designed to hold the push button switches and
fabricated by a company in Ireland.
The PCB was mounted on the front panel and used to hold
the 5 inch LCD screen in place. Pair of dual concentric rotary encoders were fabricated
from CTS288 devices, gearing and bent metal.
The PSone electronics to drive the LCD screen were
attached behind the switch PCB.
The design was refined by replacing the fabricated
concentric encoders with a better design and adding an electronic interface to
enable the use of a VGA input rather than composite video.
The electronics interface to Microsoft Fight Simulator is
achieved using a single MasterCard from Opencockpits to provide and
interface to the switches and rotary encoders.
