These files produce the case for the Airduino 4.3 Beta, an open source experimental Primary Flight Display (glass cockpit) for experimental aircraft. At this point, this project is still very much in Beta testing. Please visit the link above for more information about the project.
The files are as follows:
- AirduinoBezel. This is the front face of the instrument. Print as shown.
- AirduinoLayer2. This screws to the back of the bezel, and cradles the Arduino Mega 2560 and screen. Flip over to print.
- AirduinoLayer3. This is glued to the back of Layer2. It is printed this way to eliminate as much support structure as possible. Flip over to print.
- AirduinoBatteryPowerCover. Not used in the current version of the Airduino, but as development progresses, it may be. Print as shown.
- AirduinoPitotStaticCover. This is attached to the back of Layer3 with silicone sealant and screws. It provides airtight seals so that the air data chips can sense the pitot and static pressures. Print as shown.
- AirduinoSensorHolder. Optional part that I use to hold the battery and any other convenient chips (such as AHRS) when the system is not yet mounted in a vehicle. Ribs should face up while printing.
- AirduinoKnobs. These are knobs for the encoder switch. They all have slightly different diameter shaft openings to allow you to find one that fits well. Openings should be down to print.
Note that this is a BETA project, and its accuracy is only as good as the digital AHRS you use. The completed project is shown in a stationary ground trainer used by Southern Illinois University as a recruiting aid.
These files are drawn in Autodesk Inventor, which exports STL's at 10% size for some reason. You will have to scale them up 10X. Print them with the faces in downward position against the glass to eliminate MOST of the necessary supports. Layers 2 and 3 are glued together. I have had very good luck with all purpose plumbing cement (PVC, CPVC, ABS, etc).
There are instructions
Overview and Background
This is the case for the Airduino 4.3, and quite possibly the future Airduino Engine Information System coming in the fairly near future.
Lesson Plan and Activity
This would be appropriate for an electronics class, or for aviation classes.
