This section tracks other open source avionics projects, for the purpose of collaboration and design reuse. Please let me know if you know of any other initiatives.


After being idle for a few years, the MakerPlane avionics section gained some momentum again between early and middle 2016. Their Python (PyQt) EFIS GUI looks quite good. (switch to the 'develop' branch)


Their FlightBox is a ADS-B / GPS / AHRS data to Tablet / Phone interface. It consists of a Raspberry Pi with USB Dongles: 2x SDR, WiFi. AHRS expansion port.

Compatible Apps: WingX Pro, iFly GPS, FlyQ EFB and FF.

Marian Keller - AHRS platform for gliders

Bluetooth module for smart devices.

Experimental Avionics - Arduino EFIS

Looks very promising. Second prototype already. Updated end of 2016.

Marc Robitaille - Arduino EFIS

Altimeter, Airspeed, Horizon, Slip, Vertical speed

YouTube Link (with dropbox link in description)

FlightGear Flight Simulator

Open source simulator (similar to Microsoft Flight Simulator). Might be useful to use some of their front end / GUI.


Forum to discuss. Maintainer longer has aircraft. No content on website;

Arduino Altimeter

Activity between 2003 and 2005. OpenGL + Qt. Download able ‘efis.0.1.1.tar.gz’

Density Altitude Gauge; no source code, never completed?

Source code for MGL Avionics - Ultra HXL was released, but just dead links now.
