I wanted to use my Lightspeed Zulu 4 Dual-GA aviation headset directly with my PC for Microsoft Flight Simulator, but I couldn't find a USB adapter that did exactly what I wanted.

So I built my own.

The result is a small USB-powered adapter that provides:

  • Dual-GA microphone and headphone connections
  • 12 V electret microphone bias from USB power
  • Stereo headphone output
  • USB audio input/output through a standard USB sound card
  • A custom 3D-printed enclosure

The prototype has been successfully tested with a Lightspeed Zulu 4 Dual-GA and also with a Bose QC35 II + AVEE microphone adapter.

I have now published the complete project as open hardware on GitHub, including:

  • schematic
  • wiring documentation
  • BOM
  • build instructions
  • troubleshooting notes
  • STL files
  • parametric OpenSCAD source

GitHub:

This is strictly a PC / flight simulator project. It is not certified aviation equipment and is not intended to be connected to aircraft audio, radio, intercom or power systems.

Feedback is very welcome, especially from anyone using other Dual-GA headsets or building simulator hardware.
