Baron 58 Cockpit Simulator

Adapting an Aviation Headset to a PC Sound Card

Intro

I have three aviation headsets for my use as well as the use of my passengers. Inspired by Alan D. Bryant's article (reference below) I now use one of the headsets for the simulator (for on-line flying with VATSIM etc)

Results

Inside view: everything built inside a small box	Top view: Left the connectors to the PC and the 9V DC power supply connector; right the headset connectors a on/off switch and a on/off indicator LED
Front view: headset connectors (jackplugs and busses), on/off switch and indicator led	Back side view: the 3,5mm jackplug connectors to the PC and the 9V DC power supply connector;
