Use your 3DS as a networked webcam with this homebrew (and a nifty python script)
Uses the sounddevice, qoi, and pyvirtualcam pip packages, which require you to have OBS and VoiceMeeter installed.
On Windows, at least. If you use any flavour of *nix, you should know enough to make it work.
Launch the 3DSX from the Homebrew Menu on your console, set it up how you want (microphone/camera/both)
Start the connection
Run the script with your console's IP address as the only command-line argument
When you want to stop, stop the connection on your console or exit directly.
WARNING: The instructions mention push-to-talk, but it's not implemented yet!
