My setup
What I work with
My AI server, my work machine, what I record videos with, and the scanner for my mail. This page only lists what I use myself, plus my books.

My work machine. I dictate without an extra microphone, straight into the MacBook, with VoiceInk.
Video

Sometimes I record with the iPhone, sometimes with the Sony.

The camera when it is not the iPhone.
DJI Mic Mini
The wireless microphone for sound.
