VGA HARDWARE HACKING TUTORIALS
I began working with VGA cables after seeing a Dorkbot Chicago talk by Arcanebolt (Mark Beasley and Tamas Kemenzcy) in 2008. My first VGA hack was made for Die Computer, and the hack was further developed in my VGA Audio Video Synthesizer and in Cracked Ray Tube. The tutorials below are designed for people with little to no experience with electronics; a basic understanding of soldering is all that's needed.
