Ok you are ready for Wireless Streaming POV.
Update: a more detailed post with actual wifi streaming code (PC or Android) is available now on my website:https://www.circusscientist.com/2018/07/23/lets-stream-some-pixels/
Update 2020: all code and hardware is now open-sourced. See https://circusscientist.com for details
let me know what you think!
