SDIR: Software Defined InfraRed

Presented at Kiwicon X: The Truth is In Here (2016), Nov. 18, 2016, noon (30 minutes)

There have never been more infrared signals, from the remote control toys and televisions that we all know, to audio distribution systems and unintentional emissions from electronic equipment. Off the shelf receivers have helped people to decode signals in the past, however these existing techniques lack the ability to detect high speed communication signals without prior knowledge of protocol. Using low cost hardware that anyone could put together, we have been able to apply Software Defined Radio techniques to infrared signals.  In doing so, we are able to detect and interpret unknown infrared communications and emissions, opening the door to a new era in exploration. As a proof of concept, I'll demonstrate how anyone can reverse engineer a simple IR protocol using hardware that they can build at home.
