Nikon makes some pretty sweet cameras but seem to be stuck in the dark ages with some of their accessories. The WT-# series of accessories cost over $1000 with software work only with specific cameras to allow complete wireless control of your high-end camera.
Nikon recently released the WU-1A, a consumer version of a similar capability for a much lower price, but it's sadly tied to a horrible feature-crippled android/iphone app. This talk will go over the process of assessing and reversing the involved hardware and software, show what capabilities and limitations are technically induced or marketing induced, and start the process of developing some feature-rich tools and open source software to make it into a reasonable replacement for the WT-series adapters.
