Disney Flix Camcorder, ~2007 vintage

Surprisingly, this toy camcorder made for an interesting teardown.

Given the bare-bones simplicity and working serial port, it could be a worthwhile target to reverse engineer the Zoran Coach architecture. Zoran Coach for a while was the dominant SoC found in many consumer point & shoot cameras of the late 2000s to early 2010s. https://en.wikipedia.org/wiki/Zoran_Corporation was bought by CSR, who was then later sold off its camera IP to Qualcomm.

The camera is also unique, in that it isn't a rats nest of flat flex cables, but mostly uses right-angle pin-headers as interconnect between circuit boards (the exception being the display). This will make it easy to tap into signals between image sensor and SoC, or to automate camera controls with an MCU.
