Feiyu Gimbal Serial Hack – scanlime:021

Join this reverse-engineering journey where I wind through software and hardware in a Feiyu Tech Mini3D gimbal, in order to give it serial controls more suitable for my Tuco Flyer robot project. I start out by taking apart the wire protocol used by the settings app, then after accidentally breaking the gimbal we have to dig deeper into the firmware to fix it again.

scanlime:007 / USB Disk Recorder Part 2

Continuing the adventures from Part 1, this video wanders along several tangential paths, trying to get some data out of this device worthy of reversing. This time we spend a bit more time in IDA looking for Z80 code, tinker with SCSI trying to break things, and we even do some necromancy in trying to get grumpydisk working.
