While this project uses a Libre Computer Renegade and not a Raspberry Pi product, the two are relatively similar, hence organizing this project with my other Raspberry Pi projects. I chose to use the Renegade for this project as it was less expensive than a Raspberry Pi 4. Additionally, a Raspberry Pi 3 would not work for this project as USB 3.0 is needed for the stereoscopic camera. 4GB of RAM is also desireable for writing video footage into RAM when recording.
Version 16 of the C source code records stereoscopic footage to a RAM drive and after recording completes, the recorded video file is moved to the connected USB flash drive. Version 17 of the C source code records stereoscopic footage directly to the connected USB flash drive, and thus requires that you have a USB 3.0 hub connected to the Renegade's single USB 3.0 port, and the cameras module and USB flash drive connected to the hub. While that adds clutter to the setup, it allows for more efficient recording without waiting for footage to move from RAM drive to USB storage. You will need a high performance USB flash drive though. I'm using a PNY 128GB Elite-X Fit USB 3.1 flash drive with a UGREEN USB 3.0 4-port 0.5'-corded hub.
