Project PANOPTES provides instructions and a parts list for a complete PANOPTES unit. However, it's important to note that there are potentially many alternative ways to build various parts of the unit.
At the top of each section you will find a "Functional Requirements" table lists the actual tasks that are needed for that specific piece of hardware or software.
A good example would be specific weather proofing tips for your climate that might not be covered by the official guides. The Functional Requirements for weatherproofing are: a) don't let your PANOPTES unit get ruined by the weather (or bugs)! and b) weatherproofing materials should not interfere with the movement of the mount.
We offer a working solution on how to do that with specific tools and hardware, but as long as you are able to satisfy the Functional Requirements for each section, feel free to explore better (or cheaper!) options.
