This application is designed to allow Raspberry Pi single-board computers to be mounted on binoculars (or, really anything like that...telescopes for instance). It uses the RPi GPIO interface to read input signals from momentary buttons (wired to GPIO/BCM 22 & 27), and output status to two LEDs (GPIO/BCM 17 & 24).
Pinoc relies on the use of a Raspberry Pi camera module, which wires directly into the board via ribbon cable. It uses the picamera Python 2 module to interface with the hardware.
The software for this system centers on a small python app called pinoc.py, which is located in the code/ directory. It can be installed using Ansible, via the playbook in the ansible/ directory. You'll find instructions for installing the software (including using the Ansible playbook) in the README.md under code/.
The software README also contains instructions for wiring the buttons and LEDs to the RPi.
In addition to software, you also need a place to hold buttons, LEDs, a Raspberry Pi, and a battery. The CAD and STL files for those are contained in cad/ and cad/stl/, respectively. See README.md under cad/ for more information on how to use those files.
