Citizen Dialog Kit includes technical tools and a complete workplan. You can find more information about the work plan on the Methodology-page.
The Citizen Dialog Kit consists of off-the-shelf hardware, firmware and a back-end setup to manage your polling and visualization devices. For the latest version of the documentation and code, visit our Github page.
On the Github page you will find:
- Off-the-shelf hardware components list,
- E-ink display firmware for polling and visualization (C++, Arduino based),
- Back-end solution and API for display management (Node JS based),
- Vector designs to laser cut enclosures for the devices out of plexiglas (pdf),
- White-label designs to add color, call-to-actions or branding to your devices (pdf).
You can find a more illustrated version of the technical documentation in this booklet.
We use e-ink displays to minimize power consumption. Together with 3G connection through Particle.io microcontrollers, the polling and visualization devices are easy to install and move.
The main components are:
- Particle.io Electron 3G microcontrollers
- WaveShare e-ink displays (7.5 and 4.2 inch, black-white, black-white-red, black-white-yellow supported)
- Voltcraft Solar powerbank (8000 mAh)
The Particle.io microcontrollers run Arduino code. They check-in with the back-end according to their schedule to receive new content and to submit polling results.
The back-end is based on Node JS and a MySQL database. The display management API allows you complete control over the displays, their scheduling and polling data. The API uses basic authentication for all non-GET calls.
The repository includes some convenient back-up scripts and a basic content management system.
